Pines in general are toxic. Cattle and to some extent sheep that ingest needles, young shoots, or bark during pregnancy are prone to producing weak or dead calves, apparently because some compounds in pines disrupt reproductive hormones (Burrows and Tyrl, 2001). However, apparently Pinus strobus in particular has not been studied. Most of the problems associated with this toxicity are in western states where other species of pines occur. In areas where other winter browse has been exhausted, deer that ingest pines apparently do not suffer any symptoms of poisoning.
