日粮中添加柯力能对断奶仔猪生产性能的影响

The Effect of Kenon Emulsifier Supplemented in Feed on Growth Performance in Weaned Piglets

本试验对乳化剂柯力能对断奶仔猪脂肪消化和生产性能的影响进行了研究。试验采用单因子设计。将240头35日龄PIC断奶仔猪随机分成4个处理组1处理组1：豆油（对照组）；处理组2：豆油＋乳化剂；处理组3：猪脂（对照组）；处理组4：猪脂＋乳化剂]，每组3个重复，每个重复20头。对照组采用玉米一豆粕型基础日粮，其中添加了5％的豆油或猪脂，试验组除此外分别添加了400g/吨的柯力能。试验9n,4定各组仔猪的平均日增重、平均日采食量、料重比等生长性能指标和腹泻频率。试验结果表明，断奶仔猪日粮中添加柯力能可以有效改善断奶仔猪的生产性能，降低断奶仔猪因为油脂过量添加引起的营养性腹泻频率。

This experiment was conducted to study the effects of Kenon emulsifier supplemen- tation in diets on fat digestion and growth performance of weaned piglets. A randomized complete design with single factor was adopted in the experiment and 240 35 - day - old weaned PIC piglets were randomly divided into four treatment groups （ Group 1 ： soybean oil （ control ） ; Group 2 ： soybean oil ＋emulsifier; Group 3： lard （Control）; Group 4： lard ＋ emulsifier） with three repli- cates in each group and 20 piglets in each replicate. The piglets of control groups were fed corn - soybean meal based diets, in which were added 5% soybean oil or lard, while the piglets of ex- perimental groups were fed diets with 400g / t Kenon emulsifier besides 5% soybean oil or lard. ADG, ADFI, and FCR, as well as diarrhea frequency, were measured in this study. The experi- mental results showed that Kenon emulsifier supplementation in diets could effectively improve growth performance of weaned piglets and reduce nutritional diarrhea caused by adding excess fat.
