Abstract

The invention belongs to the field of aquaculture, and particularly relates to a fodder for breeding finless eels. The fodder comprises the following components in percentage by weight: 10-20 percent of bean pulp, 15-28 percent of goat blood powder, 10-25 percent of pork liver powder, 15-25 percent of fish powder, 5-10 percent of oat powder, 1-5 percent of earthworm powder, 5-10 percent of carrot powder, 0.1-0.5 percent of vitamin C, 0.02-0.08 percent of decavitamin, 0.5-0.8 percent of a finless eel phagostimulant and 0.1-0.5 percent of mineral substances. The fodder provided by the invention can be used for improving the balance of the nutrients; due to the use of a plurality of other added components, the finless eels can have enough vitamins and mineral substances; meanwhile, the fodder is added with the finless eel phagostimulant, so the attractive force of the fodder for the finless eels is increased, the utilization rate of the fodder is increased, and the growth rate of the finless eels is increased.

Description

A kind of feed of culturing rice field eel

Technical field

The invention belongs to aquaculture field, be specifically related to a kind of feed of culturing rice field eel.

Background technology

Swamp eel meat is satiny, delicious flavour, and not only protein, calcium, iron content surpass general fish.Modern medicine study shows, its vitamin A being rich in, lecithin, DHA, swamp eel ekmolin etc., there is the intelligence development of enriching blood, strong muscles and bones, mend the effect of brain and enhancing fitness, enhancement eyesight, the metabolism that promotes skin, recovery adjusting blood sugar physiological function, again because of fatty few, nutrition, medical value are very high, are the aquatic products dishes being loved by the people.Continuous expansion along with market demand, wild swamp eel cannot meet social demand, and during artificial feeding, feed should not be selected, swamp eel be take animal fodder as staple food, need to take in a large amount of protein-based food, but often use fish as feed, but fresh fishes should not preserve, and single food often causes the nutrition of swamp eel unbalanced, affect the speed of growth, and can impact the nutritive value of swamp eel.

Summary of the invention

The object of this invention is to provide a kind of balanced in nutritionly, and be convenient to the feed of the swamp eel that preserves.

The present invention is achieved through the following technical solutions:

A feed for culturing rice field eel, comprising: dregs of beans 10-20%, sheep blood meal 15-28%, pork liver powder 10-25%, fish meal 15-25%, oatmeal 5-10%, earthworm powder 1-5%, carrot meal 5-10%, vitamin C 0.1-0.5%, B B-complex 0.02-0.08%, rice field eel luring agent 0.5-0.8%, mineral matter 0.1-0.5%.

Preferably, in every 100mg mineral matter, containing 42.6mg calcium, 8.6mg iron, 4.3mg potassium, 3.6mg magnesium, 0.8mg molybdenum, 22.4mg sodium, 0.6mg copper, 2.1mg zinc, 6.8mg phosphorus, 1.6mg sulphur, all the other are other elements.

Oat reaches 15.6% containing thick protein, and fat 8.5% also has the elements such as starch release heat and phosphorus, iron, calcium, and the amino acid ratio of components of protein is more comprehensive.

Pork liver powder is the Powdered dry powder that pork liver is worn into after high temperature spray-drying, 100 grams, pork liver powder is containing 21.3 grams, protein, 4.5 grams, fat, 1.4 grams, carbohydrate, 11 milligrams of calcium, 270 milligrams, phosphorus, 25.0 milligrams of iron, 5.78 milligrams, zinc, 0.40 milligram of thiamine, Riboflavin Tetrabutyrate .11 milligram, 16.2 milligrams of niacins, 18 milligrams, ascorbic acid, the multiple nutritional components that contains swamp eel growth.

Sheep blood meal is that sheep blood is dried and obtains through low-voltage vacuum, and sheep blood meal main component is multiple proteins, is mainly hemoglobin, seralbumin, serum globulins and a small amount of fibrin.Still contain in addition the compositions such as the lipids such as a small amount of phosphatide, cholesterol and grape inorganic salts, be conducive to the growth of swamp eel.

Beneficial effect of the present invention: the present invention uses sheep blood meal, pork liver powder, fish meal, wormcast to coordinate dregs of beans to prepare ricefield el fodder as primary raw material, can provide a large amount of protein for swamp eel growth, simultaneously, different with content of mineral substances wherein due to the protein component in each raw material, improved the harmony of nutrition; Use other several adding ingredients, can provide enough vitamin and mineral matters for swamp eel, in feed, add rice field eel luring agent, improved the allure of feed to swamp eel, improved the utilization rate of feed, improved the swamp eel speed of growth simultaneously.

The specific embodiment
