白酒糟饲喂三穗鸭的增重及饲料转化效果

摘要

To explore the rational utilization of brewer’s grains in Sansui Duck breeding,280 healthy Sansui ducks(21 days old)were selected and randomly divided into four groups to study the effects of different daily ration of brewer's grains on the weight gain and feed efficiency.Results:the daily gain of Sansui Duck fed with mixed feed(CK)was the highest(16.7 g),respectively higher than GroupⅠ(90%mixed feed+10% brewer's grains),GroupⅡ(85% mixed feed+15% brewer’s grains)and Group Ⅲ(80%mixed feed+20% brewer's grains)by 5.7%(P >0.05),21%(P 0.05)respectively;The energy conversion efficiency of Group Ⅱ was the highest(0.57),higher than CK,GroupⅠ and Group Ⅲ by 23.9%(P 0.05)separately;The protein efficiency ratio of CK was the highest(1.65),respectively higher than GroupⅠ,Group Ⅱ and Group Ⅲ by 13% (P < 0.05),46% (P < 0.05)and 42.2% (P < 0.05) respectively.It was optimum to replace mixed feed by 10% brewer's grains in 4~10 week age of Sansui duck,which had no obvious influence on the growth performance and feed conversion efficiency.%为白酒糟资源在三穗鸭养殖上的合理利用，选取21日龄健康三穗鸭280只，随机分为4组进行了不同白酒糟水平日粮对其增重及饲料转化效率的影响试验。结果表明：日增重以饲喂配合饲料（对照组）的最高，为16．7 g，分别比试验Ⅰ组（90％配合饲料＋10％白酒糟生物饲料）、试验Ⅱ组（85％配合饲料＋15％白酒糟生物饲料）、试验Ⅲ组（80％配合饲料＋20％白酒糟生物饲料）高5．7％（P ＞0．05）、21％（P ＜0．05）和16％（P ＜0．05）。料重比以试验Ⅱ组最高，为5．5，分别比对照组、试验Ⅰ组、试验Ⅲ组高41％（P ＜0．05）、25％（P ＜0．05）和1．9％（P ＞0．05）；代谢能增重效率以试验Ⅱ组最高，为0．57，分别比对照组、试验Ⅰ组、试验Ⅲ组高23．9％（P ＜0．05）、18．8％（P ＜0．05）和5．6％（P ＞0．05）；蛋白质效力比以对照组最高，为1．65，分别比试验Ⅰ～Ⅲ组高13％（P ＜0．05）、46％（P ＜0．05）和42．2％（P ＜0．05）。在4～10周龄三穗鸭日粮中用10％的白酒糟生物饲料代替配合饲料较适宜，对其生长性能和饲料转化效率无明显影响。
