Growth performance, carcass traits and economics of broiler chickens as affected by dietary sunflower meal

الملخص EN

An experiment was conducted with ١٢٠ unsexed one week old broiler (Hubbard) chicks to evaluate the effect of different levels of sunflower seed meal (SFM) on growth performance, carcass traits and economic feasebility in broiler chickens.

The experimental diets consisted of four levels of SFM: ٠% (control), ٢٥, ٥٠ and ٧٥% instead of soybean meal (SBM) in a completely randomized design.

Each dietary treatment was assigned to five replicate groups and the experiment lasted ٥ weeks (١-٦ weeks of age).

The obtained results can be summarized as follow: live body weight, body weight gain and feed conversion ratio were significantly (P٠.٠٥) affected by feeding on the SFM diets.

Economic efficiency during the experiment was improved by ٦٠.٣١, ٧٤.٦٠ and ٤٤.٤٤% for diets containing ٢٥, ٥٠ and ٧٥% SFM, respectively as compared with control diet.

It could be concluded that increasing SFM inclusion level in the diet up to ٥٠% replacing SBM improved the growth performance, feed utilization and economics of broiler chickens.
