Characteristics of suckling piglets

First, the suckling piglets with rapid growth and strong material metabolism are still in the early stage of life, and the intensity of absolute growth (the absolute value of weight gain per unit time) is very small, but the relative growth (within a certain period of time, the multiple of weight gain) is very strong, plasticity is also great, so the feed reward is very high. At this time, if the growth and development is hindered, it is easy to become a "stiff pig"; second, the various physiological functions of suckling piglets are not mature, easy to suffer from various diseases, but also easy to be crushed to death, freeze to death and starve to death. The mortality of piglets after birth accounts for most of the mortality in the whole life cycle.
