Puffed compound feed for improving growth, feeding and survival of adult fishes in pompano

Abstract

The invention relates to a puffed compound feed for improving the growth, feeding and survival of adult fishes in pompano. The feed comprises the following components in parts by weight: Peruvian-Taiwan-grade fish meal, Antarctic krill meal, Vietnamese 65% seawater fish meal, Indian 65% seawater fish meal, pet-grade chicken meal, pig blood ball protein powder, cottonseed protein, corn protein powder, soybean meal, tapioca starch, high-gluten flour, enzymolyzed squid paste, enzymolyzed fish slurry, squid oil, refined fish oil, soybean phospholipid oil, calcium dihydrogen phosphate, vitamin premix, mineral salt premix, choline chloride, astaxanthin, a DMPT attractant, an antioxidant and a mildew inhibitor. The feed has the advantages of good stability, fast heart penetration time and convenience for digestion and absorption of animals after feeding. The compound feed has good attractivity and palatability, and can effectively improve the feeding amount of the pompano, thereby improving the growth speed of animals. The compound feed can improve the survival rate of animals.

Description

technical field [0001] The invention relates to an extruded compound feed, in particular to an extruded compound feed that improves the growth, feeding and survival of adult fish in oval pomfret. Background technique [0002] Oval pomfret, Latin name: Trachinotus ovatus, commonly known as golden pomfret, pomfret, red three-yellow pomfret, belonging to Perciformes, Carangidae, pomfret genus Trachinotu, belonging to warm water fish, widely distributed in The Pacific Ocean, Atlantic Ocean and Indian Ocean are also widely distributed in the South my country Sea and East China Sea. [0003] The oval pomfret has a flat side, oval shape, fast growth rate, strong disease resistance, tender meat, delicious flavor and high nutritional value. The output is as high as 150,000 tons. In its natural state, the oval pomfret is an omnivorous and carnivorous fish. [0004] Before 2010, the oval pomfret mainly ate rough and fresh fish, but because of the existence of frozen fish: difficult t...

AI Technical Summary

Problems solved by technology

[0004] Before 2010, pomfrets mainly ate coarse and chilled miscellaneous fish. However, due to the existence of chilled miscellaneous fish, it is difficult to store, easily spoiled, breeds bacteria, water pollution leads to eutrophication of aquaculture water, and seriously affects wild fish resources. , increased labor costs, and unbalanced nutrition. Since 2010, pompano ovata has been gradually domesticated and can eat artificial compound feed. The feed demand in the trevally market is as high as more than 200,000 tons

[0005] However, a large number of experimental data and breeding data show that the following difficulties have not been overcome for the ovate pomfret feeding on artificial compound feed: (1). Fish with lower food intake than fresh chilled trash fish

(2) There are differences in nutrition between artificial compound feed and fresh chilled miscellaneous fish, resulting in the growth rate of fish feeding on feed is not as good as that of fish eating fresh chilled miscellaneous fish

(3) Fish that eat artificial compound feed are more likely to have some liver and intestinal digestion problems than fish that eat fresh chilled miscellaneous fish, causing animals to have enteritis diseases and eventually cause death
