A Literature Review On Injection-Site Lesions In Dairy Cows And Culling Decisions, Eric B. Parsons

Dairy Science

Currently dairy producers face particular problems concerning their culled cows and bulls, these problems must be addressed so dairy producers have the opportunity to improve the quality of beef produced from their cull dairy cows. At the moment, not much is known about culling decisions outside “break-even” numbers and poor cow conditioning. This literature review outlines the strategy behind culling decisions and looks into potential plans to develop progressive body conditioning and quality of meat sent to auction. Currently the dairy industry is not placing much demand into providing the livestock auctions and harvest plants with higher quality meat. This …

Characterization Of Changes In Composition And Physicochemical Properties Of Casein Micelles From Raw Milk To Buttermilk, Melissa Ann Looney

Master's Theses

It is well-documented that buttermilk has poor coagulation properties due to changes that occur to the casein micelles during the butter-making process. These modifications are generally attributed to the pasteurization of the cream upon which interactions between the proteins are promoted. It was hypothesized that churning is also a critical step for the changes that occur in composition of the casein micelles. The objective of this work was to learn more about the interactions that occur between casein micelles and MFGM components during the butter making process.

Raw cream was processed using a rotary churn at 18°C for approximately 30 …

The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez

Animal Science

Understanding the efficiency and digestibility of dietary nutrients in dairy heifers is essential for minimizing costs and environmental impacts of the dairy industry. The objective of this study was to interpret the effects of manipulating rumen-degradable protein (RDP) in a precision feeding system. Eight Holstein ruminally cannulated heifers (14.6 ± 0.1 mo of age, and 386 ± 9.1 kg of weight) were randomly assigned to 2 forage levels: HC (25% forage) and LC (75% forage) and to a degradable protein sequence [0% degradable protein from urea U, 100% casein C (no urea treatment U0); 33% U, 67% C …

Traversing Swanton Road, 14th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Service First: Embracing The Scholarship On Teaching And Learning Through Active Engagement In Parks, Recreation, And Tourism Education, Keri Schwab, Brian Greenwood, Daniel Dustin

Recreation, Parks and Tourism Administration

In this article, we turn the tripartite responsibility of teaching, scholarship, and service inside out. Rather than considering service to be a poor stepchild to scholarship and teaching, we reason that service as engaged scholarship should be the centerpiece of academic life, especially in an applied discipline like parks, recreation, and tourism. We reason further that improving engaged service should be the driving force behind good teaching, student learning, and scholarship. Finally, we reason that “impact factor,” a term commonly limited to citations in scholarly journals, should be expanded to include positive differences made on the ground in professional practice …

Little Evidence For Local Adaptation To Soils Or Microclimate In The Post-Fire Recruitment Of Three Californian Shrubs, Annette Bieger, Nishanta Rajakaruna, Susan Harrison

Biological Sciences

Background: Seedling recruitment following fire is an infrequent yet critical demographic transition for woody plants in Mediterranean ecosystems.

Aims: Here we examine whether post-fire seedling recruitment of three widespread Californian chaparral shrubs is affected by local adaptation within an edaphically and topographically complex landscape.

Methods: We reciprocally transplanted 6-month-old seedlings of Adenostema fasciculatum, Ceanothus cuneatus and Eriodictyon californicum to serpentine and sandstone soils, and cool northerly and warm southerly slopes.

Results: At the age of 2 years, none of the species manifested higher survival or growth on ‘home’ compared with ‘away’ soils or slopes, indicating an absence of local …

The Role Of Elevation And Soil Chemistry In The Distribution And Ion Accumulation Of Floral Morphs Of Streptanthus Polygaloides Gray (Brassicaceae), A Californian Nickel Hyperaccumulator, Nathaniel S. Pope, Michael Fong, Robert S. Boyd, Nishanta Rajakaruna

Biological Sciences

Background: The flora of serpentine/ultramafic soils provides an excellent model system for the study of natural selection in plant populations. Streptanthus polygaloides is a nickel hyperaccumulator that is endemic to serpentine soils in the Sierra Nevada of California, and has four floral morphs (yellow, purple, yellow-to-purple and undulate).

Aims: We investigate three hypotheses: (1) the purple morph occurs in colder, wetter climates than the yellow morph; (2) tissue–soil ionic relationships differ among morphs; and (3) morphs occur on soils with differing elemental concentrations.

Methods: We queried herbarium records to investigate patterns of occurrence among the yellow and purple floral morphs, …

Relationships Between The Built Environment And Walking And Weight Status Among Older Women In Three U.S. States, Philip J. Troped, Heather A. Starnes, Robin C. Puett, Kosuke Tamura, Ellen K. Cromley, Peter James, Eran Ben-Joseph, Steven J. Melly, Francine Laden

Kinesiology and Public Health

There are few studies of built environment associations with physical activity and weight status among older women in large geographic areas that use individual residential buffers to define environmental exposures. Among 23,434 women (70.0±6.9 years; range = 57-85) in 3 states, relationships between objective built environment variables and meeting physical activity recommendations via walking and weight status were examined. Differences in associations by population density and state were explored in stratified models. Population density (odds ratio (OR)=1.04 [1.02,1.07]), intersection density (ORs=1.18-1.28), and facility density (ORs=1.01-1.53) were positively associated with walking. Density of physical activity facilities was inversely associated with overweight/obesity …

Pacific Coast Producers: Picked And Canned At The Peak Of Ripeness, Alondra Bains, Brandon Hunt, Amanda Nichols, Xavier Rodriquez

Case Studies in Agribusiness

Pacific Coast Producers is a cooperative which processes, packs and ships tomatoes, peaches, pears and grapes. It started in 1971, when the bankruptcy of U.S. Products forced ten ranchers to look for a new outlet for their produce. They have since grown into a major co-packer, supplying over 5,000 labels for retailers across the U.S. As a California based packer, they face a number of issues, including environmental concerns, labor shortages and water supply reliability. However, their long-term outlook is positive
