Efficiency of feed nitrogen utilization in young pigs given a diet containing varying amounts of available methionine


, : Efficiency of feed nitrogen utilization in young pigs given a diet containing varying amounts of available methionine. Sel' skokhozyaistvennaya Biologiya (4): 72-79

Addition of available methionine to the diets given to young pigs 25 to 42, 43 to 60, 61 to 106 and 107 to 126 days old to bring methionine level to optimum amounts of 2.99. 2.46, 2.07 and 2.22 g/kg diet, respectively, increased the efficiency of protein utilization by 30 to 60%, decreasing with age, decreased feed cost of weight gain by 23 to 5% and increased average daily gain in the younger pigs.
