Ecological pig raising method by fermentation bed

Abstract

The invention provides an ecological pig raising method by a fermentation bed. The ecological pig raising method includes the following steps: 1), producing fermentation bed packing; 2), producing the fermentation bed; 3), raising pigs on the fermented fermentation bed in a staged rotation mode. The ecological pig raising method has the advantages that the weaning nursery pigs are raised on a single fermentation bed in a staged rotation mode, space temperature is guaranteed through high-density single-rail raising in a nursery stage, bed bearing capacity is guaranteed through the staged rotation raising mode in a breeding stage, and the unit-area raising amount of the fermentation bed is guaranteed through a communicated-rail raising mode in a fattening stage; by the staged raising mode, utilization efficiency of the fermentation bed packing is remarkably improved, and bed maintenance cost and management workload are remarkably reduced.

Description

technical field [0001] The invention relates to a method for raising pigs ecologically in a fermentation bed, belonging to the technical field of animal husbandry. Background technique [0002] In recent years, the state has continuously strengthened energy conservation and emission reduction in rural areas, encouraged the development of circular agriculture, and increased efforts to prevent and control agricultural non-point source pollution. Relevant departments in various provinces and cities have also vigorously promoted energy conservation and emission reduction in rural areas, emphasizing the in-depth promotion of clean production in agriculture and animal husbandry, the development of ecological animal husbandry, and the strengthening of livestock and poultry breeding waste management. With the vigorous promotion of ecological farming, the zero-emission concept brought about by the fermentation bed farming method has also been deeply rooted in the hearts of the people...

Problems solved by technology

Under this principle, most pig farms across the country that adopt fermentation bed technology use wood chips as the main bedding material, accounting for 80%-90% of the total bedding material, supplemented by some crop straw, such as corn stalks, beans, etc. Straw, rice husk, peanut shell, cottonseed husk, coarse bran, etc., account for 10%-20% of the litter, but the quality of wood chips used in various regions varies. The main problem is that wood chips are used to make chipboard, veneer particleboard, etc. A by-product of engineering boards, although the urea-formaldehyde glue in the production of these boards is added with formaldehyde scavenger to capture the closed free formaldehyde, but this cannot completely prevent the overflow of free formaldehyde, so when using wood chips as fermented mattress materials, This toxic substance may be introduced into the fermentation bed, which will greatly affect the microbial activity in the bedding of the fermentation bed, resulting in the death of a large number of microorganisms in the bedding, resulting in the danger that the microorganisms cannot decompose pig excrement, resulting in a dead bed In addition, the harmful components in the process of wood chip production will also affect the pig body, which is not conducive to the healthy growth of pigs

In addition, the large-scale use of wood chips has also caused an imbalance in the ratio of wood chip purchases and sales in some areas, and the price of wood chips has skyrocketed. Criminals take advantage of this opportunity to cut down a large number of trees to make wood chips, which will also cause vegetation damage and affect the balance of the ecosystem.
