Relationship of early first lactation somatic cell count with risk of subsequent first clinical mastitis
The relationship between initial Somatic Cell Count (SCC) and time to first clinical mastitis was estimated from data including 20,422 Holstein heifers, without clinical signs of mastitis during the first month of lactation and with a first test day SCC lower than 400,000 cells /ml. Number of days from 35 days after first calving to first clinical mastitis event in first or second lactation was...
متن کاملDifferential leukocyte count method for bovine low somatic cell count milk.
Whereas many differential leukocyte count methods for high somatic cell count (SCC) milk from mastitic cows are available, only a few have been developed for low SCC milk. We have developed a flow cytometric differential leukocyte count method for low SCC milk. The procedure consists of 1) 1.5 ml of diluted milk sample (30%, vol/vol dilution with PBS), 2) centrifugation, 3) leukocyte labeling w...
متن کاملGenetic Parameter Estimates for Lactation Curve Parameters, Milk Yield, Age at First Calving, Calving Interval and Somatic Cell Count in Holstein Cows
The objective of this study was to estimates the genetic and environmental components for the lactation curve parameters, milk yield, age at first calving (AFC), calving interval (CI) and somatic cell count (SCC) in Iranian Holstein cows. The dataset consisted of 210625 test day records from 25883 cows with milk yield in the first parity recorded from July 2002 to September 2007 in a total of 9...
متن کاملI-14: Assisted Reproduction and Religion What Consideration Should Be and Should Not Be Relevant,
Several important issues are pertinent to an ethical discussion of the new technology today grouped under the name Assisted Reproduction Technology (ART). This is a moral imperative because each of us must decide what is to be considered ethically acceptable in assisted reproduction. Reflecting on the ethical dimension of ‘creating’ a new human life can play a major role in ensuring that in eac...
متن کاملDifferential leukocyte count: manual or automated, what should it be?
Today's automated hematology analyzers capable of performing a full CBC and a differential leukocyte count (DLC) on whole blood, particularly in a closed tube system, using cytochemistry or impedance-based flow cytometry technology coupled with laser light scattering, conductivity and/or differential cell lysis, are here to stay. Their need and popularity among at least the large, cost and qual...
