131 Producer adoption of preconditioning strategies in the Oklahoma Quality Beef Network

Abstract The Oklahoma Quality Beef Network (OQBN) Vac-45 program was designed to provide health management certification and value-added marketing for cow-calf producers since 2001. The objective of this abstract is to examine trends in health management systems by OQBN participants. Participants chose from one of three options for administering vaccinations: Option 1) branding and weaning, Option 2) 2–6 weeks before weaning and weaning, Option 3) weaning and 14–28 d post weaning. From 2014–2018, 596 participants enrolled 30,452 calves. Preferred vaccine options were: Option 1) 210 participants (35%) and 12,015 calves (37%), Option 2) 96 participants (16%) and 3,016 calves (10%), Option 3) 290 participants (49%) and 15,421 calves (51%). Producer choice of a viral vaccine component included 251 (42%) participants using killed vaccine at least once. A five-yr average of cattle marketed with at least one modified-live vaccine (MLV) exposure was 73% of calves (22,138) and 27% (8,314) were treated with only killed vaccines. In Option 1, 57 (10% of the total) participants used killed vaccines at both times, 33 (6%) used a killed vaccine followed by a MLV at weaning, 120 (20%) used MLV at both times. Option 2, 55 (9%) participants used killed vaccines at both times, 4 (1%) participants used a killed vaccine follow by a MLV at weaning; 37 (6%) used a MLV at both times. Option 3, 114 (19%) participants used killed vaccines at both times, 2 (< 1%) participant used a killed vaccine followed by a MLV, 1 participant used MLV followed by killed vaccine, 173 (29%) participants used MLV at both times. Cattle marketed with killed vaccines have seen an increase in use; 2014 (27%), 2015 (17%), 2016 (27%), 2017 (31%), 2018 (39%). These data show the preferred method of MLV vaccination utilized is a weaning and post-weaning system with an increased use of killed vaccines, which may be due to producer concerns regarding exposure of brood cows to MLV.

Purpose The purpose of this paper is to demonstrate the value of using a systematic literature review to develop an integrated framework for information and knowledge management systems. Design/methodology/approach First, the systematic literature review method is introduced, differentiating it from traditional literature reviews in terms of value-added and limitations. Second, this methodology is used in a research application focused on absorptive capacity internal capabilities with regard to the processes of acquisition, assimilation, transformation and exploitation. Third, an integrated framework for information and knowledge management systems is developed from this application. Findings The systematic literature review approach provides a rigor that can assist in reducing researcher bias while simultaneously enabling the definition of a precise scope of review, with a clear explanation of selection criteria with the objective to find and review all the studies that are relevant to the search definitions. As a research method, it effectively supports a qualitative, quantitative or mixed methodology. Research limitations/implications This methodology was applied to one specific area of research. Specific limitations include the availability of articles in subscribed databases and the analytical capabilities of the tools used for text mining and analytics. Originality/value This paper demonstrates the usefulness of the systematic literature review methodology in developing an integrated framework for analysis.

Processing Fluid

AbstractIn the last two decades, in France, Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) stabilization protocols have been implemented using mass vaccination with a modified live vaccine (MLV), herd closure and biosecurity measures. Efficient surveillance for PRRSV is essential for generating evidence of absence of viral replication and transmission in pigs. The use of processing fluid (PF) was first described in 2018 in the United States and was demonstrated to provide a higher herd-level sensitivity compared with blood samples (BS) for PRRSV monitoring. In the meantime, data on vertical transmission of MLV viruses are rare even as it is a major concern. Therefore, veterinarians usually wait for several weeks after a sow mass vaccination before starting a stability monitoring. This clinical study was conducted in a PRRSV-stable commercial 1000-sow breed-to-wean farm. This farm suffered from a PRRS outbreak in January 2018. After implementing a stabilisation protocol, this farm was controlled as stable for more than 9 months before the beginning of the study. PF and BS at weaning were collected in four consecutive batches born after a booster sow mass MLV vaccination. We failed to detect PRRSV by qPCR on PF and BS collected in a positive-stable breeding herd after vaccination with ReproCyc® PRRS EU (Boehringer Ingelheim, Ingelheim, Germany).
