摘要
为复方金荞麦饲料添加剂在养猪生产上的应用提供理论依据,选用60日龄,体重20kg左右的大约克×长白二元杂交生长猪40头,随机分为4组(对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ组分别饲喂基础日粮+1%、2%、3%的复方金荞麦饲料添加剂),每组10头,进行了复方金荞麦饲料添加剂对瘦肉型猪生长性能的影响试验。结果表明:试验Ⅰ、Ⅱ、Ⅲ组的日增重分别比对照组高2.27%(P>0.05)、10.34%(P<0.01)、12.85%(P<0.01),料重比分别比对照组低6.34%(P<0.05)、9.22%(P<0.05)、11.53%(P<0.01),经济效益分别比对照组高4.86%(P>0.05)、12.70%(P<0.05)、16.57%(P<0.01)。复方金荞麦饲料添加剂可促进瘦肉型猪的生长、提高饲料转化效率和养殖经济效益,添加量以3%为宜。
To provide a theoretical basis for the application of compound buckwheat feed additives in pig production,40growing pigs（Landrace× Yorkshire）weighted about 20kg were allotted to four treatments with 10pigs per group in 60days.The control group was fed with basal diet and the test group 1,2and 3were respectively fed with basal diets added with 1%,2% and 3% compound buckwheat feed additives.The results were as follows：compared with the control group,the ADG of test group 1,2and 3 were respectively increased by 2.27%（P〉0.05）,10.34%（P〈0.01）and 12.85%（P〈0.01）.And FCR was decreased by 6.34%（P〈0.05）,9.22%（P〈0.05）and 11.53%（P〈0.01）.The economic benefits were respectively higher than control group by 4.86%（P〉0.05）,12.70%（P〈0.05）and 16.57%（P〈0.01）.Compound buckwheat feed additives could improve the growing characteristics and FCR in growing and fattening of lean hogs and the adding amount of 3% had the best effect.
