Milking variables in relation to teatsachieve either adequate teat sanitation or consistent milk letdown stimulus.No significant effects of neither prep-time nor prep-lag time was observedon somatic cell count in milk.ConclusionAverage milk flow time increased significantly in all quarters (P≤0.01) asprep time increased, on the other hand no significant effect of prep-lagtime was observed on milk flow time. The longest milk flow time wasobserved in rear teats, for all classes of prep-time and prep-lag time.First minute milk flow rate and average milk flow rate were influenced byprep-time and prep-lag time. As prep-time and prep-lag time increased,first minute milk flow rate and average milk flow rate decreased.Milk yield was not affected by prep-time, however it was influencedsignificantly by prep-lag time.Total milking time increased as prep-time increased and decreased asprep-lag time increased. The longest total milking time was observed for aprep-time and a prep lag-time respectively over 30 sec. and ranging from0 to 60 sec.No significant effects of neither prep-time nor prep-lag time was observedon somatic cell count in milk.ReferencesBruckmaier RM, Blum JW. 1996.
