Example Embodiment

[0018] Example 1

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

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

[0021] The straws and rice husks in the litter come from farmland around the pig farm, sawdust is wood processing and production waste, and the biological fermentation inoculum was purchased from Shenyang Lvyuan Biotechnology Research Institute. The fermentation inoculum is mainly composed of cellulosic bacteria and yeast It is composed of bacteria, lactic acid b...

[0024] Example 2

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

[0026] Among them, 1 kg of biological fermentation inoculants are added to each cubic meter of sawdust, and the ratio of sawdust to rice husk (weight parts) is 7:3, and the ratio of coarse salt to sawdust (weight percentage) is 1:0.2%. The mass fraction ratio is 7:3, the above-mentioned sawdust, rice husk, coarse salt and fermentation inoculants are mixed in proportion and fermented for 2 days in the summer, and the pigs can be driven into the pen.

[0027] Using the pig raising method of the present invention and traditional cement ground pig raising as a control, under the same feeding conditions (the same number of epidemic prevention, the outside temperature is minus 15-20 degrees) shows that the ecological pig raising method of the present inven...

[0028] Example 3

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

[0030] Among them, 1.5 kg of biological fermentation inoculants are added to each cubic meter of sawdust, and the ratio of sawdust to rice husk (parts by weight) is 7:3, and the ratio of coarse salt to sawdust (weight percentage) is 1:0.3%, and the ratio of sawdust to straw The mass fraction ratio is 7:3, the above-mentioned sawdust, rice husk, coarse salt and fermentation inoculants are mixed in proportions and fermented for 5-7 days in winter, and the pigs can be driven into the pen. Among them, broken straw can be used to replace part of sawdust or rice husk.

[0031] Using the pig raising method of the present invention and traditional cement ground pig raising as a control, under the same feeding conditions (the same number of epidemic preven...

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 ...
