Calcareous invertase used for shrimp feed and production technology thereof

Abstract

The invention relates to a feed used for aquaculture industry, in particular to a calcareous invertase used for shrimp feed and a production technology thereof. The invertase is characterized in that in terms of composition mixture rate, spirulina accounts for 30-55 percent, cerevisiae fermentum accounts for 10-20 percent, medical stone accounts for 10-20 percent and seaweed meal accounts for 20-30 percent. The invention has the beneficial effects as follows: by the technical proposal, the protein in the feed can be converted in the bodies of shrimps or other aquatic livestock, decomposed and then completely absorbed, thus promoting the growth speed of shrimps, enhancing the immunity and achieving strong disease-resistant ability and anti-stress ability as well as low feed coefficient.

Description

technical field [0001] The invention relates to feed for aquaculture, in particular to a calcium invertase for shrimp feed and a production process thereof. Background technique [0002] Shrimp, including various prawns, macrobrachium and grass prawns in freshwater culture and seawater culture, is a kind of aquatic product that people like. In addition to the delicious meat, its protein content is high, and the amino acids that make up the protein are balanced; the lipid content is low, and the cholesterol content of the edible part is lower. With the improvement of people's living standards and the growth of food nutrition requirements, the area of ​​prawn farming in my country is also increasing significantly, and the prawn farming industry is developing rapidly, but the level of feed production and technology research and development is far behind the development of the farming industry, especially The absorption and utilization rate of prawn feed is low, and the unabsorb...

Problems solved by technology

With the improvement of people's living standards and the growth of food nutrition requirements, the area of ​​prawn farming in my country is also increasing significantly, and the prawn farming industry is developing rapidly, but the level of feed production and technology research and development is far behind the development of the farming industry, especially The absorption and utilization rate of prawn feed is low, and the unabsorbed protein content in prawn excrement is too high, which damages the aquaculture water body and affects the growth of prawns. Growth speed and quality cause damage and other adverse consequences, which seriously restrict the normal development of China's shrimp industry

The shrimp farming industry is facing the dilemma of increasing risks and declining income, which has brought huge economic losses to farmers
