Liquid Chromatography With Tandem Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Symone T. Whalin
Liquid Chromatography With Tandem Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Symone T. Whalin
Masters Theses & Specialist Projects
Bovine mastitis, caused by a wide array of pathogens, results in a substantial economic loss for the dairy cattle livestock industry. β-defensins are a part of the bovine’s innate immune system and act as the first line of defense against mastitis. Only foundational research has been done on β-defensins’ ability to treat and prevent mastitis. There have been no analytical methods reported in the literature for analyzing β-defensins in bovine milk. This research aims to create an analytical approach to determine β-defensins in bovine milk. It is challenging to determine an analyte in a complex sample matrix, and milk is …
Comparison Of Bovine Mammary Involution And Intramammary Infections Following Intramammary Treatment With Casein Hydrolysate And Other Conventional Treatments At Dry-Off, Justine E. Britten, Kerry A. Rood, David J. Wilson
Comparison Of Bovine Mammary Involution And Intramammary Infections Following Intramammary Treatment With Casein Hydrolysate And Other Conventional Treatments At Dry-Off, Justine E. Britten, Kerry A. Rood, David J. Wilson
Animal, Dairy, and Veterinary Science Student Research
Alternatives to routine antibiotic treatment of dairy cattle during the dry period before their next calving are of interest. This was a preliminary study of whether intramammary infusion of casein hydrolysate, administered alone or combined with standard dry treatment, accelerated the rate of mammary involution early in the dry period. Four treatments were studied in a split udder design. One udder half was assigned a treatment, and the contralateral half was administered dry cow treatment + internal teat sealant as a control. Treatments were casein hydrolysate, casein hydrolysate + dry cow treatment, casein hydrolysate + teat sealant and casein hydrolysate …
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Honors Scholar Theses
Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …
Prevalence Of Bovine Viral Diarrhea Virus In Bovine Samples From The Intermountain West Of The U.S.A. - Comparison Between Age, Sex, Breed And Diagnostic Methods, David J. Wilson, T. J. Baldwin, E. J. Kelly, A. Van Wettere, G. Hullinger, J. Bunnell
Prevalence Of Bovine Viral Diarrhea Virus In Bovine Samples From The Intermountain West Of The U.S.A. - Comparison Between Age, Sex, Breed And Diagnostic Methods, David J. Wilson, T. J. Baldwin, E. J. Kelly, A. Van Wettere, G. Hullinger, J. Bunnell
Animal, Dairy, and Veterinary Science Faculty Publications
Prevalence of Bovine viral diarrhea virus (BVDV) (“detected” test results) among all bovine samples tested at the Utah Veterinary Diagnostic Laboratory from 2008 - 2013 was calculated, and results were compared by age, sex, or breed of the cattle and BVDV diagnostic test methods. Necropsies were tested for BVDV when lesions suggestive of infection were identified. Adults, juveniles and most calves were tested by antigen (Ag) capture ELISA, while fetuses and some calves were tested by real-time reverse transcriptase PCR. Cattle originated from Utah and surrounding states. Chi-square analyses were used to test for significant differences in BVDV prevalence between …

Feeding And Care Of Calves, R. R. Thalman
Feeding And Care Of Calves, R. R. Thalman
Nebraska Agricultural Experiment Station: Historical Circulars
It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.
White Scours Of Calves, L. Van Es
White Scours Of Calves, L. Van Es
Nebraska Agricultural Experiment Station: Historical Circulars
It becomes possible to understand some of the reasons for the occurrence of disorders among the newborn of animals kept under the usual conditions imposed by domestication. Among these, the subject of this circular, White Scours in Calves, occupies a prominent place.
