摘要/Abstract

摘要： 本试验旨在研究生产性能测定站对猪生产性能和行为的影响。选用平均体重为28.2 kg的大白猪122头,公、母各半,按圈随机分成3组,分别为试验1组(普通料槽15头组)、试验2组(测定站15头组)及试验3组(测定站8头组),试验1、2组各3个重复,试验3组4个重复,试验期44 d。试验前对测定站精准性进行评价;试验期间测定猪生产性能和皮肤损伤,并对猪行为进行录像。结果表明,测定站料槽和体重称量秤精准性符合其技术参数;3组之间猪生产性能均无显著差异(P>0.05),试验3组猪的末重变异系数呈下降趋势(44.48%),试验1组猪的末重、平均日增重和平均日采食量略高于试验2组;测定站极显著增加了猪的皮肤损伤评分(P<0.01),极显著增加了试验2组第1天时的攻击行为(P<0.01),极显著降低了第7天的攻击行为(P<0.01),但采食猪所占比例相对较低,试验2组显著(P<0.05)或极显著(P<0.01)提高了猪的圈友操纵行为。

Abstract: This experiment was conducted to study the effects of electronic feeding station on growth performance and behavior in growing pigs. One hundred and twenty-two Large White growing pigs with initial weight of 28.2 kg were randomly allotted into 3 groups, experiment group 1(general 15 head groups), experiment group 2(station 15 head group) and experiment group 3 (station 8 head group) by pens. The experiment 1 and 2 groups had 3 replications respectively, and experiment 3 had 4 replications. The pigs were stratified by sex. Feeding period was 44 days. Before the test, the accuracy of the station was evaluated. During the experiment, growing performance and skin lesion were tested, and pigs' behavior was recorded. The results showed that the accuracy of the station trough and weight weighing scale met its technical parameters. The performance of pigs had no significant difference in three groups(P>0.05). The coefficient of variation (CV) of experiment group 3 final weight decreased by 44.48%. The final weight, average daily gain (ADG) and average daily feed intake (ADFI) of experiment group 1 were slightly higher than experiment group 2. The electronic feeding station highly significantly increased pigs' skin lesion(P<0.01). Experiment group 1 highly significantly increased the aggression behavior on 1st day (P<0.01), and highly significantly decreased the aggression behavior on 7th day (P<0.01). Feeding behavior of experiment group 2 was relatively lower. The electronic feeding station significantly(P<0.05) or highly significantly (P<0.01) increased pigs' pen mate manipulations.

Key words: electronic feeding station; growing pigs; growth performance; behavior
