Abstract Background There is concern that the use of antimicrobials in livestock production has a role emergence and dissemination antimicrobial resistance animals humans. Consequently, there are increasing efforts to reduce (AMU) agriculture. As largest consumer veterinary several countries, pig sector particular focus these efforts. Data on AMU Ireland lacking. This study aimed quantify Irish farms, identify major patterns employed compare results obtained those from other published...
Post-weaning diarrhoea (PWD) is a multifactorial disease that affects piglets after weaning, contributing to productive and economic losses. Its control includes the use of in-feed prophylactic antibiotics therapeutic zinc oxide (ZnO), treatments that, since 2022, are no longer permitted in European Union due spread antimicrobial resistance genes pollution soil with heavy metals. A dysbiosis microbiota has been suggested as potential risk factor PWD onset. Understanding pig's development...
On-farm hatching (OH) systems are becoming more common in broiler production. Hatching conditions differ from conventional farms as OH chicks avoid exposure to handling, transport, post-hatch water and feed deprivation. In contrast, (CH) exposed standard hatchery procedures transported post hatching. The objectives of this pilot study were investigate the prevalence frequency Escherichia coli resistant antimicrobials, including presumptive ESBL/AmpC-producing E. coli, isolated environmental...
The need to reduce antimicrobial use (AMU) in livestock production has led the establishment of national AMU data collection systems several countries. However, there is currently no consensus on which indicator should be used and many have defined their own indicators. This study sought explore effect using different internationally recognized indicators collected from Irish pig farms determine if they influenced ranking a benchmarking system. for 2016 was 67 (c. 35% production). Benchmarks...
The threat to public health posed by antimicrobial resistance in livestock production means that the pig sector is a particular focus for efforts reduce use (AMU). This study sought investigate risk factors AMU Irish production. Antimicrobial data were collected from 52 farrow-to-finish farms. investigated farm characteristics and performance, biosecurity practices, prevalence of pluck lesions at slaughter serological status four common respiratory pathogens vaccination prophylactic...
Abstract The objective of this study was to identify biosecurity practices associated with antimicrobial usage (AMU, mg/live body weight, BW) in pig farms. Biosecurity were assessed using the Biocheck.UGentTM questionnaire 54 Irish farrow-to-finish For each farm, information on in-feed and water critically important antimicrobials (CIA) collected. Data analysed univariable general linear models PROC GLM SAS v9.4. Results are presented as least square means ± SE. In-feed AMU lower farms where...
Three levels of melengestrol acetate (30, 60, and 90 mg) injected subcutaneously as a liquid (DEPO-MGA ®) in the ear heifers yielded high performance results comparable to feeding 0.5 mg MGA per head daily. Heifers fed daily gained 6% faster were 11% more efficient than not receiving MGA. This study will be pooled with trials from 13 other locations U.S. determine if further development FDA clearance DEPO-MGA ® pursued by Upjohn Company.
