Embodiment 1
[0017] Embodiment 1 provides an extruded granular compound feed, including: energy feed raw materials, protein feed raw materials, compound premixed feed and auxiliary materials.
[0018] The energy feed material comprises: one or more of 5-15 parts by weight of oil bran, 20-30 parts by weight of rapeseed meal and 15-25 parts by weight of flour.
[0019] Preferably, the energy feed material includes 10 parts by weight of oil bran, 28 parts by weight of rapeseed meal and 19.5 parts by weight of flour.
[0020] The protein feed material comprises: one or more of 3-10 parts by weight of fish meal, 3-10 parts by weight of corn gluten meal and 20-35 parts by weight of soybean meal.
[0021] Preferably, the protein feed material includes 5 parts by weight of fish meal, 5 parts by weight of corn gluten meal and 28 parts by weight of soybean meal.
[0022] The extruded granular compound feed contains 2 parts by weight of compound premixed feed; and the compound premixed feed includes...
Embodiment 2
[0045] On the basis of Example 1, this Example 2 provides a production method of extruded granule compound feed, by mixing energy feed raw materials, protein feed raw materials, compound premixed feed and auxiliary materials together in a certain weight ratio, It is made by superfine pulverization, expansion processing, aging and drying.
[0046] The drying temperature is not higher than 100°C.
[0047] Specifically, for the specific components and implementation process of the extruded granule compound feed, refer to the relevant discussion in Example 1, and will not be repeated here.
[0048] The production process of the extruded granule compound feed in this embodiment is as follows: through ultrafine pulverization, the cell wall of the raw material is broken, more nutrients are released, and the utilization rate of the feed is improved; a twin-screw extruder is used to expand greatly; Quality, fully mature; use multi-layer constant temperature dryer, control temperature ...
