Effect of Nano-Selenium on Growth Performance, Meat Quality and Antioxidant Capacity of Finishing Pigs
Abstract：To investigate the effects of nano-selenium on the growth performance, meat quality, and blood antioxidant capacity of finishing pigs, 128 finishing pigs with body weight of 70-75 kg were selected. The pigs were randomly divided into four groups, with each group having four replicates and eight pigs per replicate. The control group was fed a basal diet, while the experimental groups 1, 2, and 3 were fed diets supplemented with 0.3, 0.5, and 0.7 mg/kg of nano-selenium, respectively. The results showed that adding 0.5 and 0.7 mg/kg of nano-selenium significantly reduced the feed-to-gain ratio and the 24-hour drip loss of the carcass (P < 0.05). Nano-selenium also significantly improved the blood antioxidant capacity indicators (P < 0.05). The study demonstrated that adding nano-selenium had a positive effect on the growth performance, meat quality, and blood antioxidant capacity of finishing pigs, with an appropriate addition level of 0.5 mg/kg.
