13 pages., Article #: 3FEA2, via online journal., A multiple indicators, multiple causes, or MIMIC, modeling framework can be used for analyzing a variety of farmer decision-making situations where multiple outcomes are possible. Example applications include analyses of farmer use of multiple information sources, management practices, or technologies. We applied the framework to analyze use of multiple information sources by beef cattle farmers. We provide measures of how farmer demographics, farm characteristics, and risk attitudes influenced farmer use of information from Extension, producer groups, popular press, the U.S. Department of Agriculture, the Internet, and other farmers. Education and greater willingness to take risk positively influenced information use among the farmers we studied. Our process has implications for broader use within Extension.
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.
