Embodiment 1
[0023] Crumble the raw materials through a 40-mesh sieve (60-mesh sieve is less than 20%), and weigh (in g) according to the following formula: fish meal 100, soybean meal 250, rapeseed meal 150, cotton meal 50, peanut powder 70, bran 130 , soybean oil 30, premix 30, zeolite powder 10, calcium dihydrogen phosphate 20, secondary powder 90, kelp powder 70. After mixing and stirring evenly, send it to the granulator, and carry out granulation at 75-85°C. The granules are dehydrated by cold air, air-dried, and the finished product is obtained after packaging.
Embodiment 2
[0025] Grind the raw materials through a 40-mesh sieve (60-mesh sieve is less than 20%), weigh according to the following formula (unit g): fish meal 100, soybean meal 230, rapeseed meal 160, cotton meal 70, peanut powder 60, bran 120 , 40 soybean oil, 30 premix, 10 zeolite powder, 20 calcium dihydrogen phosphate, 150 secondary powder, 10 kelp powder. After mixing and stirring evenly, send it to the granulator, and carry out granulation at 75-85°C. The granules are dehydrated by cold air, air-dried, and the finished product is obtained after packaging.
Embodiment 3
[0027] Grind the raw materials through a 40-mesh sieve (60-mesh sieve is less than 20%), weigh according to the following formula (unit g): fish meal 120, soybean meal 200, rapeseed meal 180, cotton meal 80, peanut powder 60, bran 100 , soybean oil 50, premix 30, zeolite powder 20, calcium dihydrogen phosphate 20, secondary powder 110, kelp powder 30. After mixing and stirring evenly, send it to the granulator, and carry out granulation at 75-85°C. The granules are dehydrated by cold air, air-dried, and the finished product is obtained after packaging.

Abstract
The invention relates to a formula of allogynogenetic crucian carp fry feed and a processing method thereof. The feed formula consists of fish meal, bean pulp, rapeseed meal, cottonseed meal, peanut meal, bran, soy-bean oil, premix, zeolite powder, monocalcium phosphate, sub-powder and kelp powder. The feed preparation method comprises the following steps of: smashing the raw materials and passing the smashed materials through a 40 mesh screen, wherein materials resided on a 60 mesh screen is less than 20 percent; weighing the raw materials according to the formula and uniformly blending and mixing; feeding the mixed material into a granulator for granulation to obtain pellet feed; and dewatering by cold air, drying in air and packaging to obtain the finished product. The feed of the invention has the advantages that: the nutrition is overall and balance; the preparation processing method is simple; taste attract is high; stability in water is high; and a feed use ratio and a nutrient conversion ratio can be effectively improved, the pollution of cultivation water body can be reduced, the growth and development of aquatic animals can be promoted, and the quality of the cultured product can be improved.
Description
technical field [0001] The invention relates to a feed formula and a processing method for aquatic animals, in particular to a feed formula for heterogeneous gibel crucian carp and a processing method thereof. Background technique [0002] The heterogeneous gibel carp is the offspring of the fish breeding experts from the Institute of Hydrobiology, Chinese Academy of Sciences, using the natural gynogenetic development of Founder gibel carp as the female parent and Xingguo red carp as the male parent gynogenetic offspring. It has the characteristics of high yield, strong stress resistance, high survival rate, etc., and the meat is delicious and nutritious. [0003] With the development of the breeding industry and the improvement of the technical level, the breeding mode, scale, breeding density and breeding concept of heterogeneous gibel carp are constantly changing. Large-scale artificial breeding also puts forward higher requirements for feeding compound feed, water ecolo...
