    The objective of this study was to comparing first service conception rate before and after milking and changes in metabolite and hormones during four times realted to milking in lactating dairy cow. High producing Holstein cows (> 30 Kg/d and BCS) were randomlly selected and assigned into two groups: 1- insemination before morning milking (0700 a.m, n = 150) and 2- insemination after morni...

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...

The aim of this paper was to explore if, and in that case how, various preventive measures against mastitis influenced the whole-farm economic outcome, measured as technical efficiency, of a sample of specialised dairy farms in Sweden. In particular, the paper aimed at analysing whether a change to preventive measures applied by fully efficient farms would be a way for inefficient farms to beco...

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 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 ...
