Part 1.- Effect of rearing intensity and age at calving on calving performance.- Pre-calving management and feeding of the beef cow in relation to calving problems and viability of the calf.- Problems associated with the calving and neonatal period in beef cattle.- Discussion.- Nutrition and Management of the Dam in Relation to Calving Problems. Part 2.- Effect of plane of nutrition during late pregnancy on the incidence of calving problems in beef cows and heifers.- The influence of pre-partal feeding on energy metabolism in early lactation.- The influence of pre-calving feeding and management of the cow on ease of calving and calf viability.- Clinical aspects of the nutritional status of the dam and parturition.- Discussion.- Status, Nutrition and Management of the Newborn Calf. Part 1.- Conclusions from the EEC seminar on perinatal ill health in calves.- Immune mechanisms in the newborn calf.- The effect of different methods of feeding colostrum on calf blood serum immuno globulin levels.- Discussion.- Status, Nutrition and Management of the Newborn Calf.
