Valoración de la inmunocastración versus la castración quirúrgica sobre los parámetros productivos en cerdos

Abstract

The objective of this research was to evaluate the effect of immunocastration (Innosure) versus surgical castration on the productive parameters of male pigs in Grupo La Oriental Farm. This research was carried out at the ''CANTAPEZ'' Pig Farm, located in La Maná Canton, Cotopaxi Province, using 120 weaned male pigs, surgically castrated pigs (day 3 of age) with an average weight of 5.64 kg and immunocastrated pigs (Innosure; first dose at day 70 of age and second dose at day 130) with an average weight of 5.71 kg. The Student's t-test was used for the study with a significance level of (P<0.05) and (P<0.01). Two castration methods were evaluated; T1, Surgically castrated and T2, Immunocastration with 60 replicates for each treatment, 60 animals per pen were housed, that is, 60 pigs per treatment and per corral. The productive parameters measured in the study determined statistical differences (P< 0.05) for the whole pigs in the lactation stage, post-weaning and in the growth-fattening stage for the immunocastrated pigs, these obtained an average final weight of 102.67 kg with a profitability of $1.20 while for the surgically castrated pigs it was $1.11 with an average final weight of 91.33 kg. It is concluded that T2 had a positive influence on the productive and economic parameters of the male pigs, therefore, it is recommended to use T2 to obtain better meat quality, higher final weight, higher total weight gain since this brings less investment cost in feed since they are ready for sale in less time, according to the management of the farm.
