Temperature has a great influence on chicken production performance. The suitable production temperature for laying hens is 13 - 23 °C and the temperature exceeds 30 °C. The egg production rate drops significantly. If the temperature exceeds 35 °C, some chickens will die of heat stroke. At the same time, high temperatures cause the quality of the Eggs to decrease, and soft shell eggs and shelled eggs increase. High temperatures are also detrimental to the growth of broiler chickens, resulting in reduced feed intake, reduced weight gain, and reduced meat quality.
The low temperature will increase the maintenance requirements, increase the feed intake, increase the feed-to-egg ratio and feed-to-meat ratio, so the winter temperature should not be lower than 7 °C. Many chicken farmers only consider feeding the diet that meets the breeding standards according to the breeding requirements of the breed, and often do not consider seasonal and temperature changes, and cannot adjust feed formulas in time, resulting in wastage of feed.
Chicks have a poor ability to regulate body temperature and a small range of adaptation to the ambient temperature. Therefore, the temperature of chicks within 7 days of age is required to be controlled at 32-35°C, after which the temperature gradually decreases. If the temperature is too high or too low, it will affect the diet, activity and rest of the chicks, resulting in poor absorption of the yolk of the chicks, decreased resistance to disease, retarded growth, and even death.
Because adult chicken lacks sweat glands, it has poor tolerance to high temperatures. When the ambient temperature is between 42 and 45 °C, adult chickens show mouth breathing, respiratory rate is accelerated, appetite is eliminated, drinking water is excessive, diarrhea is excreted, and the wings are outreached. Be restless. If it exceeds 45 °C, respiratory failure or even death may occur.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
