The Cost Of Affordable Food, Candice L. Cobuzzi

SURGE

When someone puts a piece of food in front of me, I don’t just see a piece of food.

Instead, I see an innocent cow being cornered by a forklift and slaughtered, its limp, moist tissue hung on a long conveyer belt with hundreds of others.

I see hundreds of chemically-injected chickens packed into a dark barn with no hope of seeing sunlight in their lifetime.

I see immigrants pulled from their houses like criminals, taken away from the lives they’ve spent years building for themselves and their families, working for the same food company that courted them into the …

Effect Of Adding Salt During The Diafiltration Step Of Milk Protein Concentrate Powder Manufacture On Mineral And Soluble Protein Composition, Vandna Sikand, Phillip S. Tong, John Walker

Dairy Science

Milk protein concentrate (MPC) powders offer a great potential for use in an array of food applications because of their nutritional and functional values. However, MPC powders with protein content ≥80% (MPC80) exhibit poor solubility and hence restrict their potential use. The objective of this study was to determine the impact of adding salt during the diafiltration stage of MPC80 manufacture on solubility, turbidity, and to compare minerals and protein content of supernatants of ultracentrifuged samples with control sample. Three types of samples were produced: MPC80-C (control) with or without salt treatment, MPC80-Na (150 mM NaCl), and MPC80-K (150 mM …

Milk Fat Globule Membrane Isolated From Buttermilk Or Whey Cream And Their Lipid Components Inhibit Infectivity Of Rotavirus In Vitro, K. L. Fuller, T. B. Kuhlenschmidt, M. S. Kuhlenschmidt, Rafael Jiménez-Flores, S M. Donovan

Dairy Science

Milk fat is encapsulated in a milk fat globule membrane (MFGM) that contains bioactive glycoproteins and glycolipids. The MFGM inhibits infectivity of rotavirus (RV), activity that has been attributed to its glycoprotein and carbohydrate components. However, previous studies of proteins and oligosaccharides in the MGFM have not accounted for all the bioactivity associated with the complete MFGM. The lipid fraction of the MFGM accounts for half of its composition by weight, and we postulate that this fraction should be tested by itself to determine if it plays a role in antiviral activity. Herein, the anti-RV activity of an organic extract …

Testing The Effect Of Grapefruit Seed Extract (Gfse) On The Mastitsis-Causing Alga, Prototheca, Kendra Janelle Macdonald

Honors College

Mastitis is an inflammation of the mammary gland that costs the United States dairy industry between $1.7 and $2 billion annually [9]. Approximately 97% of mastitis infections are caused by bacteria, which can be treated with antibiotics [2]. However, mastitis infections can be caused by the alga, Prototheca. Specifically, it is P. zopfii (genotype 2) and P. blaschkeae that have been found in cows with mastitis [7]. There are currently no approved treatments for protothecal mastitis. The following experiments a tested the effects of grapefruit seed extract (GFSE) on P. zopfii (genotype 2) using spectrophotometry and plating techniques. GFSE was …

Rna Sequencing To Study Gene Expression And Single Nucleotide Polymorphism Variation Associated With Citrate Content In Cow Milk, A. Cánovas, G. Rincón, A. Islas-Trejo, R. Jiménez-Flores, A. Laubscher, J. F. Medrano

Dairy Science

The technological properties of milk have significant importance for the dairy industry. Citrate, a normal constituent of milk, forms one of the main buffer systems that regulate the equilibrium between Ca2+ and H+ ions. Higher-than-normal citrate content is associated with poor coagulation properties of milk. To identify the genes responsible for the variation of citrate content in milk in dairy cattle, the metabolic steps involved in citrate and fatty acid synthesis pathways in ruminant mammary tissue using RNA sequencing were studied. Genetic markers that could influence milk citrate content in Holstein cows were used in a marker-trait association study to …

Effects Of Addition Of Somatic Cells To Caprine Milk On Cheese Quality, D. Sánchez-Macías, A. Morales-Delanuez, A. Torres, L. E. Hernández-Castellano, R. Jiménez-Flores, N Castro, A. Argüello

Dairy Science

Milk quality criteria and limits for somatic cell count (SCC) established in many countries make it difficult to maintain SCC of bulk tank goat milk below the threshold, due to non-infection factors linked to goat physiology. The aim of this study was to objectively verify the effects of SCC on fresh caprine milk cheese. Somatic cells were recovered from pooled healthy goat milk, and added to low SCC raw or pasteurised goat milk. Miniature cheeses were made and evaluated after 1 and 7 d. Somatic cells had a major effect on lipolysis, increasing free fatty acids regardless of whether milk …

Associations Of Housing, Management, Milking Activity, And Standing And Lying Behavior Of Dairy Cows Milked In Automatic Systems, Justine A. Deming, Renée Bergeron, Kenneth E. Leslie, Trevor J. Devries

Farm Animal Husbandry Collection

The objective of this cross-sectional study was to describe the housing, feeding management, and characteristics (parity and stage of lactation) of cows on commercial automatic milking system (AMS) dairies and their associations with the standing and lying behavior patterns and milking activity (frequency and yield) of lactating dairy cows. Thirteen AMS herds were enrolled in the study, with an average herd size of 71 ± 30 (mean ± SD; range: 34 to 131) lactating cows. All of the herds used freestall barns, each set up for free cow traffic to the AMS. On-farm measurements were taken to determine stocking density …

Nebraska Bqa: Herd Health Plan/Protocol, Rob Eirich

Nebraska Beef Quality Assurance Program

Nebraska cattlemen have demonstrated a commitment to the integrity of today's beef products by implementing sound cattle management practices. Consumers are looking for beef raised in a healthy and safe environment. An appropriate Herd Health Plan/Protocol ensures that all cattle are raised in the best health.

Nebraska Bqa: Veterinarian Client Patient Relationship, Rob Eirich

Nebraska Beef Quality Assurance Program

Beef producers are committed producing a high quality, safe and wholesome beef product. A commitment to herd health and veterinary input is critical to achieving this goal. To this end, developing a veterinarian client-patient relationship (VCPR) is important and will benefit all aspects of cattle performance. Veterinarians' working understanding of cattle disease and parasites can help cattle raisers develop targeted vaccination and treatment programs.

Physiological Level Production Of Antigen-Specific Human Immunoglobulin In Cloned Transchromosomic Cattle, A. Sano, H. Matsushita, H. Wu, J. Jiao, P. Kasinathan, E. J. Sullivan, Z. Wang, Y. Kuroiwa

Animal, Dairy, and Veterinary Science Faculty Publications

Therapeutic human polyclonal antibodies (hpAbs) derived from pooled plasma from human donors are Food and Drug Administration approved biologics used in the treatment of a variety of human diseases. Powered by the natural diversity of immune response, hpAbs are effective in treating diseases caused by complex or quickly-evolving antigens such as viruses. We previously showed that transchromosomic (Tc) cattle carrying a human artificial chromosome (HAC) comprising the entire unrearranged human immunoglobulin heavy-chain (hIGH) and kappa-chain (hIGK) germline loci (named as κHAC) are capable of producing functional hpAbs when both of the bovine immunoglobulin mu heavy-chains, bIGHM and bIGHML1, are homozygously …
