Assessing The Needs Of Utah Dairy Farmers To Inform Extension Programming, Bruce F. Richards, Lendel Narine, Justin Clawson, Kalen Taylor, Jacob Hadfield, Jody Gale
Assessing The Needs Of Utah Dairy Farmers To Inform Extension Programming, Bruce F. Richards, Lendel Narine, Justin Clawson, Kalen Taylor, Jacob Hadfield, Jody Gale
Outcomes and Impact Quarterly
A needs assessment was conducted by the Utah State University Dairy Extension Team to identify the most urgent issues faced by Utah dairy farmers. The assessment found that the top five priority needs were implementing new technology, improving public perception of water use, managing risk, succession planning, and reducing feed costs. The results will guide dairy Extension programming in Utah. Several workshops and events have already been planned to address these needs. Overall, the assessment will help USU Extension provide research-based educational programs to meet the needs of the dairy industry in Utah.
Impact Of Ph And Palmitic Acid On Ruminal Fermentation And Microbial Community Composition, Lexie Padilla
Impact Of Ph And Palmitic Acid On Ruminal Fermentation And Microbial Community Composition, Lexie Padilla
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this study was to evaluate the effects of dietary palmitic acid and pH on rumen fermentation, fiber digestibility, and bacterial community composition. The two factors in the experiment were palmitic acid treatment and pH treatment. Palmitic acid treatments included a control diet compared to a diet containing 1.5% palmitic acid. pH treatments included normal pH (6.6 to 7.0) compared to low pH (6.0 to 6.4). Rumen fluid from a cow was added to artificial rumens to study the effects of the two treatments relative to fermentation and changes within the microbial community. Results of the study showed …
The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, Jacob A. Hadfield
The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, Jacob A. Hadfield
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Raising dairy heifers in a certified organic setting can be difficult for producers. Conventionally, heifers are raised in a confined setting, and fed a total mixed ration (TMR) that is balanced daily to contain all the needed nutrients for developing heifers. Organic producers can use a TMR in their operations, but due to high organic feed costs, many choose to raise their heifers in pasture-based systems. While pasture-based systems may lower costs, heifers on pasture commonly have lower rates of gain, which can be financially burdensome to producers. Grass-legume pastures may help improve rates of gain in heifers on pasture-based …

Evaluation Of Casein Hydrolysate As An Alternative Dry-Off Treatment And Milk Quality Management Tool In Dairy Cows, Justine Elena Britten
Evaluation Of Casein Hydrolysate As An Alternative Dry-Off Treatment And Milk Quality Management Tool In Dairy Cows, Justine Elena Britten

Mastitis, an infection of the mammary gland, is the most common and expensive animal health problem for the dairy industry and affects every dairy farm to some degree. This disease complex is painful for dairy cows, increases the on-farm use of antibiotics, presents a threat to milk quality and is a waste of time, money and milk production. Each year, the dairy industry loses as much as a billion dollars to mastitis.
Many cows will experience mastitis at least once during a lactation cycle and some animals will develop recurring mastitis episodes in a single mammary quarter. These mastitic quarters …

Background: Calcium intake during early adolescence falls short of requirements for maximum bone accretion. Parents and the home food environment potentially influence children’s calcium intakes. This study aimed to quantify parental psychosocial factors (PSF) predicting calcium intakes of Asian, Hispanic, and non-Hispanic white (NHW) early adolescent children from a parental perspective.
Methods: This was a cross-sectional study involving the administration of a validated calcium-specific food frequency questionnaire to a convenience sample of children aged 10–13 years and the primary individual responsible for food acquisition in the child’s household. Based on Social Cognitive Theory, parental factors potentially associated with children’s calcium …
Optimizing Robotic Milk: A Qualitative Research Approach To Understanding Challenges That May Inhibit Optimal Usage Of Automatic Milking Systems In Northern Utah, Jessica Felts
Fall Student Research Symposium 2018
Automatic Milking Systems (AMS) – or robotic milkers – have been on the market for over twenty years. However, AMS introduction is relatively new to the Western U.S., and requires challenging adjustments and new management systems.
Is Mycoplasma Bovis In Sand Bedding Infectious To Dairy Calves?, David J. Wilson, Thomas J. Baldwin
Is Mycoplasma Bovis In Sand Bedding Infectious To Dairy Calves?, David J. Wilson, Thomas J. Baldwin
All Current Publications
Mycoplasmas are unusual bacteria that can infect all ages of cattle, and can cause arthritis, pneumonia, and death. Infected dairy cows may also contract mastitis, metritis, or virtually cease milk production. The most common mycoplasma affecting cattle is M. bovis; there are several other Mycoplasma spp. as well. Because standard microbial culture methods do not isolate Mycoplasma spp., special laboratory methods are needed for diagnosis. Mycoplasma spreads by inhalation and respiratory secretions and also at milking time via contaminated inflations in milking units. Mycoplasma spp. have also been detected in straw, sand, recycled manure, and other bedding, often associated …

Undefined mesophilic mixed (DL-type) starter cultures are composed of predominantly Lactococcus lactis subspecies and 1–10% Leuconostoc spp. The composition of the Leuconostoc population in the starter culture ultimately affects the characteristics and the quality of the final product. The scientific basis for the taxonomy of dairy relevant leuconostocs can be traced back 50 years, and no documentation on the genomic diversity of leuconostocs in starter cultures exists. We present data on the Leuconostoc population in five DL-type starter cultures commonly used by the dairy industry. The analyses were performed using traditional cultivation methods, and further augmented by next-generation DNA sequencing …

Using A Rising Plate Meter To Determine Paddock Size For Rotational Grazing, Jennifer W. Macadam, Sara R. Hunt
Using A Rising Plate Meter To Determine Paddock Size For Rotational Grazing, Jennifer W. Macadam, Sara R. Hunt
All Current Publications
For rotational grazing of pastures to be most successful, it’s important to match pasture production to ruminant intake, because both can change during the grazing season. This publication shows how a rising plate meter can be used to calculate available pasture dry matter, allowing pasture managers to optimize pasture utilization and ruminant production on pasture.
Improvement Of Nutrient Utilization Efficiency, Ruminal Fermentation And Lactational Performance Of Dairy Cows By Feeding Birdsfoot Trefoil, Rachael G. Christensen
Improvement Of Nutrient Utilization Efficiency, Ruminal Fermentation And Lactational Performance Of Dairy Cows By Feeding Birdsfoot Trefoil, Rachael G. Christensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Condensed tannins (CT) are compounds that have shown potential to reduce the environmental impact of dairy farming waste products. In two live animal studies and a continuous culture study, it was hypothesized that feeding birdsfoot trefoil (Lotus corniculatus, BFT), a CT-containing legume, would improve nutrient utilization, milk, and component yield of dairy cows compared with feeding alfalfa hay or grass pasture in two studies, while feeding BFT forage would decrease methane production and improve rumen fermentation in addition to concentrate supplementation was the hypothesis of the third study. Reduction in milk urea nitrogen (MUN) and …

Inhibition Of L. Monocytogenes Growth In Dairy Products With Lactose Monolaurate, Yao Chen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Foodborne illness is a very severe problem, and it is now a serious issue throughout the world. Within the 5 pathogens that cause more than 90 percent of foodborne illnesses, Listeria monocytogenes ranks the third. L. monocytogenes causes the highest death rate among all foodborne pathogens, and it represents high risks to pregnant women, fetuses and people with weak immune systems. Therefore, inhibition of Listeria in food becomes a relevant topic in food industry and scientific field nowadays.
Adding antibacterial agents into food products is considered as an effective method to inhibit Listeria growth. My research was focused on characterization …
