Mixed feed required by nutrition of young Chinese soft-shelled turtles with weight between 150g and 250g and preparation method

Abstract

The invention discloses a mixed feed required by nutrition of young Chinese soft-shelled turtles with weight between 150g and 250g and a preparation method, the mixed feed comprises the following raw materials by weight: 30-40 parts of flour, 20-30 parts of fresh feed, 2-5 parts of hemoglobin powder, 8-12 parts of seasonal fresh vegetables, 10-15 parts of starch, 4-8 parts of yeast powder, 2-5 parts of garlic powder, 1-2 parts of immunopolysaccharide, 1-2 parts of mineral matter trace element, 0.5-0.8 part of composite vitamin, 0.5-1 part of probiotics, 1-2 parts of salt and 1-2 parts of amino acid. The mixed feed provided by the invention has the advantages of balanced and comprehensive nutrition, and good palatability, the young Chinese soft-shelled turtle fed by the feed has characteristics of good growth, strong disease resistance ability, fast growth speed and high weight gain rate, compared with the present eel feed or self compounded feed, the weight gain of the feed provided by the invention is faster by 1.6-2.4 times, so that the culture period for young Chinese soft-shelled turtles is substantially shortened, the great enhancement of the culture efficiency of the young Chinese soft-shelled turtles can be promoted and the yield per unit area can be increased.

Description

technical field [0001] The invention relates to a compound feed for young soft-shelled turtles weighing 150 grams to 250 grams and a preparation method for the compound feed. Background technique [0002] Chinese soft-shelled turtle (turtle), as a nutritious and healthy aquatic product, is deeply recognized and loved by consumers. With the continuous increase of demand, the output of natural soft-shelled turtle in the past can no longer meet the demand. In recent years, the breeding scale of Chinese soft-shelled turtle has been expanding day by day, and aquatic feed products have also emerged in an endless stream. However, there are few special feeds for soft-shelled turtles. Because the rise and scale of the soft-shelled turtle industry are not as good as other fish, such as eels, for a long time, young soft-shelled turtles have no special feed, but eel feed has to be used instead. Practice has proved that due to long-term consumption of eel feed alone, soft-shelled turtl...

Problems solved by technology

However, the soft-shelled turtle feed ingredients that are simply prepared by themselves are unreasonable and unbalanced in nutrition. There are the following disadvantages in feeding soft-shelled turtles with it: one is that it is easy to cause the diseases of soft-shelled turtles to occur continuously, the survival rate decreases, and the mortality rate remains high; The finished Chinese soft-shelled soft-shelled turtle has an ugly appearance, slow growth, and a long breeding cycle; third, the cost of feeding is high, the waste of feed is large, and the water body is polluted, which greatly reduces the nutritional value and commercial value of the soft-shelled soft-shelled turtle; fourth, many additives Unclear, the nature of vitamins is unstable, and the salinity is slightly high, and the use alone cannot meet the needs of the special growth stage of juvenile soft-shelled turtles; fifth, the feed is not easy to preserve and easily deteriorates, so it must be used immediately when used, and it is not suitable for large-scale breeding
