objective: this study was conducted to evaluate the effects of different proportions of marshmallow extract (althaea officinalis l.) on growth performance and carcass composition of common carp (cyprinus carpio). methods: common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (a. officinalis) extract 0.25%, 0.50 and 1%, and with no...

this study was undertaken to evaluate the effect of hydrolysable tannin (ht) and condensed tannin (ct) on growth performance and body composition of nile tilapia. hydrolysable tannin and ct were included into diets at four levels (0, 5, 15, and 25 g kg-1 diet). the diet with zero tannin level acted as control and the response of fish fed diets containing tannin was compared to that of the contr...
