Microbial fermentation bed pig raising method

Abstract

The invention discloses a microbial fermentation bed pig raising method comprising the following steps: selecting a sunny ventilating place to build a pigpen; selecting branches or straws to fill a padding pit, filling saw dusts mixed with microbial fermentation strains into the padding pit, and covering a plastic film for fermentation; placing piglets into the pigpen according to spacing of 1pig / 1.5 sq.m; feeding the piglets 3 times a day, moving the pig excretive faece into a concentration zone in every 5 days, mixing the faece with the padding, and burying the mixture into the padding pit; moving female pigs into a nursing ring after fertilization for farrowing, and moving the mother pigs to other nursing rings after milking for 28 days; keeping the piglets in the original nursing ring to grow another 30 days, and moving the piglets into a feeding ring when the body weight grows to 35-45 jin, and feeding the piglets for 90-105 days before slaughter; moving the faece into the concentration zone, uniformly mixing the faece with new padding, and burying the mixture into the padding pit; mixing partial the removed old padding into the new padding so as to catalyze microbial strain breeding, and applying the rest old padding into filed as a quality microbial organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of pig raising, in particular to a method for raising pigs in a microbial fermentation bed. Background technique [0002] The breeding of pigs has a long history in our country, which can be traced back to ancient times. For a long time, the method of raising pigs one by one has not changed. In modern times, although large-scale pig farm breeding methods have been adopted, the overall feeding methods have not changed much. In the 1980s, a mechanized factory breeding method was introduced. This method uses steel frame feeding beds, automatic supply of drinking water and feeding, which has significantly improved the feeding efficiency and pork quality. But there are obvious deficiencies in this method: the first is that the energy consumption is very large, especially the water consumption is very large, and a large amount of water and electricity are needed to flush the ring bed every day; Digestion treatme...

Problems solved by technology

But there are obvious deficiencies in this method: the first is that the energy consumption is very large, especially the water consumption is very large, and a large amount of water and electricity are needed to flush the ring bed every day; Digestion treatment, therefore, the smell around the pig farm is so bad, mosquitoes and flies are rampant, which seriously pollutes the environment

Third, when young pigs are weaned and transferred from the sow bed, it is particularly easy to cause piglet weaning syndrome due to due payment, which greatly affects the growth and development of young pigs

Fourth, the activities of sows in the positioning pen are restricted, the amount of exercise is reduced, and diseases such as hoof cracks are prone to occur.

In this way, the entire fermentation bed breeding process of pigs can only be staged breeding, which affects the overall benefit of pig breeding
