Black carp feed added with shell powder and manufacturing method thereof

Abstract

The invention discloses a black carp feed added with shell powder. The black carp feed is characterized by being prepared from the following raw materials in parts by weight: 17-21 parts of shelled corn, 12-14 parts of polished glutinous rice, 5-7 parts of starch, 9-12 parts of duck meat, 8-10 parts of duck livers, 16-19 parts of bran, 17-21 parts of rice bran, 20-25 parts of soybean meal, 6-9 parts of shell powder, 5-9 parts of oyster meat powder, 6-9 parts of prawn powder, 14-17 parts of birch branches, 17-19 parts of poplar branches, 0.2-0.4 part of table salt, 3-4 parts of lard, 4-6 parts of addition agents, and an appropriate amount of water. According to the black carp feed disclosed by the invention, various components are effectively mixed, so that the nutrition of the black carp feed is comprehensive, and the influence of nutrition resistant factors in the soybean meal on the growth of fishes is reduced. The shell powder is added into the feed, so that the calcium content of the feed is effectively supplemented, and the meat quality of black carps is delicious. If the black carps are fed with the feed for a long term, the survival rate of the black carps can be increased, and the attack rate of the black carps is reduced, so that the economic benefits of raising households are further improved.
