First, the mold removal agent only has no standard 1. There is no standard for the fungicide. The measurement of the adsorption rate of mycotoxins has always been a world problem. It is as difficult as the detection of energy in feed. There are also many unavoidable questions, such as the in vitro adsorption and in vivo adsorption are comparable? Adsorption nutrition? So far, no formal mycotoxin adsorption standards have been established in the EU, the US and China, nor have the fungicides been officially included in the list of additives. 2, the fungicide is still in the concept stage: the industry has recognized the harm of mycotoxins, also know that some additive materials have a certain adsorption rate, but the actual adsorption rate is still very problematic, countries are inconclusive, no standard . A lot of so-called adsorption rates, most of which are the words of the manufacturer, have the suspicion of exaggerating the efficacy of their products. 3, the role of the fungicide is limited, basically in the raw material check: regular additives can play a certain role in adsorption. However, if the feed is mildly moldy, it is impossible to solve the problem with the fungicide, especially non-polar toxins. Ultimately, the control of feed ingredients is the fundamental and key to controlling mycotoxins. Second, the market lotion is very confusing and counterfeit and a lot of Market sales are mainly based on foreign brands. The early understanding of mycotoxins benefited from the guidance and promotion of foreign brands, which made many foreign brands deeply rooted in the hearts of the people. Now there are almost all countries in the market, the price is from 10 yuan to 100 yuan per kilogram, and even a few dollars, so that the vast majority of consumers can't figure out what to do. There are many "counterfeit" products. Products such as "Moldy XX" are available in a variety of markets, with different prices, but 90% are counterfeit products, printed on the same packaging, but produced by illegal traders across the country and sold throughout the country. Another phenomenon is that many companies have applied for the batch number of a foreign product (external feeding standard, valid for 5 years), and put in one or two tons of goods. Then use this batch number to produce it yourself, the quality is difficult to be guaranteed. What's more, directly targeting foreign brands is catching up with the wind, approving the quality standards of the document number, etc., directly printing foreign-style packaging bags, and loading a few pounds of bentonite for sale. Third, the secret of foreign feeding quasi- The import of foreign feed and additives should be preceded by an approval document number. This is the “external feeding quasi-wordâ€. However, after the handling, as for whether to import or import, the Ministry of Agriculture is not known. The Customs only manages the goods of the import and export customs, and the imported products sold in the market cannot be managed. This has formed a "drilling space" industry, to do a real "external feeding quasi-word", and then impersonate their own production, thus eliminating the need for a "production license", "product approval number" and so on, basically Avoid spot checks and assume quality responsibility. Why are there so many fake and shoddy products? The subjective reason is that our consumers cannot correctly understand mycotoxins and adsorbents; the objective reason is that the mycotoxins themselves are difficult to detect comprehensively and accurately, and the harm of mycotoxins is difficult to quantify and clarify. The adsorption effect of the mycotoxin adsorbent is more difficult to detect and quantify, and we are almost 100% dependent on the feeling. Five, the majority of breeding users in the misunderstanding of the effect of The only way for pig breeders to treat mycotoxins is "small pig swollen umbilical cord". As long as the piglet swollen umbilical cord is known to be a mycotoxin poisoning, use a mildew remover. The understanding of the anti-mold agent is simply that "if the pig is used, the piglet does not swollen the umbilical, it is a good mold remover." In fact, this view is not comprehensive. The piglet umbilical cord is caused by zeara zein toxin, and the zeara zein toxin is difficult to adsorb. It is recognized that the best fungicide can only reach about 60%. Adsorption efficiency. The so-called propaganda rate of 90% is difficult to confirm. However, the farm only looks at the apparent effect, as long as it does not swollen the umbilical is a good anti-mold agent. Caused by many manufacturers speculation, there are XXX brands only sell "yeast cell wall", simply solve the problem of swollen umbilical; more than a lot of add antidote, cure the swollen umbilical. In fact, it is only effective for F2 toxins, and it has no effect on the more serious aflatoxins. To this end, we surveyed a number of users of several foreign brand anti-mold agents using a few ten thousandths