大豆皮在繁育母猪生产中的应用研究
|
摘要
为研究妊娠母猪日粮中不同含量大豆皮的饲喂效果,将36头妊娠经产大白母猪随机分为4组(对照组和试验1组、试验2组、试验3组),在基础日粮中添加不同含量的大豆皮(0、4%、8%、12%),探讨大豆皮对母猪繁育性能的影响。结果表明,各组母猪在哺乳期间的平均采食量差异均不显著(P>0.05);试验1组和试验2组能显著改善母猪的繁殖性能,以试验2组母猪的繁殖性能最佳、维持背膘厚度和体质量的效果最好。与对照组相比,试验2组母猪的窝均产仔数提高0.7头,窝均初生质量提高0.83 kg,断奶存活率提高2.33个百分点,窝均断奶质量提高12 kg,发情间隔缩短2 d,哺乳期背膘厚度下降5.0 mm,整个繁育周期平均体质量下降12 kg。因此,建议在妊娠母猪日粮中添加大豆皮的量为8%。
To investigate the feeding effect of dietary supplementation of soybean hull on breeding sows, a total of 36 multiparous and pregnant sows were randomly allocated to four groups: three experimental groups with dietary supplementation of soybean hull at 4%(experimental group 1), 8%(experimental group 2) or 12%(experimental group 3) and one control group without soybean hull supplementation. The indicators associated with reproductive and productive performance of the experimental breeding sows were statistically evaluated. The results showed that no statistical difference in average feed intake was observed between various groups during the lactation period(P>0.05); the reproductive performance was found significantly improved in experimental group 1 and experimental group 2 compared to the control group, and the experimental group 2 performed best in reproductive performance, backfat thickness and body weight. Compared to the control group, the average litter size, average litter birth weight, weaning survival rate, and average litter weaning weight of experimental group 2 were increased by 0.7, 0.83 kg,2.33%, and 12 kg, respectively, and the inter oestrual period, backfat thickness during the lactation period, and average weight over the whole reproductive cycle were reduced by 2 days, 5.0 mm, and 12 kg. Our results suggest that the optimal dietary supplementation level of soybean hull to pregnant sows is 8%.
