Effects Of Filtration Temperature And Heat Treatment On Composition And Rheological Properties Of Whole Milk Ultrafiltration Retentates, John W. Montella

Master's Theses

ABSTRACT

Effects of Filtration Temperature and Heat Treatment on Composition and Rheological Properties of Whole Milk Ultrafiltration Retentates

John William Montella

For the first part of my thesis, the effects of filtration temperature and heat treatment on the compositional properties of whole milk Ultrafiltration retentate (UF) were studied. Ultrafiltration is primarily run at temperatures in the range of 50-55°C but more and more plants are starting to filter at refrigeration temperatures. In the ultrafiltration of milk, filtration temperature can affect the composition of the retentate by affecting the chemistry of milk components. The application of a pasteurization step can also …

Got Controversy - Milk Does, Margaret Sova Mccabe

Law Faculty Scholarship

This article analyzes ongoing controversy over how to best label rBST-free milk. Recombinant bovine somatotropin is a genetically engineered drug administered by some farmers to their dairy herds to increase milk production. FDA first approved its use in 1994, despite great controversy. The FDA also issued labeling guidelines that allowed voluntary disclosure of rBST-free milk, so long as it carried the disclaimer that no difference could be detected between milk produced with rBST and rBST-free. The controversy continues today as consumers express a preference for rBST-free milk and many rBST-free producers label their milk this way. "Conventional" milk (with rBST) …

Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell

Bulletins 4000 -

Conventional agriculture acidifies soil. As your soil becomes more acid, productive pasture species disappear and are replaced by species of low agricultural value. It is a waste of money to apply expensive fertiliser to pastures which are inherently poorly productive because they are growing in an acid soil.

The paper examines the types of lime available, how to select lime for quality and when and how much lime to apply. Maganese toxity and aluminum toxicity are examine, how to test your soil, and affect of soil acidity on bacteria and other microorgansims.

B851: A Comparative Analysis Of Organic Dairy Farms In Maine And Vermont: Farm Financial Information From 2004 To 2006, Timothy J. Dalton, Robert Parsons, Richard Kersbergen, Glenn Rogers

Bulletins

The purpose of this bulletin is to provide an insight into the relative financial performance of organic dairy farming through the examination of three years of detailed farm financial records. Farm financial records were collected in person by trained enumerators from organic dairy operations in Maine and Vermont for the 2004–2006 production years. These farm records are complemented by surveys on farm and farmer characteristics along with farmers’ motivational interests for organic dairy production and performance satisfaction. This report, therefore, provides a rich financial perspective on the evolution of organic dairy farming performance unlike single-season surveys.

Odor Evaluation And Gas Emission From Manure Of Dairy Heifers Fed High/Low - Forage Quality And High/Low-Concentrate Diets, Patrick A. Topper, Robin Brandt, Arlene Adviento-Borbe, Gustavo J. Lascano, Arlyn J. Heinrichs, Eileen F. Wheeler

Dairy Science

A heifer feeding trial evaluated the impact of high/low forage quality and high/low concentrate level nutrient-balanced diets on simultaneous odor and gas emissions from the manure. Gas concentration was determined using an infrared photoacoustic analyzer over a 24-hour period using a steady-state flux chamber setup containing urine:feces as-excreted from eight individual heifers. Odorous air samples were collected from chamber headspace and evaluated by six human assessors for pleasantness, intensity and detection threshold using a forced-choice dynamic olfactometer. Ammonia emission ranged from 0.64 to 3.94 mg NH3 cm-2 d-1 across diets. Average ammonia emission from the low concentrate (80% forage) diets …

Mycotoxins In Corn Distillers Grains: A Concern In Ruminants?, Alvaro Garcia, Kenneth Kalscheur, Arnold Hippen, David Schingoethe, Kurt A. Rosentrater

Kurt A. Rosentrater

Themain fungi that produce toxins during storage belong to three genera: Aspergillus, Fusarium, and Penicillium. When dealing with cattle diets, it is not easy to correlate the presence of mycotoxins to that of molds. The same types of molds can produce different types of toxins, and different types ofmolds can produce the samemycotoxin.

