Effects of Dietary Protein-to-Energy Ratios on Growth, Immune Response, Antioxidative Capacity, Liver and Intestinal Histology, and Growth-Related Gene Expression in Hybrid Yellow Catfish (Pelteobagrus fulvidraco × Pelteobagrus vachelli )

Table 4

Body condition indices of hybrid yellow catfish fed different dietary P/E ratios for 7 weeks.

P/E ratio mg/kcal	CF^1	VSI^2	HSI^3	IPF^4
84		^c	^b	^c
88		^c	^b	^c
90		^bc	^ab	^bc
93		^ab	^ab	^ab
95		^bc	^ab	^bc
96		^ab	^b	^ab
99		^ab	^ab	^ab
103		^a	^a	^a

Values are of three replications. Values in the same line with superscripts are significantly different (). CF¹: condition factor; VSI²: viscerosomatic index; HSI³: hepatosomatic index; IPF⁴: intraperitoneal fat ratio.
