Letter to the Editor: New Terminology in the Journal of Dairy Science
Dec 01, 2008; ... In some recently published papers in the Journal of Dairy Science, new terminology was introduced. The terms were new at least to me as a nonnative speaker of English. I would like to know the definition for the term "generic mastitis" (Bar et al., 2008) and how it differs from the simple term ...
Effect of Mixing During Fermentation in Yogurt Manufacturing
Dec 01, 2008; ... ABSTRACT In traditional yogurt manufacturing, the yogurt is not agitated during fermentation. However, stirring could be beneficial, particularly for improving heat and mass transport across the fermentation tank. In this contribution, we studied the effect of low-speed agitation during ...
Characterization of Human Mucin (MUC15) and Identification of Ovine and Caprine Orthologs
Dec 01, 2008; ... ABSTRACT The glycoprotein MUC15 (mucin 15) was initially isolated from the bovine milk fat globule membrane. The present work demonstrates the existence of immunologically similar proteins (~130 kDa) in ovine, caprine, porcine, and buffalo milk samples. Purification and N-terminal amino ...
French Marine Bark Extract Pycnogenol as a Possible Enrichment Ingredient for Yogurt
Dec 01, 2008; ... ABSTRACT The influence of Pycnogenol, French marine bark extract, added to yogurt preparation on the viability of Lactobacillus delbrueckii ssp. bulgaricus and Streptococcus thermophilus and on pH, titratable acidity, macronutrients, and folate content were evaluated throughout the shelf ...
Effect of Tetrasodium Pyrophosphate on the Physicochemical Properties of Yogurt Gels
Dec 01, 2008; ... ABSTRACT The effect of tetrasodium pyrophosphate (TSPP) on the properties of yogurt gels was investigated. Various concentrations (0.05 to 0.2%) of TSPP were added to preheated (85°C for 30 min) reconstituted skim milk, which was readjusted to pH 6.50. Milk was inoculated with 2% starter ...
Characterization of the Rheological, Textural, and Sensory Properties of Samples of Commercial US Cream Cheese with Different Fat Contents
Dec 01, 2008; ... ABSTRACT In this study, 18 commercial samples of cream cheeses from the United States, including full-fat, Neufchatel or one-third less fat, and fat-free cheeses were analyzed for their rheological, textural, and sensory properties. Dynamic rheological properties were measured by ...
Prebiotic Properties of Epilactose
Dec 01, 2008; ... ABSTRACT We recently reported that cellobiose 2-epimerase from Ruminococcus albus effectively converted lactose to epilactose. In this study, we examined the biological effects of epilactose on intestinal microbiota, bile acid metabolism, and postadministrative plasma glucose by animal ...
Comparative Study on Heat Stability and Functionality of Camel and Bovine Milk Whey Proteins
Dec 01, 2008; ... ABSTRACT Heat stability, emulsifying, and foaming properties of camel whey have been investigated and compared with that of bovine whey. Camel whey is similar to bovine whey in composition, but is deficient in β-lactoglubulin (β-LG), a major component of bovine whey. Whether ...
Short Communication: Culture-Independent Detection of Lactic Acid Bacteria Bacteriocin Genes in Two Traditional Slovenian Raw Milk Cheeses and Their Microbial Consortia
Dec 01, 2008; ... ABSTRACT Two Slovenian traditional raw milk cheeses, Tolminc (from cows' milk) and Kraski (from ewes' milk), were examined for the presence of 19 lactic acid bacteria bacteriocin genes by PCR analysis of total DNA extracts from 9 cheeses and from consortia of strains isolated from these ...
Molecular Epidemiology and Population Structure of Bovine Streptococcus uberis
Dec 01, 2008; ... ABSTRACT The molecular epidemiology and population structure of 30 bovine subclinical mastitis field isolates of Streptococcus uberis, collected from 6 Portuguese herds (among 12 farms screened) during 2002 and 2003, were examined by using pulsed-field gel electrophoresis (PFGE) for ...
Lameness, Activity Time-Budgets, and Estrus Expression in Dairy Cattle
Dec 01, 2008; ... ABSTRACT The aim of the present study was to identify specific behavioral patterns that contribute to diminished estrus expression in lame cows. Behavioral scan and focal sampling were used to examine the effect of lameness on daily activity budgets, sexual behavior, feeding activities, ...
Automatic Detection of Clinical Mastitis Is Improved by In-Line Monitoring of Somatic Cell Count
Dec 01, 2008; ... ABSTRACT This study explored the potential value of in-line composite somatic cell count (ISCC) sensing as a sole criterion or in combination with quarter-based electrical conductivity (EC) of milk, for automatic detection of clinical mastitis (CM) during automatic milking. Data ...
Increasing Heat Stress Relief Produced by Coupled Coat Wetting and Forced Ventilation
Dec 01, 2008; ... ABSTRACT Coupling repeated wetting of the coat and forced ventilation is most efficient in removing heat stress in more humid climates. The procedure was initiated approximately 24 yr ago and is widely used, but the impact of air velocity on the efficiency of heat stress relief has not ...
Precipitation and Temperature Effects on Mortality and Lactation Parameters of Dairy Cattle in California
Dec 01, 2008; ... ABSTRACT Data from 3 commercial rendering companies located in different regions of California were analyzed from September 2003 through August 2005 to examine the relationship of dairy calf and cow mortality to monthly average daily temperature and total monthly precipitation ...
Detection of Clinical Mastitis with the Help of a Thermal Camera
Dec 01, 2008; ... ABSTRACT Increasing dairy farm size and increase in automation in livestock production require that new methods are used to monitor animal health. In this study, a thermal camera was tested for its capacity to detect clinical mastitis. Mastitis was experimentally induced in 6 cows with ...
Economy, Efficacy, and Feasibility of a Risk-Based Control Program Against Paratuberculosis
Dec 01, 2008; ... ABSTRACT Long-term effects of paratuberculosis on within-herd prevalence and on-farm economy of implementing riskbased control strategies were compared with alternative strategies by using a herd-simulation model. Closing transmission routes is essential for effective control of ...
Colostrum and Milk as Risk Factors for Infection with Mycobacterium avium subspecies paratuberculosis in Dairy Cattle
Dec 01, 2008; ... ABSTRACT Mycobacterium avium ssp. paratuberculosis (MAP) infections cause major losses to the dairy industry. Transmission of MAP occurs primarily via feces and in utero, but MAP can also be excreted in colostrum and milk. The objective of this study was to determine whether colostrum ...
