Utilisation of ambadi (hibiscus cannabinus) meal by growing chickens

Abstract

Abstract 1. Experiments were conducted to compare the utilisation of ambadi meal with that of peanut meal in WL chicks and broilers. 2. Ambadi meal, either expeller‐processed (135.5 g and 271 g/kg) or solvent‐extracted (130.5 g and 261 g/kg), was incorporated at the expense of the peanut meal protein used in the reference diet (180 g/ kg) into diets which were fed to WL pullets (experiment 1) from 1 to 56 d of age. The weight gains and food efficiencies of the chicks fed on the ambadi meal and reference diets were similar. 3. With broilers (experiment 2) the weight gains were also similar, at all dietary concentrations of ambadi meal (89 to 356 g/kg), to those on the reference diet (235 g/kg peanut meal) from 14 to 35 d of age. However, food intake was higher on the ambadi meal diets and this resulted in significantly poorer food efficiency when compared to the reference diet. 4. High food intake and consequently low food efficiency was still evident in birds given ambadi meal diets even when ambadi meal ...
