Název v původním jazyce

Real consumption of NEL and PDI measured on dairy cows in comparison to requirement values calculated according to INRA.

Popis výsledku v původním jazyce

The aim of the work was to compare real consumption of NEL and PDI and calculated values of requirement measured on dairy cows according to french system INRA. Two cows were fed twice a day (7.00 and 17 h), roughage part of ration (maize silage, meadow hay) was offered ad libitum, mixture was dosed according to average yield of previous week (0.50 kg of mixture/kg of milk). Daily ration was optimalized for 105 % NEL requirement and for 95 % PDI requirement. One period lasted 42 days. The calculation ofrequirement of NEL and PDI were estimated according to milk yield, fat content in milk, live weight and stage of lactation. Parameters of feeds (UFL, UEL a PDI) were calculated using PrévAlim tool of INRAtion software. The difference between calculated requirement according to INRA and real consumption of NEL was probably caused by unrealistic high content of NEL in rouhage part of ration (assigned by PrévAlim).
