RESUMEN
The effect of castration i.e. deficiency of testosterone, on protein metabolism was studied in rabbits for two months. The results revealed a significant decrease in total protein, albumin, alpha1, and alpha2 globulin throughout the experimental periods. Meanwhile, beta and gamma globulins displayed a temporarily increase and a delayed decrease respectively. On the other hand, the catabolic product compounds, uric acid and urea but not creatinine increased significantly. Moreover, liver function test transaminases [S. GPT and S. GOT], alkaline phosphatase and gamma-glutamyl transferase [gamma-GT] displayed no significant alterations throughout the experimental periods. These results indicated that the possible increase in the weight of the animal is not due to excessive meat production but a possible increase in fat deposition as a consequence of new docile behaviour of the castrated animal
