Effects of sea buckthorn pomace on growth performance, serum metabolites and antioxidant indexes of growing pigs

Sea buckthorn pomace (SBP), an agro-industrial waste, containing useful nutrition compounds for animal production. This study aimed to evaluate the effect of growth performance and serum metabolisms in growing pig when consumed SBP. A total of 40 crossbred 70-day-old growing pig with initial body weight (IBW; 30 ±1.5 kg) were randomly assigned to 4 groups. The pigs were fed dietary supplementation of SBP (0.0%, 0.5, 1.5%, and 2.0 %) for 30 d. It concluded that the appropriate level of 1.5% SBP supplementation could improve pig growth performance. Serum immune and antioxidant indexes performed best in 1.5% SBP supplementation group. We suggested that the appropriate level of SBP supplementation would be 1.5% for growing pig, which could improve their growth performance, serum immune and antioxidant indexes.
