【摘要】 在断乳仔猪日粮中添加脂肪酸优化的脂肪源,同时以椰子油粉作为对照,研究优化的脂肪源对断乳仔猪生长性能、腹泻情况及生产效益的影响。试验选取120头断乳仔猪,随机分为2个处理组:A组添加4%结构脂脂肪粉(商品名:乳脂能Ⅱ型),B组添加4%椰子油粉(商品名:椰香50),每组6个重复,每个重复10头猪,试验为期12 d。结果表明:A组仔猪的采食量、日增重及成活率均高于B组,且A组仔猪的腹泻率显著低于B组。经济效益分析表明:试验期间,A组每头猪增重回报比B组增加15.52元/头,净盈利增加13.54元/头。由此可见,脂肪酸优化的结构脂可促进仔猪采食,提高仔猪增重,减少仔猪腹泻,且其经济效益优于B组。更多还原

【Abstract】 An optimized fat source of fatty acids was added to the diet of weaned pigs and coconut oil powder was used as control,studied the effects of optimized fat source on growth performance, diarrhea and production efficiency of weaned piglets. 120 weaned pigs were selected and randomly divided into 2 treatment groups: group A add 4% structure fat powder(trade name: Ru zhi neng Ⅱtype), group B add 4% coconut oil powder(trade name: Ye xiang 50), each group 6 repeat, each repeat 10 pigs, test for 12 days. The results showed that feed intake, daily weight gain and survival rate of piglets in group A were higher than those in group B, and the diarrhea rate of piglets in group A was significantly lower than that in group B. Economic effect analysis showed that during the experiment, the weight gain of per pig in group A increased by 15.52 yuan/head compared with group B, and the net profit increased by13.54 yuan/head. Thus, the optimized structure of fatty acids can promote piglet food intake, increase piglet weight gain and reduce piglet diarrhea, and their economic benefits are better than group B.更多还原
