Compound feed for ctenopharyngodon idella

Abstract

The invention discloses a compound feed for ctenopharyngodon idella. The compoound feed for ctenopharyngodon idella comprises the following nutrient components in percentage by mass: 22-33% of crude protein, 3-6% of crude fat, 36-50% of starch, 7-10% of ash, 6-10% of water, 1.18-1.34% of total phosphorus, 5-8% of raw fiber and 0.2-1.55% of crystallized nonessential amino acid. The compound feed for ctenopharyngodon idella has the advantages of effectively improving the body weight gain rate of ctenopharyngodon idella, increasing conversion rate of the feed, increasing deposition rate of protein, reducing fat accumulation of mesentery, improving the quality and edible proportion of ctenopharyngodon, saving culture cost greatly and improving economical benefits.

Description

technical field [0001] The invention relates to the field of grass carp feed, in particular to a novel compound feed capable of improving the growth and protein deposition rate of grass carp and reducing feed coefficient, liver system coefficient and whole fish fat. Background technique [0002] grass carp( Ctenopharyngodon idella ) are widely distributed in rivers and rivers in the northeast, east, central and southern regions of my country. Since the successful hatching in 1958 by artificial oxytocin insemination, grass carp has been introduced to various parts of the world in recent decades, such as Japan, Southeast Asia, Eastern Europe, and the United States, and has become a highly valued freshwater cultured fish. Grass carp is the second most productive fish in the world, and it is also the main freshwater aquaculture fish in my country. In 2009, the output reached 4.081 million tons, accounting for 18% of the total freshwater fish aquaculture production (China Fisher...

AI Technical Summary

Problems solved by technology

[0003] At present, the use of compound feed in aquaculture production practice often leads to problems such as low protein conversion efficiency, high feed coefficient, and a large amount of fat deposition in grass carp mesentery, which not only increases the feed cost of grass carp farming, but also leads to a great waste of resources and seriously affects the quality of grass carp. quality, reducing the edible ratio of grass carp, and causing a certain degree of damage to the environment
