Abstract


The observations were made, through a year, at SD Timisoara on cows fromHolstein-Friesian and Fleckvieh breed. The puerperal period was observed, theincidence of the endometrites was recorded and there were calculated tworeproduction parameters: the Insemination Index (Ig) and the Uterine Reposeduration (UR) (Open days). The Insemination Index (service/conception) (Ig)represents the mean number of artificial inseminations performed in order to obtaina pregnancy. Uterine Repose represents the time interval, in days, from calving untilthe fecund insemination. The Uterine Repose has two components: VoluntaryWaiting Period (VWP) (time interval from calving until the introduction of thefemale to reproduction) and Service Period (SP) (time interval from the end of theVWP until the fecund insemination). There were noticed that the incidence of theuterine infections were significant higher (p<0.05) at cows from Holstein-Friesianbreed (63.3%), compared to the cows from Fleckvieh breed (41.3%). TheInsemination Index was significant lower (p<0.05) at cows without uterine infections(1.9), compared to the cows with uterine infections (2.5). The mean duration of theUterine Repose was significant lower (p<0.05) at healthy cows (114.7 days),compared with cows with uterine infections after calving (182.2 days). It seams thatthe cows from Fleckvieh breed are more resistant to the exploitation conditions formilk production than compared with cows from Holstein-Friesian breed.
