Abstract


One of the main objectives in dairy cows exploitation is to guarantee food security and safety of the population, a desideratum achieved through better milk quality and better control of production in all aspects imposed by the health and welfare of animals from which milk is obtained. The purpose of this sciencific paper is to highlight the status of mammary gland health in a population of Friesian-Black Spotted breed based on the main traits of milk quality, with particular reference to somatic cell counts as the main indicator of subclinical mastitis. The research was conducted in 2014 within the farm S.C. “Modern Farm†S.R.L., located in Jucu village. The individual analysis of Holstein Friesian milked cows was performed, the main indicators of milk production were analysed both quantitatively, based on production obtained daily, and especially qualitatively, based on seven controls with individual sampling from all milked cows at the date of control. Qualitative analysis of 1,391 milk samples highlighted the fact that the somatic cell count in milk obtained from cattle included in this study  recorded an average value of 390.54 ± 11.16 cells/ml x 103 with the variability between controls of 314.94 ± 28.93 and 482.36 ± 91.12 cells/ml x 103. Regarding the fat content, the average values was 4.19%, 3.63% for protein content, a pH value of 6.56 and the values of  urea was 20.09 mg/dl. Individual analysis also revealed some cows with subclinical mastitis, which were milked separately, verified and monitored supplementarily in order to reestablish udder health and to prevent the occurrence of clinical mastitis, which can compromise the mammary gland.
