چکیده:

The present trial was conducted to investigate the effect of grape pomace on perf01mance in broiler chicks. A total of 450 day-old mixed sex broiler chicks (Ross 308) were randomly allotted to 6 dietaty treatments with 5 replicates of 15 birds in a completely randomized design. Dietary treatments consisted of a control diet and diets contain in 3, 6, 9, 12 and 15% grape pomace which fed during a 39 d trial period. Average daily feed intake (ADFI), average daily gain (ADG) and feed conversion ratio (FCR) were measmed dming starter (10-25 d), grower (25- 36 d) and fmisher (36-49 d) phases. Results of this study indicated that experimental treatments had significant effect on ADFI of broiler chickens in statter phase (P<0.05). In this regard, there were no significant differences between birds fed control diet and birds fed diets supplemented with grapepomace. Also Dietary inclusion of 3% grape pomace was shown too resulted in the highest (P<0.01) da.ily gain statter (10-25 d) trial period. Experimental treatments had significant effect on FCR of broiler chickens in starter, grower (p<0.01), fmisher (P<0.05) and during trial period (p<0.001) phases. The best FCR was obsetved for treatment containing 3% grape pomace and control. From the present results, it seems that dietaty utilization of grape pomace could improve growth performance and feed efficiency
