The ponderosa pine is also called the blackjack pine, western yellow pine, yellow pine and bull pine. Isocupressic acid is a diterpene acid present in a variety of conifer needles. /=> $n18 r, Monterey cypress is known to cause abortions in cattle in New Zealand and southern Australia and contained ICA levels of 0.89%1.24%. Version: 2.0.0.0. Discarded Christmas trees have been known to cause abortions in cows. They may be used in teaching, printed, downloaded, or copied, provided it is in an At 15%30% of the diet, pine needles have been shown to alter rumen microflora and affect rumen fermentation (Pfister etal., 1992). Cogswell, C., & Kamstra, L. D. (1980). This article about an organic compound is a stub. Failure of implantation by 124 hr postcoitum in bred mice fed aqueous or acetone extracts of ponderosa pine can be used as an index of the risk involved in grazing ponderosa pine ranges, but cannot be used to predict losses. Severe winter weather often leads to conditions in which cattle mingle under trees to escape wind and snow. Isocupressic acid metabolites include imbricatoloic acid, agathic acid, dihydroagathic acid, and tetrahydroagathic acid (Figure 51.7). Ingestion by cattle of pine needles (Pinus ponderosa) containing isocupressic acid (also possibly present in the vegetation of some junipers and cypresses) results in late-term abortion (Cheeke, 1998). h\ Robert W. Coppock, Margitta M. Dziwenka, in Reproductive and Developmental Toxicology (Third Edition), 2022. 46.7). Calves born after 255days of gestation will often survive with extra care but need to be supplemented with colostrum and milk from other sources until the dam begins to lactate.

Cows with retained fetal membranes may need antibiotic therapy to avoid uterine infections. Warning:Pine Needle Tea, and eating Pine needles, may be harmful to unborn babies. Other types of pine can cause digestive problems in cats and dogs. Other labdane resin acids found in pine species and suspected to have abortifacient activity. However, the changes are very transient, as the rumen microflora returns to preexposure composition within 7days after exposure is stopped.

Late-term abortion occurs 214 days following heavy consumption of green or dry pine needles and results in up to 75% of exposed cows aborting or delivering dead or weak calves (Cheeke, 1998; Burrows and Tyrl, 2001; Casteel, 2007). Metabolism studies using the cytosolic fraction of bovine liver homogenates determined that ICA is rapidly metabolized to agathic acid and dihydroagathic acid with an elimination half-life of 15min (Gardner etal., 1999). Kip E. Panter, Dale R. Gardner, in Biomarkers in Toxicology (Second Edition), 2019. The aborted calves may survive if the abortion occurs in late gestation; however, they are small and weak, may not suckle, and generally require extensive care and treatment to survive. A study examining the effects of dietary variables on consumption of pine needles and parturition concluded that (1) feeding high levels of protein increased pine needle consumption but not abortion rate, (2) weathered or aged pine needles had activity equivalent to or greater than that of fresh needles, and (3) feeding corn silage to cows prevented pine needle consumption. Concentration of isocupressic acid and related metabolic compounds from selected species and locations. Under ideal conditions, it grows to heights of more than 60m and 1.52.5m in diameter. In another study, uterine blood flow in cows fed pine needles decreased progressively, declining to 25.5% of baseline by the day of premature parturition.22 The evidence suggests that consumption of pine needles induces a progressive reduction in uterine blood flow to the gravid horn and that this reduction causes the onset of premature parturition accompanied by normal prepartal changes in steroid secretion. endstream endobj 74 0 obj <>stream The University of Arizona Libraries | 1510 E.

During early growth, the bark is dark brown to black, hence the name black jack pine. Ponderosa PNs are not abortifacient in goats or sheep; ICA was not abortifacient in goats when administered orally or i.v. Although we believe these abietane-type resin acids may contribute to the occasional toxicoses reported in the field, we do not believe they contribute to the abortions. Alteration of this image in any form is restricted. Currently, recommendations to remove pregnant cattle in the last trimester of pregnancy from Ponderosa pine-infested pastures or to erect fencing around pine trees are the only preventive measures to ensure no losses from grazing pine needles. A gestation study verified results from the implantation experiment, as few mice fed pine needle extracts delivered normal litters. h(&E c00BCn LyS84-z7Z!l6ZR,XkbBH|\"m0K#U/D ?

