[Metabolism and hematology studies of intensively raised fattened lambs under various feeding and management conditions. 3. The effect of weaning age under various management conditions on the blood picture, serum mineral and bilirubin concentration and vitamin A concentration in the liver].

Calcium, phosphorus, magnesium and bilirubin, blood picture and liver vitamin A were studied in six groups of lambs weaned at various ages and fattened under four types of management, in comparison with a control group. Results are shown in graphs and tables, with a comparison with conventionally fattened lambs. Age at weaning had no demonstrable effect on the parameters investigated.
