Consumption of ponderosa pine needles, as well as needles and bark from a number of other trees, can cause abortions in cattle. The abortifacient compounds in these trees are labdane resin acids, including isocupressic acid and agathic acid. Previous research has demonstrated that cattle conditioned to pine needles metabolize the labdane resin acids more quickly than naïve cattle. The results from that study indicated that changes had occurred in the rumen of conditioned cattle. Therefore, in this study, the changes that occurred in the rumen bacterial microflora of cattle during exposure to ponderosa pine needles were evaluated. Cattle were dosed with ground pine needles twice daily for 7 d. Rumen samples were collected on d 0, 3, 7, and 14 (7 d after treatment stopped) and ruminal bacterial microbiome analyses were performed. There were 372 different genera of bacteria identified in the rumen samples. Principal coordinate analysis indicated that there was a significant difference in the rumen bacterial composition between the time points. There were 18 genera that increased in abundance from d 0 to d 7. Twenty three genera decreased in abundance from d 0 to d 7. The results from this study demonstrated that exposure of cattle to pine needles caused a clear shift in the rumen microbiome composition. In general, this shift lasted less than 1 wk post exposure, which indicates that any prophylactic treatment to manipulate the ruminal metabolism of the abortifacient compounds in pine needles would need to be continuously administered to maintain the necessary microbial composition in the rumen.

Pine needle abortion is a naturally occurring condition in free-range cattle caused by the consumption of pine needles from select species of cypress, juniper, pine, and spruce trees. Confirmatory diagnosis of pine needle abortion has previously relied on a combined case history of pine needle consumption and detection of isocupressic acid in a sample from the dam. Stable metabolites of isocupressic acid include agathic acid, dihydroagathic acid, and tetrahydroagathic acid, which have been shown to be present in the serum of mature animals for a few days following consumption of pine needles. As maternal serum is infrequently submitted for diagnosis of cattle abortions, a diagnostic assay capable of confirming isocupressic acid exposure in other matrices would be desirable. To the authors’ knowledge, no previous investigations have indicated whether these stable metabolites of isocupressic acid cross the placenta or are detectable in fetal tissues. Therefore, the presence of agathic acid, dihydroagathic acid, and tetrahydroagathic acid was evaluated using gas chromatography-mass spectroscopy on fetal thoracic fluid and stomach contents collected from 2 aborted bovine fetuses with a recent herd history of pine needle consumption by the dams and a subsequent abortion outbreak in the herd. Only tetrahydroagathic acid was detected in the fetal thoracic fluid and fetal stomach contents. The current study encourages diagnosticians to collect fetal thoracic fluids to permit the detection of tetrahydroagathic acid in cases of suspected pine needle abortion.
