Embodiment 1

[0012] Example 1. Triglycerol trinitrate and fumaric acid disodium salt combined preparation regulates rumen fermentation in vitro and reduces methanogenesis test.

[0013] 1 Material method

[0014] 1.1 Experimental materials

[0015] 1.1.1 Experimental animals and collection of rumen fluid

[0016] The experimental animals were 6 Hu sheep with permanent rumen fistula. Feed alfalfa hay and drink water ad libitum. Feed twice a day at 08:00 and 16:00. On the day of the test, rumen juice was taken half an hour before morning feeding, and fresh rumen juice was obtained from 6 fistula sheep and quickly filled into a thermos bottle filled with carbon dioxide and brought back to the laboratory.

[0017] 1.1.2 Preparation of artificial rumen fermentation broth

[0018] The preparation of fermented broth refers to the method of Menke and Steingass (1988). Filter the collected fresh rumen fluid with 4 layers of gauze, measure 1250ml of rumen fluid and quickly pour it into the pre...

Abstract

The invention discloses application of a glycerol trinitrate and disodium fumarate composition in preparation of a ruminant rumen methane inhibition and fermentation regulating agent. The invention also discloses application of the combination of glycerol trinitrate and disodium fumarate as an animal feed additive. Compared with the prior art, the rumen methane yield can be effectively reduced, the rumen fermentation function can be regulated and controlled, and the metabolic end products of the glycerol trinitrate in the rumen are propionic acid and ammonia which are non-toxic and can be utilized by animals. The production process of the glycerol trinitrate is mature, production facilities are simple, and rapid large-scale production can be realized to meet the requirement of carbon emission reduction in the cattle and sheep breeding industry in China.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to the application of glycerol trinitrate and disodium fumarate to prepare rumen methane inhibitors for ruminants. Background technique [0002] Rumen methanogenesis not only leads to 5-7% ruminant feed energy loss, but also an important source of greenhouse gases. Sheep produce an average of 10-16kg of methane per year, and cattle produce an average of 60-160kg. Therefore, the research and application of methane inhibitors for ruminants can not only improve the energy utilization efficiency and production performance of animals, but also have good ecological benefits. Although various feed additives (such as natural plant extracts, ionophores, polyhalogen compounds, electron acceptors, oils and nitro compounds, etc.) have been researched and developed, they all have different problems, such as long-term , safety and microbial tolerance issues. These drawbacks limit the w...
