RESUMO

INTRODUCTION: The aim of this study was to find an intramuscularly (IM) injectable anaesthetic combination for 8 to 14-days old piglets, that guarantees a calm induction and sufficient quality of anaesthesia without excitations with a maximum of two hours long lasting recovery. In preliminary dose finding trials, different combinations of -ketamine, azaperone and romifidine were compared. A constant dose of 0.2 mg/kg of butorphanol was added to each combination and all piglets received 0.4 mg/kg meloxicam. Subsequently a dosage algorithm for the main trial was developed. In case of insufficient analgesia, lidocaine 2% (0.25 ml) was injected intratesticular. If two piglets showed an insufficient anaesthetic induction phase, depth of anaesthesia or recovery, the next dosage in the algorithm was tried. With the combination of 3 mg/kg azaperone, 0.2 mg/kg romifidine, 15 mg/kg ketamine and 0.2 mg/kg butorphanol the requirement of a smooth anaesthesia induction, sufficient anaesthesia and a recovery without excitation was fulfilled but the recovery lasted more than 120 minutes.


INTRODUCTION: Le but de la présente étude était de mettre au point une combinaison d'anesthésiques injectables par voie intra-musculaire pour les porcelets âgés de 8 à 14 jours qui garantisse une induction calme, une qualité d'anesthésie suffisante (sans mouvement de défense durant l'intervention) et une phase de réveil dépourvue d'excitation et ne durant pas plus de deux heures. Dans le cadre d'un essai préliminaire, on a comparé, afin de définir les doses respectives, des combinaisons de kétamine, d'azapérone et de romifidine. Les résultats ont servi de base pour l'algorithme de dosage de l'essai principal. Les dosages testés étaient les suivants : 1, 2 ou 3 mg/kg d'azapérone, 10 ou 15 mg/kg de kétamine et 0.15 ou 0.2 mg/kg de romifidine. En outre, tous les animaux recevaient du méloxicam (0.4 mg/kg) et du butorphanol (0.2 mg/kg) IM. En cas d'analgésie insuffisante, de la lidocaïne 2% (0.25 ml) était appliquée en intra-testiculaire. Si deux porcelets montraient une phase d'induction, de castration ou de réveil insuffisante, on passait au dosage suivant. Avec la combinaison de 3 mg/kg d'azapérone, 0.2 mg/kg de romifidine, 15 mg/kg de kétamine et de 0.2 mg/kg de butorphanol, les exigences d'une induction calme, d'une qualité d'anesthésie suffisante et d'un réveil dépourvu d'excitation étaient remplies. Toutefois les porcelets dormaient plus de 120 minutes.

RESUMO

INTRODUCTION: In this study dose rate combinations of ketamine, azaperone and romifidine were tested in 3-4 (G3-4) and 5-6 weeks (G5-6) old piglets according to a dose rate decision tree (DRT) to provide calm anaesthesia induction, reaction-free anaesthesia for castration and smooth recovery within 2 hours. When a combination failed to meet those criteria in 2 piglets, the next dosage of the DRT was tested. In G3-4 four combinations were tested in 14 piglets with dose rates of 10-20 mg/kg ketamine, 3 mg/kg azaperone and 0.15-0.20 mg/kg romifidine IM. Induction was smooth in all piglets, but depth of anaesthesia or recovery (11 and 6 piglets) were insufficient. In G5-6 five combinations were tested in 37 piglets with dose rates of 10-20 mg/kg ketamine, 3-4 mg/kg azaperone and 0.15-0.20 mg/kg romifidine IM. Induction was smooth in all piglets but 2. Depth of anaesthesia or recovery (17 and 7 piglets, respectively) were insufficient. In the present study with 3-4 and 5-6 weeks old piglets, acceptable quality of anaesthesia could not be achieved despite using high drug dose rates.


INTRODUCTION: Des combinaisons de doses de kétamine, azapérone et romifidine ont été testées sur la base d'un arbre de décision de dose afin de définir la dose qui assurait, chez des porcelets de 3-4 (G3-4) et de 5-6 (G5-6) semaines une induction tranquille, une anesthésie sans réaction lors de la castration et une phase de réveil calme, terminée en deux heures. Lorsqu'une combinaison de ces critères n'était pas obtenue chez 2 porcelets, on passait à la dose suivante proposée par l'arbre de décision. Dans le G3-4, 4 combinaisons avec des doses de 10-20 mg/kg de kétamine, 3 mg/kg d'azapérone et 0.15-0.20 mg/kg de romifidine IM ont été testées chez 14 porcelets. L'induction était calme chez tous les porcelets mais la profondeur de l'anesthésie ou la phase de réveil étaient insuffisantes chez 11 respectivement 6 porcelets. Dans le G5-6, 5 combinaisons avec des doses de 10-20 mg/kg de kétamine, 3-4 mg/kg d'azapérone et 0.15-0.20 mg/kg de romifidine IM ont été testées chez 37 porcelets. L'induction était calme à deux exceptions près mais la profondeur de l'anesthésie ou la phase de réveil étaient insuffisantes chez 17 respectivement 7 porcelets. Lors de la présente étude, il n'a pas été possible, malgré l'utilisation de doses élevées, d'obtenir chez des porcelets de 3-4 respectivement de 5-6 semaines une qualité d'anesthésie acceptable.

RESUMO

At the end of the national eradication program for Enzootic Pneumonia (EP) and Porcine Actinobacillosis (APP) in Switzerland (2003), A. pleuropneumoniae serotype 2 is considered to have been eradicated. There is no current information about the distribution of the other serotypes available. The ApxIV ELISA detects antibodies against all serotypes of A. pleuropneumoniae, without cross-reaction with other bacterial species. The aim of this study was to achieve actual data concerning the seroprevalence of A. pleuropneumoniae in breeding-herds and to validate the ApxIV ELISA under field conditions, especially for the diagnosis of latently infected breeding-herds without clinical signs, and to achieve more information about the role of herd book farms for the spread of the infectious agent. A total of 2068 serum samples from 96 pig herds in Switzerland were examinated. Over half of the examinated herd book farms showed positive results in this ELISA. 93% of the breeding herds were positive. On single animal level sensitivity was 96% and specifity 100%. Herd sensitivity ranged between 67% and 99%. Herd specifity was 100%. The results show that the ApxIV ELISA is a valuable tool for the detection of latently infected herds.
