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:
In this Research Communication we investigate the motivations of Brazilian dairy farmers to adopt automated behaviour recording and analysis systems (ABRS) and their attitudes towards the alerts that are issued. Thirty-eight farmers participated in the study distributed into two groups, ABRS users (USERS, n = 16) and non-users (NON-USERS, n = 22). In the USERS group 16 farmers accepted being interviewed, answering a semi-structured interview conducted by telephone, and the answers were transcribed and codified. In the NON-USERS group, 22 farmers answered an online questionnaire. Descriptive analysis was applied to coded answers. Most farmers were young individuals under 40 years of age, with undergraduate or graduate degrees and having recently started their productive activities, after a family succession process. Herd size varied with an overall average of approximately 100 cows. Oestrus detection and cow's health monitoring were the main reasons given to invest in this technology, and cost was the most important factor that prevented farmers from purchasing ABRS. All farmers in USERS affirmed that they observed the target cows after receiving a health or an oestrus alert. Farmers believed that they were able to intervene in the evolution of the animals' health status, as the alerts gave a window of three to four days before the onset of clinical signs of diseases, anticipating the start of the treatment.The alerts issued by the monitoring systems helped farmers to reduce the number of cows to be observed and to identify pre-clinically sick and oestrous animals more easily. Difficulties in illness detection and lack of definite protocols impaired the decision making process and early treatment, albeit farmers believed ABRS improved the farm's routine and reproductive rates MenosAbstract:
