不同微生态制剂对雏鸡实验感染鸡白痢沙门氏杆菌的影响

Different Microecological Preparations' Influence on Chicks Inoculated with Salmonella pullorum

以不同微生态制剂饲喂 1日龄雏鸡 ,连喂 7d.在雏鸡 3日龄时经口接种鸡白痢沙门氏杆菌 ,30日龄检测雏鸡消化道菌群 ,统计育雏成活率 .结果表明 ,给雏鸡早期饲喂微生态制剂对实验感染鸡白痢沙门氏杆菌有预防作用 .

Different microecological preparations were used to feed 1 day old chicks for 7 days successively.These chicks were inoculated with Salmonella pullorum by oral when they were 3 days old.The dynamics of bacteria in their alimentary tract and the livability of chicks were studied when they were 30 days old.The results showed that the microecological preparations could prevent chicks from being infected with Salmonella pullorum experimentally if they were fed to chicks at the early stage of chick growth.
