Problems solved by technology

Therefore, in today's increasingly scarce protein feed resources, a large amount of nitrogen in feed cannot be effectively absorbed and utilized by dairy cows, which not only increases feed costs, but also causes extremely serious pollution to air, soil and water.

Embodiment 1

[0016] A dairy cow feed that effectively inhibits the growth of rumen protozoa, including a basal ration, and 0.5 grams of hops and 0.2 grams of cerium chloride heptahydrate are added per kilogram of basal rations, and the α-picric acid content in the hops is 3.6%. , β-picric acid is 3.7%.

[0017] The basal diet includes the following components by weight percentage: 15.0% of alfalfa, 2.0% of oats, 13.58% of pressed corn, 9.21% of soybean meal, 5.93% of cottonseed, 4.10% of expanded soybean, 5.38% of beet meal particles, and 1.65% of corn distiller's grains , 1.53% rapeseed meal, 1.39% bran, 1.0% molasses, 2.26% fat powder, 2.79% feed regulator, and the rest is whole plant corn silage.

[0018] Described feed conditioner is:

[0019] 35.84% of the premix, 21.15% of baking soda, 5.02% of magnesium oxide, 10.39% of zeolite powder, 20.07% of calcium hydrogen phosphate, 7.17% of salt, and the rest is molasses. The per kilogram of the premix contains the following components by w...

Abstract

The invention discloses a dairy cow feed capable of effectively inhibiting rumen protozoa growth. The feed comprises a basic ration, and 0.5 g of hop and 0.2 g of a rare earth compound are also addedinto each kilogram of the basic ration. The dairy cow feed can effectively inhibit growth and reproduction of the protozoa in the rumen, so that the conversion of nitrogen elements in the feed by dairy cows is improved, the feeding cost is reduced, and the environment is effectively protected.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a dairy cow feed that can effectively inhibit the growth of rumen protozoa. Background technique [0002] How to improve the absorption of nitrogen in feed by dairy cows has always been a huge challenge in the dairy farming industry. According to reports, the utilization rate of nitrogen in feed by dairy cows is only 20-35%, and the remaining unused nitrogen will be discharged into the environment with feces. Therefore, in today's increasingly scarce protein feed resources, a large amount of nitrogen in feed cannot be effectively absorbed and utilized by dairy cows, which not only increases feed costs, but also causes extremely serious pollution to air, soil and water. [0003] An important indicator to evaluate the utilization rate of rumen protein is the rumen nitrogen retention rate. A higher nitrogen retention rate can improve the utilization rate of feed protein and reduce the...
