preparation example Construction

[0027] Preparation of the Bacillus lateralosporus preparation: inoculate the Bacillus lateralosporus on the above-mentioned culture medium, culture at 37° C. with shaking at 200 rpm, and spray-dry the preparation after most of the Bacillus lateralosporus forms spores. Each gram of Bacillus lateralis preparation contains 1×10 Bacillus lateralis 11 more than cfu.

[0028] The pad material is composed of chaff and sawdust, and the chaff and sawdust are composed in a volume ratio of 2-5:5-8. The litter is required to be free from mildew and insects.

[0029] During the brooding stage, about 10 litter materials are laid in the chicken house, and the mixture of litter materials and chicken manure cleaned up after the brooding stage is brooding chicken manure. Compared with using cornmeal or meat chaff as nutrients, the use of brooding chicken manure can reduce the investment cost of the farmer's fermentation bed. At the same time, the brooding chicken manure is fresh and mildew-fr...

Embodiment 1

[0032] Medium formula for cultivating Bacillus lateralosporus (g / L): corn starch 10; bran 10; corn steep liquor 18; (NH 4 ) 2 SO 4 1.5; 2 HPO 4 1.5; MgSO 4 2.0; CaCO 3 0.5; pH 7.0. After 15 minutes of autoclaving, the culture medium was inoculated with spores of Bacillus disspora. Spray-drying is carried out after most of the Bacillus lateralosporus in the culture medium form spores to prepare the Bacillus lateralosporus preparation.

[0033] During the brooding stage, about 3 cm of litter material is laid, and the brooding chicken manure cleaned up after the brooding stage is used for pre-fermentation. The litter material consists of chaff and sawdust in a volume ratio of 4:6.

[0034] The pre-fermentation litter is composed of litter material and brooding chicken manure in a volume ratio of 4:1, mixed evenly, inoculated with Bacillus lateralis, adjusted to 50% moisture, and pre-fermented in a hill shape of not less than 1 meter 6 sky. The inoculum amount is 1g B...

Embodiment 2

[0038] Medium formula for cultivating Bacillus lateralosporus (g / L): corn starch 8; bran 8; corn steep liquor 15; (NH 4 ) 2 SO4 1.0; Na 2 HPO 4 1.0; MgSO 4 1.0; CaCO 3 1.0; pH 7.0. After 15 minutes of autoclaving, the culture medium was inoculated with spores of Bacillus disspora. Spray-drying is carried out after most of the Bacillus lateralosporus in the culture medium form spores to prepare the Bacillus lateralosporus preparation.

[0039] During the brooding stage, about 5 cm of litter material is laid in the chicken coop, and the brooding chicken manure cleaned up after the brooding stage is used for pre-fermentation. The litter material consists of chaff and sawdust in a volume ratio of 5:5.

[0040] The pre-fermentation litter is composed of litter materials and brooding chicken manure in a volume ratio of 3:1, mixed evenly, inoculated with Bacillus lateralis, adjusted to a moisture content between 40%, and pre-fermented in a hilly pile of no less than 1 meter...

Abstract

The invention relates to a bacillus laterosporus fermentation bed and a manufacturing method thereof. The manufacturing method of the fermentation bed comprises the steps that padding raw material and chicken manure are evenly mixed according to the volume ratio of 3-5:1, bacillus laterosporus preparations are inoculated, the water content ranges from 40% to 60%, and accumulation preliminary fermentation is conducted for 5-7 days; the preliminary fermentation padding material is laid in a barton, then padding raw material having the same thickness as the preliminary fermentation padding material is laid on the preliminary fermentation padding material, the fermentation bed is manufactured after the padding raw material and the preliminary fermentation padding material are evenly mixed, the water content of the fermentation bed ranges from 30% to 60%, and the total thickness of the fermentation bed ranges from 8cm to25cm; the padding raw material is composed of chaff and saw dust according to the volume ratio of 2-5:5-8. According to the bacillus laterosporus fermentation bed, the thickness of the padding raw material is small, the usage amount of the padding raw material is little, the workload of a farmer is greatly reduced, and cost is saved. At high temperature, the effect is still good, mosquitoes and other insects can be restrained and killed, the intestinal function of bird species is improved, egg white, starch, fat and fecaluria are efficiently degraded, and ammoniacal odour and stink are little. The bacillus laterosporus fermentation bed is convenient to use and enlarge, and disinfection can be conducted while chickens exist.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, in particular to a fermentation bed for poultry breeding and a manufacturing method thereof. Background technique [0002] The fermentation bed is an environmentally friendly, safe and effective ecological breeding method proposed by using a new natural agricultural concept combined with modern microbial fermentation treatment technology. [0003] Fermentation beds are mainly used in the breeding of livestock, such as pigs. For example, the Chinese invention patent with the authorized announcement number CN 102090346B discloses a microbial bedding fermentation bed, which includes two layers, the upper layer has a thickness of 30 to 40 cm, and includes 30% to 70% sawdust and 30% to 30% by weight. For 70% chaff, add 5 to 10kg of washed rice bran and 50 to 200g of Bacillus subtilis environmental protection bacterial agent into the mixture per cubic meter, mix and ferment, control the water...
