  The objective of the study was to characterize profiles of phenotypic antimicrobial resistance of enteric bacteria from dairy cattle in different ages and management units. Feces were collected from Holstein and Jersey cattle in different management units on a large Central California dairy including hutch calves (pre-weaned), post-weaned heifers, breeding heifers, springer’s (pregnant nulliparous females due to calve), fresh (recently calved) uniparous (first lactation) cows, fresh multiparous (second or greater lactation) cows, mid-lactation multiparous cows, pregnant late lactation multiparous cows, far-off (recently) dry cows (non-lactating), close up (1-3 week due to calve) dry cows, hospital pen, and mid to late lactation multiparous cows. E. coli and Enterococcus were isolated from fecal samples from cattle in different management units and tested for su.. View More»
