Grass carp compound feed

Abstract

The invention discloses a grass carp compound feed which comprises the following nutrient components by mass percentage: 22-32 crude protein, 3-6 crude fat, 21-28 nitrogen free extract, 15-22 starch, 7-10 ash content, 6-10 water, 1.18-1.34 total phosphorus, 1.42-1.55 lysine and 5-8 crude fiber. The grass carp compound feed effectively solves the problems that in the existing grass carp culturing process, the protein conversion efficiency is low, the feed coefficient is high and a great deal of mesentery fat is accumulated, and improves the grass carp quality and edible proportion.

Description

technical field The invention relates to the field of grass carp feed, in particular to a 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 Grass carp (Ctenopharyngodon idella) is widely distributed in rivers in the northeast, east, central and southern regions of China. 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 the main freshwater aquaculture fish in my country. In 2006, the output reached 3.96 million tons, accounting for 21% of the total freshwater fish and shrimp aquaculture output (China Fisheries Yearbook, 2006). At present, the u...
