Histology of the Ovary of the Laying Hen (Gallus domesticus)

open access: yesVeterinary Sciences, 2017
The laying hen (Gallus domesticus) is a robust animal model for epithelial ovarian cancer. The use of animal models is critical in identifying early disease markers and developing and testing chemotherapies. We describe the microscopic characteristics of

Variation in digestibility parameters related to feed efficiency between and within two laying hen lines [PDF]

open access: yesPoultry Science
To meet the increasing demand for eggs, while limiting the environmental impact, an increased efficiency of laying hen production is required. Feed efficiency (FE) plays a major role in this.

Implications for welfare, productivity and sustainability of the variation in reported levels of mortality for laying hen flocks kept in different housing systems: A meta-analysis of ten studies [PDF]

open access: yesPLoS ONE, 2016
Data from ten sources comprising 3,851 flocks were modelled to identify variation in levels of mortality in laying hens. The predicted increase with age was curvilinear with significant variation between the seven breed categories. Mortality was higher

Deep Learning for Laying Hen Activity Recognition Using Wearable Sensors

open access: yesAgriculture, 2023
Laying hen activities in modern intensive housing systems can dramatically influence the policies needed for the optimal management of such systems. Intermittent monitoring of different behaviors during daytime cannot provide a good overview, since daily

The Effect of Hard Pecking Enrichment during Rear on Feather Cover, Feather Pecking Behaviour and Beak Length in Beak-Trimmed and Intact-Beak Laying Hen Pullets

open access: yesAnimals, 2022
Injurious pecking, commonly controlled by beak trimming (BT), is a widespread issue in laying hens associated with thwarted foraging. This controlled study compared the effect in intact and beak-trimmed pullets of providing pecking pans to eight ...
