Disclosed are ruminant feed additive compositions comprising phytochemicals and/or vegetable extracts containing tannins essential oils, optionally saponins and optionally other phytochemicals, buffered with a plurality of acid-neutralizing calcium, magnesium, potassium, and/or sodium salts having pKa's effective at different ruminal and gastrointestinal pH ranges, where the combination of ingredients and their quantities are selected to provide compositions that improves dietary energy and nitrogen utilization efficiency and are effective to reduce greenhouse gas (GHG) emission from the animals. Also disclosed are methods of reducing GHG emissions from ruminants by feeding an effective amount of the composition in an animal feed.
A feed additive composition for ruminants that reduces greenhouse gas (GHG) emission from the animals, the composition comprising the following combination of ingredients:
The composition of any one of the preceding claims, wherein the essential oils comprise one or more of Limonene, Garlic, Capsicum, and Lycopene.
The composition of any one of the preceding claims, wherein the saponins comprise one or more extracts of Yucca, Quillaja, Soapberry, Soapnut, Oleander, and Ginseng.
The composition of any one of the preceding claims, wherein the other phytochemicals comprise one or more extracts of Cashew nuts, Dandelion, Mustard and Safflower.
The composition of any one of the preceding claims, wherein the plurality of acid neutralizing buffer salts comprises at least one salt with a pKa effective to neutralize acids within the pH range of the rumen, and at least one salt with a pKa effective to neutralize acids within the pH range of the ruminant intestine.
The composition of any one of the preceding claims, further comprising magnesium oxide.
The composition of any one of the preceding claims, further comprising bentonite.
The composition of any one of the preceding claims, further comprising an active probiotic culture.
The composition of any one of the preceding claims, further comprising an active Saccharomyces cerevisiae yeast culture.
The composition of any one of the preceding claims, wherein the acid neutralizing buffer salts comprise between about 66% by weight and about 90% by weight of the composition.
