ORTIZ Z., César  and  VERA A., Ricardo. Recuento de células somáticas en hatos lecheros de diferente nivel tecnológico en Arequipa. Rev. investig. vet. Perú [online]. 2006, vol.17, n.2, pp.104-107. ISSN 1609-9117.

The objective of the present study was to evaluate the Somatic Cell Count (SCC) in milk in dairy herds of the Arequipa region. Milk samples were collected every two weeks throughout the year 2005 from 15 dairy farms located in the irrigated area of Majes, Santa Rita, and La Joya districts. Milk farms were stratified according to their technological level as high, medium, and low. The average SCC in the study was 505 x 103 ± 150 x 103 cel/ml, and for high, medium and low technological level were 353, 559 y 603 x 103 cel/ml, respectively. Significant differences were found between levels of technology (p<0.05). The study showed an increase in SCC as the level of technology in the herd decreased.
