Yi i.i.d. ∼ pθ∗ , i = {1, . . . , n} where θ∗ ∈ Θ. We can view pθ∗ as a member of a parametric class of distributions, P = {pθ}θ∈Θ. Our goal is to use the observations {Yi} to select an appropriate distribution (e.g., model) from P. We would like the selected distribution to be close to pθ in some sense. We use the negative log-likelihood loss function, defined as l(θ, Yi) = − log pθ(Yi). The e...

An experiment was conducted to determine the effect of dietary inclusion of Mycofix Select (Biomin GmbH, Herzogenburg, Austria) on discrete egg parameters and quality characteristics of hens fed mycotoxin-contaminated diets (aflatoxin; AFLA) and deoxynivalenol (DON)) during a 10-wk trial. A 4 × 2 factorial design was used with 4 contamination levels: control, low (0.5 mg/kg of AFLA + 1.0 mg/kg ...

To induce oocyte development, eels are weekly injected with salmon or carp pituitary extract (CPE). The handling and hormone peaks result in inferior quality; therefore, alternative treatments that improve quality reproductive success require investigation. enhancement of early sexual maturation by a single injection human chorionic gonadotropin (hCG), administered prior to CPE treatment, was i...

ii Egg yolk contamination of egg whites continues to be a serious problem in the egg industry. The ability of egg whites to form stable and voluminous foams is greatly inhibited by accidental yolk contamination, even at extremely small levels. Experiments were conducted to determine if lipase can regenerate the functional properties of yolkcontaminated egg whites. Treatments included control, 0...

this study was conducted to evaluate the effect of egg yolk and cooling on ram coated spermatozoa. semen was collected from three ram by artificial vagina contacted with a tube containing tris- fructose-egg yolk 15%. samples were pooled, centrifuged by 700 g for 10 min and removed supernatant. then, samples were diluted by tris-glucose and centrifuged again to remove seminal plasma and egg yolk...

Yolk retention and yolk sac infection is considered as an important cause of death in chicken as well as in guinea fowl, duck, turkey, quail and goose. The factors which slow down the rate of yolk absorption and may in turn, lead to yolk retention are discussed. Yolk sac infection of bacterial origin is most important among these factors. Other factors which may contribute include posthatch sta...

The breast can be diffusely affected by a variety of specifi c and unique disorders, including benign disorders that are closely related to physiologic changes and infl ammatory and infectious diseases, as well as by benign and malignant tumors. The clinical manifestations include unilateral or bilateral breast enlargement with/without a palpable masses, shrinkage and breast asymmetry. Thus, kn...

AIMS The present study aimed to determine whether yolk sacs with abnormal sonographic appearance are associated with adverse perinatal outcomes in both early and late gestation. MATERIAL AND METHODS A total of 305 viable singleton pregnancies with gestational age of 6 to 9 weeks were prospectively evaluated with respect to perinatal outcomes and sonographic characteristics of the yolk sacs. ...

BACKGROUND Hen's egg allergy is a frequent cause of childhood food allergy. Egg yolk is used in various commonly consumed foods; if children with allergy to hen's egg could eat heated egg yolk, their quality of life (QOL) would improve. No reports exist regarding oral food challenges (OFCs) for heated egg yolk. We aimed to clarify whether pediatric patients allergic to hen's egg could consume h...
