A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores Dec 2006

A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores

Dairy Science

The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by …


Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong Dec 2006

Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong

Dairy Science

Our aim was to investigate how two conditions of whey processing, pH and heat treatment, affect the physical properties of stirred yoghurts fortified to 45 g protein kg−1 with whey protein concentrates (WPC). Cheddar whey was heated at pH 6.4 or pH 5.8 at 72 °C for 15 s, eventually heated further at 82 or 88 °C for 78 s, ultrafiltered, and spray dried. Resulting WPC contained 38% protein; the denaturation level of the whey protein was 10–53%. There were significant (P

Performance Of Pre And Post-Partum Weather Stressed Cows Supplemented With Yeast Culture, Fabian Ortiz May 2006

Performance Of Pre And Post-Partum Weather Stressed Cows Supplemented With Yeast Culture, Fabian Ortiz

Masters Theses & Specialist Projects

Livestock have been fed yeast as a feed supplement for more than 100 years Stone, C. 00). Yeast is a microscopic, single cell fungi of the plant kingdom. Of the 50,000 species of fungi, only 60 different genera of yeast representing about 500 different species exist. A few of these are used commercially in the animal feed industry as active dry yeast or yeast culture (Kreger, van Rij, 1984). Yeast culture consists of live yeast cells, plus the medium on which yeast is grown. Yeast products are commonly fed as pro-biotics, but little is known about their effects. Some studies …

High-Risk Human Papilloma Virus Infection Decreases The Frequency Of Dendritic Langerhans’ Cells In The Human Female Genital Tract, Rafael Jiménez-Flores, Rene Mendez-Cruz, Jorge Ojeda-Ortiz, Rebeca Muñoz-Molina, Oscar Balderas-Carrillo, Maria De La Luz Diaz-Soberanes, Serge Lebecque, Sem Saeland, Adrian Daneri-Navarro, Alejandro Garcia-Carranca, Stephen E. Ullrich, Leopoldo Flores-Romo

Dairy Science

Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a dense …

Impacts Of A Manure Composting Program On Stream Water Quality, A. Bekele, A. M.S. Mcfarland, A. J. Whisenant Jan 2006

Impacts Of A Manure Composting Program On Stream Water Quality, A. Bekele, A. M.S. Mcfarland, A. J. Whisenant

Faculty Publications

In February 2001, the Texas Commission on Environmental Quality (TCEQ) adopted a Total Maximum Daily Load (TMDL) for soluble reactive phosphorus (SRP) along the North Bosque River. Within this TMDL, dairy waste application fields were identified as the major nonpoint-source contribution of nutrients. In September 2000, a manure composting program was initiated that resulted in about 500,000 metric tons of dairy manure being hauled to composting facilities and exported from the watershed through December 2004. To evaluate the impact of the manure composting program on stream water quality, storm event mean concentrations of nutrients and total suspended solids were compared …


The Cattle Industry's Guidelines For The Care And Handling Of Cattle Jan 2006

The Cattle Industry's Guidelines For The Care And Handling Of Cattle

Nebraska Beef Quality Assurance Program

Cattlemen have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the wellbeing of cattle, individual animal health and herd productivity. Cattle are produced in very diverse environments and geographic locations in the United States. There is not one specific set of production practices that can be recommended for all cattle producers. Personal experience, training and professional judgment can serve as a valuable resource for providing proper animal care.

Animal, Dairy, and Veterinary Science Faculty Publications

Compounds approved for therapeutic use and in vitro inhibitors of severe acute respiratory syndrome coronavirus (SARS-CoV) were evaluated for inhibition in the mouse SARS-CoV replication model. A hybrid interferon, interferon alpha (IFN-alpha) B/D, and a mismatched double-stranded (ds) RNA interferon (IFN) inducer, Ampligen® (poly I:poly C124), were the only compounds that potently inhibited virus titres in the lungs of infected mice as assessed by CPE titration assays. When mice were dosed intraperitoneally (i.p.) with IFN-alpha B/D once daily for 3 days beginning 4 h after virus exposure, SARS-CoV replication in the lungs of infected mice was reduced by 1 log10 …

Comparative Toxicosis Of Sodium Selenite And Selenomethionine In Lambs, A. K. Tiwary, B. L. Stegelmeier, K. E. Panter, L. F. James, Jeffery O. Hall

Animal, Dairy, and Veterinary Science Faculty Publications

Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite or selenomethionine and were monitored for 7 days, after which they were euthanized and necropsied. Twelve randomly assigned treatment groups consisted of animals given 0, 1, 2, 3, or 4 mg of Se/kg of body weight as sodium selenite, or 0, 1, …

Detection Of Early Stages Of Myxobolus Cerebralis In Fin Clips From Rainbow Trout (Onchorynchus Mykiss), Ramona T. Skirpstunas, J. Hergert, Thomas J. Baldwin

Animal, Dairy, and Veterinary Science Faculty Publications

A nested polymerase chain reaction (PCR) assay was used to detect early stages of Myxobolus cerebralis in caudal and adipose fin samples from rainbow trout (RT). To determine sensitivity, groups of 10 RT were exposed to 2,000 M. cerebralis triactinomyxons/fish for 1 hour at 15 degrees C and subsequently moved to clean recirculating water. Fish were held for 2 and 6 hours and 1, 2, 3, 5, 7, 10, 30, and 60 days before sampling by nonlethal fin biopsy. Nested PCR performed on fin clips showed that M. cerebralis DNA was detected in caudal fin tissue in 100% of fish …

Humans infected with West Nile virus (WNV) may clinically present with symptoms that are suggestive of neurological infection. Nearly all treatments of WNV disease have been effective in animal models only if administered before or soon after viral challenge. Here, we evaluated whether a potent neutralizing anti-WNV humanized monoclonal antibody (MAb), hE16, could improve the course of disease in a hamster model when administered after the virus had infected neurons in the brain. Five days after viral injection, WNV was detected in the brains of hamsters by cytopathic assay, quantitative reverse-transcription polymerase chain reaction, and immunohistochemical staining of WNV envelope …
