Method for breeding ecological pigs

Abstract

The invention discloses a method for breeding ecological pigs. The method includes: building a orchard around a pig farm, building a methane gas pool under the pig farm, and cleaning a ground surface of a pig house activity zone; discharging liquid dung into the methane gas pool; leading methane gas liquid into the orchard around the pig farm to water fruit trees; planting Citrus maxima trees or apple trees in the orchard; planting a medicinal material-Fritillaria cirrhosa among the Citrus maxima trees or the apple trees; mixing leaves of sweet potatoes and / or leaves of the Citrus maxima trees or the apple trees and a pig fodder to feed pigs; and numbering unit houses, and putting the pigs into the orchard to stock in turns according to the numbers. Through the ecological breeding mode of pig-methane gas-fruit tree-vegetable-pig, zero release of sewage can be achieved, the conditions of the housings can be improved, stink is reduced, mosquito breeding is reduced, occurrence of an epidemic disease of the pigs can be reduced, and the quality of pork can be improved.

Description

technical field [0001] The invention belongs to the technical field of breeding vertebrates, and in particular relates to a method for breeding ecological pigs. Background technique [0002] In the past ten years, due to important reasons such as environmental pollution, severe epidemics, unsound standards of veterinary drugs, feed and food, backward testing methods and equipment, lax supervision, and economic interests in the process of production and distribution, the safety of livestock products has become a threat. People's health and the survival of animal husbandry are serious problems that affect export earnings. In addition to epidemic diseases, various drugs, chemical substances, heavy metals, biological hormone residues and pollution are also increasingly harmful to the hygienic quality of animal products, especially through mad cow disease and bird flu. , Clenbuterol incident, the government will focus on the monitoring of food safety in formulating industry norms...

AI Technical Summary

Problems solved by technology

[0003] 1. The variety is poor, and the penetration rate of improved breeds is not high. Almost 70% of the farmers are still raising soil pigs. The scale is small and there is basically no environmental protection equipment, which leads to the discharge of pig excrement and urine waste water. First, it affects water quality. Contains a large amount of organic matter and organisms. When decomposed, it will consume dissolved oxygen in the water, thereby destroying the ecological balance. For example, when the water source of tap water is polluted by pig excrement and urine wastewater, the water will have a bad smell, which will affect people's application. For example, in fish ponds When the water source is polluted by pig feces wastewater, the water will become smelly, and the dissolved oxygen in the water will be scarce, making fish and shrimp unable to survive;

[0004] 2. The breeding environment is poor, the housing conditions are poor, and the smell is strong, which leads to the breeding of a large number of mosquitoes, and mosquitoes are the number one killer of swine epidemics;

[0005] 3. There is a greater threat of disease;

[0006] 4. The production efficiency is low. The slaughter rate in developed countries has reached over 190%, and the feed-to-meat ratio is 2.5-2.8:1. However, the current slaughter rate in Chongqing is only about 90%, and the feed-to-meat ratio is around 3.2-3.5:1;

[0007] 5. The degree of industrialization is not high
