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.

ABSTRACT.
Agricultural systems in Uruguay exhibit a high frequency of soybean in crop rotations. This could adversely affect soil organic carbon (SOC) storage in the long term. The introduction of winter annual cover crops (CC) in these systems may improve SOC balance as well as reduce the impact of rainfall on soil erosion rates. The objective of this study was to evaluate the impact of the inclusion of CC on SOC storage and soil physical properties under continuous soybean (Glycine max [L.] Merr) cropping systems. A ? eld experiment was established in 2003 in a vertic Argiudoll. A split plot design was used with CC and non CC as whole plot arranged in four randomized complete blocks. Cover crops were: oats (Avena sativa L)., annual ryegrass (Lolium multi? orum L.). Two termination dates comprised split plots: 60 or 30 days before soybean planting. Mean annual forage production over eight years was higher (P ? 0.05) in oats compared to annual ryegrass for both termination dates. The inclusion of CC increased SOC concentration at the 0-7.5 cm depth, and at the 7.5-15 cm depth in the annual ryegrass treatment. Oats and annual ryegrass had 60 and 80 % more particulate organic carbon (POC) concentrations at the 0-7.5 cm, respectively than no cover crop treatment. No signi? cant differences among treatments were observed for mineral associated organic C-MAOM at any depth. Nitrogen mineralization potential under ryegrass had a three-fold increase compared to the no cover crop treatment. Both CC treatments showed a higher (P ? 0.05) percentage of macropores compared to the no cover crop treatment. In most of the years soybean grain yield was not affected by cover crops treatments. However, late termination dates often reduced soybean yields. The inclusion of CC in high frequency soybean cropping systems may enhance soil C storage, and improve related soil physical properties.
