Problems solved by technology

Nowadays, there are many varieties of fish feeds, and the quality varies. Many fish feeds are unbalanced in nutrition. After long-term consumption of fish, it will lead to low immunity, susceptibility to disease, and dull body color. Some fish feeds are poor in stability and easy to pollute water quality. underutilized

preparation example Construction

[0032] A method for preparing the above-mentioned fish feed comprises mixing energy feed, protein feed, food-promoting plants, vitamins, minerals, carriers and binders.

[0033] Preferably, before mixing, energy feed, protein feed, food-promoting plants, vitamins, minerals, carriers and binders are pulverized and passed through a 30-60 mesh sieve to obtain under-sieve materials. Make the mixed raw materials more delicate.

[0034] Preferably, the puffing is extruded and puffed at a temperature of 120-135°C and a pressure of 1.5-2.5 MPa. Under the high-temperature treatment conditions, on the one hand, the starch is gelatinized, and the fat is stabilized and undegraded; and soften the fiber structure and cell wall, so that the utilization rate of various nutrients is improved. At the same time, the expansion process also destroys harmful substances such as myrosinase in rapeseed cake, trypsin in soybean meal and other harmful substances and growth inhibitory factors, thereby im...

Embodiment 1

[0038] A kind of fish feed with a particle size of 0.8 mm, which consists of 23.8 parts by weight of energy feed; 41 parts by weight of protein feed; 1.6 parts by weight of vitamins; 1.3 parts by weight of minerals; 2.4 parts by weight of food-promoting plants; 4.9 parts by weight 5.6 parts by weight of the carrier and 5.6 parts by weight of the binder are pulverized, mixed with the under-sieved material obtained after passing through a 30-60 mesh sieve, extruded and puffed at a temperature of 128°C and a pressure of 1.8MPa, and dried at 62°C 8h, granulation.

[0039] Among them, the energy feed includes 21 parts by weight of corn, 0.8 parts by weight of lard, and 2 parts by weight of soybean oil; the protein feed includes 27 parts by weight of soybean meal, 8 parts by weight of rapeseed cake, 2.5 parts of earthworm meal, and 3.5 parts by weight portion of tea leaves; the food-promoting plant is Houttuynia cordata. Minerals include chelated calcium, chelated phosphorus, chela...

Embodiment 2

[0041] A kind of fish feed that particle diameter is 3.5mm, and it is by the energy feed of 23 parts by weight; The protein feed of 38.2 parts by weight; The vitamin of 1.3 parts by weight; The mineral matter of 1.7 parts by weight; Parts by weight of the carrier and 5.7 parts by weight of the binder are pulverized, and the under-sieve material obtained after passing through a 60-mesh sieve is mixed, extruded and puffed at a temperature of 130°C and a pressure of 1.8MPa, and dried at 71°C for 6 hours , granulation.

[0042] Among them, the energy feed includes 20 parts by weight of corn, 0.7 parts by weight of lard, and 2.3 parts by weight of soybean oil; the protein feed includes 23 parts by weight of fermented soybean meal, 7 parts by weight of fermented rapeseed cake, and 3.7 parts by weight of earthworm powder , and 4.5 parts by weight of fermented tea leaves; the food-promoting plant is Houttuynia cordata. Minerals include chelated calcium, chelated phosphorus, chelated ...

Abstract

The invention relates to fish feed and a preparation method thereof, and relates to the field of feed processing. The fish feed is prepared from 15-30 parts by weight of energy feed, 25-50 parts by weight of protein feed, 1-2 parts by weight of vitamins, 1-2 parts by weight of minerals, 2-3 parts by weight of feeding attractive plants, 4-5 parts by weight of a carrier, and 5-6 parts by weight of an adhesive through mixing, puffing and pelletizing. The fish feed is balanced in nutrition, the growth speed of fishes can be increased, the immunity of the fishes can be improved, and the fishes can be prevented from diseases. In addition, the invention further relates to a method for preparing the fish feed. The method comprises the following steps: mixing, puffing and pelletizing the energy feed, the protein feed, the vitamins, the feeding attractive plants, the minerals, the carrier and the adhesive. The preparation process is free of pollutant and is clean and environmentally friendly.

Description

technical field [0001] The invention relates to the field of feed processing, and in particular to a fish feed and a preparation method thereof. Background technique [0002] With the continuous improvement of pond fish farming and rice paddy fish farming technology, the high-input, high-yield intensive pond farming technology is becoming more and more refined. Now the market demand is shifting from more fish to higher quality fish. In the process of pond intensive farming, the use of feed not only directly affects the economic benefits of fish farmers, but also affects the quality of farmed fish. [0003] Fish feed, as the name suggests, is feed for fish. The main components of fish feed: the main components protein, fat, vitamins and minerals. The nutritional content of the feed can not only affect the normal growth of fish, but also affect the immune and disease resistance of fish. The purpose of feeding fish is to provide the necessary nutritional requirements for th...
