Embodiment 1
[0017] Embodiment 1 (the diet feed of cattle)
[0018] Table 1: Nutrient levels of basal diet (air-dried basal)
[0019]
[0020] On the basis of this basal ration, Gentiana was added according to the calf's body weight, and the proportions were 0% (control group), 0.01%, 0.02%, and 0.03% of the calf's body weight.

[0023] Note: BW 0.75 Indicates the metabolic weight of cattle, which is the power of 0.75 of body weight (BW), BW -0.75 because it is on the denominator;
[0024] a、b Indicates the significant difference between the two groups, that is, the control group 2.45 a The methane emission per unit metabolic body weight was significantly higher than that of the supplemented group 2.38 b .
[0025] It can be seen from Table 1 that the methane emission per unit metabolic weight of calves in the Gentiana supplementation grou...

The invention discloses a feed and a method for reducing methane emission of a ruminant, and relates to the technical field of livestock production. The method of the invention includes adding Gentiana macrophylla to ruminant daily ration, so as to reduce methane emission of the ruminant after feeding. The adding weight of Gentiana macrophylla is 0.005-0.03% of the weight of a test calf; preferably, the adding weight of Gentiana macrophylla is 0.01-0.03%; more preferably, the adding weight of Gentiana macrophylla is 0.02-0.03%. The method of the invention adopts Gentiana macrophylla as a dailyration supplement of the ruminant, and finds that Gentiana macrophylla can reduce the greenhouse gas emission of the ruminant by adding an appropriate amount of Gentiana macrophylla to the daily ration of the calf; and the method determines the optimum adding proportion of Gentiana macrophylla in the daily ration of the ruminant through multiple experimental studies, and develops the daily rationfeed which can significantly reduce the methane emission of the ruminant.
Description
technical field [0001] The invention relates to the technical field of livestock production, in particular to a feed and a method for reducing methane emission of ruminants. Background technique [0002] Methane is one of the most important greenhouse gases, and its greenhouse effect is 20-30 times that of carbon dioxide. According to the Food and Agriculture Organization of the United Nations, about 37% of the world's methane emissions come from livestock production, of which ruminants account for 33% of the total methane emissions and contribute 15% to global warming- 20%. The methane energy loss of cattle accounts for about 6% of the total energy consumed, and methane energy loss is an important reason for the reduction of pasture utilization. [0003] In order to solve the above problems, technicians have developed methane inhibitors, including rumenin, nitrate, Chinese herbal medicine additives, etc.; however, there are major technical difficulties in the process of c...
