Abstract

Aim of the present study was to establish influence that lactation order has on the number of somatic cells from raw milk in Romanian Black and White breed cows. The study was carried out on 125 lactations of 92 cows. Data were statistically processed using Microsoft Statistica program, and by variance analysis Anova/Manova. Results obtained shown that primiparous cows had a somatic index smaller (5.29), for this index corresponds a lower number of somatic cell/ml of 195000. In multiparous cows, during the fourth lactation, the greatest somatic index was registered (5.81), value that corresponds with a concentration of somatic cells in milk/ml of 646000.
