چکیده
Preparing cows for milking is one of the most important operations. Not only speed milk production but also quality depends on level work performed.
 One effective ways to mechanize preparation implies development a special mechanical brush that cleans and stimulates teat skin. As result, there no need use additional foam detergents napkins cleanse disinfect teats.
 A device has been designed cleansing teats with two rotating brushes.
 Theoretical studies interaction elements removal pollutants from udder in course operation were carried out. Assuming constancy modulus elasticity, shape roughness teats, linear angular velocities brushes, nap stiffness, homogeneity physical properties contaminants teat, dependence force Fe length l element its ? was established. Under condition smaller than Fp which causes pain greater retaining (adhesion), values main design technological parameters developed determined: l=8 mm, ?=106 rpm.
 result tests, it found when using device, daily yield experimental group exceeded control by an average 1.1 times made possible obtain supplement 132.5 kg milk. Along this, 0.19 % increase fat content compared group. The number microorganisms decreased 2.2 contaminant particles 4.6

Infection of the mammary gland with environmental bacterial pathogens is the most significant udder health problem facing the dairy industry in North America. Forty years ago, Neave et al. (1966) stated that the rate of new intra-mammary infection is related to the number of bacteria that the teat end is exposed to, and several studies have made associations between clean housing, clean cows an...

Introduction Maintaining consumers trust is essential to ensure the future of the dairy industry. Production of high quality milk from healthy, well cared for animals is the goal of most dairy farmers. However, as fewer and fewer consumers are familiar with dairy farming, they have become more skeptical about the ability of farmers to properly care for farm animals. Public attention about the w...
