    Broccoli production in Ecuador has led to a significant amount of waste, much of which ends up being discarding and contributing to environmental pollution. As a result, new alternatives are being explored to repurpose broccoli as a potential feed source in the livestock industry. To this end, silages fermented for 21 and 45 days were analyzed using the in-situ degradability method in two rumen-fistulated sheep, with incubation period of up to 72 hours. Additionality, a two-phase in vitro intestinal digestion procedure was applied. The silages showed a higher organic matter content (93,1 to 98%), and crude protein levels (up to 17%) compared to the control sample (88,4 and 6,4%, respectively) regarding cell wall composition, the silages had a higher level of hemicellulose and lignin, while cellulose content was high in the silages (4620-4930 kcal/kg DM), and although digestible energy for lactation were higher in the silages. The silages enriched with the Poultrygrow 250® additive achieved over 90% degradability along with an 82% in vitro intestinal digestibility rate. Significant differences were observed in the degradable fraction, while the undegradable fraction and the degradation rate (P < 0,01) also yielded favorable results in the additive-treated silages. Total digestibility values were 78,5% for the silage and 78% for the broccoli.
