How to deal with cow dung in cattle farm?

In recent years, the cattle industry has developed rapidly, with the development of large-scale cattle farms growing, and the pollution problem of raising cattle is becoming more and more serious, the most prominent is the treatment of cow dung. A lot of cow dung is placed on the open space without treatment, resulting in air pollution, breeding a large number of mosquitoes and flies, affecting the surrounding living environment. Let's take a look at how to deal with cow dung in cattle farms.

Construction of biogas digester

The construction of biogas digester is the best way to deal with cow dung in small cattle farms. Using cow dung and cow farm pollutants as raw materials and investing thousands of yuan, it not only solves the source of fuel for the masses, but also makes cow manure fully mature. The residue and liquid of biogas are very good organic fertilizers, which can improve the internal quality of melons, fruits and vegetables and reduce investment. But now the construction of small biogas digester does not have the function of power generation, so it is generally suitable for the use of small cattle farms.

Cow manure organic fertilizer

Dried cow dung contains 10% of crude protein, 1% of crude fat, 20% of nitrogen-free extract and 15% of crude fiber, which has high nutrients and can become a high-quality organic fertilizer product after fermentation, which can fluffy the soil and improve the consolidation of the land. chelate the trace elements in the soil, improve soil fertility and so on. At the same time, using cow dung as raw material to produce organic fertilizer has the advantages of low cost, stable quality and large market sales space.

Raising earthworms with cow manure

At present, earthworm breeding is a new type of enterprise, with low cost and good profits. It can be raised by using cow dung. Cattle farms have more conditions for developing earthworm farming than others. Local materials are used, cow dung does not need to be bought, and feeding is simple. Increase the extra income of the cattle farm. Earthworm meal is a good feed additive, which has a higher protein content than fish meal. Moreover, all kinds of special fertilizers produced with earthworm manure as the main raw material can not only have high fertilizer efficiency, but also inhibit the spread of crop diseases and insect pests, but also improve soil temperature, conserve water and fertilizer.

Grow mushrooms with cow dung

Cow dung is the best raw material for growing mushrooms. In recent years, with the development of edible mushroom industry, the demand for cow dung is also increasing. The cow dung produced by a cow a year can grow one mu of mushrooms, and the output value of planting mushrooms per mu can exceed 10,000 yuan. The more popular is to use cow dung to grow Pleurotus ostreatus, the market price of Pleurotus ostreatus is stable, the main reason is that the planting area is small, and the main raw material of planting Pleurotus ostreatus is cow dung.

Production seedling soil

Seedling soil refers to the special soil prepared with field soil, rotten organic fertilizer, loose matter and chemical fertilizer according to a certain proportion, which requires complete nutrients, moderate alkali, loose permeability and strong water retention capacity. As one of the best fertilizers, cow manure can be used to produce cultivation substrate and bio-organic fertilizer with crop straw, which can not only reduce environmental pollution, but also meet the needs of the market.
