Abstract
- The objective of this study was to investigate the effects of selenium yeast on the growth, histomorphology, antioxidant capacity and apoptosis of largemouth bass (Micropterus salmoide). The five iso-nitrogen and iso-lipid feeds were supplemented with selenium yeast levels of 0, 0.5, 1.0, 1.5 and 2.0 mg/kg, respectively. The 525 largemouth bass (initial body weight: 11.48 ± 0.43 g) were equally divided into 15 buckets (three buckets per feed treatment) for a 67-day feeding experiment. The results showed that the addition of 1.5 and 2.0 mg/kg of selenium yeast significantly reduced weight gain rate, and specific growth rate (P 0.05). With the addition of 1.5 mg/kg of selenium yeast, the relative expression of growth hormone 1, insulin-like growth factor-1, superoxide dismutase, catalase, Kelch-like ECH-associating protein 1, and nuclear factor erythroid 2 related factor 2 in hematocyte was significantly increased (P
