摘　　要：试验以民猪和大白猪仔猪为研究对象,比较不同品种采食行为差异,分析哺乳仔猪采食行为与其生产性能关系及母猪泌乳量对仔猪采食行为的影响,以期为改进哺乳仔猪饲喂方案提供理论依据。结果表明,与大白猪仔猪相比,民猪仔猪平均每次摄食和探索时间更长,每日饮水和探索次数较低;民猪仔猪哺乳期日增重、相对生长速率与饮水和探索次数呈显著正相关(P<0.05),断奶重与摄食时间呈显著负相关(P<0.05);大白猪仔猪哺乳期日增重、相对生长速率与摄食时间、饮水次数和时间呈显著正相关,初生重与摄食次数和时间呈显著负相关(P<0.05)。民猪仔猪保育期末重与哺乳前期摄食时间呈显著负相关(P<0.05),保育期末重、日增重及相对生长速率与哺乳后期摄食次数和时间、探索时间呈显著负相关(P<0.05);大白猪仔猪保育期日增重、相对生长速率与哺乳后期摄食次数呈显著正相关(P<0.05),保育期末重与探索时间呈显著负相关(P<0.05)。低泌乳量组哺乳仔猪摄食次数和时间极显著高于高泌乳量组(P<0.01)。由此可见,民猪与大白猪哺乳仔猪在摄食、饮水、探索行为发生频次和时长上存在较大差异,且仔猪采食行为对其生长发育有显著影响,但影响方式不同;母猪泌乳量对哺乳仔猪摄食行为表现有重要影响。In order to provide theory basis for the improvement of feeding scheme of suckling piglets,the feeding behavior of the suckling piglets of Minzhu and Large White pig were investigated,and its relationships with growing performance and sows’milk-yield were analyzed in this study.The results showed that compared with Large White piglets,the durations of the ingestive and exploring of Minzhu piglets during lactation were longer,the frequencies of the drinking and exploring were fewer.During lactation,Minzhu piglets’daily gain and relative growth rate were significantly positively correlated with the frequency of drinking and exploring;weaning weight was significantly negatively correlated with the ingestive time(P<0.05).For the Large White piglets,daily gain and relative growth rate were significantly positively correlated with ingestive time,drinking time and frequency;born weight was significantly negatively correlated with ingestive time and frequency(P<0.05).Minzhu piglets’weaning weight were negatively correlated with the pre-lactation ingestive time significantly(P<0.05);the growth traits during nursery period were negatively correlated with the frequency and time of ingestive and exploring time in the post-lactation period(P<0.05);Large White piglets’daily gain and relative growth rate were positively correlated with the frequency of ingestive in the post-lactation period(P<0.05),and the weight at the end of nursery period was significantly negatively correlated with the exploring time(P<0.05).The frequency and time of ingestiveof Minzhu piglets and Large White piglets in the low milk-yield group were significantly higher than those in high milk-yield group(P<0.01).In conclusion,there were great differences in the frequency and duration of ingestive,drinking and exploring behaviors between the two breeds,and the feeding behavior of suckling piglets had a significant impact on the growing performance.The milk-yield of sows had a pivotal influence on the ingestive behavior of suckling piglets.
