The purpose of this survey was to collect basic data on breeding systems of animal welfare-approved laying hen farms in Korea. Questionnaires were mailed to 64 animal welfare-approved farms, and 20 questionnaires (31.3%) were returned. The housing systems were fabric coverlet (4 farms, representing ...

Livestock animals, especially poultry, are a known reservoir for extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli). They may enter the pen either via positive day-old chicks or via the environment. We developed a mathematical model to illustrate the entry and...

This study was carried out to investigate the effects of high stocking density on growth performance, villus and liver cell morphology, cecum bacteria and heat shock proteins (HSPs) gene expression in meat duck (Cherry valley, Anas platyrhynchos) reared under heat stress (HS). A total of 180 meat...

This study evaluated the effects of different sources of insoluble fiber at different cage densities on egg performance, egg quality, tibia characteristics, and cecal microbial population of 70-week-old Hy-Line W-36 for 10 weeks. A total of 120 laying hens were allocated to six treatments,...

Aims: This study explored how dairy farm operating systems with free-stall or tie-stall housing and cow hygiene score influence the occurrence of zoonotic bacteria in raw milk. Methods and Results: Samples from bulk tank milk (BTM), milk filters, faeces, feed, teats and teat milk were collected...

The objective of this study was to compare the performance, egg quality, and microbial contamination of egg shells from hens maintained in different housing systems, such as conventional and enriched cages, litter, and aviaries. The housing system significantly (P<0.001) influenced the performance characteristics. The highest egg production, lowest daily feed consumption, and feed conversion ratio were measured in conventional cages compared to litter and ...

Nine pig farms were evaluated for the welfare quality in Korea using animal- and environment-based parameters (particularly air quality parameters) during the winter of 2013. The Welfare Quality® (WQ®) protocol consists of 12 criteria within four principles. The WQ® protocol classifies farms into...

In this study, a new housing system for broiler was tested. This system consisted of a slatted floor area and a littered area with the aim of improving litter quality. Two experimental broiler houses were provided. In house 1, a slatted floor was installed below the drinker and feedlines. Littered...

The study was carried out to compare the growth performance, gut microbiota, incidence of footpad dermatitis (FPD), leg weakness, physiological, and immunological responses in broilers kept in cage (CS) and floor pen (FS) rearing systems under a tropical environment. One-day-old male Cobb 500...

With the continuous increase of large-wale pig farms, the disinfection of pig farm environment plays an extremely important part in the control and prevention of pig fame diseases in high-density breeding environment. As an important breeding place for pig farms, the farrowing house must be...
