Resumo: No Brasil, estima-se que as intoxicações por plantas tóxicas que contém monofluoroacetato de sódio (MFA) causam a morte de aproximadamente 500.000 bovinosao ano. A inoculação ruminal de bactérias que degradam MFA tem sido proposta como uma forma de prevenir a intoxicação. O presente trabalho teve como objetivo avaliar, em caprinos, a resistência ao MFA presente em Amorimia septentrionalis, induzida por inoculação ruminal das bactérias Pigmentiphaga kullae e Ancylobacter dichloromethanicus. Doze caprinos, que nunca tiveram contato prévio com plantas que contêm MFA, foram divididos em dois grupos, com seis animais cada. No grupo 1, 60 mL de uma mistura das duas bactérias foi inoculada, diariamente, durante 10 dias em cada caprino. No grupo 2, os caprinos não receberam as bactérias. A partir do 10º dia de inoculação, A. septentrionalis foi administrada, diariamente, na dose de 5g/kg de peso vivo, sendo interrompida em cada animal após a observação dos primeiros sinais clínicos da intoxicação. Os caprinos do grupo 1 apresentaram sinais clínicos 5,83±2,56 dias após a administração da planta o que diferiu significativamente (p=0,037) dos caprinos do grupo 2, que apresentaram sinais clínicos aos 2,67±0,52 dias. A quantidade de planta ingerida pelos caprinos inoculados (28,83±12,97g/kg) e os não inoculados (12,03±3,65g/kg) para desencadear os sinais clínicos foi, também, estatisticamente diferente entre os grupos (p=0,025). Conclui-se que a administração intraruminal de Pigmentiphaga kullae e Ancylobacter dichloromethanicus induz resistência à intoxicação por plantas que contêm MFA. [Resistance to poisoning by Amorimia septentrionalis in goats induced by ruminal inoculation of the bacteria Pigmentiphaga kullae and Ancylobacter dichloromethanicus]. Abstract: In Brazil is estimated that poisoning of livestock by sodium monofluoroacetate (MFA) containing plants causes the death of about 500.000 cattle per year. The ruminal inoculation of bacteria that degrade MFA has been proposed as a way to prevent the poisoning. This study aimed to evaluate in goats resistance to the MFA-containing plant Amorimia septentrionalis induced by ruminal inoculation of the bacteria Pigmentiphaga kullae and Ancylobacter dichloromethanicus. Twelve goats, without previous contact with MFA-containing plants, were divided into two groups of six animals each. In group 1, 60ml of a mixture of the two bacteria was inoculated every day for 10 days into each goat. In group 2, the goats did not receive the bacteria. At the 10th day of inoculation, A. septentrionalis began to be administered daily at a dose of 5g/kg body weight to both groups. The administration was interrupted in each goat after first clinical signs of poisoning were observed.. The goats of group 1 showed clinical signs 5.83±2.56 days after the administration of the plant, what differed significantly (p=0.037) from goats of group 2, that showed clinical signs 2.67±0 52 days after the beginning of ingestion. The amount of A. septentrionalis ingested by inoculated goats (28.83±12.97g/kg) to cause clinical sings was significantly greater (p=0.025) than the amount ingested by the non-inoculated (12.03±3.65) goats to cause clinical signs and was also statistically different between the groups. We concluded that the intraruminal administration of Pigmentiphaga kullae and Ancylobacter dichloromethanicus increases the resistance to poisoning by MFA-containing plants.

According to some studies, the use of forest biomass for the generation of electric power and/or heat would result in a significant reduction in the emission of greenhouse gases. This would happen even in the case of soils substitution that currently have an agricultural use although its implementation would require more studies on the environmental impact that they could have in each particular case. In this study, the potential of electric power production is evaluated with several species of Eucalyptus planted in short rotation forestry systems. Three species were evaluated: E. benthamii, E. dunnii and E. grandis in four spacings: 3×1.5 m, 3×1 m, 3×0.75 m, 3×0.5 m, in two sites in the northern and western areas of Uruguay during a period of 76 and 75 months, respectively. During this period, the following parameters were evaluated: higher heating value, wood density, energy density and energy yield per hectare and per year. The results obtained show that the heating value changes slightly with the planting density and age. The average of higher heating values were 19,787 versus 19,454 J g-1 and 19,867 versus 9909 J g-1for the planting densities of 2220 versus 6660 trees ha-1 at Paysandú and Tacuarembó, respectively, at 76 months. Higher heating value increased from 19,665 to 19,745 J g-1 at 18 months to 19,740 and 19,914 J g-1 at 76 months for Paysandú and Tacuarembó, respectively. The wood density, depending on the site, is affected by age, species and planting density. On average, wood density increased (only at Paysandú) from 0.405 g cm-3 at age 18 months to 0.497 g cm-3 at age 76 months. There is a negative relationship between the heating value and the wood density. The energy yield is basically explained by the production of biomass. At Tacuarembó, a stronger relationship between energy production and planting density is obtained (1012 vs. 636 MW ha-1 for 6660 and 2220 trees ha-1, respectively) compared to the Paysandú site (1093 vs. 912 MW ha-1 for 6660 and 2220 trees ha-1, respectively).
