The Poultry Research Centre continues striving for excellence in research and learning in partnership with the poultry industry, Alberta Government, the UofA and funders. The Centre is committed to development of value-added poultry products and technologies and sustainable production practices. The industry support for the Centre has been growing. Three egg processors, IRI Canada Inc., Burnbrae Farms, and Sparks Eggs, joined the long list of the PRC’s industry supporters. The Board of Directors was enriched by another voice from Ontario. Dr. Helen Anne Hudson from Burnbrae Farms joined the PRC Advisory Board of Directors. We are looking forward to working with Helen Anne in building stronger connection with the poultry industry across Canada. In the fall of 2006, the Poultry Research Centre Advisory Board of Directors recommended that the Centre undertake steps to strengthen its biosecurity. The Centre houses very valuable research flocks. Protecting the health of the PRC's flocks means safeguarding industry and public investment in the PRC and its research activities. Last year, the Poultry Research Centre secured funding from the Canadian Food Inspection Agency and Food Safety Initiative (Alberta Agriculture and Rural Development) and retrofitted its current facilities with improved biosecurity measures. By addressing biosecurity concerns at their own facilities, the Centre joined a growing number of responsible poultry operators contributing to national biosecurity efforts.
The Poultry Research Centre has a strong record in taking research results out to industry for implementation. With the addition of researchers to the ‘value-added’ area over the last two years, the Centre has expanded its capabilities to enable industry to partner further in the discovery of specific knowledge that could lead to technologies or products with potential for commercialization. I would like to express my appreciation to the board, the Poultry Research Centre signatories, funders and the government for their commitment to the Centre and its efforts to strengthen the poultry industry through research, development and technology transfer. I would like to thank Robin Horel and Lloyd Johnston, two board members whose term expired this year, for their dedication and contribution to the success of the Poultry Research Centre. I look forward to working with the Poultry Research Centre team again this year.
Steve Howe, Chair
In November, researchers participated in the Alberta Poultry Industry Research and Development Strategic Priorities Forum in Edmonton. This forum was organized by the poultry commodity Boards: Alberta Chicken Producers, Alberta Egg Producers, Alberta Hatching Egg Producers, and Alberta Turkey producers in association with the Alberta Livestock Industry Development Fund. Dr. Helen Anne Hudson was a key note speaker at the event. The main goal of the event was to establish direction of future research and development investment for the Alberta Poultry Industry. The priorities identified by the industry and funders will help the PRC researchers to continue to focus their research activities on issues that matter to the poultry industry.
Welcome to the Poultry Research Centre! It is my pleasure to share with you our accomplishments and highlights from activities at the Poultry Research Centre in 2007-2008. The excellence in research and learning at the Centre continues. In 2007, the Centre’s family included 13 researchers from the U of A and Alberta Agriculture, six Post Doctoral Fellows, one Research Associate, 32 graduate students and 11 technicians working on 34 research projects. Together, we are a multidisciplinary team, with strengths that span from Embryology and Chick Quality, Metabolism and Reproduction, Feed and Nutrition, Management and Physiology, and Bioeconomic Modeling to Egg and poultry meat - new product and process development. The new value-added group, Drs. Betti, Wu and Renema, developed their research programs, secured research funding and partnered with the industry. Their graduate students, Postdoctoral Fellows and technicians, commenced research projects aiming at developing technologies that will add value to poultry products. In the past year, our researchers and students have delivered presentations at 33 conferences, 81 scientific and industry meetings and published 17 research papers in peer reviewed journals. They traveled to the US, China, Australia, Japan, Central America, and across Canada and Alberta to share and learn about innovations in poultry science and to bring this knowledge back to the Centre. They have also met with industry across Alberta and Canada to listen to industry issues and concerns. I would like to thank my colleagues for their contributions to the success of the Poultry Research Centre this year. I would also like to thank the Poultry Research Centre Advisory Board of Directors for guiding the Centre in the new direction of value-added research.

