To estimate herd prevalence of Salmonella spp, fecal specimens were obtained for culture from neonatal calves of 47 Ohio dairy herds. Of the 452 calves tested, 10 calves from 7 farms were culture-positive. Salmonella serotypes isolated were S dublin, S typhimurium, S enteritidis, S agona, S mbandaka...

During the period Nov. 1977 to Nov. 1979, 5 herds with high Wisconsin Mastitis Test (WMT) scores (>=16 mm) were studied. At the beginning of the trial, herds were visited by the authors, practices used on the farms were evaluated, and recommendations were made for correction of any deficiencies i...

Dairy herds in Ohio were selected by stratified random sampling for participation in a disease-monitoring study to relate Streptococcus agalactiae intramammary prevalence to herd management and environmental conditions. Of 48 herds studied, 27 herds had at least 1 cow infected with this pathogen. Ma...

Nine commercial dairy herds, each with low herd milk somatic cell counts, were monitored for 1 yr to determine prevalence of intramammary infections and rates of clinical mastitis. Staphylococcus species was the bacterial group most frequently isolated from quarters at calving and at drying off. Env...

144 dairy cows of 5 breeds with a total of 184 parturitions were assigned randomly by breed and parity to a reproductive herd health programme or a control group for 2 yr. Animals of the herd health programme averaged 1.85, 1.73, 73.1, and 99.24 resp. for number of inseminations, inseminations/conce...

A 6-month trial was carried out on the comparative effects of lactation therapy (systemic and intramammary), early drying off followed by dry-cow therapy, and culling based on milk somatic cell count (SCC), on mastitis incidence in a 124-cow herd. In the 6 months prior to the trial, between 14.6 and...

A stratified-random sample of 48 Ohio dairy herds participated in a 1-year disease monitoring survey to study herd management and environmental conditions affecting udder infection and clinical mastitis incidence. The mean monthly bulk-tank somatic cell count was used as an indicator of overall udde...

Eleven dairy replacement heifers (mean body weight 262 kg) were given two treatments with levamisole in the spring, 3 and 6 weeks after they had been moved from confinement to permanent pastures, at which time they were 5 to 12 months old. Treated heifers gained more weight than a group of 11 contro...

Dairy replacement heifers given two strategic treatments with ivermectin (0.2 mg/kg) three and eight weeks after turnout to spring pastures in northern USA (Ohio) had mean adjusted weight gains (62.3 kg) that were 62% greater than those of control heifers (38.5 kg) at the time of winter housing. Pas...

A stratified random sample of 50 Ohio dairy herds, monitored for 1 year between March 1988 and May 1989, was used to estimate the component costs of clinical mastitis per cow-year overall and by organism, the component costs of an episode of clinical mastitis overall and by organism, and the inciden...

The use of a single tank milk culture and a single milk filter culture was studied for their suitability as screening tests for coagulase-positive staphylococci and Streptococcus agalactiae. Bulk tank and bulk tank milk filter cultures were compared with quarter milk cultures taken from individual c...

The effectiveness of 2 levels of educational effort on adoption of mastitis control procedures was studied in 43 herds with persistently high Wisconsin Mastitis Test scores. A teat dipping and dry cow therapy programme was adopted by more herds in the group on the higher level of educational effort,...

The design of horse housing for improved animal health and veterinary access is described. Free stalls are used for feeding and for palpation. Floor surfaces of ground limestone, clay, 3/4 inch gravel and asphalt are used. Low cost palpation stalls are used for safe work with mares..

A simple procedure that can be used by veterinary practitioners for identification of mastitis pathogens is outlined. It consists of using plates of blood agar or 2 selective agars (TK/FC and MacConkey), the catalase test and Gram staining to identify major udder pathogens in milk samples. When the ...
