Özet

In this study, the effects of boric acid addition to broiler diets in different rearing periods on growth performance, cholesterolemia, carcass and some bone characteristics were investigated. For this purpose, 96 one day old broiler chickens (Ross 308) were randomly assigned in 4 equal groups according to the modalities of boron supplementation: whereas birds of the control group were fed with basal diets, the others were supplemented with boric acid (60 mg/kg of food/day) during the starting (first 21 days, group T1), the finishing (last 21 days, group T2) and the whole experimental (42 days, group T3) periods. Boric acid addition has induced no significant effects on growth performance, carcass characteristics and cholesterolemia but significant increased calcium and phosphorus deposition in tibia bone ash was evidenced in treated broilers, especially those supplemented for the finishing period. These results suggest that dietary boric acid supplementation may be a useful practice for improving bone characteristics in broilers.
