Summary
Chick embryos can serve as an economical means to screen pine needle extracts for possible abortive components which affect cattle grazing alpine pastures. Lipid-like extracts from pine needles did not appear to be toxic to chick embryos, while carbohydrates components were toxic at low levels. Protein components were not screened in this study.
