In order to evaluate digestible lysine levels on the performance and carcass traits of castrated male pigs from 60 to 100 days of age, 300 barrows with initial weight of 25.0±0.52 kg were allotted in a completely randomized block design with five treatments (0.65, 0.75, 0.85, 0.95, and 1.05% digestible lysine levels), five replicates, and 12 pigs per experimental unit. There was no effect of digestible lysine levels on average daily feed intake. The average daily gain increased and feed […]
