In modern feed processing production, the full price of feed nutrients and the balance among various nutrients have been gradually paid attention to, and dietary nutrition has tended to be scientific. In addition to feed nutrition, feed intake and digestion and absorption are two important factors that ensure animal health and efficient production. With the development of society and economy and the improvement of people's living standards, the demand for livestock products will increase, and the aquaculture industry will be required to play a higher level of efficiency. As the feed intake of livestock and poultry is limited, especially the weaning stress response of sow pigs, the response of prenatal and postnatal physiological changes of sows, all affect the normal production level. In addition, the constants and trace elements, mineral feeds, vitamins, drugs, and antioxidants that are added to compound feeds are increasing, as well as the unpleasant tastes produced by the application of leftovers in agricultural and sideline products, light industry, and food industries. The natural flavor of the feed has a great influence, which greatly reduces the palatability of the formulated feed. The pig's taste and smell are very sensitive, which in turn leads to a decrease in the pig's feed intake. Therefore, it is necessary to add feed flavors to compound feeds.
Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-Containing Phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
