520 3 _aThis study was conducted and made possible to determine which of the best withdrawal time prior to dressing is quite recommendable. Also to compare the average dressing percentage of broilers in relation to feed withdrawal time. It was started January 12 and ended January 15 covering a period of four days. It was conducted in the Poultry Project of the Don Severino Agricultural College, Indang, Cavite. A total of forty Indian River finished broilers were used in this experiment. They were divided into four lots, containing ten birds each lot. Lot I served as the control which were fed and dressed immediately. Lot II twelve hours withdrawal of feeds prior to bleeding, Lot III, twenty-four hours withdrawal of feeds and Lot IV, forty-eight hours withdrawal of feed, which were weighed and discharged just the same. A continuous supply of water was provided over the period. The initial weights obtained from four lots are as follows: 14,885.2 grams for Lot I; 14,600.1 grams for Lot II; 14,979.7 grams for Lot III; and 14,928.8 grams for lot IV. It has been observed that birds subjected to different withdrawal gave a decreasing result in final weight prior to killing. These were as follows: Lot 114,885.2 grams; Lotr-14,482.6 grams; Lot III 14,105.5 grams and lot IV 12,748.3 grams. Lot II and Lot III marked a slight decrease in weight than those of the birds in Lot IV, wherein a remarkable increase of shrink for live weight lead to the decreasing percentage of eviscerated weight as shown in Table 1. Table II, shows the average weight of the dressed birds. These were as follows: Lot I 1,005.9 grams; Lot II 1,009.96 grams; Lot III 902.92 grams and Lot IV 805.9 grams. However, Table III shows that the total average carcasses and entrails of the birds were 1,467.o8 for Lot I; 1,415.46 grams for Lot 11; 1,383.79 grams for Lot III and 1,195.13 grams for Lot IV. Table IV, shows that the dressing percentage of broilers did not very much, These were as follows; 67.602 for Lot I; 69.77% for Lot II; 64.16% for Lot ,IV.
