current technology

Since entering the 1990s, China's livestock breeding industry has ushered in a good development opportunity. Livestock breeding is in the transition period from traditional extensive free-range to intensive large-scale breeding, and a number of standardized farms Rise. To achieve the industrialized development of China's aquaculture industry, there must be improved varieties, industrialized production of lexical materials, intensive breeding, systematic production management, scientific processing of meat products, and marketization of operations. Among them, the main limiting factors affecting the industrial development of China's aquaculture industry are low feed quality and low quality, which is prominently reflected in the lack of stable forage bases, insufficient feed grains, low quality, and lack of protein feed. Transfers, high prices and low quality, single varieties, lack of high-energy and high-protein concentrates, etc. are now made up of by-products from agricultural and sideline processing and sugar and wine processing.

On the other hand, in recent years, the current situation of China's sugar industry, especially the northern sugar industry, is worrying. Due to overproduction and low efficiency, sugar mill equipment has been idle for up to 7 months a year. This has emerged. On the one hand, the aquaculture industry urgently needs an industrialized grass product processing industry with high quality and high yield. On the other hand, the sugar industry, especially small and medium-sized sugar factories, has a large number of idle equipment. A better way out of the predicament.
