Abstract

Intramammary infections (IMI) are prevalent in nonlactating dairy cattle and are known to alter mammary structure and negatively affect the amount of mammary epithelium in the gland. Mechanisms responsible for the observed changes in mammary growth during an IMI are poorly understood, yet the...

Abstract

Intramammary infections (IMI) are prevalent in non-lactating dairy cattle and their occurrence during periods of significant mammary growth and development (i.e. pregnant heifers and dry cows) is believed to interfere with growth, development, and subsequent milk production. However, direct study...

Abstract

This investigation evaluated the efficacy of a bacterin in reducing the prevalence of staphylococcal mastitis and somatic cell counts (SCC) in a dairy goat herd. Does were vaccinated or left as controls, and the levels of mastitis and SCC monitored over 18 months. Staphylococcus caprae (42.5%), S....

Abstract

Staphylococcus aureus remains a major mastitis-causing pathogen in growing dairy heifers, resulting in damage to developing milk secretory tissue. The purpose of this study was to evaluate the role of horn flies as vectors in the spread of S. aureus among dairy heifers immunized with a S. aureus...

Abstract

Initial studies in Louisiana, USA to determine the prevalence of mastitis in breeding age dairy heifers demonstrated that intramammary infections (IMIs) were present in 97% of heifers and 75% of quarters. Most common isolates were Staphylococcus aureus, Staphylococcus hyicus, and Staphylococcus...

Abstract

The purpose of this study was to evaluate the effect of a feed additive (OmniGen-AF®, reported to have immune modulating activity) on innate immunity and health events during the periparturient period in dairy heifers when immunity is suppressed. From 60 days prepartum through calving, supplemented ...
