Traditionally, pre-milking stimulation on dairy farms has been provided by hand: application of a pre-milking disinfectant to teats, stripping of the teat cistern using the fingertips, and a towel wipe of the teat barrels and ends prior to placement of the machine. With the advancement of milking technology and a particular need to maintain consistency in a dairy facility’s milking routine, forms of pre-milking stimulation through non-manual systems have been developed. However, adequate udder stimulation prior to milking remains to be a critical step essential for milk letdown and failure to accommodate the physiological requirements to elicit a proper milk-ejection reflex can result in reduced milk production, longer milking duration, and impacts on udder health. Additionally, adverse musculoskeletal outcomes are prevalent among dairy workers and repetitive tasks including pre-milking preparation of the udder are reported to be among the most physically demanding tasks on a dairy facility. This can contribute to inconsistency in technicians’ work; these findings along with the importance of effective pre-milking stimulation creates a need for finding more automated biotechnological solutions for teat preparation. Our hypothesis is that we can achieve an appropriate and efficient milk letdown using a nonmanual novel stimulation method, such as that supplied by the Udderways device. The device is a wand that uses a vortex of air and sanitizing solution to stimulate, clean and dry the teats. Our objective is to evaluate the efficacy and ability of this device to provide the physiological requirements that maximize milking performance and produce equivalent udder health to a traditional miking routine. Thereby, a randomized controlled clinical trial will be performed on a dairy NY Farm to (1) determine the ability of the device to provide improved pre-milking stimulation and (2) evaluate the impact on udder health. Treatment will consist of pre-milking stimulation, cleaning, and drying provided solely by the Udderways device. Cows in the control group will receive traditional manual pre-milking stimulation, cleaning and drying. Data on milk yield, average milk flow, milking duration, somatic cell count, and clinical mastitis incidence will be obtained. We will use multivariable generalized linear regression models to determine the effect of the novel stimulation on the selected outcome variables.
