| description | In recent years, the worrying generation of GHG from ruminant production has generated widespread interest in exploring nutritional strategies focused on reducing these gases, presenting the use of bioactive compounds (tannins) as an alternative in the diet. The aim of this research was to determine the effect of the addition of different levels of <i>Acacia mearnsii</i> on ruminal degradation, nutrient digestibility, and mitigation of greenhouse gas production. A completely randomized design with four treatments and six repetitions was used. The treatments were: T1, T2, T3, and T4 diets with, respectively, 0%, 20%, 40%, and 60% <i>A. mearnsii</i>. The rumen degradation kinetic and in vitro digestibility, and the production of gas, CH<sub>4</sub>, and CO<sub>2</sub> were evaluated. In situ rumen degradation and in vitro digestibility of DM and OM showed differences between treatments, with T1 being higher (<i>p</i> < 0.05) in the degradation of the soluble fraction (A), potential degradation (A + B), and effective degradation for the different passage rates in percent hour (0.02, 0.05, and 0.08), compared to the other treatments. Rumen pH did not show differences (<i>p</i> > 0.05) between treatments. The lowest (<i>p</i> < 0.05) gas, CH<sub>4</sub>, and CO<sub>2</sub> production was observed in treatments T1 and T2 with an approximate mean of 354.5 mL gas/0.500 g fermented DM, 36.5 mL CH<sub>4</sub>/0.500 g fermented DM, and 151.5 mL CO<sub>2</sub>/0.500 g fermented DM, respectively, compared to treatments T3 and T4. Under the conditions of this study, it was concluded that it is possible to replace traditional forages with up to 20% of <i>A. mearnsii</i>, without observing changes in the production of greenhouse gases with respect to the control treatment (0% of <i>A. mearnsii</i>); however, <i>A. mearnsii</i> is not usable because it significantly decreases rumen degradability of DM and OM, which would considerably affect the production in animals. |
