Low fishmeal feed for final grow-out period of carassius auratus gibelio and preparation method thereof

Abstract

The invention relates to a low fishmeal feed for the final grow-out period of carassius auratus gibelio and a preparation method thereof, and belongs to the technical field of aquatic formula feeds. The preparation method comprises the following steps: grinding fish meal, blood powder, soybean meal, rapeseed meal, cottonseed meal, flaxseed cake, sesame seed meal, bran, flour, rice bran, vegetable oil, premix for fish, bile salt, 50% choline chloride, attapulgite, non-starch polysaccharide enzyme, lysine, methionine, forsythia fructus extract, monocalcium phosphate and potassium sorbate mildew preventive, uniformly stirring and mixing the powders; grinding the mixture into a mixed material by virtue of a grinder; and finally preparing pelletized feed by utilizing a conventional pelletized feed method. The low fishmeal feed for the final grow-out period of carassius auratus gibelio is comprehensive and rich in nutrition, and can be used for improving the immunity of carassius auratus gibelio, improving stress, reinforcing disease resistance, improving feed palatability and promoting growth.

Description

technical field [0001] The invention belongs to the technical field of aquatic compound feed, and in particular relates to a low-fishmeal feed used in the later stage of growing heterogeneous gibel crucian carp and a preparation method thereof. Background technique [0002] Allogenetic gibel carp (Carassius auratus gibelio) is the offspring of Founder gibel crucian carp with natural gynogenesis as female parent and Xingguo red carp as male parent through artificial insemination. It has the characteristics of good heterosis, obvious effect of increasing production, tender meat, rich nutrition, long survival time out of water, wide appetite, easy feeding, strong adaptability, and survival rate. The main species in China is one of the bulk freshwater fish in China. It is very popular among farmers and consumers. The aquaculture output is increasing year by year. In 2012, the national crucian carp aquaculture output was about 2.45 million tons, which played a very important role...

(2012) applied for a patent (201010117179.X) for a safe compound feed for heterogeneous gibel carp; Xiao Ling et al. (2013) applied for a patent (201010117179.X) for a special compound for heterogeneous gibel carp Feed and its preparation method; Yin Xiaoling (2013) applied for a patent (201310259439) for a heterogeneous gibel crucian carp feed for protecting the liver and gallbladder and its production method. The fish body is immune and grows, but the total amount of fishmeal used in the compound feed exceeds 10%, which makes the feed cost too high
