Randomized controlled field trial comparing quarter and cow level selective dry cow treatment using the California Mastitis Test

Cow- and quarter-level risk factors for Streptococcus uberis and Staphylococcus aureus mastitis.

This study was designed to identify risk factors for intramammary infections with Streptococcus uberis and Staphylococcus aureus under field conditions. An 18-mo survey with sampling of all quarters of all lactating cows at 3-wk intervals was carried out in three Dutch dairy herds with medium bulk milk somatic cell count (200,000 to 300,000 cells/ml). Quarter milk samples were used for bacterio...

Mastitis Prevention and Cure Rates in Heifers Treated with Spectramast Dry Cow Therapy and/or Orbeseal Dry Cow Teat Sealant

Dairy cows are vital for milk production, cheese, cream, and so much more. Healthy udders and teats are necessary to keep production levels at their highest and to keep the number of cows being culled to the lowest levels. Inflammation of the mammary gland is called mastitis, which is typically caused by bacteria that invade the teat canal. This disease is most often transmitted by contact with...

Control of Mastitis through dry cow therapy: A review

Introduction Mastitis is one of the most economically important diseases of milch animals and also causes the changes in glandular tissues affecting quality and quantity of milk [1]. Mastitis continues to be the most costly disease of dairy animals. Field surveys of major livestock diseases in Pakistan have ranked mastitis as number one disease of dairy animals [2,3]. In Nili-Ravi buffaloes, ma...

Randomized noninferiority study evaluating the efficacy of 2 commercial dry cow mastitis formulations.

The study objective was to compare the efficacy of 2 commercial dry cow mastitis formulations containing cloxacillin benzathine or ceftiofur hydrochloride. Quarter-level outcomes included prevalence of intramammary infection (IMI) postcalving, risk for cure of preexisting infections, risk for acquiring a new IMI during the dry period, and risk for clinical mastitis between dry off and 100 d in ...
