The objective of this study was to analyze the behavior of three genetic groups of confined goats by image monitoring using nine unneutered goats of the Azul, Graúna and Moxotó genotypes. The experimental design was completely randomized, in a 3 × 3 factorial arrangement (genetic groups × periods – morning, afternoon and night), with three replications. Animals were monitored by video cameras placed at the ceiling of each stall for 10 days. There were interaction factors in the frequency of […]

The objective of this study was to determine the best sodium nutritional levels for Italian quails in the phase from 1 to 49 days of age. Three hundred and eight-four quails at one day of age were distributed in a completely randomized experimental design with six diets with 0.07; 0.12; 0.17; 0.22; 0.27 and 0.32% sodium, evaluated with eight replicates with eight birds per experimental unit. Levels of sodium, which were better at 0.257%, 0.216%, 0.207% and 0.191%, had a […]