No toxicity has been demonstrated from ICA or ICA derivatives; however, the abietane-type resin acids present in PN, and found in high concentrations in the new growth tips, were shown to be toxic and abortifacient at high doses when administered orally to cattle and toxic in goats and hamsters, causing nephrosis, edema of the central nervous system, myonecrosis and gastroenteritis (Stegelmeier et al., 1996). Metabolism studies using homogenates of bovine liver determined that ICA is rapidly metabolized to agathic acid and dihydroagathic acid with a t12 of 15 minutes (Gardner et al., 1999). Blackjack Pine, Western Yellow Pine, Bull Pine, Rock Pine, Early Detection & Distribution Mapping System. Cattle generally graze pine needles during storms with increased snow, wind, cold, changes in feed, or hunger. Frequently, mice receiving the concentrated aqueous extract had diarrhea and decreased feed intake.

The ponderosa pine is a hardy tree that is used extensively as timber. Current and future research focuses on metabolism of the abortifacient labdanes, mechanism of action of the induced parturition, and treatment of premature calves and retained fetal membranes to ultimately reduce losses for livestock producers. Tim J. Evans, in Veterinary Toxicology, 2007. Isocupressic acid (ICA), the abortifacient compound in Ponderosa pine needles and two ICA derivatives, succinyl and acetyl ICA. Figure46.7. STAN W. CASTEEL, in Current Therapy in Large Animal Theriogenology (Second Edition), 2007. Similar metabolism occurred in goat, sheep, pig, guinea pig, and rat liver homogenates although the guinea pig and rat livers were less efficient at metabolizing the compounds. was developed using embryo implantation and gestation in laboratory mice as the basis of the assay. PN consumption increases during cold weather, with increased snow depth, and when other forage is limited (Pfister etal., 1998; Cook etal., 2010).

Consortium of California Herbaria - https://ucjeps.berkeley.edu/consortium/about.html GBIF - https://www.gbif.org Rich in oil, the seed has a slightly resinous flavor. FIGURE 51.7. Cattle readily graze PN (both PN litter on the ground and green needles from trees), especially during the winter months in the western USA.

Toxic extracts in ponderosa pine needles that produce abortion in mice. Ponderosa pine needles are not abortifacient in goats or sheep; ICA was not abortifacient in goats when administered orally or i.v. In observed field cases of poisoning, the cows appear to have no other signs of intoxication other than abortion and its sequelae. Specific compounds include abietic acid, dehydroabietic acid, and other related compounds (Stegelmeier etal., 1996). Long-term endocrine disruptions in the offspring, if they occur, are not known. Currently, recommendations to remove pregnant cattle in the last trimester of pregnancy from ponderosa pine-containing pastures, or to erect fencing around pine trees are the only preventive measures to ensure no losses occur from grazing PNs. Some calves from affected dams are born weak but may survive with adequate care. pine dyeing water dye needle bark sky under living ponderosa A separate toxic syndrome has been described in addition to abortion in which the abietane-type diterpene resin acids cause depression, feed refusal, weakness, neurological problems, and death. Other pine trees that contain isocupressic acid include the lodgepole pine (Pinus contorta), common juniper (Juniperus communis), and Monterey cypress (Cupressus macroparpa). Thirty-six other tree and shrub species from throughout the western and southern states were analyzed for ICA (Gardner et al., 1998a; Gardner and James, 1999; Table 51.2). Similar to Utah juniper (J. osteosperma), the bark from western juniper (J. occidentalis) contains high concentrations of agathic acid and imbricatoloic acid with very little ICA. hDQj0&1>\G2AH3pv4 Zb9\:LUvyNoQf@$kS@+z[h8I5vzShgf;hml=MAe(!9{ZG,H)pqkFL ( e%"?tf^w The Project was originally started by Dr. Tony Knight in 2001. The maturetrees have a yellow to orange-red bark in broad to very broad plates with black crevices.

46.6; James etal., 1994; Gardner etal., 1994, 1997). Recently, Utah juniper bark, rich in agathic acid, was demonstrated to induce abortion in later-term pregnant cattle thus implicating agathic acid as an abortifacient component of PNs (Gardner etal., 2010). administration of ICA induced abortions in a dose-dependent manner with the higher doses inducing abortion in less time. The rumen microbes rapidly hydrolyze acetyl- and succinyl-ICA to ICA, the direct abortifacient. The resin has been chewed as a gum. Kip E. Panter, Dale R. Gardner, in Reproductive and Developmental Toxicology, 2011. Older trees have a bark of cinnamon brown to yellow, hence the name yellow pine. A reliable method to measure presence and quantity of the toxic factor in needles of ponderosa pine (Pinus ponderosa Laws.) This gives its toxic and abortifacient effects. By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. Monterey cypress is known to cause abortions in cattle in New Zealand and southern Australia and contained ICA levels of 0.89 to 1.24%. James, L. F.; Panter, K. E.; Stegelmeier, B. L.; Molyneux, R. J. Abortions are generally characterized by weak uterine contractions, incomplete cervical dilation, dystocia, birth of weak but viable calves, agalactia, and retained fetal membranes (Gardner etal., 1999). Recently, Utah juniper bark, rich in agathic acid, was demonstrated to induce abortion in later term pregnant cattle thus implicating agathic acid as an abortifacient component of pine needles (Gardner et al., 2010). Calves born after 260 days gestation have a good prognosis for survival if given colostrum and supplemented for a few days until lactation in the dam improves.

