Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reducing methane emissions, and in particular to a method for reducing methane emissions of ruminants. BACKGROUND

[0002] Greenhouse gases cause global warming and climate change, which is the focus of global attention. Methane produced by ruminants represents energy loss of ruminants and contributes to greenhouse gas emissions with global warming potential. In ruminants, about 95.5% of CH4 is produced by rumen feed fermentation, which is exhaled through the nose and mouth. According to different diets, the metabolic rate decreases by 2-12%. Therefore, finding a method to alleviate intestinal CH4 emissions has important effects on the ecological environment and economic benefits of feeding.

[0003] At present, some related technical solutions have been proposed in the prior art for how to reduce methane emissions of domestic ruminants, for example: (CN201910911431.6) "a feed and method for reducing methane emissions of ruminants", hereinafter referred to as comparative document 1, which specifically discloses "selecting gentiana as a ruminant daily ration additive, by adding an appropriate amount of gentiana in the daily ration of a calf, it is found that gentiana can reduce the emission of greenhouse gases by ruminants; and through repeated experimental research, the best addition ratio of gentiana in the daily ration of ruminants is determined, and a daily ration feed that can reduce the methane emission of ruminants is also developed, feeding the feed can significantly reduce the methane emission of ruminants";

[0004] However, the above technical solution directly adds an appropriate amount of gentiana in the feed of a calf to slow down the methane emission of ruminants. However, in the actual test and use process, it is found that the calf directly consuming gentiana and daily ration has many problems in the later physical growth and development. Since the calf consumes the daily ration in the later period, there is a probability of disease and death. If so, it will cause great loss to the current livestock field.

[0005] Therefore, the above technical solution has many defects, lacks practicability, and is not conducive to wide promotion in the market.

[0006] Therefore, how to reduce methane emissions of ruminants while ensuring normal growth and development of ruminants has become one of the main problems to be solved in the field. SUMMARY

[0007] Therefore, the present application aims to provide a method for reducing methane emissions of ruminants, so as to solve the problem in the prior art that methane emissions cannot be reduced while ensuring normal growth and development of ruminants.

[0027] Please refer to Figure 1The application provides a technical scheme: a method for reducing methane emission of ruminants, alfalfa and oat are fed in the morning;

[0028] Mahuai powder is fed at noon, and bran and soybean meal are added as concentrate lures, and premix is simultaneously fed to ensure normal growth and development of the ruminants;

[0029] Alfalfa and oat are fed at 7:30 in the morning and 18:00 in the evening;

[0030] Alfalfa and oat are fed at 7:30 in the morning and 18:00 in the evening, concentrate lures are fed at 14:30 in the afternoon, and mahuai powder is added, during which, the ruminants are allowed to drink water freely, and then premix is fed, so that the ruminants can reduce methane emission, and the bone development and normal growth of the ruminants are not affected, the survival rate and health rate of the ruminants are improved, and the mortality and morbidity of the ruminants are reduced;

[0031] The mahuai powder comprises gentianine, gentianine, gentiopicroside, swertiamarin and flavonoids.

[0032] In the embodiment, the alfalfa is 36.99 parts, the oat is 36.99 parts, the bran is 15.46 parts, the soybean meal is 10.31 parts, and the premix is 0.25 part, and the parts of the alfalfa, the oat, the bran, the soybean meal and the premix are further limited, so that the percentage of different components in the daily feed of the ruminants is determined, the feed with the ratio is used as the best embodiment, the methane emission rate can be reduced as much as possible, and the normal growth of the ruminants can be ensured by the relative proportion of the premix.

[0033] If the energy and growth demand of a cow with a body weight of 175 kg and a daily weight gain of 1 kg, then 1.91 kg of alfalfa and oat hay, 0.81 kg of bran, 0.53 kg of soybean meal and 12.9 g of premix are fed to each cow per day.

[0034] In the embodiment, the premix comprises vitamin A, vitamin D3, vitamin E, vitamin K3, vitamin B1, vitamin B2, vitamin B6, vitamin B12, nicotinic acid, calcium pantothenate, methionine and lysine, and the components of the premix are further limited, so that the growth state of the ruminants is better and the bone development is better after the ruminants consume the premix.

[0035] In the embodiment, 100 mg of mahuai powder is added per 100 kg of weight of the ruminants according to the body weight of the ruminants, and the application aims to improve the applicability of the technical scheme, the content of the mahuai powder added in the technical scheme is not fixed, but is adjusted according to the real-time body weight of the ruminants, so that the ruminants with different weights can also effectively reduce methane emission.
