摘　　要：本试验旨在研究夏季不同饲喂次数和料水比对两广小耳花猪生产性能的影响,选择48头两广小耳花猪哺乳母猪,分为4组,每组12头母猪。4个处理组的饲喂方式分别为饲喂2次/d和料水比为1∶2.5(对照组)、饲喂2次/d和料水比为1∶3.5、饲喂3次/d和料水比为1∶2.5、饲喂3次/d和料水比为1∶3.5。监测母猪从产后至断奶25 d的采食量、仔猪生长性能以及环境温湿度等指标。结果表明:饲喂3次/d与2次/d母猪的日平均采食量分别为3.33、2.41 kg,哺乳期间母猪平均总采食量前者较后者高23 kg/头;哺乳仔猪平均断奶窝重分别为32.35、29.14 kg,窝增重前者较后者高3.17 kg/窝。综上,通过增加饲喂次数和选择与人工作息时间不一致的时间点饲喂可以提高哺乳母猪的采食量,但需要智能化自动化饲喂设备相配套。The purpose of this experiment was to study the effect of different daily feeding frequency and feed to water ratio on the performance of Chinese indigenous pig in summer.In this experiment,48 lactating sows were selected,and they were randomly divided into four groups(each group including 12 sows,respectively).Experimental treatments were as follows:twice,feed:water=1∶2.5(control group);twice,feed:water=1∶3.5;three times,feed:water=1∶2.5;three times,feed:water=1∶3.5.Sow feed intake,piglet growth performance,temperature and relatively humidity were monitored in this experiment.Under this condition,data was collected from parturition to weaning.The results showed that during the lactating period,the average daily intake of lactating sows with three times per day and twice per day were 3.33 kg and 2.41 kg,respectively,the weaning weight of piglets were 32.35 kg and 29.14kg,respectively.Compared to the control group with feeding twice per day,the total feed intake of one sow in lactating period was 23 kg higher and the weaning weight of piglets was 3.17 heavier for the experimental group.If the method to improve the feed intake of lactating sows is to increase the feeding frequency during nonworking time,the intelligent and automatic equipment are needed.
