[QUOTE="HerefordSire, post: 618148, member: 4437"] [i]Theoretically.... ...having all big cows can be more efficient than having all small cows even if their weaning percentages are not the same. The reason is because of variances in individual metabolism. If you had a small cow weaning a high percentage relative to another small cow weaning the exact same high percentage, and you had to cull one, which one would it be? I would cull the one that ate the most, not the one that weighed the least. How am I going to know which one that is? Another way of looking at it...say I have 100 easy keepers all weaned the exact same percentage....which ones do I cull? Do I cull the ones that weigh the most? No! I cull the ones that eat the most. I can't cull the ones that weigh the most because the metabolism may be lower than one that weighs less, maybe due to the age or maturity or breed.[/i] [/QUOTE]
