  1. 1. Relationship between Natural Antibody levels and Somatic Cell Count in Dairy Cattle

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Jyothy Sreedharan; [2011]
    Nyckelord :Mastitis; somatic cell score; Natural antibodies; relationship; heritability;

    Sammanfattning : At present mastitis in dairy cattle is detected by using somatic cell count and various bacterial diagnostic tests. Still it is difficult to understand the exact health status of the animal by mere observation of the test results, since there maybe presence of sub-clinical cases. LÄS MER
