Problems solved by technology

Among the vannamei shrimp (body length 3cm and above) is the period of fastest growth and development, if the juvenile shrimp feed is used again, the nutrition will be excessive and waste, causing water pollution. If the nutrition cannot keep up with the demand, the growth rate will not keep up. No, affect economic benefits
And today's Penaeus vannamei feed mainly uses animal protein, especially fish meal, and less vegetable protein is used.

Embodiment 1

[0031] The percentage by weight of each component of the best formulation of shrimp feed formula in Penaeus vannamei adopts:

[0032] Imported steam fish meal 6.2, imported direct fire fish meal 9, domestic fish meal 12, peeled soybean meal 20, peanut meal 12.5, fermented soybean meal 2.2, soybean protein concentrate 2.3, fermented cotton meal 2, flour 25.3, squid paste 2, fish oil 1, phospholipid oil 3. Calcium dihydrogen phosphate 1.5, choline chloride 0.18, betaine 0.2, multivitamin 0.1, multimineral 0.2, shelling protein 0.1, immune polysaccharide 0.1, antioxidant 0.02, antifungal agent 0.1.

[0033] Weigh the above-mentioned components according to the percentage, mix them thoroughly, and carry out superfine grinding. It is required that 80% pass through the 80-mesh standard sieve. Feeding Penaeus vannamei medium shrimp.

Embodiment 2

[0035] The weight percent of each component of the shrimp feed formula in the Penaeus vannamei of the present invention can be adopted:

[0036] Imported steam fish meal 10, imported direct fire fish meal 6, domestic fish meal 11.2, peeled soybean meal 15, peanut meal 10.6, fermented soybean meal 4, soybean protein concentrate 4, fermented cotton meal 3, flour 26.1, squid paste 3, fish oil 1.5, phospholipid oil 2. Calcium dihydrogen phosphate 2, choline chloride 0.1, betaine 0.4, complex vitamin 0.2, complex mineral 0.26, chitin 0.2, immune polysaccharide 0.2, antioxidant 0.04, antifungal agent 0.2.

[0037] The preparation method is the same as that of Example 1.

Embodiment 3

[0039] The weight percent of each component of the shrimp feed formula in the Penaeus vannamei of the present invention can be adopted:

[0040] Imported steam fish meal 8, imported direct fire fish meal 8, domestic fish meal 15, soybean meal 18, peanut meal 8, fermented soybean meal 3, soybean protein concentrate 3.5, fermented cotton meal 3, flour 22, squid paste 4, fish oil 2, phospholipid oil 1.5, Calcium dihydrogen phosphate 2.5, choline chloride 0.2, betaine 0.3, multivitamin 0.16, multivitamin 0.14, chitin 0.2, immune polysaccharide 0.27, antioxidant 0.03, antifungal agent 0.2.

[0041] The preparation method is the same as that of Example 1.

[0042] Using the above feed formula, the white prawns were fed by the satiation method, and the white prawns (average body weight 2.15g / tail) were divided into the experimental group and the control group (conventional feed was used), and the daily feeding amount (kg / 10,000). Tail): 0.25-2.20, daily feeding times: 4 times, feedi...

Abstract

The invention relates to a mixed feed for middle-sized penaeus vanname. The mixed feed comprises, on the basis of weight percentage, 5 to 10 of imported steamed fish meal, 5 to 10 of imported direct-fired fish meal, 10 to 15 of domestic fish meal, 10 to 20 of dehulled soybean meal, 5 to 15 of peanut meal, 1 to 5 of fermented soybean meal , 1 to 5 of soy protein concentrate, 1 to 5 of fermented cotton meal, 20 to 30 of flour, 2 to 4 of cuttlefish paste, 1 to 2 of fish oil,1 to 3 of lecithin oil, 1.5 to 3 of calcium dihydrogen phosphate, 0.1 to 0.3 of choline chloride, 0.2 to 0.4 of betaine, 0.1 to 0.2 of composite vitamin, 0.1 to 0.3 of a composite mineral matter, 0.1 to 0.3 of chitin, 0.1 to 0.3 of immune polysaccharide, 0.02 to 0.05 of an anti-oxidant and 0.05 to 0.2 of a mildew inhibitor, totaling a weight percentage of 100. The mixed feed for middle-sized penaeus vanname prepared in the invention is applicable to penaeus vanname with a body length of no less than 3 cm and has the advantages of good palatability, long duration of resistance to water soaking and easiness in digestion; with the mixed feed, a fast growth speed and a high survival rate of penaeus vanname, little feed waste, small water pollution and a low feed coefficient are realized.

Description

technical field [0001] The invention relates to a shrimp feed, and more particularly to a feed formula for shrimp in Penaeus vannamei. technical background [0002] Penaeus vannamei, whose scientific name is Penaeus vannamei, is one of the three largest species of farmed shrimp in the world. It was originally distributed in Central and South America, and the sub-Asian waters of the Pacific Ocean. Because of its thin shell and fat body, fresh and tender meat, and rich nutrition, it is favored by consumers, and the breeding volume is increasing year by year. Especially after the desalination farming of Penaeus vannamei, the geographical restrictions were broken, and the farming range gradually expanded from the coast to the inland, and the farming area increased significantly with the improvement of people's consumption level. Penaeus vannamei is cuddly food and takes a long time to eat, so the requirements for feed are resistance to soaking, sinking to the bottom, soft but...
