Efficacy of intramammary antibiotic therapy for treatment of clinical mastitis caused by environmental pathogens.
TLDR
Clinical cure rates did not differ when quarters were grouped by etiology, but clinical cure rates for quarters with pathogens other than streptococci or coliforms were lower in group O. Expand
Prevalence of Salmonella spp in selected birds captured on California dairies.
TLDR
Birds that commonly inhabit California dairies harbor Salmonella organisms, but because of the low prevalence of Salmonello organisms in birds and theSalmonella serotypes isolated, birds are not important reservoirs of Salbornella organisms on California d dairy farms. Expand
Type of cottonseed and level of gossypol in diets of lactating dairy cows: plasma gossypol, health, and reproductive performance.
TLDR
Consumption of a high gossypol diet for 170 d had no effect on health of lactating dairy cows, but it increased PG concentrations and impaired reproductive performance, and the probability of conception after the first artificial insemination declined at a decreasing rate as the plasma TG increased.

Efficacy of a Dried Colostrum Powder in the Prevention of Disease in Neonatal Holstein Calves
TLDR
Calves fed 85g of the dried colostrum powder dissolved in 3kg of whole milk had significantly lower IgG concentrations 24h after birth than calves of the other groups and Morbidity and mortality rates were not significantly different among groups. Expand
Antimicrobial susceptibility of microorganisms isolated from the mammary glands of dairy heifers.
TLDR
Results indicated that the majority of staphylococcal strains were susceptible to the antimicrobial agents tested but that antimicrobial susceptibility varied for Streptococcus sp. Expand
Bacteriological culture of blood from critically ill neonatal calves.
TLDR
Results of this study support the need to address the failure of passive transfer of maternal antibodies to prevent bacteremia in calves and describe the variety of bacteria involved. Expand
Relationships between Maternal and Fetal Liver Copper, Iron, Manganese, and Zinc Concentrations and Fetal Development in California Holstein Dairy Cows
TLDR
Consistently lower liver Cu, Fe, Mn, and Zn concentrations in aborted fetuses suggest a nonspecific change in trace element status, which implies an effect of abortion, not a cause of abortion. Expand
Use of a clinical sepsis score for predicting bacteremia in neonatal dairy calves on a calf rearing farm.
TLDR
Results indicated that the model could be a useful tool for predicting bacteremia in ill calves in a clinical setting, and was validated through a 2nd sampling of 100 calves. Expand
Fecal shedding of Giardia duodenalis, Cryptosporidium parvum, Salmonella organisms, and Escherichia coli O157:H7 from llamas in California.
TLDR
Young llamas (crias) were more likely to be shedding cysts, compared with older llamas, and farm-level factors that increased the risk of shedding were large numbers of yearlings on the property, smaller pen sizes, largeNumbers of crias born during the previous year, and large pen or pasture populations. Expand
Relation among body condition score, serum urea nitrogen and cholesterol concentrations, and reproductive performance in high-producing Holstein dairy cows in early lactation.
TLDR
Body condition scoring (using a 5-point scale with quarter-point divisions) was performed on 66 Holstein dairy cows that began their second or later lactation in August, September, or October 1988 and Reproductive performance was evaluated in relation to body condition score and serum urea nitrogen and cholesterol concentrations.
