Shell solidifying mixed feed for penaeus monodon and preparation method thereof

Abstract

The invention discloses a shell solidifying mixed feed for penaeus monodon and a preparation method thereof. Raw materials of the feed consist of the following components in percentage by weight: 15-30 percent of fish meal, 5-10 percent of meat and bone meal, 1-5 percent of chiken meat meal, 1-5 percent of housefly larvae powder, 10-20 percent of fermented soybean meal, 10-15 percent of peanut bran, 1-5 percent of beer yeast, 1-5 percent of cuttlefish cream, 1-5 percent of shrimp head meal, 15-25 percent of strong flour, 1-5 percent of sea fish oil, 1-3 percent of soybean lecithin, 0.5-1.5 percent of calcium dihydrogen phosphate, 0.1-0.5 percent of calcium amino acid chelate, 0.1-0.5 percent of cholesterol, 0.01-0.1 percent of bacillus subtilis, 0.1-0.5 percent of spirulina powder, 0.1-0.5 percent of vitamin C-phosphate ester (35 percent), 0.05-0.1 percent of vitamin D3, 0.1-0.5 percent of composite multivitamins and 0.1-0.5 percent of composite mineral salt. The shell solidifying mixed feed for the penaeus monodon effectively meets the complete demand of the shrimps on nutritive materials at special stages of castoff and renew; the situations such as soft shell or failure of castoff of the shrimps are obviously improved; and the immunity of the penaeus monodon is obviously improved.

Description

technical field [0001] The invention relates to a feed, in particular to a shell-solid compound feed for Penaeus monodon and a preparation method thereof. Background technique [0002] Penaeus monodon (Penaeus monodon) is commonly known as grass shrimp, monodon shrimp, etc. At present, it is one of the three major shrimp cultured species in the world. With the continuous pursuit of yield and growth speed, growth problems such as soft shell or failure to molt often occur in the culture of Penaeus monodon. The emergence of these growth problems has an important relationship with the existing farming methods and feed formulation technology concepts. In the pursuit of growth speed, people often use the method of alternately injecting sea and fresh water to promote the molt and growth of Penaeus monodon. But at this time, the monodon prawns are not sensitive to protein, fat, sugar, etc., as well as vitamins (such as vitamin C, vitamin D, etc.). 3 etc.) and mineral elements (c...

Problems solved by technology

In the current prawn farming, such a formula concept is likely to cause insufficient nutrient supply during the special growth period of prawns or excessive nutrition during the normal growth period of prawns.
