Introduction of YIDUOZYME¨D9980:

î        YIDUOZYME¨D9980 is a multi-activity feed enzyme for aquatic animals developed and produced by Guangdong VTR Co., Ltd.

î        YIDUOZYME¨D9980 chooses the enzymes reasonably according to the digestive and physiological characteristics of the aquatic animals.

î        YIDUOZYME¨D9980 includes non-starch polysaccharidase to eliminate anti-nutritional factors contained in the aquatic feed ingredients such as wheat middling.

î        The formulation of YIDUOZYME¨D9980 is more rational, with more enzymes and better performance.

î        YIDUOZYME¨D9980 can prevent eutrophication.

Designing principle of YIDUOZYME¨D9980 formula:

 The digestive and physiological characteristics of aquatic animals determine the groups and activity of enzyme used.

î        The digestive tract of aquatic animals is relatively short, and the length  of intestines is only 1/3 or 1/4 of the body in some species. The retention time of digesta is relatively short; as a result, the digestion of feed is rather  uncompleted.

î        The differentiation of the stomach and intestines of herbivorous or omnivorous fish is not obvious. There is no real stomachs or the secretion of gastric juice in fishes. The fishes cannot secrete sufficient digestive enzymes such as proteinase and amylase. As a result, the digestion and absorption of nutrients  is influenced.

î        In aquatic feed, the material such as the wheat middling contains anti-nutritional factors such as the non-starch polysaccharide that can reduce the  utilization of the feed.

î        More vegetable feed materials replacing the fishmeal leads to the reduction of the feed digestibility, and probably causes some diseases, such as enteritis.

This shows that enzymes for aquatic animals should mainly be digestive ones, especially the proteinase and amylase with high activity, and the non-starch polysaccharidase as a supporting one.

The living environment of the aquatic animals determines that the multi-activity feed enzyme has an excellent effect.

The water quality is critical to aquaculture.  The aquatic feed has a high content  of protein, but its digestibility is very limited. The addition of multi-activity feed enzyme in feed can improve the digestibility of nutrients, minimize the excretion and simultaneously, reduce the content of undigested nutrients in feces. Therefore, the pollution to the water is reduced, which ensures the sustained development of the aquaculture.

The multi-activity feed enzyme  formula of YIDUOZYME¨D9980 for aquatic animals:

YIDUOZYME's advantages:

î        Enzyme species are complete and designed according to the specific requirements of fishes.

î        ISO 9001 in the enzyme production is maintained throughout the whole process.

î        The formula of enzyme is designed reasonably conforming to the digestive physiological characteristics of animals and the feed materials used.

î        Adopt advanced modern bioengineering technologies to produce the main enzyme with high activity and  complete enzyme system.

î        Advanced post-treatment technologies: ensure that the products can be used in general feed manufactured conditions.

î        Scientific and strict compounding technologies: ensure the product¡¯squality stable and reliable.

Applied effect of YIDUOZYME¨D9980:

Addition of YIDUOZYME¨D9980  to the feed can increase the ADG of tilapias by 64.8%,  plumpness by 6.55% and per mu yield by 20.3%,while reducing the feed/gain by 31.7%.

Addition of YIDUOZYME¨D9980 can improve the ADG of carps by 29.63%,  plumpness by 17.21% and per mu yield by 25.53%,while reducing the feed/gain by 28.33%.

Addition of YIDUOZYME¨D9980 can improve the ADG of catfish by 43.1%, plumpness and per mu yield by 7.36% and 40.77% respectively, while reducing the feed/gain by 30.75%.

Addition of YIDUOZYME¨D9980 can increase the ADG of eels by 35.77%, plumpness  by 8.36% ,and per mu yield by 22.3% ,and reduce the feed/gain by 13.65%.

YIDUOZYME¨D9980 can solve the following problems:

î        Improve the digestibility of nutrients, reduce their excretion to the water, prevent the pollution and ensure the sustained development of aquaculture.

î        Supplement exogenous digestive enzyme such as proteinase, amylase to improve the nutrient digestibility of the aquatic animals.

î        Add exogenous enzymes such as xylanase, which the aquatic animals cannot secrete.

î        Minimize the adverse effects of anti-nutritional factors; reduce the digesta viscosity of intestines to improve the digestibility of nutrients.

î        Add digestive enzymes with high concentration and high activity directly to improve the digestibility of special aquatic animals.

î        Increase the weight gain, improve the plumpness, reduce the feed variation, and increase the output per unit area.

î        Eliminate anti-nutritional factors in the feed, maintain the stability of feed quality, and minimize the variation of feed ingredient.

î        Increase feed conversion rate and prevent the environmental pollution.

Usage

Usage in lowering the cost

More vegetable protein materials can be used to substitute for animal protein materials and more crude materials can be used to substitute  for fine materials, so to provide a very economical solution for least costing formulation of feed.

Usage in improving the quality of the products

Improve  the product quality while keeping the present formula unchanged, ensure the quality of

products and increase the market competitiveness.

Usage rate

In general, the 1 kg/ton is preferred, but you can change it according to the feed formula, the range should be limited between 0.5-1.2 kg/ton. The technicians of our company could offer technical support and give suggestion for the specific manipulation .

Precautions

Avoid moisture; if there is remainder after used, the inner and outer packages should be tightened. Package; Transportation; Storage.

î        The standard package is 25kg/ bag.

î        Keep in cool, dry and dark places, and away from toxic substances.

î        Guaranteed period: 12 months
