Britain is already crazy with heat! People jumped into the Thames. What are the effects of high temperature weather on farmers?

Since this summer, the whole world has been experiencing hot weather. Hot weather is unbearable not only for people, but also for animals, and the influence of hot weather on farmers is also very serious. High temperature weather, especially for chicken farms, is facing various heat stress effects, which, if left untreated, will quickly lead to heatstroke and a large number of deaths of laying hens. ?

Can animals get heatstroke?

Yes, animal heatstroke is called heat stress state, and neuroendocrine activities have changed obviously, especially the secretion of cortical hormone and thyroid hormone. In the short term, the body temperature rises, the plasma concentrations of corticosteroids and thyroid hormones increase obviously, the abnormal metabolic activity increases, the body temperature rises, and the body temperature rises in the short term. If the hot weather lasts for a long time, due to the atrophy of thyroid and adrenal gland, hormone secretion decreases. Due to the change of hormone level in the body, the electrolyte concentration in body fluid fluctuates, which affects the acid-base balance and leads to a series of physiological and pathological changes.

How to improve poultry pens in hot weather?

In order to ensure a good thermal insulation effect, you can choose the appropriate layout of the external wall and roof structure. You can install awnings when it is hot in summer. Vines and shade trees can also be planted around the hedge. Use fans, curtains, spraying, watering and other methods to cool the equipment, strengthen the ventilation and heat dissipation of the wall, avoid surface water, control the humidity in the enclosure, and improve the poultry feeding conditions. ?

Why do poultry suffer from heatstroke?

Because of the high body temperature and vigorous metabolism of poultry, and the lack of sweat glands in poultry itself, the continuous high temperature will increase the body temperature of poultry, and because the feathers are thick and hairy, the heat is not easy to dissipate, so the ability to avoid heatstroke is poor. If we don't pay attention to cooling and heatstroke prevention in hot summer, birds will have accelerated breathing, increased drinking water and decreased appetite, which will affect the growth rate and egg laying rate, and even heatstroke or even death in severe cases, resulting in poor breeding benefits. Therefore, we need to take the following measures to reduce the possible economic losses during the high temperature period.
