The present invention provides a combination of antioxidants that effectively stabilize different types of fats utilized in a ruminant diet. When included in a ruminant feed ration or water source, the antioxidant combination typically increases nutrient digestion, such as fiber and protein, improves rumen fermentation, improves microbial growth, improves microbial efficiency, increases milk production and / or milk fat, improves antioxidant status of the ruminant, and attenuates the negative effects of some fats in the ruminant animal.

The present invention relates to a feed supplement which comprises a resin acid based composition comprising over 10% (w / w) resin acids for use in the prevention of growth of harmful bacteria in the animal digestive tract, in the prevention of intestinal disorders, in the modulation of microbial population of the animal digestive tract, in enhancing rumen fermentation, lowering rumen methane production and / or in binding toxins. The invention further relates to a use of the feed supplement and a feed composition comprising the feed supplement.

The invention relates to a preparation method of a composite plant powder for minimizing methane output of rumen culture. Garden balsam, Atractylodes lancea and Yedo violet which are dried to constant weight are crushed according to a certain proportion to prepare the composite plant powder. By the addition of 0.2%, 0.5% and 1.0% of the powder, the output of methane of rumen culture within 24 hours are respectively reduced by 83.62%, 96.89% and 98.67% in comparison with a control group. In comparison with the methane output in a monensin treatment group, the methane output by the addition of 0.5% and 1.0% of the powder is respectively reduced by 23.69% and 32.31%. In the meantime, the powder can also increase the output of total volatile aliphatic acid and reduce propionic / acetic acid ratio, and has a better effect than monensin. It shows through results that the composite plant powder has a substantial effect of reducing methane as well as performance for improving rumen fermentation, and can replace antibiotics to regulate and control rumen fermentation and control methane generation. Therefore, health and environmental problems derived from antibiotics can be effectively eliminated.

The artificial rumen fermenting agent consists of rumen microbe 50-80 wt%, basidiomycetes colony 10-30 wt% lactic acid bacteria 5-30 wt% and saccharomycete 5-10 wt%. It has the advantages of decomposing cellulose, hemicellulose, lignin, etc. in stalk feed easily to raise the nutritive value, raise volatile fatty acid content, protein content and coarse fat content; raised feed utilization rate; and improved feed palatability.
