Grape seed tannin extract (GPE) from wine grape pomace has many effective anti-oxidative effects and is used as a promising natural feed additive in the animal feed industry. This study investigated the effect of GPE as a source of tannin on the antioxidant capacity and testis development in Hu lambs. Twenty-seven 3-month-old ram lambs were randomly assigned to three groups. For each treatment group, nine lambs were allocated to nine pens (one lamb per pen). The lambs in the control group were fed a control diet without GPE for 61 day
