Problems solved by technology

However, the pig breeding in most areas of our country is still in the backward breeding concept, the breeding infrastructure is simple, the breeding management is not standardized, the environmental pollution is serious, the economic benefits are not ideal, and the environmental pollution brings the risk of a large number of pathogenic bacteria multiplying from many aspects. Opportunities, resulting in frequent occurrence of the disease, difficult to control

Embodiment 1

[0019] The bedding material is divided into two layers with a total thickness of 100cm. The bottom layer is 30cm of straw, and the upper layer is 70cm of sawdust, rice husk, coarse salt and fermented bacteria.

[0020] Fermentation bacteria are mixed with sawdust, rice husk and coarse salt, among which the bacteria agent is first expanded at a ratio of 1:10, that is, before the biological fermentation bacteria agent is applied, the bacteria agent is mixed with straw, sawdust, rice husk and coarse salt in proportion Add clear water and mix evenly, keep the water content of the mixture at 40-50% after mixing, and then ferment for 24 hours.

[0021] The straw and rice husk in the litter come from the farmland around the pig farm, the sawdust is waste from wood processing, and the biological fermentation agent is purchased from Shenyang Lvyuan Biotechnology Research Institute, wherein the fermentation agent is mainly composed of cellulosic bacteria, yeast Bacteria, lactic acid bac...

Embodiment 2

[0025] Litter composition: the total thickness of the pig bed is 90cm, the bottom layer is 40cm of straw, and the upper layer is 60cm of sawdust, rice husk, coarse salt, and a mixture of biological fermentation agents.

[0026] Wherein every cubic meter of sawdust adds 1 kilogram of biological fermentation bacterium, and the ratio (weight and number) of sawdust and rice husk is 7: 3, coarse salt and sawdust (weight percentage) 1: 0.2% simultaneously, sawdust and straw The mass fraction ratio is 7:3, the above-mentioned sawdust, rice husk, coarse salt and fermented bacteria are mixed in proportion and then fermented. After 2 days in summer, the pigs can be driven into the pen.

[0027] Adopt pig raising method of the present invention and pig raising on traditional cement ground as contrast, under the situation of raising conditions identical (epidemic number of times is identical, external temperature is at subzero 15-20 degree) show that adopt the method for ecological pig rai...

Embodiment 3

[0029] Litter composition: The total thickness of the pig bed is 95cm, the bottom layer is 30cm of straw, and the upper layer is 70cm of sawdust, rice husk, coarse salt, and a mixture of biological fermentation agents.

[0030] Wherein every cubic meter of sawdust adds 1.5 kilograms of biological fermentation bacteria agents, and the ratio (parts by weight) of sawdust and rice husk is 7: 3, while coarse salt and sawdust (weight percentage) 1: 0.3%, sawdust and straw The mass fraction ratio is 7:3. After mixing the above-mentioned sawdust, rice husk, coarse salt and fermentation agent in proportion, after 5-7 days of fermentation in winter, the pigs can be driven into the pen. Among them, broken straw can be used instead of part of the sawdust or rice husk.

[0031] Adopt the method for raising pigs of the present invention and raise pigs on the traditional cement ground as contrast, under the same situation of raising conditions (the number of times of epidemic prevention is t...

Abstract

The invention relates to animal husbandry culture, in particular to a method for ecologically raising pigs by using a biological fermentation bed. Live pigs are raised on a bed ring; a backing material for the bed ring is divided into two layers, the bottom layer is provided with straws, and the upper layer is provided with sawdust, rice husks, coarse salt and biological fermentation inoculants, wherein 0.8 to 1.5 kilograms of biological fermentation inoculants are added into each cubic meter of sawdust, and the mass percent ratio of the sawdust to the rice husks is 7 to 3; meanwhile, the mass percent of the coarse salt to the sawdust is 1: 0.1- 0.3 percent; and the mass percent ratio of the sawdust to the straws is 7 to 3. The method has the advantages of saving energy, protecting environment, saving materials with high efficiency, improving the body performance of stunting pigs, recovering the growth situation and improving the birth giving rate of sows by 30 to 50 percent, and is suitable for large, medium and small-sized culture.

Description

technical field [0001] The invention relates to animal husbandry, in particular to a method for ecologically raising pigs using a biological fermentation bed. Background technique [0002] In the traditional breeding mode, feed additives are widely used, and feed additives often contain a certain amount of heavy metals. About 100,000 tons of heavy metals are used in feed additives in my country every year, and these heavy metals are discharged with livestock manure and pollute the environment. According to the survey, heavy metal elements such as arsenic, cadmium, chromium and copper in pig manure seriously exceed the national urban waste agricultural control standard (GB 8172-87). There are also many reports abroad that the content of heavy metal elements in livestock and poultry manure is too high. It is estimated that a pig farm with 10,000 heads is calculated based on the dosage of arsenic preparations allowed by the US FDA. If the arsenic-containing medicated feed is ...
