Space use and navigation ability of hens at housing in the aviary for the laying phase: effect of enrichment with additional perches and genotype

open access: yesPoultry Science, 2023
: The present study tested the hypothesis that increased availability of perches could favor the adaptation and navigation ability of pullets of different genotypes at housing in a new aviary system for the laying phase.

The Effects of Perch Cooling on Behavior, Welfare Criteria, Performance, and Litter Quality of Broilers Reared at High Temperatures with Different Litter Thicknesses [PDF]

open access: yesBrazilian Journal of Poultry Science, 2020
The first aim of this study was to investigate the effects of perch cooling and different litter thicknesses on litter quality of the housing facility, welfare criteria (incidence of footpad and hock burns, gait score, plumage cleanliness and damages ...

Effects of Perching on Poultry Welfare and Production: A Review

open access: yesPoultry, 2023
Perching is one of the essential natural behaviors for avian species. Providing an optimal perching design (e.g., shape, dimension, and materials) for commercial poultry production is critical for maintaining bird health, welfare, and production ...

Artificial Perches: Ecological and Functional Aspects of its Contribution in the Atlantic Forest

open access: yesFloresta e Ambiente, 2020
Ecological restoration through conventional plantation techniques can create forests with low biodiversity. As such, one way to overcome possible shortcomings of the restoration process is to use nucleation techniques, such as artificial perches.

Rearing system and behavioural adaptation of laying hens to furnished cages Sistema de cria e adaptação comportamental de poedeiras às gaiolas enriquecidas

open access: yesCiência Rural, 2008
The influences of floor and cage-rearing on behavioural adaptation to furnished cages were investigated in laying hens. Two groups of 180 Isa Brown commercial layer pullets were reared in cages (CR) or floor pens (FR) and transferred to furnished cages ...

Phylogenomic history of enigmatic pygmy perches: implications for biogeography, taxonomy and conservation [PDF]

open access: yesRoyal Society Open Science, 2018
Pygmy perches (Percichthyidae) are a group of poorly dispersing freshwater fishes that have a puzzling biogeographic disjunction across southern Australia. Current understanding of pygmy perch phylogenetic relationships suggests past east–west migrations

Keel bone damage in laying hens reared in different production systems in Serbia [PDF]

open access: yesBiotechnology in Animal Husbandry, 2017
The European Union in 2012 banned conventional battery cages for the welfare reasons. However, transition to new housing systems uncovered some new problems, such as keel bone damage (KBD), which also could endanger welfare of laying hens.

Linear Space Requirements and Perch Use of Conventional Layer Hybrids and Dual-Purpose Hens in an Aviary System

open access: yesFrontiers in Veterinary Science, 2019
Roosting on elevated perches is a behavioral priority in laying hens, which is well-investigated in both experimental and commercial settings. However, little is known about perching behavior and perch requirements of alternative hybrids, such as dual ...

Comparative analysis of birdlife in different ecological restoration methods with emphasis in the role of artificial perches

open access: yesRevista de Biologia Neotropical, 2018
Artificial perches provide complexity to the landscape, a factor that can increase animal biodiversity. We tested the hypothesis that artificial perches used in ecological restoration promoting increased of the specific birdlife diversity in a restored ...
