| 摘 要： | 为研究夏季热应激情况下使用全脂膨化菜籽配制哺乳母猪饲粮对其生产性能的影响，选择妊娠107 d不同胎次的长大母猪30头，采用随机区组设计分为3组，每组10头母猪，分别接受3种饲粮处理：即试验1组（5.63%膨化菜籽）、试验2组（9%膨化菜籽）、对照组（2%猪油＋5%膨化大豆）。结果表明，母猪哺乳期第18至第22天日采食量，试验1组和试验2组分别比对照组提高0.90和0.38 kg；哺乳期第18至第22天日采食量峰值，试验1组和试验2组分别比对照组提高0.64和0.23 kg；日采食量达到峰值后下降速度，试验1组和试验2组分别比对照组低50%和42.5%。试验1组、试验2组和对照组母猪失重率均较小，分别为3.10%、5.90%、4.63%；母猪断奶后1周内全部发情。哺乳仔猪窝增重，试验1组和试验2组分别比对照组提高0.65、0.75 kg。哺乳仔猪18日龄以前没有出现腹泻，19～22日龄出现轻微腹泻，且腹泻率很低。乳品质，试验1组和试验2组优于对照组；血液生理生化指标，3组均在正常范围内。说明使用全脂膨化菜籽配制的哺乳母猪饲粮适口性好，能显著增加热应激情况下哺乳母猪的采食量，改善乳品质，提高其生产性能，效果优于添加猪油＋膨化大豆的饲粮。

| Abstract: | In order to study the effect of f ull-fat expanded rapeseed on growth performance in lactation sows in the summer heat stress cases,thirty pregnancy sows of different tire107 d were randomly allotted to 3 treatments for 10 sows each,each group was fed different diet.The control group was fed based diet supplemented with 2.0%lard and 5.0% extruded soybean,experiment 1 and experiment 2 group was fed based diet supplemented with 5.63% and 9% expanded rapeseed each other.The results of rearing trial showed that：the expanded rapeseed group compared with the control group,significantly （P＆lt;0.05） increased average daily feed intake 0.90 and 0.38 kg during the sow lactation 18 to 22 days;lactation 18 to 22 d feed intake peak,experiment group 1 and 2 groups, respectively,compared with the control group increased by 0.64 and 0.23 kg;daily feed intake after reaching peak decline speed,experiment group 1 and 2 groups were 50% and 42.5% lower than the control group.Experiment 1 group,2 group and the control group sow weightlessness rate are smaller,are 3.10%,5.90% and 4.63%respectively;the sow all within 1 week after weaning estrus.Lactation piglet nest weight,experiment group 1 and 2 group than control group increased by 0.65 and 0.75 kg respectively.Lactation piglet 18 days of age before,no diarrhea,mild diarrhea,19~22 age and diarrhea rate is very low.Dairy quality,experiment group 1 and 2 group is better than the control group;blood physiological and biochemical indexes,3 groups were within the normal range. Use full-fat expanded rapeseed preparation of nursing sow good diets palatability,could significantly increase milking sow feed intake,improve milk quality,improve the growth performance in lactation sows in the summer heat stress cases,the effect is better than that of adding lard＋puffing of soybean diets. |
