摘要
为研究微囊丁酸钠对保育猪生长性能的影响,选择200头日龄、体重接近的保育仔猪(杜×长×大),随机分为2个处理组,每组4个重复(栏),每个重复25头。对照组饲喂基础饲粮,试验组饲喂基础日粮+1000 g/t微囊丁酸钠。结果表明:与对照组相比,日粮添加1000 g/t微囊丁酸钠,仔猪腹泻状况明显改善,平均日采食量提高了7.13%(P>0.05),平均日增重提高了17.34%(P<0.01),料重比降低了8.61%(P<0.05);试验全期试验组每头保育仔猪经济效益较对照组提高了28.08%。以上结果表明,饲粮中添加微囊丁酸钠不仅可以提高保育仔猪的平均日增重,降低料重比及缓解腹泻情况,而且还可以提高保育仔猪的净利润,提高养殖场的经济效益。
To study effects of microencapsulated sodium butyrate on growth performance of nursing piglets,a total of 200 nursing piglets （DurocxLandracexLarge white） with similar age and body weight were collected and randomly allocat- ed to two treatments with four replicates of 25 each.The control group was fed with basal diet.The experimental group was fed with basal diet ＋1000 g/t microencapsulated sodium butyrate.The results showed that：compared with control group, when 1000 g/t microencapsulated sodium butyrate were added in the diets,the diarrhea of piglets was significantly re- lieved, average daily feed intake （ADFI） and average daily gain （ADG） increased by 7.13% （P 〉 0.05） and 17.34% （P 〈 0.01） respectively, and feed to gain ratio decreased by 8.61%（P 〈 0.05）.The average economic benefits increased by 28.08% during the whole trial period compared with control group.The results above indicated that the average daily gain （ADG） increased,feed to gain ratio and diarrhea decreased,and the net profits and economic benefits increased by adding mieroeneapsulated sodium butyrate in diet.
