1α-羟基维生素D3和植酸酶对22～42日龄肉鸡生长性能、胫骨发育和肉品质的影响
Effects of 1α-OH D3 and Phytase on Growth Performance, Tibia Development, and Meat Quality of Broilers Aged from 22 to 42 Days
摘要
Abstract
This experiment was conducted to evaluate the effects of 1α-OH D3 , and interaction between 1α-OH D3 and phytase on growth performance, tibia development, and meat quality of broilers aged from 22 to 42 days.Two trials were conducted in this study. In trial 1, ninety-six Arbor Acres ( AA) broilers at 21 days of age with the same diet were allotted to 2 treatments with 4 replicates. Two diets in trail one were the basal diet 1 ( NPP 0.13％. TP 0. 35％ ) and the experimental diet, which was the basal diet 1 supplemented with 5 μg/kg of 1α-OH D3. In trial 2. a 2 ×2 factorial design was conducted to test the effects of supplementing 0 and 5 μg/kg 1α-OH D3 in combination with 0 and 500 U/kg phytase based on the basal diet 2 ( NPP 0. 20％. TP 0. 42o％ ).The fifth diet served as a control ( NPP 0. 35％, TP 0. 57％ ) . The results showed that tibia quality , plasma concentration of inorganic phosphate, and lightness of thigh meat were increased, while shearing force of thigh meat was decreased by dietary supplement with 1α-OH D3, however. dietary supplement with 1α-OH D3 did not significantly affected growth performance of broilers. When phytase was added, growth performance and tibia quality were improved, while yellowness and water-holding capacity of breast meat were declined. Dietary supplement with 1α-OH D3 and phytase did not improve growth performance, but the interaction between 1α-OH D3 and phytase increased the contents of tibia ash and phosphate. In conclusion, the addition of 1α-OH D3 individually or together with phytase improves the quality of bone and meat in broilers aged from 22 to 42 days.
