Enriching Eggs of Laying Hens with Multiple Bioactive Nutrients for Improving Human Health
… When these compounds are transported into yolks, their molecular forms are changed to be incorporated into phospholipids in the case of DHA, bound to proteins, or hydroxylated such as calcitriol. In order to evaluate how the metabolism of the laying hens changes the bioavailability and …

Dieldrin Residues In Eggs and Fat of Penned Pheasant Hens
… compare: (1) the trend of dieldrin deposition in yolks of eggs from hen pheasants ted different levels of the insecticide, (2) the trend of dieldrin deposition in the egg yolks after termination of treatment, and (3) the level of dieldrin in the fat of the birds after the egg laying period. This …

A genetic analysis of reproduction in growth selected lines of chickens
… percentage hen-day production of normal eggs and yolks were similar and ranged from 0.19 to 0.41 indicating common genetic factors controlling these traits. Heritabilities of the composit trait, total defective eggs, ranged from 0.26 to 0.48. Genetic correlations were generally higher than the …

Laying-Sequence Variation in Yolk Carotenoids of Eastern Bluebirds
… the clutch. I found five carotenoids in the egg yolks of Eastern Bluebirds: lutein, β-carotene, zeaxanthin, astaxanthin, and β-cryptoxanthin. As predicted, the egg mass, egg length, and egg width did not vary significantly across the clutch.</p>

Unifying ecosystem concepts and mercury biomagnification in an estuarine environment using stable isotopes (delta-carbon-13 and delta nitrogen-15).
… (8) double crested cormorant eggs (whites and yolks). The results of this analysis show that for this coastal ecosystem, no distinction can be made in delta13C and delta15N values between estuarine and marine primary producers and filter-feeding fish, whereas freshwater fish and submerged …

Effects Of Cholesterol On Bovine Sperm Survival During Cooling and Freezing
… viability while studies using high cholesterol yolks demonstrated improved i motility with both the 0.5% and 1.0% diet. The results of this study indicate that treatment with CD/CHOL does not affect motility or viability, while treatment with high cholesterol yolk does. ii

Urbanization's Effects on Avian Morphology, Hormones, and Behavior Across Ontogeny
… of maternal thyroxine concentrations in urban yolks. Lastly, we provide experimental evidence that limited food, i.e. , reduced insect abundance, in urban environments is likely the urban ecological pressure driving these differences in morphology, maternal hormone transfer, and physiological …

PROSTAGLANDIN E2 PATHWAY AS A TARGET TO PREVENT AND TREAT OVARIAN CANCER IN LAYING HENS
… OM3-FAs andomega-6 fatty acids contents of egg yolks were determined by gas chromatography. Proliferation, apoptosis,COX-1, COX-2 and prostaglandin receptor subtype 4 (EP4) protein and mRNA expression and PGE2 concentration in ovaries were measured by PCNA, TUNEL, western blot, quantitative …

Utilization of Yolk as a Feed Source in Newly Hatched Chicks With and Without Vitellin
Increasing feed efficiency and early body weight gain has always been a top priority in the poultry industry. This experiment was designed to study the effects of feed sources differing in energy and protein levels as well as yolk removal on behavior, feed efficiency, energy intake, body weight and …

The Effects of Dietary Lipids on Bone Chemical, Mechanical and Histological Properties in Japanese Quail (Coturnix C. Japonica)
… the accumulation of trans-18:1 fatty acid in egg yolks and tibiae at hatch. The addition of FO or HSBO to the maternal diet significantly lowered the ex vivo PGE2 production of tibiae in newly hatched quail compared to those from hens given the SBO or CF diets (P<0.01). In Exp. 2, the addition of …
