It was already reported the loss in weight of animal during transportation and the loss of Carcass weight in the previous report. This is the results of study on the loss in weight of broiler during transportation, and the loss in weight of broiler coming from freezing and losses of other meats from freezing and defreezing process. Broilers lost their weight by 1.69-2.01% during transportation which is low comparing with those of cattle and swine. In the line of production processes of frozen broiler, loss in weight by freezing went so high as to 6.31% in case of non-prepacking. When it was prepacked with polyethylene, the loss was 0.71%, and with stockinet, it was 4.3%. When the closed type meats (chicken, pork, beef) under rigor mortis were frozen directly at 13℃ below zero and defrozen in the open air, chicken showed a decrease by 17.7%, pork 13.5%, beef by 20% respectively. After the processes of cooling and chilling, opened type meats were frozen for 2 days and wrapped with polyethylene bag and defrozen for 4 hours in cool water, then, the loss was 7% in chicken, 6.2% in pork. and 10.6% in beef.
