Efecto de dos métodos de inmunocastración en los parámetros productivos de cerdas de engorde en la granja de la Corporación Fernández.

Abstract

The objetive of this research was to evaluate the effect of two methods of immunocastration on the productive parameters of sows of fattening in the farm Fernandez Corporation. This research was carried out in “Rancho Cielo” Porcine Farm, belonging to Santa Elena Province with a duration of 100 days, 612 bristles of the 100-day-old Pic line with an average weight of 55 kg were used. For the study, a completely random design (DCA) was applied, with six replicates and the experimental unit size was 34 animals housed in each pen that is 204 animals were worked for each of the treatments. Two methods of immunocastration were evaluated; T1, GnRF analog synthetic protein and T2, synthetic peptides of the hormone LHRH at the fattening stage to be compared with a control treatment (without immunocastration). The experimental results were subjected to a variance analysis (ADEVA) and a separation of means according to Tukey with a significance level of (P>0.05). The productive parameters of the sows determined highly significant differences (P>0.05). The highest profitability was obtained with the T2 treatment reaching a greater final weight with 129.56 kilos average, a weight gain of 72.46 kilos and a benefit/cost of 1.43$, being more efficient while the witnesses presented a final weight of 120 kilos and a daily weight gain of 54.64 kilos and a benefit/cost ratio of $1.38. It is concluded that T2 positively influenced the productive parameters of the fattening sows. Therefore, it is recommended to use T2, for greater final weight, greater total weight gain, and better utility.
