Aim: The aim was to study the seroconversion and development of egg yolk immunoglobulins in adult laying White Leghorn hens immunized against an isolate of enterotoxigenic Escherichia coli (ETEC) bearing K91 and K88ac antigens, obtained from diarrheic piglet. Materials and Methods: Adult laying White Leghorn hens were immunized with inactivated enterotoxic E. coli strain isolated originally fro...

the present research was conducted to analyze the genetic structure of egg quality traits in japanese quail. external and internal egg quality traits were assessed on 1706 eggs of laying japanese quail. eggs were collected for 4 days at the quaits 10 weeks of age. the investigated traits were analyzed through univariate as well as multivariate animal models employing restricted maximum likeliho...

The aim of this study was to investigate the effect different age and plumage color on egg quality traits cholesterol levels, in addition which can be used for weight prediction Japanese quails. eggs obtained from 23-week-old original colored Jumbo quails, 39-week-old quails; 40, 20 were respectively as research material. In terms difference, when quails compared yolk weight, height, diameter h...

BACKGROUND Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day(-1) per hen of three coloured carrot varieties (orange, yellow and purple) as forage material in comparison with a standard feed control on egg production, egg yolk colour and deposition of carot...

The present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of Bovan Neva Black laying hens at 25, 51 and 72 weeks. For this purpose, thirty birds were selected from the layer flock in the Babcock University Teaching and Research Farm. They were individually housed in separate labeled battery cage. A total of thirty eggs were collected...

This study was conducted to investigate the effect of fenugreek and copper sulfate supplementation levels and their combinations in diets on productive, physiological performance, lipids profile in blood, liver or yolk, fertility and hatchability of Japanese quail for a period of 7 weeks (from 8 to 14 weeks). A total number of 162 mature Japanese quail birds were used in this study. Quail birds...

This study aimed to evaluate the effects of dietary egg yolk phosphatidylcholine (EPC) and soybean (SPC) on obesity mice fed a high-fat diet (HFD). After 60 days intervention, were evaluated by biochemical indices serum lipidomic analysis. EPC SPC markedly reduced total cholesterol, triacylglycerol (TAG) low-density lipoprotein while increased high-density cholesterol. was more effective in red...

Results In our cohort, 48% of patients were sensitized to egg white and yolk, while 52% were reacting to egg white exclusively. In allergen microarray, Gal d 1 and 2 were identified as major allergens for all patients, whereas Gal d 3-5 displayed high sensitization prevalence only in patients reacting to both egg components. Mean egg white-specific IgE was significantly higher in patients displ...

Of 92 drug-resistant Mycobacterium tuberculosis strains isolated from sputum specimens, 86 showed growth in two types of 7H12 broth, one with egg yolk and the other without egg yolk. In addition, two strains grew only in plain 7H12 broth without yolk, and four others were recovered only in the medium supplemented with egg yolk. The radiometrically detected growth was higher in the presence of e...
