The accumulative effects of different levels of annual energy intake over the first two parities on four breeds of beef cow (small size and low milk potential, Aberdeen Angus; small size and high milk potential, Welsh Black; large size and low milk potential, Charolais; and large size and high milk potential, Simmental) were assessed for various production traits and calf performance. Heifers were allocated to each of two levels of annual energy intake relative to metabolic body weight (M0·75) (mean daily intakes equivalent to 705 and 820 kj M0·75) and for the next 2 years these animals (10 per breed) were continuously housed and given diets designed to represent energy intakes while grazing during the summer and conserved forage feeding during the winter. Changes in live weight and body composition were measured throughout both years and milk yield, milk composition and calf performance during both lactations.
Animals from each of the four breeds gained weight but lost body condition during their first two parities in a manner that was dependent on their annual level of dietary energy intake. Welsh Black cows grew more than Aberdeen Angus cows and Charolais cows more than Simmental cows so that, by weaning during the second parity, the rank order of live weights between breeds was Charolais > Simmental > Welsh Black > Aberdeen Angus. Welsh Black and Simmental cows produced higher yields of milk (7·9 and 8·7 kg respectively) than Aberdeen Angus and Charolais cows (6·5 and 5·7 kg respectively; P < 0·001). Calves from the two large breeds grew more quickly than those from the two small breeds (1·13 v. 0·99 kg/day; P < 0·01) and calf performance was influenced by milk consumption. Biological efficiency, defined as weight of calf at weaning per GJ metabolizable energy (ME) on an annual basis, increased as annual energy intake decreased and tended to be higher for large breeds on 33 GJ ME per year than for small breeds on the same level of annual energy intake (7·19 v. 6·75). The complex means by which the different breed types interacted with their nutritional environment is discussed.
