Carcass composition, meat quality, leg muscle status, and its mRNA expression profile in broilers affected by valgus-varus deformity

Poultry Science, 2023
: Valgus-varus deformity (VVD) is a common leg disease in commercial broilers, which seriously affects animal welfare and causes economic losses. Up to now, most of the studies on VVD have been on skeleton, whereas there are fewer studies on VVD muscle ...

Low dose velogenic viscerotropic Newcastle disease virus infection caused 30% mortalities in Anak broilers but none in Lohmann Brown layer chickens

Journal of Applied Animal Research, 2018
The aim of this project was to find out the comparative susceptibilities of broilers and layer chickens to a low dose of velogenic viscerotropic Newcastle disease virus (vvNDV) infection using mortalities as the main indicator.

Use of an elevated platform with perforated surface and manure belt by fast-growing broilers on commercial farms

Poultry Science
: Like other members of the species Gallus gallus, fast-growing broilers are motivated to perch. However, broilers in the European Union are kept in unstructured barns, with no opportunity to sit elevated and rest undisturbed. A possible solution to this
