Turki & WinnickiMilking variables in relation to teatspreparation and unit attachmentdelay in cowsH. Turki & S. WinnickiVeterinarian Department – Agricultural University of Poznan,60-625 Poznan, 52 Wojska Polskiego streetE-mail: h_turki@hotmail.comMilking routines observations were carried out on 84 black and white dairycows randomly chosen. The effect of the time taken to manually stimulatethe teats (cleaning and drying) before the unit is attached “prep-time”divided into two classes (to 30 and >30 seconds) and the time delay fromthe beginning of the cow preparation process until unit attachment“prep-lag time” also divided into two classes (to 60 and >60 seconds) onmilk flow time, total milking time, first minute milk flow rate, averagemilk flow rate, milk yield and somatic cell counts in milk was investigated.The longest milk flow time was observed in rear teats, for all classes ofprep-time and prep-lag time. The greatest difference (P≤0.05) betweenfront and rear teats was observed for a prep-time and a prep-lag timerespectively of 30 and 60 sec.SummaryPrep-time had a significant effect on milk flow time (P≤0.01), total milkingtime (P≤0.01) and first minute milk flow rate (P≤0.01), this effect was alsoobserved on average milk flow rate (P≤0.05). However no significant effectswere observed on milk yield and somatic cell counts. Total milking time,first minute milk flow rate, average milk flow rate and milk yield decreasedas prep-lag time increased. Milk yield was influenced by prep-lag time(P≤0.05). No significant effects of neither prep-time nor prep-lag time wasobserved on somatic cell count in milk.Key words: Prep-time, prep-lag time, dairy cow, milk flow rate, milking time.To withdraw milk efficiently from the bovine mammary gland, the cowmust be included as an active partner in the milking process by evokingthe milk ejection reflex (Hamann, 1991). Studies have shown that milkejection is not entirely dependant on the action of oxytocin and that thereare also many other factors that control the effectiveness of oxytocinIntroductionICAR Technical Series - No 789
