Embodiment 1

[0056] Embodiment 1 Composition of piggery fermentation bed

[0057] In addition to the necessary fences, food troughs, drinking water devices, humidification devices, and operating channels, the pens that use the fermentation bed to raise pigs also have new litter tanks, litter, litter inlets and outlets, litter seepage and ventilation. Mouth etc.

[0058] 1. The structure of the fermentation bed:

[0059] 1) Bedding trough: Build (or transform) 65-75% of the area in the pen into a submerged trough 50-80 cm lower than the hard ground platform, that is, the bedding trough, which is used to store pig bedding;

[0060] 2) Litter: Sawdust, straw powder, rice bran, pig manure and other organic matter are fermented, and after reaching the harmless index, the litter tank is filled and used as a pig gasket material. The litter height is 40-50cm for nursery pigs and 60-80cm for rearing pigs;

[0061] 3) The entrance and exit of litter is located on the outside of the pig house, whi...

Embodiment 2

[0076] Embodiment 2 Composition of fermentation bed

[0077] The structure of the fermentation bed and the production method of the bedding in this example are the same as in Example 1, but the following different organic materials are used to make the bedding: (please give different raw materials for preparing fermentation) Scheme 1:

[0078] Sawdust 800kg

[0079] Pig manure 200kg

[0080] 1 liter starter culture

[0081] Brown sugar 1 kg

[0082] Scenario 2:

[0083] Sawdust 500kg

[0084] Straw powder 300 kg

[0085] Pig manure 200kg

[0086] 1 liter starter culture

[0087] Molasses 1 kg

[0088] Option 3:

[0089] Sawdust 700kg

[0090] Straw powder 300 kg

[0091] 1 liter starter culture

[0092] Brown sugar or molasses 1 kg

Embodiment 3

[0093] Example 3 Fermentation bed pig raising in a certain pig farm in Beijing

[0094] Taking a pig farm in Beijing as an example, the farm has a scale of 5,000 commercial pigs per year, and uses the fermentation bed of Example 1 to raise pigs. The management plan includes:

[0095] 1) Stocking density

[0096] Nursery pigs: 0.3~0.7m 2 / head, breeding pigs: 0.7~1.5m 2 / head;

[0097] 2) Bedding disinfection

[0098] When the pigs are transferred to the pen, or after the bred pigs are released, the litter is disinfected. The method of litter disinfection is to sprinkle fresh sawdust or straw powder or rice bran on the surface of the litter, spray a proper amount of fermentation bacteria, mix evenly and adjust the water content to about 45%, and then pile them up. After the temperature of the pile rises above 50°C It can be kept for 24 hours, wherein the fermentation agent is the same as the above-mentioned fermentation agent;

[0099] 3) Midsummer Management

Abstract

The present invention relates to a fermentation bed for pigsty, comprising a groove for storing bedding materials, wherein the bedding materials formed by fermenting organic materials are laid in the groove. Using the fermenting bed to raise pigs can digest and decompose excrement such as feces and urine quickly, such that no flushing and no smell for the pigsty are in result by proper management and maintenance. The influence to the environment and residents around farms are greatly eased and the economic benefit is raised obviously.

Description

technical field [0001] The invention relates to livestock and poultry breeding technology, in particular to a pig house fermentation bed, and also relates to its application in raising pigs. technical background [0002] In recent years, the rapid development of large-scale livestock and poultry breeding has caused serious pollution to the environment. According to data in 2006, the total annual production of livestock and poultry manure in China is 2.4 billion tons, which has exceeded the production of industrial solid waste in that year, and the loss rate of breeding manure into water bodies is as high as 25-30%. largest source of water pollution. The country has included the prevention and control of livestock and poultry breeding pollution as a major project into the "Eleventh Five-Year Rural Well-off Environmental Protection Action Plan", and invested huge sums of money to support the resource utilization of livestock and poultry manure to improve the rural environment...
