Optimization of Cow Milking Vacuum Regime

Abstract

Researches of lactating cows determined that milking with optimal vacuum regime of 45 kPa compared to 48 kPa let us raise daily milk yield of cows with per lactation productiveness rate of 3000-4000 kilos of milk at 0,7 kg or 5,4%, 4000-5000 kilos - at 0,6 kg or 3,6%, 5000-6000 kilos - at 1,2 kg or 5,6%, fat contents - at 0,17; 0,26 and 0,15% accordingly. The quantity of cows with udder irritation decreased at 12,5%. Economic effect during the research period (120 days) counted 65892 rubles per cow (549 rubles per day).
