Název v původním jazyce

Real consumption of NEL and PDI in comparison to calculated values of requirement measured on dairy cows in condition of Czech Republic

Popis výsledku v původním jazyce

The aim of work was to compare the real consumption of NEL and PDI with calculated values of requirement measured on dairy cows. Two cows were fed twice a day (7.00 and 17.00 h), roughage part of ration (maize silage, meadow hay) was offered ad libitum,mixture was dosed according to average milk yield recorded in previous week (0.50 kg of mixture/kg of milk). Daily ration was optimalized for 105 % of NEL reqirement and for 95 % of PDI requirement. One period lasted 42 days. The calculation of NEL and PDI requirement were done according to milk yield, milk fat percentage, live weight and phase of lactation. Calculation of brutto (BE) and metabolizable (ME) energy was based on results of organic analyses. It was found out, that the real consumption of NEL was slightly above the calculated requirement. Real consumption of PDI was in a good agreement with calculated requirement.
