Title

EFFECTS OF DIETARY SUPPLEMENTAL GUANIDINOACETIC ACID AND BETAINE ON PERFORMANCE, CARCASS CHARACTERISTICS, MEAT QUALITY AND THYROIDS HORMONE OF BROILERS SUBJECTED TO COLD STRESS

Pages

Abstract

 This study was conducted to determine the effects of dietary supplemental guanidinoacetic acid and BETAINE on performance, carcass characteristics, meat quality and thyroid hormones of BROILERs subjected to COLD STRESS. Based on a 2×2 factorial arrangement, 384 day-old male BROILER chicks (Cobb) were randomly distributed between four experimental diets (with 8 replicates and 12 birds per replicate) included basal diet (as control) and the basal diet supplemented with 1200 mg/kg guanidinoacetic acid; 600 mg/kg BETAINE and 1200 mg/kg guanidinoacetic acid + 600 mg/kg BETAINE. In order to create COLD STRESS, on 21th day all birds were subjected to a low temperature (12-15° C), which was remained constant until the end of the experiment. According to results, increase in breast meat was observed in birds fed guanidinoacetic acid-included diet. Significant increase in lightness (L*) and redness (a*) of MEAT COLOR were detected in birds fed diets supplemented with guanidinoacetic acid and BETAINE. Decrease in crud fat percentage of breast meat was detected in birds fed the BETAINE-included diet. The meat pH decreased by time. Increase in meat pH was observed in birds fed the BETAINE-included diet. In conclusion, improving yield and decreasing crud fat percentage of breast meat were observed in birds fed the guanidinoacetic acid-and BETAINE-included diets, respectively. Color indices of BROILER breast meat was improved by diet supplementation with guanidinoacetic acid and BETAINE.
