    About 10-30days.
  • Modes of transport

    By air, by sea or by train.

  • Payment Term

    Pre-T/T OR LC at sight.
  • Packaging and storage

    Most pre-mixed packaging bags use three-in-one paper bags, which have the advantages of waterproof, light-proof, no leakage and not easy to damage. Generally 20-25 kg/bag. Since the premix contains a variety of active micro-components, the chance of their interaction will increase, so care should be taken to prevent moisture during storage.
  • Measurement and mixing

    For the measurement of micro-components, electronic scales should be used, accurate to 0.01 grams, and large amounts of raw materials can be used on scales. There are many kinds of mixers. Ordinary vertical mixers are prone to shortcomings such as automatic separation and slow discharge speed due to their slow feeding speed. It is best to use a horizontal double ribbon mixer or a cone mixer.
  • Amino acid addition problem

    Many experiments have confirmed that adding rumen bypass methionine and lysine can increase milk production and economic benefits. This can be added by dairy farms according to specific conditions.
  • Stability of trace components

    Under normal storage and use conditions, the physical and chemical properties of trace elements, vitamins and other components in the premix are stable, but when the moisture content is high, the stability is poor and the loss rate is large. Strictly control the water content of the premix, preferably not more than 5%.
  • Production technology

    Prevent and reduce the loss of active ingredients and ensure the stability and effectiveness of the premix. Choose raw materials with good stability. In terms of vitamins, it is better to choose stabilized raw materials; when using sulfate trace elements, the crystal water should be minimized, or oxides should be used instead, organic trace elements can also be selected; control choline chloride The amount of alkali, because of its strong water absorption, has a destructive effect on vitamins; vitamins should be added in excess, especially when the storage time exceeds 3 months; good quality antioxidants, anti-caking agents, and anti-fungal agents should be added.
