 This study was designed to evaluate the supplementation of various concentrations selenium and vitamin E combinations in lactose egg-yolk-glycerol based extender on cryosurvival buffalo bull semen. The semen four healthy donor bulls ejaculates (n= 80) were processed pooled. collected extended with experimental extenders then frozen. frozen straws thawed analyzed for motility, viability, ...
We have investigated factors affecting iron distribution in the first-trimester gestational sac, by the measurement of transferrin, non-transferrin-bound iron (NTBI) and pro-hepcidin (Hep) in maternal serum, coelomic fluid (CF) and amniotic fluid (AF) and by immunostaining for Hep in villous and secondary yolk sac biopsies. These samples were obtained from 15 first-trimester pregnancies at 8-11...
The allocation of important but environmentally limited nutrients, such as carotenoids, often represents a trade-off between homeostasis and reproduction. However, key questions remain about how diet and species traits influence carotenoid allocation. We studied yolk carotenoid profiles and yolk color in relation to trophic level (based on delta(15)N values) in five species of seabirds belongin...
The site of deposition of Salmonella enteritidis in eggs could influence the extent to which this pathogen multiplies before refrigeration achieves growth-inhibiting internal temperatures. The first part of this study sought to determine whether S. enteritidis inoculated onto the exterior (vitelline) membrane surface of egg yolks was able to penetrate into and multiply within the yolk contents....
Protein by-products from the extraction of lecithin from egg yolk can be converted into value-added products, such as bioactive hydrolysates and peptides that have potential health enhancing antioxidant, and antihypertensive properties. In this study, the antioxidant and angiotensin converting enzyme (ACE) inhibitory activities of peptides isolated and purified from egg yolk protein were invest...
Introduction: Feathers are important body structures that act as surface insulators to reduce maintenance energy requirements and also to protect skin against abrasions and infection. The purpose of this study is to investigate the effects of methionine injection into the yolk sac on development of feather follicle in chicken embryo. Methods: 50 fertilized eggs (weighting 50±0.4 gr) of Ross×...
We have reported a strategic procedure for the preparation of human-type N-linked oligosaccharides targeting hen egg white and yolk. To determine whether the technique is applicable to other avian species, we performed comparative analysis of N-linked oligosaccharides derived from eggs of other pheasant species. Our investigation of the principal oligosaccharides resulted in several major findi...
Background & aims: Nowadays, one of the problems of the human society is drug addiction, which causes individual, economic, social and cultural damages. One of the most commonly used substances in circles and parties is ecstasy pills or 3,4-methylenedioxymethamphetamine (MDMA). These pills have severe damage to various systems of the body and brain. Therefore, in this study, we studied the anti...
Egg yolk is the most commonly used cryoprotective agent for sperm cryopreservation of several species.The objective of this experiment was to compare the effectiveness of egg yolk from four avian species(domestic chicken, duck, turkey and pigeon) on sperm quality following cryopreservation of the ram semen.Ejaculates were collected, using an electroejaculator, from six fertile rams. Samples wer...
Refrigeration to limit bacterial multiplication is a critical aspect of efforts to control the transmission of Salmonella enterica serovar Enteritidis (SE) to consumers of contaminated eggs. Although the nutrient-rich yolk interior is an uncommon location for SE contamination in freshly laid, naturally contaminated eggs, migration across the vitelline membrane could lead to rapid bacterial mult...
