ABSTRACT The purpose of this study was to determine if in ovo feeding with 25(OH)D3 could influence the incubation parameters of bone mineral composition, mineral density, and bone breaking strength in post-hatch broilers. Fertile eggs from Cobb® broiler breeders were either non-injected or injected with 0, 1.2, 2.4, or 3.6 μg of 25(OH)D3/100 μL olive oil at eight days of incubation. The data were subjected to variance analysis using the General Linear Model procedure (GLM) of SAS®. There was a […]

This study was carried out to evaluate the parameters related to hatchability of fertile eggs of Japanese quails. The eggs were stored for three periods (0, 72, and 144 hours), and incubated at two humidity (55 and 65%) and two temperatures (36.5 and 37.5°C) levels. A complete randomized design with a 3 x 2 x 2 (storage period x humidity x temperature) factorial arrangement was used. Evaluations were performed at 276, 324, 362, and 420 hours of incubation and at […]
