Description

A convenient broiler house for heatstroke prevention and cooling

technical field

The utility model belongs to the technical field of chicken house environment control in animal husbandry and veterinary feeding, and in particular relates to a broiler house which is convenient for heatstroke prevention and cooling.

Background technique

Broiler houses are mainly divided into two categories: open chicken houses and closed chicken houses. Open chicken coops, also known as ordinary chicken coops, are characterized by: all or most of the chicken coops are ventilated by natural air flow, the general stocking density is low, natural lighting, day and night light time changes with the seasons , Sherwin rises and falls with the seasons. The advantages of open chicken coops are simple process, energy saving, low cost and low investment. In the case of playgrounds and green feed, the requirements for feed are not very strict, and chickens can only move frequently, with strong adaptability and physical fitness. Robust; its disadvantages are: due to open management, the physiological status and production performance of chickens are greatly affected by external environmental conditions, and the possibility of chickens being infected with diseases through various channels such as insects, soil, birds, and air increases. Chickens are limited.

Closed chicken house, also known as airtight chicken house, the roof and walls of the chicken house are well insulated, and the environment inside the chicken house is adjusted by manual or instrument control to create an "artificial climate" to make it as close as possible to the physiological function of the chicken body. Optimal conditions to maximize broiler performance. With the development of the chicken industry, the degree of standardization and scale is getting higher and higher. Closed chicken houses have become the mainstream of broiler farming. Its advantages are reflected in: 1. Intensification and high degree of standardization. The number of chickens raised in a single house is generally more than 10,000, the number of chickens raised per unit area is large, the land utilization rate is high, the growth of chickens can be controlled according to the feeding standards, and the products meet the national standards; 2. The environmental conditions are easy to control. Through manual control technology, the chicken house environment is stable, meets the physiological and production needs of chickens, is not easily disturbed by natural environmental conditions, is conducive to the growth and health of chickens, and is convenient for chicken quality monitoring; 3. Save labor and reduce feeding costs. The temperature, light, ventilation, humidity, and even drinking water, feeding, and epidemic prevention operations of the closed chicken house can be mechanized, electronic, and automated, reducing the labor required for production, reducing production costs, and improving production efficiency; Fourth, it is convenient for the prevention and control of chicken epidemics. Closed chicken coops are better isolated from the outside world and are not easily invaded by external pathogenic microorganisms. At the same time, the disinfection and sterilization in the chicken coop can be controlled in a certain space, and the chance of cross-contamination is small, which is conducive to the prevention and control of epidemic diseases, especially major animal diseases.

The excellent performance of the closed chicken house promotes the rapid development of large-scale broiler breeding enterprises. The disadvantages of the high-density feeding method are beginning to appear, and the harm of high temperature and heat stress to chickens is becoming more and more serious. Increased drinking water, accelerated breathing, increased body temperature, decreased nutrient digestibility, growth retardation, decreased feed utilization, decreased productivity, increased disease, decreased chicken quality, increased culling rate and mortality, etc., have caused serious damage to the chicken industry. Heatstroke prevention and cooling of chicken coops has become an objective problem that the broiler farming industry must deal with.

There are many methods for heatstroke prevention and cooling in chicken coops, mainly including the following three: one is spray cooling operation, using artificial or mechanical methods to spray atomized water droplets in the livestock breeding house. This method has limited cooling effect and high humidity. There may even be water on the ground; the second is the fan cooling method, which replaces the outdoor cold air with the high-temperature air in the chicken house to achieve the purpose of cooling. This method has a poor cooling effect when the outdoor temperature is high, and the fan causes The air convection of the broiler chickens is easy to catch a cold, and the ventilation and cooling will also reduce the humidity in the chicken house, which is not conducive to the health of the chickens; the third is the negative pressure water curtain cooling method, and its equipment mainly includes porous wet curtains, water circulation systems and exhaust fans. Due to the negative pressure, the unsaturated outdoor air flows through the porous and moist surface of the wet curtain. When the fan draws air, the cold air cooled by the wet curtain is continuously introduced into the room, so as to achieve the cooling effect. Negative pressure water curtain cooling method is the most widely used and effective heatstroke prevention and cooling method in current production practice. However, due to the unreasonable structure of the chicken house, it will also cause uneven temperature, cold air inlet, and hot end. Chickens exposed to humidity, cold, and forced wind speed for a long time are prone to respiratory diseases. However, the wind speed near the exhaust fan is high, and the chickens grow slowly and are underweight.