of the use, all of which reflected that "the pig swollen umbilical cord is gone, but there are still many diseases, no reduction", which basically reflects Its adsorption efficiency to aflatoxins and the like is very poor. It is believed that foreign brands have good quality and high credibility. This is giving the counterfeiters the opportunity to take the opportunity to pretend or fabricate a large number of foreign brands that are harmful to consumers. In fact, with the development of China's manufacturing industry in recent years, several major adsorbent materials in China have been fully manufactured and the quality is very good. Many foreign manufacturers buy Chinese materials to produce. Sixth, the principle of adsorption of Materials that have been shown to have high efficiency to adsorb mycotoxins are now derived from three sources: montmorillonite, modified aluminosilicate crystals, yeast cell wall extracts. The former two are lower in cost and the latter are more expensive. 1. Montmorillonite: It has two crystal layer structures of 2:1, one octahedron and two tetrahedrons, and the thickness is 10 angstroms. There is no hydrogen bond between the layers, so the gap between the layers is wide, and the mycotoxin molecules are easy. It is adsorbed into the interstitial space and has a large surface area of ​​700 m2 per gram (this is the clearest surface area seen in nature), so montmorillonite is also called the king of adsorption. It is one of the best adsorbents for aflatoxins. Montmorillonite mainly adsorbs mycotoxins through electrostatic imbalance between internal structural layers. Clay has strong binding ability to small water molecules and certain mycotoxins, such as aflatoxin, ochratoxin and the like. However, the dry montmorillonite structure layer has a pitch of 0.25-0.7 nm and a water content of 1 nm, and it is difficult to adsorb some mycotoxins having a large volume, such as F2, T2, fumagillin and the like. At present, there is a so-called "nano" grade adsorption grade in the market. In fact, it is not the nanometer-scale fineness of the adsorbent material, but the nanoscale crystal layer structure of the silicate crystal. 2, modified aluminosilicate crystal: is a smectite and other aluminosilicate, using some organic matter for this property, in principle, the interlayer column of aluminosilicate such as montmorillonite is considered to expand, thus making the interlayer The space is expanded by 2-10 times to adsorb the macromolecular mycotoxin. However, due to its nature, the adsorption efficiency is difficult to ensure. 3. Yeast cell wall extract: The main component of the yeast cell wall is: divided into 3 layers: the middle layer is a glycoprotein layer, and the inner and outer layers are respectively a dextran layer and a mannan layer. Glucan (about 30% to 34% of the dry weight of the cell wall) and mannan [about 30% of the dry weight of the cell wall, the actual use of mannooligosaccharides in the production, is the enzymatic hydrolysis of mannan completely from α-( The 1,6)-glycosidically linked backbone is cleaved to create several oligosaccharide side chains. Among them, mannooligosaccharides and mannans have the function of adsorbing mycotoxins, especially for the adsorption of fungi toxins such as F2. Since mycotoxins are high in the feed and widely available, and all the fungicides are not 100% adsorbed, any mycotoxin adsorbent can only reduce the risk of mycotoxins in different degrees, but it cannot relieve 100% of mycotoxins. Loss. The toxicity and toxicity caused by mycotoxins in animals should be ruled out. The enzymatic hydrolysis of B-glucan added in the mold removal has the function of detoxification through the immune system, so this is also a unique feature of the mold removal (two-way removal). It refers to the harm of mycotoxins in two different directions by in vitro adsorption and detoxification in vivo. 4, the molecular size of several major mycotoxins (unit: nm) H: approximate size of molecules at possible adsorption sites; L: the approximate size of the molecule after rotating 90 degrees from the H position. Seven, the purchase of some of the appearance of the identification 1. If it is a mineral adsorbent, the particle size requirement is particularly fine, at least 28um or less. If it is very thick, it can be judged as false. 2. High-purity regular adsorbent, dry and not dense. If it is not much but heavy in the bag, it can be judged to be false. 