2022 Private Sale List We’ve seen change over the last period – 

We’ve decided to sell out of our Droughtmaster Stud, with them returning to Queensland. We have kept a handful to keep a small line to breed a Droughtmaster based composite – our kind of Ultra Black/Red.



Since dropping JBAS8 status, we have had the opportunity to buy smaller lines of our clients’ weaners and utilize our little feedlot to take them to market. This gives us the opportunity to see how they perform and so far, we are impressed. If you do have weaners available, please contact us?



With the new land producing (rehabilitated a vineyard), we are developing a commercial composite herd. We have been impressed with the Leachman Stabilizer program and can see a future. We will continue keeping the higher $Profit bulls for private sale



Selling yearling bulls has been a success, we believe this has benefits for all concerned, these young bulls settle in easier, are eager to serve a small group, are genetics a generation in advance, are not over fed (no grain) and easier to transport.

Although we are only selling a reduced number of bulls, we feel they are quality and have the proof to back their genetic capabilities. Any tool that can help produce a profit boost to stud or commercial herds is a must.

South Devon – We offer 10 bulls, 8 red and 2 black. Have a good look over these bulls, they are all high $Profit. Sons of Davelle Cool Beau N51, Davelle Durango Nant M19, BC Progress 315U, Hawkley SAS Intrepid and EBS Elker1121 642A are represented.

Composites – We offer 2 black and 1 red composite bulls. They are sons of Paringa Black Stabilizer N699, who has been a very safe bull used over South Devon heifers. From 2023 the numbers and diversity of sires will be represented.

We look forward to talking to you to discuss your needs for a bull. Please don’t hesitate in contacting us and you are quite welcome to visit and inspect.

We thank existing clients for your valued support and look forward to meeting new ones.

Regards David and Rochelle Leese *Stop Press* Early 2024 we are planning a Female Sale upwards of 40 will be available. We will keep you informed.

Our Objectives – We feel it is important to share our Objectives, as these should work into yours.

Our first and foremost objective is to grow grass. To utilise we need good efficient converters, we have found this within the South Devon and our composites, they are very efficient beef cattle.

The beef cattle we breed for will be – an easy doing, good tempered, fertile animal that shows a lot of capacity – both in the meat it houses and throughout the body, length, medium frame and the willingness to perform under differing conditions.

Females are the backbone of the herd – they need to have a live calf every year, grow that calf quickly so it yields well and is efficient, adding profitability. We believe if you breed for the perfect female, males follow.

We submit data to $Profit to find these curve bending animals with strong carcass traits. We believe in performance recoding as a tool available. We use all tools to help find animals that meet beef breeders’ objectives – subjective and objective.

Fertility drives everything!! American beef economists claim fertility and maternal traits are 5 to 10 times more important than any other traits.

Davelle Balanced Breeding targets for low birth weights, good growth and excellent carcass.

Davelle has a package that is meeting the objectives of the beef industry backed by reliable data.

We will always select animals on functional type and eye appeal first. Then we look to Indexes and individual ABE’s. The ABE’s pattern we are striving looks like this – Birth Weight 200 Day/Weaning Weight 400 Day/Yearling Weight 600 Day Weight Mature Cow Milk Carcass Traits

Below average – No bulls are kept over 45kgs BW. Average Average Average– flattening out growth so breeding females don’t get to big Average to slightly below average Average – we need to be careful if the season dries up.

Above Average - all traits to be strongly positive

We want females to peak their growth at around 3 years old. We want animals to put on as much weight as possible with desired carcass traits and then without breeding cows getting too big – efficiency.

Using figures can be fraught with danger. A good understanding is needed. The biggest number is not always the most desirable and sometimes average is best. The $Profit index helps put all of this into context, the larger the number the more profit.

Fertility - Low Birth Weights – Good Growth – Excellent Carcass www.davelle.com.au

Black South Devon We have pursued Black South Devon’s importing semen from the USA. Breeders in the US have done all of the hard work upgrading to pure. The US South Devon is very different to the British. We like the US type for their moderation but no compromise on carcass.

Black South Devons are complimentary to British, Euro and Bos Indicus breeds. Remember the “Free Lunch” – hybrid vigor.

A Black South Devon bull over an Angus cow is a great cross as proven in the US –  black coat and British look maintained  increased weight  increased EMA  increased yield  IMF maintained  Increased Profit We feel they offer a tremendous opportunity to the beef producer. The Black South Devon is an alternate “Polled Black British” breed. As a crossbreeding option, they will be ideal as an alternate Black sire for hybrid vigor, F1 females are maternal machines.

Using Yearling Bulls The Benefits of buying yearling versus 2 year old –      

Yearling bulls are generally aged 12-15 months of age Faster genetic gain - source the latest and the best genetics 6 - 12 months earlier. The benefits of using new genetics earlier means getting more generations over a given period of time, which accumulates.

Better value for customers, they are more affordable to buy.

Will adapt to your environment quicker as big heavy bulls can crash and lose a lot of weight, making it harder to recover post joining.

No need to buy a big fat bull to get good genetics - what you see is not always what you get, check out their performance data.

You will be surprised what these young bulls can do!

Bull Health Program –      

All bulls have had their health treatments.

They have been running in 1 large group When you get them home, give them a few weeks to acclimatise to their new environment. Keep an eye on them if they are put in with older bulls Yearlings can handle between 25-40 females at one time, but the bigger the cows, smaller the group per bull Bulls can lose some weight after joining but recover to normal weight in time Keep an eye on the bulls during joining, and don't hesitate to call us with questions

$PROFIT

TM

We have decided not to continue with BreedPlan due to the low participation of South Devon breeders. Since our participation, BreedPlan has helped us design cattle to meet the market, focusing on many traits that are not easily accounted for such as intra muscular fat (IMF) and eye muscle area (EMA). Using the $Profit analysis will continue our pursuit in breeding the best beef cattle possible.

