Twenty-five of 125 pregnant heifers in late-term pregnancy aborted after being introduced into a paddock containing numerous H. macrocarpa, C. arizonica and Casuarina cunninghamiana trees. There were no significant macroscopic or histological findings in the two fetuses analyzed. Abortifacient labdane acids were detected in the needles of H. macrocarpa (1.68%, D.W.) and C. arizonica (0.36%, D.W.) but none were found in C. cunninghamiana. aBOVINE ABORTION aISOCUPRESSIC ACID aPINE-NEEDLE POISONING aREPRODUCTIVE DISEASES1 aGARDNER, D.R.1 aBOABAID, F.M.1 aOLIVEIRA, L.G.S.1 aDE NAVA, G,1 aLÓPEZ, F.1 aRIET-CORREA, F. tToxicon, 15 July 2020, Volume 181, Pages 53-56.
