Research on Rumination Time According to Administration Order of Forages in Romanian Black and White 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 measure the main aspects that characterized the rumination behavior of the cows in 24 hours that were divided into 3 day periods: 07:00-14:00 (I1), 14:00-2:001 (I2), 21:00-07:00 (I3).  During the experiments, the following rumination behavior aspects were determined: the number of ruminating periods, their total duration (min.), number of  chewing, the length of one ruminating period (min.) and average number of chewing per period according to administration order of forages: fibrous-succulents (O1)   and succulents-fibrous (O2),  in cows housed in tie stalls. Data was computed by ANOVA/MANOVA. In fibrous – succulent order (O1), results showed that the differences between intervals I1-I3 and I2-I3 were statistically very significant (p< 0.001) for most measured parameters. In succulent – fibrous order (O2), significant differences was between intervals I1-I3, I2-I3 and between intervals I1-I2 for some parameters.
