The objective of this work was to determine inclusion levels of sodium chloride (NaCl) in diets for male and female Colonial strain birds in the starter (from one to 28 days of age), growing (from 28 to 56 days of age) and finisher (from 56 to 84 days of age) phases reared in free-range system. In each trial, 480 birds at age corresponding to the rearing phase were housed in 24 experimental units containing areas of shelter and pasture. The […]

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 […]
