The shortage of feed protein resources is a long-term situation faced by animal husbandry industry in China, and raw materials of feed protein usually account for a large proportion in animal diet, so formula cost is high. Therefore, the shortage of protein has not only become an crucial problem restricting the development of animal husbandry industry in China, but also an cause for the high cost of livestock and poultry production products. On the other hand, the low utilization rate of feed protein in animals will lead to the fermentation of undigested proteins in the hindgut and consequently produce harmful substances such as hydrogen sulfide, ammonia and cresol, which not only affect the intestinal health of animals, resulting in animal diarrhea, and reducing animal performance, but also aggravate the pollution to the environment. Improving the digestibility of feed protein is an vital measure to solve the above problems.
Adding protease to animal diet is one of the effective ways to improve the digestibility of feed protein. At present, proteases on the market can be roughly divided into three categories according to the optimal pH when they play a role, namely, acidic, neutral and alkaline proteases. However, there are some problems in the practical application of them, which greatly limits their application. The heat resistance of raw acid protease is poor, while the heat resistance of neutral and alkaline protease is slightly higher than that of the acid, but the acid resistance of those two is generally poor.
Thermostable Acid protease is a feed protease developed jointly by the Beijing Challenge Group Research Institute and the Feed Research Institute of the Chinese Academy of Agricultural Sciences(CAAS). The product is characterized by a remarkable improvement in heat resistance without coating and the like. The heat resistance of the water bath is significantly higher than that of similar products in the market. This product in practical application can obviously improve the digestion and utilization rate of the animal to the feed protein, improve the intestinal health, improve the production performance, and simultaneously reduce the feed cost and the pollution of the livestock and poultry excrement to the environment.
