The intensive rearing of lambs 1. Some factors affecting performance in the liquid feeding period

Investigations into possible ways of rearing artificially the lambs surplus to the ewe's capacity are described and the results discussed. 2. A ewe-milk replacer with a high fat content was used from 2 days of age until weaning at 11.4 kg live weight. Two levels of milk feeding, restricted and ad libitum, were given in the second year. Significant differences were observed in live weight gain per day, milk consumption per kg live weight gain and solid food intake prior to weaning. Live weight gain and solid food intake in the period immediately after weaning also differed markedly. Sex and birth weight had little effect on performance. 3. Food costs were lower on the restricted level of milk feeding than on the ad libitum level.
