“…Birth weight increased as the age of dam increased and did not appear to decline with the older animals. This agrees with Lawson and Peters (1964), although Dawson, Phillips, and Black (1947) found that birth weight did not increase after the age of the dams reached six years. Male calves averaged 3.4lb heavier at birth than heifer calves in the current study.…”

A study of the effects of a high, in contrast with a very low, planc of nutrition prior to calving, on the performance of hill-country beef cows and their calves, is described. On 8 June 1964, 122 three-to eight-year-old pregnant Aberdeen Angus cows were allocated to two equal groups. Thereafter, one group was maintained on a high plane of nutrition and the other group on a low plane of nutrition for, on average, 90 and 83 days rcspectively, until calving. All cows were offered a high plane of nutrition after calving. Low plane cows lost on average 155 lb, and high plane cows 38 Ib, betwecn initial liveweight and post-partum. After calving low plane cows rapidly recovered in liveweight, and, by weaning five months later, had compensated for their previous livewcight loss. The number of calves present at weaning as a percentage of the number of cows at the start of the experiment was 93.4% and 75.4% for the high and low pre-calving treatments respectively. Low plane calves were 121b or 20% lighter than high plane calves at birth. The mean difference in calf liveweights between treatments was 36.4 lb at weaning.
