Four hundred and eighty Ross broiler male, with initial weight of 43 ± 0.2 g, from 1 to 21 days of age, were allotted to an experimental design in 2 x 4 factorial arrangement, two environments (high temperature and thermal comfort) and four levels of total lysine (1.1, 1.2, 1.3 and 1.4%) with six replicates and ten birds/experimental unity. Feed intake (FI) and weight gain (WG) were higher in the thermoneutral environment, while the feed: gain ratio (F/G) and the […]
