Research on Drinking Behavior in the Feed Consumption Time in Romanian Black and White Primiparous Cows

Silvia Erina

Abstract


The study was carried out on 9 Romanian Black and White cows in their first one hundred days of lactation. The aim

of this study was to determine some aspect of drinking behavior of the cows  in the feed consumption time. The forages (hay, silage and beet) were administered in 3 portions (P1, P2, and P3) per day, in 2 equal feedings (F1, F2) per portion. During the experiments, the following drinking behavior aspects were determined: the number of drinkings, the length of drinking periods (sec.) and average duration of one drinking (sec.). Data was computed by ANOVA/MANOVA. Results showed that the feedings had an influence on the number of water intakes and their duration in all three portions. Between F1 and F2, very significant differences (p<0.001) were in P1 and P3 for number of drinkings and their duration, and significant differences (p<0.01)   were for average duration of one drinking. In the P2 portion, the differences between F1 and F2 were very significant (p<0.001) for all indicators
