The objective of the present study was to evaluate the effect of dietary crude protein (CP) levels and the use of a nutritive solution via drinking water on the performance of pre-starter broilers. A total of 1,224 male Avian Farm chicks, from one to 40 days of age were used. Birds were distributed in a completely randomized experimental design with a 3 × 2 × 2 factorial arrangement, consisting of three initial body weights (low: 41 g, standard: 45 g […]

Two experiments were carried out to determine the total lysine requirement of purebred Landrace swine, males and females, from 15 to 30 kg live weights. Fifty females and fifty males were used in a randomized complete block design, with five treatments, five replications and two animals per experimental unit, in the experiments I and II, respectively. The treatments consisted of a basal diet, supplemented with five levels of L-lysine.HCL, resulting in diets with .85, .95, 1.05, 1.15, 1.25% of total […]
