Problems solved by technology

[0005] Methane produced in the rumen is not only a greenhouse gas, but also wastes 2-5% of energy
Current research shows that plant extracts such as tannins such as catechins, saponins such as tea saponin, and plant essential oils such as lauric acid can be used as rumen fermentation regulators and methane inhibitors, but they are generally expensive and palatable in cattle production. Use restrictions such as bad sex

Abstract

The invention discloses a feed additive for reducing methane emission of a bovine rumen, and a preparation method of the feed additive for reducing methane emission of the bovine rumen. The preparation method comprises the following steps: active substances and a carrier are evenly mixed, then an aqueous solution of a polysaccharide hydrophilic gel skeleton material is added for mixing, granulation is conducted, and low-temperature drying is conducted to obtain inner layer enveloped granules; the bio-degraded skeleton material and a film-forming agent are dissolved into an ethanol solution toobtain a mixed solution; a rumen fermentation regulator and the carrier are mixed to obtain a mixed material; the surfaces of the inner layer enveloped granules are sprayed with the mixed solution, then the inner layer enveloped granules are sent into the mixed material for rolling, then placed into the mixed solution to be subjected to still standing, and filtered, solids are sieved, and drying is conducted to obtain the feed additive for reducing methane emission of the bovine rumen.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for reducing ruminal methane emission of cattle and a preparation method thereof. Background technique [0002] The methane produced in the gastrointestinal tract of cattle is difficult for cattle to digest and utilize, and is usually excreted in the form of belching. The rumen of cattle is a complex micro-ecosystem, and its methane production is affected by many factors. The main factors affecting the ruminal methane production of cattle are the type of feed, the composition of the diet and the efflux rate of chyme in the rumen. [0003] After the feed is eaten by cattle, it is first anaerobically fermented under the action of microorganisms in the rumen. After carbohydrates and cellulose that are difficult to degrade in monogastric animals are fermented, substances that can be continuously digested and utilized by the body are produced. During this proce...
