The famine of itself feels with full to adjust feed intake and Feeding time, avoid due to artificially feed it is improper caused by polyorexia or mistake
Full phenomenon.Simultaneously can also avoid due to same column pig size and deposit and pig foraging behaviour there are individual difference and caused by adopt
Energy imbalance is eaten, but because pig can absorb feed at any time, pig is known from experience less than strong hunger, therefore can often be shown
It is off one's feed, each feed intake of pig of free choice feeding is relatively low, is unfavorable for the development of stomach and intestine volume, then influences whether adopting for the stage of fattening
Appetite then influences performance, and pig inevitably takes feed a part outside slot out of during feeding, and with regard to animal person's character
For, there is material in slot, under normal circumstances, it will not eat the material for being sprinkled upon ground, will result in a large amount of feed waste in this way, cause
The excessively high reason of cost；Limitation feeding is reasonable arrangement feeding time and scale of feeding, and pig is made to keep more vigorous appetite, and
Facilitation can be played to the development of the stomach and intestine volume of pig, and limit clear advantage there are one feedings, be to find in time
Sick pig, when feeding less than trough rim material feeding must be sick pig undoubtedly, therefore poultry raiser is contributed to find that sick pig reduces the death rate in time,
