'One should never loose sight of the fact that the ability to grow rapidly to desirable market weight with an acceptable degree of finish, next to being born alive, is THE most important trait of any beef animal' Jack Cooper, 1960


HISTORY OF THE LINE ONE PROGRAM

1934 - 2019

With a simple objective to increase profit for cattle breeders, the Line One breeding program was established in 1934 by the United States Department of Agriculture (USDA). To this day the project remains located at the Ft Keogh Research Centre, Miles City, Montana. Whilst the practice of line breeding has been implemented throughout history never before had a structure program been undertaken to deliver an economic objective. To establish the program the finest genetics of the era were selected as foundation stock. These included two sires - Advance Domino 20 & Advance Domino 54 - both progeny of Advance Domino 13 . The sires were purchased from the highly regarded herd of Fred DeBerard. 50 Hereford females were purchased from the herd of George Miles, a highly regarded maternal herd. Daughters of each sire were then mated to their paternal half-siblings and the Line One program progressed. Since 1934 Line One Hereford cattle have been maintained by USDA at Miles City descending solely from this foundation. Line One illustrates a successful line breeding program in which a high degree of relationship (>40%) to the founding sire has been maintained for generations. Without line breeding, the relationship to an ancestor generations ago is far less than 1%. Careful attention has been kept to avoid breeding close relatives. Nearly all academic and commercial tests that assess production characteristics of individual bulls can be traced to research undertaken on the Line One program. Data from Line One also contributes to the first estimates of heritability and genetic correlation for beef cattle in turn founding the Beef Improvement Federation. While 85 years may have passed the Line One program remains a cornerstone in the beef cattle industry. It has aided the progression of the global beef industry and achieved beyond any doubt its objective of increasing profit to breeders using Line One genetics. Line One Herefords - 85 Years in the making.


KEY OUTCOMES OF LINE ONE

MAXIMUM ULTIMATE HETEROSIS COW HERD During the past 85 Years of closed line breeding the genetic composition of the greater Hereford genetics population has migrated away from the Line One population. This diversity is now sufficient to generate Heterosis, or hybrid vigour, when joining Hereford cows to Line One bulls.

For generation after generation the Line One herd has maintained a strict focus on selecting for traits that maximise profit. The program is conducted in a purely commercial environment to prove the animals ability & verified through unequalled performance testing.

Heterosis is widely recognised as a primary tool to drive herd profit and as breed based beef branding continues the impact of Line One is unmistakeable.

The intensity of the selecting for profit generating traits has given rise to the unrivalled maternal strength of Line One cows. Line One cows consistently are more fertile, offer genuine calving ease, produce higher weaning weights, and maintain greater longevity than any other genetics. Line One bred cows are renowned for their survivability and production efficiency in commercial settings. 85 Years of selection refinement produces cattle that are profitable, predictable & uniform.

The benefit of Line One genetics also allows commercial breeders utilising a 3 way crossbreeding program to utilise only 2 breeds therefore maintaining market demand for their progeny whilst benefitting from all that Heterosis offers a profit driven program. The results of Line One in maximising maternal heterosis are renowned. This makes Line One the choice of more Cattlemen globally.

These attributes are critical to a profitable beef production and sought after by leading cattleman globally.


KEY OUTCOMES OF LINE ONE

GREATER PROFIT Long term focus on higher yearling weights has proven Line One genetics as the most profitable in the beef industry. In conducting research a strong correlation between the following has been established; ü  Higher weaning weights (achieve earlier sale weights);

ü Increased body fat (increased survivability and marbling correlated); ü  Earlier maturity pattern (increased fertility and reproduction); ü  Increased lifetime maternal performance (maximum longevity).


BENEFITS OF LINE ONE

INCREASED PROFIT 85 Years focussed on increasing yearling weights. More kilograms at a young age is a proven key driver to higher profitability throughout the industry whilst building maternal quality.

MAXIMUM HETEROSIS As the genetic composition of non Line One cattle (both Hereford and other breeds) has diverged Line One genetics have maximised Hybrid Vigour. Studies have proven Heterosis delivers; ü  ü  ü  ü 

4.4% Increased Calving Rate; 3.8% Higher Yearling Weights; 16% Higher Longevity in Breeding Cows; 25% Higher Kilograms of Beef produced per cow.

HIGHER MATERNAL VALUE Focussing on increased yearling weight has developed lines of breeding cows that are renowned for their maternal ability. Preferencing strong calves at young ages requires a greater contribution by the dam. Only cows that are capable of reproducing and rearing calves under purely commercial environments have survived 85 years of rigorous selection pressure.

INCREASED CARCASE VALUE Intramuscular Fat is exactly that, ‘fat’. The correlation between higher body fat and IMF stands to reason. Higher body fat and survivability has remained a focus of Line One. Cows with higher fats mature earlier and produce heavier calf weights at earlier ages. In an industry that recognises IMF as THE most determining factor of carcase value focus Line One genetics offer great application.

PREDICTABILITY, CONSISTENCY & TYPE The aim of Line Breeding is to maximise the prevalence of desirable genetic traits. Line One cattle today contain a breeding co-efficient of 24-36% meaning the progeny of Line One bulls are consistent in performance and type beyond all others. Increased consistency attracts buyers and allows Producers to market larger lines of cattle therefore maximising demand for Line One sired calves.

ADAPTABILITY Line One genetics have proven their ability to adapt and perform in all climates across the globe.

COMMERCIAL FOCUS The Ft Keogh Research Centre operates on a commercial production systems. Cows are selected on performance without pamper, capturing only genuine profit driving genetics – not show winners!

GLOBAL DEMAND FOR LINE ONE Today a select group of breeding programs maintain pure Line One herds. These herds have been built from only Line One genetics without intrusion. The cattle from these programs are sought after and in demand from both the commercial and seedstock industry. This year more cows in the USA will be bred to a Hereford bull then ever before and Line One genetics have driven this change. In March each year Holden & Cooper herds conduct their Annual Production Sales. Now in their 53rd year Cattleman from across the world return to source the finest Hereford genetics. The results of these sales consistently outperform all other programs as Cattleman of both straight and cross breeding programs compete for herd building genetics.
