Evaluación de la digestibilidad in vivo de dietas con follaje de acacia mearnsii en ovinos criollos.

The objective of the research was to evaluate the in vivo digestibility of the chemical composition of diets with Acacia mearnsii foliage fed to Creole sheep; the leaves of this shrubby plant were collected from the Patate canton; then subjected to a drying process in order to make a pelleted food for easy administration. Four Creole sheep of a year and a half were used, the same ones that were dewormed and vitaminized, they were placed in metabolic cages for a period of 68 days; of which there were 12 days of adaptation and 5 of sampling. Subsequently, the respective analyzes were carried out in the Ruminology laboratory of the Technical University of Ambato, in which the digestibility of NDF, FDA, MS and OM was determined; In addition to this, in vitro gas production was performed. The variables were analyzed by means of a one-way ANOVA, obtaining 59.7 % and 55.0 % of in vivo digestibility of dry matter, organic matter for T2 before the other treatments with the inclusion and without the inclusion of acacia; while, for the same T2, neutral detergent fiber and acid detergent fiber do not affect microbial degradation and reduce the production of incubated and fermented gases from the evaluated treatments. Concluding that T2 (80% P. clandestinum + 20% A. mearnssi); and the addition of 20% condensed tannins maintains digestibility, reducing the production of greenhouse gases, creating regenerative livestock.
