Abstract

The invention relates to the technical field of feed and particularly discloses a juvenile crab feed. The feed consists of the following raw materials in parts by mass: 25-35 parts of fish meal, 22-28 parts of dehulled soybean meal, 3-5 parts of squid liver paste, 20-25 parts of casein, 4-6 parts of fish oil, 15-25 parts of peanut meal, 6-10 parts of shrimp head powder, 5-7 parts of phospholipid oil, 3-7 parts of complex vitamins for crabs, 0.5-1.5 parts of trace elements for crabs, 2-3 parts of glycine, 2-3 parts of vegetable oil, 0.2-0.6 part of phytase additive, 0.1-0.5 part of shelling element, 0.06-0.08 part of phagostimulant, 12-24 parts of zeolite and 2-5 parts of juvenile crab precocity inhibiting feed additive. Due to the adoption of the technical scheme of the invention, the juvenile crab feed has the beneficial effects that the juvenile crab feed is comprehensive in nutritional ingredients, reasonable in composition proportion and safe and reliable in use. Moreover, a ratio of precocious young crabs is obviously reduced, a survival rate of breeding the juvenile crabs into young crabs is improved, a use amount of the feed is reduced, and the acre yield of the young crabs is greatly improved.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to feed for young crabs. Background technique [0002] Crab seedlings refer to crab larvae in the megalopa stage that can be used for breeding and production. They are divided into megalopa, bean crab, and button crab. Generally speaking, crab seedlings refer to button crab seedlings, which are raised from the third stage to the end of the year. Or the crab species in the spring of the following year, the general size of the pond is 50-200 per kilogram. The shape of button crab seedlings is similar to that of adult crabs. Its individual growth is fast, the number of moulting times is high, and its metabolism level is high. It requires an environment with abundant aquatic plants, fresh water quality and sufficient bait. The individual growth difference among juvenile crab populations is very significant. Under natural conditions, the individual difference of crab seedlings at the same ...
