As the temperature gradually increased, the growth rate of microorganisms accelerated with the increase of temperature. The addition of potassium diformate in the chicken diet improved the antibacterial activity, reduced the nutritional competition of microorganisms to the host, and reduced the incidence of bacterial infection.

The most suitable temperature for laying hens is 13-26 ℃. The continuous high temperature will cause a series of heat stress reactions in animals.

 The consequence of the decrease of food intake: when the food intake decreases, the intake of energy and protein decreases correspondingly. At the same time, due to the increase of drinking water, the concentration of digestive enzymes in the intestine decreases, and the time of chyme passing through the digestive tract shortens, which affects the digestibility of nutrients, especially the digestibility of most amino acids, to a certain extent, thus affecting the production performance of laying hens. The main performance is that the egg weight decreases, the eggshell becomes thin and brittle, the surface is rough, and the broken egg rate increases. The continuous reduction of feed intake will lead to the decline of resistance and immunity of chickens, and even a large number of deaths. Birds can not recover by themselves. It is necessary to ensure that the growth environment is dry and ventilated, and it is also necessary to promote the absorption of feed nutrients in time to improve the resistance of animals to diseases.

The function of potassium diformate is as follows

1. Adding potassium diformate to feed can improve the intestinal environment of animals, reduce the pH value of stomach and small intestine, and promote the growth of beneficial bacteria.

2. Potassium dicarboxylate is an antibiotic substitute approved by European Union, and it has the function of antibacterial and growth promoting agent. Dietary potassium diformate can significantly reduce the contents of anaerobes, Escherichia coli and Salmonella in the digestive tract, and improve the resistance of animals to diseases.

3. The results showed that 85% potassium diformate could pass through the intestines and stomach of animals and enter the duodenum in a complete form. The release of potassium dicarboxylate in the digestive tract was slow and had a high buffer capacity. It could avoid the excessive fluctuation of acidity in the gastrointestinal tract of animals and improve the feed conversion rate. Because of its special slow-release effect, the acidification effect is better than other commonly used Compound Acidifiers.

4. The addition of potassium diformate can promote the absorption and digestion of protein and energy, and improve the digestion and absorption of nitrogen, phosphorus and other trace elements.

5. The main components of potassium dicarboxylate are formic acid and potassium formate, which exist naturally in nature and animals. They are ultimately metabolized into carbon dioxide and water, and have complete biodegradability.
