Embodiment 1

[0028] The present invention is a comprehensive method for reducing the emission of odor from traditional open or semi-open pig farms, which includes: reducing the emission of odor by using the method of front-end control + process control + terminal control;

[0029] (1) Front-end control method: add fermented feed, yucca extract and coated lactic acid bacteria to commercial pig feed; in commercial pig feed, the addition ratio of fermented feed is 5%-10%, 8% is better; yucca The addition ratio of the extract is 0.01%-0.03%, 0.02% is better; the addition ratio of coated lactic acid bacteria (coated Enterococcus faecium) is 0.03%-0.05%, and 0.04% is better; that is, every ton of commercial pig feed Among them, the addition ratio of fermented feed is 50-100kg, 80kg is better; the addition amount of yucca extract is 100g-300g, 200g is better; in each ton of feed, the addition amount of coated lactic acid bacteria (coated Enterococcus faecium) 300g-500g, preferably 400g.

Embodiment 2

[0045] A comprehensive method for reducing odor emissions in closed pig farms, including: using front-end control + process control + terminal control methods to reduce odor emissions;

[0046] (1) Front-end control method: add fermented feed, yucca extract and coated lactic acid bacteria to commercial pig feed; in commercial pig feed, the addition ratio of fermented feed is 5%-10%, 8% is better; yucca The addition ratio of the extract is 0.01%-0.03%, 0.02% is better; the addition ratio of coated lactic acid bacteria (coated Enterococcus faecium) is 0.03%-0.05%, and 0.04% is better; that is, every ton of commercial pig feed Among them, the addition ratio of fermented feed is 50-100kg, 80kg is better; the addition amount of yucca extract is 100g-300g, 200g is better; in each ton of feed, the addition amount of coated lactic acid bacteria (coated Enterococcus faecium) 300g-500g, preferably 400g.

[0047] The fermented feed is a product made of corn, soybean meal and bran mixed ...

Abstract

The invention discloses a comprehensive method for pig farm odor emission reduction. The method comprises front-end control, process control and terminal control. The front-end control mainly adds a fermented feed, yucca extract and coated lactic acid bacteria into a commercial pig feed; the process control mainly installs an automatic spraying device in a pig house, and sprays microorganism deodorization bacteria for deodorization; and the terminal control is mainly a technology for carrying out odor treatment on the tail end under the condition that odor still exists after the odor source isdeodorized. Aiming at a traditional open type or semi-open type pig farm, a spraying pipeline is installed on a fence of a pig farm boundary, connected to a spraying main machine and used for spraying a plant essential oil deodorant; and aiming at a closed pig farm, a circle of spraying pipeline is installed on the inner side of an air outlet of a fan and connected to a spraying main machine to spray a plant essential oil deodorant. By the adoption of the comprehensive method, the odor level outside and around the enclosing wall of the pig farm boundary can be well reduced, and complaints ofsurrounding residents are eliminated.

Description

technical field [0001] The invention belongs to the technical field of odor reduction in pig farms, and relates to a comprehensive method for reducing odor in pig farms. Background technique [0002] At present, even under the country's policy of vigorously encouraging breeding, odor is still a major problem plaguing pig farms. Residents will complain through various channels if the smell of pig farms is high, which will affect the survival of pig farms. Therefore, reducing (reducing until eliminating) pig farm discharge odor is a problem to be solved urgently by pig raising enterprises. [0003] At present, for traditional pig farms (open or semi-open, that is, with windows, or even without windows, exposed), the main comprehensive method for reducing odor emissions in pig farms is: adding probiotics to the feed Bacteria and other deodorizing additives, as well as the use of artificial spraying microbial deodorization technology in the pig house, this spraying microbial de...