We are very proud of our students!
“Growing quality… today and in the future” The delivery of a quality product to the consumer requires the dedication of everyone in the value chain. Poultry Research Centre scientists participated in the Alberta Chicken Producers Research Symposium entitled “Growing quality… today and in the future.” The scientists presented information on topics ranging from chick quality and broiler nutrition, to meat and bone quality, and value-added product development.
The PRC’s Biosecurity is for the Birds In 2007, the Poultry Research Centre initiated an ambitious project focused on biosecurity, which was supported in part by the Avian Biosecurity Technology Development Fund (Canadian Food Inspection Agency) and the Alberta Food Safety Initiative (Alberta Agriculture and Rural Development). The project sought and continues to improve biosecurity both at Centre’s research facilities and on commercial poultry operations in Alberta (and beyond). The first phase of the project focused on characterizing and addressing potential threats to the Poultry Research Centre’s research unit located on the University of Alberta’s south campus farm. This process was led by a
committee which included staff and researchers at the Centre, as well as Dr. Tom Inglis of Poultry Health Services Ltd. (Airdrie, AB). This phase of the project saw numerous enhancements to the Centre’s internal biosecurity. The most visible enhancement was the installation of a perimeter fence with a single access point, designed to control access of vehicles and people to the barns. Other notable improvements include, dedicated transitional areas (or anterooms) for each barn, keypad locks for all external doors and a screening policy for all A view of the perimeter visitors to PRC along with a fence installed as part of visitor questionnaire. While PRC’s biosecurity retrofit improvements are still ongoing, those already made have addressed many of the biosecurity challenges the PRC faces as part of day-to-day operations. The second phase of the project involved developing educational materials and learning opportunities for commercial poultry producers with the aim of improving biosecurity in the commercial industry. There One of two biosecurity were several notable workshops for producers achievements in this phase, including: • An educational DVD that outlined critical components of an on-farm biosecurity strategy. • A producer manual designed to assist producers in identifying and addressing gaps in biosecurity on their operations • Two biosecurity workshops that attracted nearly 40 producers interested in learning more about what they can do to protect their operations from disease outbreaks. For more information about PRC’s biosecurity project, please contact the project coordinator. Matt Oryschak by email firstname.lastname@example.org or 780.492.7694.
Raising the Henhouse Roof – A Special 50th Birthday Party Who says we can’t mix research and fun? Not Dr. Frank Robinson and a group of researchers from the Centre who on November 20th,2007, organized a most unusual 50th birthday party for … chickens. By celebrating a genetic strain developed in 1957, the event brought publicity to the living collection of poultry history maintained for over 15 years at the University of Alberta. The program recognized the contributions of six invited Canadian poultry geneticists involved in the development and maintenance of the historic strains: Dr. Don Shaver (former CEO of Shaver Poultry Breeding Farms), Dr. R. Crawford (Professor emeritus, U of Saskatchewan), Dr. Robb Gowe (formerly of AAFC), Dr. Ed Merritt (formerly of AAFC), Dr. Allan Grunder (formerly of AAFC) and Dr. Jim Chambers (AAFC).
Drs. Grunder, Crawford, Merritt, Shaver, Gowe and Chambers (left to right) at the 50th birthday celebration Poultry Research Centre researchers reported on past and recent uses of some of the 10 valuable strains in research programs that have contributed to the progress of the poultry industry, including the improved production efficiency of today’s chickens. “Eggcited” About Summer This past summer, Dr. Fasenko’s research group participated in the WISEST (Women in Scholarship, Engineering, Science, and Technology) Summer Research Program, which saw two high school students join the group for the duration of the 6 week program. Here is how Aleksa Leszczynski, one of the WISEST students, described her experience:
"Life at the poultry unit actually is thrilling! So many times I have been asked why someone would want to research chickens? I respond with the question 'what did you eat for dinner yesterday?' I now have conclusive evidence that often the answer to this question will be well... chicken'. Many of the projects conducted at the poultry research centre are working to study and improve the animal that we just love to eat!”
