  Cattle behaviour on rangeland depends on external factors, such as grass allowance and quality, temperature, net solar radiation, distance from water-source, wind speed and direction, air pressure changes and the applied breeding technology. Our research is based on previous empirical observations and modern methods to analyze the behaviour of the Hungarian Grey Cattle. Today it is crucial to use cost-effective solutions in modern beef cattle farming therefore we introduce a cost-efficient method to study and follow cattle herds. We are studying relation between traveled daily distance and air pressure. The various weather fronts influence behavioural characteristics and traveled daily distance. According to our hypothesis, the pressure-change and the wind direction has significant effect on cattle activity on pasture. As the different air masses alter the barometric conditions and unbalance the neuroendocrine system, indirectly cause relaxed or agitated behaviour

  This paper presents economical importance of white lupin /Lupinus albus/. It is an important task as exceptional effectual green manure, that shows VIII treatment’s results of Westsik long-term field experiment. Content of white lupin seed is similar than content of soybean. By the forrage examination the soybean can substitute whit white lupin seed in 40%. The main problem of the production of lupin seed is the want of long term herbicides. For the solve of this problem to find herbicides which are efficiant for 80-100 days. First we have try 26 different herbicides.

  Ethology, the research field of animal behaviour, during the past half century developed into an independent science and became more important in recent years as the farming industry has turned toward quality production. Farm animals respond for every environmental factor. Essential to know the answers to avoid unpleasant economic consequences. Based on the shepherds’ experience, this science has merged with modern technology, constantly expanding and searching new methods. According to the literature the article summarizes the observation methods in cattle grazing. This paper introduces the beginnings and shows the future trends. Finally we share personal experiences as the Hungarian Grey cattle grazing behaviour at conditions of Hortobágy, Hungary.
