This study was designed to evaluate efficacy of polyherbal hypocholesterolemic supplement AV/HLP/16 (test compound) on serum and egg yolk cholesterol levels and egg quality parameters in layers. One hundred and twenty healthy White Leghorn (BV 300 strain) of 54 weeks age were randomly divided into four treatments (T 0 , T 1 , T 2 , T 3 ); subdivided into three replicates with ten birds in each ...

Sex steroids of presumably maternal origin have been found in avian, crocodilian, and chelonian egg yolks, and they can affect offspring morphology and behavior. The present study reports testosterone (T) levels to which embryos are potentially exposed in the green anole (Anolis carolinensis), a lizard with genotypic sex determination. We documented plasma and yolk T concentrations in adult fem...

Č������ H., V������� M., P���������� V., K�������� F. (2004): Determination of egg yolk content in egg liqueurs. Czech J. Food Sci., 22: 9–15. The recent Czech Food law (Decree No. 264/2003, 93/2000 and 57/2003 of the law No. 110/1997 as amended) requires the minimal concentration of egg or egg yolk content in relevant food products (mayonnaises, egg pastas, egg liqueurs), however, the methods ...

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...

In recent years, there have been a number of advances in the pathogenesis and treatment of atherosclerosis and in assessing prognosis in carotid atherosclerosis. Risk stratification to improve vascular prevention by identifying patients most likely to benefit from intensive therapy is much improved by measuring carotid plaque burden. In patients with asymptomatic carotid stenosis, a number of m...

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...

OBJECTIVES Atherosclerosis is the main leading cause of cardiovascular diseases. The purpose of this study was to assess the potential preventive effect of egg yolk HDL on the atherosclerosis plaque formation. MATERIALS AND METHODS Thirty rabbits were divided into five groups: A; normal diet, B; hyper-cholesterolemic diet, C; hypercholesterolemic + 400 mg/kg egg yolk HDL D; hypercholesterolem...

The effect of a dietary supplementation of gallic acid and linoleic acid mixture (MGL) and their synthetic salt, sodium 2,3-dihydroxy-5-(((9E,12E)-octadeca-9,12-dienyloxy)carbonyl)phenolate (NGL), on egg quality was investigated. A total of 120 laying hens were allotted into five groups over 4weeks of the experimental period. Birds were fed the following diets: (1) control [commercial diet (CD)...

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...
