Disease-resistant highly-effective expanded compound feed for trachinotus ovatus

Abstract

The invention relates to disease-resistant highly-effective expanded compound feed for trachinotus ovatus. The feed is made of raw materials in the following weight ratios: imported steam fish meal 13-40, imported straight fire fish meal 10-30, biological fish meal ABP600 5-8, soybean meal 5-10, fermented soybean meal 5-8, soya meal 2-4, cotton seed meal 3-5, rape seed meal 3-5, meat and bone meal 3-8, cuttlefish meal 2-5, strong flour 25-33, blood meal 1.0-3.0, soybean lecithin 1.0-3.0, harp seal oil 2.0-5.0, choline chloride (5 percent) 0.4-1.0, vitamin C-phosphate ester (35 percent) 0.1-0.3, calcium dihydrogen phosphate 0.5-1.5, compound vitamins 0.2-0.5, compound mineral salt 0.5-1.5, phagostimulant 0.1-0.3, micro-ecological preparation 0.1-0.3, Beta-1,3 glucan 0.1-0.3, A3Alpha peptidoglycan 0.03-0.08, phytase 0.01-0.04, and non-starch polysaccharase 0.04-0.08. Cultivation experiments prove that the compound feed can meet all the requirements on nutrition of trachinotus ovatus cultivation in mesh cages and ponds, the cultivated trachinotus ovatus grow rapidly, the feed conversion rate is high, the color of the feed is vivid, the feed coefficient is between 1.8-2.1, the cultivation benefit is remarkable, the vitality of the cultivated trachinotus ovatus is good, the survival rate thereof is 6.0-10.5 percent higher than the survival rate when feed of other brands is used, and the death rate during long-distance transportation is reduced by over 60 percent.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a disease-resistant and high-efficiency puffed compound feed for oval pomfret. Background technique [0002] my country is the number one aquaculture country in the world, and it is also the only country in the world where the aquaculture output exceeds the fishing output. Aquaculture occupies a very important position in the national economy. In recent years, my country's aquaculture industry has developed vigorously, especially the fourth wave of aquaculture represented by marine fish farming is in the ascendant. Oval pomfret (Trachinotus blochii), commonly known as golden pomfret or yellow pomfret, is widely cultivated in the southern coastal provinces of my country due to its advantages of rapid growth, delicious taste, and the ability to use artificial compound feed throughout the whole process. However, there are few international and domestic researches on extruded compoun...

AI Technical Summary

Problems solved by technology

However, at present, there are few international and domestic researches on puffed pomfret compound feeds, and the existing brand compound feeds in the market have high coefficients and are expensive, resulting in a substantial increase in breeding costs.

At the same time, due to the current insufficient research on the nutrition of Pomfret ovata, the nutrients in the feed are difficult to fully meet the growth and metabolic needs of Pompano ovata, resulting in a decline in the immune function and stress resistance of the fish, and a low breeding survival rate

The above reasons have seriously hindered the further development of pomfret aquaculture
