Popis: 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. Objectives 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
