How to choose premixes and points for use

The premix contains functional additives such as vitamins, trace elements, amino acids, and other nutrients and drugs necessary for the growth and development of livestock and poultry. Most of the specifications are 1% to 5%. After purchase, the farmers only need to follow the recommended formula. High-quality raw materials are crushed and mixed to become full-priced feed. As long as it is used rationally, the premix can guarantee the quality of the feed and at the same time reduce the production cost and achieve good results.

However, in the actual production of feed, farmers have many problems due to their poor understanding of premix, which affects the use of premix, and has a negative impact on the enthusiasm of farmers for using premix.

1, using materials carefully

At present, there are many brands of premixed materials, and the quality is different. The types and quality of the pharmaceutical additives in the premixes are also quite different. Therefore, the premixes can not only see the price, but more importantly the quality, and the credibility and processing must be selected. Good equipment, strong technical force, product quality and stable manufacturers and brands.

2, special materials

Different premixes are formulated according to the nutritional needs of different livestock and poultry at different stages of growth and development. When used, the breeds and growth stages of livestock and poultry raised must be consistent with the applicable scope of the premix, that is, they should be used only for special materials and cannot be mixed and cannot be used universally. In production, pig premixes have been used on cows to cause death;

3, strictly in accordance with the prescribed dose

The amount of premix is ​​carefully designed and prepared by the premix plant according to different types of livestock and poultry, and different growth stages. In particular, a large proportion of premixes containing calcium, phosphorus, salt, and animal protein must be used. The prescribed ratio is added. Some farmers use the premix as a seasoning and the amount is insufficient; some farmers use the premix as a panacea and increase the amount of blindly; some use mixed products from different manufacturers. Unsatisfactory dose regulation will result in unbalanced animal nutrition, which not only increases the cost of feeding, but also affects the growth and development of livestock and poultry, and even poisoning.

4, rational use of recommended formula

The premix purchased by the farmer has a recommended formula on the feed label or product packaging bag. This formula is a general formula that can prepare the various raw materials of the formula and can be prepared according to the recommended formula. You can also make full use of the advantages of local raw materials, and ask the technical personnel of the premix manufacturer to give on-the-spot guidance. Don't adjust the formula yourself, otherwise the nutritional imbalance of the full price feed will be affected.

5, grasp the quality of feed ingredients

The amount of premix is ​​only 1% to 5%, and 95% to 99% of most of the ingredients are feed ingredients, so the quality of the raw materials is very important. At present, the quality of feed ingredients in the rural market is very different. Therefore, we should try our best to select raw materials from well-known and reputable manufacturers.

6, pay attention to the raw material grinding size

Raw materials with larger granularity, such as corn and soybean meal, must be crushed before use. The feed grain size of pigs should be 500~600.

7. The coefficient of variation of the feed mixing uniformity is usually not greater than 10%.

8, correctly feeding

The premix can not be fed alone, and must be fed after formula mixing. It cannot be fed after water or steaming. The materials should be changed step by step, and the refueling should be completed in about 1 week, so as to reduce the stress caused by refeeding such as reduced feed intake and growth.

9, safekeeping

When the vitamins, enzyme preparations and other components in the premix are stored improperly or stored for too long, the potency will be reduced, so they should be stored in shading, low temperature, and dry place, and they should be used as soon as possible during the shelf life.
