摘要:

Trials were conducted to test the ability of yohimbine, 4-aminopyridine and doxapram given by intravenous injection to antagonise xylazine sedation in red deer (Cervus elaphus). Yohimbine produced the best and most consistent result. The mean time taken for 34 animals to stand spontaneously after receiving yohimbine (0.2 to 0.25 mg/kg) was 2 minutes 25 seconds and this occurred, on average, 33 minutes after the initial doze of xylazine. Control deer took 67 and 104 minutes on average to stand after receiving intravenous (0.64–0.96 mg/kg) and intramuscular (1.0–1.5 mg/kg) injections of xylazine respectively. Two deer which received an overdose of xylazine (4 mg/kg) recovered 3 and 9 minutes respectively after receiving yohimbine. Two deer given a high intravenous dose of yohimbine (1.0 mg/kg) became mildly nervous and anxious, but returned to normal within an hour. 4-aminopyridine (0.3 mg/kg) alone produced some arousal from xylazine sedation (0.6–1.0 mg/kg) but was inconsistent. In combination with yohimbine (0.125 mg/kg) it produced rapid recovery in two deer but caused convulsions in two other deer.

摘要:

Niclosamide and cupric acetoarsenite were both effective in removing tapeworm (Moniezia expansa) from unweaned lambs. In four trials there was no significant liveweight gain in niclosamide-drenched, compared with undrenched, animals.Post-mortemexamination for tapeworm showed that although one lamb contained 200 ml (bulk volume) of strobila, 50% of 49 infected animals contained 50 ml or less. The greatest number of scoleces in one animal was 41, and 65% of lambs contained four or fewer.M. expansais not indicated as a cause of diarrhoea in lambs.

摘要:

An improved facility for the treatment of footrot is described. It consists of a continuous flow system designed for the inspection and treatment of large numbers of stock. It is considered that such a system is an essential prerequisite before embarking on a treatment programme.