There’s a Heifer in the Headlines November 6th, 2007 – Northlands FarmFair The Heifer In Your Tank (HIYT) event, organized by Dr. Frank Robinson and Dana Penrice, has become a tradition in Alberta, attracting new generations of students from the U of A and from Junior high schools who twice a year invite the public along for an evening of learning and laughter. The main objective of the event is to increase awareness of issues in agriculture and food production in youth, university students and the public through engaging them in learning experiences that are entertaining and humorous. The event provides science answers to questions you didn’t know you had about animal agriculture. The Fall 2007, UofA students from ANSC 200 class entertained an audiences of 600 in Edmonton. The Avalon School jazz band of 40 students added musical flavour to the event and the Hillcrest Jr. High Grade 7 class gave their own HIYT presentations.
There’s more of the Heifer…… Heifer in Your Tank - School at the U, where Grade 7 class from Hillcrest Junior High spent a week at the U of A Farm to learn about the agriculture industry and some of the issues it faces. Throughout the week, the class came up with questions they could answer about animal agriculture and presented their HIYT to the peers. There’s a Heifer in your Classroom, according to students from Lendrum School in Edmonton. Current and former Animal Science 200 students helped Grade 6 classes to develop their own questions about animal agriculture and presented their answers at an evening performance for their fellow students at Lendrum School. To learn more about “There’s a Heifer in Your Tank”, visit the HIYT website at: www.hiyt.afhe.ualberta.ca.

Research Highlights A. Embryology and Chick Quality Does the age of parents affect quality of offspring? FASENKO – Data from a collaborative study examining the effects of breeder parent age on fertility, embryonic mortality, and broiler chick quality is currently being analyzed. This project examined factors attributed to the rooster and the hen and how they affect chick quality and performance. The outcome will provide information on whether fertility and chick quality problems can be attributed to the male breeder, female breeder, or both parents. Team: M. MacKenzie, J. Wilson (University of Georgia), M. Wineland (N. Carolina State University), and D. Froman (Oregon State University)
Parental age affects poult metabolism FASENKO -- Research was completed to examine embryonic metabolism in two modern turkey genetic strains (Nicholas and Hybrid) at 4 parent flock ages. This research determined that embryonic metabolism per unit of embryo weight decreased as parent flock age increased. This means that to gain 1 g of body weight, embryos from younger breeder flocks need to metabolize at a higher rate than embryos from older breeder flock, putting embryos from young flocks at risk of overheating. Team: G. M. Fasenko, J. A. Hamidu (PhD Student), and J. J. R. Feddes
Eggs with Holes…Can they hatch? FASENKO – A study was recently completed that examined the effects of the hole made by an in-ovo injection machine on hatchability of turkey eggs. The results of this preliminary study found that simply making a hole in the egg with the in-ovo machine did not affect hatchability or poult quality.
