Premixed feed is a kind of homogenous mixture of many additives of the same kind or different types of additives in a certain proportion. Although the proportion of premixed feed in total feed is very small, it plays an extremely important role in the feeding effect of full price feed. The purpose of the production of premix is to make the effective components of the additive disperse evenly in the formulated feed after dilution and expansion.
1. Correctly understand the function of premix
Under the condition of large-scale feeding, full price compound feed must be provided to animals. In order to prepare a kind of full price compound feed, premix is necessary. The nutritional indexes of crude protein, essential amino acid, energy, calcium, phosphorus, etc. in the diet should be considered first, and then scientific and reasonable premix should be combined. Only in this way can it play its role in improving animal production level, reducing feed consumption and health care. In order to distinguish the role of various nutrients in animal nutrition, we should not overemphasize the nutritional and physiological functions of premix. Only when the main nutritional indicators in the diet are reasonable, can the role of premix be demonstrated.
2. Reasonable selection of premix
There are many kinds of premix sold in the market. When purchasing, we must proceed from the reality and select the premix according to the situation of feed raw materials that we have. If there are both energy feed raw materials and protein raw materials, the compound premix with 4% ~ 5% addition can be selected (Jindian series and daduosanbao Series); premix products produced by manufacturers with strong technical force, complete product specifications, stable quality and considerate after-sales service should be selected; according to the types of local agricultural and sideline products, the formula suitable for their own basic material types and characteristics should be selected Type.
3. Strict quality identification
When purchasing premix, the products of regular manufacturers (Beijing Yinuo tianbang) should be preferred, and carefully check whether the packaging is standard and whether the label content is complete. The following items shall be indicated on the label: product name, application stage, main ingredients, type and content of drug additives, proportion of addition, instructions for use, production date, shelf life, executive standard, approval number, name, address and telephone number of the manufacturer. The sensory evaluation of the product quality should also be made. The qualified premix should have the same particle size, uniform color, and no peculiar smell, mildew, moisture absorption and caking. In the use of premix, the premix should be selected according to the type of livestock and poultry and different growth stages, and the species and applicable stage indicated on the label should be carefully checked.
4. Accurate dosage and even mixing
It should be mixed with other feeds according to the instructions. The amount of premix should account for 0.5% ~ 6% of the total amount of compound feed. It should be weighed accurately when used. Because the dosage is too small to achieve the desired effect, too much dosage is not only a waste, but also easy to cause poisoning! The premix must be well mixed with other feeds before feeding. And the best with the feed, with a good feed should be used up in a day.
5. Correct storage
Pay attention to the storage time and conditions of premix to keep it fresh. The unbacked premix should be stored in a ventilated and dry place; it should be used up as soon as possible after opening the bag, and should not be stored for a long time. Attention should be paid to sealing during use to avoid moisture, otherwise the content of active ingredients will be reduced.
Premix is a high-tech product based on animal growth and nutrition needs, considering the influence of various related factors, adopting advanced equipment and technology, reasonably matching and evenly mixing various vitamins, trace elements, amino acids and growth promoting factors through carriers and diluents. It contains most of the nutritional needs. When mixed with protein and energy feed, it can play a balanced and efficient role in nutrition and fully meet the nutritional needs of animal growth and production. Therefore, only when farmers choose and use premix correctly, can they give full play to their nutritional function.
