"Evaluación de uso de leche descremada en polvo UHT de cabra como conservante del semen porcino bajo refrigeración"

Abstract

In the present investigation, the efficiency of using skimmed UHT goat's milk powder as a refrigerated pig semen extender was evaluated, which was carried out at the “El Tillo” site of the Abdón Calderón parish. The ejaculate of a boar of the Landrace breed was divided into four fractions, whose treatments consisted of (T1 = 60% goat milk and 40% BTS + Gentamicin, T2 = 75% goat milk and 25% BTS + Gentamicin, T3 = 100% goat milk + Gentamicin) and a control group (100% BTS), obtaining 26 samples of 5 ml per treatment; with a duration of 6 days, evaluating the samples in an interval of 12 hours. The results were analyzed using the analysis of variance (ANOVA) test, with a completely randomized design. The changes in the microscopic parameters presented by the sperm cells of the pig under refrigeration were evaluated. Motility (mass and individual) and viability were significant (p <0.05) during the entire preservation process. T0, T1 presented better parameters with respect to T2, T3. The treatment based on skimmed UHT goat's milk powder obtained a conservation period of 24 hours, being economically profitable only if it is used in the aforementioned period of time, therefore it can be implemented as a short-term diluent, where it is not its use is ruled out in future research
