(1) Sensory changes of raw materials (soybean meal, peanut meal)-from different suppliers (factories).　　

(2) Incorrect use of raw materials (Kushikura).　　

(3) Due to the shortage of raw materials, the structure of formula raw materials has changed.
　
(4) The head and tail of the warehouse are fed into the finished product, and the residual materials of the equipment are mixed into the finished product.

2. Solution:

(1) Stabilize the source of raw materials and pay attention to the stability of the sensory quality of raw materials.
　　
(2) Stable formula structure to avoid raw material shortage. 　　

(3) The raw materials for pig feed are exclusively stored and used to prevent confusion with poultry feed.
