Tejelő szarvasmarhák egyes termelési és szaporodásbiológiai mutatóinak biometerológiai összefüggései

Abstract

In our research we studied the biometeorological effects on production and reproduction variables in a large scale dairy cow herd in Hungary. Data concerning the stock was gained from the database of the managing system of the dairy cow farm from May 1997 to March 2015. In monitoring the effects of fronts we used the ERA-Interim data gained from the European Centres for Medium range Weather forecasts (ECMWF), and in the analysis of heat stress we used data from the meteorological station in Pápa.
