Technical Field

The invention relates to the technical field of livestock breeding, in particular to a licking brick for preventing high-precision rumen flatulence of cattle and sheep.

Background

In order to improve meat production performance and meat quality of cattle and sheep in a fattening period, promote convenient transportation, storage, uniform stirring and the like of feeds, people continuously improve the use proportion of concentrated feeds such as grains and the like in daily ration of cattle and sheep. For example, in order to produce snowflake beef, the proportion of concentrated feed in daily ration of beef cattle at the later stage of fattening is improved to more than 90%. However, if the cattle and sheep are fed with high-precision feed daily ration for a long time, rumen flatulence of cattle and sheep can be caused, and the high-precision feed type rumen flatulence is called by people. People mainly add monensin plasma carrier antibiotics into daily ration to control the occurrence of high-precision rumen flatulence. However, after 2020, the feed in China will comprehensively enter the era of banning the use of antibiotics, and due to the serious shortage of high-quality coarse feed, China is used to feed high-precision feed daily ration for ruminant livestock for a long time, so the incidence rate of rumen flatulence of cattle and sheep in China will be greatly increased in future. Although the mortality rate is not high, rumen flatulence takes at least 15 days from onset, treatment to recovery, during which the production performance of animals is extremely significantly reduced and farmers suffer serious economic losses. Except for using antibiotics such as monensin, the existing technology can only treat and cannot effectively prevent the occurrence of high-precision tumor and flatulence. Therefore, after antibiotics are prohibited from being used on the whole feed, a technology capable of effectively preventing the high-precision feed tumor flatulence of the cattle and sheep is very needed in production.

The rumen of cattle and sheep generates a large amount of gases such as carbon dioxide, methane and the like every day, and the gases generated by the rumen can be discharged out of the body through eructation under normal conditions. The reason why the high concentrate ration induces the rumen flatulence of cattle and sheep is that a large amount of foam with stable properties is formed in rumen, the foam is a trap of gas, and the formation of a large amount of stable foam can cause the rumen gas to be incapable of flowing and discharging normally so as to generate the flatulence. Normal foam breaks down quickly after production, and rumen foam remains stable and does not break down, an important reason being that high-concentrate diets promote excessive proliferation of bacteria such as streptococcus ruminis, which secrete large amounts of soluble viscous polysaccharides. The concentrated feed of corn, wheat, etc. also contains a great amount of soluble non-starch polysaccharide. The polysaccharide is dissolved in rumen fluid, and the viscosity of the rumen fluid is increased, so that the stability of foam generated by the rumen fluid is greatly increased.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a licking brick for preventing high-precision feed type rumen flatulence of cattle and sheep.

The technical scheme adopted by the invention is as follows:

the licking brick for preventing high-precision feed type rumen flatulence of cattle and sheep comprises the following raw materials, by mass, 32-48 parts of salt, 16-24 parts of molasses, 0.08-0.12 part of a special green grass flavor type flavoring agent for cattle and sheep, 0.16-0.24 part of xylanase with the activity of 20000u/g, 0.16-0.24 part of β -glucanase with the activity of 50000u/g, 0.16-0.24 part of mannase with the activity of 50000u/g, 4-6 parts of an edible organic silicon ether defoaming agent, 4-6 parts of sodium bicarbonate, 4-6 parts of bentonite and 19.5-29 parts of cement.

Preferably, 40 parts of table salt, 20 parts of molasses, 0.1 part of a special green grass flavor type flavoring agent for cattle and sheep, 0.2 part of xylanase with the activity of 20000u/g, 0.2 part of β -glucanase with the activity of 50000u/g, 0.2 part of mannase with the activity of 50000u/g, 5 parts of an edible organic silicon ether defoaming agent, 5 parts of sodium bicarbonate, 5 parts of bentonite and 24.3 parts of cement.

Preferably, the edible grade organosilicone defoaming agent comprises the following raw materials in parts by weight: 1 part of polyoxypropyl polyoxyethylene glycerol ether, 2 parts of dimethyl silicone oil, 1 part of polyoxypropylene glycerol ether, 0.2 part of sorbitan monooleate, 0.2 part of polyoxyethylene sorbitan monooleate, 0.1 part of silicon dioxide, 0.25 part of sodium carboxymethylcellulose and 0.25 part of lecithin.

The invention has the beneficial effects that:

1. the non-starch polysaccharide enzyme such as xylanase, β -glucanase, mannan and the like is added into the licking block to reduce the viscosity of rumen fluid, the non-starch polysaccharide enzyme is taken in when animals lick the licking block, in the rumen, the non-starch polysaccharide enzyme can efficiently decompose soluble polysaccharide in feed and viscous polysaccharide synthesized by rumen microorganisms, the degradation of the polysaccharide can reduce the viscosity of the rumen fluid, so that the stability of rumen foam is broken and the rumen foam is easy to break, after the rumen foam breaks, the gas wrapped by the foam can be released out of the body through eructation, and the rumen flatulence disappears.

2. The licking brick is added with phagostimulant such as salt, molasses and flavoring agent to promote the secretion of saliva and inhibit the generation of foam in the process of licking by cattle and sheep. The phagostimulant such as the salt, the molasses and the like can lure the cattle and the sheep to lick the lick brick, and in the lick process, the phagostimulant can not only ingest additives such as non-starch polysaccharidase and the like and nutrients in the lick brick, but also can promote the cattle and the sheep to secrete a large amount of saliva. Research shows that the cattle and sheep saliva contains a protein component named bSP30, and the protein has the function of inhibiting rumen foam generation. Therefore, the lick block can promote the salivary secretion and has positive effect on preventing rumen flatulence.

3. And (3) adding a defoaming agent into the licking brick to promote rumen foam to be broken. The food grade organic silicon ether defoaming agent taking 20% of polyoxypropylene polyoxyethylene glycerol ether, 40% of dimethyl silicon oil and 20% of polyoxypropylene glycerol ether as cores is added into the lick brick, and the defoaming agent can permeate into a foam elastic membrane and is distributed in the membrane, so that the rumen foam membrane layer is broken by reducing the surface tension of the liquid membrane.
