Resumo: Two experiments were carried out aiming at evaluating the effects of different dietary amino acid and calcium profiles on bone characteristics of two chicken strains (Avian Farms and Cobb) from 42 to 49 days of age. At the end of each experiment, two chickens of each replication were sacrificed and their tibiae were collected for analysis of bone characteristics: bone measurements (weight, length and thickness of the compact and spongy layers) and bone density (bone density). A total of 540 birds were used in each experiment, divided into fully randomized blocks with a 3 x 2 factorial scheme, that is, three amino acid profiles (methionine, lysine and threonine – 100, 125 and 150% of NRC recommendations, 1994) and two calcium levels (75 and 100% of NRC recommendations, 1994), with 30 birds per replication. There were not interactions between the two factors. The amino acid or calcium levels did not affect bone density and tibia variables in both strains.

Ao final de cada experimento, foram abatidas duas aves de cada repetição para coleta das tíbias para análise das características ósseas: medidas ósseas (peso, comprimento, espessura da camada compacta e esponjosa da tíbia) e a densidade óssea (densitometria óssea). Em cada experimento foram utilizadas 540 aves, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 3x2, ou seja, três níveis de aminoácidos (metionina, lisina e treonina - 100, 125 e 150% NRC,1994) e dois níveis de cálcio (75 e 100% NRC,1994), com 30 aves por repetição. Não foram encontradas interações entre os dois fatores estudados. Os níveis de aminoácidos ou de cálcio não afetaram a densidade óssea e as variáveis da tíbia em ambas as linhagens.Editora da Universidade Estadual de Maringá2008-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/64710.4025/actascianimsci.v28i2.647Acta Scientiarum.
