Problems solved by technology

At present, most of the pellet feeds produced have problems such as poor food attraction, low feed utilization rate and unsatisfactory breeding effect.
Due to the existence of the above-mentioned defects, the survival rate and output of the existing Procambarus clarkii artificial culture are all low, and the scale effect of cultivation is not very obvious

Abstract

The invention relates to a special feed containing shell-broken yeast powder for procambrus clarkia and a production method thereof, which is characterized by mixing and producing soybean meal, fish meal, wheat middling, corn and bond after being smashed with fish oil, phospholipids oil, calcium biphosphate and multi-dimension pre-mixed material, and the shell-broken yeast powder is added to be adequately stirred the uniformly-mixed materials are cured by steam inside a conditioner and is squeezed by a granulating machine to granulated feed, and the granulated fed is packed to obtain the finished product after being dried and cooled. The shell-broken yeast powder with remarkable food calling effect and high nutrition value is added, so the utilization rate of the feed can be improved, the production cost can be reduced, and the culture yield and the culture benefit can be increased; and moreover, the special feed has the advantages of less waste, fast growth of the shrimp postlarvae, high culture yield and good economic benefit after feeding the procambrus clarkia.

Description

technical field [0001] The invention relates to a feed formula for freshwater economical shrimps, in particular to a special feed for Procambarus clarkii added with broken-wall yeast powder and a production method thereof. Background technique [0002] Procambarus clarkii is native to North America and is commonly known as freshwater crayfish. It belongs to Arthropoda, Crustacea, Decapod, and Cricketidae in classification. It was introduced to my country in 1929 and has become one of the main freshwater species in my country. Therefore, the development of nutritious artificial feed has attracted widespread attention of the industry. Due to the poor foraging ability of Procambarus clarkii, the artificial pellet feed fed by them is extremely wasteful, and it has become an urgent task to improve the food-attractiveness of the special feed for Procambarus clarkii. At present, most of the pellet feeds produced have problems such as poor food attraction, low feed utilization rate ...
