| ABSTRACT: In Eastern Uruguay there has been a significant increase of seneciosis in grazing livestock with most affected localities related to counties neighboring the Brazilian border. A survey in 28 farms associated with poisoning outbreaks in grazing cattle in Eastern Uruguay was carried out. Fifty populations of Senecio plants were collected for alkaloid analysis and species identification. Four species were identified: S. oxyphyllus DC, S. madagascariensis Poir, S. brasiliensis (Spreng.) Less., and S. selloi DC. Alkaloids were identified by a combination of GC-MS and HPLC-MS analysis and included: retrorsine in S. oxyphyllus; retrorsine, usaramine, and senecivernine/senecionine in S. selloi; retrorsine, senecivernine/senecionine, integerrimine, and... |

| Dogs and cats are the animals that owners most frequently seek assistance for potential poisonings, and these species are frequently involved with toxicoses due to ingestion of poisonous food. Feeding human foodstuff to pets may prove itself dangerous for their health, similarly to what is observed in Allium species toxicosis. Allium species toxicosis is reported worldwide in several animal species, and the toxic principles present in them causes the transformation of hemoglobin into methemoglobin, consequently resulting in hemolytic anemia with Heinz body formation. The aim of this review is to analyze the clinicopathologic aspects and therapeutic approach of this serious toxicosis of dogs and cats in order to give knowledge to veterinarians about Allium... |

| Fifteen mature crossbred sheep were fed different daily amounts (2.5-35g kg-1 bw) of the fresh green leaves of Ateleia glazioviana for different periods of time (1-24 days). One sheep was not fed the plant and served as a control. All 16 sheep were euthanatized at different stages of the experiment, necropsied, and several organs, including heart and brain were evaluated histologically. Samples of five brain regions from three affected sheep were evaluated by electron microscopy. Clinical signs observed in three sheep included depression, anorexia, general weakness, staggering gait and prolonged recumbency. One sheep had signs of congestive heart failure. Necropsy findings included subcutaneous dependent edema and edema of the body cavities in two sheep... |

| Palicourea aeneofusca contains sodium monofluoroacetate, which causes sudden death in ruminants when administered at doses of approximately 0.6g kg-1 of body weight (g kg-1). In this experiment two groups of 6 goats were used to determine the possibility to induce conditioned food aversion to P. aeneofusca. In group 1, 0.35g kg-1 of green leaves of the plant were given to six goats on days 1, 5, 10, 20, 30, 60, and 90 of the experiment. On the first day, all of the goats ingested the full amount of the plant and were treated immediately with 175mg kg-1 of lithium chloride (LiCl) through a ruminal tube. On day 5, only two goats ingested the plant, and they were treated with the same dose of LiCl. On days 10, 20, 30, 60, and 90, none of the goats ingested... |

| Ipomoea carnea is a toxic plant often ingested by livestock in Brazil. Three experiments were conducted to determine if conditioned food aversion was effective in reducing goats' consumption of I. carnea. In the first experiment, 10 mildly intoxicated goats that had been eating I. carnea were averted using LiCl (175 to 200mg kg-1 body weight). These intoxicated goats did not develop an aversion to I. carnea, demonstrating that the technique is not effective in goats that are already accustomed to consuming the plant. In the second experiment, 14 naïve goats were placed in a pasture with I. carnea, and averted after they ingested the plant. In this group the aversion persisted until the end of the experiment, 2 years and 8 months after the initial aversion.... |

| In almost all types of vegetation there are species that can cause toxicity to livestock that consumes. The poisoning caused problems in many different animals can affect reproduction, weight gain, and even death. These problems are causing economic losses in the livestock industry it is necessary to quantify but very difficult to achieve it. In Sonora, has been diagnosed rangeland of overgrazing, which manifests itself in a deterioration that diminishes the species desirable and undesirable increases, among these plants are toxic. We have identified 184 species that are toxic and within them there are 59 species that consume livestock and cause problems. For the foregoing are raised by this study, in order to try to estimate the economic impact that cause... |

| Ipomoea carnea is a toxic plant that grazing goats and cattle may learn to ingest with repeated exposure. The objective of this study was to evaluate the feeding preferences of experienced and non-experienced (naïve) goats and sheep for I. carnea.The study used 3 groups of 5 goats (Group 1, experienced that were previously poisoned by the plant; group 2, naïve; Group 3, experienced eaters, composed of animals adapted to eat the fresh plant) and 2 groups of sheep (group 4, experienced that were previously poisoned by the plant; and group 5, naïve). For the test, the animals were placed daily for 10 minutes and 4 days in a rectangular stall (5x7m) with 4 feeders, each with 200g of a different food (Ipomoea carnea, commercial concentrate food, recently... |

| Weeds in pastures can intoxicate animals, and Arrabidaea bilabiata is the most important species for herbivores in floodplain areas in the Amazon Basin. Genetic diversity studies in natural populations may contribute to the better understanding of the range of toxicity and the genetic variability organization in this species. The objective of this study was to assess the variability and genetic structure in six populations of A. bilabiata sampled in floodplain areas in three municipalities of the Amazonas State, from the AFLP markers analysis. AFLP markers were efficient to characterize the genetic variability of the 65 individuals analyzed. From four combinations of oligonucleotides, a total of 309 AFLP fragments was obtained, where 304 (98.38%) were... |
