A kind of triangular bream mixed feed and preparation method thereof
Technical field
The present invention relates to the aquatic feeds technical field, especially a kind of triangular bream mixed feed and preparation method thereof.
Background technology
Triangular bream (Megalobrama terminalis Richardson) popular name tower bream, triangle bream, black bream, the flat chest triangular bream of formal name used at school, be subordinate to Osteichthyes, Cypriniformes, Cyprinidae, triangular bream Abramidinae, triangular bream belong to, be the famous economic freshwater fish of China, mainly be distributed in the coastal all water systems in the middle and lower reach of Yangtze River, the Yellow River, Heilungkiang and east, and, be commonly called as " Qiantang River tower bream " to originate from the most famous of the Qiantang River; The triangular bream build is attractive in appearance, the little back of the body is high, slightly triangular in shape, have that growth is fast, feeding habits wide, resistance is strong, characteristics such as the body pork is thick, spur is less, meat is soft, rich in protein, be subjected to liking of consumers in general deeply, be that a kind of throwing people is few, the more valuable economic fish that output is big has vast potential for future development.
In recent years, breakthrough along with triangular bream artificial propagation techniques, seed rearing technology, its consumption demand and cultured area constantly enlarge, develop into good aquaculture new varieties gradually in Hang-jia-hu, Shaoxing, Quzhou, the area, Jinhua in Zhejiang Province, especially good owing to culture benefit in district cities such as Xiaoshan, area, Hangzhou, Tonglu, Fuyang, Chunan, fisherman's breed enthusiasm is high, and cultured area increases year by year.
Do not have good production and exploitation about the triangular bream mixed feed at present, in the triangular bream breeding process, people can only culture triangular bream with other fresh-water fishes mixed feed, cause cultured output, meat quality and economic benefit reduction in the triangular bream breeding process, a large amount of wastes of feed resource, human resources and fund have not only been caused, simultaneously, also can cause very big negative effect to culturing the waters water environment, be not inconsistent with culture fishery development trend efficient, green, environmental protection, be unfavorable for the healthy sustainable development of triangular bream aquaculture industry yet.
Summary of the invention
Purpose of the present invention will solve the deficiency that above-mentioned technology exists just, and provide a kind of young soft-shelled turtle with expanded pellet diet and preparation method thereof, this feed formula is balanced in nutrition, the raw material mix collocation rationally, select the raw materials such as fish meal, meat meal tankage and dregs of beans of high-quality for use, satisfy the triangular bream nutritional need, improve food conversion ratio, reduce aquaculture cost, satisfy the demand of ecologic breeding simultaneously, reduce the discharging of nitrogen, phosphorus, thereby reduce water pollution, for the development of triangular bream aquaculture brings considerable economic and environmental benefit.
The present invention solves the technical scheme that its technical problem adopts: this triangular bream mixed feed, formulated by following raw materials in parts by weight: fish meal 10-20 part, meat meal tankage 4-10 part, flour 20-24 part, dregs of beans 10-20 part, peanut meal 5-10 part, dish dregs of rice 10-20 part, rice bran 5-10 part, fish oil 1-2.5 part, calcium dihydrogen phosphate 1-2 part, B B-complex 0.8-1.5 part, mineral matter 0.5-1.0 part.
Concrete prescription is as follows: 19 parts of fish meal, 4 parts of meat meal tankages, 22 parts in flour, 16 parts of dregs of beans, 6 parts of peanut meals, 16 parts of the dish dregs of rice, 8 parts in rice bran, 2 parts in fish oil, 1.2 parts of calcium dihydrogen phosphates, 1.1 parts of B B-complexes, 0.7 part in mineral matter; 15 parts of white fish meals in the fish meal wherein, 4 parts of red fish meals.
Concrete prescription is as follows: 17 parts of fish meal, 9 parts of meat meal tankages, 21 parts in flour, 17 parts of dregs of beans, 5 parts of peanut meals, 17 parts of the dish dregs of rice, 8 parts in rice bran, 2 parts in fish oil, 1.2 parts of calcium dihydrogen phosphates, 1.1 parts of B B-complexes, 0.7 part in mineral matter; 13 parts of white fish meals in the fish meal wherein, 5 parts of red fish meals.
Concrete prescription is as follows: 18 parts of fish meal, 10 parts of meat meal tankages, 21 parts in flour, 18 parts of dregs of beans, 5 parts of peanut meals, 15 parts of the dish dregs of rice, 9 parts in rice bran, 1.9 parts in fish oil, 1.3 parts of calcium dihydrogen phosphates, 1.1 parts of B B-complexes, 0.7 part in mineral matter; 12 parts of white fish meals in the fish meal wherein, 5 parts of red fish meals.
The preparation method of triangular bream mixed feed of the present invention, the preparation method is: the preparation method of product is: with fish meal, meat meal tankage, flour, dregs of beans, peanut meal, the dish dregs of rice, rice bran material, by above-mentioned processing compound, pour in the receiving slit, pass through elevator, material is removed impurity through receiving sieve and pipe magnetic separator, enters mixer and mixes for the first time, and the material that mixes is pulverized by meal machine and micronizer; Enter second drum mixer, add B B-complex and the mineral matter of proportioning this moment, mixes, and granulates through bulking machine, dries through dryer, and screening sprays into grease then, the cooler cooling, and sieve classification is finished product.
Fish meal, meat meal tankage, dregs of beans, peanut meal, the dish dregs of rice provide different forage protein source, fat source for triangular bream from different raw material mix in this prescription, while is in conjunction with the food calling and the effect that fat source is provided of fish oil, the feed nutrition that allows the present invention produce is complete, the nutrition unbalanced phenomena of avoiding the single feed raw material to bring, the feed food calling effect that the present invention is produced is better.
The present invention compared with prior art, useful effect is:
1, the present invention forms in that the nutritional need of triangular bream is comprehensively studied the basis, has experiment basis and scientific basis widely.
2, by having determined the nutritional need of triangular bream, select the protein of high-quality, fatty raw material and feed addictive efficiently for use, design the triangular bream feed formula of amino-acid, fatty-acid balance, comprehensive nutrition, this food conversion absorptivity height, pollutant are drained less, the triangular bream fast growth.
3, simultaneously according to the improvement of existing production technology, reduce the loss of feed nutrient in process, will lose control as far as possible in minimumization.
4, the production technology of mixed feed of the present invention belongs to the production field of expanded pellet diet, is convenient to large-scale production, is the fast development of triangular bream aquaculture, brings considerable benefit.
