Giant salamander feed

Abstract

The invention discloses a giant salamander feed, which belongs to the technical field of aquaculture . The technical point of the giant salamander feed is that the giant salamander feed consists of soy protein concentrate, cottonseed cakes, meat and bone powder, bran, rice bran, vegetable oil, vitamins, amino acid, spermatogenic powder, mycotoxin adsorbent and monocalcium phosphate. The content and components of protein in the soy protein concentrate, the cottonseed cakes and the meat and bone powder in the feed formula are suitable for the growth and development of giant salamanders, the sources of the materials are wide, the giant salamander feed is environment-friendly, and the addition of the mycotoxin adsorbent enhances the immunity and resistance of the animal, decreases the incidence of induced diseases, and increases the growth speed of the giant salamanders; the incidence of enteritis is decreased in the process of culture; the shelf life of the feed is prolonged, and the feed is not deteriorated yet after being stored for 18 months. The process of a method for preparing the giant salamander feed is simple, parameters are easy to control, and the giant salamander feed is suitable for industrialization.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and relates to a fish feed, more specifically to a salamander feed, in particular to a salamander feed and a preparation method thereof. Background technique [0002] Salamander, scientific name Chinese Giant Salamander, belongs to Amphibians, Cauraceae, Cryptobranchidae, and is a national second-class protected animal. Salamander is a freshwater species, burrowing species, mostly distributed in inaccessible and basically non-polluted natural environment, adults like to "lonely", juveniles like to live in groups, and have self-mutilation. Its life span is mostly between 40 and 50 years, and can be as high as 130 years. The feeding of salamanders belongs to the type of "waiting for avoidance", and some take the initiative to feed. Their main food is fish, shrimp, earthworms, crabs and small insects. They are extremely resistant to hunger. Generally, if they do not eat for 2 to 3 months, their...

[0004] Guangdong Yingrui Biotechnology Co., Ltd. disclosed an artificial feed for freshwater carnivorous fish and its preparation method on March 25, 2015. The publication number is CN104431417A, which includes the following components: fish meal, yellow powder, raw bran, soybean meal, Calcium dihydrogen phosphate, squid paste, fish oil, phospholipid oil, premix, antimicrobial peptides, bacillus, and the prepared industrial feed is wrapped with a capsule shell. The components of this invention are all commonly used components, and they are not special formulas for giant salamanders. , in addition, the preparation process is to fill the prepared mixture into the capsule shell, the process is complicated, and there are defects such as high feed production cost, short shelf life, and the shell fish is difficult to digest
