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...

Internal and external quality characters of poultry eggs are quitely important to determine egg weight. Also, the is for both hatching production. The purpose this study was modelling weight with MARS (Multivariate Adaptive Regression Splines) method using inner outsider in Lohmann LSL Classic white hybrit flock. For purpose, hybrid flock (n=60) were used. Weekly yields evaluated from 22nd week...

   One of the main problems of multiple-trait genetic evaluation in poultry breeding is high computing costs. Principal components analysis (PCA) is a method for reducing the number of traits in correlated trait analysis. The aim of the present study was to determine the most effective principal components (PCs) of internal egg quality and some performance traits of Azarbayjan native chickens. ...

A total number of one hundred and fifty-three females and males of Japanese quail at 14 weeks of age were used with sex ratio 2 female / 1 male to study the effect of maternal body weight, some blood parameters and egg quality traits on fertility% (F%), hatchability% for total and fertile eggs (H/TE % and H/FE %), and chick weight (CW). Birds classified into three groups (light, medium and heav...

Table eggs collected at random from one-hundred and fifty layers (75-FUNAAB-Alpha 75- ISA brown) kept Breeding Unit, Teaching Research Farm, Olusegun Agagu University of Science Technology, Okitipupa 31st, 33rd, 35th weeks (WK) age were analyzed for internal external characteristics within 24 hours laying. The data subjected to analysis variance assess the effect breed on egg quality. Breed had...

Monkeys with excellent reproductive histories were immunized with the laminin peptides YIGSR, RGD, IKVAV, and YD, a control sequence with no known biological function. Sera from the YIGSR-immunized monkey became toxic, causing neural tube defects in whole rat embryo cultures, and this monkey experienced fetal loss after immunization. Sera from the RGD-immunized monkey also became embryotoxic in...

A description of the fine structure of the yolk of the unincubated hen's egg has been provided, which will serve as a basis for further studies on yolk digestion. The gross components of the yolk (that is, free-floating lipid drops, yellow and white yolk spheres together with their enclosed lipid subdroplets, and aqueous protein fluid) could be recognized by phase contrast and low power electro...

This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...

The present investigation describes the fine structural changes that occur during proteid yolk formation in the developing oocytes of the guppy (Lebistes reticulatus), an ovoviviparous teleost. These changes suggest the operation of a number of different intra- and extraoocyte processes that may account for the synthesis and deposition of the proteid yolk. Early in oogenesis, the egg's Golgi sy...
