饲粮能量浓度对肥育猪行为特点的影响

采用单因子试验设计,研究不同能量浓度对肥育猪非采食期间行为的影响。选取81头年龄、体重相近的杜长大三元杂种猪,采用随机区组设计,共3个处理组,每处理组3栏,每栏9头猪,分别饲喂能蛋比相同的3种不同消化能浓度的饲粮(能蛋比均为79 MJ/kg),低能饲粮消化能10.87 MJ/kg;中能饲粮消化能12.54 MJ/kg;高能饲粮消化能14.21 MJ/kg。试验结果表明,饲喂高能饲粮的生长肥育猪行为规癖发生频率最低,趴卧时间最多(P<0.05)。

Effects of dietary energy concentrations on behavior performance in finishing pigs

In order to study the effect of different energy density on behavior performance in finishing pigs,81 Duroc×Landrace×largw cross growing finishing pigs of the average weight closely(50.01±0.96) kg at different ages were selected by using 3 treatments and each treatment contained 3 fences and each fence 9 repeats and designed by the single factorial experiment design in the present study.Feeds were separately different dgestible energy concentration at same PC/DE(PC/DE 18.9 kcal/g),the low-energy group 10.87 MJ/kg,middle-energy group 12.54 MJ/kg and high-energy group 14.21 MJ/kg.The results showed that pigs fed at the high energy had least behaviour steretypies and longest lying times(P<0.05).
