Determination of the need for stimulation in East German Black Pied, Simmental, Jersey, Holstein-Friesian and Holstein-Friesian X zebu cows using dose-effect regressions of alveolar milk ejection (y) on duration of stimulation (x)



Determination of the need for stimulation in East German Black Pied, Simmental, Jersey, Holstein-Friesian and Holstein-Friesian X zebu cows using dose-effect regressions of alveolar milk ejection (y) on duration of stimulation (x)



Wissenschaftliche Zeitschrift der Karl Marx Universitat Leipzig, Mathematisch Naturwissenschaftliche Reihe 35(3): 283-291



The need for stimulation before milking was determined for 6 groups of cows (3 in the German Democratic Republic and 3 in Cuba) by applying teatcups to 3 teats for 15, 45, 150 and 300 s at both the morning and the evening milkings, without previously touching the udder.
