Lactating Dairy Cattle

Abstract Both the economic loss and welfare implications of lameness vastly impact the dairy industry. There is a need for effective modalities of analgesia to minimize welfare concerns regarding lameness associated pain in lactating dairy cattle. To date, there are no labeled products with pain control indications available for lactating dairy cattle in the United States. Non-steroidal anti-inflammatory drugs (NSAIDs), like meloxicam and flunixin meglumine, are commonly used by veterinarians for pain management. Data is limited as to their efficacy in lameness-associated pain management. The overarching goal of this study was to compare the analgesic effects of flunixin meglumine (IV) and meloxicam (PO) in lactating dairy cattle with experimentally induced lameness via intra-articular injection of amphotericin B. We hypothesized that lameness would improve under meloxicam treatment compared to flunixin meglumine or no treatment control. A double blinded, randomized controlled trial involving positive and negative controls created the framework to assess efficacy parameters. Parameters included pressure algometry, pressure mat analysis, lameness score, infrared thermography imaging, substance P, and cortisol concentrations of 48 lactating Holstein cows across a six-day time period. Intra-articular injection with amphotericin B resulted in mild transient lameness. Results indicated statistically significant treatment by time effects for several parameters. Visual lameness scores showed flunixin meglumine was equally effective to meloxicam and both more effective than the positive control (P < 0.0001). Flunixin meglumine administered animals displayed lower cortisol levels to that of meloxicam treated cows and both more effective than the positive control (P = 0.0008). The cows treated with meloxicam withstood a greater force created by mechanical nociception threshold than cows administered flunixin meglumine and both more effective than the positive control (P = 0.0008). The impact of NSAID use as a therapeutic treatment of lameness is insurmountable in combatting welfare concerns in the dairy industry.

Lactating Dairy Cattle

AbstractA systematic review and network meta-analysis were conducted to assess the relative efficacy of antimicrobial therapy for clinical mastitis in lactating dairy cattle. Controlled trials in lactating dairy cattle with natural disease exposure were eligible if they compared an antimicrobial treatment to a non-treated control, placebo, or a different antimicrobial, for the treatment of clinical mastitis, and assessed clinical or bacteriologic cure. Potential for bias was assessed using a modified Cochrane Risk of Bias 2.0 tool. From 14775 initially identified records, 54 trials were assessed as eligible. Networks were established for bacteriologic cure by bacterial species group, and clinical cure. Disparate networks among bacteriologic cures precluded meta-analysis. Network meta-analysis was conducted for trials assessing clinical cure, but lack of precision of point estimates resulted in wide credibility intervals for all treatments, with no definitive conclusions regarding relative efficacy. Consideration of network geometry can inform future research to increase the utility of current and previous work. Replication of intervention arms and consideration of connection to existing networks would improve the future ability to determine relative efficacy. Challenges in the evaluation of bias in primary research stemmed from a lack of reporting. Consideration of reporting guidelines would also improve the utility of future research.

The Impact

Psycholinguistic research into metaphor processing is burdened with empirical problems as experiments provide diverging evidence on the impact of conventionality, familiarity and aptness, and with conceptual issues as the interpretation and operationalization of the three concepts mentioned, as well as the related predictions which can be drawn from theories of metaphor processing, are controversial in the literature. This paper uses tools of statistical meta-analysis in order to bring us closer to the solution of these problems and reveal future lines of research.
