Problems solved by technology

The regulation of diet and feeding technology has a certain effect on methane emission reduction, and there are many studies; although the regulation of additives has a certain effect, it is likely to have a negative effect on animals; in addition, immune regulation is a new method to reduce methane emissions from ruminants. train of thought

Embodiment

[0014] Raw materials: red yeast rice, lovastatin content 0.2%, of which the open-loop ratio is 60%, the closed-loop ratio is 40%, rice. The experimental animals were 12 healthy castrated Poza goats, all of which were 20 months old, with an average body weight of 40±1.51kg. The formula of the basic diet for the test was prepared according to the Chinese mutton sheep feeding standard (2004) 40kg, twice the standard required for maintenance. The ratio of dietary concentrate to coarse is 3:7.

[0015] The formula and nutritional level of the basic diet are shown in the table below:

[0016]

[0017] Note: 1) The premix is ​​provided for the diet: Fe(as ferrous sulfate) 30ppm; Cu(as copper sulfate) 10ppm; Zn(as zinc sulfate) 50ppm; Mn(as manganese sulfate) 60ppm; VA2937IU; VD343IU; VE30IU.

Abstract

The invention discloses application of red yeast rice to reduction of methane discharged by ruminant such as sheep. When the red yeast rice is added into ruminant feed to reduce methane discharged by ruminant, the additive amount of the red yeast rice in the daily ration of sheep depends on the average daily feed intake of the sheep, the content ratio of nutrients to lovastatin in the red yeast rice and the ratio of opening loops to closed loops of lovastatin. The red yeast rice is adopted for reducing methane discharged by sheep, and the added red yeast rice naturally containing lovastatin can competitively and powerfully inhibit 3-hydroxy-3-methylglutaryl-coenzyme A reductase and cut off the passage for synthesizing methane bacteria membrane lipid, thereby effectively inhibiting the growth of methane bacteria and eventually reducing methane discharged by ruminant such as sheep.

Description

technical field [0001] The invention relates to the application of red yeast rice, in particular to the application of red yeast rice in reducing methane emission of ruminant sheep. Background technique [0002] Methane (CH 4 ) is a kind of greenhouse gas, and its greenhouse effect is carbon dioxide (CO 2 ) 25 times, accounting for 16% of global greenhouse gas emissions, the amount of CH4 emitted into the atmosphere around the world is about 535Tg (410-660Tg) every year, and the methane emitted by agricultural production accounts for about 50% of the total amount of methane emitted by human activities. The most important source is rumen fermentation of ruminants, whose methane emission reaches 85Tg (65-100Tg) per year, and contributes 2% to the global greenhouse effect. Methanogens in the rumen of ruminants use hydrogen (H2) produced by the bacteria to convert CO 2 reduced to CH 4 , CH 4 The production of is the main cause of energy loss in rumen fermentation. Therefor...