composition of eggs and yolk sacs in two common commercial broiler breeder strains. Results showed differences between fat contained in the egg and fat contained in the yolk sacs of chicks hatching from young broiler breeder flocks compared to eggs and yolk sacs from mature and old flocks. Chicks hatching from young parent flocks may have a disadvantage in fat reserves when compared to chicks hatching from older flocks, and this difference may influence chick growth and performance. Team: A. Franco, D. Korver and G. Cherian
New techniques: A novel method to assess intestinal villi FASENKO -- A novel technique for measuring intestinal villi development in broiler chicken embryos (last 3 days of incubation) and broiler chicks (first 3 days of grow out) was investigated. This project provided researchers with information regarding normal intestinal villi growth. This technique for measuring intestinal villi can be applied in further research projects on chick quality. Team: A. Franco and A. Leszczynski
Belly button condition affects intestinal development FASENKO -- Research is underway to analyze the effects of small navel buttons in broiler chicks on intestinal development during the first days posthatch. Early result show that the intestine of chicks hatching with small navel buttons developed slower than the intestine of chicks hatching with healed navels. Because intestinal development is important for nutrient absorption, even small navel buttons affect chick quality and potentially, chick growth and performance. Team: A. Franco and L. Kawalilak
Parent age affects chick quality by affecting fat in yolks FASENKO -- Research was conducted to study the effects of broiler breeder flock age and egg size on the fatty acid
A. Embryology and Chick Quality (cont.) Evaluation of techniques to assess chick quality RENEMA â€“ Several studies have recently been completed as part of an ongoing exploration of the relationship between chick quality and growth. One of the best predictors of inferior quality is the presence of red hocks (red patches on back of hock joint of the leg) and/or redness on the beak near the nares (nostrils). Both of these conditions indicate the chick struggled getting out of the shell and is now less likely to survive or thrive. What test was the least useful? The reflex test, which measures how fast a chick can right itself when placed upside-down, was never found to correlate with any production traits. Team: R. Robinson, L. Romero and A. Naeima
B. Metabolism and Reproduction Maternal feeding strategies to improve uniformity ROBINSON â€“ A project is currently underway to test the effects of broiler breeder feed and management strategies during the growth phase on flock uniformity. Treatments include everyday and skip-a-day feeding, scatter feeding (broadcast feed on litter), feed dilution, and bird sorting. By creating a more uniform group of birds at the point of transfer to the breeder house, we feel that we will be able to create the foundation for more uniform chick quality and early production traits. Early results show very positive effects of bird sorting on overall flock uniformity Team: D. Holm, F. Robinson, R. Renema, M. Zuidhof, and A. Pishnamazi
Manipulation of protein during growth affects breeder development RENEMA -- In a trial now in the final stages of analysis, dietary balanced protein was raised or lowered by 3% during key broiler breeder developmental rearing periods. With lower protein, both the fat stores and relative ovary weight increased early at the end of the test period starting from the 13-18 wk period, and the difference grew even larger after this. Skeletal development and body composition was most affected by high dietary protein during the 1 to 7 wk and 19 to 25
wk periods. Interestingly, these were also the periods that did not have a long-term effect on reproductive development, indicating that factors affecting support of ovary development are more important. The exception would be overfleshing, which in the long run diverts nutrients from reproduction to support this energetically-demanding tissue. Team: R. Robinson, L. Romero, A. Pishnamazi, and M. Zuidhof
Understanding breeder male condition and performance ROBINSON -- The final report for a project evaluating male:male aggression, growth, and survival in a commercial setting has been submitted. Males demonstrated a tight relationship between body weight and relative breast muscle, fatness, and testis weight up to peak production. Considering how variable we found the growth profile of individual birds can be within the population, the strength of this relationship between body weight and testes weight (which is closely linked to sperm production traits in younger birds) was somewhat surprising. A body weight of 3 kg was the threshold at which spontaneous testicular development began. Team: R. Renema, and N. Wolanski
B. Metabolism and Reproduction (cont.) Does rooster age affect sperm quality and fertility?
Goundbreaking work in understanding broiler breeder energetics
FASENKO – A summer student research project was conducted to determine the effect of rooster age on sperm movement, concentration and fertility. From this preliminary research it was concluded that rooster age affected sperm quality (mobility was higher in younger roosters but older roosters produced more sperm cells) but did not impact fertility.
ROMERO -- We have recently had success applying statistical nonlinear mixed models to calculated residual feed intake (RFI) in broiler breeders. These models can cope with changes due to age, weight, rate of lay and many other factors. This has allowed us to differentiate between birds naturally more or less efficient than predicted. However, Romero has now perfected the model even further by allowing it to remove potential bias due to feed intake (birds consuming less appeared more efficient) by calculating the residual maintenance requirement (RMR). This is groundbreaking work in broiler breeder energetics. It shows a lot of promise in its potential application to exploration of relationships between maternal efficiency and broiler offspring production traits.
