Present study was undertaken to compare the effect of two different milking methods (hand vs. machine milking) on milking ability in Murrah buffaloes and Sahiwal cows. 30 lactating Sahiwal cows and 30 lactating Murrah Buffaloes were selected and divided into four equal groups having 15 animals each. 15 animals of each species were subjected to machine milking and 15 animals of each species were...

In robotic milking there is always a slight chance of failure to attach the milking cluster. Attachment failure is most likely for cows whose udder conformation is less convenient for robot attachment. In general, after milking failure cows try to revisit the milking robot if they are not sent to a separate area. Since it is difficult to estimate the effect of milking failure on such a cow and ...

The aim ot the study was to examine the effect of morphine and naloxone pretreatment on cortisol and ACTH concentrations in response to machine milking in dairy cows. In the first part of the experiment, the effects of i.v. morphine doses (0, 21, 70 and 210 mg, one dose each day) 10 min before morning milking were studied in six Brown Swiss dairy cows. In the second part, four cows were treated...

Few studies have been developed to evaluate the differences of bovine mastitis situation between hand and machine milking under the American tropic conditions. Twenty dairy herds were studied, 11 using hand milking (HM) and 9 machine milking (MM), from «San José de las Lajas» municipality, Mayabeque province. Between May 2009 and March 2012, samples from 182 cows (113 MM and 69 HM) were obtaine...

The aim of this present study is to describe changes occurring during the milking of cows in various periods following the introduction of an AMS (automatic milking system). The following cow milking parameters were analysed: milkings per cow per day, milking yield, milking speed and milking duration. An increase in milk yield in AMS barns has been found to be possible, but it is affected by a ...

AIM The present study was undertaken with the objective to obtain insight into the dynamics of the release of β-endorphin, adrenocorticotrophic hormone (ACTH) and cortisol in response to machine milking in dairy cows. MATERIALS AND METHODS A total of 10 healthy multiparous lactating Italian Friesian dairy cows were used in the study. Animals were at the 4(th)-5(th) month of pregnancy and were...

The aim of this study was to analyse whether automatic milking has an effect on reproduction in dairy cows. Probably the most important consequence of automatic milking is an increased milking frequency. More frequent milking means more production and thereby an extra threat for the energy balance during the first months of lactation. A deep negative energy balance (NEB) is often followed by ne...