The seed can be crushed into a meal and used in making bread etc. United States Department of Agriculture (USDA), Agriculture Information Bulletin Number 415. It is extensively harvested for lumber. Provide supplemental feed when the weather is cold and/or snow covers dormant forage. The Ponderosa Pine is usuallylocated in the foothills from 7000 - 8000ft in elevation and can grow to over 250 feet tall. Similar to Utah juniper (Juniperus osteosperma), the bark from western juniper (Juniperus occidentalis) contains high concentrations of agathic acid and imbricatoloic acid with very little ICA. Acetyl and succinyl ICA derivatives, naturally present in PNs, were also abortifacient when administered orally (Gardner etal., 1996). Abortions have been associated with grazing of green needles from trees, needles from slash piles following lumber activity, and dead, dry needles from the ground.

The Agricultural Research Service of the U.S. Department of Agriculture says the needles of the ponderosa pine, Pinus ponderosa, contain isocupressic acid, which can induce abortions during the first trimester of pregnancy in cattle. PreventionKeep pregnant cows away from pine trees and fallen needles or slash piles, especially during the third trimester. Acetyl and succinyl ICA derivatives, naturally present in PN, were also abortifacient when administered orally (Gardner et al., 1996). The yew, Taxus baccata, is an evergreen conifer that is similar to pine trees. Native Americans drink pine needle tea, which allegedly has curative properties and is believed to cure scurvy. Terata have not been linked to cows ingesting Pinus contorta during pregnancy. The inner bark can be eaten raw or cooked and it is best harvested in the spring. Similar labdane resin acids are present in broom snakeweed, but the putative abortifacient and toxic components have not been fully elucidated. Both the dry and green needles from the ponderosa pine tree can cause abortion in cows. 2022 - Guide to Poisonous Plants | The information contained herein is provided as a public service with the understanding that Colorado State University makes no warranties, either expressed or implied, concerning the accuracy, completeness, reliability, or suitability of the information.

Lodgepole pine (P. contorta), common juniper (Juniperus communis), and Monterey cypress (Cupressus macrocarpa) also contain isocupressic acid and may also cause abortions when eaten by cattle. Isocupressic acid (ICA), the abortifacient compound in ponderosa pine needles and two ICA derivatives, succinyl and acetyl ICA. Lodgepole pine (Pinus contorta) and juniper (Juniperus communis) also contain isocupressic acid and causes abortions in cattle (Gardner etal., 1998). Isocupressic acid (ICA), a labdane resin acid, and two ICA derivatives were identified as the abortifacient toxins (James et al., 1994; Gardner et al., 1994, 1997; Figure 51.6).

Pregnant cows consuming ponderosa pine (Pinus ponderosa), in addition to abortion, can give birth to small and sickly calves (James etal., 1994b; Burrows and Tyrl, 2013). A study has shown that the rumen flora and fauna are important in metabolizing labdane acid compounds, and variations in rumen metabolic activity could explain variations in the susceptibility of cows (Welch etal., 2012). Nor does Colorado State University warrant that the use of this information is free of any claims of copyright infringement. Two varieties of ponderosa pine have been identified, var.

