Types of feed for pigs and their characteristics


25252525.jpg




Feed typepeculiarityFeeding amount
Qingyu Fee- Juicy, palatable, easy to digest and absorb
- Rich in protein and vitamins
- Contains certain minerals and unknown growth factors		- After weaning, piglets 1-2 kg/day
- 30-50 kg medium pigs 2-4 kg/day
- 50 kg or more large pigs 4-6 kg/day
Juicy feed- Rhizomes (e.g. fresh sweet potatoes, radish, taro)
- Melons (e.g. pumpkin, zucchin)
- High in water, less crude fiber, high
in nitrogen-free extract - More carotene, low in protein and minerals		- 瓜类可作母猪催奶饲料
- Rhizome 类可作催肥猪饲料
roughage- By-products
such as straw and husks - bulky, high in fiber (more than 18%), indigestible
- lack of protein, vitamins and minerals		- It should not exceed 3-5%
when untreated - it can be increased to about 15% after roughage degrader treatment
Concentrate feedEnergy Feed:
- Cereals (corn, rice, sorghum, barley), tapioca flour, sweet potato flour, bran, etc
.- High starch content (75-85%), low protein (8-10%), high phosphorus and calcium, lack of chlorine and sodium
- Dosage 40-60%
protein feed:
- Bean cake, fishmeal and other
others:
-   Sugar, bone meal, shellfish powder, premix, etc		-

Cattle Feed Pellet Production Line:


The name of the systemdescription
1. Raw material receiving systemThe first step in the process is to receive the raw materials. This is usually done using a series of conveyor belts or augers, which transport the material from the delivery truck to the storage silo. The raw materials are then stored until they are needed for production.
2. Cleaning and screening systemBefore processing raw materials, they must be cleaned and filtered to remove any impurities or foreign matter. This is usually done using magnets, sieves, and other separating devices. Once cleaned and filtered, the material is ready for processing.
3. Grinding systemThe cleaned and filtered raw material is then fed into a grinding system that breaks down the material into smaller particles. This is usually done using a series of hammer mills or roller mills. The ground material is then fed into the mixing system.
4. Mixing systemThe ground material is then mixed with any necessary additives, such as vitamins, minerals, or other nutrients. The mixture is then thoroughly mixed to ensure that the ingredients are evenly distributed. The mixed material is then fed into the pelletizing system.
5. Granulation systemThe mixed material is fed into a pelletizing system that uses a series of dies and rollers to shape the material into uniformly sized particles. The pellets are then cooled and dried to remove excess moisture.
6. Cooling systemThe pellets are then cooled to room temperature using a series of fans and cooling plates. This helps prevent particles from clumping and makes them easier to handle.
7. Screening systemThe cooled particles are then screened to remove any particles that are too large or too small. The screened pellets are then fed into the packaging system.
8. Conveyor systemThe screened pellets are then transported to the packaging system using a series of conveyor belts or augers.
9. Packaging systemThe final step in the process is to pack the pellets for dispensing. This is usually done using a series of baggers that fill the pellets into bags of various sizes. The bags are then sealed and labeled, and then loaded onto pallets for shipping.