The primary targets for SARS-CoV infection are the epithelial cells in the respiratory and intestinal tract. The angiotensin-converting enzyme 2 (ACE-2) has been identified as a functional receptor for SARS-CoV. ACE-2 has been shown to be expressed at the apical domain of polarized Calu-3 cells. In this report, interferon alfacon 1 was examined for inhibitory activities against SARS-CoV on human lung carcinoma epithelial Calu-3 cell line and the other three African green monkey kidney epithelial cell lines. Interferon alfacon 1 demonstrated significant antiviral activity in neutral red uptake assay and virus yield reduction assay. The data might provide an important …

Is The Anti-Psychotic, 10-(3-(Dimethylamino)Propyl)Phenothiazine (Promazine), A Dangerous Drug With Which To Treatsars Infections? Efficacy Of Promazine On Sars-Cov Replication In A Mouse Model, Dale L. Barnard, C. W. Day, K. Bailey, M. Heiner, R. Montgomery, L. Lauridsen, K. H. Jung, P. K. Chan, J. K. Li, R. W. Sidwell

Animal, Dairy, and Veterinary Science Faculty Publications

Phenothiazine and derivatives were tested for inhibition of SARS-CoV replication. Phenothiazine slightly inhibited SARS-CoV replication in a neutral red (NR) uptake assay. Adding a propylamino group to give promazine reduced virus yields (VYR assay) with an EC90 = 8.3 ± 2.8 μM, but without selectivity. Various substitutions in the basic phenothiazine structure did not promote efficacy. Phenazine ethosulfate was the most potent compound by VYR assay (EC90 = 6.1 ± 4.3 μM). All compounds were toxic (IC50 = 6.6–74.5 μM) except for phenoxathiin (IC50 = 858 ± 208 μM) and 10-(alpha-diethylamino-propionyl) phenothiazine·HCl (IC50 = 195 ± 71.2 μM). Consequently, none …

Kansas Agricultural Experiment Station Research Reports

In this experiment, we evaluated the effects of varying alfalfa inclusion rate in diets containing 31% wet corn gluten feed on a dry matter basis. Eighty lactating Holstein cows were allocated into groups of 10 and assigned to 1 of 8 pens balanced for parity, stage of lactation, and milk yield. Diets were formulated to contain 0, 7, 14, or 21% alfalfa on a dry matter basis. Diets containing greater proportions of alfalfa had less corn silage and soybean meal but more corn grain. Feed intake, milk production, body weight, and body condition score were monitored, and effects of increasing …

Resynchronized Pregnancyrates In Dairy Cattle: Timingof Gonadotropin-Releasinghormone Injection Before Timedartificial Insemination (2008), C.A. Martel, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Lactating dairy cows and replacement virgin heifers of unknown pregnancy status were treated with either gonadotropin-releasing hormone (GnRH) or saline to initiate a resynchronization program that was continued 7 days later when a not-pregnant diagnosis was determined. Nonpregnant cattle were administered prostaglandin F2αand then either injected with GnRH 56 hours later and artificially inseminated (AI) by appointment at 72 hours or injected and inseminated concurrently at 72 hours. Injection of GnRH at 56 hours produced more pregnancies than injection of GnRH at 72 hours when AI was administered at 72 hours in both treatments (30.9 vs. 15.2%). Further, starting the …

Opportunities With Low Profilecross Ventilated Freestallfacilities (2008), John F. Smith, Joseph P. Harner, Barry J. Bradford, M.W. Overton

Kansas Agricultural Experiment Station Research Reports

Low profile cross ventilated freestall buildings are one option for dairy cattle housing. These facilities allow producers to control the cows' environment during all seasons of the year. As a result, an environment similar to the thermoneutral zone of a dairy cow is maintained during both summer and winter, resulting in more stable core body temperatures. Low profile cross ventilated facilities allow buildings to be placed closer to the parlor, thus reducing the time cows are away from feed and water. Other advantages include a smaller overall site footprint than naturally ventilated facilities and less critical orientation because naturally ventilated …
