Providing optimal calf care remains a challenge on many dairy farms and has important implications for the future health, welfare, productivity of male female calves. Recent research suggests that calves receive lower quality early in life than calves, but further investigation is required to determine factors influence this disparity. The objectives study were understand producer perspectives neonatal practices explore differences between care. Overall, 23 producers Ontario, Canada,...
Little is known regarding the biofilm forming capabilities of a somewhat distinct population Salmonellae present on-farm and responsible for illnesses in livestock humans. Evaluation cleaning disinfection preharvest environments has found little success eradicating Salmonella biofilms to date. Disrupting environmental survival via removal will be critical reducing carriage reservoirs risk foodborne illness. Therefore, objective this study was characterize abilities relevant human health....
Salmonella Dublin (S. Dublin), a host-adapted serovar, is capable of causing disease in both humans and cattle. Infected animals are prone to becoming long-term carriers, shedding the pathogen, contaminating environment, sustaining cycle on farm. Traditional culture methods often less sensitive for detecting pathogen environmental samples, limiting our ability understand its prevalence epidemiology. Therefore, integrating culture-independent techniques imperative enhance capacity identify...
Cleaning and disinfection are common control methods to reduce Salmonella transmission in cattle herds. However, cleaning protocols have had varied effectiveness against farm environments, residual contamination is often reported. Biocide choice critical when designing effective cleaning protocols, yet little known regarding susceptibility commercial products. Our objective was determine the minimum bactericidal concentration (MBC), defined as ≥ 3 log reduction, of 6 biocides used...
Male dairy calves are often sold from the farm of birth within first few days life. Research describing care male is limited, with an emphasis on parsing differences between and female calves. The aims this study were to describe producers’ self-reported practices for relative calves, as well their perceptions toward calf welfare. Overall, 24 producers in Ohio Indiana participated 1 in-person focus group (n = 10) or individually interviewed 14) using a semi-structured questionnaire closed...
Abstract Neonatal veal calves are highly susceptible to bacterial diseases. Occasional sub‐optimal early‐life care and long‐distance transportation result in high disease burden antimicrobial treatment incidence. Nonetheless, judicious use of antimicrobials is necessary mitigate the animal human health impacts resistance. The objective this cross‐sectional study was a clinical vignette‐based survey approach evaluate potential for reduced group or individual therapeutic use. included items...
Bovine coronavirus (BCoV) poses a threat to cattle health worldwide, contributing both respiratory and enteric diseases. However, few contemporary strains have been isolated. In this study, 71 samples (10 nasal 61 fecal) were collected from one farm in Ohio 2021 three farms Georgia 2023. They screened by BCoV-specific real-time reverse transcription-PCR, 15 BCoV-positive identified. Among them, five BCoV fecal isolated using human rectal tumor-18 (HRT-18) cells. The genomic sequences of...
ABSTRACT Introduction Antimicrobial resistance (AMR) is one of the leading public health threats globally. AMR genes can be transferred between bacteria through lateral gene transfer, and organisms spread environments by contaminated water, agriculture animals. Thus, widespread environmental dissemination transfer facilitate transmission pathways. Farm in dairy calf production are known to harbour that pose a risk for food contamination workers direct or indirect contact with Escherichia...
Livestock markets are critical hubs within animal trade networks that influence pathogen dissemination at the regional and national scale. Indeed, a 2016 Salmonella serovar Heidelberg outbreak, initially linked to surplus dairy calves livestock markets, sickened 63 people across 17 states. The objective of this repeated cross-sectional study was assess prevalence relatedness serovars public health relevance in Ohio Wisconsin markets. Twenty-four (14 from WI 10 OH) were enrolled study. Market...
Antimicrobial use in food-producing animals may contribute to the development of drug-resistant bacterial infections humans. Veterinarians prescribe and dispense antimicrobials, but farm caretakers are responsible for judging disease severity initiating on-farm treatments. The objective this study was estimate level agreement on antimicrobial treatment between respective veterinarians at different levels
