Phages Of Non-Diary Lactococci: Isolation And Characterization Of Phi L47, A Phage Infecting The Grass Isolate Lactococcus Lactis Ssp Cremoris Dpc6860, Daniel Cavanagh, Caitríona M. Guinane, Horst Neve, Aidan Coffey, R. Paul Ross, Gerald F. Fitzgerald, Olivia Mcauliffe
Phages Of Non-Diary Lactococci: Isolation And Characterization Of Phi L47, A Phage Infecting The Grass Isolate Lactococcus Lactis Ssp Cremoris Dpc6860, Daniel Cavanagh, Caitríona M. Guinane, Horst Neve, Aidan Coffey, R. Paul Ross, Gerald F. Fitzgerald, Olivia Mcauliffe
Department of Biological Sciences Publications
Lactococci isolated from non-dairy sources have been found to possess enhanced metabolic activity when compared to dairy strains. These capabilities may be harnessed through the use of these strains as starter or adjunct cultures to produce more diverse flavor profiles in cheese and other dairy products. To understand the interactions between these organisms and the phages that infect them, a number of phages were isolated against lactococcal strains of non-dairy origin. One such phage, ΦL47, was isolated from a sewage sample using the grass isolate L. lactis ssp. cremoris DPC6860 as a host. Visualization of phage virions by transmission electron …
Nebraska Bqa: Antibiotic Use Guidelines, Rob Eirich
Nebraska Bqa: Antibiotic Use Guidelines, Rob Eirich
Nebraska Beef Quality Assurance Program
Cattlemen have demonstrated a commitment to animal health through vaccination programs developed carefully in cooperation with their veterinarian. When animals must be treated with an antibiotic after disease diagnosis, producers need to follow important antibiotic use guidelines established through the National Beef Quality Assurance (BQA) program.

Audits And Assessments In Beef Cattle Production, Rob Eirich
Nebraska Beef Quality Assurance Program
Assessments and audits are becoming a part of doing business in beef cattle production, as we are seeing beef processors implementing third-party audits. Since beginning as the Nebraska Director of Beef Quality Assurance (BQA) in July, I have been studying and gathering information on the National Cattlemen's Beef Association (NCBA) Assessment Guides and third-party audits in the beef industry.

Humane use of preclinical large animal cancer models plays a critical role in understanding cancer biology and developing therapeutic treatments. Among the large animal candidates, goats have great potentials as sustainable sources for large animal cancer model development. Goats are easier to handle and cheaper to raise. The genome of the goats has been sequenced recently. It has been known that goats develop skin, adrenal cortex, breast and other types of cancers. Technically, goats are subject to somatic cell nuclear transfer more efficiently and exhibit better viability through the cloning process. Towards the development of a goat cancer model, we …
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …
Lactational Performance Of Dairy Cows Fed Yeast Derived Microbial Protein In Low And High Forage Diets, Angela Kristia Manthey
Lactational Performance Of Dairy Cows Fed Yeast Derived Microbial Protein In Low And High Forage Diets, Angela Kristia Manthey
Electronic Theses and Dissertations
The objective of this study was to investigate the effect of substituting soybean meal products with yeast-derived microbial protein [(YMP) DEMP; Alltech Inc., Nicholasville, KY] in diets containing two forage concentrations. Sixteen Holstein cows (4 primiparous and 12 multiparous) were randomly assigned to a replicated 4 × 4 Latin square in a 2 × 2 factorial arrangement of treatments. Diets contained low (LF; 45% of diet DM) or high forage (HF; 65% of diet DM) and YMP at 0 (NYMP) or 2.25% (WYMP) of the diet. The forage mix consisted of 67% corn silage and 33% alfalfa hay (DM basis). …
The Impact Of Dual Chamber Cow Waterbeds As A Freestall Base, Barbara Alice Wadsworth
The Impact Of Dual Chamber Cow Waterbeds As A Freestall Base, Barbara Alice Wadsworth
Theses and Dissertations--Animal and Food Sciences
The objectives of this research were to compare lying time, milk yield, rumination time, hock score, stall cleanliness, and stall temperature for 97 cows (Holsteins (n = 71), Jerseys (n = 10), and crossbreds (n = 16)) housed on Dual Chamber Cow Waterbeds™ (DCCW, Advanced Comfort Technology, Reedsburg, WI) or conventional rubber mattresses (MAT). This study was conducted at the University of Kentucky Coldstream Research Dairy Farm from January 18, 2012 to May 3, 2013. Lying times were longer (P < 0.01) for cows housed on the DCCW (10:32 ± 0:13) compared to cows housed on the MAT (9:47 ± 0:15). Milk yield was not different (P ≥ 0.05) between cows housed on the DCCW or MAT. Rumination times were greater (P = 0.03) for cows housed on MAT (6:44 ± 0:08) compared to cows housed on DCCW (6:29 ± 0:08). Hock scores were lesser (P = 0.02) for cows housed on DCCW (1.86 ± 0.03) compared to cows housed on MAT (1.97 ± 0.04). Stall cleanliness was not different (P ≥ 0.05) between the DCCW and the MAT. The DCCW stall temperature was warmer (P < 0.01) (13.29 ± 0.21 ⁰C) than the MAT (10.52 ± 0.21 ⁰C).
Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp
Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp
Theses and Dissertations--Animal and Food Sciences
Lameness and mastitis are the two most costly diseases in the dairy industry. Reduction of these diseases through housing and management is beneficial. Compost bedded pack (CBP) and sand freestall barns were compared in a long-term, on-farm study to assess the effect of housing on each disease. Another research objective was to evaluate the effects of ambient weather conditions on moisture and 20 cm internal temperature of CBP. Compost bedded pack moisture, C:N ratio, and internal temperature effects on cleanliness, mastitis, and bedding bacterial counts were also considered. The last research objective was to evaluate the economics of bedding material …

Animal, Dairy, and Veterinary Science Faculty Publications
Dairy herd-level prevalence of Mycobacterium avium subsp. paratuberculosis (MAP), causative agent of Johne’s disease (JD), Mycoplasma spp., and Bovine Viral Diarrhea (BVD) virus were estimated in Utah and surrounding states and compared to previous surveillance results. Milk was collected at 3-4 day intervals on 5 dates (duplicate samples) from each bulk tank on participating farms, samples analyzed separately. One frozen sample was shipped to a laboratory for JD/MAP testing with ELISA and real-time PCR, the other paired sample was shipped to another laboratory for mycoplasma and BVD testing. Mycoplasma was cultured on modified Hayflick medium, standard methods; BVD testing was …

Tsetse flies undergo drastic fluctuations in their water content throughout their adult life history due to events such as blood feeding, dehydration and lactation, an essential feature of the viviparous reproductive biology of tsetse. Aquaporins (AQPs) are transmembrane proteins that allow water and other solutes to permeate through cellular membranes. Here we identify tsetse aquaporin (AQP) genes, examine their expression patterns under different physiological conditions (blood feeding, lactation and stress response) and perform functional analysis of three specific genes utilizing RNA interference (RNAi) gene silencing. Ten putative aquaporins were identified in the Glossina morsitans morsitans (Gmm) genome, two more than …
