Comparative Plucking Force Characterisation of Chicken Produced From Two Breeds of Chicken
نویسنده
چکیده
The conversion of a live chicken into safe and wholesome meat products suitable for human consumption takes place in a series of processing steps. Few of the processes require force to carry it out successively among which are slaughtering and de-feathering. The latter is the focus in this paper, plucking force of chicken produced from two breeds of chicken. Each sample of the chicken carcass was loaded into the hanger and lowered into the rotary drum for plucking one at a time. The process took an interval of one minute from one temperature to another in order to determine the appropriate plucking force. The results obtained for plucking contour and down feather of local chicken carcass were 11.26N and 2.44N respectively at 85 o C for 5 minutes. The corresponding values for the exotic breed carcass in the order listed above are 4.13N and 1.02N respectively at temperature of 70 o C for 3 minutes. The results obtained showed that the two samples of chicken examined would meet-up with daily demand in relation to production rate domestically.

A comparative study was conducted to find out the differences in contribution of carcass cuts in meat production from indigenous breeds such as Vanraja, Aseel and Kadaknath breeds with respect to a broiler strain, Cobb-400. The primal cuts of Cobb-400 had significantly (P<0.05) higher weight than all indigenous breeds. Among indigenous breeds Aseel exhibited higher weight of all primal cuts exc...
