Carcass Composition and Skeletal Muscle Distribution in Broilers Produced under Different Nutritional Regimes-3. Male Broilers Showing Maximum Early Growth and Restricted Later Growth

In this study we investigated feeding methods which would lead to a high hind limb to wing muscle ratio in broilers. One group of male chicks was reared with a layer grower feed (LG, ME 11.92 MJ/kg, CP 170 g/kg) from 1 to 80 (LG80d) or 95 (LG95d) days of age. A further group of chicks was reared with a broiler starter feed (BS, ME 13.18 MJ/kg, CP 205 g/kg) from 1 to 21 days and then with a pre-layer feed (PL, ME 11.72 MJ/kg, CP 140 g/kg) up to 80 (BSPL80d) or 95 (BSPL95d) days. 2. LG80d (2490 g live weight) and BSPL80d (2648 g) birds did not attain sufficient body size (3 kg) to slaughter at 80 days.
