Composite feed for loaches bred in courtyard

Abstract

The invention relates to the technical field of aquaculture and particularly relates to a composite feed for loaches bred in a courtyard. The composite feed is prepared from the following raw materials in parts by weight: 8-12 parts of bean dregs, 10-12 parts of rice bran, 20-25 parts of sweet corn, 10-12 parts of wheat middling, 10-12 parts of flaxseed meal, 6-8 parts of luffa flowers, 3-4 parts of duck blood powder, 3-4 parts of tubificidae powder, 1-2 parts of cooked duck egg yolks, 2-3 parts of whey powder, 3-4 parts of coriander, 5-6 parts of azolla imbricate stem leaves, an appropriate quantity of table salt and 4-5 parts of a phagostimulant. An appropriate quantity of cooked duck egg yolks and duck blood powder as well as the raw materials such as luffa flowers and coriander are added in the composite feed, so that the nutritional component requirement for rapid growth and development of loaches can be met; the digestive absorption of the loaches is promoted, so that the growth of the loaches is accelerated, the weight of the loaches is gained remarkably and therefore the breeding benefit is enhanced effectively.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a compound feed for garden loach cultivation and a preparation method thereof. Background technique [0002] Loach is known as ginseng in the water. Its meat is delicious, nutritious, and also has medicinal effects. It is an important type of special aquaculture fish with good economic benefits. Therefore, the loach breeding industry is gradually developing. The artificial breeding methods of loach mainly include Pond farming, paddy field farming, garden farming, etc. In the process of loach farming, feeding management is the most important link, which directly affects the economic benefits of farmers. Most of the existing loach feeds have problems of high protein content and lack of trace elements. As a result, the growth of loach is hindered. In order to improve the breeding efficiency and ensure the normal growth and development of loach, it is necessary to change the feed...

[0002] Loach is known as ginseng in the water. Its meat is delicious, nutritious, and also has medicinal effects. It is an important type of special aquaculture fish with good economic benefits. Therefore, the loach breeding industry is gradually developing. The artificial breeding methods of loach mainly include Pond farming, paddy field farming, garden farming, etc. In the process of loach farming, feeding management is the most important link, which directly affects the economic benefits of farmers. Most of the existing loach feeds have problems of high protein content and lack of trace elements. As a result, the growth of loach is hindered. In order to improve the breeding efficiency and ensure the normal growth and development of loach, it is necessary to change the feed structure and prepare feed with reasonable and balanced nutrition.
