Abstract：
Soybean is an important source of high-quality vegetable protein with various health-improving properties, and its main bioactive substances are small peptides produced by in vitro enzymatic hydrolytic processes. In traditional layer breeding, the nutritional health of roosters is frequently neglected, ultimately affecting the quality and quantity of offspring. This study investigated the effects of various quantities (0%, 0.15%, 0.30%, 0.45%, and 0.60%) of soybean bioactive peptide (SBP) feed additives on immunological and antioxidant functions, gut health, and reproductive performance of roosters. SBP supplementation significantly improved male growth and reproductive performance, including growth rate, feed conversion ratio, reproductive organ development, and semen quality. SBP also increased immune and antioxidant levels, boosted the integrity of the small intestinal physiological structure and barrier function, and diversity of cecal microbes, and decreased the apoptotic ratio of small intestinal epithelial cells. The effects of SBP on various functions of males showed a quadratic trend, with the optimal concentration determined to be 0.45%.
摘要：
大豆是优质植物蛋白的重要来源,具有多种保健功效,其主要生物活性物质是通过体外酶解过程产生的小肽。在传统的蛋鸡养殖中,公鸡的营养健康经常被忽视，最终影响后代的质量和数量。本研究调查了各种量的影响(0%，0.15%,0.30%,0.45%,和0.60%)的大豆生物活性肽(SBP)饲料添加剂对免疫和抗氧化功能的影响,肠道健康，和公鸡的繁殖性能。SBP补充显着改善了男性的生长和繁殖性能，包括增长率，饲料转化率，生殖器官发育,和精液质量。SBP还增加了免疫和抗氧化水平，增强了小肠生理结构和屏障功能的完整性，盲肠微生物的多样性，并降低小肠上皮细胞的凋亡率。SBP对男性各种功能的影响呈二次趋势，最佳浓度为0.45%。
