Description

General-purpose high-efficiency extruded compound feed for young abalone

technical field

The invention relates to the field of aquaculture feed, in particular to a general-purpose high-efficiency puffed compound feed for young abalone.

Background technique

Abalone is a traditional precious seafood in our country. It is delicious and nutritious, and it is the top grade in the sea. Abalone meat is good for the intestines, nourishes yin and strengthens the kidneys; the shell has the function of improving eyesight and lowering blood pressure; extracting abalone III essence from abalone has obvious effects on inhibiting tumors, so it is both a nutritious food and a rare marine drug . In the past decade or so, due to the sharp decline in the output of major abalone-producing countries such as Australia, Japan, the United States, and Chile, the price in the international market has continued to rise. The market prospect is very broad. my country's artificial abalone farming industry began in the mid-1970s. After more than 30 years of development, abalone farming in Liaoning, Shandong, Fujian, Guangdong and other regions has become one of the pillar industries in coastal areas. Looking at the current status of abalone farming in my country, it can be said that it is developing rapidly and the results are gratifying, but we must also clearly see that there are still many problems in the breeding process such as water quality, bait, density, management, disease, etc., which restrict the continuous and stable abalone farming industry , Healthy development.

Contents of the invention

The purpose of the present invention is to make up for the shortage of bait technology in the existing abalone breeding process, and to provide a general-purpose high-efficiency puffed compound feed for young abalone. The feed is aimed at the characteristics of abalone’s seedling preservation period. It is greatly improved, and the growth-promoting effect of crony is brought into full play at the same time. The feed has comprehensive nutrition and a balanced combination of various ingredients, which is conducive to the balanced digestion and absorption of abalone, fast growth and high feed conversion rate.

In order to achieve the above object, the technical scheme that the present invention takes is:

A general-purpose high-efficiency puffed compound feed for young abalone, which is composed of imported fish meal, brewer's yeast, soybean meal, wakame, flour, calcium dihydrogen phosphate, choline chloride, casein, and abalone premix.
