| ABSTRACT: Two outbreaks of trypanosomiasis by Trypanosoma evansi in horses in the municipality of Chaves, Marajó Island, Pará State, Brazil are reported. The first outbreak occurred in April 2011 in a farm with 147 horses; of these, 47 (31.97%) got sick, and 40 (27.21%) died. The second outbreak occurred in May 2012 and involved nine properties. Of a total of 679 horses, 209 (30.07%) got sick, and 183 (26.97%) died. The main clinical signs observed in these horses were weight loss, abdominal edema, toe dragging, and pelvic muscle atrophy. Necropsy was performed in two horses, one from each outbreak. Macroscopic alterations were not seen in the horse from the first outbreak; however, the horse from the second outbreak exhibited emaciation, pallor and... |

| 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... |

| 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.... |
