Embodiment 1

[0024] When preparing the feed of this embodiment, firstly, various protein sources are pulverized into powders with a pulverizer; then, sieve through a 40-mesh sieve to remove protein source particles that are not pulverized. Then according to fish meal 16%, animal and plant composite protein 44%, fat 8%, tapioca starch 7%, soybean lecithin 0.2%, choline chloride 0.2%, vitamin premix 1%, mineral premix 1%, Ethoxyquinoline 0.02%, calcium dihydrogen phosphate 0.2%, betaine 0.2%, microcrystalline cellulose 21.58%, L-lysine 0.2%, L-methionine 0.2%, L-arginine 0.2% by mass Proportioning Weigh each component, and fully mix each component in a feed mixer. Finally, use a feed pellet extruder to pellet the mixed feed.

[0025] Present embodiment compares the effect of existing feed as shown in the following table:

Embodiment 2

[0028] When preparing the feed of this embodiment, firstly, various protein sources are pulverized into powders with a pulverizer; then, sieve through a 40-mesh sieve to remove protein source particles that are not pulverized. Then according to fish meal 18%, animal and plant composite protein 46%, fat 10%, tapioca starch 9%, soybean lecithin 0.6%, choline chloride 0.6%, vitamin premix 1.5%, mineral premix 1.5%, Ethoxyquinoline 0.03%, calcium dihydrogen phosphate 0.3%, betaine 0.3%, microcrystalline cellulose 11.27%, L-lysine 0.3%, L-methionine 0.3%, L-arginine 0.3% by mass Proportioning Weigh each component, and fully mix each component in a feed mixer. Finally, use a feed pellet extruder to pellet the mixed feed.

[0029] Present embodiment compares the effect of existing feed as shown in the following table:

Embodiment 3

[0032] When preparing the feed of this embodiment, firstly, various protein sources are pulverized into powders with a pulverizer; then, sieve through a 40-mesh sieve to remove protein source particles that are not pulverized. Then according to fish meal 20%, animal and plant composite protein 48%, fat 12%, tapioca starch 11%, soybean lecithin 1%, choline chloride 1%, vitamin premix 2%, mineral premix 2%, Ethoxyquinoline 0.04%, calcium dihydrogen phosphate 0.4%, betaine 0.4%, microcrystalline cellulose 0.66%, L-lysine 0.5%, L-methionine 0.5%, L-arginine 0.5% by mass Proportioning Weigh each component, and fully mix each component in a feed mixer. Finally, use a feed pellet extruder to pellet the mixed feed.

Abstract

The invention discloses trachinotus ovatus juvenile compound feed with animal-vegetable compound protein replacing fish meal and a preparation method of the trachinotus ovatus juvenile compound feed,and relates to the field of component improvement of fish feed. The feed is prepared from fish meal, animal-vegetable compound protein, fat, tapioca starch, soybean lecithin, choline chloride, vitaminpremix, mineral premix, ethoxyquin, monocalcium phosphate, betaine, microcrystalline cellulose, L-lysine, L-methionine and L-arginine; the components are compounded in certain proportion according tothe principle of amino acid balance to obtain a protein source. Compared with existing trachinotus ovatus juvenile compound feed, the addition amount of fish meal in the feed formula disclosed by theinvention is reduced by 40%, and the feed cost is reduced by 11.6%; meanwhile, the weight gain rate of the trachinotus ovatus juvenile is increased by 16.7%, and the feed coefficient is reduced by 13.04%.

Description

technical field [0001] The invention relates to the field of fish feeding feed, in particular to a compound feed which uses animal and plant compound protein instead of fish meal to feed juvenile pomfret pomfret, and a preparation method of the feed. technical background [0002] Oval pomfret, commonly known as golden pomfret and yellow pomfret, has the characteristics of fast growth, delicious meat, simple diet, strong stress resistance and high survival rate, and has important economic value. At present, the annual aquaculture output of oval pomfret is more than 120,000 tons, and it is one of the main cultured marine fish species in the southern coastal areas of my country. In actual production, a large amount of fishmeal needs to be added to the compound feed of pomfret pomfret, which makes the compound feed expensive and restricts the development of its breeding industry. [0003] At present, although a lot of research has been carried out on the substitution of fish me...
