| Abstract | ||
| An experiment was conducted to determine the effects of diet formulation based on total and digestible amino acids in feedstuff and requirement on broiler breeder towards performance and protein efficiency from 50 to 64 weeks of ages. 280 female and 40 male broiler breeder in 4 treatments with 10 replicates (7 females + one male) were used in the form of a completely randomized design. Four experimental diets were formulated based on two factors. First included two levels of Total (TAAF) and Digestible Amino Acids (DAAF) of Feedstuff and the second were two levels of Total (TAAF) and Digestible Amino Acids (DAAF) Requirements of broiler breeder. The results showed that egg weight, egg production (%), egg mass (g/hen/day), feed conversion ratio, Protein intake/egg and protein conversion ratio were significantly different which was affected by diets formulation based on amino acids of feedstuff (P<0.01). Treatment 3 (DAAF + TAAR) showed the best level which was significantly different (P<0.01) in egg weight 68.97 (g), egg production 62.45 %, egg mass 43.1 (g/hen/day), feed conversion ratio 3.59, Protein intake/egg 34.61 (g/egg) and protein conversion ratio 0.502.This experiment showed that diet formulation based on Digestible amino acids of feedstuff had significantly improved protein effeciency and performance of broiler breeder. | ||
