Nutritional plans of digestible lysine for growing-finishing gilts

This experiment was conducted to evaluate nutritional plans of digestible lysine (DLys) for growing-finishing gilts. Eighty gilts with 63 days of age and an initial weight of 24.2±1.52 kg were distributed in a completely randomized block design, with five nutritional plans of DLys (9-8-7, 10-9-8, 11-10-9, 12-11-10, and 13-12-11 g/kg, from 63 to 103, 104 to 133, and 134 to 153 days of age, respectively) and eight replicates. Pigs were housed in pairs and fed their respective diets ad libitum throughout the experimental period (90 days). To monitor the animal development along the experiment at...
