In 2000–2002 samples of raw materials (milk and beef, 518 samples), ready-to-cook foods and final products from milk (30 and 200 samples) and from meat (105 and 110 samples) and swabs from surfaces in two meat-processing plants (41 samples) were examined for the presence of Listeria monocytogenes (L. monocytogenes). 70 isolates were tested using the standard microdilution method for the suscept...

The standard of comparison for dairy production records is the 305-day lactation, and much research has been directed to estimating 305-day milk and fat records from incomplete or in-progress records. This study was to determine the effect of several methods of extending incomplete records on sire evaluation. Complete 305-day milk and fat records of first lactations of 73,724 daughters of 1,362...

Introduction Milk somatic cell count is considered as an indicator for raw milk quality and udder health status in dairy cows (4, 6). Many approaches have been made to determine milk somatic cell counts in dairy cow and goat both in the field and laboratory including California Mastitis Test (CMT, a cow side test), Fossomatic cell count (FSCC), and Direct Microscopic Count (DMC) (1,7). These co...

Non-thermal processing methods, such as pulsed electric field (PEF) and tangential-flow microfiltration (TFMF), are emerging processing technologies that can minimize the deleterious effects of high temperature short time (HTST) pasteurization on quality attributes of skim milk. The present study investigates the impact of PEF and TFMF, alone or in combination, on color and volatile compounds i...

in this research, 272977 test day records collected from 659 herds during years 2001 to 2011 by the iranian animal breeding center were used. in the first section the ability of different models to predict daily milk yield from alternative milk recording was tested. the result showed that a complex model including noon milking time plus the effect of lactation curve of ali and schaeffer functio...

background: the extensive consumption of milk anddairy products makes these foodstuffs targets for potentialadulteration with financial gains for unscrupulous producers.objectives: the aim of this study was using pcr assay todetect cow milk in labeled sheep milk, sheep yoghurt, andlighvan cheese (a traditional ripened cheese produced fromsheep's milk). methods: the assay utilized primers target...

1MicroRNAs (miRs, miRNAs) play central roles in gene regulation. Previously, we2reported that miRNAs from pasteurized, store-bought bovine milk have biological3activity in humans. Here we assessed the effects of milk processing, storage, somatic cell4content, and handling by consumers on the degradation of miRNAs in milk; we also5quantified miRNAs in dair...

Milk is a highly consumed product worldwide mainly because of nutrient content, but this rich composition associated to pH and water activity makes the milk an ideal medium for microbial growth. The thermal process is usually applied to guarantee microbial stability of milk, however, the heat promotes undesirable changes in the milk sensory and nutritional characteristics. Therefore, recent res...
