【摘要】 从1982年至今,经38743只雏鸡自然发生鸡白痢病的防治实验应用雏鸡乳杆菌防治的有效率达96％;同时,治疗组的雏鸡比未用雏鸡乳杆菌的雏鸡多增重14％。经过追踪检查,使用雏鸡乳杆菌防治的雏鸡,它们对鸡沙门氏菌的反应为阴性;使用雏鸡乳杆菌防治过的雏鸡,其肠道中乳杆菌的均数值的对数为11.2±0.5;未用雏鸡乳杆菌处理的对照雏鸡,其肠道中乳杆菌的均数值对数为7.6±0.4(正常鸡肠道中乳杆菌的均数值对数为9.5±0.5[5])。更多还原

【Abstract】 From 1982 till now, the rate of successful control of 38.743 chickens against natural infection by Salm. pullorum reached 96%; Meanwhile, the chickens treated with Lactobacillus gallination were 14% increase of body weight than those untreated with the above bacterial preparation. Through a tracking survey the following results were obtained. chickens which were given Lactobacillus gallinaceus for the contrcl of disease were not infected with Salmonella pullorum. The average number of Lactobacilli (in log 10/g)in the intestine of chiekens treated with Lactobacillus gallinaceus is 11.2±0.5; whereas the average number in log 10/g of Lactobacillus gcllinaccus in the intestine of chickens which were not given Lactobacillus gallinaceus was found to be 7.6±0.4 (the normal value of healthy chicken found being 9.5±0.5).更多还原