What is $Profit?

The $Profit Index tells you which bull calves make you the most profit, from birth to slaughter if you retain ownership and keep replacements. It includes the cow traits, fertility, growth, carcase and feed intake.

What does the single number, $Profit, do for me? $Profit helps you compare what different bulls are worth so you can easily find the best bull to improve your herd. Put simply, it does the selection work for you. Instead of working out which of the 20+ ABEs are most helpful to your herd, $Profit does the analysis for you, and sums it up in one figure.

Profit Explained Are all small cows really efficient? There seems to be a big disconnect in today’s beef industry. On sale day we want heavy, high quality steers to pay the bills. The rest of the time we want efficient cows to keep our costs as low as possible. Simply selecting for smaller cows with no regard for feed efficiency is not the answer.

Likewise, selecting for shear growth with disregard for cost is just as poor of a strategy. The best way to make your cowherd truly efficient, and your calf crop earn more, is to use $Profit ™ ABE (Across Breed EBVs) ™.

This is the only index in the industry that works on both sides of the ledger (production and cost). Cows that work! Steers that pay!

How $Profit works: $Profit assumes that the average commercial bull will have 100 progeny over its lifetime. The model assumes that you keep 30% of your heifers as replacements and that you retain ownership on the remainder of the calves through finishing and sell on a grid. We realize that many don’t retain ownership, but doesn’t it make the most sense to select from birth all the way to slaughter?

Our simulation model then factors in all of the effects on both income and expense to come up with a net profit figure for each bull. $Profit allows you to compare any two bulls and calculate the difference in profit that they are expected to generate in your herd. Let’s compare a $10,000 $Profit bull to $6,000 $Profit bull (the average 2008 born Angus bull). The predicted difference between the bulls is $4,000 or about $40 per calf. $Profit works for us and it will work for you too.

Fertility - Low Birth Weights – Good Growth – Excellent Carcass www.davelle.com.au

What traits are included in $Profit: $Profit includes nearly every trait that impacts profitability. The effect of most traits on profit is fairly simple to understand. Here is the list of what is included and its effect: Revenue Traits Calving Ease = more live calves Weaning and Yearling weights = more growth & weight for age Fertility (days to conception) = Earlier conceptions post calving and earlier puberty in heifers Carcass weight = Heavier carcase weights Marbling = better meat quality and value Ribeye Area = value as impacts yield grade % Retail Product = more yield is more saleable beef Cost Traits Cow mature size = in general bigger eats more Cow intake = more intake costs more Feedlot feed efficiency = cost of gain Some traits are not so easily characterized for $Profit. Milk, for example, is a good thing until you get too much. When over +25, milk ABE has a more negative effect on fertility than it has a positive effect on weaning weight. There are a few traits not yet included in $Profit: longevity, structure, and disposition. These traits are important but difficult to express in dollars. $Profit is the largest breeder owned data base in the industry with over 1,400,000 records - “from herds in the USA, UK, New Zealand and Australia” $PROFIT Financial index allows you to HAVE IT ALL!

$Profit Across Breed EBVs Dare to compare: You cannot afford to make mistakes in your breeding program! Choosing to use sires with incomplete or low value data can unknowingly make your herd less profitable – same work, same cost, poor results - unacceptable. $Profit ABEs (Across Breed EBVs) are the most reliable and comprehensive EBVs in the industry. They are backed by a large (over a million), long-standing (over 30 years), multi-breed (over 15 breeds) database. Using this system assures you of making sound breeding decisions with minimal risk of failure.

Davelle Composites - SDX 23% More!! Who can ignore to benefits of cross breeding to add profit.

We’ll use the South Devon female as the base and add other breeds, Stabilizers and crosses to compliment.

Stabilizer The Stabilizer breed is a multi-breed composite developed by Leachman Cattle Company. The breed is based on research done by the United States Department of Agriculture (USDA) at their Animal Research Service (ARS) at the Meat Animal Research Centre (MARC), at Clay Centre, Nebraska.

The Stabilizer breed is a blend of British and Continental inputs including: Angus, Red Angus, Simmental, Gelbvieh and South Devon. The Breed combines the fleshing ability, marbling, and moderate size of the British breeds with the muscle, milk, and growth of the Continental breeds. As a four breed composite, the Stabilizer retains 75% of the F1 hybrid vigour and thus allows producers to crossbreed with simplicity.

The MARC (Meat Animal Research Centre) started a project in 1973 called the Germ Plasm Utilization (GPU) project. Their research showed several advantages that come from crossbreeding. Most importantly they showed that hybrid vigour has a large impact on beef cattle productivity. The research demonstrated an 8% improvement in weaning weight when a purebred cow is mated to a bull of a different breed. The research also showed that crossbred cows are far more productive than purebred cows. The benefits came in multiple areas including more milk production, better body condition, faster re-breeding, and a longer productive lifetime. In total, the crossbred cows weaned 23% more weight than did purebred cows.

Historically, crossbreeding requires the use of complicated mating systems to keep the hybrid vigour effect.

Scientists designed rotational systems using three breeds. However, such systems were too complicated.

Furthermore, they resulted in wide swings in breed composition, and prevented breeders from having a uniform, well adapted herd. As an alternative, the researchers at MARC developed multi-breed composites.

Their study confirmed that such composite breeds retain hybrid vigour in proportion to the number of breeds used - using more breeds generates more retention of hybrid vigour. The Stabilizer (Marc II composite), with four breeds, retains 75% of the F1 hybrid vigour. Thus, breeders can breed composite bulls to composite females and keep most of the available hybrid vigour without the complexity and loss of uniformity associated with crossbreeding.
