What age do piglets need water?
It is interesting to note that newborn pigs are able to drink water within the first 2 hours after birth, indicating a need for water in addition to that supplied by sow’s colostrum or milk. It is also essential to provide drinking water to suckling piglets that actively consume solid feed.
Why do we clip the teeth of new born piglets?
Importance of teeth clipping in young pigs The cuts to the sow’s udder also allow germs to infect the udder. In their fight to grasp the teat and suckle, piglets will also bite and injure one another. The simple practice of clipping the teeth as soon as possible after birth prevents these problems.
What do you do after piglets are born?
Split suckle. This involves removing part of the litter for one to two hour periods the first 12 hours after farrowing. For best results, remove the largest, strongest piglets for a one to two hour period during the morning and again in the afternoon, leaving the small piglets on the sow to nurse.
What is Farrow in pig?
Farrowing is a term specific to swine that refers to the action of giving birth. Another general term for this is parturition. Farrowing management begins months before piglets are born. Sometimes delivery timing is slower and sometimes two pigs will arrive at the same time.

When can I move sows after breeding?
It is critical that these events take place for the establishment of pregnancy. Due to animal flow on commercial farms, many producers move sows at 2 weeks after mating.
