摘要
本试验旨在研究妊娠后期和泌乳期饲粮添加姜粉对母猪和哺乳仔猪抗氧化性能的影响。试验采用2×2析因试验设计,分2个饲养阶段(妊娠后期和泌乳期)进行,每个饲养阶段设2个姜粉添加水平(0、1.0%)。结果表明,在妊娠后期饲粮中添加姜粉,显著提高了母猪血清中超氧化物歧化酶(SOD)活性、总抗氧化能力(T-AOC)和谷胱甘肽(GSH)含量,降低了母猪血清中丙二醛(MDA)含量(P<0.05);在泌乳期饲粮中添加姜粉,显著提高了母猪血清和乳中SOD活性、T-AOC和GSH含量(P<0.05);而在妊娠后期和泌乳期饲粮中分别单独添加姜粉时,均显著提高了仔猪血清GSH含量(P<0.05)。2个时期均添加姜粉对母猪血清、母乳和仔猪血清抗氧化效果最佳。由此可见,在妊娠后期和泌乳期饲粮中添加1.0%姜粉均能够提高母猪和哺乳仔猪的抗氧化性能,且2个阶段不存在交互作用,在妊娠后期和泌乳期同时添加时效果最好。
This experiment was conducted to study the effects of dietary ginger powder on antioxidant property of sows and suckling piglets during late gestation and lactation. A 2×2 factorial design was used in this experiment, and setting two feeding periods （ late gestation and lactation） , each feeding period had two ginger powder supplemental levels （0 and 1.0%）. The results show that dietary supplemented with ginger powder at late gestation significantly increased superoxide dismutase （ SOD ） activity, total antioxidant capacity （ T-AOC ） and glutathion （ GSH） content in serum of sows （ P〈0.05） , and significantly decreased serum malonaldehyde （ MDA） content （ P〈0.05） . Dietary supplemented with ginger powder at lactation significantly increased SOD activity, T-AOC and GSH content in serum and milk （ P〈0.05） . Dietary supplemented with ginger powder at late gestation and lactation significantly increased serum GSH content of piglets （ P〈0.05） . Dietary supplemen-ted with ginger powder at late gestation and lactation had the best effect on antioxidant property in serum and milk of sows and serum of suckling piglets. In conclusion, dietary supplemented with 1.0% ginger powder at late gestation and lactation can improve antioxidant property of sows and suckling piglets, and there is no interaction between late gestation and lactation, the best effect is supplementation during late gestation and lactation diets at the same time.
