All cases where sedation is needed, e.g. during transport, partus, hoof treatment, small operations (e.g. de-horning), and as a pre-anesthetic for larger operations (caesarean sections).
Xylazine has sedative, analgesic and muscle-relaxing properties.
Cattle: for intramuscular administration.
Dose 1: 0.25 ml per 100 kg body weight; sedation, small operations.
Dose 2: 0.5 ml per 100 kg body weight; small operations. Animals usually remain standing.
Dose 3: 1 ml per 100 kg body weight; larger operations. Animals lie down.
Dose 4: 1.5 ml per 100 kg body weight; very extensive operations.
Animals have to fast for a couple of hours before administration.
Horses : 4 ml per 100 kg body weight for intravenous administration, or 10 ml per 100 kg body weight for intramuscular administration.
With larger operations preferably in combination with other preparations, e.g.
Intravenous 4 ml per 100 kg body weight and halothane or fluothane as intubation narcosis.
Administration during gestation or to animals with lung and/or heart diseases.
Administration to animals with pyometra, because these animals are often hypersensitive to this preparation.
Decreased heart and respiratory rate. Hyper salivation and vomiting.
For meat: 5 days. For milk: 4 days.
During application, keep the animals as quiet as possible. Alpha-adrenergic antagonists, yohimbine, idazoxan and tolazoline can be used to shorten the sedative effect.
