8 pages, Cattle handling Extension program educators often overlook the animal training component of efficient handling. The objectives of the study described in this article were to measure young dairy heifer behavioral responses toward handlers who received different types of training and to document whether repeated handling or time of day of handling affected heifer behavioral responses to handlers. Six handlers received training through a lecture, hands-on workshop, or video. An observer recorded heifer behavior during handling tests. The day and time of heifer training were most influential on heifer behavior, but heifer handling ease was improved when handlers had participated in the hands-on training.
26 pages, Proper calf care is important on dairy farms as management practices affect animal well-being and productivity as well as farm profitability. This article highlights areas of calf management needing improvement according to the results of a mixed-mode survey intended to provide a snapshot of calf management practices in Vermont. Areas for which improvement is needed aligned with farmers' identification of topics of interest and included calving management, nutrition (particularly neonatal feeding practices), and biosecurity (including vaccination). Extension professionals can draw on information about practices needing improvement and topics of interest to farmers to better position themselves to provide outreach tailored to the real and perceived needs of their clients.
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.
7 pages, On-farm bacteriologic culturing (OFBC) provides quick and inexpensive mastitis diagnosis, but commercial adoption of this innovation has been low in Mississippi. We implemented an Extension-led trialing program to identify reasons for producers' lack of OFBC adoption, explore change in producers' knowledge and perceptions of OFBC, and assess the effectiveness of the program relative to OFBC adoption. Most producers were unaware of OFBC initially but identified several benefits after trialing it for 30 days. The methodology for designing and implementing a trialing program based on Rogers's diffusion of innovation framework was effective and could be replicated easily in other contexts.
