| 摘 要： | 基础日粮中添加１％ Ｋ９４ 复合活菌剂饲喂 １ 日龄ＡＡ 鸡，以添加不含活菌的 Ｋ９４ 辅料为对照，分别于２ 周和４ 周后，测定平均日增重，以及饲料中干物质（ＤＭ ）和粗蛋白质（ＣＰ）消化率，并对盲肠微生物进行计数。结果表明，Ｋ９４ 能明显提高 ＡＡ 肉鸡的生产性能，提高饲料转化率，并在饲喂 ４ 周后使采食量提高；促进ＤＭ 和ＣＰ的消化；同时改变盲肠菌群的比例，使 １～１５ 日龄鸡需氧菌总数和大肠杆菌数量减少，１～１５ 日龄和 １６～３０ 日龄鸡盲肠厌氧菌总数、厌氧乳杆菌、梭状芽胞杆菌以及双歧杆菌数量均增加。 |

| Abstract: | In order to observe the effect of K94 compound biologics on performance of broilers,1% K94 was added to basal diets to feed AA broilers with 1\|day\|old for 4 weeks.Body weight and feed intake were measured weekly.From 13 to 15 and from 27 to 30 day old,apparent digestibility of dry mater(DM) and crud protein(CP) were determined.When 15\|and 30\|day old,10 birds slected ramdomly were killed,and cecal contents were collected to enumerate microbial populations.Compared with control,the mean body weight gain,feed intake,feed conversion,apparent digestibility of DM and CP of feed were increased.There were also increase in numbers of total anerobes,bifidobacteria,lactobacillus and clostridum,but decrease of total aerobes and coliforms numbers. |
