Effects of dietary carbohydrate/lipid ratios on non-specific immune responses, oxidative status and liver histology of juvenile yellow catfish Pelteobagrus fulvidraco

This study aimed to investigate the effects of dietary carbohydrate/lipid (CHO:L) ratios on immune responses, oxidative status, and liver histology of juvenile Pelteobagrus fulvidraco . Six isonitrogenous and isoenergetic diets were formulated, containing various CHO:L ratios from 1.11 to 9.50. Each diet was tested in four replicates for 8 weeks. The results indicated that the leucocyte count, plasma globulin content and lysozyme activity of fish fed the 5.58 CHO:L diet were significantly ( P P P P P
