Abstract

This experiment was conducted in order to investigate the regression between different levels of diet nutrients in grower period on performance and CARCASS CHARACTERISTICS of BROILER chicks. The chickens were fed the same diet in starter period, later four diet with different levels of nutrients were used in grower period. The level of metabolism energy (ME) was 3000, 3100, 3200 and 3300 kcal/kg. Diets used in the research are set according to NRC (1994). Furthermore, the ratio all nutrients to energy were kept constant. The results showed that WEIGHT GAIN, feed conversation ratio and CARCASS CHARACTERISTICS were affected by different levels of nutrients. In addition, an increase in density of nutrients had a direct correlation with gain weight, and a reverse one with feed and carcass percentage. Finally, analysis of regression between carcass and nutrients density indicated that there were a correlation between nutrients density changes and carcass with increasing levels of nutrients. In other words, carcass% (r2=97%), edible carcass% (r2=95%), thigh% (r2=92%) and relative weight of gizzard (r2=91%) showed the highest regression. Feed cost per kg meat decreased with lowest energy level (p<0.05). As a result in BROILER diets the using of low density nutrients can be useful than high density nutrients.