Team: D. Weuster and M. MacKenzie
Does semen quality and composition change with rooster age and storage time? FASENKO – A study is currently underway to investigate the effect of male age and semen storage length on sperm motility, semen protein composition, and fertility in broiler and turkey breeders. The expected outcome of this project is that we will be able to identify proteins in the semen that can be attributed to quality (good or bad) so producers may have another tool to distinguish between low and high quality males. This research is scheduled to be completed in 2009.

Team: M. MacKenzie, N. Kav, M. Dyck, M. Bakst (Germplasm & Gamete Physiology Lab, ARSUSDA), and D. Froman (Oregon State University)
Efficiency in broilers linked to efficiency in breeders ROBINSON – A study to investigate linkages in broiler breeder efficiency with efficiency and meat quality traits of broilers was recently completed. The highly productive graduate students will publish 10-12 papers between them for this work. In addition to new statistical models to assess hen efficiency, they have also identified a period 7-10 days before a hen lays an egg in which she predictably becomes extremely efficient. Once the first egg arrives, efficiency returns to normal. These birds appear to have a natural tendency to utilize carcass stores during final ovary formation – a process that corresponds to very high estrogen levels, which may override some of the inhibitory effects of some of the other metabolic and growth hormones at this time. Team: L. Romero, A. Naeima, R.Renema and M. Zuidhof
C. Management and Physiology Immunity in chickens has changed over the last 50 years
Welfare considerations: Group sizes for laying hens in furnished cages
KORVER – Investigation into the differences in immune function, and protein metabolic response to inflammation in modern and 1957 random-bred chickens is underway. Korver’s group have found that modern birds regulate the immune system differently than the random-bred birds. An increased understanding of the chicken immune system is important to be able to react quickly to any potential changes in the way growthpromoting antibiotics are used in Canada.
HALEY -- This collaborative project began in 2006 and final reporting has now been completed. The study confirms the strong preferences of hens for using nest boxes and perches. One trade-off that needs to be considered is that providing these amenities resulted in birds having less feather cover at the end of the laying cycle. Team: N. Cook (Principal Investigator, Alberta Agriculture and Rural Development), J. Feddes, D. Korver, J. Church
Understanding laying hen medullary bone metabolism KORVER – Progress is being made to investigate management factors prior to first egg that may increase skeletal quality over the laying cycle in laying hens. Caged-layer fatigue (osteoporosis) is not necessarily due to an overall loss in bone tissue, but rather a redistribution of structural bone over time.
D. Feed and Nutrition Maternal and dietary 25-OH D3 on broiler innate and cellular immune response
Availability of methionine sources for broilers
KORVER – Korver and Saunders-Blades (Ph.D student) are investing the use of 25-OH vitamin D3 on broiler breeder productivity and health, as well as chick quality and immune function. They have found that prior to 10 days of age, broiler chicks may have an impaired ability to convert dietary vitamin D to the active form used in the body.
KORVER – Research is underway to compare two commercially-available methionine sources for biological activity in chickens.
E. Education and Learning Innovations in the Poultry Industry ROBINSON – Robinson and Penrice led an initiative to produce a series of DVDs highlighting innovations in the poultry industry. This well-received DVD and booklet combo is now available and provides valuable information to the public, educational groups, and will help producers explain what goes on every day in primary production of poultry products.
