Oxytetracycline transfer into chicken egg yolk or albumen.
This study was conducted to determine whether the approved doses of oxytetracycline (OTC) for breeder hens and meat-type poultry would produce drug residue transfer into egg components when fed to laying hens. Twenty hens were assigned to equal groups (n = 10) and fed either 50 or 200 g/ton OTC for 5 d. Oxytetracycline concentrations in egg components were determined daily during a 2-d pretreat...
متن کاملOccurrence of glycosphingolipids in chicken egg yolk.
Chicken egg yolk was found to contain a unique glycosphingolipid pattern not seen in other types of tissue or cell. These glycosphingolipids were isolated in pure form and their structures established by sequential enzymic hydrolysis and permethylation analysis. The major gangliosides in chicken egg yolk are N-acetylneuraminosylgalactosylceramide, N-acetylneuraminosyl-lactosylceramide and di-N-...
متن کاملSpecific Chicken Egg Yolk Antibodies against Enterotoxigenic Escherichia coli K99 in Serum and Egg Yolk of Immunized Laying Hens
Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...

Informal care is a vital pillar of the British welfare state. A well-known fact in the small economic literature on informal care is the apparent negative relation between care responsibilities and labour market participation. Yet, caring and labour market participation may be endogenous. Using an instrumental variable approach and panel data techniques and employing data from the British House...
متن کاملAcoustic properties of egg yolk and albumen in the frequency range 20-400 MHz.
The acoustic propagation properties of egg yolk and albumen are characterized in the frequency range 20-400 MHz by the bioultrasonic spectroscopy system using an ultrasonic transmission comparison method. Significant differences in the attenuation, velocity, impedance, and density among yolk and thick and outer thin albumen are observed. The acoustic properties of 10% aqueous solutions of ovalb...
