Kentjonowaty, I., P. Trisunuwati, T. Susilawati, P. Surjowardojo


Objectives of the research were to study different long time mammae hand massage o n milk production dairy cattle. The hand massages pressure mammae 1 - 1.6 equivalent to volt to measure by piezoelectric sensor PVDF Film as a standard. The function of mammae massage should usual is stimulated pituitary posterior impact release oxytocin hormone.  Serves to contraction myoepithel cells lining the alveolus could result in milk ejection.  Materials research twelve dairy cows Fries Holland crossbreed; purposive sampling was used in taking samples. The research Method used was the experimentation with using Randomized Block Design.  Block by duration of lactation is the early lactation (1-3 months), mid lactation (4-6 months) and late lactation (7-9 months). The treatments were no massage, massage 20, 50 and 80 seconds. Before the implementation of milking, milking preparation done by means of mammae massage a pressure massage 1 - 1.6 equivalents to volt and have interval between the finish mammae massage with the implementation of milking 90 seconds.  The result of the research showed that on block: early lactation = 13,75±1,45 liter liter a, mid lactation = 12,83±1,52 liter a and late lactation = 7,60±1,21 liter b, and on Treatment no massage = 9,84±2,92 liter a; massage for 20 seconds = 11,65±3,40 liter ab; massage for 50 seconds = 13,08±3,38 liter bc and massage for 80 seconds = 11.01±3,60 liter a.  Based on the statistical analysis, the treatment had a significant effect on the amount of milk production (P < 0,1).   It is concluded to the best method is to massage for massage 50 seconds with a pressure massage 1 - 1.6 equivalent to one volt and an interval between the finish of the mammae massage with the implementation of milking to 90 seconds.
