Table 3a Interaction of cluster type and pulsation pattern on teat tissue changes (mm), mean milk yield (kg) and mean milking time (seconds) with low-level milking - Experiment 3

From: Effect of liner design, pulsator setting, and vacuum level on bovine teat tissue changes and milking characteristics as measured by ultrasonography
