7 pages., via online journal, There are approximately 65 dairy farms in Mississippi (Gregory, 2019) with an estimated annual milk value of $26 million (Mississippi Farm Bureau, n.d.). Mastitis is the most expensive disease in the dairy industry (Neeser, Hueston, Godden, & Bey, 2006) and can decrease milk production by 1,181 kg per lactation in multiparous cows (Wilson et al., 2004). Clinical mastitis accounts for the largest use of antibiotics in livestock species (Thomson, Rantala, Hautala, Pyörälä, & Kaartinen, 2008), a circumstance that raises concerns of antimicrobial resistance (Pol & Ruegg, 2007; Wang et al., 2015) and increases producer expenses due to purchasing antibiotics and discarding milk during treatment (Rollin, Dhuyvetter, & Overton, 2015). On-farm bacteriological culturing (OFBC) enables producers to distinguish among broad categories of microorganisms with great accuracy and provides results within 24 hr, versus approximately a week when cultures are sent to a laboratory (Down, Bradley, Breen, & Green, 2017). Despite the availability of several viable OFBC systems, adoption of OFBC in Mississippi has been limited.
The purpose of the study reported here was to implement and evaluate an OFBC pilot test with a small sample of Mississippi dairy producers. The objectives of the study were
to identify reasons for producers' lack of OFBC adoption,
to explore change in producers' knowledge and perceptions of OFBC before and after trial, and
to assess the effectiveness of an Extension-led trialing program relative to OFBC adoption.

9 pages., via online journal, Our multistate group of state horse specialists produced and evaluated impacts from six webinars and online short courses (webinar plus additional content) addressing current industry issues: pasture-associated laminitis, equine herpesvirus-1, disaster preparedness, sales fraud, rescues/rehoming, and manure management. We identified no differences in perceived knowledge gained from webinars or short courses; however, results suggest that participation in short courses versus live webinars may be more useful for making positive management decisions. Short course participants also reported greater potential for cost savings as a result of completing the education. On the basis of the study, we offer recommendations for developing effective online Extension education programs.
