[QUOTE="RVF, post: 529947, member: 7960"] I am taxing my memory on this one, but the research came out in the mid to late 1980's. The jist of the program was that the research station set up a breeding trial where they took a herd of Angus cattle and bred 1/3 for large size, 1/3 were randomly bred and stayed approximately the same size and 1/3 were bred for small size. In their environment, the small line was the most productive line and was later marketed as the Lowline Angus. I assume that the claims of more beef per acre would be based on the whole production system where the higher number of lowline cows per acre and probably higher conception rate, weaning rate would result in more calves and beef being marketed as fat cattle. If I remember correctly there was no difference in efficiency of the steers in the feedlot. It would go something like this: If your farm could support 100 cows weighing 1200 pounds producing 95 calves weighing 500 lb or 47500 lbs of calf every year, the same farm would support 150 cows weighing 800 lbs. These smaller cows then produced 144 calves weighting 333 lbs or 48000 lbs of calf every year, hence the claim to more beef per acre. Please do not take my example as what the results of the trial was. I am presenting what I remember the concept to be. I would also be interested in the link to the research so I do not have to trust my memory on stuff 20-25 years old. As others have stated, I think it will be a while before the lowline see use within the commercial beef production system since they do not fit our present finishing and packing industry. However, if you can develop a market where you sell all the calves as beef go for it. Just do not get bigger than your niche market. [/QUOTE]
