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): linseed gum 25, ginger 7, soybean lecithin 20, diatomaceous earth 75, rapeseed meal 350, linseed oil 35, secondary powder 300, pandan leaf juice 22, Fish oil 30, lotus root powder 85;

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

[0021] (1) After mixing the rapeseed meal, ginger, sub-flour powder, and lotus root powder, 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 soybean lecithin in a container, and continuously feed water vapor for hydrothermal treatment for 200 minutes to obtain a mixed material. Stir well and set aside;

[0023] (3) Put the mixed material...

Abstract

The invention discloses high-food-luring-property tilapia mossambica feed with fish oil being partially replaced by linseed oil. The high-food-luring-property tilapia mossambica feed is prepared from, by weight, 23-27 parts of linseed gum, 5-8 parts of fresh ginger, 18-22 parts of soyabean lecithin, 70-80 parts of diatomite, 340-360 parts of rapeseed dregs, 34-36 parts of linseed oil, 290-310 parts of wheat middlings, 20-24 parts of pandan leaf juice, 28-32 parts of fish oil and 75-95 parts of lotus root starch. According to the tilapia mossambica feed, the rapeseed dregs and the wheat middlings are used as the main raw materials, the added soyabean lecithin can reduce dust in feed processing, the bonding effect is achieved, and the abrasion resistance and water resistance of feed particles are improved; meanwhile, the feed has certain palatability and food luring property to tilapia mossambica, and feed intake is increased; the added pandan leaf juice contains a large number of vitamins, hence, when the pandan leaf juice coats the outer surfaces of the particles in an outer coating mode, the effectiveness of the ingredients can be guaranteed, and the feed is novel tilapia mossambica feed which is high in nutritive value and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a highly attractive 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,...
