Problems solved by technology

Tilapia is an omnivorous fish, and its growth, development, and metabolic processes require a large amount of n-3 unsaturated fatty acids, and fish oil is rich in n-3 fatty acids such as docosahexaenoic acid and eicosapentaenoic acid. Unsaturated fatty acids are widely used as a fat source in traditional feed, but the price of fish oil is too high due to the shortage of resources, which increases the cost of feed

Embodiment Construction

[0017] specific implementation plan

[0018] The present invention will be described in further detail below in conjunction with the following specific embodiments:

[0019] Weigh the following raw materials in parts by weight (kg): fish oil 32, linseed oil 41, linseed gum 20, eucalyptus oil 2, tapioca starch 50, cottonseed meal 320, diatomaceous earth 70, rapeseed meal 340, corn Germ oil 18, bean curd residue 140;

[0020] The concrete steps of the preparation of described tilapia feed are as follows:

[0021] (1) After mixing the rapeseed meal, bean curd residue and cottonseed meal, place them in a pulverizer to pulverize the materials and mix them uniformly by a small amount of multiple times;

[0022] (2) Put the powdery material obtained in step 1, linseed gum, and tapioca starch in a container, and continuously feed water vapor for hydrothermal treatment for 170 minutes to obtain a mixed material, and mix diatomaceous earth and linseed oil at 40 ° C. Stir well and set...

Abstract

The invention discloses high-nutrient tilapia mossambica feed with fish oil being partially replaced by linseed oil. The high-nutrient tilapia mossambica feed is prepared from, by weight, 30-34 parts of fish oil, 38-44 parts of linseed oil, 18-22 parts of linseed gum, 1-3 parts of eucalyptus oil, 40-60 parts of tapioca starch, 300-340 parts of cottonseed meal, 68-72 parts of diatomite, 320-360 parts of rapeseed dregs, 15-20 parts of maize germ oil and 120-160 parts of soybean curb residues. The tilapia mossambica feed can meet the growth needs of tilapia mossambica through scientific matching, and the added rapeseed dregs, the cottonseed meal and the soybean curb residues provide sufficient protein for the tilapia mossambica; the fish oil, the linseed oil and the maize germ oil are used as fat sources; meanwhile, the tapioca starch is added, so that the feed bonding function is achieved, the tapioca starch is also an absorbable nutritional ingredient, metabolism defection of the tilapia mossambica can be reduced, nutritive losses are reduced, breeding pollution is lightened, and therefore a guarantee is provided for healthy development of the tilapia mossambica.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a high-nutrition tilapia feed formula in which linseed oil partially replaces fish oil and a preparation method thereof. Background technique [0002] Tilapia is the main farmed fish in my country and is deeply loved by consumers. Tilapia is an omnivorous fish, and its growth, development, and metabolic processes require a large amount of n-3 unsaturated fatty acids, and fish oil is rich in n-3 fatty acids such as docosahexaenoic acid and eicosapentaenoic acid. Unsaturated fatty acids are widely used as a fat source in traditional feed, but the price of fish oil is too high due to the shortage of resources, which increases the cost of feed. Therefore, the present inventor has designed a kind of tilapia feed that greatly reduces the consumption of fish oil, wherein used fish oil and linseed oil as the fat source of tilapia, linseed oil contains a large amount of α-linolenic acid, an...
