| Two experiments were conducted in order to evaluate the effects of different dietary amino acid and calcium profiles on the bone characteristics of two chicken strains (Avian Farms and Cobb) during the starter phase. At the end of each experiment, 2 chickens of each replicate were sacrificed and their tibiae were collected for analysis of following bone characteristics: bone measurements (weight, length and thickness of the compact and spongy layers) and bone density (bone densitometry). A total of 540 birds were used in each experiment, divided into fully randomized blocks with a 3 x 2 factorial schemes, i. e., 3 amino acid profiles (methionine, lysine and threonine ­ 100%, 125% and 150% of NRC recommendations, 1994) and 2 calcium levels (75% and... |
