1. Determine the amount of various feed additive raw materials based on beef cattle breeding standards and guidelines for use of feed additives. The amount of trace elements and vitamins specified in the feeding standards are usually used as added amounts, and reference can be made to the balance between reliable research and practical practices, and the types and quantities of additives added. 2. Raw material selection. The raw material's biological titer, price, and processing technology require the selection of trace element raw materials. The main trace elements were identified, and impurities and other elements were identified for use. 3. Calculate the amount of commodity material required in the premix according to the trace elements in the raw material, the content and the potency of the vitamin and the active ingredient, the required amount in the premix, and the like. Its calculation method is: Pure raw material = required amount of a trace element / element content in pure product (%) Commodity raw material volume = pure raw material volume / high product raw material effective content (or purity) 4. Determine the amount of carrier. Calculate the amount of carrier based on the proportion of premix in the compound feed. It is generally considered that the premix is ​​suitable for 0.1%-0.5% of the full-price compound feed. The amount of carrier is the difference between the amount of premix and the amount of raw material for commercial additives. 5. List the formula for the production of feed additive premix. Beef premix recipe design example (I) Formulation design example of microelement premix Take the formula design of the premix of trace element in fattening beef cattle as an example: 1. Determine the amount of trace elements according to the feeding standards. The trace element requirement for fattening cattle from the beef cattle raising standard in China is the amount per kilogram of dietary supplement; copper is 8mg, iodine is 0.5mg, iron is 50mg, manganese is 40mg, selenium is 0.1mg, zinc is 30 mg, 0.1 mg of cobalt. 2. Trace element raw material selection. There are many feed additives for trace elements in production. The chemical structure, molecular formula, element content, and purity are all different, and they are selected according to actual conditions. 3. Calculate the amount of raw materials for the commodity. The amount of raw material per kilogram of full-price compound feed is equal to the requirement of a certain trace element/the content of this element in pure product/purity of commodity raw material The amount of commodity material per ton of full-price compound feed is equal to the amount of raw materials per kilogram of full-price compound feed*1000. 4. Calculate the amount of vector. If the premix occupies 0.2% of the full-price batch, the amount of carrier in the premix is ​​equal to the difference between the amount of premix and the amount of raw material for the trace amount of salt. That is: 2kg-0.54629kg=1.45371kg. (B) Vitamin additive premix formulation design as an example: Lishida Red Vinegar,which is brewed from high quality rice and other ingredients,is usually used for pickling,making salads and cooking.Also,it's great for seasoning the seafoods such as crabs and clams.You can add directly into noodles for fresh taste too.It's available for bulk wholesale and warm welcome friends who owns supermarkets and restaurants for cooperation.
