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...

To determine the impact of reducing the current legal limit of 750,000 cells/ml for somatic cell count (SCC) in US market milk, data were examined from 539,577 herd test days for Dairy Herd Improvement herds on test during 1996 and 1997. Somatic cell scores for individual cows were converted to SCC. The SCC for each cow was weighted by milk yield and used to compute herd mean on test day. The m...

The present study was carried out to investigate the effects of somatic cell counts (SCC), differential SCC (macrophage (MAC), lymphocyte (LYM) and polymorphonuclear leukocytes (PMN)), number and stage lactation on milk composition in camel and cow milk. Camel milk appeared to contain significantly (P

The objective of the present study was to explain the genetic and phenotypic relationship between test-day somatic cell count and score (SCC& SCS), with daily milk yield in Gabali and Aradi Saudi goat using the random regression animal model. The total number of production records included in the present study was 2021 dairy records. 942 dairy records for Aradi goats and 1079 dairy records for ...

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...
