益生菌对快大黄羽肉鸡生产性能的影响

Effects of Probiotics on the Production Performance of Fast - large - scale Yellow - feathered Chicken

本文以益生菌（FM—B11，富乐美）为研究对象，该产品由美国的阿肯色大学家禽研究所研制，是从养殖生产的大量健康鸡群的肠道菌群中分离、筛选、培育出的11种益生菌复合制剂（以乳酸菌为主）。本试验选取金浪服务中心同一孵化场的相同月份出雏的快大型黄羽肉鸡，随机选取对照组养户7户，试验组养户7户，试验组养户饲养全程投服富乐美3次，通过计算分析对照组和试验组在上市时的成活率、上市率、料肉比、公鸡和肉鸡的平均日增重等数据，从而研究益生菌对快大黄羽肉鸡生产性能的影响。试验结果表明，使用益生菌后的试验组能提高快大黄羽肉鸡的成活率、上市率，显著提高了日增重以及明显降低了料肉比。

In this paper, probiotic （FM -B11, Fuller U. S. ） as the research object, the product of the University of Arkansas poultry from the United States is developed by the Institute, from the actual production of a large number of health promoting bacteria in the chickens of separation, screening, breeding 11 probiotics （mainly by lactic acid bacteria）. The golden wave of service centers were selected hatcheries in the same month of the same fast - large - scale yellow -feathered chickens, raising households randomly selected seven control groups, seven experimental groups raising families, keeping families raising test group Fuller throughout the United States investment services the probiotics for 3 times, analyzed by calculating the control group and experimental group survival time of listing, the listed rate, feed conversion, rooster and chicken items average daily gain of these data to study probiotics for the production performance of fast - large -scale yellow- feathered chicken. Experimental results showed that the experimental group after the use of probiotics improved the survival rate of fast - large - scale yellow - feathered chicken, listed rate, significantly improved daily gain and significantly reduced feed conversion ratio.
