Evaluación del uso de conjugado proteico de GnRH modificado con toxoide de difteria en la mejora de parámetros productivos y económicos en cerdas de la Granja “La Esperanza” faenadas a los 145 días de edad.

Abstract

In pig production, various alternatives are constantly sought and analyzed to improve performance and obtain the best possible benefits. In this sense, the present study sought to evaluate the use of modified GnRH protein conjugate with diphtheria toxoid in the improvement of productive and economic parameters in sows from "La Esperanza" Farm slaughtered at 145 days of age. The research was of a quantitative experimental approach with a descriptive and correlational study. Statistical analysis was performed using Excel software and the SPPS statistical package. The study was carried out at the "La Esperanza" Pig Farm from October 17, 2022 to December 31, 2022. The experiment consisted of supplying the modified GnRH protein conjugate with the diphtheria toxoid in an experimental group of 50 sows and a control group of 50 PIC Breed sows. Data on weight (GP), carcass yield (RC), backfat (GD), feed conversion (CA) and cost-benefits were collected. The results showed that the experimental group obtained better results; GP 118.77, GD 10.40, RC 81.33 compared to the control group with GP 115.85, GD 11.08 and RC 80.53 in the productive parameters, except for feed conversion which was 2.23 in the experimental group compared to 2.57 of the control group. It is shown that there is not a very low statistical correlation of carcass performance at slaughter with feed conversion and measurement of backfat, but with daily weight gain. Finally, it will be concluded that the experimental group presented greater economic benefits than the control group.
