MULTIPLE REGRESSION ANALYSIS OF EGGSHELL MEASUREMENTS IN TWO GENETIC GROUPS OF CHICKEN [PDF]

Journal of Animal and Poultry Production, 2008
The research was conducted on eggs of 148 heterozygous naked neck (Nana) and 124 normally feathered (nana) genotype chickens maintained in individually cages. Three hundred eggs selected randomly (150 each).

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

Advanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Effects of Eggshell Quality and Broiler Breeder Age on Hatchability

Poultry Science, 1994
The effects of eggshell quality and breeder age were assessed on egg weight loss during incubation, fertility, hatchability, and embryonic mortality. The trials involved hatching eggs from three commercial broiler breeder flocks of the same strain but of different ages. The eggs were divided according to specific gravity into two groups, thin-shelled (<

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Effect of limestone particle size on performance, eggshell quality, bone strength, and in vitro/in vivo solubility in laying hens: a meta-analysis approach

Poultry Science, 2022
: Numerous publications over the past 5 decades have investigated the effect of limestone particle size (LmPS) on production performance, bone mineralization, and limestone solubilization in laying hens.

Effects of UVB light on laying hens and eggshell quality [PDF]

, 2018
The effects of UVB lights on laying hens and eggshell quality were investigated in this study. UVB light treatment was provided by Philips TL 20W/12 RS SLV/25 tube light. The lights were on 2x30 min per day and were turned on during feeding.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Is the Eggshell Quality Influenced by the Egg Weight or the Breeder Age?

Brazilian Journal of Poultry Science
For a long time, it has been said that eggshell quality decreases as eggs increase in size, but this increase is seen as the breeder age advances. Therefore, the present study aimed to evaluate the age and egg weight effect on Cobb 500 broiler breeders ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.
