Introduction:Pre-weaning piglet mortality is an important economic and welfare problem in commercial pig industry and is mainly due to an energy deficit. Management strategies, such as energy supplementation to neonatal piglets, are needed to reduce pre-weaning mortality. Energy supplements may provide directly energy to neonatal piglets as well as improve their colostrum intake. In practice, ener ...

Introduction:Pig herds are frequently infected with Salmonella Typhimurium. Infections are mostly subclinical and difficult to control with the currently available control measures. Vaccination might be effective to control Salmonella infections at farm level and hence be a promising tool to reduce the risk for human salmonellosis.Materials and Methods:In this study, five different vaccination str ...

1. IntroductionAntimicrobials have revolutionized modern medicine by enabling effective treatments for many life-threatening diseases and saving countless lives. However, the emergence and spread of antimicrobial resistance (AMR) among pathogens has become a global health issue affecting humans, animals, and environment [1]. Recognizing AMR as a critical challenge, the World Health Organization (W ...

Introduction: Colostrum intake (CI) by neonatal piglets is essential as colostrum is the sole external energy supply and provides immunological protection and growth factors. It is well known that insufficient CI is a major cause of pre-weaning mortality. Some authors have presumed long-term effects of CI on mortality and performance. However, studies investigating such long-term effects of CI are ...

Introduction:The aim of this study was to compare the effect of post-weaning treatment of piglets with zink oxide (ZnO) and colistin on health, production and Escherichia coli shedding.Materials and Methods:During two successive weaning rounds, a randomized control study was performed on three commercial pig herds. In each herd, four groups of weaners were created that either received colistin in ...

Introduction: The cross-contamination of non-medicated feed with residues of antimicrobials causes a public and animal health concern associated with the potential for selection and dissemination of resistance in commensal and potentially zoonotic bacteria. To identify the extent of the situation, we built a model that provides a way to estimate the percentage of cross-contaminated pig feed in tot ...