3, can be used for water analysis, the mineral mold remover is suspended after stirring, will not produce large sinking particles; and the addition of the yeast cell wall extract of the mold remover, there are non-mineral powder separated, floating. Eight, using the three simple identification of the Identification 1: Whether the incidence rate is reduced (at least for more than 2 months) (measuring the adsorption efficiency of mycotoxins represented by aflatoxin) Identification 2: Whether the appetite and feed intake of the livestock increased, and whether the egg weight of the egg increased in the first month (measured as the adsorption efficiency of the mycotoxin represented by T2 and vomiting toxin) Identification 3: Whether the wigs of livestock are alleviated, whether the eggs, poultry and eggs are clean (measuring the adsorption efficiency of mycotoxins represented by F2 toxins) Nine, on the adsorption effect of mycotoxins observation Mainly through three aspects to observe the 1. Immunity: The biggest hazard of mycotoxins is the immune damage caused by aflatoxins, which seriously damages the animal's immune system and liver, causing the disease resistance of animals to decrease and the vaccine titer to decrease and the antibodies to be short and uneven. . Anatomical analysis: To observe the thymus, spleen and other immune organs of the size and health of the observed damage of the liver Biochemical detection: comparative analysis of antibody height, retention time, uniformity; immunoglobulin levels, etc. Apparent phenomenon: Long-term comparison of incidence rate and death rate; poultry special observation of fatty liver and egg weight changes, livestock focus on observing estrus, mastitis and so on. Simple identification: Eggs and birds are the simplest. Observe the changes of fatty liver and egg weight. Generally, the use of mildew remover increases the egg weight in the first month and then returns to normal. The breeding birds track fertilization rate, health rate and survival rate of chicks. 2, feeding and weight: T2, vomiting toxins, etc. can seriously cause the animal to refuse to eat, weight loss. Pigs can cause animals to not eat, slow weight gain, delay in slaughtering and high meat-to-meat ratio, while poultry are generally thinner and have a higher rate of death. Simple identification: After observing the use of mycotoxin adsorbent, whether the feed intake of livestock is significantly increased, the weight gain is accelerated, or the weight of the poultry is restored, and the death of the dead is reduced. Otherwise, the mycotoxin content is high, and the amount of the mold remover is not enough. Or there is a problem with the quality of the remover used. 3, reproduction: Because F2 toxin can cause wigs in livestock, young animals swollen umbilical, so that everyone can recognize the harm of mycotoxins from the surface. However, other mycotoxins such as F2 and aflatoxin can cause reproductive defects more deeply. The performance of livestock is: bad estrus, stillbirth, miscarriage, dystocia, low birth rate, weak babies, low survival rate, shortened age of dams, mastitis. The main manifestations of poultry are: short or no peak at the peak, low fertilization rate of the poultry, salpingitis, dirty eggs, bloody feces, and anal fistula. Simple identification: look at the wig, swollen umbilical, look at the quality of the egg, Ten, the grade of mycotoxin adsorbent Not counting counterfeit informal products, the mold toxin adsorbent produced by regular manufacturers is divided into three grades: 1- Low grade is a single mineral adsorbent, which can only adsorb Aspergillus flavus and ochratoxin. Only the “identification one†is consistent, and it is difficult to prove other effects. The average market price of this mold remover is about 10 yuan per catty. But the basics below 10 yuan are informal products, the lower one. 2-Medium-grade, one is a composite adsorbent, which combines a combination of enzyme preparations on the basis of a single mineral adsorbent, which can adsorb aflatoxin and reduce "swollen umbilical cord", but can not confirm "identification two ". The other is a single yeast cell wall extract that is expensive to sell and is typically used in very small parts. The adsorption of aflatoxin is very inefficient, and the adsorption of F2 toxin is very good, and it is effective to solve the "swollen umbilical". This kind of product looks like high-end, and it just coincides with the user's mentality of "not swollen umbilical is good". The effect is very uncertain, and it can confirm the "identification three", but "identification one and identification two" cannot be confirmed. 3- high-grade, belonging to the fourth generation of mycotoxin adsorbents. It is required to comprehensively renovate and cooperate with the three major materials, and it is necessary to make a true "three-dimensional broad-spectrum adsorption" and at the same time have a certain toxin removal effect in the body. Eleven, mycotoxin adsorption efficiency (reference) [XX good] adsorption rate of major mycotoxins (calculated) To measure the quality of the mycotoxin adsorbent can not only refer to the adsorption rate given by each company, because even the best adsorbent does not have 100% adsorption, especially F2 toxin, the adsorption rate given by each company can only be done. reference. More importantly, it can solve the immunosuppression and reproductive damage caused by the mycotoxin of the nettle, which is a more thorough means to solve the damage of mycotoxins.
