试验旨在研究益生菌对维生素K（V（k））缺乏肉鸡骨骼健康的改善作用。试验选用360只爱拔益加肉仔鸡,采用3×2因子试验设计,分成6个处理组,每组3个重复。饲喂日粮中不添加益生菌或者添加500 g/t的枯草芽孢杆菌（BS）或凝结芽孢杆菌（BC）,公、母鸡分栏饲养。所有处理组的日粮均不额外添加V_（ko）结果显示：在0~42日龄,添加BS和BC均有增加肉鸡日增重（P=0.078）和降低料重比（P=0.079）的趋势。添加BS增加了21日龄肉鸡的股骨和胫骨重以及42日龄胫骨重,两种益生菌均增加21日龄胫骨强度和钙量（P〈0.05）。益生菌和性别对21日龄胫骨的灰分含量以及42日龄胫骨长度、灰分含量、钙量和磷量存在互作效...

This study was conducted to investigate the effect of probiotics on bone health of broiler chickens fed vitamin K（_（K））-deficient diet. The trial was adopted 3×2 factorial arrangement and a total of 360 Arbor Acres chickens were randomly divided into six groups, with three replicates per group. The basal diet was supplemented without probiotic, or with 500 g/t of Bacillus subtilis（BS） or Bacillus coagulans（BC）. The male and female chickens were separately reared. All diets were formulated without extra addition of V_（K）. The results ...
