BACKGROUND Nicotinamide riboside (NR) is a recently discovered NAD(+) precursor vitamin with a unique biosynthetic pathway. Although the presence of NR in cow milk has been known for more than a decade, the concentration of NR with respect to the other NAD(+) precursors was unknown. OBJECTIVE We aimed to determine NAD(+) precursor vitamin concentration in raw samples of milk from individual c...

Bounded rationality is an especially appropriate framework for organic dairy adoption decisions as it recognizes internal and external constraints which are critical in understanding complex farm decision making. Farmers use of, and access to, information is examined using interview data gathered from organic, conventional, managed graziers, and Amish dairy farmers in Southwestern Wisconsin at ...

A study was conducted to evaluate the short-term effects of feeding two dietary Se sources at various Se levels on the transfer of Se to the dam's milk and nursing pig. Six dietary treatments were arranged in a 2 x 2 factorial arrangement with two additional treatments in a randomized complete block designed experiment. Inorganic (sodium selenite) or organic (Se-enriched yeast) Se sources were ...

This study of UK retail milk identified highly significant variations in fat composition. The survey, conducted over 2 yr replicating summer and winter, sampled 22 brands, 10 of which indicated organic production systems. Results corroborate earlier farm-based findings considering fat composition of milk produced under conventional and organic management. Organic milk had higher concentrations ...

Introduction Since the 1970s and 1980s, private label products (also known as store brands) have seen great improvements in product quality and large gains in market share. Once considered a low-quality, low-price alternative, some private label products evolved to compete with high-quality, market-leading brands, including organic brands (Burt, 2000). Citing a study in 2006 produced by the Pri...

The aim of this study was to investigate the effects of production systems and milk collection periods on the somatic cell count (SCC), some microbiological properties, total aerobic mesophilic bacteria (TAMB), coliform, Staphylococcus aureus (S. aureus), yeast and mould) and antibiotic residue of milk; in Turkey. Milk samples were collected from 9 conventional farms and 9 organic farms during ...

Background: Nicotinamide riboside (NR) is a recently discovered NAD precursor vitamin with a unique biosynthetic pathway. Although the presence of NR in cowmilk has been known for more than a decade, the concentration of NR with respect to the other NAD precursors was unknown. Objective:We aimed to determine NAD precursor vitamin concentration in raw samples of milk from individual cows and fro...

Copper (Cu) plays an essential role in the human and animal body system. One of the most important sources of Cu is milk. The purpose of this study was to determine the effect of different doses of injection of inorganic Cu and organic Cu as Cu-arginine and Cu-lysine on Cu concentrations of milk in the lactating Zandi’s ewes. This experimental research involved 54 lactating Zandi’s ewes collect...

The objective of this study was to evaluate the presence of methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococcus spp. in bulk tank milk samples from 288 organic and conventional dairy farms located in New York, Wisconsin, and Oregon from March 2009 to May 2011. Due to recent publications reporting the presence mecC (a mecA homolog not detected by traditional mecA-ba...

Research on environmentally related chemical contaminants in breast milk spans several decades and dozens of countries. The ability to use this research as an environmental indicator is limited because of a lack of consistent protocols. Data on xenobiotics in breast milk are influenced by choices in sample selection, sample pooling, analysis, and reporting. In addition, most studies have focuse...
