This study aimed to investigate the effect of the fermented soybean meal on the reproductive performance, oxidative stress and colostrum composition of sows, and the growth performance of their progeny. A total of 44 sows were allotted to four dietary groups ( = 11/group). The dietary groups included the basal diet group (control) and the treatment groups in which soybean meal in the basal diet was replaced with 2%, 4%, and 6% fermented soybean meal, respectively. The experimental diets were fed to the sows from the 78th day of gestation to the 21st day of lactation. Replacing soybean meal in the basal maternal diet with the fermented soybean meal decreased the levels of malondialdehyde, cortisol, and 8-iso-prostaglandinF2α in the serum of sows and increased the average weight of piglets on the 14th day and the 21st day after birth. The activity of superoxide dismutase in the serum of sows was increased in the group with 4% fermented soybean meal on the 17th day of lactation. The levels of estrogen and growth factors in the serum of sows were enhanced in the group with 6% fermented soybean meal. In the colostrum, the levels of the protein and the immunoglobulin G were enhanced in the group with 4% fermented soybean meal. In conclusion, replacing the soybean meal in the basal maternal diet with the fermented soybean meal attenuates the oxidative stress status of the gestational and lactational sows, and enhances the average weight of their offspring.
本研究旨在探讨发酵豆粕对母猪繁殖性能、氧化应激和初乳成分及其后代生长性能的影响。总共44头母猪被分配到四个日粮组（每组n = 11）。日粮组包括基础日粮组（对照组）和处理组，其中基础日粮中的豆粕分别被2%、4%和6%的发酵豆粕替代。从妊娠第78天到泌乳第21天给母猪饲喂实验日粮。用发酵豆粕替代基础日粮中的豆粕可降低母猪血清中丙二醛、皮质醇和8-异前列腺素F2α的水平，并增加出生后第14天和第21天仔猪的平均体重。在泌乳第17天，4%发酵豆粕组母猪血清中超氧化物歧化酶的活性增加。6%发酵豆粕组母猪血清中雌激素和生长因子的水平升高。在初乳中，4%发酵豆粕组蛋白质和免疫球蛋白G的水平升高。总之，用发酵豆粕替代基础日粮中的豆粕可减轻妊娠和泌乳母猪的氧化应激状态，并提高其后代的平均体重。
