摘要: The objective of this work was to study growth and body nutrient deposition profiles male female Cobb Ross broilers using Gompertz equations. A total number 1,920 one- 56-day-old were used. randomized experimental design in a factorial arrangement (2 strains x 2 sex), with 4 replicates 120 birds each, applied. Diets formulated supply the requirements recommended by genetic companies. sample weekly weighed sacrificed after 24 hours fasting. Carcasses defeathered again. parameters equation for weight its components (water, ashes, protein, fat) estimated. An interaction (p<0.05) between sex breed observed mature (Wm) (kg), rate (b) (daily) time at maximum (t*) (day) weight, water ash. presented earlier protein ash deposition. strain superior
