“佳力康”对围产和泌乳期母猪生产性能影响的试验研究

Effects of "Jialikang" on Production Performance of Parturition and Lactation Sows

为研究"佳力康"对母猪生产性能及健康的影响,选择正常妊娠的第3胎次大白母猪60头,随机分成3组,每组20头,对照组饲喂基础饲粮,试验1组从产前7 d至断奶在基础饲粮中添加"佳力康",每头每天1次,每次5 g,试验2组从产前25 d至断奶在基础饲粮中添加"佳力康",每头每天1次,每次5 g;其它饲养管理与对照组一致,试验至母猪断奶后14 d结束。结果表明:1)母猪繁殖与健康方面,与对照组相比,试验1组和2组母猪平均窝产活仔数分别提高0.24、0.60头,分娩早产率分别降低5和15个百分点,滞产率分别降低5和10个百分点,哺乳期三联征发病率两组均降低10个百分点;泌乳力和泌乳质量均有改善提高的趋势,其中,试验1组和2组母猪初乳中乳蛋白分别提高9.22%(P>0.05)和26.77%(P<0.05)、乳糖提高10.70%(P>0.05)和13.58%(P<0.05)、乳脂提高33.42%(P<0.05)和48.64%(P<0.05);试验1组和2组母猪断奶体况评分分别提高24.12%(P<0.05)和18.68%(P<0.05),断奶后14 d内发情率分别提高5和10个百分点,总受胎率均提高10个百分点。2)仔猪生长与健康方面,与对照组相比,试验1组和2组哺乳仔猪25 d断奶窝重分别提高6.99%(P>0.05)和12.82%(P<0.05)、平均日增重分别提高1.34%(P>0.05)和5.75%(P<0.05);腹泻发病率分别降低3.92和4.27个百分点、成活率分别提高3.87和2.61个百分点。研究证明,母猪围产期和泌乳期饲喂"佳力康",能够有效促进母猪的免疫和生殖机能,改善母猪健康和繁殖性能,并间接提高了哺乳仔猪的生长性能和健康状况。综合比较,试验2组的效果更为明显。

In order to study the effects of ＂Jialikang＂ feed supplementation on production performance of parturition and lactation sows, 60 Large White sows （the third parity） were randomly divided into 3 groups equally, which were fed the same basal diet. The test group 1 and test group 2 were added 5 g/d of ＂Jialikang＂ from 7 d pre-farrowing to weaning and from 25 d pre-farrowing to weaning, respectively. The productive performances of 3 groups were tracked to measure. The results showed as follows： 1） Compared with the control group, the test group 1 and 2 were increased 0.24 and 0.60 in the average number born alive, decreased 5 and 15 percent points in the farrowing ahead, decreased 5 and 10 percent points in the farrowing delay, decreased 10 and 10 percent points in the incidence of MMA during lactation, respectively. The test group 1 and 2 were higher 9.22%（P〉0.05） and 26.77%（P〈0.05） in colostrnm protein, 10.70%（P〉0.05） and 13.58%（P〈0.05） in lactose, 33.42%（P〈0.05） and 48.64% （P〈0.05） in fat content, respectively. The test group 1 and 2 were higher 24.12%（P〈0.05） and 18.68%（P〈0.05） in weaned sows body condition score, higher 5 and 10 percent points in 14 d oestrus rate, higher 10 and 10 percent points in conception rate than the control group, respectively.2） The piglets of test group 1 and 2 were higher 6.99% （P〉0.05） and 12.82% （P〈0.05） in weaned litter weight at 25 d, higher 1.34% （P〉0.05） and 5.75% （P〈0.05） in ADG, lower 3.92 and 4.27 percent points in diarrhea rate, and higher 3.87 and 2.61 percent points in survival rate than that of the control group, respectively. The results proved that ＂Jialikang＂ have great effects on promoting sows immune and reproduction function, and indirectly improving piglets growth and health performance. The eompositive effect of the test group 2 is better than that of the test group 1.
