BEHAVIOURAL INDICATORS IN THE NUTRITION-EXCRETION PROCESS OF THE HOLSTEIN-FRIESIAN CATLLE EXPLOITED AT S.C.D.A. SIMNIC

Abstract

Within their nutrition process, Holstein-Friesian cattle have an acceptable behaviour: ingestion, rumination, watering, defection and urination occur more frequently during the day than during the night, which is normal if we consider the fact that most of the food is administered during the day. In terms of duration, the nutrition process, seen from the perspective of the indicators of ingestion, rumination and watering, lasts for 730 minutes, which represents 50,59 % of the 24-hour lapse of time. The frequency and the duration of the rounds of standing up and sitting down highlight, by the results, the fact that Holstein-Friesian cattle are influenced by the stressful factors in their shelter; these stressful factors produce anxiety, perturb the rest and can consequently perturb production as well.
