108 milk samples were collected to study the relationship of somatic cell counts (SCC) and milk composition with milking methods and udder hygiene from 27 Holstein Frisian (HF) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at Khyber Pakhtunkhwa Agricultural University Peshawar dairy farm. All animals were randomly distributed into three categories on the basis of ...

genetic and phenotypic parameters related to production traits, udder conformation and somatic cell count for the iranian holstein cows were estimated. monthly records of somatic cell counts (scc) were primarily transformed into somatic cell scores (scs) and the the average level of lactation period, with correction for milk volume, was calculated. by use of these estimates an udder health inde...

Mark, T. 2005. International Genetic Evaluations for Udder Health Traits in Dairy Cattle. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-6992-9 The aim of this thesis was to investigate different approaches for international genetic evaluations of dairy sires for udder health traits. For this purpose, deregressed national genetic evaluations were used of Holstein milk somatic cell (SC) from...

It was established by Shaw and Knodt (I) that the normal lactating udder (in situ) of the cow utilizes almost 2 mg. of phydroxybutyric acid per 100 ml. of blood traversing the udder; it was calculated that this was sufficient to account for the short chain fatty acids of milk fat or for about 40 per cent of the oxygen consumption of the secreting gland if it were oxidized for energy purposes. L...

Udder Injuries often reduces the milk yield and the sustainability of economic returns. Ultrasonography was deployed to study the nature and number of  stulous tract, which developed as a consequence to mid gestational teat injury in afourth parity Jersey crossbred.Teat ultrasonography revealed the discontinuity of teat wall with a singular  stular tract on the lower one third of the left for...

Udder cleft dermatitis (UCD) is a common skin problem in dairy cows, localized at the fore udder attachment or between halves. The main objectives of this study were to investigate spontaneous recovery from UCD longitudinal and treatment effect on topical spray containing chelated copper zinc an additional trial. Spontaneous was investigated during 1-yr which 7 Swedish herds visited 9 times eac...

The objective of this study was to determine the relationships among daughter clinical mastitis during first and second lactations and sire transmitting abilities for somatic cell score, udder type traits, productive life, and protein yield. Data on clinical mastitis during first lactation were available for 1795 daughters (in six Pennsylvania herds, one Minnesota herd, and one Nebraska herd) o...
