中文摘要:

本试验旨在研究生产性能测定站对猪只应激水平及采食行为的影响。选用体重为(28.2±3.41)kg的大白生长猪122头,公母各半,按圈随机分成普通料槽15头组、测定站15头组以及测定站8头组,15头组3个重复,8头组4个重复,试验期44d。试验期间,测定猪只皮肤温度和唾液皮质醇水平,并对猪只采食行为进行分析。结果表明:3个处理之间,猪只唾液皮质醇水平差异不显著。测定站显著提高了猪只第2天时的皮肤温度(P〈0.05),极显著降低了第15天的猪只皮温(P〈0.01)。测定站8头组猪只采食量略高于测定站15头组,并且30d以后猪只采食量差距呈增大趋势。测定站8头组猪只采食次数低于测定站15头组,但日累计采食时间高于测定站15头组。测定站8头组和15头组猪只在09:00、15:00以及19:00时存在采食高峰,但测定站15头组猪只日节律采食行为变化曲线较为平缓。

英文摘要:

The aim of this experiment was to study the effects of electronic feeding station on stress response and feeding behavior of growing pigs. One hundred and twenty-two Large White growing pigs with initial weight of (28. 2 ±3. 41) kg were randomly allotted into station 15 group, common silo 15 group and station 8 group by pens. The pigs were stratified by sex. The 15 groups had 3 replications, and 8 group had 4 replications. Feeding period was 44 days. During the test period, the skin temperature of pigs was tested, and the saliva was collected to determine the cortisol concentration. At the same time, the feeding behavior was analyzed. The results showed that salivary cortisol level of pigs had no significant differences between the three treat- ments. The station significantly increased the pig skin temperature (P〈0.05) on 2na day, and significantly decreased skin temperature (P〈0.01) on 15th day. Feed intake of pigs in station 8 group was slighter higher than that in station 15 group, and the gap of feed intake tended to be lager after 30 days. Intake times of pigs in station 8 group was lower than that in station 15 group, but the cumulative feeding time during a day was higher than that in station 15 group. Both station 8 and 15 group had feeding peaks at 09:00, 15:00 and 19:00,but the daily feedingbehavior curve of pigs in station 15 group was more gentle.
