Because of seasonal weather, broilers have stress reaction. How to deal with it?

With the development of intensive chicken industry, there are more and more stress factors, especially the normal stress in high temperature period, which exceeds the temperature regulation ability of broilers and produces a series of reactions, called heat stress. Under the condition of high temperature and high feeding density, heat stress is more common, normal immunity decreases, morbidity and mortality increase, which brings great losses to broiler breeding. So how to slow down the heat stress? Let's talk today.

Pay attention to the heat stress of drinking broilers, and the water consumption is an extremely important factor. More than 80% of the heat generated by broilers during heat stress is lost by evaporation, and drinking water can improve the survival rate. Increasing the intake of sodium chloride water or lowering the water temperature can alleviate the thermal stress response. The salt content of drinking water and drinking water temperature have obvious complementary effects. However, the temperature of drinking water is lower than the body temperature of broilers, and adding appropriate amount of salt can obviously improve the drinking water quantity and growth rate, and can well alleviate the heat stress.

Reduce the feeding density Before the arrival of high temperature season, some sparse grouping should be carried out according to reasonable feeding methods such as group transfer, combination and elimination, and appropriate feeding density should be arranged. Flat chickens should not be too large, and activities such as group transfer and transportation should be avoided as much as possible. If necessary, it should also be done on cloudy days or when the weather is cool in the morning and evening.

Fourth, strengthen ventilation, increase the ventilation of chicken houses, and reduce solar radiation. We can start with the building materials of the henhouse, use materials with good thermal insulation performance, hang the ceiling with fiberboard, paint the walls white, and plant trees and lawns around the henhouse. These measures are conducive to reducing the radiant heat from the outside into the henhouse. However, the intensification of modern chicken farms is more serious, so it is very important to prevent the heat stress of broilers in the process of ventilation and cooling in the house. The simplest ventilation method is the safety electric fan. When the house is below 40 degrees, increasing the wind speed is beneficial to the heat dissipation of chickens. In addition, the roof of the henhouse can be sprayed with water or spray atomization device to increase the evaporation and heat dissipation of the roof and alleviate the heat transfer from the roof to the house.
