There has been a great deal of interest in recent years in the relationship between cow size and efficiency. Researchers have determined that maintenance feed requirements are greater for large cows. This finding has furthered the belief that efficiency through weaning is highly dependent upon cow size. It must be pointed out, however, that other studies have generally shown heavier cows produce heavier calves at weaning. It is the purpose of this report to examine feed requirements to produce a unit of weaning weight with regard to size and breed of cows.
