Evaluation of changes in milk composition in winter and summer period and its influence on rennet coagulation time of milk

Popis výsledku v původním jazyce

Objective of this research was evaluation of changes in milk composition in winter and summer period and its influence on rennet coagulation time of milk. During the period of 24th January 2013 to 11th March 2013 (winter period - WP; n=47) and 30th June2013 to 30th September 2013 (summer period - SP; n=47) were analysed bulk milk samples obtained in herd of Czech Fleckvieh cows from farm GenAGRO Říčany, a.s. (GPS 49°12'32.319"N, 6°23'42.666"E). Monitored parameters were: average diurnal temperature(ADT), content of fat, protein, lactose, Ca, Mg, Cl, somatic cell count, chloride-lactose ratio, titratable acidity,rennet coagulation time (RCT). Between WP and SP were found in ADT, RCT and content of Ca statisticallyvery highly significant differences (P0.001) and in content of Cl statistically significant difference (P 0.05).In the evaluation of effect of ADT and milk composition on RCT was in WP found statistically highly significant (P 0.01; r = -0.38) correlation relationship between
