Suplementación de ovejas mestizas con subproducto molido de maíz durante el engorde en el cantón Joya de los Sachas.

Abstract

In Joya de los Sachas, many of the small producers are still unaware of the potential of using corn byproducts that can be used as growth and fattening promoters for crossbred sheep. Therefore, the objective of the present study was to evaluate the effect of the ground piquillo corn byproduct on the breeding of crossbred sheep. The evaluation was carried out for 56 days at the ''La Fortaleza'' sheep farm, using a completely randomized design with three treatments: T1 (grazing + 2000 g of piquillo + 333 g of mineral salt), T2 (grazing + 1600 g of piquillo + 333 g of mineral salt) and T3 (grazing + 1000 g of piquillo + 333 g of mineral salt), the study included nine repetitions with a total of 27 female crossbred sheep (Pelibuey, BlackBelly, Katahdin and Santa Inés) between 1 and 3 years of age. The data were collected weekly, recorded in Excel sheets and analyzed using the SAS v program. 9.4. Regarding the results, T1 (39.35 kg) was the one that obtained the greatest weight, the greatest weight gain, the greatest food consumption and the best benefit-cost performance, compared to the results of treatment T2 (37.27 kg) and T3 (35.37 kg). It is concluded that supplementing crossbred sheep with ground by-product of "piquillo" corn turns out to be a strategy to optimize their performance, improving not only their weight gain, but also contributing positively to productive responses in terms of sheep production.
