Factors affecting productivity indicators of beef cattle
 KRÁLOVÁ, Alena
The aim of breeding suckler cows is same as the aim of any other activity- achieving the best results. Aspects like the quality of food, the corresponding energy value and correct feeding in terms of health and production, play an important part in nutrition. The concentration of energy of feed, within the group observed, for suckler had value of 5.4 MJ NEV. Preserved feed without undesirable content of butyric acid was graded as very good accordingly to the class of quality. The biggest cost item is the cost of feed. In a particular company, the price of feed for a cow with a bred calf represents 42% of total costs. The revenues from breeding of cattle are based on incomes from calves sales or fattening of them and their subsequent sale. An important part of an economic efficiency is a good fertility of cows. In a particular farm, the fertility for 2013 was 89% and 90% for 2014.
