French goat milk has shown a constant and significant increase in SCC since 1995. This increment could be explained by numerous factors, including increasing adoption of simplified management methods (e.g., once a day milking and extended lactation); insufficient genetic selection of goats for important traits (e.g., mastitis resistance, milk flow rate, udder and teat morphology); and the fact that milking equipment and settings (e.g., automatic cluster remover feature and teat cup liners) are not well designed to fit teat morphology in goats. To help address these problems, our studies focused on the animal-machine interaction, especially at the teat level. Milk flow kinetic recording (as milkability indicator) and teat-cup vacuum stability at different levels (by small devices such as VaDia) are basic techniques to evaluate efficiency of milking; however, these approaches do not include detailed teat characteristics. A “vacuometer” records the vacuum needed to open teat sphincters, which is highly correlated with milk flow, and could serve as a functional trait for selection. This information provides accurate use of vacuum levels to maintain teat tissue integrity. Ultrasonography is used to evaluate streak canal dimensions (associated with milk flow rate), and teat wall thickness, as well as teat congestion after milking; however, it is considered as an experimental approach. A “cutimeter” is a user-friendly caliper measuring teat tissue congestion by producers at the farm level. This method helps to evaluate machine settings impacts to better match teat traits along with liner design and its performance. Thermography is a more recent technology (initially expected to help in mastitis detection) that can be used to detect abnormal teat wall blood flow. Thermal imaging provides the possibility to evaluate teat-liner interactions at different parts of the teat. The 2D numeric imaging (typically used to evaluate udder morphological traits in small ruminant’s genetic selection schemes) is now being upgraded to 3D imaging, which is more accurate for evaluating teat morphology. Application of these new tools will help in measuring new traits and in the diagnosis of milking machine effects on teats and udder in dairy goats.
