Description

Method for washing and disinfecting empty houses of brooding cages

Technical Field

The invention belongs to the technical field of henhouse disinfection, and particularly relates to a method for washing and disinfecting an empty house of a brooding cage.

Background

Currently, the closest prior art:

in a breeding community under the feeding mode of 'all-in all-out', the management of the vacant shed period is an important method and means for reducing and killing potential bacteria, viruses and parasites in the breeding shed, cutting off the longitudinal propagation path of pathogenic microorganisms between the chicken flocks of the previous batch and the next batch, and providing safety guarantee for the chicken flocks of the next batch. However, most farmers in chicken farms lack the concept of empty shed management and do not pay attention to cleaning and disinfection operations in the empty shed management period, and even if some farmers manage empty sheds, the problems that the disinfection mode is single, only the air disinfection is paid attention to, and the cleaning and disinfection of feeding equipment, drinking water and auxiliary facilities are not paid attention to exist frequently. Many farmers lack scientific and rigorous epidemic prevention consciousness in the management period of the vacant house, and have thin sterile concept, thereby not only causing feeding environment pollution and pathogenic microorganism diffusion. Many times the outbreak of chicken flocks is caused by the failure of farmers to properly disinfect the flock during the shed management period.

In summary, the problems of the prior art are as follows:

most farmers in chicken farms have single disinfection mode in the management period of the chicken coop, the cleaning and sanitation mode is not scientific and thorough, and all problems can be solved only by considering the disinfection, but the excrement and the chicken feathers carrying the chicken flocks in the previous batch easily cause environmental pollution and pathogenic microorganism diffusion to cause the fulminant diseases of the chicken flocks.

The difficulty of solving the technical problems is as follows:

as most farmers do not have scientific and reasonable house flushing disinfection methods, the flow is not emphasized, the chicken house is not cleared up and directly flushed, and some farmers are easy to cause unqualified empty house disinfection due to improper equipment use.

The significance of solving the technical problems is as follows:

the complete empty shed management thoroughly solves the problem of batch-to-batch transmission, provides a stable environmental foundation for the health of the next batch of chicken flocks, and provides the most basic guarantee for the next batch of chicken flocks to be sick.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a method for washing and disinfecting an empty shed of a brooding cage.

The invention is realized in this way, and the method for washing and disinfecting the empty shed of the brooding cage specifically comprises the following steps:

1) cleaning before washing: arranging articles in a production area, intensively cleaning excrement, lifting a seasoning plate, cleaning dust, and tightly wrapping various circuit devices by using plastic cloth;

2) washing the henhouse: washing sequentially from outside to inside and from front to back, washing twice from top to bottom, washing a central fecal zone and a sewage pool, washing a clean channel and a material tower in front of a house, and washing a dust-settling chamber and a sewage channel in back of the house;

3) chicken house arrangement and disinfection: 0.2% of all-purpose classical or Repu pesticide is applied in the henhouse for thoroughly spraying and disinfecting, drinking water pipes are disinfected, caustic soda is used for soaking manure ditches for disinfecting, drying is carried out after disinfection is finished, and fumigation and disinfection are carried out after drying;

4) sterilizing a production area: cleaning a road, keeping a neutral position, cleaning a sewage way, spraying 2% of hot and alkaline water to the field area, and continuously spraying for 4 days, 1 time/day and 2 vehicle water/day;

Further, in the step 1), when dust is cleaned, the dust is cleaned from top to bottom and from front to back.

Further, in the step 3), the henhouse is disinfected for four times, the henhouse is disinfected by the glutaric dialdehyde disinfectant, the bulrush disinfectant, the iodine preparation, the quaternary ammonium salt and the bulrush disinfectant (before fumigation) for the third time;

for the first disinfection, 0.4 percent of rapamicide is used for thorough spraying disinfection, and each time, 800 kg of water is used;

the second disinfection is carried out by spraying 0.3 percent iodine preparation thoroughly, and each time, 400 kg of water is used;

for the third disinfection, 0.2 percent quaternary ammonium salt disinfectant is used for thoroughly spraying disinfection, and each time, 400 kg of water is used;

the fourth disinfection is carried out by thoroughly spraying 0.1 percent of rapamicide before fumigation, and each time, 300 kg of water is used.

Further, in the step 3), the disinfection of the drinking water pipe is carried out for three times,

for the first time: after the group transfer is finished, soaking for 48 hours for the first time by 200ppm ohm, and washing by clear water;

and (3) for the second time: drinking water pipe laying hen field can overturn the drinking water pipe, and chick field drinking water pipe can not overturn in the cage, can directly use the poling pipe ware to thoroughly clear up, carries out the second soaking 48 hours with 60ppm ohm, and clear water washes:

and thirdly: before fumigation, the mixture is soaked for a third time for 48 hours by using 40ppm of ohm and washed by clean water.

Further, in the step 3), drying is carried out for more than 7 days during drying, drying is carried out at 40 ℃ in winter, and drying is carried out in summer in an air exhaust mode.

Further, in the step 4), cleaning the channel comprises firstly burning the chicken feather, cleaning the garbage and washing the garbage; the neutral position comprises weeding, loosening the soil, cleaning garbage and scattering quicklime; the sewage cleaning channel comprises manure cleaning, road surface washing, open ditch and septic tank.

The invention also aims to provide a brooding cage house for implementing the epidemic prevention and disinfection method for the brooding cage house.

In summary, the advantages and positive effects of the invention are: the washing and disinfecting method provided by the invention can effectively cut off the longitudinal spread of diseases, make the management of the empty houses of the breeding farm well, and ensure that the problems of the chickens in the previous batch cannot be spread to the next batch. The chickens can not be sick, so that the quality of the chickens is guaranteed, the chickens do not need to be dosed, and the cost of veterinary drugs is reduced; the chicken colony quality is good, all production indexes can also play a stable role, and the death and culling rate is reduced.
