Udder health is a key factor for dairy cows’ productivity and welfare. This study presents the first insight into udder after introduction of automatic milking systems in Greece. Four farms with Holstein cows enrolled study. Data from their records were utilized, January 2020 to December 2021. Variables employed assessment cow daily milk yield (DMY), number milkings / cow, individual somatic ce...

Data from 113 Dutch organic farms were analysed to determine the effect of cross-breeding on production and functional traits. In total, data on 33 788 lactations between January 2003 and February 2009 from 15 015 cows were available. Holstein-Friesian pure-bred cows produced most kg of milk in 305 days, but with the lowest percentages of fat and protein of all pure-bred cows in the data set. C...

Holstein Friesian cross bred cow milk samples of different quarters in four stages of lactation were collected from dairy farms in the Namakkal district of Tamil Nadu and analyzed for composition and somatic cell count (SCC). No significant difference in the SCC was observed between quarters within the lactation stage. Count was significant between stages of lactation after the 2 nd stage. Whil...

The aim of this study was to describe and analyze effects of parity, stage of lactation, milkability (3 groups of cows with differing peak flow rates), time of milking, and quarter position on milk production and milk flow measures at udder and quarter levels. Particular emphasis was put on changes to the decline phase and in duration of overmilking. More than 75,800 quarter milk flow curves an...

BACKGROUND The dairy industry has undergone substantial structural changes as intensive farming has developed during recent decades. Mastitis continues to be the most common production disease of dairy cows. Nationwide surveys of mastitis prevalence are useful in monitoring udder health of dairy herds and to study the impact of structural changes on the dairy industry. This survey on bovine sub...

In order to determine the possible effects of udder traits on milk yield and milk composition a serial of experiments were carried out on five different sheep farms, between 1998-2000. Ten breeds and genotypes were included in these experiments: Merino, (Merino x Pleven Blackhead) F1, Pleven F1 x Black East Friesian, Lacaune, (Merino x Lacaune) F1, British Milksheep, (Merino x British Milksheep...
