Ecological pig breeding system and method

Abstract

The invention belongs to the technical field of livestock breeding, and provides an ecological pig culture system. The ecological pig culture system comprises a fermentation stirring tank, a pig house, a biogas tank and a green feed field, wherein the fermentation stirring tank communicates with a pig trough in the pig house through a first pipeline; a spray washing disinfection pipe and a decontamination trench are further arranged in the pig house; the spray washing disinfection pipe is connected with a supernate layer of the biogas tank; the decontamination trench is connected with a feed port of the biogas tank; a biogas residue layer of the biogas tank is provided with a biogas residue conveying device leading to the green feed field; and a circulating pump, an electromagnetic valve and a pressurization device are all connected with a controller. The invention also provides an ecological pig culture method. The ecological pig culture method comprises the following steps: feed fermentation, feed conveying, manure conveying, circulating washing and disinfection of the pig house through the supernate in the biogas tank, and green feed planting. The invention solves the problems that too many bacteria and viruses exist in the pig house, a large amount of manure-containing water difficult to treat is produced due to irrational flushing, and no green healthy ecological pig can be bred because breeding personnel only pay attention to the pig breeding efficiency and universally pursue the growing speed by means of antibiotics.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and particularly relates to a clean and pollution-free ecological pig breeding system and method. Background technique [0002] my country is the largest livestock and poultry breeding country in the world. As far as pig farming is concerned, in recent years, my country's pig production has made great progress. Ecological pig raising is based on the premise of respecting the basic rights of pigs to survive, restoring their eating habits, taking the production of healthy food as their own responsibility, and engaging in an efficient pig raising production model without destroying the natural environment. [0003] For the research on ecological pig raising, most of the attention is paid to pesticide residues in feed, no heavy metals, no additives other than inorganic salts, pig excrement to be treated innocuously, and biogas fermentation to be used as fertilizer for crops to grow green fodd...

Problems solved by technology

[0009] The invention proposes an ecological pig breeding system and method, which solves the problem that pig houses contain more bacteria and viruses in the prior art, and unreasonable flushing produces a large amount of dung that is difficult to handle, and the breeders only pay attention to the efficiency of raising pigs, so they are widely used Antibiotics pursue growth speed, cannot raise green and healthy ecological pigs, and solve the technical problem of low automation of pig raising
