A.S. Series 71-19
Twenty-eight registered Angus and Hereford cows calved in September, 1970. The cows calved on pasture and remained on pasture until late November. From November 10 to December 28 the cows were bred for 1971 and started on a self-fed diet. The remaining 14, or one-half of the calves, were allowed to continue nursing the cows, but the calves also had access to calf creep with the same diet used for the weaned calves. At the start of the experiment the calves were randomly divided by sex, breed and age. At this time, December 30, 1970, the average age of all calves was 106 days and they averaged 218 lb. in weight.
