Single and multiple-dose pharmacokinetics of meloxicam after oral administration to the rabbit (Oryctolagus cuniculus).

The nonsteroidal anti-inflammatory drug (NSAID) meloxicam is a very popular anti-inflammatory, analgesic, and antipyretic agent used in veterinary medicine. To determine the pharmacokinetics of this NSAID in rabbits following a single dose and 10-day period of dosing, eight clinically normal, 8-mo-old New Zealand white rabbits (Oryctolagus cuniculus) were administered 0.2 mg/kg meloxicam p.

Single- and multiple-dose pharmacokinetics of marbofloxacin after oral administration to rabbits.

OBJECTIVE-To determine the pharmacokinetics of marbofloxacin after oral administration every 24 hours to rabbits during a 10-day period. ANIMALS-8 healthy 9-month-old female New Zealand White rabbits. PROCEDURES-Marbofloxacin (5 mg/kg) was administered orally every 24 hours to 8 rabbits for 10 days.

West Nile virus in the Americas.

West Nile virus causes sporadic disease in the Eastern hemisphere that is often asymptomatic or mild, whereas in the Western hemisphere, West Nile virus has been associated with illness and profound mortality in many avian species. West Nile virus might have been transported to North America by an infected mosquito or the virus could have entered within a vertebrate host like a bird. Although the most important method of West Nile virus transmission is by Culex species mosquitoes, additional modes of transmission have been identified.

Avian reproductive anatomy, physiology and endocrinology.

Although many environmental cues influence reproductive activity, the seasonal breeder responds most strongly to long day length. THE MALE BIRD: Testicular interstitial cells secrete testosterone, which influences reproductive behavior such as territorial aggression and song. Other changes observed in seasonal breeders include testicular hypertrophy and enlargement of the ductus deferens and seminal glomus.
