Abstract
Abstract. This study aimed to characterize milk coagulation properties (rennet
coagulation time, curd-firming time and curd firmness 30 min after rennet
addition to milk) and major mineral contents (Ca, Mg, P, K and Na) in
Pinzgauer dual-purpose cattle breed. The edited dataset consisted of
7763 milk observations from 851 cows reared in 60 herds in the Alpine area of
Bolzano province (Italy). Data were analysed through a linear mixed model
which included stage of lactation, parity and their interaction as fixed
effects, and cow and herd test date as random effects. Rennet coagulation
time, curd-firming time and curd firmness 30 min after rennet addition to
milk averaged 22.66 min, 5.53 min and 16.79 mm, respectively. The most
abundant minerals were P (1495 mg kg−1) and Ca (1344 mg kg−1),
and the least abundant Mg (141 mg kg−1). Compared to their older
contemporaries, early-lactating younger animals yielded milk that was more
favourable for cheese production (i.e. with shorter coagulation time and
stronger curd firmness). Mineral contents were lower in milk of primiparous
than multiparous cows, except for Na. Moreover, Ca, Mg, P and Na contents
decreased from parturition to peak of lactation and increased thereafter,
except for K, which exhibited an opposite trend. Our results showed that
Pinzgauer breed produced milk with better coagulation properties and mineral
content, from a technological point of view, in first than later parities and
in early than late lactation. The characterization of milk coagulation
properties and mineral content in autochthonous breeds is important to
increase their value and marketability of their products.
