The survival rate needs to be controlled above 96%. At present, the assessment of breeding pigs in different scale pig farms is not the same. According to my understanding, the survival rate of suckling piglets needs to be controlled above 96%, the survival rate of suckling piglets needs to be controlled above 96%, and the survival rate of fattening pigs needs to be controlled above 98%, which is still an ideal production achievement. Judging from the current price of live pigs, it is difficult to make money if the pigs in the three stages do not reach this value.
