preparation example Construction

[0022] The preparation method of above-mentioned total flavonoids of psyllium is as follows:

[0023] 1) Pulverize the whole herb of plantain air-dried at room temperature, add ethanol solution for extraction, and filter;

[0024] 2) concentrating the filtrate under reduced pressure to no alcohol to obtain a concentrated solution;

[0025] 3) Extract the concentrated solution with petroleum ether, and take the water layer extract;

[0026] 4) Pass the water layer extract through the macroporous resin column, and adsorb the flavonoids therein on the resin;

[0027] 5) Rinse the resin with 2 to 4 times the column volume of distilled water, and discard the effluent;

[0028] 6) Rinse the resin column with ethanol, elute the flavonoids, and collect the eluate;

[0029] 7) Ethanol and water in the eluent are removed to obtain psyllium flavonoids.

[0030] Preferably, the mass-to-volume ratio of the whole herb Plantago to the extraction ethanol solution is 1:10-30.

[0031] Pre...

Abstract

The invention discloses a prawn feed, which contains fish meal, bean pulp, peanut bran, rape seed dreg, saccharomyces cerevisiae, flour, starch, corn oil, fish oil, K2HPO4 and plantain seed total flavonoids. The prawn feed can remarkably improve the survival rate, weight increment rate and stress resistance of the prawn at the same time of ensuring the growth of the prawn. The consumption of the fish meal is remarkably lower than that of the conventional prawn feed at current markets, so the cost of the feed is greatly reduced.

Description

technical field [0001] The invention relates to a prawn feed. Background technique [0002] my country is a big country in shrimp farming, and its development momentum has become increasingly rapid in recent years. In 2003 alone, the total output of cultured prawns in the country reached 780,000 tons, which created huge economic benefits for my country's export earnings. However, with the improvement of the degree of intensive farming, the disease is becoming more and more serious. Because the prawn feed obviously lacks biologically active substances, the prawn feed plays an accomplice role in the outbreak of the prawn disease, and even the key driver. In the current situation where shrimp diseases are rampant, water pollution is intensified, and the weather is bad and changeable, shrimp feed has posed a serious threat to the safety of farming. [0003] With the prohibition of antibiotics, more and more professionals are paying attention to the development and application ...
