Evaluación de dos métodos de castración en los parámetros productivos en cerdos mestizos

Abstract

This research proposes to carry out the evaluation of two castration methods in the productive parameters of crossbred pigs, on the Rancho Bonanza farm, located in the Agua Chica sector, Santiago canton, Morona Santiago province; 16 male pigs were used, divided into two treatments T1 treatment, which consisted in surgical castration and T2 treatment, immune-castration with 8 repetitions giving a total of 16 experimental units, using a descriptive statistic measures of central tendency and dispersion. The productive behavior of the crossbred pigs determined that by using the immune-castration method a higher final weight (84.08 kg) is achieved, total weight gain (84.08 kg), and weight gain every 7 days (6.33 kg), and a lower feed conversion (2.44), that is to say, the application of the determined product for immune-castration (IC) purposes achieves the process of meat development in the pig, preventing the interest of the female and therefore a physiological wear. The quality of the immune-castrated pig carcass is superior since the thickness of the back fat is 10,625 mm, that is, a leaner meat is produced. The profitability of the castrated pig's production with the immune-castration system was superior compared with the surgical castration method (1.24), establishing a value of 1.28 is to say that for each dollar invested a profit of 28% is expected.
