Problems solved by technology

In daily feeding, if the feeding amount is too low, the shrimp will be in a semi-starved state, and the growth and development will be slow; if the feeding amount is too high, not only the feed utilization rate will be low, but also the water quality will be deteriorated, diseases will be caused, and death will be caused.

Embodiment 1

[0022] Prepare 10kg feed, its raw material composition: (imported) 110 parts of fish meal, 240 parts of soybean meal, (imported) 120 parts of rapeseed meal, 120 parts of peanut meal, 210 parts of flour, 60 parts of rice bran, 20 parts of soybean oil, 30 parts of shrimp bran powder , 28.5 parts of calcium dihydrogen phosphate, 38 parts of squid paste, 10 parts of allicin, 1.5 parts of dehusk, 2 parts of bacillus, 10 parts of premix, phytase 1000IU / kg.

[0023] The fishmeal, soybean meal, rapeseed meal, peanut meal and rice bran are first pulverized respectively, passed through a 60-mesh sieve, then superfinely pulverized (98% of the particle size can pass through 80 mesh), and mixed twice to form a large mixed material D1; Then the shelling element, shrimp bran powder, calcium dihydrogen phosphate, squid paste, allicin, bacillus, and premix are mixed uniformly to form a mixed material D2, and then the large material D1 and the mixed material D2 are mixed and enlarged step by ste...

Embodiment 2

[0025] Growth test: Procambarus clarkii was provided by Lukou base of Jiangsu Freshwater Fisheries Research Institute. Shrimp that are healthy, of the same size and weight are selected for the test, and the initial average weight of each individual is about 3.02g. Randomly divided into groups, with a control group (feeding commercial feed) and a test group (feeding the above-mentioned compound feed), each group set up 3 parallel experiments, 50 test shrimps in each parallel group, a total of 6 cement ponds (2.50m × 2.5 m×0.8m). After 7 days of domestication, the shrimps were fed with the feed of the control group and the experimental group. After the 60-day breeding experiment, the indicators of growth and immunity were measured.

[0030] The results showed that: compared with the commercial feed of the control group, the experimental group significantly increased the weight gain rate of shrimp by 17.26%, and reduced...

Embodiment 3

[0039] Prepare 10kg feed, its raw material composition: (imported) 130 parts of fish meal, 220 parts of soybean meal, (imported) 140 parts of rapeseed meal, 100 parts of peanut meal, 200 parts of flour, 70 parts of rice bran, 30 parts of soybean oil, 32 parts of shrimp bran powder , 25 parts of calcium dihydrogen phosphate, 30 parts of squid paste, 6.3 parts of allicin, 1.7 parts of shelling factor, 3 parts of bacillus, 12 parts of premix, phytase 1500IU / kg.

Abstract

The invention discloses environment-friendly type compound feed of young procambarus clarkii and a feeding method of the environment-friendly type compound feed. In the feed, (imported) fish meal, soybean meal, (imported) rapeseed meal, peanut meal and the like are used as protein raw materials, so that the requirements on amino acids of the procambarus clarkii are met, the utilization rate of the protein is improved and the emission of nitrogen is reduced; the efficiency of the feed is improved and the cost is reduced; inkfish cream, allicin and the like are added so that the feed has a certain food calling effect; the utilization rate of baits by the procambarus clarkii is improved and wastes are reduced; and additives including bacillus, phytase and the like are added so that the feed has the effects of regulating intestinal microorganism flora, improving digestion and absorption of phosphorus and the like. The selected raw materials have sufficient sources, a production process is simple and the feed is not easy to go bad and is convenient to transport and preserve.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to an environment-friendly compound feed for juvenile Procambarus clarkii and a feeding method thereof. Background technique [0002] Procambarus clarkii (Procambarus clarkii), commonly known as "crayfish", belongs to the class Cmstacea, the order Decapoda, the family Cambaridae, and the genus Procambarus. It is the most important freshwater crayfish in the world today. Shrimp farming species, whose output accounts for 70% to 80% of the whole crawfish output, is also an important economic aquaculture object in my country at present, and the scale and density of farming are expanding year by year. However, with the increase of breeding density, the residual bait and metabolic waste also increase. A large amount of nitrogen, phosphorus, sulfur, copper and other elements in the manure of farmed animals pollute the sediment and water sources; the dissolved oxygen in the water body decreases, and...
