Effect of four forms of zinc on growth performance, antioxidant activity and mineral retention in juvenile hybrid grouper (Epinephelus fuscoguttatus♀×E. lanceolatu♂)

Bin YIN et al.

Compared with ZnSO4, Zn4(OH)6SO4 significantly improved the growth performance and SOD activity in the liver of the juvenile groupers; Zn-Gly and Zn-MHA significantly improved the growth performance of the juvenile groupers, reduced the content of malondialdehyde in the liver, increased the height of the foregut folds and promoted the intestinal development. The bioavailability of Zn4(OH)6SO4, Zn-Gly and Zn-MHA relative to ZnSo4 were 119, 118 and 122%, respectively, for weight gain ratio (WGR), and were 111, 114 and 131%, respectively, for CuZn-SOD activity. In overall, Zn-MHA is the best Zn source among the four forms of zinc in promoting growth, feed conversion and survival rate, therefore, is high beneficial in aquaculture.
