: Friesian-type dairy cows were milked with different machine settings to determine the effect of these settings on teat tissue reaction and on milking characteristics. Three teat-cup liner designs were used with varying upper barrel dimensions (wide-bore WB = 31.6 mm; narrow-bore NB = 21.0 mm; narrow-bore NB1 = 25.0 mm). These liners were tested with alternate and simultaneous pulsation patter...

Milk yield, milk flow, and udder morphology traits were measured in 72 East Friesian crossbred multiparous ewes to estimate the variation in milk flow patterns present in this research flock, and to asses the repeatability of these measurements and their relationships with other lactation traits. A special milk flow apparatus designed for dairy ewes was used on two consecutive morning milkings ...

The technique of perfusion of the isolated udder is likely to give valuable information on the mechanisms of milk formation, provided it can be shown that most of the milk collected is actually a product of the secretory activity of the gland during the experiment. This point is not easy to demonstrate by ordinary chemical methods, because present-day techniques only permit of a rather limited ...

Release of oxytocin (OT) is essential for milk ejection in dairy cows (Lefcourt & Akers, 1983; Bruckmaier & Blum, 1998). During milk ejection, alveolar milk is shifted into the cistern, which causes an increase of intracisternal pressure (Bruckmaier et al. 1994). To initiate maximum milk ejection at the start of milking, increasing OT concentration beyond a threshold level is sufficient (Schams...

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 ...

  Background : Since milk is considered as one of the most common foods in human life, this research aimed to evaluate the quality of milk produced in traditional and industrial dairy farms of Yazd province in 2007.   Materials and Methods : In this descriptive study, six farms were selected in the cities Sadoogh, Yazd and Mehriz and sampling was performed in each of them bimonthly...
