Assessment of a program for monitoring antimicrobial purchase and resistance in Escherichia coli and Salmonella enterica on pig farms in the Midwestern United States from May 2020 through October 2023 Open
Introduction Antimicrobial resistance (AMR) poses significant challenges to health and treatment options in both human and veterinary medicine. Animal AMR monitoring in the US evaluates carcasses, retail meat, live animals, and diagnostic …

249 Effects of number of pigs per feeder space hole in wet-dry feeders on the growth performance of pigs raised in a commercial farm from weaning to finish Open
This study evaluated the effects of number of pigs per feeder hole (wet-dry feeders) on the growth performance of pigs raised in commercial wean-to-finish facility. 2,240 pigs (PIC®Camborough × PIC®800) were used in a RCBD (Block =Weight) …

Evaluation of antibiotic purchase data for ceftiofur and enrofloxacin and minimum inhibitory concentrations among Escherichia coli isolates from swine farms in the Midwestern United States using multiple statistical models Open
Antimicrobial resistance is considered a global One Health threat. Controlling selection pressure by reducing antibiotic use in livestock is a significant component of the response to this threat. The science concerning use and resistance …

Further Evidence That Science-Based Biosecurity Provides Sustainable Prevention of Porcine Reproductive and Respiratory Syndrome Virus Infection and Improved Productivity in Swine Breeding Herds Open
Porcine reproductive and respiratory syndrome virus (PRRSV) is a globally significant pathogen of pigs. Preventing the entry of PRRSV into swine breeding herds enhances animal health and welfare. A recently published retrospective cohort s…

229 Effects of sire line on survivability traits of commercial pigs sired by PIC 800 or a North American competitor Duroc Line from birth to market Open
This study aimed to evaluate differences in survivability traits on pigs originating from two sire lines from birth to market. A total of 28,426 commercial pigs sired by either PIC 800 boars (n = 13,960 pigs) or a North American competitor…

Carcass cutting yields and meat quality of market gilts managed with immunological suppression of ovarian function and estrus Open
The objective of this study was to analyze the effects of immunological suppression of ovarian function and estrus (Improvest®; Zoetis Inc.) on carcass cutting yields and meat quality. A total of 1,080 gilts were allocated by weight and as…

Antimicrobial use and antimicrobial resistance monitoring in pig production in the United States of America Open
Monitoring antimicrobial use (AMU) and antimicrobial resistance (AMR) on farms is recognised as an important component of antimicrobial stewardship, yet the process can be resource intensive. This paper describes a subset of findings from …

309 Achieving Heavier Market Weights, with Similar Feed Efficiency, in Gilts Administered Improves Open
Previous reports indicate that gilts administered Improvest will have an increased ADFI, ADG, and heavier market weights. Feeder type may influence growth performance and feed efficiency. Prior to the initiation of this study, pigs were pl…
View article: Evaluation of the Impact of Antimicrobial Use Protocols in Porcine Reproductive and Respiratory Syndrome Virus-Infected Swine on Phenotypic Antimicrobial Resistance Patterns
Evaluation of the Impact of Antimicrobial Use Protocols in Porcine Reproductive and Respiratory Syndrome Virus-Infected Swine on Phenotypic Antimicrobial Resistance Patterns Open
Despite a recognized need for more longitudinal studies to assess the effects of antimicrobial use on resistance in food animals, they remain sparse in the literature, and most longitudinal studies of pigs have been observational. The curr…

The effect of extended storage on virus survival in feed Open
Extended feed storage to reduce the risk of virus survival has not been tested experimentally. Five ingredients inoculated with porcine epidemic diarrhea virus, porcine reproductive and respiratory syndrome virus-174, and Senecavirus A wer…

Evidence of viral survival in representative volumes of feed and feed ingredients during long‐distance commercial transport across the continental United States Open
The hypothesis that feed ingredients could serve as vehicles for the transport and transmission of viral pathogens was first validated under laboratory conditions. To bridge the gap from the laboratory to the field, this current project te…