After making a selection, click one of the export format buttons. The toxin that causes abortion is isocupressic acid. From: Encyclopedia of Biodiversity (Second Edition), 2001, Kip E. Panter, Bryan L. Stegelmeier, in Veterinary Toxicology (Third Edition), 2018. Most cow losses in the field are associated with difficult parturition or post-abortion toxemia due to retained fetal membranes. The amount of items that will be exported is indicated in the bubble next to export format. A vanillaflavoringis obtained as a by-product of other resins that are released from the pulpwood. Other related labdane acids (agathic acid, imbricatoloic acid, and dihydroagathic acid) that are found in ponderosa pine needles at low levels may also contain abortifacient properties based on their similar chemical structure to ICA. A derivative of aniline, a compound derived from the yew tree, is used to make paclitaxel, a drug used to treat liver and urinary tract infections, rheumatism and cancer. Current research indicates that the concentration of labdane acids in ponderosa pine needles and western juniper bark is not uniform throughout the same tree, the concentrations can vary from location to location, and there is evidence for seasonal fluctuations as well (Cook etal., 2010, Welch etal., 2013a 2015). The abortions generally occur in the last trimester of pregnancy in the late fall, winter, or early spring. They can be eaten raw or cooked. SEINet - http://swbiodiversity.org/seinet/index.php infusion with ICA revealed that serum ICA disappearance is rapid, as only residual concentrations of ICA were detected (Gardner etal., 1999). Not all pine varieties are edible, however; the ponderosa pine and several others varieties of pine trees can cause illness and death in cattle and other animals. Not all pine varieties are edible, however; the ponderosa pine and several others varieties of pine trees can cause illness and death in cattle and other animals.One evergreen conifer, the yew, contains a toxic substance that is potentially fatal if ingested by humans. The toxin in ponderosa pine that induces abortion in cattle is the labdane resin acid isocupressic acid (12) (ICA; Gardner etal., 1994). If the abortion is near-term, the calves may survive but will be weak. Learn which plants thrive in your Hardiness Zone with our new interactive map! FIGURE 51.6.

Most cow losses in the field are associated with difficult parturition or postabortion toxemia because of retained fetal membranes. Large amounts of evergreen teas can be toxic. Dams are frequently dull and depressed, with weak uterine contractions, incomplete cervical dilation, retained placenta and frequent post-partum metritis (Cheeke, 1998). PN consumption increases during cold weather, with increased snow depth, and when other forage is limited (Pfister et al., 1998; Cook et al., 2010). While we believe these abietane-type resin acids may contribute to the occasional toxicoses reported in the field, we do not believe they contribute to the abortions. Cattle are easily averted to green PN using an emetic (lithium chloride) paired with PN consumption, but these aversions may be extinguished if cattle are offered dry needles intermingled with dormant grasses. The Australian pine is also called the Norfolk pine, house pine, and Norfolk Island pine. Isocupressic acid (ICA) is the abortifacient principle in Ponderosa and lodgepole pines, as well as in common juniper.19 It is contained in green or dry needles, bark, and branch tips. endstream endobj 73 0 obj <>stream Ponderosa pine needles (PNs) induce abortion in cattle and bison when consumed during the last trimester of gestation (James etal., 1989; Short etal., 1992; Panter etal., 1992a).

The primary toxicological effect of ponderosa pine needles in cattle is premature parturition and associated complications, such as retained fetal membranes, metritis, and occasional overt toxicosis and death (Gardner etal., 1999). ponderosa and var. Cattle are easily averted to green PNs using an emetic (lithium chloride) paired with PNs consumption, but these aversions may be extinguished if cattle are offered dry needles intermingled with dormant grasses (Pfister, 2000). Both the dry and green needles contain isocupressic acid. hAo0\ $JXYFSP%qZmZ]$' @# The mechanism of pine needle abortion involves a profound constriction of the caruncular arterial bed.21 Furthermore, pine needle extracts and plasma from fed cows increased uterine arterial tone in vitro.

Eating any part of the yew tree can result in abdominal cramping, dizziness, dry mouth, rashes and discolored skin. radiata).[3]. These animals generally require treatment. Figure46.6. administration of ICA induced abortions in a dose-dependent manner with the higher doses inducing abortion in a shorter period of time. Induced abortions generally occur in late fall to early spring, during the last trimester of pregnancy. However, the acetyl and succinyl ICA derivatives were not active when administered i.v., suggesting that intraruminal hydrolysis to ICA is important and inclusion of these two compounds in the total resin acid analysis is essential when evaluating relative risk of PN populations to induce abortions as both compounds are hydrolyzed in the rumen to ICA (Gardner etal., 1999). Metabolism occurred in the cystolic fraction of the liver homogenate and not in the microsomal fraction. No toxicity has been demonstrated from ICA or ICA derivatives; however, the abietane-type resin acids present in PNs, and found in high concentrations in the new growth tips, were shown to be toxic and abortifacient at high doses when administered orally to cattle, and toxic in goats and hamsters, causing nephrosis, edema of the central nervous system, myonecrosis, and gastroenteritis (Stegelmeier etal., 1996). Serum samples taken from cows 15min after i.v. This isocupressic-acid-induced vasoconstriction can lead to a 50% reduction in the blood flow reaching the fetal circulation and causes fetal stress, leading to the induction of premature parturition or abortion (Cheeke, 1998; Burrows and Tyrl, 2001).
