Abstract
La presente investigación se realizó en la granja Agropecuaria “La Campiña”, ubicada en el distrito de Chicama, provincia de Ascope, departamento de La Libertad, con el objetivo de evaluar el efecto de la inoculación in ovo de probióticos en gel de Aloe vera sobre los parámetros de incubabilidad de patos Muscovy. Se utilizaron 1950 huevos incubables de pata reproductora Muscovy, distribuidos bajo un diseño completamente al azar en tres tratamientos. Los tratamientos fueron, T0: Testigo (Embriones sin inoculación de cepas probióticas), T1: Embriones inoculados in ovo con 0.2ml de probióticos en gel de sábila, T2: Embriones inoculados in ovo con 0.4ml de probióticos en gel de sábila. El sustrato en estudio se inóculo a los 32 días de incubación. Para el análisis estadístico de los datos se utilizó el análisis de varianza y la prueba de Duncan. En el porcentaje de mortalidad embrionaria a la quinta semana, no se determinaron diferencias estadísticas significativas (P>0,05) entre los tratamientos, sin embargo T2 fue numéricamente inferior a T0 (0,1% vs. 0,3%). Para los porcentajes de mortalidad embrionaria total, se determinaron diferencias estadísticas altamente significativas (P>0,01) entre los tratamientos, T0 (11.9%) fue superior a T2 que obtuvo el menor porcentaje (5.8%). En patos de primera, se determinaron diferencias estadísticas altamente significativas (P>0,01) entre los tratamientos, T2 fue superior a T0 (36.1% vs. 26.7%). Para patos de segunda se determinaron diferencias estadísticas altamente significativas (P>0,01) entre los tratamientos, T2 fue inferior a T0 (0.4% vs. 2%). En porcentaje de incubabilidad se determinaron estadísticas altamente significativas (P>0,01) entre los tratamientos, T2 fue superior a T0 (23.9% vs. 18.8%). Y peso nacimiento se determinaron diferencias estadísticas altamente significativas (P>001) entre los tratamientos, sin embargo T2 fue superior a T0 (50,40 gr vs. 46,84 gr). Se concluye que el T2 mejora significativamente y numéricamente todos los parámetros de incubabilidad de patos Muscovy.
ABSTRACT This research was conducted at the Agricultural Farm "The Countryside" located in the district of Chicama, Ascope province, department of La Libertad, with the objective of evaluating the effect of ovo inoculation of probiotics in Aloe vera gel on hatchability parameters of Muscovy ducks. 1950 hatching eggs of breeding Muscovy duck, distributed under a completely randomized design in three treatments were used. The treatments were T0: Witness (Embryos without inoculation of probiotic strains), T1: Embryos inoculated in ovo with 0.2 ml of probiotics aloe gel, T2: Embryos inoculated in ovo with 0.4 ml of probiotics aloe gel. The substrate in study was inoculated at 32 days of incubation. For statistical analysis of the data, analysis of variance and Duncan test is used. In the percentage of the fifth week embryonic mortality, statistically significant differences (P> 0.05) between treatments they were not determined, but was numerically inferior to T2 T0 (0.1% vs. 0.3%). For percentages of the total embryonic mortality, highly significant statistical difference (P> 0.01) between treatments T0 (11.9%) they were determined was higher than T2 which had the lowest percentage (5.8%). At first ducks, highly significant statistical difference (P> 0.01) between treatments were determined, T2 was higher than T0 (36.1% vs. 26.7%). For ducks second highly significant statistical difference (P> 0.01) between treatments were determined, T2 T0 was lower (0.4% vs. 2%). As a percentage of hatchability highly statistically significant (P> 0.01) between treatments were determined, T2 was higher than T0 (23.9% vs. 18.8%). And birth weight highly significant statistical difference (P> 001) between treatments were determined, however T0 T2 was higher (50.40 vs. 46.84 gr gr). We conclude that the T2 improves significantly and numerically all parameters of hatchability in Muscovy duck.
