Technical essentials of fattening and raising with hangers

In feeding, the use of "three stages" and "two maintenance" is to divide the whole fattening period of pigs into three stages: piglets, shelf pigs and fattening. Concentrate the planned concentrate on the two stages of piglet and fattening, and feed more green coarse feed and less concentrate as much as possible in the shelf pig stage. "two maintenance" is to enter the shelf pig stage, there is a transition period, shelf pigs into the fattening period also has a transition period. This method can save concentrate and reduce feed cost, but it has the advantages of prolonged feeding period, slow growth rate and low feed reward, which is not conducive to large-scale feeding and is rarely used in areas with better feeding conditions.
