[0002] Lobster meat is delicious, with high protein content and easy digestion. It is a very popular food and has become an important species of freshwater aquaculture in my country. The market demand is large, and excellent lobster feed can effectively improve the quality of lobster; Traditional lobster feed mostly pays attention to the output of lobster, but ignores the physical and chemical environment of the cultured water body, resulting in high mortality rate of raised lobsters, ...

Abstract

The invention discloses a lobster feed with high conversion rate capable of purifying water and improving meat quality. The lobster feed is prepared from the following raw materials in parts by weight: 6-8 parts of meat powder, 4-6 parts of wheat middling, 3-4 parts of water caltrop, 4-5 parts of Chinese knotweed herb, 3-5 parts of spirulina, 20-26 parts of sweet potato skin, 5-8 parts of saw dust, 3-5 parts of oyster meat powder, 12-16 parts of fried soybean meal, 1-2 parts of salt, 4-6 parts of cuttlefish meal, 2-4 parts of pagoda leaf powder, 6-8 parts of rice sprouts, 6-9 parts of dry arenicola cristata powder and 6-10 parts of an assistant. The lobster feed disclosed by the invention is high in conversion rate; the added raw materials such as the oyster meat powder and dry arenicola cristata powder are rich in a plurality of proteins and amino acids, so that metabolism can be effectively promoted; the immunity of the lobsters can be enhanced by contained unsaturated fatty acid; and the raised lobsters are extremely high in nutrient value, and significant in economic benefits.

[0016] Specific implementation plan
[0017] The present invention will be further described in detail below in conjunction with the following specific embodiments:
[0018] Weigh the following parts by weight (kg) of raw materials: Meat Meal 7, Sub-Flour 5, Potamogeton 3, Fotan Mother 4, Spirulina 4, Potato Skin 23, Sawdust 7, Oyster Meat Meal 4, Fried Soy Flour 14, Table Salt 1 , Squid powder 5, Sophora japonica powder 3, Gu Ya 7, dry earthworm powder 8, additives 8;
[0019] The additives are made of the following parts by weight (kg) of raw materials: polyacrylamide 0.02, phytase 3, taurine 2, prickly pear 7, bentonite 1, amino acid chelated calcium 2, amino acid chelated iron 2, Amino acid chelated zinc 2, bamboo vinegar liquid 1, lotus house 5, tapioca starch 14, pottery clay 5, trifolium sylvestris 3; the preparation method is to mix the prickly pear, lotus house, and trifolium sylvestris to crush and squeeze the pulp to obtain the slurry For standby, the bamboo vinegar liquid is distilled at 60°C, the obtained distillate is condensed and collected, and then the second distillation is performed at 90°C again. The obtained distillate is collected for use, and the polyacrylamide, phytase, and taurine , Bentonite, amino acid chelated calcium, amino acid chelated iron, amino acid chelated zinc, tapioca starch, pottery clay, and the mixed slurry and distillate obtained above are put into a high-speed mixer, mixed at 550 rpm for 5 minutes, and then taken out. After drying, it is placed in a pair-roll extrusion granulator to make granules.
[0020] The specific steps of preparing the lobster feed are as follows:
[0021] (1) Mix the meat meal, secondary meal, fried soybean meal, salt, squid meal, spirulina, yam peel, and sawdust in a fermentation tank and aerobic fermentation at 50°C for 8 days to obtain fermented materials;
[0022] (2) Mix oyster meat powder, Potamogeton crispus, hot charcoal mother, locust leaf powder, grain sprouts, dry earthworm powder, auxiliaries and remaining materials in a mixer and mix them evenly;
[0023] (3) Put the products obtained in step 1 and step 2 into a twin-screw extrusion granulator for granulation. The conditions of the granulator are the screw speed of 270 rpm and the temperature is controlled at 50°C;
[0024] (4) Microwave drying the particles obtained in step 3, control the moisture content of the particles at 16%, and pack them into bags.
[0025] In order to further illustrate the application value of the present invention, the implementer divided 2000 lobsters into the experimental group and the control group according to the principle of the same age, weight, health status, and sex ratio. 1000 lobsters in each group were put into lobster farming. Breeding in the pond, the experimental group was fed the lobster feed of the present invention, and the control group was fed the traditional lobster feed. The feeding and management methods were the same. The initial and the end of the lobster weight were recorded, and the lobster health and feeding conditions were observed. The following results were obtained:
[0026] Group Control group (traditional feed) Experimental group (invented feed) Experiment time (days) 60 60 Initial average weight (g) 7.5 7.6 End average weight (g) 23.7 26.9 Bait factor 2.41 1.75 Case fatality rate (%) 9.6 5.3
[0027] It can be seen from the data in the table that the weight of the lobsters using the feed of the present invention is obvious, and the water quality of the breeding pond is clear, there is no turbid foam, etc., and the mortality of lobsters is significantly reduced compared with the control group.
