Problems solved by technology

[0002] T-2, AF, DON, and OTA are mycotoxins that widely exist in nature and are easy to contaminate crops, thereby affecting aquatic feeds that use crops as raw materials. They are common mycotoxins that are strong carcinogenic, teratogenic, and toxic in aquatic feeds. Low residue levels can pose a greater food safety risk

Embodiment 1

[0025] Embodiment 1 inducer is to the reduction of mycotoxin

[0026] 1. Mycotoxin-infected prawns to be tested

[0027] Litopenaeus vannamei (L. vannamei, 6.5±0.5g / tail) used in the experiment came from Zhanjiang Donghai Island Breeding Base. After being transported back to the laboratory, put it in a 150L plastic box filled with about 2 / 3 volume of seawater for 24 hours of oxygen exposure all day. The number of shrimps in each box is about 35. The temperature is controlled at about 25°C, pH7.47~7.64, and it is timed every morning. Remove the excreta at the bottom of the prawn breeding box and replace 1 / 3 of the seawater. Afterwards, feed the prawns at 9:30, 15:30 and 21:30 Beijing time respectively. The daily feeding amount is 5% of the body weight of the prawns, and the feeding amount three times a day is 20% of the total daily amount. , 30% and 50%, feeding for a week.

[0028]Three kinds of mycotoxin microcapsule poisonous baits were prepared respectively, and the dose...

Embodiment 2

[0047] The influence of embodiment 2 inducers on the growth characteristics of prawns

[0048] During the experiment of increasing doses of three mycotoxins, the remaining feed of prawns was collected every morning and dried. And measure the body weight of the prawns after each period of exposure ends and calculate feeding rate (FR), weight gain rate (WG), specific growth rate (SGR), and the calculation formula is as follows:

[0049] Feeding rate (FR, %W·d -1 )=100×F / d / [((W 0 +W i ) / 2]

[0050] Weight gain rate (WG, %)=[W i -W 0 ] / W 0

[0051] Specific growth rate (SGR, %)=100×[lnW i -lnW 0 ] / d

[0052] In the formula, F-total food intake, dry weight, g; d-days, days; W-test shrimp body weight, wet weight, g; W 0 -Initial body weight of the test prawns, wet weight, g; W i -The body weight of the prawns on the i-th day of the test, wet weight, g.

[0053] Survival rate investigation: In the 20-day incremental exposure test, the survival rate of the shrimp in the c...

Abstract

The invention belongs to the technical field of biological prevention and control. Studies find that quercetin, rutin or tea polyphenol can activate GSTs (glutathione S-transferase), UGT (uridine diphosphate glucuronyl transferase), SULT (sulfotransferase) or AANAT (Arylamine N-acetyltransferase) in the non-contaminated prawn intestinal tract, so that the biotransformation of II phase enzyme is promoted; the activity of the entogenous detoxifying enzyme in the contaminated prawn intestinal tract is induced by adding an inductive agent into prawn feed, so that the metabolism of the prawn vivotoxin is accelerated; the toxin residue is reduced or cleared away; the prawn food safety is ensured.

Description

technical field [0001] The invention relates to the technical field of biological control, and more specifically, relates to the application of antioxidants in reducing mycotoxin residues in animals. Background technique [0002] T-2, AF, DON, and OTA are mycotoxins that widely exist in nature and are easy to contaminate crops, thereby affecting aquatic feeds that use crops as raw materials. They are common mycotoxins that are strong carcinogenic, teratogenic, and toxic in aquatic feeds. Low residue levels can pose a greater food safety risk. It can be accumulated through large aquaculture chains such as prawns and tilapia, endangering aquatic animals and even accumulating in them, and then passed to humans and animals through the food chain, endangering the health of humans and animals. Therefore, it is urgent to control and eliminate mycotoxins in aquatic feed. [0003] Mycotoxins enter the organism for biotransformation, which is an important part of the body's disposal ...
