The premix contains functional additives such as vitamins, trace elements, amino acids and other essential nutrients necessary for the growth and development of livestock and poultry. The specifications are mostly 1% to 5%. After the farmers buy back, they only need to follow the recommended formula. High-quality raw materials, after being crushed and mixed, become full-price feed. As long as it is used reasonably, the premix can guarantee the quality of the feed, while reducing the production cost and achieving good results.
However, in the actual production of feed, farmers still have many problems due to insufficient understanding of premix, which affects the use effect of premix and attacks the enthusiasm of farmers to use premix.
1, carefully use the material
At present, the premix has many brands and different quality. The types and quality of the pharmaceutical additives in the premix are also very different. Therefore, the choice of premix can not only look at the price, but more importantly, the quality, the choice of high reputation, processing Manufacturers and brands with good equipment, strong technical strength and stable product quality.
2, special materials dedicated
Different premixes are formulated according to the nutritional needs of different growth stages of different livestock and poultry. At the time of use, the breeds of livestock and poultry and the stage of growth and development should be consistent with the applicable range of premixes, that is, special materials are used, they cannot be mixed, and they are not universal. In production, pig premixes have been used on dairy cows, causing cows to die;
3. Use strictly according to the prescribed dosage
The amount of premix is ​​carefully designed and prepared according to different livestock and poultry types and different growth stages, especially large proportions of premix containing calcium, phosphorus, salt and animal protein. The prescribed ratio is added. Some farmers use the premix as a seasoning, and the amount of addition is insufficient; some farmers use the premix as a panacea, blindly increase the amount added; some mix the products of different manufacturers. Unsafe doses will cause imbalance in the nutrition of the animals, which will not only increase the cost of feeding, but also affect the growth and development of livestock and poultry.
4, the rational use of recommended formula
The premixes purchased by the farmers have a recommended formula on their feed labels or product packaging bags. This formula is a general-purpose formula that can prepare the ingredients of the various ingredients in the recommended formula and can be formulated according to the recommended formula. You can also make full use of the advantages of local raw materials. Please consult the technicians of the premix manufacturers on site, and do not adjust the formula by yourself. Otherwise, the nutritional imbalance of the full-price feed will affect the use effect.
5, grasp the quality of feed ingredients
The premix is ​​only added in an amount of 1% to 5%, and 95% to 99% of the majority of the ingredients are feed ingredients, so the quality of the raw materials is critical. At present, the quality of feed ingredients in the rural market varies greatly. Therefore, the raw materials of manufacturers with high reputation and good reputation should be selected as much as possible.
6, pay attention to the crushing size of raw materials
Raw materials with larger grain size, such as corn and soybean meal, must be crushed before use. The grain size of pig feed is 500~600. It is better to
7. The variation coefficient of feed mixing uniformity of feeding should not exceed 10%.
8, correctly feeding
Premixes cannot be fed separately and must be mixed according to the formula before feeding. They should not be washed with water or cooked. When changing materials, it should be gradual, and the refueling should be completed in about 1 week to minimize the stress caused by refueling, such as reduced feed intake and decreased growth.
9, properly keep
When the vitamins, enzyme preparations and other ingredients in the premix are stored improperly or stored for too long, the potency will decrease. Therefore, it should be stored in a place where shading, low temperature and dryness are used, and should be used as soon as possible within the shelf life.
