DESCRIPTIONCrossbreeding program designed for northern pasture operations.
- 1. Arizona? Iowa? Upper Michigan? Probably Not!
2. 1. Utilize beneficial Highland traits as efficiently as possible. 2. Realize that we live in an Angus world. 3. Cow 4. 1. Longevity 2. Low maintenance costs 3. Efficient grazer 4. Ability to browse 5. Calving ease 6. Smaller frame 5. Because of their longevity, Highlands are uniquely suited for terminal crossing. 6. 1. Maximize hybrid vigor 2. Specialized sires and dams 3. Lower bull turnover rate 4. Easier genetic choices 5. Consistency 7. 1. Must purchase replacement females. 2. Or have multiple levels of production on the same farm. 8. 1. More productive due to hybrid vigor 2. Hybrid vigor maximized when pure British breed crossed with pure Continental breed 3. More longevity 9. The increased vigor or general health, resistance to disease, and other superior qualities that are often manifested in hybrid organisms, especially plants and animals. 10. Auroch Cattle Extinct 1627 All cattle descendants of Aurochs 11. Increased separation of breeds of cattle by distance, natural barriers and selection pressure increases hybrid vigor when mated. 12. The increased vigor or general health, resistance to disease, and other superior qualities that are often manifested in hybrid organisms, especially plants and animals. 13. 1. Have more lbs of carcass/steer. 2. Have more lbs of carcass/acre. 14. We need to think of cattle as feedlot type and pasture type 15. Increase cattle weight means increased pasture damage. Yields may be reduced as soon as 3 days of pasturing. 16. 1. Continental breed. 2. High weaning weight breed. 3. Small frame size. 4. Polled 5. Popular breed for crossing with Angus. 17. Astro - Gelbvieh Bull 18. Simmental 1353 pounds Hereford 1348 pounds Angus 1342 pounds Charolais 1339 pounds Limousin 1330 pounds Gelbvieh 1282 pounds 19. Gelbvieh produced the highest weaning weight per cow exposed to breeding at Clay Center 20. Gelbvieh cattle are a lean breed. Of all the breeds studied at Clay Center, they had the largest ribeye muscle area per 100 kg. Thus they have a high cutout yield. 21. Balancer Bull = Gelbvieh x Angus 22. Feedlot Angus, Hereford, Simmental, Etc. Show Cattle Club Bull Kobe/niche market - Wagyu Grass Lowline Angus 23. Lowline Cattle History The Australian Lowline cattle came from a cattle research project conduced by the New South Wales Department of Agriculture located in Trangie, Australia. The 30-year project was started in the early 1970s with the ultimate goal being to produce more beef per acre. 24.

Beef cows with a hair coat just one inch thicker than average requires 20% to 25% less digestible feed intake to maintain body weight in cold weather. Montana State University 29. Gelvieh x Highland Steer Sandhill Pines Farm 30. The U.S. beef cow herd has decreased 12 of the last 14 years, dropping from a cyclical peak of 35.3 million head in 1996 to the January 2010 level of 31.3 million head. This represents the smallest beef cow herd since 1963. Because of drought, another 600,000 decline is expected in 2012.
