Abstract
Subclinical mastitis in dairy animals remains a hidden threat to the dairy farmers as it does not present apparent signal. One of the
techniques used to monitor the level or occurrence of subclinical mastitis in herds or individual cows or quarters is to determine the
somatic cell count (SCC) of milk samples. The somatic cells of milk are mainly leukocytes, which include macrophages, lymphocytes
and neutrophils which are involved in the defence against invading microorganisms. Thus, the number of SCC in milk sample is an
indicator of subclinical mastitis. The present study was undertaken to compare the health status of lactating dairy cows of organized
(ILFC, VCRI, Namakkal) and unorganized dairy farms, respectively at different stages of lactation. The midstream milk samples from
the dairy cows were analyzed as per the protocol mentioned in the ABT-SCC Quick count kit (TANUVAS). The results were read and
compared with the score card provided with the kit. The SCC of animals in organized farm were in the range of 1,00,000 to 2,00,000
per ml of milk and among the animals in unorganized farm, the animals in late stage of lactation had SCC of 3,00,000 per ml and other
animals had 1,00,000 per ml. The somatic cell counts of the animals under study were within the agreed limit for subclinical mastitis i.e.,
5,00,000 per ml of milk. The result of the present study reveals that regardless of the management practices followed in organized and
unorganized farms the animals are acquainted to their environment and generate resistance and are free from subclinical mastitis.
