Comparison predicted using nonlinear model and in vivo studies growth production of broiler after fed different levels of fermented tamarind flour as replacing soya bean meal

Abstract

This study compared two nonlinear models for growth performance of broiler after fed different levels of fermented tamarind flour as replacing soya bean meal. Two experiments were designed for this purpose. In first experiment, 20 chickens (Lohmann MB202) that had been fed on the different level of tamarind flour and weighed to determine best model suitable. In second experiment the treatment of the study was basal feed (control): basal feed substitute soy bean meal with tamarind flour 25%: basal feed substitute soy bean meal with tamarind flour 50%: basal feed substitute soy bean meal with tamarind flour 100%. The results showed that the used of tamarind flour did not give a significant effect (p > 0.05) on the production performance. It concluded the comparison of growth models in terms of goodness revealed that gompertz is the most appropriate model for describing between age and body weight in this experiment.
