Effects of detomidine in young water buffalo

Following preliminary studies with detomidine hydrochloride in 10 young buffaloes (Bubalus bubalis), the effects of an intramuscular injection of 40 /ixg.kg-¹ were studied in 6 healthy buffaloes of VA to 2 years of age, weighing between 85 and 140 kg. Arterial blood pressure, central venous pressure, heart rate, electrocardiogram, electroencephalogram, respiratory rate, arterial pH, arterial and venous blood gases and rectal temperature were monitored before, and for an hour after, intramuscular injection of detomidine. Marked ataxia and sternal recumbency occurred within 10 minutes of injection, and an apparent complete recovery occurred in about 90 minutes. The electroencephalograms never demonstrated the high-voltage-low-frequency wave forms normally associated with sedation, but the animals appeared well sedated.
After injection there was marked decrease in heart rate which then tended to increase but it remained significantly (P < 0.05) below pre-injection values at 60 minutes. The mean arterial pressure increased initially, especially when electrocardiogram showed AV block, but after 15 minutes it had declined to below pre-injection values. These changes in the arterial blood pressure were, however, not statistically significant. Central venous pressure tended to increase during sedation but except at 30 minutes this increase was not statistically significant.
Rectal temperature, arterial pH, arterial carbon dioxide tension, standard bicarbonate and cranial vena caval oxygen tension did not show any significant variation. Respiratory rate and arterial oxygen tension decreased significantly.     

饲喂水牛奶及代乳粉对水牛犊牛营养代谢及生长性能的影响

为了对比水牛奶与代乳粉对水牛生长发育及营养物质代谢的影响,试验选取初生犊牛16头,根据犊牛出生顺序依次分为对照组(8头)和试验组(8头),以克服出生时对各组产生的差异。对照组饲喂水牛奶,试验组饲喂能量水平实测值为20.35 MJ/kg的代乳粉。饲养试验从水牛犊牛7日龄之后计起,持续90 d,饲养试验期间水牛犊牛自由采食精料及饲草。饲养试验结束时,即从水牛犊牛的90日龄起从饲养试验的水牛犊牛中每组选出4头开始为期8天的消化代谢试验,消化代谢的前5天为适应期,后3天为粪尿样采集期。试验结果表明,在试验期间,两组犊牛的平均日增重分别为0.51 kg/d、0.34 kg/d,水牛奶组与代乳粉组间差异极显著(P0.01),水牛奶组的总能和总氮摄入也显著高于代乳粉组(P0.05);水牛奶组和代乳粉组犊牛对饲料能量的利用效率差异均不显著(P0.05);水牛奶组对氮的利用效率高于代乳粉组;水牛奶组的90日龄体重、胸围、腹围、胸宽和胸深显著高于代乳粉组(P0.05)。由此可知,提高饲粮的能量水平有利于水牛犊牛的能量代谢、氮代谢和生长发育。     

Pasteurellosis in sheep

Pasteurellosis is an important cause of economic loss to the sheep industry. There are two distinct syndromes. The pneumonic form of the disease caused by P haemolytica biotype A occurs as pneumonia in flocks and sporadically in individual sheep. The septicaemic form, caused by P haemolytica biotype T is associated with hyper-acute disease and occurs most commonly in the autumn coinciding with the folding of hoggs on rape, turnips and improved pastures. The factors which predispose sheep to the different forms of the disease are poorly understood but recently it has been possible to reproduce pasteurella pneumonia experimentally.
