Bird feathers are thick and have no sweat glands and are highly susceptible to high temperatures. With the increase of temperature, the feed intake of chickens decreased, and a series of physiological indicators were affected. As a result, the production performance of broilers decreased and mortality increased. In the past two years, due to the hot climate, the phenomenon of heat stress is more common and the losses caused by it are even greater. During the hot season, proper adjustment should be made from the nutritional level to reduce the loss of heat stress.
Adjust diet formulas. During the hot season, broilers lost appetite and their feed intake decreased. It is generally believed that summer broilers should be fed with high-protein feeds to ensure the nutritional needs of broiler chickens. This is not the case. This is because broilers can quickly meet the nutritional needs of broilers after they have rapidly ingested high-protein diets, and then broilers are less willing to eat or even refuse to feed, resulting in insufficient energy feed intake for broilers, which in turn is not conducive to the growth and development of broilers. . Conversely, if you raise the energy level of the broiler feed and reduce the protein level in the broiler feed, the broiler must have no more than enough feed to meet the protein requirements to meet the protein requirement of the broiler, which makes the broiler more Ingestion of energy feeds increases the body weight of broilers, which is a much better result than raising the protein content of broiler feeds.
Adjust the feeding times. When the ambient temperature is too high, the number of feedings may be appropriately reduced. The general practice is to stop feeding once during the hottest time of the day and try to use the early morning or nighttime feeding to reduce the body temperature and increase the utilization of the feed.
Regulates acid-base balance in the body. During the hot season, the body's breathing is accelerated to expel excess heat from the body. As a result, a large amount of carbon dioxide is excreted, the acid-base balance is destroyed, and the blood ph value is increased. In severe cases, hypokalemia and respiratory intoxication occur. Solution: You can add 0.15% or 0.3% potassium chloride, or 0.25% citric acid, or 0.5% to 1% calcium chloride or 0.25% potassium chloride to your diet. .
Increase vitamin levels. When broilers are under heat stress, increasing dietary vitamin levels can effectively help broilers to get hot. The commonly used heat-stress-resistant vitamin is VC, and 200 mg of VC is added per litre of drinking water. Add sedatives and antibiotics.
In heat stress, in order to reduce unnecessary activity and energy consumption of muscles, sedative drugs are often used to inhibit central nervous system and body muscle activity to reduce the effects of heat stress. Adding antibiotics to beverages can prevent and treat diseases, increase daily weight gain and improve feed conversion rates, and increase gastrointestinal absorption.
Other methods. To ensure that broilers drink cold water, feeding cool feed such as roots, tubers, and melons can also reduce heat stress.
