Embodiment 1

[0038] The effects of additives on methane, rumen fermentation environment, and the number of cellulolytic bacteria were tested in vitro and in vivo.

[0039] According to the test, 200mg containing 70% hay, 18% corn, 6.5% soybean cake, 2.5% cottonseed cake, 2% premix, 1% salt are uniformly ground and mixed through a 40-mesh analytical sieve, and then added to the fermentation bottle . Add the additives in the preferred proportions of the present invention to the bottles containing the above-mentioned feed mixes in triplicate.

[0040] Three sheep were fed the ground feed and 500 ml of coarsely filtered rumen fluids were mixed with 1000 ml of colemans simplex. The buffer has the following composition:

[0041] colemans simplex slow liquid

[0042]a Trace element solution: Dissolve CaCl2.2H2O 13.2g, MnCl2.4H2O 10.0g, CoCl2.6H2O 1.0g, FeCl3.6H2O 8.0g with distilled water, cool, and dilute to 100ml.

[0043] b Buffer solution: NaHCO3 35.0g, NH4HCO3 4.0g, dissolve in distilled...

Embodiment 2

[0062] The additive extract of the preferred formulation of the present invention was blended with the additive amount of 1.5% in Example 1, and the effects of feeding sheep in the feed on methane production, rumen internal environment indicators and the number of fibrinolytic bacteria. Twelve 1.5-year-old Karakul sheep weighing about 30 were randomly divided into two groups. The experimental animals were housed in well-ventilated metabolic cages, single cages, and equipped with automatic drinking water devices. The animals were fed at 5:30 in the morning and 5:30 in the afternoon, and had free access to water throughout the day. The feed intake and remaining feed of the experimental sheep were recorded every day, and samples were taken to determine the dry matter intake. According to Johnson et al. (1994) SF6 tracer technology to measure the amount of methane production, while collecting rumen fluid to measure the rumen environment index and the number of fibrinolytic bacteri...

Abstract

The invention discloses an additive for reducing methane release of ruminant rumen. The additive is prepared from the following at least three raw materials: licorice root, halostachys caspica and alhagi sparsifolia or alhagi sparsifolia secrete thorn sugar. The raw materials are added into ruminant feed or drinking water in a certain ratio.

Description

technical field [0001] The present invention relates to an additive for animal feed or drinking water, in particular, the present application relates to an additive for reducing rumen methane release of ruminants. Background technique [0002] Methane from livestock (CH 4 ) The total amount is estimated to be 8 × 10 3 g / a, most of which come from ruminants. During the ruminant metabolism of ruminants, the methane produced by the rumen is the main cause of energy loss caused by rumen fermentation, and about 6%-15% of the feed energy is consumed in the form of methane. loss (Johnson et al., 1995). In addition, global warming is also an issue of international concern and key research. IPCC (2000) research shows that the global average annual temperature will rise by 1.8 to 2.5 ℃ by 2010, which has an extremely important impact on human health and the ecological environment. There are currently 6 major greenhouse gases, including CO 2 , CH 4 , N 2 O, etc., where CO 2 The ...
