Compound feed for promoting young giant salamander growth at larval stage

Abstract

The invention discloses a compound feed for promoting young giant salamander growth at a larval stage. The compound feed comprises a first component and a second component, wherein the first component comprises the following raw materials in parts by weight: 20-25 parts of earthworm, 11-14 parts of tadpole, 5-10 parts of freshwater shrimp, 15-20 parts of acete chinensis, 12-15 parts of silkworm chrysalis, 5-8 parts of grub, 15-18 parts of bean worm, 19-22 parts of maggot, 15-20 parts of wiggler, 7-10 parts of water flea, 8-11 parts of loach, 2-4 parts of crucian fries and 2-4 parts of grass carp fries; and the second component comprises the following raw materials in parts by weight: 60-70 parts of fish meal, 10-15 parts of fermentation peanut meal, 5-10 parts of fermentation soya bean meal, 16-19 parts of egg white, 7-9 parts of casein, 7-9 parts of oleum morrhuae, 2-3 parts of vitamin, 2-4 parts of a mineral substance, 2-4 parts of sodium alginate, 0.5-1 part of probiotic, 3-5 parts of medicated leaven, 3-5 parts of astragalus membranaceus, 3-5 parts of poria cocos, 1-3 parts of herba leonuri, 1-3 parts of rhizoma atractylodis macrocephalae, 1-2 parts of ligusticum wallichii, 6-8 parts of hawthorn fruits, 3-4 parts of liquorice, 3-5 parts of radix stemonae, 2-4 parts of radix isatidis and 1-3 parts of cyrtomium fortunei.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed for promoting the growth of giant salamander larvae. Background technique [0002] Giant salamander, commonly known as giant salamander, is a national second-class protected animal. Its meat is delicious, but artificial breeding has always been difficult. Among them, the larvae of giant salamanders mainly feed on red nematodes, small fish and shrimps, water fleas and aquatic insect larvae. Feed is a feeding method, but there are many defects in the feed of this feeding method: 1. 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; 2. The immature production technology makes the production cost higher, and the output and quality are difficult to control; 3. The nutrition is single, the composition distribution is unreasonable, an...
