A L Van Eenennaam, A E Young
Products such as meat, milk, and eggs from animals that have consumed genetically engineered (GE) feed are not currently subject to mandatory GE labeling requirements. Some voluntary "non-genetically modified organism" labeling has been associated with such products, indicating that the animals were not fed GE crops, as there are no commercialized GE food animals. This review summarizes the available scientific literature on the detection of dietary DNA and protein in animal products and briefly discusses the implications of mandatory GE labeling for products from animals that have consumed GE feed...

Mastitis is the most frequent and costly disease of lactating animals and is associated with a significant reduction in milk yield, increased cost and culling. Early and specific antibiotic based treatment reduces the severity of the disease. Over the years the extensive use of antimicrobials has led to increase antimicrobial resistance. The present study was designed to investigate the prevalence of microorganisms responsible for mastitis and their antimicrobial resistance pattern. A total of 282 milk samples were collected from different animal species (sheep, cows and goats) with clinical mastitis...

Impaired quality due to a high content of free fatty acids (FFA) and off-flavors has caused challenges in the development of Norwegian goat milk products. The present study aimed to examine the effect of lipid-supplemented concentrates on milk fat content, fatty acid composition, FFA, lipoprotein lipase activity, sensory properties, and size of milk fat globules of goat milk. Thirty goats assigned to 3 experimental groups were fed different concentrates from 60 d in milk (DIM) until late lactation (230 DIM)...

Increasing evidence on goat milk and the health benefits of its derived products beyond its nutritional value show its potential as a functional food. In this study, goat milk fractions were tested for their total antioxidant capacity using different methods (ORAC, ABTS, DPPH and FRAP), as well as their angiotensin-I-converting-enzyme inhibitory and antimicrobial (against Escherichia coli and Micrococcus luteus) activities. Different whey fractions (whey, cation exchange membrane permeate P and retentate R) of two fermented skimmed goat milks (ultrafiltered goat milk fermented with the classical starter bacteria or with the classical starter plus the Lactobacillus plantarum C4 probiotic strain) were assessed...

Tamr (dried dates) has a high sugar content, essential vitamins, and high nutrient density. Dairy products still are the most typical carriers of probiotic bacteria. Six treatments of bio-rayeb milk were manufactured from goat's milk fortified with 5%, 10%, 15%, 20%, and 25% Tamr using ABT-5 culture. Rayeb milk containing tamr had lower pH and fat and higher carbohydrate, total solids, dietary fiber, ash, total protein, water-soluble nitrogen, and total volatile fatty acids. Mixing tamr with bio-rayeb milk increased nutritional value by decreasing saturated fatty acids and increasing unsaturated fatty acids, oleic, linoleic, α-linolenic acids, and antioxidant activity values...

A selective and rapid method has been developed to determine 15 antibiotic residues (eight tetracyclines and seven quinolones) in milk samples by capillary zone electrophoresis coupled with quadrupole time-of-flight mass spectrometry (CZE-Q-TOF-MS). The use of this hybrid mass spectrometer allowed obtaining full scan and full MS/MS spectra for quantification/confirmation purposes in a single run. In addition, solid phase extraction (SPE) using the new Oasis PRiME HLB cartridge was proposed for the extraction, achieving excellent results in terms of sample throughput...

SCOPE: Breastfeeding is associated with reduced risk of infection, immune mediated disorders, obesity and even cancer. Recently it was found that breast milk contains a variety of microRNAs (miRNAs) in the skim and fat layer that can be transferred to infants, and appear to play important roles in those biological functions. METHODS AND RESULTS: This study applied Next Generation Sequencing and quantitative real time PCR analysis to determine the miRNA expression profile of the skim and fat fraction of human, goat, and bovine milk as well as infant formulas...

The exact influence of caprine arthritis encephalitis virus (CAEV) infection on blood and milk polymorphonuclear leukocytes (PMNLs) and monocyte/macrophages of goats remains unclear. Thus, the present study sought to explore the blood and milk PMNL and monocyte/macrophage functions in naturally CAEV-infected goats. The present study used 18 healthy Saanen goats that were segregated according to sera test outcomes into serologically CAEV negative (n=8; 14 halves) and positive (n=10; 14 halves) groups. All milk samples from mammary halves with milk bacteriologically positive outcomes, somatic cell count ≥2×10(6)cellsmL(-1), and abnormal secretions in the strip cup test were excluded...
