2. Less before and more after the method: the amount of concentrate feeding gradually increases with the increasing age of the sow's gestation, because the fetal development is slow in the early stage, if a large amount of concentrate in the pregnant sow during this period will not only cause feed waste but also easily cause the sow to be overfat and affect the delivery. In the early stage, the diet is mainly composed of green coarse grains, and in the later stage, the fetus develops rapidly, and the proportion of concentrate is increased to meet the growth needs of the fetus.
It is mainly used for sows with good fat.

Hump method: the proportion of concentrate is like the hump of a camel, high on both sides and low in the middle, in the early stage, for slightly weaker sows, increase the concentrate content appropriately to restore it to the reproductive body condition as soon as possible, and reduce the amount of concentrate feeding.
