This investigation was carried out to evaluate certain egg quality characteristics of ISA Brown laying hens and Japanese quails (Coturnix coturnix japonica) in relation to their age. One hundred forty-four brown-egg ISA Brown laying hens and one hundred female quails were used in the study. A total of 1,678 eggs of laying hens and 2,060 eggs of Japanese quails were used during the experiment. The eggs for technological values were collected during two consecutive days in a 4-week period when […]

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 […]
