Mixed feed is a homogeneous mixture prepared with multiple additives of the same type or multiple additives of different types in a certain proportion. Although premixed feed accounts for a small proportion of complete feed, it plays an extremely important role in the feeding effect of complete feed. Scientific premix feed formulation is the key to premix production. To further deepen everyone's understanding of premixed feed, this article will further introduce the characteristics and use of premixed feed.
The purpose of premix production is to make the active ingredients of the trace component additives evenly dispersed in the compound feed after dilution and expansion.
The Premix has the following characteristics:
①Complex composition. Good quality premixes generally include 6 or 7 trace elements, more than 15 vitamins, 2 amino acids, 1 to 2 drugs, and other additives (antioxidants, antifungal agents, etc.). Various feed additives have different properties and functions;
②The dosage is small and the effect is great. Generally, the proportion of premix in compound feed is 0.5%~5%. Although the dosage is small, it has a great effect on improving animal production performance, improving feed conversion rate, and preserving feed;
③Cannot be fed directly. The concentration of active ingredients in the additives in the premix is very high, generally dozens to hundreds of times the amount required by the animals. If fed directly, it can easily cause animal poisoning.
The premix has four main functions:
① It can make the trace components of additives evenly distributed in the compound feed;
② Compensate and improve the undesirable characteristics of trace components through the pre-mixing process, such as instability, water absorption, electrostatic adsorption phenomenon, etc.;
③Standardize the level of additives;
④ Simplify the production process of general feed processing plants and reduce investment.
Under intensive large-scale breeding conditions, animals must be provided with full-price compound feed. To prepare a full-price compound feed, premixes are essential. Nutritional indicators such as crude protein, essential amino acids, energy, calcium, phosphorus, sodium, and chlorine in the diet should first be considered, and then combined with scientific and reasonable premixes. , only in this way can it play its role in improving animal production levels and reducing feed consumption. It is necessary to distinguish the role of various nutrients in animal nutrition and their interrelationships. The nutritional and physiological effects of premixes cannot be overemphasized. Only when the main nutritional indicators in the diet are reasonable can the effects of premixes be demonstrated.
The premixes sold on the market vary from good to bad, and some have problems such as substandard quality and unreasonable formulas. When purchasing, you must proceed from reality and choose premixes according to the conditions of the feed raw materials you own and local conditions. If you only have energy-feed raw materials, you should choose a complete nutrient concentrate; if you have both energy-feed raw materials and protein raw materials, you can choose a compound premix with an addition amount of 4% to 5%; if you are a feed factory, you can choose Professional premix factories produce 1% to 3% composite premixes or 0.1% to 0.5% high-tech classified premixes. You can choose a formula type that suits the type and characteristics of your base materials based on the types of local agricultural and sideline products.
When purchasing premixes, products from regular manufacturers should be preferred, and carefully check whether the packaging is standardized and the label content is complete. The following items should be indicated on the label: product name, applicable stage, main ingredients, type and content of pharmaceutical additives, addition ratio, instructions for use, production date, shelf life, execution standards, approval number, production company name, address, phone number, etc. It is also necessary to make a sensory judgment on product quality. Qualified premixes should have the same particle size, uniform color, and no odor, mildew, moisture absorption, or agglomeration.
When using premixes, special premixes should be selected according to the types of livestock and poultry and different growth stages. You should carefully check the livestock species and applicable stages indicated on the label.
It should be fully mixed with other feeds and fed according to the instructions. Generally, the dosage of premix accounts for 0.5% to 6% of the total amount of compound feed. It should be accurately weighed when used. Too little dosage will not achieve the desired effect, and too much dosage will not only be wasteful but may also cause poisoning.
The premix must be fully mixed with other feeds before feeding. It is best to feed as needed, and the prepared feed should be used up at one time.
Pay attention to the storage time and conditions of the premix to keep it fresh. Unopened premixes should be stored in a ventilated, cool, dry place, and kept in categories; they should be used up as soon as possible after opening the bag, and do not store them for a long time. During use, please pay attention to sealing and avoid moisture, otherwise, the content of active ingredients will be reduced.
The premix is based on the theoretical basis of animal growth and development and nutritional needs, taking into account the influence of various related factors, using advanced equipment and technology, and rationally mixing multiple vitamins, trace elements, amino acids, and growth-promoting factors through carriers and diluents. High-tech products that are matched and evenly mixed. It contains most of the nutritional needs. When mixed with protein and energy feed, it can exert nutritional effects in a balanced and efficient manner and fully meet the nutritional needs of animal growth and production. Only by correctly purchasing and rationally using premixes can livestock producers give full play to their efficient nutritional functions.
