A total of 1,225 one-day old chicks were obtained from a commercial hatchery and were grown over a 34-days period (five weeks). At 34 days of age all birds were weighed and redistributed into a completely randomized design to perform the following treatments: control (0% feed restriction), 10, 20, 30 or 40% feed restriction. The amount of feed given to animals was adjusted daily according to the previous day's intake of the control treatment. At 42 days, birds were weighed and two birds per pen were slaughtered, one to evaluate carcass yield and cuts and the other for body composition analysis. Weight gain and feed intake were decreased linearly (p<0.05) according to increasing levels of restriction, while the feed:gain ratio showed a quadratic effect (p<0.05). The ...
