Abstract

number of 60 birds from broiler chickens aged 42 days old were slaughtered after it reared at a private farm in Damascus rural. The chest and the thigh were separated from the carcass, then the specific parts of every carcass were soaked in a cold water (to 2 oc) for different periods 3, 6, 9, 12 hours, then the chest and thigh were grilled roasted. There was a significant difference between the different time treatments 3h:9h,3h:12h,6h:9h,6h:12h respectively concerning the absorbed water in the thigh, the total amount of infiltration water was evaluated as 10.15%, 13.2%, 15.16% and 17.85% respectively. The weight of the chest increased insignificantly, as previous time periods differes by about 7.58%, 10.43%, 11.22%, 11.52% respectively. The edible parts of internal organs increased by 6.57 %, 10.36 %, 11.8 %, 12.59 % for the mentioned periodical treatments, respectively, and the differences were statistically significant at those periodical treatment 3h:6h, 3h:9h, 3h:12h, but insignificant differences were found for weight of grill carcass which evaluated as 3.87 %, 4.53 %, 4.98 %, 5.32 %,respectively. The quantity of lost liquid increased as time periods increased, for thigh, where the lost fluids volumes recorded 43.43 %, 48.39 %, 50.53 % and 53.11 % for the mentioned periods respectively. The differences were significant for the treatments of 3h:12h, 6h:12h, 9h:12h ,while the differences were not significant between the different time treatments for the quantity of lost liquids from chest grilled, the evaluated was as 43.37 %, 55.15 % 57.82 %, 58.9 %, respectively. There were positively significant correlation coefficients between the weight of both thigh and chest before grilling and the quantity of lost liquids during grilling which varied between 0.45 and 0.99.
