饲料加工方式对育肥猪生长性能、养分消化及胴体性状的影响

Effects of Feed Processing Methods on Growth Performance,Nutrient Digestion and Carcass Traits of Finishing Pigs

该研究主要探讨饲料加工方式不同,对育肥猪生产性能、消化性能、酮体性状的影响。从某规模化养殖场中选择120头年龄在12周龄,平均体重在41.7 kg的商品育肥猪,按照随机原则将其划分成4个组别,每组30头,分别命名为试验1组、试验2组、试验3组和对照组,对照组采用颗粒饲料投喂,其他3个试验组别选择粉碎粒度不同的饲料进行投喂。结果表明,粉碎饲料有利于提高猪群的日采食量,同时随着饲料粉碎细度的逐渐增加,育肥猪的日增重呈逐渐升高的态势。粉碎饲料有利于提高猪群的生猪和消化功能,值得在今后生产过程中推广应用。

This study mainly explores the effects of different feed processing methods on the production performance,digestion performance and ketone traits of fattening pigs.From a large-scale farm,120 commercial fattening pigs aged 12 weeks old and average weight 41.7 kg were selected,and they were divided into 4 groups according to the random principle,each group of 30 pigs were named as a test group,Test two,test three,and control group.The control group was fed with pelleted feed,and the other three test groups chose to feed with feeds with different crushing particle sizes.Research results show that daily feed intake of fattening pigs increased with the increase of feed grinding fineness,and the daily weight gain of fattening pigs increased gradually.Comminuted feed is beneficial to improve the function of pig and digestion,and it is worth popularizing and applying in the production process in the future.
