Additive Tannins in Ruminant Nutrition: An Alternative to Achieve Sustainability in Animal Production

Sustainable intensification involves maintaining ecosystem balance and increasing productivity per animal unit area. Phytogenic additives can be used as an alternative to achieve sustainable intensification. Tannins are phenolic compounds present in plants that classified according their chemical structure into hydrolyzable condensed compounds. When added ruminant diets, tannins exert effects on rumen fermentation, such a reduction protein degradation enteric methane production of dry matter ingested, may also improve weight gain. The advantage this mechanism is it increases dietary utilization, reduces nitrogen excretion urine, nitrous oxide emissions. However, the positive these nutritional require further investigation. Therefore, objective review demonstrate results hitherto known use nutrition. result both negative effects, depending sources doses administered.
