Verbesina encelioides is a widely distributed weed in Argentina. Although it has been suspected as poisonous, there seem to be no previous reports of its toxicity in this country. Its biological activity was evaluated through an experiment in sheep. Four 5-y-old sheep, averaging 33 kg in body weight, were given a single dose of 1.0, 3.2, 5.0 or 6.3 g of(More)
The literature on Conium maculatum biochemistry and toxicology, dispersed in a large number of scientific publications, has been put together in this review. C. maculatum is a weed known almost worldwide by its toxicity to many domestic animals and to human beings. It is an Umbelliferae, characterized by long, hollow stems, reaching up to 2 m height at(More)

Aberdeen Angus (AA) and crossbred AA x Hereford 8-9 mo old heifers (560 animals) showed a typical perennial ryegrass (PRG) staggers syndrome after grazing 26 d in a 25-hectare paddock of pure Lolium perenne. Effects were observed in about 50% of the herd. When forced to move, the animals showed incoordination, weakening of the forelimbs, falling on the(More)
Individual loci of economic importance (QTL) can be detected by comparing the inheritance of a trait and the inheritance of loci with alleles readily identifiable by laboratory methods (genetic markers). Data on allele segregation at the individual level are costly and alternatives have been proposed that make use of allele frequencies among progeny, rather(More)
Six breeding rams were fed a diet containing 12 mg of zearalenone daily for eight weeks. A control group of six rams was fed a diet free of zearalenone. The weekly production of spermatozoa of both groups was measured during the period of administration of zearalenone and for six weeks after the administration of zearalenone ceased. Semen production was(More)
Researchers at Los Alamos National Laboratory (LANL) are developing a new solid-state high-voltage Marx modulator for the generation of pulsed power. The initial application of the LANL modulator is to provide power to a magnetron that requires a 46-kV, 160-A, 5-μs rectangular pulse. This modulator technology is also being developed for other applications,(More)
Vicia villosa (hairy vetch) is used as a forage source in some cattle-producing areas in Argentina. The plant had no previous reports of toxicity in this country. A herd of 33 Aberdeen Angus bulls grazed during 20 days in October on a pasture composed mainly of hairy vetch. Eight animals developed conjunctivitis, rinitis, dermatitis, loss of hair and fever.(More)
Poisoning of domestic animals happens frequently in the southeast of Buenos Aires Province (Argentina). Intoxications are produced mainly by the ingestion of plants and mycotoxins, but animals are rarely affected simultaneously by both types of agents. One herd of pigs suffered simultaneous intoxications by ergot alkaloids from Claviceps purpurea sclerotia(More)
The relationship between observed early teeth wearing in cattle and the existence of large areas where excess fluoride in underground water prevails in Argentina, but has never been studied. Average values of bone fluoride exceeding 5000 ppm and well water containing up to 10.5 ppm of this element were found in a farm (ETWF) where early teeth wearing is(More)