F. Meat and Egg Products Optimization of Omega-3 chicken meat enrichment ZUIDHOF --An optimal scenario for enriching breast meat from 35 day old broilers to level where a claim ‘source of omega-3 fatty acids’ can be applied to the product is to provide broilers with 17% dietary ground flaxseed meal for 15 days prior to processing. A second optimization scenario was discovered. Broiler dark meat has a lower monetary value than breast meat in current markets. It can also be enriched with Omega -3 polyunsaturated fatty acids (n-3 PUFA) much more easily than breast meat. Thirty-five day old broilers fed either 10% flaxseed meal for 8 days, or 17% flaxseed meal for 4 days prior to slaughter had thighs with levels of n-3 that exceed the threshold required to label the meat ‘source of omega-3 fatty acids’. Using this strategy, there is little (no statistically significant) negative economic impact on production (7% increase) and no negative effect on yield. Team: M. Betti, T. Perez, D. Korver, V. Carney, B. Schneider, W. Wismer, F. Robinson and R. Renema
Omega – 3 enrichment of chicken: Understanding the process. ZUIDHOF – Further investigating into optimization of omega-3 enrichment of broiler meat continued. We learned that it takes longer to enrich breast meat than thigh meat to the 300 mg /100g threshold needed to use a product label indicating the meat as a source of omega3 poly-unsaturated fatty acid. Perez and Betti found that while the flax-based medium chain omega-3 fatty acid accumulated in the fat cells, the longer chain omega-3 fatty acids (like DHA) accumulated in the cell membranes Team: M. Betti, R. Renema, T. Perez, D. Korver and V. Carney
Understanding Omega-3 enrichment of chicken: Fatty acid profiles and stability BETTI – The PRC value-added team conducted research to establish the fatty acid profile and level of omega-3 poly-unsaturated fatty acid (n-3 PUFA) enrichment in fresh and cooked chicken meat. Antioxidant stability was provided through combinations of Vitamin E and Organic Selenium. The highest level of n-3 PUFA enrichment was
in raw thigh meat with a dietary treatment of Vitamin E and Selenium (1,429 mg LNA / 100g meat). While treatment did not affect overall fat content or level of long chain n-3 PUFAs, n-6:n-3 ratio changed between the raw and cooked state. This is important, as the health benefits of n-3 PUFAs can be dependent on the body’s ability to absorb them (n-3 PUFAs compete with the n-6 fatty acids for absorption). Team: T. Perez, R. Renema, M. Zuidhof, Y. Ren, and J. Wu
Stability of Omega-3 fatty acids in eggs ZUIDHOF – In a related study exploring the storage and cooking stability of omega-3 PUFAs in enriched eggs fortified with antioxidants. The higher concentration of unsaturated fatty acids in omega-3 PUFA enriched eggs is more susceptible to oxidative damage during storage and cooking, as well as potentially triggering breakdown of cholesterol into cholesterol oxidative products (COP). The C18:3 (LNA) and C18:2 (LA) concentrations were increased in eggs from the Selenium compared to the Control treatment, with no difference found for the Vitamin E or the Vitamin E + Selenium treatments. All of the antioxidant-fortified treatments raised the concentrations of the long-chain PUFA’s, C22:5 (EPA) and C22:6 (DHA) compared to eggs from the Control diet Team: Y. Ren, R. Renema, M. Betti, J. Wu and T. Perez
Extracting valuable health compounds from eggs WU -- Ovomucin, a viscous protein that was first isolated in 1898, contributes to the nature of egg white. In addition to its excellent gelling and emulsifying properties, ovomucin was reported to have antivirus, antitumor and cholesterol-lowering properties. A novel technology to extract high purity ovomucin (greater than 90%, compared with the purity of less than 70% using previous methods) has been developed at our laboratory. It is expected that ovomucin will have wide applications as functional food/nutraceutical ingredient and biomaterial. A Report of Invention based on this new technology was filed in March to initiate the protection of the intellectual property. Team: A. Dileep, N. Kav and V. Mazurak
F. Meat and Egg Products (cont.) QSAR-aided study of antihypertensive peptides from eggs
Handling stress and temperature stress affect meat quality
WU -- Bioactive peptides, small fragments from egg proteins, may have implications for a wide range of chronic diseases (e.g. cardiovascular diseases, cancer and diabetes). Using in silico digestion, we have generated over 20,000 kinds of peptides from egg proteins. The most potent antihypertensive peptides have been predicted and the study is currently underway to release specifically these peptides from egg proteins. In addition, our preliminary research indicated that intake egg products (boiled egg and fried egg products) could release antihypertensive peptides through the action of gastrointestinal enzymes. Hypertension, a disease affecting over 20% of population in North American, is one of the well-identified major risk factors for the development of heart disease.
