A.S. Series 72-27
Twenty-five registered Angus, Hereford and Shorthorn cows calved in September, 1971. The cows calved on pasture and remained on pasture until early November. From November 12 to December 29, the cows were bred for 1972 fall calves. On December 29, 1971, one-half of the calves were weaned and started on a self-fed ration. The remaining one-half of the calves were allowed to continue nursing the cows, but the calves also had access to a calf creep feeder containing the same ration 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 29, 1971, the average age of all calves was 114 days and they averaged 257 lb. in weight.
