Chinese herbal medicine feed additive capable of reducing ruminant methane output and improving feed utilization efficiency, and preparation method thereof

Abstract

The invention discloses a Chinese herbal medicine feed additive capable of reducing ruminant methane output and improving feed utilization efficiency, and a preparation method thereof; the Chinese herbal medicine feed additive is formed by crushing and mixing the following traditional Chinese medicine raw materials by mass: 110-150 parts of crowtoe, 80-130 parts of lespedeza, 90-130 parts of chinese soapberry, 30-90 parts of balloonflower root, and 50-100 parts of gynostemma pentaphylla; the Chinese herbal medicine feed additive takes 4%-10% in proportion in fine fodder supplement material of the ruminant; the ruminant fine fodder supplement material containing the Chinese herbal medicine feed additive takes 30-60% in proportion in full mixing daily food of the ruminant like cows and sheep. The Chinese herbal medicine feed additive is green, safe, environmental protection, substantial in effect, can solve the problems of carcinogenesis, mutagenesis effect, medicament residual and drug resistance caused by abuse of various antibiotic and chemical additives, thereby providing technology support of continuous development of the ruminant.

Description

technical field [0001] The invention relates to a natural plant feed additive for animals in the field of animal husbandry and veterinary medicine and a preparation method thereof, in particular to a Chinese herbal medicine feed additive which reduces rumen methane production of ruminants and improves feed utilization efficiency and a preparation method thereof, and also relates to a feed additive containing The Chinese herbal medicine feed additive is a concentrate supplement for ruminants. Background technique [0002] Methane (CH 4 ) of the greenhouse effect is carbon dioxide (CO 2 20 to 30 times that of 287Mt of methane emitted by global human activities into the atmosphere every year, among which methane produced by rumen fermentation in the process of energy metabolism of ruminants is about 77Mt, accounting for 27% of the total methane emissions 1% ~ 1.3% speed increase. Ruminant microbial fermentation produces methane, which is actually a waste of nutrients an...

Problems solved by technology

However, these halides are highly volatile and should not be used as feed additives. Among them, chloral hydrate, which is more widely used, has a toxic effect on the liver. Long-term use will cause animal poisoning and even death.

At the same time, methanogenic bacteria will also produce adaptability or degrade these compounds, making the effect of halogenated compounds in reducing rumen methane production unsatisfactory in actual production

②Monensin, lasalocid and other ionic antibiotics not only inhibit methanogenic bacteria, but also inhibit the bacteria that form hydrogen and formic acid in the rumen, which is beneficial to the bacteria that form succinic acid and propionic acid, resulting in an increase in the content of propionic acid. Change the type of rumen fermentation, reduce the generation of rumen methane, and improve the efficiency of feed conversion. The disadvantage is still that long-term use, rumen microorganisms will reduce the effect due to adaptability

Yet, do not see technology and patent report about this aspect so far
