A multilaboratory trial for determining ceftiofur-related residues in bovine and swine kidney and muscle, and bovine milk was conducted following regulatory guidelines of the U.S. Food and Drug Administration, Center for Veterinary Medicine. The methods convert all desfuroylceftiofur-related residues containing the intact beta-lactam ring to desfuroylceftiofur acetamide to establish ceftiofur r...
ATP-binding cassette transporter ABCG2 [breast cancer resistance protein (BCRP)] is a member of the ABC transporter superfamily that actively extrudes xenotoxins from cells and is a major determinant of the bioavailability of many compounds. ABCG2 expression is strongly induced during lactation in the mammary gland and is related to the active secretion of drugs into the milk. The presence of d...
Mastitis causes huge economic losses to dairy farmers worldwide, which largely negatively affects the quality and quantity of milk. decreases overall milk production, degrades quality, increases because being discarded, production costs due higher treatment labour premature culling. This review article discusses mastitis with respect its clinical epidemiology, pathogens involved, losses, basic ...
Milk, due to its high nutritional content, is an excellent medium for supporting growth of diverse group microorganisms, many which produce beneficial compounds like bacteriocins. Class I bacteriocins, called lantibiotics, are ribosomally synthesized, post-translationally modified peptides containing unusual amino acids, such as dehydrated and lanthionine residues with antibacterial activities....
BACKGROUND Tylosin and Josamycin are macrolide antibiotics. They are used in the treatment of pneumonia, arthritis and mastitis in cattle, and mycoplasma infections in poultry. The incorrect use of antibiotics has lead to the presence of antibiotic residues in foods. The residues cause toxic effects on consumers. RESULTS A simple and sensitive method was optimized and validated for the analys...
background: microbiological and chemical qualities ofmilk are among the most important issues in public health.objectives:although there are a few published studies whichhave been conducted in south east of iran this study wasperformed to investigate quality of raw milk delivered to a dairyindustry company kerman province. methods:atotal of 109raw milk samples were collected at the time of deli...
Dairy product quality monitoring begins at the farm and ends in hands of consumer. Raw milk must also meet other standards; it should be free drug residues, added water sediment, contaminants abnormalities. In our researches, is taken somatic cells count, number bacteria Aflatoxins as indicators raw from Ov?e Pole region period January-June, 2018. For needs this research, an analysis was made 1...

Human milk oligosaccharides, representing the third largest fraction of human milk, have been assigned important protective functions for newborns acting as bifidogenic substrates or as inhibitory agents towards pathogens. Using high-pH anion-exchange chromatography and an enzyme test kit, twenty oligosaccharides and lactose were determined in milk samples of German women from days 3 to 90 post...
