Problems solved by technology

[0002] Varieties such as Penaeus vannamei, Macrobrachium rosenbergii, Macrobrachium japonicus, river crab, and Procambarus clarkii have formed a relatively large scale of breeding in my country, and the production of pellet feed that matches them has also formed a large-scale production. The produced shrimp and crab pellet feed is directly processed by mixing the crushed raw materials in the pellet feed machine. The trypsin inhibitor in the soybean meal has a great influence on the protein absorption in the feed, which is not conducive to the improvement of the feed efficiency. improve
In addition, the conven...

Abstract

The invention relates to special shrimp and crab feedstuff added with fermented bean dregs and fermented fish meal and a production method thereof. The invention is characterized in that the method comprises the following steps: adding BGB biological bacteria into the bean dregs for fermentation; carrying out drying treatment on the fermented bean dregs; then, mixing the dried bean dregs with fish meal, sub powder, corns and alpha starch; carrying out ultramicro pulverization; mixing the pulverized materials with fish oil, phospholipids oil, calcium biphosphate, wall broken yeast and multivitamin premix compound for obtaining mixed materials; and sufficiently stirring the mixed materials to be prepared into grain feedstuff. The invention is favorable for the digestive absorption of shrimps and crabs on protein, can improve the nutritive value of the feedstuff, can improve the nutritive quality of vegetable protein in the bean dregs, and is favorable for reducing the disease rate of the shrimps and the crabs and enhancing the cultivation ecological stability. Because of the addition of the wall broken yeast with the obvious food calling effect, the utilization rate of the feedstuff can be improved, and the invention is favorable for lowering the feedstuff factors. When being used for the shrimp and crab cultivation, the invention has the characteristics of fast growth, low cultivation cost, high cultivation yield and good economic benefits.

Description

technical field [0001] The invention relates to a feed formula for economical shrimp and crabs, in particular to a special feed for shrimps and crabs added with fermented soybean meal and fermented fish meal and a production method thereof. Background technique [0002] Varieties such as Penaeus vannamei, Macrobrachium rosenbergii, Macrobrachium japonicus, river crab, and Procambarus clarkii have formed a relatively large scale of breeding in my country, and the production of pellet feed that matches them has also formed a large-scale production. The produced shrimp and crab pellet feed is directly processed by mixing the crushed raw materials in the pellet feed machine. The trypsin inhibitor in the soybean meal has a great influence on the protein absorption in the feed, which is not conducive to the improvement of the feed efficiency. improve. In addition, the conventional pellet feed currently produced has problems such as poor food-attraction and low nutrient absorption r...
