performance and bone strength of male broiler chickens. Diets were arranged factorially (2&times;3&times;2) consisted of a positive control with adequate Ca (10.4 g/kg diet) and nonphytate P (NPP 5 g/kg diet) exceed the requirements suggested in the Ross 308 broiler nutrient specifications and a negative control diet with Ca (7.3 g/kg diet) and nonphytate P (NPP 5 g/kg diet ), three levels of<i>&nbsp;</i>WC (0, 100 and 200 mg/kg diet), and two levels of 1, 25-dihydroxycholecalciferol (0 and 0.5 &mu;g/kg diet). Reducing the dietary Ca level by 30 % decreased tibia diameter (P<0.05) at 42 day of age. Bone fracture energy significantly increased with supplementation of 1, 25-dihydroxycholecalciferol at 42 day of age (P<0.01). Supplementation of 100 mg/kg WC significantly increased shear force (P<0.05) and fracture energy (P<0.01) at 42 day of age. At 21 day of age birds provided with 100 mg/kg of WC had a significant higher cortical thickness and tended to increase at 42 day. The results of this experiment indicated that supplementation of 100 mg/kg fruit hydro alcoholic extract of WC<i>&nbsp;</i>exhibit beneficial effects on bone characteristics without any adverse effects on productive performance.</p> 1 و 25 دی هیدروکسی کوله کلسیفرول, پنیر باد, استحکام استخوان, جوجه گوشتی 1, 25-dihydroxycholecalciferol, Withania coagulans, Bone strength, Broiler chickens 9 18 http://rap.sanru.ac.ir/browse.php?a_code=A-10-1-96&slc_lang=fa&sid=1 Seyed Javad Hosseni سید جواد حسینی 100319475328460010211 100319475328460010211 Yes Ferdowsi University of Mashhad دانشگاه فردوسی مشهد Hassan Kermanshahi حسن کرمانشاهی 100319475328460010212 100319475328460010212 No Ferdowsi University of Mashhad دانشگاه فردوسی مشهد Hassan Nassirimoghadam حسن نصیری مقدم 100319475328460010213 100319475328460010213 No Ferdowsi University of Mashhad دانشگاه فردوسی مشهد Abolghasem Nabipour ابوالقاسم نبی پور 100319475328460010214 100319475328460010214 No Ferdowsi University of Mashhad دانشگاه فردوسی مشهد Ahmad Hassanabadi احمد حسن آبادی 100319475328460010215 100319475328460010215 No Ferdowsi University of Mashhad دانشگاه فردوسی مشهد
