Bertalanffy Model Reflects Growth Trajectory in Aseel Chicken

Aseel, a popular breed of native chicken, characterized by its pugnacity, fighting strength and royal gait is being used to create crosses for domestic chicken production. However, information on growth models scanty. An experiment was conducted evaluate different non-linear find out best fitting model in maintained at Central Avian Research Institute, Izatnagar, Bareilly. Data body weights from 12-weeks age 20-weeks biweekly intervals were recorded random bred single-hatched flock. Owing the characteristic growth, three namely, Gompertz, Bertalanffy Logistic evaluated. Goodness fit all checked using coefficient determination (R2), adjusted (Adj-R2), mean square error (MSE), absolute (MAE) Akaike criterion (AIC). The most accurately trend males, females pooled sex data. study revealed that this may be ascertain average Aseel under mating. investigation has generated baseline data modelling groups similar investigations other breeds.
