A simple and short HPLC-UV screening method for the determination of residues for seven NSAIDs (carprofen, diclofenac, flunixin, meloxicam, phenylbutazone, tolfenamic acid, vedaprofen) and their three metabolites (4-methylaminoantipyrine, 5-hydroxyflunixin, oxyphenbutazone) in cow’s milk has been developed. The sample preparation was based on liquid-liquid extraction with acetonitrile in the pr...

The fate of ivermectin (IVM) residues was studied throughout the processing of daily bulk milk from 30 ewes (taken up to 33 d following subcutaneous administration of 0.2 mg IVM/kg b.w.) in the following milk products: yoghurt made from raw and pasteurized milk; cheese after pressing; 30- and 60-day ripened cheese; and whey, secondary whey and whey proteins obtained after cheese-making (albumin...

The Bos indicus Vechur breed cow milk is known for its medicinal value and the breed is listed under the category of critically maintained breeds by the Food and Agriculture Organization. The lactoferrin protein in milk is known for its nutritional value. Gene polymorphisms have been reported for Bovine lactoferrin. Mutations in the evolutionarily conserved sites tend to impair protein function...

A cross sectional study was conducted during October and November 2006 on 69 smallholder dairy farms with lactating cows in Mvomero and Njombe districts Tanzania, to determine the prevalence of mastitis and to assess the milk quality on the study farms. Clinical mastitis was investigated using clinical changes of udder and milk at animal level. Cow-side California Mastitis Test (CMT) and microb...

Human milk is the best source of nutrition for infants. Breast milk contains the optimal balance of fats, carbohydrates, and proteins for developing babies, and it provides a range of benefits for growth, immunity, and development. Unfortunately, breast milk is not pristine. Contamination of human milk is widespread and is the consequence of decades of inadequately controlled pollution of the e...

Protein lactosylation is a significant modification that occurs during the heat treatment of dairy products, causing changes in proteins' physical-chemical and nutritional properties. Knowledge detailed information on milk proteins under various treatments important for selecting appropriate thermo-processing identifying markers to monitor load products. In present study, we used proteomics tec...

A liquid chromatographic-tandem mass spectrometric (LC-MS/MS) multi-residue method for the simultaneous quantification and identification of 38 residues of the most widely used anthelmintic veterinary drugs (including benzimidazoles, macrocyclic lactones, and flukicides) in milk and liver has been developed and validated. For sample preparation, we used a simple modification of the QuEChERS met...

The pesticide trichlorfon is readily degraded under experimental conditions to dichlorvos. A method has therefore been developed by which residues of trichlorfon in milk are determined as dichlorvos, using gas chromatography with μ-electron capture detection. The identification of dichlorvos was confirmed by mass spectrometry. Milk was extracted with acetonitrile followed by centrifugation, fre...
