摘要
研究流食与颗粒料不同方式对断奶仔猪增重和采食量,选择杜长大三元杂种28日龄仔猪,随机区组设计,共六个区组,每窝一个区组,每个区组四头猪,分为处理组2头和对照组2头。28日龄体重：试验组7.19±0.027 Kg,对照组7.19±0.031 Kg。处理组和对照组均自由采食,自由饮水,35日龄晨称个体重,结果给予流食比使用颗粒料提高仔猪采食量33g/d（P〈0.05）和日增重17.6g/d（P〈0.05）。仔猪早期断乳是提高母猪生产力和规模化养猪业中的关键技术之一,现代规模养猪业已把乳猪断奶日龄提至21~28 d。
This study aimed to determine the effects of different feeding method including liquid diet and pellet feed on weight gain and feed intake of weanling piglets.Weanling pigles（Duroc ×Landrace×Large Yorkshire） with 28 days old were divided into 6 groups with randomized block design,4 pigs in each block,2 pigs in experimental group and 2 pigs in control group.28-d body weights of experimental group and control group were 7.19±0.027Kg and 7.19±0.031Kg,respectively.Feed ad libum and free water were provided for experimental group and control group.35-d body weight results showed that feed intake and daily weight gain in liquid diet group increased 33g/d（P0.05）and 17.6g/d（P0.05） compared to pellet feed group.Early weanling of piglets is one of the key techniques of improving sow productivity and large-scale swine industry,weanling age can reach up to 21 to 28 days in modern swine industry.
