EFFICIENCY OF TABLE EGG PRODUCTION IN DIFFERENT HOUSING SYSTEMS AND FARM SIZES: A CASE STUDY BASED ON THREE HUNGARIAN FARMS [PDF]

Annals of the Polish Association of Agricultural and Agribusiness Economists, 2019
In the European Union, alternative housing systems (aviary, barn, free-range, organic) are increasingly used in laying hen populations (49.6%). Hungary is one of the member states where modified cage housing technology is prevalent, but this may change ...

Egg production in nests and nesting behaviour: genetic correlations with egg quality and BW for laying hens on the floor

Animal, 2023
In laying hen production, cage-free housing is growing rapidly to provide living conditions that meet hens’ needs. Unlike cages, this housing requires nests for automatic collection of eggs, as eggs laid outside nests must be collected by hand. Selecting

Thermal Response of Three Strains of Hens Housed in a Cage-Free Aviary at the Amazon Rainforest

Brazilian Journal of Poultry Science, 2021
ABSTRACT This study aimed to evaluate the thermal response of three strains of hens housed in a cage-free system at the Amazon rainforest in order to evaluate how feather coverage influences thermal exchange with the environment. The experimental method was completely randomized and treatments comprised three strains of hens (Rhode Island Red (red ...

Identification of reference genes for expression studies in the liver, and spleen of laying hens housed in cage and cage-free systems

Open Veterinary Journal, 2023
Background: The liver and spleen play a pivotal role in metabolism and immune response. During stress, neuroendocrine response induces changes in gene expression and its assessment demands the validation of the stability of the reference genes to perform relative gene expression experiments.
