Dehorning is a common practice in cattle farming. Researchers suggest that pain during dehorning can be mitigated, although there is no conclusive evidence about the best technique and the best manner of pain relief. A systematic review-meta-analysis was performed to clarify the effect of dehorning on welfare indicators (cortisol concentration or average daily gain [ADG] or vocalisation) in beef cattle up to 12 months of age. Five electronic databases were systematically searched, as well as conference proceedings and experts were contacted electronically. Pre-defined protocols were applied during all steps of the systematic review process. A random effect meta-analysis was conducted for each indicator separately with the mean of the control and treated groups. Four publications reporting 7 studies and 69 trials were included in the MA involving 287 cattle. Heterogeneity between studies was observed for cortisol (I2 = 50.5%), ADG (I2 = 70.5%), and vocalisation (I2 = 91.9%). When comparing the non-dehorned group with amputation dehorning, the cortisol concentration was lower 30 min (P < 0.0001) and 120 min (P = 0.023) after procedure (0.767 nmol/L and 0.680 nmol/L, respectively). Local anaesthesia did not show a reduction in cortisol concentration at 30 min after dehorning by amputation. Non-dehorned animals had a tendency to decrease the number of vocalisation (P = 0.081; MD = 0.929) compared with the group dehorned by amputation. These results suggest that dehorning is a painful experience and that local anaesthesia did not alleviate short-term pain following dehorning. Further investigation into pain relief is required to improve confident decision making under practical conditions. © 2019 CSIRO. MenosDehorning is a common practice in cattle farming.

ABSTRACT.
Herbaspirillum seropedicae is a nitrogen-fixing bacterium capable of using toxic compounds as a source of carbon. Bacteria with this capacity can be used to make animals resistant to plant poisoning containing monofluoroacetate (MFA), such as Amorimia septentrionalis. The aim of this study was to evaluate if H. seropedicae is efficient in the degradation of MFA present in A. septentrionalis and if the inoculation of this bacterium in goats confers protection to A. septentrionalis intoxication. Two experiments were performed: in the first experiment 12 goats were divided into 2 groups. Goats in Group 1 were orally administered a solution containing the H. seropedicae bacterium for 10 days. From day 10 onwards, they received a daily dose of 5g/kg of A. septentrionalis with the bacteriauntil clinical signs of intoxication were observed. Group 2 goats received only the plant at the same dose, also until the observation of clinical signs of intoxication. The amount of MFA found in A. septentrionalis used in the experiment with goats was 1.6±0.058?g/mg. The total plant dose ingested by all goats in Group 1 was 80.83±12.81g/kg (129.33±20.50mg/kg MFA), which were significantly greater (p<0.05) than those of Group 2 goats (39.16±19.08g/kg plant and 62.66±30.53mg/kg MFA). Group 1 goats took an average of 16.16±2.56 days to develop clinical signs of intoxication, significantly longer (p=0.0012) than Group 2 goats (7.83±3.81 days). Two Group 2 goats died on the same day that they developed clinical signs of intoxication. At necropsy of these two animals, no significant changes were observed. In the second experiment, samples of A. septentrionalis were sprayed with a solution containing H. seropedicae. Before and eight days after spraying, the samples were pressed and dried for quantitation of MFA. The amount of MFA present in samples of A. septentrionalis 8 days after spraying with H. seropedicae was significantly lower (p=0.017) than that found prior to spraying. It can be concluded that administration of H. seropedicae in goats is capable of causing greater resistance to A. septentrionalis intoxication, and spraying the plant with this bacterium significantly reduces the amount of MFA in the plant.

RESUMO.
Herbaspirillum seropedicae é uma bactéria fixadora de nitrogênio, capaz de utilizar compostos tóxicos como fonte de carbono. Bactérias com essa capacidade podem ser utilizadas para tornar os animais resistentes à intoxicação por plantas que contém monofluoroacetato (MFA), como Amorimia septentrionalis. O objetivo do presente estudo é avaliar se H. seropedicae é eficiente na degradação do MFA presente em A. septentrionalis e se a inoculação dessa bactéria, em caprinos, confere proteção à intoxicação por A. septentrionalis. Foram realizados dois experimentos: no primeiro experimento foram utilizados 12 caprinos, divididos em dois grupos. Os caprinos do Grupo 1 receberam diariamente, oralmente, uma solução contendo a bactéria H. seropedicae durante 10 dias. A partir do décimo dia passaram a receber, diariamente, além da solução com a bactéria 5g/kg de A. septentrionalis até a observação de sinal clínico de intoxicação. Os caprinos do Grupo 2 receberam apenas a planta na mesma dose, também até que a observação de sinais clínicos de intoxicação. A quantidade de MFA encontrada em A. septentrionalis utilizada no experimento com caprinos foi de 1,6± 0,058µg/mg de planta em média. A dose total de planta ingerida por todos os caprinos do Grupo 1 foi de 80,83±12,81g/kg (129,33±20,50mg/kg de MFA), valores significativamente maiores (p<0,05) do que os dos caprinos do Grupo 2 (39,16±19,08g/kg de planta e 62,66± 30,53mg/Kg de MFA). Os caprinos do Grupo 1 demoraram em média 16,16 ±2,56 dias para desenvolver sinais clínicos da intoxicação, período significativamente maior (p=0,0012) que os caprinos do Grupo 2 (7,83±3,81dias). Dois caprinos do Grupo 2 morreram no mesmo dia que desenvolveram sinais clínicos da intoxicação. Na necropsia desses dois animais não foram observadas alterações significativas. No segundo experimento, amostras de A. septentrionalis foram pulverizadas com uma solução contendo a bactéria H. seropedicae. Antes e oito dias após a pulverização, as amostras foram prensadas e secas para posterior quantificação do MFA. A quantidade de MFA presente nas amostras de A. septentrionalis oito dias após a pulverização com H. seropedicae foi significativamente menor (p=0,017) do que a encontrada antes da pulverização. Pode-se concluir que a administração de H. seropedicae em caprinos é capaz de causar uma maior resistência à intoxicação por A. septentrionalis, e a pulverização da planta com esta bactéria reduz significativamente a quantidade de MFA na planta.
