Methane regulating agent containing candida tropicalis and application of methane regulating agent

Abstract

The invention relates to a methane regulating agent containing candida tropicalis and an application of the methane regulating agent. The methane regulating agent is prepared from candida tropicalis, calcium chloride, ammonium sulfate and lactose. The application refers to an application of the methane regulating agent in preparation of feed used for ruminant and capable of reducing methane emission. The methane regulating agent is developed, except that candida tropicalis having a main function is added, lactose, ammonium sulfate and calcium chloride are also added to the formula, lactose and ammonium sulfate serve as nutritious supplements to the candida tropicalis, and calcium chloride serves as an activating agent, so that the survival and reproductive capacity of the candida tropicalis is improved. Actual detection of carbon dioxide and methanol emission of mutton sheep in 24 h proves that the methane regulating agent can reduce the methanol emission of the ruminant to a certain extent, the fermenting property of rumen is improved, the fermenting type of the rumen is improved, the energy utilization rate of the feed is increased, the digestibility of nutritious substances can still be improved, and the methane regulating agent is superior to other methane inhibitors.

Description

Technical field [0001] The invention relates to the field of ruminant breeding, in particular to a premix feed capable of reducing methane emissions from cattle and sheep. Background technique [0002] Ruminant rumen is a dynamic ecosystem, its methane (CH 4 The production of) is a complex process and is an inevitable product of carbohydrate fermentation in the rumen. However, methane emissions will reduce feed utilization and increase the greenhouse effect. Therefore, it is necessary to adopt scientific and reasonable measures to regulate it. [0003] At present, there have been many studies on the regulation of rumen methane. As a new type of green additive, microecological preparations have little side effects on animals and the environment. The application in ruminant production is mostly focused on promoting growth, preventing diseases, and increasing production performance. There are many reports, but they are rarely seen. Methane regulation. [0004] Therefore, finding suit...

Problems solved by technology

When yeast culture was added to the barley-based diet, CH in the rumen was found within 12 to 24 hours after feeding. 4 Yield is reduced to some extent (Mutsvangwa, 1992 (The effect of dietary inclusion of yeast culture (Yea-Sacc) on patterns of rumen fermentation, food intake and growth of intensively fed bulls [J]. Anim Prod, 1992, 55 : 35-40. )); Qiao Guohua et al. (2006) used a short-term artificial rumen fermentation method and found that the culture of Candida tropicalis reduced the rumen CH of dairy cows. 4 Yield

However, because the in vitro method cannot simulate the real rumen environment of the animal body, the dose obtained by it is difficult to be directly used in the actual production

[0006] The inventor found in practice that the effect of directly feeding Candida tropicalis to reduce methane emissions is unstable. In order to increase its effect, the inventor conducted a large number of experiments and finally proposed the present invention
