Abstract
In the lactation cycle of dairy cows, the dry off is a critical period of rest
for the udder, in order to optimize milk production in the next lactation.
Lactoferrin (LF) is an iron-binding protein normally excreted in cow’s
milk and it is one of the natural protective factors having the ability to
inhibit the growth of mastitis-causing pathogens. The objective of this
research was to determine whether LF concentration in the milk is
increased at drying off period. Quarter milk samples (n=40) from
clinically healthy Holstein-Friesian cows were taken. Milk samples were
collected one week prior to dry off and on the day of dry off. The milk
samples were analyzed for physicochemical properties, somatic cells
(SCC) and concentrations of lactoferrin. The mean LF concentration in
the milk was found to increase significantly (p<0,05) from 2.977,28
μg/mL, one week prior to dry off to 4.529,07 μg/mL on the day of drying
off process.
