Abstract


The study was carried out on 9 Romanian Black and White primiparous cows. The aim of this study was todetermine some aspect of nutritional behaviour of the cows. During the experiments, the following behaviour aspectswere determined: interruption number and their duration in the feed consumption time. Results showed that theadministration order of forages had an influence on the interruptions number, which was 0.74 less for hay in fibroussucculentorder (O1). For silage, the interruption number was 0.42 higher in fibrous-succulent order (O1). Betweenportion 1 (P1) and portion 3 (P3), the significant difference (p<0.05) was for interruptions duration, duringconsumption silage, in favour portion P1. Distinct significant differences (p<0.01) was observed for the interruptionnumber during consumption silage (0.95 sec. higher in P1 than in P3), for interruption duration (5.96 sec. higher inP1 than in P3). Between P2 and P3, significant difference (p<0.05) was observed for interruptions number duringconsumption silage and for average interruptions duration during consumption beet in favour to portion P2.Regarding the number of feedings per portion, always the differences were higher in the second feeding F1 than inthe first feeding F2.
