Feed additive for improving body shape of large yellow croaker and application of feed additive

Abstract

The invention provides a feed additive for improving the body shape of a large yellow croaker. The feed additive comprises the following components in parts by weight: 2 to 4 parts of polygonum multiflorum, 3 to 5 parts of sealwort, 6 to 10 parts of rhizoma alismatis, and 8 to 12 parts of fructus psoraleae. According to the feed additive provided by the invention, the body shape of the large yellow croaker can be improved effectively; the fat deposition of the large yellow croaker is reduced; the defect that the large yellow croaker which is bred by a feed is short and small in body shape is changed.

Description

technical field

[0001] The invention relates to the field of feed additives, in particular to a feed additive for improving the body shape of large yellow croaker and its application. Background technique

[0002] Large yellow croaker belongs to the order Perciformes, the family Scrotoaceae, and the genus Yellow croaker, commonly known as cucumber fish, red melon, yellow croaker, yellow croaker, etc. It is a warm-temperate offshore fish that migrates in clusters, and is mainly distributed in the southern Yellow Sea, the East my country Sea and the South China Sea. Wait for the sea area. Its meat is delicious, and it is one of the traditional valuable seawater economic fish in my country. Since the 1980s, artificial breeding and breeding have been successful. At present, a large yellow croaker industry with an annual production of more than 100,000 tons and an output value of over 7 billion yuan has been formed in my country. The large yellow croaker is now among the largest ...

Examples

Embodiment 1

[0021] As a preferred solution, weigh Polygonum multiflorum 4kg, Polygonatum 5kg, Alisma 8kg, Psoralen 12kg, ferrous sulfate 2kg, copper sulfate 3kg, calcium dihydrogen phosphate 5kg, bentonite 61kg. Pulverized by an ultrafine pulverizer, all passed through a 200-mesh sieve, mixed uniformly and added to the large yellow croaker compound feed in a proportion of 0.2%.

Embodiment 2

[0023] As a preferred solution, weigh Polygonum multiflorum 2kg, Polygonatum 3kg, Alisma 10kg, Psoralen 8kg, ferrous sulfate 2kg, copper sulfate 5kg, calcium dihydrogen phosphate 4kg, bentonite 66kg. After being pulverized by an ultra-fine pulverizer, all of them pass through a 200-mesh sieve, mixed evenly, and then added to the large yellow croaker compound feed at a ratio of 0.3%.

Embodiment 3

[0025] As a preferred solution, weigh Polygonum multiflorum 3kg, Polygonatum 4kg, Alisma 6kg, Psoralen 10kg, Ferrous sulfate 4kg, Copper sulfate 2kg, Calcium dihydrogen phosphate 6kg, Bentonite 65kg. After being pulverized by an ultra-fine pulverizer, all of them pass through a 200-mesh sieve, mixed evenly, and then added to the large yellow croaker compound feed at a ratio of 0.3%. Example 4
