Results from several experiments were reviewed to collect information on the value of piglet “needle-teeth” clipping. The incidence of facial and udder lesions generally is increased when teeth are left intact. However, there is no evidence that these lesions affect piglet mortality or weaning weight. Thus, based on the conditions of these experiments, there is no strong justification for teeth clipping. Many producers have abandoned teeth clipping. Besides saving labor, they report having fewer poor doing piglets and joint infections that can result from teeth clipping. Some producers have tried to stop clipping, but because of greasy pig disease problems they have resumed. Producers who have not tried to stop clipping are advised to clip only half of the litters in a few farrowing groups and observe for possible problems.
