摘要
为研究夏季高温猪肥育期饲喂鲜绿车前草对生长性能的影响，采用单因子随机区组试验设计，选取320头平均体重（59.78±1.38） kg杜长大肥育猪，随机分为4组，每组10个重复，每个重复8头猪。肥育猪基础饲粮按60～90 kg营养需求结合夏季高温实际生产情况配制。对照组饲喂猪肥育期基础饲粮，4%车前草组采取96%基础饲粮＋4%车前草（按风干量计）饲喂方式，8%车前草组采取92%基础饲粮＋8%车前草（按风干量计）饲喂方式，12%车前草组采取88%基础饲粮＋12%车前草（按风干量计）饲喂方式。预试期7 d，正试期50 d。结果显示，在夏季高温条件下，猪肥育期增重以添加8%车前草组效果最好，与4%车前草组和12%车前草组相比分别显著和极显著增加5.96%和11.06%，极显著高于对照组12.53%；日采食量，8%车前草组显著高于其他组（P＜0.05），其与对照组相比显著提高8.68%（P＜0.05）；料重比，8%车前草组最低，饲料转化率最佳，分别极显著低于对照组和12%车前草组3.47%和2.86%，比4%车前草组低1.29%，但差异不显著。试验表明，在夏季高温情况下，猪肥育阶段添加鲜绿车前草替代基础饲粮比例达到8%（风干量计）时，猪的采食量、料重比和增重性能显著或极显著改善，并达到最佳生长水平，综合效益最好。
For the study of effect of fresh green herba plantaginis on production performance of flattening pigs in the summer,this test adopts single factor randomized block design which were selected 320 heads healthy DLY flattening pigs of the similar weight （59.78 ±1.38） kg.The pigs were divided into 4 groups randomly,each group of 10 repeats and each repeat of 8 pigs.The basal diet of fatteninig pigs was conconted of 60～90 kg nutri-tional needs which combined with practical production situation of high temperature in summer.The control group was fed the basal diet,the test group 1 was fed the diet of 96% basal diet add to 4% fresh green herba plantagins（dry meter,the same below）,the test group 2 was fed diet of 92%basal diet add to 8%fresh green her-ba plantagins,the test group 3 was fed the diet of 88% basal diet add to 12% fresh green herba plantagins.For-mal test period was 50 days.Test results show that under the condition of high temperature in summer,the 8%plantain group get the highest weight gain which was increased 5.96%（P〈0.05） significantly and 11.06%（P〈0.01） extremely significantly compared with the 4% plantain group and the 12% plantain group,were higher than the control group 12.53%（P〈0.01） significantly;feed intake level of 8% plantain group was higher than the other groups（P〈0.05） significantly which was higher than the control group 8.68%（P〈0.05） significantly;the feed weight ratio of 8% plantain group was minimum which was extremely significantly lower than the control group and 12%plantain group 3.47%（P〈0.01） and 2.86%（P〈0.01）,lower than 4%plantain group 1.29%（P＆gt;0.05）.The experi-ments show that under the condition of high temperature in summer,the fattening pig adding 8% fresh green plantain improved feed intake,feed ratio and weight increase performance significantly or very significantly,and achieve the best growth level.
