Embodiment 1

[0026] Example 1: The effect of adding different doses of grape seed proanthocyanidin additives on the production of rumen fermentation methane under the corn stalk + high-quality protein feed source diet

[0027] This test has designed three kinds of grape seed proanthocyanidin additives (table 1) of different proportioning,

[0028] The inhibitory effects of rumen fermentation methane production were analyzed and compared.

[0029] Table 1 Different doses of grape seed proanthocyanidins additive treatment

[0030]

[0031] Lactating Holstein cows were used as experimental animals, and corn stalks + high-quality protein feed source diets were used as feed fermentation substrates. The formula was: corn stalks 36.08%, soybean meal 11.28%, rapeseed meal 4.19%, cotton meal 3.14%, 3.06% puffed soybean, 4.16% beet pulp, 10.44% cotton seed, 25.54% corn, 0 wheat bran, 0.73% stone powder, 0.46% salt, 0.92% baking soda.

Embodiment 2

[0038] Example 2: Effects of adding different doses of grape seed anthocyanin additives on rumen fermentation methane production under corn stalk + miscellaneous meal protein feed source diet

[0039] Lactating Holstein dairy cows were used as experimental animals, and corn stalk + miscellaneous meal protein feed source diet was used as the feed fermentation substrate. The formula was: corn stalk 36.06%, soybean meal 0, rapeseed meal 9.63%, cotton meal 6.70%, Puffed soybeans 0, beet pulp 7.08%, cottonseed 10.44%, corn 23.5%, wheat bran 4.48%, stone powder 0.73%, salt 0.46%, baking soda 0.92%. In the concentrate, high-quality soybean meal feed raw materials are used to replace part of miscellaneous meal raw materials, which can represent the types of mixed rations with different nutritional levels that are often prepared by small and medium-scale dairy farms in northern my country. h 2 , CO 2 、CH 4 The yield assay method is the same as in Example 1.

Embodiment 3

[0044] Example 3: Effects of adding different doses of grape seed anthocyanin additives on rumen fermentation methane production under alfalfa hay + corn silage source diet

[0045] Lactating Holstein cows were used as experimental animals, and alfalfa hay + corn silage-derived diets were used as feed fermentation substrates. The formula was: corn straw 0, alfalfa hay 18.3%, corn silage 19.77%, soybean meal 11.26%, vegetable Meal 4.19%, cotton meal 2.13%, puffed soybean 2.06%, beet pulp 4.16%, whole cotton seed 10.44%, corn 25.54%, wheat bran 0, stone powder 0.73%, salt 0.46%, baking soda 0.92%. Its roughage source consists of whole plant corn silage and high-quality alfalfa hay, which can represent the total mixed ration often used in large-scale intensive cattle farms in my country. h 2 , CO 2 、CH 4 The yield assay method is the same as in Example 1.

Abstract

The present invention discloses a grape seed proanthocyanidin additive and a preparation method and an application thereof. The grape seed proanthocyanidin additive is prepared by evenly mixing grape seed proanthocyanidins, corn starch and rice hull powder at a weight ratio of (3-15) : 1 : 2. In the production practice of livestock breeding industry and especially in the processing of ruminant feed, the grape seed proanthocyanidin additive is added, which can significantly reduce the generation amounts of rumen fermentation carbon dioxide and hydrogen up to 34% and 78% and thus effectively reduce methane emissions up to 45%. The grape seed proanthocyanidin additive is simple in preparation method, strong in operability and suitable for the breeding practical application of ruminate animals of dairy cattle, beef cattle, mutton sheep, etc., can significantly inhibit the methane greenhouse gas emissions of the ruminant animals, and have very important significances for improving feed energy utilization efficiency, saving energy and reducing emission, and controlling the greenhouse effects.

Description

technical field [0001] The invention relates to a grape seed proanthocyanidin additive and its preparation method and application, in particular to a grape seed proanthocyanidin additive for inhibiting rumen fermentation methane generation and its preparation method and application. Background technique [0002] In recent years, with the increasingly prominent problem of global warming, including methane (CH 4 ), carbon dioxide (CO 2 ) and other greenhouse gas emissions are getting more and more attention. Rumen fermentation in animal husbandry production practice will produce a large number of methanogens and methane (CH 4 ), ruminant livestock such as beef cattle, dairy cows, goats, sheep, etc. are CH 4 major contributor to emissions. It has been reported that CH produced annually in the rumen of ruminants 4 It accounts for 37% of total global methane emissions from human activities. Rumen fermentation CH 4 Emissions not only have a non-negligible impact on the gree...
