Abstract: ONATE, WENIFREDO T. University of the Philippines at Los Banos, College, Laguna, March, 1983. Capon Production From Broiler Cockerels. Major Professor: Dr. Elpidio C. Coligado Two separate experiments were conducted simultaneously from February 1, 1 982 to June 13, 1932 to determine the optimum slaughter ago of capons and to compare three feeding schemes for capon production. Experiment I which was composed of three groups with capons and intact cockerels under each group was conducted to determine the effects off caponization on the performance of broiler cockerels raised from 4 to 12, 16 and 19 weeks of age. On the other hand, experiment which consisted of capons subjected to three feeding schemes from 4 to 19 weeks was conducted to determine the influence of dietary treatments on the performance of capons. Experiment I showed that caponization had a slight depressing effect on the growth of Dale broilers but statistical analysis revealed no significant differences in growth between the capons and cockerels at any age studied. Although no significant differences on feed consumption and feed conversion efficiency were observed with capons showed slightly better feed conversion efficiency than the intact cockerels. Dressing percentage and carcass scores were found to be better for the capons than the intact cockerels at 12, 16 and 19 weeks of age. Organoleptic scores were consistent-ly better for the capons than the cockerels although the difference upon statistical analysis was found to be insignificant. Experiment II showed no significant influence of any of the feeding schemes used on the growth, feed consumption and feed conversion efficiency of capons at 19 weeks Mortality, dressing percentage and quality of carcass wore also found to be not significantly affected by the feeding schemes. Based on the results of these two experiments capon raising was generally favorable than the intact cockerels especially on the quality of the meat. Obviously, meat production from capons is much more expensive than raising ordinary broilers, there-fore, capons must be sold at a higher price than the prevailing price of broilers. Capon can be ready for market as early as 12 weeks of ago but if larger capons are desired, they can be grown much longer. Large capons must correspondingly be priced much higher to obtain reasonable net profits.

Two separate experiments were conducted simultaneously from February 1, 1 982 to June 13, 1932 to determine the optimum slaughter ago of capons and to compare three feeding schemes for capon production. Experiment I which was composed of three groups with capons and intact cockerels under each group was conducted to determine the effects off caponization on the performance of broiler cockerels raised from 4 to 12, 16 and 19 weeks of age. On the other hand, experiment which consisted of capons subjected to three feeding schemes from 4 to 19 weeks was conducted to determine the influence of dietary treatments on the performance of capons.
Experiment I showed that caponization had a slight depressing effect on the growth of Dale broilers but statistical analysis revealed no significant differences in growth between the capons and cockerels at any age studied. Although no significant differences on feed consumption and feed conversion efficiency were observed with capons showed slightly better feed conversion efficiency than the intact cockerels.
Dressing percentage and carcass scores were found to be better for the capons than the intact cockerels at 12, 16 and 19 weeks of age. Organoleptic scores were consistent-ly better for the capons than the cockerels although the difference upon statistical analysis was found to be insignificant.
Experiment II showed no significant influence of any of the feeding schemes used on the growth, feed consumption and feed conversion efficiency of capons at 19 weeks
Mortality, dressing percentage and quality of carcass wore also found to be not significantly affected by the feeding schemes.
Based on the results of these two experiments capon raising was generally favorable than the intact cockerels especially on the quality of the meat. Obviously, meat production from capons is much more expensive than raising ordinary broilers, there-fore, capons must be sold at a higher price than the prevailing price of broilers.
Capon can be ready for market as early as 12 weeks of ago but if larger capons are desired, they can be grown much longer. Large capons must correspondingly be priced much higher to obtain reasonable net profits.
