Interaction of somatic cell count and quarter milk flow patterns.
Milk flow parameters at udder and quarter levels were studied in relation to somatic cell count (SCC) and other risk factors for mastitis (bimodality, duration of decline, and duration of overmilking phase). Thirty-eight Holstein cows in their first to sixth lactations were investigated during 10 mo of lactation. Monthly milk samples were collected for SCC during morning milking. Quarter and ud...
متن کاملAssociation between bovine lactoferrin gene variant and somatic cell count in milk based on EcoRI restriction site
Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...
متن کاملBovine Udder Quarter Milk in Relation to Somatic Cell Count Focus on Milk Composition and Processing Properties
The dairy industry requires raw milk of high quality in order to produce milk products of high quality and quantity. Mastitis is one of the most prevalent and economically important production diseases in dairy cattle. It causes increased somatic cell count (SCC), deteriorated milk composition and consequently altered processing properties of milk. Altered milk composition due to mastitis often...
متن کاملThe Relationship of Milk Somatic Cell Count to Milk Yields for Holstein Heifers After First Calving
The contribution of a dilution effect to the relationship between milk yield and milk SCC was investigated using data from 24 Holsteins during the first 75 d after first calving. Bucket and quarter milk SCC were collected at weekly intervals. Individual milk weights were obtained at milking, and samples were obtained for determination of SCC. The milk weights at the corresponding a.m. milking o...
متن کاملDifferential leukocyte count method for bovine low somatic cell count milk.
Whereas many differential leukocyte count methods for high somatic cell count (SCC) milk from mastitic cows are available, only a few have been developed for low SCC milk. We have developed a flow cytometric differential leukocyte count method for low SCC milk. The procedure consists of 1) 1.5 ml of diluted milk sample (30%, vol/vol dilution with PBS), 2) centrifugation, 3) leukocyte labeling w...
