Abstract
El presente trabajo se realizó en la granja experimental de la Pontificia Universidad Católica Sede Ibarra, parroquia de Imbaya, cantón Antonio Ante, provincia de Imbabura. El objetivo de esta investigación fue determinar la digestibilidad in vivo (DIV) e in vitro (IVDT) en ovinos de raza Pelibuey utilizando dos tipos de dietas a base de forraje conservado. Se evaluó el heno de alfalfa (T1), heno de mezcla forrajera (T2) y pasto verde kikuyo como testigo (T0), el diseño que se utilizó fue un diseño completamente al azar (DCA) con 3 tratamientos y 4 repeticiones, dando como resultado 12 unidades experimentales (UE). Los análisis de la digestibilidad in vivo en el (T1) reflejaron diferencias significativas para proteína bruta (PB) 19% y fibra cruda (FC) 42% de nutrientes digestibles totales (NDT) de materia seca (MS), mientras que el T2, presento de PB 9% y 58% de FC y el T0 presento de PB 48% y 5% de FC. Por otra parte, la respuesta para la digestibilidad in vitro (IVDT) nos muestra un 72% para el T1, un 75% para T2 y un 99% para T0 de IVTD. Claramente indica que la especie Ovis aries, presenta una respuesta positiva en la absorción de nutrientes para los forrajes conservados estudiados. Se concluye que brindar forrajes conservados favorece a los productores al generar mayores utilidades a corto plazo, al ser un alimento más digestible y apetecible el ovino aprovecha de mejor manera y se da un mayor consumo y por ende una mayor ganancia de peso, conversión alimenticia y condición corporal.
This investigation was done in the experimental farm of the Pontificia Universidad Católica campus Ibarra, Imbaya parish, Antonio Ante canton, Imbabura province. The objective of the investigation was to determine the digestibility in vivo (IVD) and in vitro (IVDT) in Pelibuey breed sheep using two types of diets based on preserved forage it was evaluated. Alfalfa hay (T1), forage mix hay (T2) and kikuyo green grass were evaluated as a wintness (T0), the desing that was used was a completely randomized desing (DCA) arrangement with 3 treatments and 4 repetitions, resulting in 12 experimental units (UE). The in vivo digestibility analyzes in (T1) reflected significant differences for crude protein (CP) 19% and crude fiber (FC) 42% of total digestible nutrients (NDT) of dry matter (DM) while T2, I present of PB 9% and 58% of FC and T0 presented of PB 48% and 5% of FC. On the other hand, the response for in vitro digestibility (IVDT) shows us 72% for T1, 75% for T2 and 99% for T0 of IVTD. It clearly indicates that the species Ovis aries presents a positive response in the absorption of nutrients for the conserved forages studied. It is concluded that providing preserved forages favors producers by generating greater profits in the short term, as it is a more digestible and palatable food the sheep takes better advantage of it and there is a greater consumption and there fore a greater weight gain food conversion and body condition.
