Udder health in relation to udder and teat morphometry in Holstein Friesian × Sahiwal crossbred dairy cows

摘要: The present investigation involved 261 Holstein Friesian (HF) × Sahiwal cows to study the udder health as well and teat morphometry. was defined on basis of bacteriology California mastitis test quarter foremilk. morphometry parameters included fore depth (UFD, distance from point where merges within abdomen a in front teats at level base), rear (URD, bottom vulva base udder), (UD, with respect hock joint), height floor, length, diameter (at mid barrel), teat-tip floor between teats. URD, UD showed significant (P < 0.05) relation mastitic having larger smaller placed below joint. length than 4.5 cm 3.0 or had significantly more quarters affected mastitis. Further, nearer were susceptible 0.01). No differences found healthy udders UFD It can be concluded that selection for optimum breeding programmes may help reduce susceptibility intramammary infections HF cows.
