Effects of Broiler Breeder Age on Egg Quality, Incubation Performance, and Early Progeny Physiological and Muscle Fiber Development

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of breeder hen age on the incubation performance, embryonic development, and progeny quality of Cobb500 broiler breeders at 39, 51, and 69 weeks of age. A total of 870 eggs were collected, of which 810 were incubated; these were assigned to a completely randomized design with three treatments and nine ...

Effects of Dietary Activated Charcoal Supplementation on Performance, Egg Quality, and Bone Calcification in Laying Hens Exposed to High Fluoride

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The aim of the present study was to determine the effects of high dietary fluoride intake on performance, egg quality, serum biochemical parameters, bone tissue, mineral accumulation, and the expression of selected mineralisation‐related genes in laying hens, and to evaluate whether these effects could be alleviated by dietary activated ...

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Home sweet harm: Confinement and tranquilidad in post‐asylum Peru

Medical Anthropology Quarterly, EarlyView.
Abstract This article examines how Peru's Community Mental Health (CMH) model contributes to the exclusion and home confinement of mentally ill individuals. Based on the experience of a woman diagnosed with schizophrenia and her mother, I show how CMH's emphasis on community‐based care often fails in practice, as neighbors respond to people with mental

Perinatal development and nutrient utilization in chickens : effects of incubation conditions

, 2010
Suboptimal incubation conditions can negatively affect survival and development of chicken embryos. However, physiological mechanisms that may explain these effects, and the long-lasting consequences are largely unknown.

Navigating troubled waters: Posthumanist vulnerability and entanglement in Richard Powers's Playground (2024)

Orbis Litterarum, EarlyView.
Abstract Richard Powers's most recent novels to date—The Overstory (2018), Bewilderment (2021), and Playground (2024)—engage with some of the environmental and technological threats that loom over our planet, such as deforestation, species loss, the degradation of the ocean bottom, and the risks associated with the development of generative AI ...

Deterioration of Eggshell Quality and Calcium Metabolism in Laying Hens

, 1978
The present study was undertaken to: (1) develop a reliable method of measuring eggshell quality, (2) determine whether diet alterations that cause a somewhat reduced rate of egg production could influence shell quality, and (3) determine whether certain
