ABSTRACT
The objective of this study was to evaluate the performance of broiler chicks in the first week of age. The study was performed with the inclusion of two vitamin D metabolites as the only source of vitamin D in the broilers diet. For this purpose, 308 768-day-old male Ross chicks were used, hosted in 96 pens of 0.36 m2 each. The experiment consisted of six treatments distributed in a completely randomized block design, in a factorial model of 2 x 3. Two vitamin D metabolites 25-hydroxy cholecalciferol and 1,25-dihydroxycholecalciferol and three levels of inclusion of each metabolite (34.5, 69.0 and 93.5 μg/kg) and (0.5, 1.0 and 1.5 μg/kg), respectively. The experiment was performed with 16 replications per treatment and eight animals per experimental unit. The main parameters of study were: final body weight (BW), average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR) and mortality (M). The birds fed with 25-hydroxy cholecalciferol presented a better ADG (p = 0.03) and ADFI (p = 0.00) in contrast to the 1,25-dihydroxycholecalciferol, FC (p = 0.16) and M (p = 0.37) were not affected by the vitamin D metabolite. The use of 34.5 μg/kg of metabolite 25-hydroxy cholecalciferol fed during the first week of life to the broilers show better zootechnical results with respect to 1,25-dihydroxycholecalciferol. This study led to the conclusion that 1,25-dihydroxycholecalciferol is not recommended as the only source of vitamin D when it comes from an herbal source.
