Evaluation of the Sensitivity and Specificity of the New Clinical Diagnostic and Classification Criteria for Kashin-Beck Disease,an Endemic Osteoarthritis,in China

This study aimed to evaluate the sensitivity and specificity of the new clinical diagnostic and classification criteria for Kashin-Beck disease （KBD） using six clinical markers： flexion of the distal part of fingers, deformed fingers, enlarged finger joints, shortened fingers, squat down, and dwarfism. One-third of the total population in Linyou County was sampled by stratified random sampling.

日粮中添加发酵木薯渣对哺乳母猪的影响

本研究旨在探讨日粮中添加发酵木薯渣对哺乳母猪生产性能和便秘情况等的影响,即选取14头体况和预产期相近的长×大二元杂母猪,根据胎龄和体况等参数随机分为对照组和试验组,每组设7个重复,每个重复1头母猪。在饲养管理和免疫程序等方面均一致的条件下,探讨使用发酵木薯渣替换日粮中麸皮对哺乳母猪生产性能的影响。试验周期为从母猪妊娠107 d转入产房直至断奶(仔猪21日龄断奶)后发情,约35 d。结果显示:哺乳母猪日粮中用4%的发酵木薯渣替代麸皮能提高哺乳母猪的采食量、仔猪平均日增重和断奶窝增重,提示日粮中适量添加发酵木薯渣有利于提高哺乳母猪的生产性能。
