Zusammenfassung

The aim of this paper is to establish support systems which would resolve the supervision and control of the management plan, ensure sustainability of quality products and create conditions for stability of income. The study was carried out over five hunting seasons (2004/2005 to 2008/2009). Research area was hunting ground „Podunavlje - Podravlje XIV / 9," lowland type, altitude 65 to 120 m, situated between the rivers Danube and Drava in Baranja. The total area within the boundaries of the hunting ground is 26,810 ha. Field data are classified into the following age and sex classes: calves, yearling females, hinds, yearling males, males 3, 4 and 5 years old, males 6, 7 and 8 years old, and males 9 years old and older. The observed parameters were: the net body weight, fertilization, fetus length and weight, the length of the antler branches, the length of the third tine, the number of tines, weight and value of the antlers in the CIC. Statistical data processing and distribution of values of the parameters were established for each age and sex class. The values of parameters are the selection standards that should be reached by deer of every age and gender, or standards within which the values of certain parameters should be in order to enable support with which, together with selection shooting, clear standards can be set for the observed population. Parameter selection for calves is body weight. The accuracy of selection is monitored according to net body weight. Arithmetic mean of net body weight of calves is 37.77 kg. Yearling females were selected on estimates of body mass. A kind of threshold net body weight was established that is required for mating and successful fertilization. Net body weight that yearling females must achieve in order to be fertilized is 55 kg to 60 kg. Arithmetic mean of net body mass for yearling females is 53.13 kg, and the fertilization rate 47%. For hinds it is essential to maintain body weight around the mean body weight, while the fertilization rate remains above the value ...
