title: Experimentally induced pine needle abortion in range cattle.
abstract: Pine needle-induced abortion in cattle is a serious problem in many areas of western United States and Canada. Field observations on pine needle abortion indicate that this condition is stress related. The results of this research indicate that the pine needle-induced abortion occurs much more readily if cows are under stress.
