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 ...

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 ...

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 ...

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.

Towards The Identification Of Indicators For Metabolic Stress In Dairy Cattle , Megan Westall, Tara Mcdaneld, Diane Moody Spurlock Jan 2006

Towards The Identification Of Indicators For Metabolic Stress In Dairy Cattle , Megan Westall, Tara Mcdaneld, Diane Moody Spurlock

Animal Industry Report

Cows representing the average (AFP) and high (HFP) fat plus protein selection lines maintained at the ISU dairy were selected to participate in a study to identify indicators of energy mobilization. Differences between HFP and AFP cows in the expression of genes in adipose tissue, and the production of metabolic hormones are being defined. These differences will reveal physiological mechanisms important to the mobilization and utilization of energy reserves. This work will lead to the identification of indicators of metabolic stress, and aid in the selection of dairy cattle better able to sustain optimal levels of milk production.

Evaluation Of A Novel Winter Teat Dip Compared To Commercially Available Winter Dips To Enhance Teat Integrity During Winter, Jessica Schnitzler, Dawn Stendel, Leo L. Timms

Animal Industry Report

Winter conditions can lead to rapid dehydration and cracking of teat tissue, thus increasing mastitis risks. The objectives of these three winter trials were to compare application of a new novel commercial winter teat dip (1% iodine, 50% glycerine) to three existing commercially available winter teat dips and best management winter milking practices. Overall results for the 3 trials showed similar teat skin and end conditions (except teat skin in trial 5) for the 1% iodine, 50% glycerine dip as compared to 3 commercial winter teat dips. There were significant improvements in teat skin and end conditions over time for ...


Increasing Dairy Base With Millionaire Model Dairy Farms , Larry Tranel Jan 2006

Increasing Dairy Base With Millionaire Model Dairy Farms , Larry Tranel

Animal Industry Report

Those in the dairy industry need to recognize and promote dairy’s importance to the rest of the economy as each cow generates approximately $13,000 in economic activity in the form of jobs, goods and services created by a cow, along with paying taxes on the profits generated. Few recognize the ability of young producers especially to profit strongly with dairy as a career. For example, families in NE Iowa in 2000 and 2002 garnered approximately $100,000 net return to labor after an equity charge milking 100-140 cows with low/mediocre milk prices. In 2004, with much higher ...

Effect Of Prepartum Intramammary Treatment With Pirlimycin Hydrochloride On Prevalence Of Early First-Lactation Mastitis, Jessica Schnitzler, Leo L. Timms Jan 2006

Effect Of Prepartum Intramammary Treatment With Pirlimycin Hydrochloride On Prevalence Of Early First-Lactation Mastitis, Jessica Schnitzler, Leo L. Timms

Animal Industry Report

Holstein-Friesian heifers (n = 178) from a central Iowa dairy farm were enrolled in a study to determine whether prepartum intramammary treatment of dairy heifers with pirlimycin hydrochloride would reduce the prevalence of intramammary infection (IMI) and lower the somatic cell count (SCC) during early lactation or improve 305-day mature equivalent milk production. Heifers were assigned to treatment and control groups, and treated heifers received a single 50-mg dose of pirlimycin in each mammary quarter approximately 10 days prior to parturition.

Treated heifers had a higher overall cure rate and cure rate for IMI caused by coagulase negative staphylococci (CNS), but ...


Use Of The California Mastitis Test And An On-Farm Culture System For Strategic Identification And Treatment Of Fresh Cow Subclinical Intramammary Infections And Treatment Of Clinical Mastitis, April Boll, Leo L. Timms Jan 2006

Use Of The California Mastitis Test And An On-Farm Culture System For Strategic Identification And Treatment Of Fresh Cow Subclinical Intramammary Infections And Treatment Of Clinical Mastitis, April Boll, Leo L. Timms

Animal Industry Report

The purpose of this research was to evaluate the use of an on-farm culture system in conjunction with the California Mastitis Test for the strategic treatment of subclinical mastitis in fresh cows and clinical mastitis. CMT showed high NPV indicating it was very effective in determining uninfected quarters. However, PPV were low resulting in many CMT+ quarters being uninfected; thus many uninfected quarters being treated also. Cure rates in both the fresh and clinical animals did not change when treatment was delayed for twenty-four hours while waiting for culture results This would indicate that waiting for culture results before instituting ...
