The aim of this study was to determine the effect of velvet bean (Mucuna pruriens) meal as a partial substitute for soybean cake on the productive performance of broiler chickens in the finishing phase. The study included 336 21-day-old Cobb chickens in four treatments with three replications: T0=0%, T1=5%, T2=10%, and T3=15% soybean cake replacement with velvet bean. The feed consumption of T2 and T3 chicks was significantly lower than in the control group (p<0.05), but similar to T1. Feed conversion was similar between the three velvet bean treatments, but T2 presented a better conversion than T0 (p<0.05). Carcass percent and body weight gain were similar among treatments. The highest economic returns were obtained in T2 (S/. 1.75 per chicken) and T0 (S/. 1.73), closely followed by the other treatments. It is concluded that 10% velvet bean meal can be used in the feed ration with...

The aim of this study was to evaluate the effect of vitamin C supplementation in mid-laying Japanese quail on productive performance and egg quality. Eighty quails of 23 weeks of age initiating the second third of laying were used. The birds were housed in 20 cages (four birds per cage) and distributed in a completely randomized design with four levels of inclusion of vitamin C in the basal diet: 0, 100, 200 and 300 mg of vitamin C per 100 kg of feed. As productive performance, the feed intake (g/bird/day), laying percentage and feed conversion were determined. Additionally, the weight, height and length of the egg, the height and weight of the yolk and the albumin, and shell thickness were measured as egg quality variables. Vitamin C supplementation at increasing levels in the diet of quails had no effect on productive performance and egg quality, except on shell thickness (p<0.05).
