Abstract

The invention relates to a method for producing and fermenting pig feed by utilizing pigeon manure. The invention relates to a method for processing the feed, in particular to a method for producing and fermenting the pig feed by utilizing the pigeon manure. The method comprises the following steps of mixing 90 percent of fresh pigeon manure, 7 percent of wheat bran and 3 percent of rice bran, adding 0.5 percent of a manure fermenting agent, adding water, facilitating the water content of 45 to 50 percent, uniformly mixing, laying the mixture onto a bamboo curtain, enabling the thickness of a material layer to be 15cm to 20cm, aerobically fermenting the mixture for 15h to 18h at the temperature of 30DEG C to 32DEG C, then transferring the mixture into a closed plastic bag to be continuously anaerobically fermented for 10days to 15days at the temperature of 42DEG C to 45DEG C. The cured fermented material has the fragrance of the wine and no odor. The feed is used for feeding the pigs, not only can partial protein feed be substituted, the breeding cost be reduced and can the shortage problem of the feed be solved, but also the pigeon manure in a pigeon field can be cleared in time, the environmental sanitation of the pigeon field can be improved, the injurious insects such as mosquitoes and flies can be reduced, and the environmental pollution can be greatly alleviated.

Description

A kind of method of utilizing pigeon dung to produce fermented-pig feed

(1), technical field

What the present invention narrated is a kind of processing method of feed, specifically a kind of method of utilizing pigeon dung to produce fermented-pig feed.

(2), background technology

Raising year by year along with living standards of the people, the aquaculture of China has also obtained swift and violent development, but meanwhile, also there is the problems such as short-commons, aquaculture cost raising in China's aquaculture in recent years, in order to solve people and animals, strive the contradiction of grain, how to develop new feed resource and substitute grain, seem very important.

Pigeon dung is that in all conventional feces of livestock and poultry, nutritive value is the highest, because dove intestines are too short for cattle and sheep goose pig, the time that food stays in enteron aisle is not long, so the nutrient of pigeon feed generally can only absorb 1/3rd left and right wherein, major part excretes from rectum.Pigeon dung is containing crude protein approximately 28%, and total amino acid 8%, and each seed amino acid comparison balance, in addition, also contain abundant B family vitamin and various trace elements.So pigeon dung is cheap low energy protein feed, with pigeon dung, replace Partial Protein feed, the economic benefit of raising pigs can be greatly improved, and pollution can be reduced, environment purification, forms Ecological Industry Chain.But in pigeon dung, contain germ and the insects such as coliform, nematode, pig is directly edible may cause morbidity, health to edible pork also exerts an influence, undressed ight soil in addition, and smell is pungent, be difficult for transportation, volume is large, active ingredient is low, nutrient loss is also more serious.

If pigeon dung is fermented, can take oxygen mode by force by aerobic microbiological during the fermentation checks the breeding of the pathogen in ight soil, by producing metabolite and physiological activator, kills the pathogenic microorganism in ight soil, in the ight soil simultaneously fermenting, produce multiple digestive ferment, vitamin and a large amount of UGF, can improve ight soil nutrition, improve the immunity of organisms of pig.

(3), summary of the invention

Utilize the fermentation pigeon dung live pig of feeding, not only can Substitute For Partial protein feed, reduce aquaculture cost, solve the problem of feed shortage, can also remove in time the pigeon dung in dove field, improved the environmental sanitation of dove field, the contraction that has reduced the insects such as mosquitos and flies is raw, can greatly alleviate environmental pollution.This is also purpose of the present invention.

The object of the present invention is achieved like this:

Fresh pigeon dung 90%, wheat bran 7%, rice bran 3% mix, add 0.5% manure fermentation agent, adding water makes water content in 45～50% left and right, mix, tile to bamboo curtain splint, thickness of feed layer 15～20cm, first 30～32 ℃ of aerobic fermentations 15～18 hours, proceed to again 42 ℃～45 ℃ continuation anaerobic fermentations in airtight polybag and after 10～15 days, be finished product, the fragrance that ripe fermentation material contains wine, odorless.

Product of the present invention, shows through the feeding trial of pig, with its albumen such as grade, replaces fish meal, to pig search for food and growth has no adverse reaction, feeding effect is identical, can reduce feed cost more than 8%.

(4), specific embodiments

The bacterial strain that the present invention adopts is commercially available manure fermentation agent.

Fresh 3 kilograms of mixing of 7 kilograms, 90 kilograms of pigeon dungs, wheat bran, rice bran, the manure fermentation agent that adds 0.5 kilogram, adding water makes water content in 45～50% left and right, mix, tiling is to bamboo curtain splint, thickness of feed layer 15cm, first 32 ℃ of aerobic fermentations 15 hours, then proceeds in airtight polybag 45 ℃ and continues anaerobic fermentations and be finished product after 13 days.

Claims

1. utilize pigeon dung to produce a method for fermented-pig feed, it is characterized in that comprising the steps:

Fresh pigeon dung 90%, wheat bran 7%, rice bran 3% mix, add 0.5% manure fermentation agent, adding water makes water content in 45～50% left and right, mix, tiling is to bamboo curtain splint, thickness of feed layer 15～20cm, first 30～32 ℃ of aerobic fermentations 15～18 hours, then proceeds in airtight polybag 42 ℃～45 ℃ and continues anaerobic fermentations and be finished product after 10～15 days.
