Rational use of Deer Feed Additives

The classification of feed additives is divided into nutritional additives and non-nutritional additives. The commonly used nutritional additives for deer are: mineral additives, vitamin additives, amino acid additives, etc.; commonly used non-nutritional additives are: Chinese herbal medicine additives, fungicidal agents, silage improvers, enzyme preparations, antibiotic additives, appetizers and so on. There are many kinds of feed additives, their properties are different, and the dosage is very small. it is not only technically difficult to use feed directly, but also difficult to ensure the effect. Generally, additives are added to carriers or diluents to produce premixtures of all kinds of additives, and then used in compound feed. For deer, additives are not only optional, but also indispensable.

Correct selection of additives is recommended to buy regular manufacturers or research institutes or universities and other scientific research products, in order to achieve the purpose of safety and efficiency. The Deer Nutrition Research Group of the Special products Research Institute of the Chinese Academy of Agricultural Sciences is the only unit in China that specializes in the nutritional needs of antler deer, deer feed premix, deer feed additives and efficient feeding techniques. Nutrition regulators for deer in many physiological periods have been developed to meet the needs of calcium, phosphorus and other trace elements and vitamins in different physiological periods of deer. The application effect is excellent.

The usage (1) is based on a good basic diet formula. The effect of deer feed additive will be obvious only when the composition of protein, energy and concentrate / roughage ratio of antler deer diet is reasonable. In other words, feed additives can not replace the basic materials. (2) prevent blindness. It should be added in different regions and pertinently, for example, adding selenium to deer in selenium-deficient areas is effective, while adding selenium to antler deer in rich-smashing areas will cause poisoning, as well as other elements such as copper and cobalt. The key is to do a good test and targeted purchase. In addition, some people put too much emphasis on the comprehensive addition of vitamins, but do not realize that some vitamins, as ruminants, deer can be synthesized by themselves, which will cause a lot of waste. Therefore, according to the feeding standards of antler deer and the nutritional composition of local feed, additives should be used according to the principle of what is missing. (3) do not use additives from multiple manufacturers at the same time. Most of the feed additives for deer are compound, and many kinds of compound additives are used at the same time, which not only increases the cost, but also causes improper proportion because of different formulations, and even poisoning due to some elements exceeding the standard. (4) attention must be paid to the incompatibility between additives. When it is not necessary to make a comprehensive additive premix, do not mix minerals and vitamins in advance, and should be added in stages when full-price diets must be made, and cannot be stored for a long time. When it is necessary to make a comprehensive additive premix, vitamins and carriers must be added in excess, and the water content must be less than 5%. Choline chloride and VA, VD, VK, calcium pantothenate and calcium phosphate should not be added at the same time, otherwise the activity of various components will be reduced and the nutritional regulation of feed additives will be weakened. (5) it was added according to different biological periods. Due to the different sex of deer and the different physiological needs of different biological periods, additives with definite stages and definite effect should be used. (6) Additives should avoid fermentation or boiling. (7) add strictly according to the instructions. Adding additives to the concentrate must be added according to the instructions. A large dose can cause waste or poisoning. Additives should be mixed with concentrate feed and stirred evenly, otherwise some deer eat less or can not eat, and some deer eat too much, which will also cause waste or poisoning. (8) keep it correctly. Single-type additives should be kept under the conditions of drying, sealing, avoiding light and low temperature, and the preservation time should not exceed the shelf life.
