DOI: 10.1016/j.applanim.2021.105225
Abstract: Abstract Conventional broiler breeders are severely feed restricted during the rearing period, resulting in an unfulfilled behavioural need for performing feeding behaviour and likely in a sensation of hunger. As a response to the feed… read more here.

DOI: 10.1016/j.psj.2020.06.087
Abstract: Linezolid is an oxazolidinone class antibiotic used for treatment infections caused by various multidrug-resistant gram-positive pathogens including enterococci. However, recently, linezolid-resistant isolates in animals are considered as a human health hazard. In a broiler operation… read more here.
