Formula of micro-particle feed for young phase of giant salamander

Abstract

The invention discloses a formula of a micro-particle feed for a young phase of a giant salamander. According to the formula, raw materials are as follows in parts by weight: components comprise 24-26 parts of whole egg yolk powder, 7-9 parts of casein, 37-39 parts of fish meal, 4-6 parts of soya bean meal, 6-8 parts of egg white, 7-9 parts of cod liver oil, 2-4 parts of vitamins, 2-4 parts of mineral substances, 1-2 parts of sodium alginate, 2-3 parts of lecithin, 0-1 part of cholesterol and 1-2 parts of an enzyme preparation. According to the formula of the micro-particle feed for the young phase of the giant salamander, a reasonable feed formula is formulated according to researches of feeding habits, nutrition physiology and nutrition requirements of young giant salamanders; the raw materials are selected and living giant baits are partially or wholly replaced, so as to get rid of the disadvantage situation depending on natural baits; the addition and the utilization of the enzyme preparation and the lecithin are attended specially and the loss of nutritional ingredients in the processing process is considered.

Description

technical field [0001] The invention specifically relates to a microparticle feed formula for giant salamander larvae. Background technique [0002] Giant salamander juveniles mainly feed on red nematodes, small fish and shrimps, daphnia and aquatic insect larvae. At present, the bait for artificial feeding of giant salamander larvae is mainly red nematodes or compound feeds. Lots of flaws: Natural food organisms are easily affected by natural resource fluctuations and seasonal climate changes, such as abundant sources in a certain period and relatively scarce in another period, The immature production technology makes the production cost higher, and the output and quality are difficult to control. It is not easy to disperse in water, and it is easy to cause water pollution, resulting in giant salamander poisoning. Single nutrition, unreasonable distribution of ingredients, Poor appetite for giant salamanders. Contents of the invention [0003] The technical prob...

Problems solved by technology

[0002] Juvenile giant salamanders mainly feed on red nematodes, small fish and shrimps, water fleas and larvae of aquatic insects. The feeding method is compound feed, but there are many defects in the feed of this feeding method: Natural food organisms are vulnerable to natural resource fluctuations, seasons The impact of climate change, such as abundant sources in one period and relatively scarce in another period, immature production technology, etc. make production The cost is high, and the output and quality are difficult to control. is not easy to disperse in water, and it is easy to cause water pollution, resulting in giant salamander poisoning.Single nutrition, unreasonable distribution of ingredients, Poor food attractant for giant salamander
