Abstract: O trabalho teve como objetivo avaliar a eficiência de insensibiliza o de bovinos abatidos no Pantanal Sul-Mato-Grossense e a influência do transporte fluvial e rodoviário na ocorrência de les es em carca as, assim como a quantifica o em meia-carca a direita e esquerda e no quarto dianteiro e traseiro e o tamanho das les es. Observou-se que os bovinos abatidos no mesmo dia e os animais abatidos com idades mais avan adas obtiveram os maiores números de disparos. Constatou-se que, do total de 106 carca as avaliadas, 87 (82,0%) tiveram uma ou mais les es, totalizando 136 les es, que resultaram na remo o de 60,133 kg de carne, com média geral de 0,567 kg por animal ou 0,691 kg por animal considerando-se apenas os animais com les es. A freqüência de les es em carca as de bovinos entre os tratamentos avaliados mostrou diferen a significativa. As meias-carca as direita de todos os animais em todos os tratamentos obtiveram as propor es maiores de incidência de les es. N o houve diferen a significativa quanto à quantifica o de les es nas carca as entre os tratamentos. Verificou-se que houve diferen a significativa nas médias do tamanho das les es entre os tratamentos. A falta de manuten o da pistola pneumática de dardo cativo proporciona maior número de disparos. Palavras-chaveS: Contus o em carca as, pistola pneumática. This study aimed to assess the efficiency of stunning of beef cattle slaughtered in the Pantanal of Mato Grosso do Sul state and the influence of road and fluvial transport on carcass bruising, the quantification of bruises on the right and left half carcasses and the forequarter and the hindquarter, as well as the size of bruises. The cattle slaughtered on the same day and the older cattle had the highest number of shots. From a total of 106 carcasses assessed, 87 (82.0%) had one or more bruises, totaling 136 bruises, which resulted in the removal of 60.133 kg meat, with a general mean of 0.567 kg by animal or 0.691 kg by animal, considering only the animals that had bruises. There was a significant difference in terms of frequency of carcass bruising among the treatments. The right half carcasses of all animals in all treatments had the highest proportions of bruising incidence. There was no significant difference in the means of size of bruises among the treatments. The lack of maintenance of the pneumatic powered stunner caused the highest number of shots. Key words: Carcass bruising, pneumatic powered stunner.

Abstract: purpose: to determine whether rocuronium would provide safe, short-term immobilization in podocnemis expansa. methods: twenty p. expansa, weighing on average 1.59 ± 0.28 kg, were subjected to two protocols: g1 0.25 mg/kg im of rocuronium and 0.07 mg/kg im of neostigmine, while g2 received 0.50 mg/kg im of rocuronium and 0.07 mg/kg im of neostigmine. the drugs were applied, respectively, in the left and right thoracic members. assessments were made of the anesthetic parameters of respiratory frequency, heartbeat, righting reflex, cloacal relaxation, palpebral and pupilar reflexes, easy handling, muscle relaxation, locomotion, response to pain stimuli in the right thoracic members, pelvic members and tail, ambient humidity and temperature. results: they were not found statistical differences between the dosages for the majority of the assessments. g1 was as efficient as g2. a consistent neuromuscular blockade effect was recorded 12 ± 4.21 minutes in g1 and g2. all the animals were recovered in 150 minutes. conclusions: administration of rocuronium at dose of 0.25 to 0.5 mg/kg im is a safe and effective adjunct to clinical proceedings or pre-anesthetics in p. expansa. because rocuronium does not provide any analgesic or sedative effects, the duration of neuromuscular blockade without anesthesia should be minimized to avoid undue stress.
