Observações preliminares sôbre caponização de frangos "Leghorn" com estrogênios

Abstract

The effect of "Capastrol", pellets of diethilstilbestrol at 0,015 g., in 12 weeks S. C. W. Leghorn cockerels, was studied. The results secured are in accordance with those obtained by other authors and can be resumed as follows: 1) paleness and shrunken of the comb, whose size is reduced, in comparison with the controls; 2) no differences in the total weight gain between control and treated lot; 3) size of testis greatly reduced in treated males; 4) improvement of meat by fat deposition in chickens that received treatment.
