Effects of calcium to non-phytate phosphorus ratio and different sources of vitamin D on growth performance and bone mineralization in broiler chickens

Durante a realização da TC consegue-se acompanhar o deslocamento da mesa de tratamento em relação ao eixo dos YY, o tempo de realização da TC, a taxa de dose (Fig.

(1998) abordam a generalização da pesquisa qualitativa pelo método estudo de caso. Segundo eles o estudo de caso único se distingue dos estudos de casos múltiplos por

The supplementary levels of calcium and vitamin D in meat-type quail between 15 and 35 days of age required for maximum growth and performance is greater or equal to 0.90% of

Dietary NPP levels significantly affected growth performance and tibia mineralization (except width) of broilers; by contrast, meat yield and organ relative weight were not

Therefore, this study aimed at the evaluating the effects of different dietary vitamin D sources and calcium levels on the production performance, egg quality, and bone strength

This experiment was conducted to evaluate the combination effect of low dietary non-phytate phosphorus (NPP) concentrations, phytase (PHY) levels, and

Therefore, the aim of the present study was to determine the effects of using D 3 and 25-OHD 3 as isolated or associated sources of vitamin D in different proportions on
