Behavioral detection thresholds, auditory filter widths, and temporal modulation transfer functions were obtained from four starlings before, during and after 11 days of subcutaneous injections of kanamycin, an aminoglycoside antibiotic. Birds were operantly conditioned to respond to pure tones and amplitude modulated noises ranging in frequency from 0.25 to 7 kHz using adaptive staircase proce...

Four waterfowl were collected in the Tri-State Mining District (Oklahoma, Kansas and Missouri, USA), an area known to be contaminated with lead, cadmium and zinc (Zn). They were part of a larger group of 20 waterfowl collected to determine the exposure of birds to metal contamination at the site. The four waterfowl (three Branta canadensis, one Anas platyrhynchos) had mild to severe degenerativ...

Attributes of an animal's life history, such as reproductive rate or longevity, typically fall along a 'slow-fast' continuum. Animals at the fast end of this continuum, such as temperate birds, are thought to experience high rates of mortality and invest more resources in reproduction, whereas animals at the slow end, such as tropical birds, live longer, have fewer offspring and invest more res...

The immune response of turkeys to live attenuated vaccine for avian pathogenic Escherichia coli (APEC) constructed from O78 strain was evaluated, where ninety-one-day old turkeys were vaccinated twice with 3 weeks intervals. Other thirty turkeys were kept as non-vaccinated control. Birds were challenged against homologous O78 and heterologous O1 and O2 pathogenic strains of E. coli using 107 CF...

an f2 japanese quail population was developed by crossing two strains (wild and white) to map quantitative trait loci (qtl) for performance and carcass traits. a total of 472 f2 birds were reared and slaughtered at 42 days of age. performance and carcass traits were measured on all of the f2 individuals. parental (p0), f1 and f2 individuals were genotyped with 3 microsatellites from quail chrom...

To achieve complete anatomic central hepatectomy for a large tumor compressing surrounding vessels, transection by an anterior approach is preferred but a skillful technique is necessary. We propose the modified technique of Belghiti's liver hanging maneuver (LHM). The case was a 77-year-old female with a 6-cm liver cystic tumor in the central liver compressing hilar vessels and the right hepat...

The study was designed to recognize the effects of flavonoids isolated from a Brassica oleracea plant minimize damage caused by diabetes induced alloxan in histological structure liver and levels (AST,ALT) congeneric.
 Fifteen female albino rats were used divided into three groups equal: First group: control animals given water food, Second treated alloxan, Third treatmed flavonol peritone...

1. Fatty livers and kidney syndrome (FLKS) was induced in young broiler chickens by giving them a diet composed principally of wheat and meat meal. 2. FLKS resulted in reduced growth and increased liver weight; fasting for 18 h increased mortality, liver lipid and the specific activity of hepatic ATP-citrate lyase compared with birds fed on a commercial diet. The specific activities of hepatic ...

OBJECTIVE OBJECTIVE To evaluate diclofenac-induced biochemical and histopathological changes in White Leghorn birds. MATERIALS AND METHODS Six-week-old birds were equally divided into three groups of six birds each. Group I served as control and received vehicle orally. The birds of Group II and III were orally administered with a single low (2 mg/kg) and high dose (20 mg/kg) of diclofenac...
