Abstracts: The effects of diazepam or midazolam on the dose of propofol required to induce anaesthesia in cats

OBJECTIVES: Assess effects of benzodiazepine administration on the propofol dose required to induce anaesthesia in healthy cats, investigate differences between midazolam and diazepam, and determine an optimal benzodiazepine dose for co-induction.

STUDY DESIGN: Prospective, randomised, blinded, placebo-controlled clinical trial.

ANIMALS: Ninety client-owned cats (ASA I and II) with a median (interquartile range) body mass of 4.0 (3.4-4.9) kg.

METHODS: All . . . → Read More: Abstracts: The effects of diazepam or midazolam on the dose of propofol required to induce anaesthesia in cats

Fatal feeding the cause of mass deaths?

Saiga tatarica.A vet from London’s Royal Veterinary College believes overeating could be the reason why Kazakhstan’s critically endangered saiga antelope (Saiga tatarica) population has suffered its second mass die-off in a row.

At a critical disease workshop held recently in Kazakhstan’s capital Astana, Richard Kock rejected the original diagnosis of pasteurellosis being the cause of death, and instead concluded the animals’ own hunger and thirst post calving, and a desire to feed on rich, moisture- laden pasture, was more likely to blame.

Both the 2010 and 2011 die-offs occurred during May, and primarily involved female saiga and their offspring. An area in the region’s Zhanibek location, long recognised as principal habitat for the Ural saiga population due to its having several low lying areas of rich pasture, was the site of both mass mortalities. However a herd of approximately 4000 animals that pastured elsewhere after calving this year, remained healthy and unaffected.

“I’m not convinced after examining the evidence that the cause for this mass die-off was pasteurellosis, or any other primary bacterial or viral transmissable contagious disease for that matter. The epidemiology doesn’t fit well. I suspect this is a die-off associated with the specific location, and pasture conditions at the time,” Kock said.
