Abstract：
BACKGROUND: Selenium (Se) is a rare essential element that plays a vital role in the health and performance of animals. By interfering in the production of antioxidant enzymes such as glutathione peroxidase, thioredoxin reductase and methionine sulfoxide, Se plays a role in reducing the effects of oxidative stress and animal performance.
OBJECTIVE: This study aimed to investigate the effect of hydroxy-selenomethionine (OH-SeMet) in the diet of broiler breeder and old broiler breeder roosters on productive performance, reproduction and sperm quality parameters.
METHODS: For this purpose, 260 broiler breeders of the Ross 308 strain were used in a completely randomized design with four treatments and five replications (13 hens and one rooster in each replication). Experimental treatments included: (1) a basal diet without OH-SeMet (T1:control), (2) a broiler breeder diet without OH-SeMet and a rooster diet containing 0.1 mg/kg OH-SeMet (T2), (3) broiler breeder diet containing 0.1 mg/kg OH-SeMet and rooster diet without OH-SeMet (T3) and (4) broiler breeder and rooster diet contained 0.1 mg/kg OH-SeMet (T4).
RESULTS: The results showed that T3 and T4 treatments improved egg production, egg weight, egg mass and feed conversion ratio (FCR) compared to the control treatment (p < 0.05). The fertility and hatchability percentages of T4 and T2 treatments increased compared to T1 and T3 treatments (p < 0.05). The rate of embryonic losses in T1 was higher than in other treatments. However, grade one chickens were higher in T4 than in other treatments (p < 0.05). Total motility and viability of sperms were significantly higher in T2 and T4 treatments than in T1 and T3 treatments. The sperm abnormality percentage and sperm MDA concentration decreased in T2 and T4 treatments.
CONCLUSIONS: Therefore, using OH-SeMet may be a practical approach to help old broiler breeders\' production and reproduction performance.

摘要：
背景：硒（Se）是一种稀有的必需元素，对动物的健康和性能起着至关重要的作用。通过干扰谷胱甘肽过氧化物酶等抗氧化酶的产生，硫氧还蛋白还原酶和蛋氨酸亚砜，硒在降低氧化应激和动物性能的影响中起作用。
目的：本研究旨在研究肉鸡种鸡和老肉鸡种鸡公鸡日粮中羟基硒代蛋氨酸（OH-SeMet）对生产性能的影响，繁殖和精子质量参数。
方法：为此，在完全随机设计中使用Ross308菌株的260只肉鸡饲养员，进行四次处理和五次复制（每次复制13只母鸡和一只公鸡）。实验治疗包括：（1）不含OH-SeMet的基础饮食（T1：对照），（2）不含OH-SeMet的肉鸡饲养员饮食和含0.1mg/kgOH-SeMet（T2）的公鸡饮食，（3）含有0.1mg/kgOH-SeMet的肉鸡饲粮和不含OH-SeMet的公鸡饲粮（T3）和（4）肉鸡饲粮和公鸡饲粮含有0.1mg/kgOH-SeMet（T4）。
结果：结果表明，T3和T4处理提高了产蛋量，鸡蛋重量,与对照处理相比,蛋质量和饲料转化率(FCR)(p<0.05)。与T1和T3处理相比,T4和T2处理的可育性和孵化率百分比增加(p<0.05)。T1的胚胎丢失率高于其他治疗。然而,一级鸡T4高于其他处理(p<0.05)。T2和T4处理的精子总运动能力和活力明显高于T1和T3处理。在T2和T4处理中，精子异常百分比和精子MDA浓度降低。
结论：因此，使用OH-SeMet可能是帮助老肉鸡饲养员生产和繁殖性能的一种实用方法。
