Comparison of Reference Tables of Feed stuffs Analysis in Broilers Feed Formulation.

This experiment was conducted to determine the effect of nutrient analysis tables of ingredient on Ross strain broiler performance. This experiment used CRD design. Chicks were grouped in to three treatments with six replications and each with 15 chicks. The experimental treatment consisted: 1) Diet formulation according to analysis table of NRC. 2) Diet formulation according to analysis table of FEEDSTUFF and 3) Diet formulation according to analysis table of DEGUSSA. Feed intake (FI), Average daily gain (ADG), Feed conversion ratio (FCR) and Production index (PI) were measured. The cost of feed per lkg of weight and carcass characteristics were also compared. According to the result the body weight among different treatments was significant (p<0.05).The highest final weight was obtained with NRC analysis table. Feed intake among treatments was not significantly difference (p>0.05). There was significant difference in feed conversion among treatments and NRC analysis table was resulted the lowest FCR. Production index among treatments was significantly difference (p<0.05). The cost of feed per lkg weight among treatment was not significant (p>0.05).Finally, with respect of all parameters, the best treatment was NRC analysis table.
