Alterations in lipid composition of plasma lipoproteins during deposition of egg yolk.
The profiles of total lipids and of the molecular species of individual lipid classes were compared among corresponding lipoproteins of plasma and yolk of the laying hen. A close qualitative correspondence was found in the makeup of the molecular species of glycerophospholipids and triglycerides of the very low density lipoproteins and the high density lipoproteins of plasma and yolk. There was...
متن کاملVariations in the composition of egg-yolk pigment.
Gillam & Heilbron (1935) in a study of the effects of feeding maize and grass on the composition of yolk pigment have shown that xanthophyll is the principal pigment of egg yolk, although cryptoxanthin and B-carotene are also present, the former sometimes in amounts that contribute appreciably to the total vitamin A activity of the yolk. In view of this, the extent of the variations in the cryp...
متن کاملEffects of egg yolk and salt on Micrococcaceae heat resistance.
The heat resistance and growth possibilities of various members of the Micrococcaceae in egg yolk and egg yolk with added salt were determined. Egg yolk alone protected members of the Micrococcaceae considerably against heat. Whereas in water Staphylococcus aureus S6 had a decimal reduction time (D) value of 66 s at 55 degrees C, its D value in egg yolk at the same temperature was 246 s. In sal...
متن کاملEffect of Dietary Marine Microalgae (Schizochytrium) Powder on Egg Production, Blood Lipid Profiles, Egg Quality, and Fatty Acid Composition of Egg Yolk in Layers
Two hundred and sixteen Institut de Sélection Animale (ISA) brown layers (40 wks of age) were studied for 6 wks to examine the effect of microalgae powder (MAP) on egg production, egg quality, blood lipid profile, and fatty acid concentration of egg yolk. Dietary treatments were as follows: i) CON (basal diet), ii) 0.5% MAP (CON+0.5% Schizochytrium powder), and iii) 1.0% MAP (CON+1.0% Schizochy...
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...
