dc.description.abstractThe aim of this study was to assess the characteristics of the tibiotarsus of male broilers at 21 and 35 days of age. The percentages of collagenous proteins (CP), non-collagenous proteins (NCP), ash, and minerals (calcium, phosphorus, potassium and sodium), as well as weight of dried and defatted tibiotarsus in natura were determined. A total of 648 Cobb® male broilers were used in a random block design study with 6 treatments, 6 replicates, and 18 birds per experimental unit. The treatments consisted of diet supplementation with 0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 μg of active vitamin D 3 per kg of feed. The birds were weighed at 21 and 35 days of age and one bird per repetition with the mean weight of the experimental unit was slaughtered to collect the tibiotarsus. The organic and mineral composition of the bone was affected by the addition of active vitamin D 3 to the feed. Our results indicate that a dose of up to 1.50 μg of 1,25(OH) 2 D 3 /kg of feed is ideal for male broilers between 8 and 35 days of age.en
dc.description.abstractO objetivo do trabalho foi avaliar as características dos tibiotarsos de frangos de corte machos aos 21 e 35 dias de idade. Foram determinados os percentuais ósseos de proteínas colagenosas (PC), proteínas não colagenosas (PNC), cinzas e minerais (cálcio, fósforo, potássio e sódio), além dos pesos dos tibiotarsos in natura, secos e desengordurados. Foram utilizados 648 frangos de corte machos da marca comercial Cobb® em um delineamento em blocos ao acaso com seis tratamentos e seis repetições com 18 aves por unidade experimental. Os tratamentos consistiram na suplementação de 0,0; 0,5; 1,0; 1,5; 2,0 e 2,5 μg de vitamina D 3 ativa/kg de ração. Aos 21 e 35 dias de idade as aves foram pesadas e um frango/repetição com o peso médio do lote foi retirado e abatido para se obter os tibiotarsos. A composição orgânica e mineral dos ossos foi afetada pelo fornecimento suplementar de vitamina D 3 ativa nas rações. Recomenda-se até 1,50 μg de 1,25(OH) 2 D 3 /kg de ração para frangos de corte machos de 8 a 35 dias de idade.pt-BR
