Heating method is divided into dry heat method and wet heat method. The dry heat method includes baking, microwave radiation, infrared radiation, and the like; the wet heat method includes cooking, hot press, extrusion, and the like. High heating method is high, simple and easy, no residual problems, the cost is also low, but it is only suitable for thermal unstable anti-nutrient factors, thermally stable anti-nutrient factors such as phytic acid, saponin, cyanide , Oligosaccharides and the like are poor. During heating, insufficient heating cannot completely eliminate anti-nutrient factors, while heating will destroy arginine, lysine and certain sulfur amino acids in production.

(2) Water soaking method can be soluble in water, which can be removed using this nature. For example, soaking with water, the soluble NSP can be removed. However, after water soaked, it must be dried and the cost is relatively high, and it is inconvenient in production.

The machining method includes pulverizing, peeling, etc. Most anti-nutrient factors are concentrated in a particular location of plants, and they can eliminate their anti-nutrients by machining. For example, sorghum, broad beans, remove the outer skin to remove most of the tannins in the seeds.

The method of treating the acid-base treatment, ammonia treatment, and the treatment of special substances, and the like. These methods can remove part of the anti-nutrient factor in the feed. KV2 China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
Soak the cottonseed in the cottonseed in 2% lime water or 1% aqueous alkaline aqueous solution, then eluting with water, you can remove most Cottonseed alcohol. Studies have shown that using 5% urea and 20% water to treat soybean meal for 30 days, and urease activity is reduced by 90%. 10 mol / s slycids C and 0.5 mol / liter sulfate Copper were added to soy bean meal, and it was treated at 27 ¡ã C for 1 hour, which allowed for 1 hour of KTI, for 1 hour at 65 ¡ã C, which allowed more than 90% or more. KTI and BBI inactivation. The chemical method is used to save equipment and energy, but the disadvantage is that the residue of chemical substances, affecting feed, and pollutes the environment.

3. Biology Method (1) Enzyme preparation KV2 China feed industry information network – based on feed, service animal husbandry
With science and technology and biotechnology Constantly develop, more and more enzyme preparations are used in feed production, add enzyme preparations in feeds, on the one hand, inactivation of anti-nutrient factors in the feed; on the other hand, the utilization of the feed can be improved. The most widely used enzyme preparation in this stage is phytase. The study pointed out that the optimization conditions of the phytase alternating vegetable seed cake were at a temperature of 45 ¡ã C, pH 4.7, and the reaction time was 90 minutes, the enzyme concentration was 2.4%, under the above conditions, the phytase decrease rate was 60%. In addition, the enzyme can also reduce the viscosity of the volatility, which is advantageous for the absorption of the chicken against starch and protein.

[123 ] The characteristics of microbial fermentation method: It can achieve the effect of detoxification; it can produce detoxification effect on multiple anti-nutrition factors; can concentrate a lot of centralized processing and treatment, requiring process equipment conditions very simple.

123] Anti-nutrient factor has many kinds of feed, different feed anti-nutrient factors, and the same anti-nutrient factor is different from animals of different varieties, the same anti-nutrient factor is the same There is also a difference in the effects of different varieties of animals. Therefore, in practice, according to local conditions and actual conditions, a suitable removal method can be adopted to achieve good results. In the future, the chemical structure, activity characteristics, mechanism of the anti-nutrition factor in the feed should be determined to better eliminate the toxic ingredients in the feed.
