________________________________________________________________________________ Abstract Udder health considerably affects the economics of dairy farming. There are different reasons for poor udder health; one of them is the milking technique. In earlier studies it was shown that automatic milking systems (AMS) have advantages over conventional milking systems (CMS). Quarter individual milking...

The primary objective of premilking udder preparation and teats antiseptic is to achieve an acceptable level of decontamination of teat skin. This aids in reducing the spread of microorganisms and incidence of new intramammary infections, and in minimising the number of bacteria. The aim of our studies was to investigate the influence of pre-milking teat antiseptic solutions on total bacterial ...

Milk flow parameters at udder and quarter levels were studied in relation to somatic cell count (SCC) and other risk factors for mastitis (bimodality, duration of decline, and duration of overmilking phase). Thirty-eight Holstein cows in their first to sixth lactations were investigated during 10 mo of lactation. Monthly milk samples were collected for SCC during morning milking. Quarter and ud...

The current study was planned to investigate the potential risk factors and their association with mastitis in Cholistani cattle. For this purpose milk samples were collected and examined for mastitis using California Mastitis Test. The results showed an overall 21.96% prevalence of subclinical mastitis. The analysis of variance did not show significant association of tail size, live body weigh...

In this article the use of somatic cell counts for monitoring udder health and milk quality is discussed. Somatic cell count dynamics at quarter, cow, herd and population level are discussed and illustrated with examples. Quarter and cow somatic cell counts directly represent the inflammatory status of the mammary gland. Herd and population somatic cell count are related to the inflammatory pro...

This article examines the relationship between shape, size and of udder Bushuev cows on different categories farms their milk yield. It was determined that yield belonging to form bowl-shaped in all higher from 720.9 kg 641.8 than peers round udder. In comparison, with a cup-shaped 3.3 cm 2.2 wider, length 9.1 7.8 longer, circumference 6.3 8.7 bigger, depth 1.6 2.7 nipple diameter 0.06 0.35 cm,...

BACKGROUND Studies outside the Nordic countries have indicated that subclinical mastitis (measured by milk somatic cell count or the California Mastitis Test), intramammary infections (IMI), or blind quarters in beef cows may have negative effects on beef calf growth. Knowledge on prevalence of such udder health problems in Swedish beef cows is scarce. Therefore, the main aim of this study was ...

Analysis was made of the relationship between conformation traits and lifetime production efficiency of the cows that first calved in 2000 and represented the active population in the Pomorze and Kujawy regions of Poland. The CORR Pearson procedures of SAS package were used in the statistical calculations. It was found that there is a statistically significant relationship, weak or low on the G...

To determine whether tail docking would influence cow cleanliness and udder health in a free-stall system, we monitored milking cows after half the animals in a herd were docked. A sample of 223 docked and 190 undocked cows (reducing to 169 and 105 over the study as cows were dried off) were monitored for 8 wk. Cow cleanliness was scored in two areas: along the spine, and the rump adjacent to t...

The present study was performed to study the genetic relationship of productive life with production and type traits of Korean Holsteins at first three lactations. The data for the analysis from 56,054, 28,997, and 11,816 animals of first, second and third parity cows which were born from 2006 to 2011 were collected by Dairy Cattle Improvement Center, National Agricultural Co-operative Federati...
