| 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... |

| ABSTRACT: Strongyloides spp. are intestinal parasites that affect several animal species. Four species of the genus have been reported in domestic cats: S. felis, S. planiceps, S.stercoralis and S. tumefaciens . Reports describing infection by these nematodes in domestic cats in Brazil are scarce. This study aimed to describe the pathological features of Strongyloides spp. parasitism in two cats in the Amazon region, state of Pará, Brazil. During the necropsy of the two cats, numerous whitish nodules approximately 0.2cm in diameter were observed in the wall of the large intestine. The nodules were conspicuous in the colonic mucosa and exhibited a punctate aperture facing the center of the lumen. Microscopically, these nodules were formed by projections... |

| 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.... |

| Granuloma nasal ocorreu em 13 bovinos Jersey, fêmeas, com idades entre 9 meses e 3 anos, em uma propriedade de Pinhal Grande, Rio Grande do Sul. Sinais clínicos incluíam corrimento nasal seroso ou mucoso, às vezes com estrias de sangue, espirros, respiração ruidosa, dificuldade em respirar, lacrimejamento, congestão dos vasos da esclera e roçar o focinho em árvores e outros objetos. Os sinais clínicos se exacerbavam após exercício. No exame clínico de 10 bovinos, foram observados nódulos na mucosa da porção proximal da cavidade nasal. Na citologia do corrimento nasal de 9 bovinos, observaram-se eosinófilos em números diretamente proporcionais à intensidade dos sinais clínicos. Não houve alterações no hemograma. Um dos animais afetados foi sacrificado e... |

| In the Amazon region, sprouting pastures of Panicum maximum cause colic and death in horses and mules. To produce the disease two experiments were performed with growing P. maximum cv. 'Mombaça' in penned horses. In Experiment 1, at the beginning of the raining season, 10 horses were fed with recently harvested sprouting P. maximum. Two horses showed colic on the 5th and 11th day after start of the ingestion. In Experiment 2, also during the raining season, the same 10 horses used in Experiment 2 were divided into two groups of 5 horses each. Group 1 received sprouting P. maximum immediately after harvested and Group 2 received the grass 24 hours after harvested. The control group consisted of four animals which were placed in individual pens and fed with... |

| No Brasil, as plantas que contêm swainsonina compõem um grupo muito importante de plantas tóxicas, incluindo Ipomoea carnea subsp. fistulosa, Ipomoea riedelii, Ipomoea sericophyla, Ipomoea verbascoidea, Turbina cordata e Sida carpinifolia, que causam armazenamento de oligossacarídeos em caprinos e, com menor frequência, em bovinos, equinos, ovinos e cervídeos. Uma característica das plantas que contêm swainsonina é que os animais que iniciam a ingerir essas plantas desenvolvem o hábito de ingeri-las compulsivamente e, por facilitação social, induzem a outros animais da mesma espécie a ingeri-las. Os animais intoxicados apresentam pêlos arrepiados, perda de peso e sinais nervosos associados, principalmente, a lesões cerebelares e do tronco encefálico.... |
