“…This is particularly so for twinsuckling cows that are capable of producing average milk yields in excess of 18 kg/day on estimated energy intakes of between 80 to 125 MJ ME per day (Khan, Topps and Broadbent, 1986;Topps, Islam, Broadbent and Paterson, 1989). Therefore, the strategy of having autumn-calving cows in reasonably good body condition at calving may be sound.…”

1994). The effect of pre-and post-partum energy and protein supply on the performance of single-and twin-suckling beef cows and their calves. AbstractChanges in live weight, body condition, milk production and composition xvere monitored for single-and twinsuckling cows in two experiments. In experiment 1, all cows were managed for 3 months before calving to achieve condition scores at calving 2-1 (low) and 3-1 (moderate). Subsequently, these animals were placed on a fixed level of energy intake (80 M] metabolizable energy (ME) per day) for 16 weeks. Post-partum diets contained differing amounts of digestible undegradable protein (DUP), but similar amounts of effective rumen degradable protein (ERDP). In experiment 2, single-and twin-suckling cows were fed to achieve a condition score at calving of around 2-75. These animals were subsequently placed on two levels of energy intake (80 MJ and 130 MJ ME per day) during the first 16 weeks of lactation. The diets providing these energy intakes also contained differing amounts of DUP. Neither the level of DUP in the diet nor the level of feeding significantly altered the digestibility of the dry matter or organic matter in the dry matter of the experimental diets. Body condition at calving had little effect on daily milk yield (9-5 kg) and composition (33-5 g/kg fat; 30-0 g/kg protein) in experiment 1. Cows with higher body condition scores at calving lost 13-5 kg more live weight and 0-26 units more body condition (P < 0-05) during the 1st month post partum but remained in better condition throughout the trial period than cows with lower body condition scores. Cows on 130 M] ME per day produced higher (P < 0-001) daily yields of milk, milk fat and protein (+2-0 kg; +151 g; +85 g) and lost 57 kg less live weight and 0-52 units less body condition (P < 0-001) than cows on 80 MJ ME per day. Elevated dietary levels of DUP promoted (P < 0-05) daily milk yields (by 1 -25 kg) and reduced live-weight and body condition-score loss during the 1st month post partum in both experiments. Twin-suckling coivs produced the highest average daily yields of milk throughout the 16-week trial period in both experiments but yields were not significantly higher after early lactation in experiment 1. Cow body condition score at calving and the level of DUP in the post-partum diet of cows had no effect on the post-partum performance of calves. Twin calves had slower growth rates (P < 0-001) than single calves (0-65 and 1-07 kg/day respectively) in experiment 1. However, twin calves sucking cows on 130 MJ ME per day in experiment 2 grew similarly to single sucking calves from week 8 of lactation (0-8 kg/day).

“…Maternal dietary protein restriction during pregnancy can affect fetal growth through lack of supply of certain amino acids to the fetal tissues and may reduce the birth weight of offspring (Dunn, 1980;Robinson, 1983Robinson, , 1990). During late pregnancy in cows, the protein and energy requirements are 1-5 times the maintenance needs and any deficiency may lead to restricted growth (Wright et al 1986;Topps et al 1989). Additional dietary protein intake to the extent of 0 .…”
