| Abstract | |
The effects of nutrition in ovo with vitamin D3 and hydro diet containing sodium alendronate on bone development and performance parameters were evaluated on this study. The experiment consisted in two stages (hatching and growing). The incubation period and the experimental design was completely randomized with five treatments (not injected eggs; injected only with olive oil; 1.2μg; 2.4 μg and 3.6 μg of vitamin D3 / 100 μL of olive oil) injection of vitamin D3 in 600 fertile eggs of matrices broilers, favoring a challenge to the next stage, ie, a lower bone promoting embryonic development, generating a challenge for the growing phase to test the levels of AS. The stage of growing design was completely randomized in a factorial 2 x 5 (vitamin D3 during the incubation period and different concentrations of AS in the growing period). The vitamin D3 nutrition in egg hatchability did not affect (P> 0.05), however, negatively affected the bone densitometry post-hatch chicks, as the sodium alendronate showed no significant data (P> 0.05) for bone development parameters. However, it is concluded that further studies are necessary to determine the levels of this drug in order to improve the bone condition of broilers. (AU) | |
