“…In Canindé, Repartida, and Saanen goats, conventional feed enriched with condensed tannins from Acacia mearnsii (50 g/kg DM) has been shown to increase the levels of C14:1, cis -9, C18:2n6, C18:3n6, C18:3n3, polyunsaturated fatty acids (PUFA), and long-chain fatty acids. Simultaneously, it reduces the levels of C12, C14, and ω6/ω3, as well as the atherogenicity index, in milk fat, all without any modifications to nutrient intake or animal performance [ 112 ].…”

Small ruminants, such as sheep (Ovisaries) and goats (Capra hircus), contribute to approximately 475 million metric tons of carbon dioxide equivalent (MtCO2e) greenhouse gas (GHG) emissions, accounting for approximately 6.5% of the global emissions in the agriculture sector. Crop residues, silage, grasses, hay, browse, plant leaves, shrubs, agro-industrial by-products, poultry litter, and other alternative feed sources are frequently utilized for small ruminant production. The use of these valuable alternative feeds can significantly improve animal productivity and reduce carbon footprints and GHG fluxes, making it both environmentally friendly and cost-effective. Additionally, these alternative feeds possess antioxidant, antimicrobial, and antiseptic properties that can enhance the quality of the meat and milk produced. By impacting the bacteria involved in ruminal biohydrogenation, alternative feeds can reduce methane emissions and contribute to a decrease in the carbon footprint. Overall, the use of alternative feed sources for small ruminants generally improves their apparent nutrient digestibility and productivity, and has an impact on the production of greenhouse gases, especially methane. Finally, this review recommends evaluating the economic analysis of reducing methane emissions in small ruminants by utilizing different feed sources and feeding techniques.

The objective of this study was to determine the greatest concentration of condensed tannin (CT) extracted from Schinopsis brasiliensis in pornunça silages based on intake, digestibility, milk production, ingestive behavior and estimated greenhouse gas (GHG) emissions in dairy goats. Eight multiparous Saanen goats at 30 days of lactation, with 38.0 kg of initial body weight, production of 2.0 ± 0.4 kg of milk/day, mean age of 2–3 years, were distributed in a double Latin square (4x4) with four experimental periods and four diets with different tannin levels at concentrations 0% (control), 2.4, 3.6 and 4.8% tannin of total diet. The CT levels in the silage of pornunça promoted a linear decrease for the intake of dry matter (DM, P < 0.001), organic matter (OM, P < 0.001), ash (P < 0.001), crude protein (CP, P < 0.001), neutral detergent fiber (NDF, P < 0.001), acid detergent fiber (ADF, P < 0.001) and water (P < 0.001). The inclusion of CT also promoted a linear decrease in apparent digestibility coefficients of DM (P < 0.001), OM (P < 0.001) and CP (P < 0.001), milk production (P < 0.001), NDF (P < 0.001), and GHG emission estimation (P < 0.001). The intake and rumination rates of DM and NDF showed a linear decrease (P < 0.001) with level of tannin in the diets. In the experimental conditions, the inclusion of condensed tannin extracted from Schinopsis brasiliensis in pornunça silages, at levels up to 2.4% DM basis, promotes a decrease in intake of DM (DMI) and OM (OMI) and milk production as decreases GHG emissions in Saanen goats.
