Increased genetic susceptibility to mastitis has accompanied the rapid genetic increase in
milk yield, and genetic selection for mastitis resistance should be considered. Somatic cell …

The literature on somatic cell count (SCC) is reviewed with particular emphasis on genetic
and phenotypic parameters and the suitability of the trait as an indirect means of reducing …

Data from 274 Dutch herds recording clinical mastitis (CM) over an 18-mo period were used
to investigate the effect of pathogen-specific CM on the lactation curve for somatic cell count …

Test day models were used to estimate lactation curves for milk, fat, protein, fat percentage,
and protein percentage and to study the influence of age, season, and herd productivity on …

Heredity influences both clinical mastitis and somatic cell score. Intramammary infection is
the major cause of elevated somatic cell score. A nationwide program of genetic evaluation …

Abstract Between January and July 1992, 8403 monthly test day records were obtained from
3202 ewes from 22 Churra dairy flocks in the Castilla-León region of Spain. Variables …

A total of 3119 test day records for milk yield, somatic cell count (SCC), and contents of fat,
protein, casein, serum protein, lactose, and total solids were obtained weekly from 155 …

Sudden dry-off is an established management practice in the dairy industry. But milk yield
has been increasing continuously during the last decades. There is no information whether …

The aim of the present investigation was to study the underlying causes of noncoagulating
(NC) milk. Based on an initial screening in a herd of 53 Danish Holstein-Friesians, 20 …

The main objectives were to analyze milking-to-milking variability in milk yield, fat and
protein percentages, and somatic cell count (SCC). Additional objectives were to investigate …