RENEMA -- In a project nearing completion, this group examined the relationship of an acute handling stress or a longer-term temperature stress on meat quality in broilers between 28 and 56 wk of age. Drip loss was lowest in birds held in the cold treatment (2.0%) vs the heat and neutral treatments (2.3 % and 2.2%, respectively). One of the more important measures of meat quality is 15 min pH, which was strongly affected by the shackling stress treatment (10 seconds or 120 seconds handling on shackles). We are working on developing a ‘flap-test’ as a potential measure of stress response in broilers. Team: B. Schneider, M. Betti, M. Zuidhof and V. Carney
Team: M. Kaustav and S. Davidge
G. Bioeconomic Modeling Optimal broiler feeding programs If we feed too little protein, birds get fat. People eat this fat, with consequences on their health. If we feed higher protein diets to broilers, we can increase lean yield or the levels of healthier types of fat, and have a better impact on human health. We are continuing to evaluate the data set to find optimal industry solutions. Team: F. Hernandez, B. Schneider, R. Renema, D. Korver, M. Betti, V. Carney, and F. Robinson
The metabolic heat of the food you eat… a study of broiler heat stress ZUIDHOF – A pilot study was conducted to determine the suitability of wireless remote temperature sensors for early detection of disease. The following results are a bonus. The effect of nutrition and heat stress on core body temperature was investigated. Body temperatures were higher in birds fed a low compared to high energy diet (39.6C vs. 39.3C). Body temperature was significantly
different in all protein treatments, with higher and lower than recommended protein levels resulting in lower body temperature (39.4C vs. 39.4C vs. 39.7C, respectively). Heat stress conditions increased body temperature by 0.42C. The body temperature response to heat stress was affected differently depending on energy and protein in diet. Body temperatures of low energy birds increased 0.37C more than in birds fed higher energy. Body temperatures increased 0.60C in birds fed 100% of recommended protein, 0.37C in birds fed 115%, and 0.29C in birds fed 85% of recommended protein. These results demonstrate that nutrition affects body temperatures of broilers, and that nutrient levels in feed can modulate their response to heat stress. Team: R. Renema, D. Peters, J. Berezowski, F. Hernandez, and C. Annett
G. Bioeconomic Modeling (cont.) Environmental temperature affects hen body temperature and egg characteristics RENEMA -- Laying hens received surgically-implanted remote temperature sensors as part of a project determining their value in the early detection of disease. Frequent measurement of feed intake, body weight, and egg weight allowed us to determine hen efficiency down to the level of actual maintenance requirements adjusted for feed intake. After 2 wk at the same temperature, birds were moved to a warmer or cooler environment. Birds in the 28 C room had a 0.5 C higher core body temperature than the birds at 18C. Despite eating a similar amount of food, the warm room birds diverted fewer nutrients to keeping warm and ended up gaining 3 g more per day in BW than those in the cool room (who actually lost some weight). The shell quality of the warm
room birds was also slightly reduced. This suggests early signs of heat stress. The increased yolk size in warm room eggs demonstrates the availability of extra nutrients in this environment due to lower maintenance requirements. This study led to new insights on the relationship between feed intake and classification of a hen as efficient or not. Additionally, we were able to determine the direct impact of bird microclimate (through comparison of internal to cage-based temperature sensors) on hen temperature and efficiency. Team: C. Oort, A. Abiaka, M. Zuidhof, and A Pishnamazi
