Embodiment 1

[0018] Taking the production of 2.0 mm grain size of the pachybranchus as an example, fish meal 30 kg; flour 20 kg; corn gluten meal 10 kg; soybean meal 16 kg; rapeseed meal 11 kg; soybean oil 2 kg; brewer's yeast 5.7 kg kg; choline chloride 0.5 kg; calcium dihydrogen phosphate 2 kg; laminarin 0.2 kg; spirulina powder 0.8 kg; multivitamins 0.3 kg; multiminerals 1.5kg.

[0019] Mix fish meal, corn gluten meal, soybean meal, rapeseed meal, brewer's yeast, choline chloride, and calcium dihydrogen phosphate thoroughly and then pulverize them. More than 98% of them pass through a 40-mesh sieve, and add flour, laminarin, and multivitamins in proportion , compound mineral salts, spirulina powder and soybean oil, and mix them evenly again; use a ring die granulator to extrude and granulate the mixture into 2.0 mm buoyant pellet feed.

Embodiment 2

[0021] Taking the production of the 3.0 mm grain size of the semi-spined pachyrhiza compound feed as an example, 26 kg of fish meal; 21 kg of flour; 12.5 kg of corn gluten meal; 14 kg of soybean meal; 14 kg of rapeseed meal; 3 kg of soybean oil; 4.6 kg of brewer's yeast kg; choline chloride 0.4 kg; calcium dihydrogen phosphate 2 kg; laminarin 0.2 kg; spirulina powder 0.6 kg; multivitamins 0.4 kg; multiminerals 1.3 kg.

[0022] Mix fish meal, corn gluten meal, soybean meal, rapeseed meal, brewer's yeast, choline chloride, calcium dihydrogen phosphate thoroughly and evenly, then pulverize, and more than 98% pass through a 40-mesh sieve, and add flour, laminarin, compound The vitamins, compound mineral salts, spirulina powder and soybean oil were mixed evenly again; the mixture was extruded and granulated into 3.0 mm floating pellet feed using a ring die granulator.

Embodiment 3

[0024] Taking the production of the compound feed for the 4.0 mm thick lipped fish as an example, fish meal 22 kg; flour 22 kg; corn gluten meal 14.6 kg; soybean meal 13 kg; rapeseed meal 16 kg; soybean oil 4 kg; brewer's yeast 4 kg kg; choline chloride 0.3 kg; calcium dihydrogen phosphate 1.8 kg; laminarin 0.1 kg; spirulina powder 0.5 kg. Multivitamin 0.5 kg; multimineral 1.2 kg.

[0025] Mix fish meal, corn gluten meal, soybean meal, rapeseed meal, brewer's yeast, choline chloride, calcium dihydrogen phosphate thoroughly and evenly, then pulverize, and more than 98% pass through a 40-mesh sieve, and add flour, laminarin, compound Vitamins, compound mineral salts, spirulina powder and soybean oil were mixed evenly again; the mixture was extruded and granulated into 4.0 mm floating pellet feed using a ring die granulator.

Abstract

The invention provides a compound acrossocheilus hemispinus feed and a preparation method thereof. The feed comprises the following components in parts by weight: 20 to 32 parts of fish meal; 20 to 23parts of flour; 8 to 15 parts of corn protein powder; 12 to 18 parts of soybean meal; 10 to 16 parts of rapeseed meal; 2 to 5 parts of soybean oil; 4 to 6 parts of brewer's yeast; 0.2 to 0.5 part ofcomposite vitamin; 1.0 to 1.5 parts of composite minerals; 0.2 to 0.5 part of choline chloride; 1 to 2 parts of calcium dihydrogen phosphate; 0.1 to 0.2 part of laminarin; and 0.5 to 0.8 part of spirulina powder. The compound acrossocheilus hemispinus feed disclosed by the invention can solve the problem existing in the present artificial culturing process of acrossocheilus hemispinus that: growthspeed is slow; culturing cost is high; and nutrition stress diseases easily occur and frequently occur and fish physique declines due to the fact that substitute feed nutrient components do not meetthe requirements of the acrossocheilus hemispinus.

Description

technical field [0001] The invention belongs to the field of aquatic feeds, and in particular relates to a compound feed for the pachyrhiza and a preparation method thereof. Background technique [0002] In recent years, research and development work on freshwater indigenous economic fish has been highly regarded. Due to the construction of water conservancy projects and the development of mountainous areas, the traditional habitat and living environment of indigenous fish have been changed, and illegal fishing and overfishing, such as illegal fishing and overfishing, stimulated by short-term economic interests such as strong market demand, have brought serious damage to the wild resources of indigenous fish. The devastating damage; coupled with the deterioration of their living environment due to sand mining in the river and various pollution sources, eventually led to a sharp decline in the wild germplasm resources of these indigenous fish, and some species even have the r...
