the ratio of ω-6: ω-3 is connected to the higher risk of non-communicable diseases, thus this ratio is becoming more important than quantity of ω-6 and ω-3 in human nutrition. in countries like iran, cow’s milk is mainly produced in rural area and less in conventional systems. the lactating cows reared in rural and conventional farms are different in terms of nutrition, daily yields, and propor...

Milk coagulation properties (MCP) are fundamental in cheese production, particularly in countries where a large amount of milk is destined to cheese industry. Several studies have demonstrated the role of MCP on cheese yield and quality. Lasting years, a general worsening of MCP at the herd and animal level has been detected. The coagulation of milk is influenced by several factors such as type...

The aim of this study was to investigate the occurrence, antibiotic susceptibility profiles, and virulence genes determinants of S. aureus isolated from milk obtained from retail outlets of the North-West Province, South Africa. To achieve this, 200 samples of raw, bulk and pasteurised milk were obtained randomly from supermarkets, shops and some farms in the North-West Province between May 201...

Mycobacterium avium subsp. paratuberculosis (MAP) in milk of bovine origin is suspected of being implicated in Crohn's disease in humans. Milk can be contaminated via direct excretion of MAP in milk or indirectly via fecal contamination of the milk. This study aimed at estimating the level of MAP in farm bulk tank milk and simulating the effect of direct and indirect contamination with MAP. The...

When udders were washed before milking, a post milking teat-dipping with a 5,000 mg available iodine/l iodophor induced an iodine residue of 33 to 54 micrograms l/kg in milk. The iodine contents of the first jets of milk were 1.08 to 8.27 times higher than those of average milk. However, the bulk of iodine residues in milk seemed to be an iodine transfer across teat skin to milk. From these dat...

Over 30 dairy companies use the ADAS Milk Laboratory to provide them with individual farm bulk milk quality. The SCC information that this provides is representative of the industry and taken from a large range of dairy farms. Since 1994 (de-regulation) the ADAS Milk Laboratory results have shown a steady decline in SCC. From 2000 the SCC have unfortunately began to rise with an acceleration seen.

The objectives were to identify the source of Listeria monocytogenes in bulk tank milk (BTM), and to assess characteristics of Petrifilm Environmental Listeria (PEL) for detection of this pathogen in farm samples. Environmental and milk samples were collected from a dairy during two sampling periods. Follow-up samples of daily BTM and milk filters were collected. Isolates of L. monocytogenes we...

Milk samples of 12 Danish dairy herds were collected 3 times during an 11-mo period and tested for Coxiella burnetii DNA by real-time PCR, detecting the IS1111 element, and for the presence of antibodies against the bacterium by ELISA. On average, 25% of 1,514 samples were seropositive and 32% were positive for C. burnetii DNA. Among the 485 DNA-positive samples, quantification cycle values ran...

The effects of sheep alpha s1-casein CC, CD and DD genotypes on milk composition and cheese yield were studied. Processed bulk milk was collected from three groups of 15 ewes, carrying alpha s1-casein CC, CD and DD genotypes. CC milk was higher in casein content than CD or DD milk (+3.5 and +8.6% respectively), and had a higher protein: fat ratio and a smaller casein micelle diameter. In additi...
