【摘要】 LB乳酸菌的菌体细胞及培养过程中所分泌的产物经热灭活而制成的产品可以抑制或杀灭肠道的致病菌,刺激有益微生物的生长。竹丝鸡这一品种,对胃肠道疾病的抵抗能力较差,在生长过程中,易受到沙门氏菌、大肠杆菌及一些肠道病原的影响。本研究通过在竹丝种鸡上应用乐托尔,与大生产进行对比,结果显示,使用乐托尔的竹丝鸡在抗病力、死淘率、种蛋色泽、产蛋率、孵化率等指标上均优于大生产。更多还原

【Abstract】 Inactivated Lactic bacillus cells and its secretory products in the culture have been developed as a microflora and used to kill or inhibit chicken enteropathogens and stimulate growth of normal flora. Zhu Si chicken is a breed sensitive to enteropathogens such as Salmonella, E. coli and some enteropathogens during its growing stage. Some experiments were conducted in Zhu Si breeders to evaluate the use of Letuor as feed additive and the usefulness in improving chicken production. Chickens feed with Letuor showed superior resistant to infections, lower mortality, better quality and quantity of egg production than control chickens.更多还原
