Estimating the growth and feed consumption curve of broilers ROSS 308 during the rearing weeks

Abstract

      The study was conducted in the field of department of Animal production – Diyala university for the period 1/11/2021 – 12/2/2022. Aimed this  study the estimation The growth curve of the offspring was estimated according to the linear and nonlinear growth curve of the square and cubic model and it was noted that the cubic model was the best in predicting body weight , as the coefficient of determination amount 0.974,0.998,and 1.00 for each of the linear , square and cubic models, respectively and the cubic model recorded most accurate in predicting the amount of feed conversion for the offspring was the length of the rearing period of 6 weeks and the coefficient of determination was 0.989, 0.991 and 1.00for each of the linear , square and cubic models respectively.
