Abstract：
BACKGROUND: The metabolic impacts of including soya meal, wheat gluten and corn gluten in the diet of male lambs could influence their reproductive performance.
OBJECTIVE: An experiment was carried out to assess the effects of corn gluten, wheat gluten and soya meal on the reproductive system of male lambs.
METHODS: Twenty-four male Morkaraman lambs, aged 9 months, were utilized in this study and were fed experimental diets for 56 days. The lambs were divided into a control group (soybean meal + safflower meal), a corn group (corn gluten) and a wheat group (wheat gluten).
RESULTS: The serum follicle-stimulating hormone level of the control group was significantly higher and tumour necrosis factor-alpha (TNF-α) level was lower than the wheat and corn gluten groups (p < 0.05). The lowest malondialdehyde level in testicular tissue was observed in the control group, whereas the highest was in the wheat gluten group (p < 0.05). The glutathione level in the control group was significantly higher than in the other groups (p < 0.05). The corn gluten group showed the highest CHOP and IRE1 levels; the lowest Bcl-2 levels and the highest IL-1B and P2 × 7R levels were found in the wheat group; and the lowest TNF-α levels were in the control group (p < 0.05). Additionally, the study revealed that diet had a significant impact on spermatological parameters of the testis such as diameter, volume and weight (p < 0.05).
CONCLUSIONS: These results concluded that the inclusion of different protein sources in the diet of reproductive male lambs affects the metabolism of testicular tissue.

摘要：
背景：包括豆粕在内的代谢影响，雄性羔羊日粮中的小麦面筋和玉米面筋会影响其繁殖性能。
目的：进行了一项实验以评估玉米麸质的作用，小麦面筋和豆粕对雄性羔羊生殖系统的影响。
方法：二十四只雄性Morkaraman羔羊，9个月大,在这项研究中使用，并喂食实验饮食56天。将羔羊分成对照组(豆粕+红花粉),玉米组(玉米麸质)和小麦组(小麦麸质)。
结果：对照组血清卵泡刺激素水平明显高于小麦组和玉米蛋白组，肿瘤坏死因子-α（TNF-α）水平低于小麦组和玉米蛋白组（p<0.05）。对照组睾丸组织丙二醛水平最低,而最高的是小麦面筋组(p<0.05)。对照组的谷胱甘肽水平明显高于其他组（p<0.05）。玉米麸质组CHOP和IRE1水平最高；小麦组Bcl-2水平最低，IL-1B和P2×7R水平最高；对照组TNF-α水平最低（p<0.05）。此外,研究表明，饮食对睾丸的精子参数有显著影响，如直径，体积和重量（p<0.05）。
结论：这些结果得出结论，在生殖雄性羔羊的饮食中包含不同的蛋白质来源会影响睾丸组织的代谢。
