Growth, body composition, mineralisation and Na+/K+-ATPase activity of fingerling Heteropneustes fossilis (Bloch) fed diets with different levels of potassium.
Arch Anim Nutr 2019; 73(6):505-516AA

Abstract

A growth trial was performed to optimise the inclusion of potassium (K) in feeds of Heteropneustes fossilis (body weight [BW] 6.92 ± 0.1 g). Eight isonitrogenous and isoenergetic diets with varying dietary K levels were prepared by supplementing 0, 1.91, 3.82, 5.73, 7.64, 9.55, 11.46 and 13.37 g KCl/kg basal diet. Analysed dietary K levels were 0.16, 1.12, 2.08, 3.19, 4.18, 5.16, 6.11, 7.14 and 8.16 g/kg dry matter. BW gain, feed conversion ratio (FCR), protein gain (PG) and gill Na+/K+-ATPase activity were best in fish fed 4.18 g K/kg diet. The K concentrations in the whole body and vertebrae increased linearly with the increase up to 5.16 g K/kg diet and reached then a plateau. The K-retention [%] was highest in fish fed the basal diet and decreased with the further inclusion of dietary K up to 2.08 g/kg followed by no change up to diet containing 4.18 g K/kg and then declined further in fish fed higher levels of dietary K. Serum alkaline phosphatase activity was found to increase up to 4.18 g K/kg diet. Regression of BW gain, PG, gill Na+/K+-ATPase and vertebrae K concentration against varying levels of dietary K using broken-line model indicated that an inclusion of 5.44 g K/kg diet is the optimum for maximising growth and mineralisation of H. fossilis.
