Milk samples were collected from quarters of 35 cows with subclinical mastitis (California mastitis test [CMT] positive and somatic cell counts [SCC] >500,000 cells/ml in individual quarter foremilk), as well as from 37 healthy controls. Compared to the levels observed in milk from healthy quarters, milk from quarters with subclinical mastitis showed elevated sodium (91.97 vs 52.93 mg/dl), chlo...

genetic and phenotypic parameters related to production traits, udder conformation and somatic cell count for the iranian holstein cows were estimated. monthly records of somatic cell counts (scc) were primarily transformed into somatic cell scores (scs) and the the average level of lactation period, with correction for milk volume, was calculated. by use of these estimates an udder health inde...

the objective of this study was to analyze the association of somatic cell score (scs) with milk, fat and protein yields across parities. records of production traits and somatic cell counts (scc) from first, second and third parity that were collected by the animal breeding center of iran from 1993 to 2010 were used.all animals were grouped into six classes according to scc and production trai...

this experiment was aimed to study the association between the dgat1 k232a polymorphism and milk production traits and somatic cell score (scs) in iranian holstein dairy cows. the records of 408 animals from five dairy herds were randomly identified and then genomic dna was extracted from blood using the modified-salting method described by miller. rflp-pcr was performed to obtain all the polym...

Nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. Analyses included total nitrogen (TN), non-casein nitrogen (NCN), non-proteinnitrogen (NPN), casein nitrogen (CN) and proteolysis index (PI). Yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°C. TN, CN and PI contentsof yoghurt milk samples with high Somatic Cell SC...

Typically, central milk recording data from dairy herds are recorded less than monthly. Over-fitting early in lactation periods is a challenge, which we explored in different ways by reducing the number of parameters needed to describe the milk yield and somatic cell count of individual cows. Furthermore, we investigated how the parameters of lactation models correlate between parities and from...

Somatic cells are an important component naturally present in milk, and somatic cell count is used as an indicator of udder health and milk quality. The role of somatic cells in dairy processes and products is ill-defined in most studies because the role of these cells combines also the concomitance of physicochemical modifications of milk, bacterial count, and the udder inflammation in the pre...
