This experiment was carried out to compare the productive performance of commercial laying hens after being under different methods of induced molting. Ninety-six Hy-Line white laying hens, 85 weeks of age were allotted to a randomized block design with four treatments. The treatments were: T1 – the conventional method consisted of feed withdrawal during the 12 first days of the experiment; T2 – diet of high-zinc content; T3 – low-energy diet, fed limited daily portions (45 g per hen per […]
