“…GARCIA et al (2002) evaluated the inclusion of different amounts of canthaxanthin (0, 12, 24, 36, 48 and 60mg kg -1 of feed) in the diet of laying hens and concluded that the inclusion of canthaxanthin in the diet did not affect production parameters, except for the pigmentation of egg yolks. TORRES et al (2009) supplemented breeders with 25-(OH)-D3 and observed no effect on egg production during the period of 32-67 weeks. However, egg shell quality, measured by specific gravity, improved with 25-(OH)-D3 supplementation in breeders aged 60 weeks.…”

“…In the final stages of incubation, however, the increase in the metabolism of the embryo leads to higher oxygen consumption and increased lipid oxidation in the yolk to meet the energy requirements of the embryo (LATOUR et al, 2000). TORRES et al (2009) found lower mortality of embryos in breeders supplemented with 25-(OH)-D3. According to the authors, the decrease in embryonic mortality may be related to the increased availability of calcium for the formation of the chick skeleton.…”

“…Waldroup et al (1965) mostraram que o requisito pode variar de 5 mg/kg sob teores de Ca e P normais e, mais de 40 mg/kg quando as quantidades ou proporções de Ca e P foram abaixo do ideal. Williams et al (2000) e Bar et al (2003) sugeriram que as necessidades de cálcio para genótipos modernos de frango de corte está próximo de 13 g/kg do que o valor de 10 g/kg sugerido pelo NRC (1994).…”

RESUMOA disponibilidade e o nível adequado de vitamina D deve atender à demanda fisiológica para formação óssea, e reduzem a ocorrência de problemas locomotores em frangos de corte. Com o objetivo de avaliar três níveis de vitamina D sobre o desempenho, força de ruptura e conteúdo mineral das tíbias de três linhagens de frangos de corte, foram utilizado 1.440 pintos de um dia, distribuídos em um delineamento inteiramente casualizado em esquema fatorial 3x3, com três linhagens (Ross 308, Cobb 500 e Hybro) e três níveis de inclusão de vitamina D 3 (1250 UI vitamina D 3; 3000 UI vitamina D 3 e 2760 UI de hidroxicolecalciferol 25(OH) D 3 , fornecidos na ração até o 21º dia de vida, com oito repetições de 30 aves por parcela, totalizando 160 aves por tratamento. Não houve diferenças (P>0,05) entre os níveis de vitamina D, e as linhagens para o desempenho e força de ruptura, exceto para o consumo de ração para o fator linhagem (P<0,05), devido ao seu potencial de crescimento. Os níveis de vitamina D não influenciaram (P>0,05) as quantidades de cálcio e fósforo nas tíbias. No entanto, para as linhagens houve diferença significativa (P<0,05) aos 14 dias de idade, com maior quantidade de cálcio para o Ross 308 e maior quantidade de fósforo para o Hybro, evidenciando diferenças no metabolismo do cálcio e do fósforo em frangos de corte. Em conclusão a adição de 1250 UI de vitamina D/kg de ração é suficiente para garantir o desempenho e o desenvolvimento ósseo de frangos de corte, independente da linhagem a ser utilizada, mediante ao ajuste correto dos níveis de Ca e P. PALAVRAS-CHAVE:Cálcio. Força de ruptura. Fósforo. Hidroxicolicalciferol. Linhagens. SUMMARYThe availability and appropriate level of vitamin D to promote physiological demand, bone formation and reduce the occurrence of locomotors problems in broilers. The aim of this study was to evaluate three levels of vitamin D on performance breaking strength and mineral content of tibia of three strains of broilers, it was used 1,440 chicken of one day of age. The complete random design used was in factorial 3X3, with three strains (Ross 308, Cobb 500 and Hybro) and three inclusion levels of vitamin D3 (1250 IU vitamin D3; 3000 IU vitamin D3 and 2760 UI of 25-hydroxycholecalciferol (OH) D3), provided in the diet until 21 day of life, with eight replicates of 30 birds per group, a total of 160 birds per treatment. There was no difference (P> 0.05) between the levels of vitamin D, in the strains for the perfomance and breaking strength, except for feed intake for the strain factor (P <0.05), with higher feed intake of Cobb, probably due to its higher growth potential. The levels of vitamin D had no influence significant (P> 0.05) the quantities of calcium and phosphorus in the tibia bones. However, for strains was significant difference (P <0.05) at 14 days of age, with higher amounts of calcium to Ross 308 and higher amount of phosphorus to Hybro. This can be explained because of the genetic variation in metabolism of calcium and phosphorus in broilers. In conclusion th...
