Abstract


The aim of this research was to describe some aspects regarding the intake behavior, during cold-season in Romanian Black and White cows. Researches were carried out on 10 multiparous cows (in their first 100 days of lactation), housed in a tied stanchion barn 24 hours per day. During current study the consumption speed for varied forages type, specific during cold season (corn silage, pasture hay, concentrates and brewer’s yeast) was pursued. Forages were offered in two equal portions each day. Portions were provided to cows in different orders, corn silage – pasture hay (variant A) or pasture hay – corn silage (variant B). Intake rate (consumption speed) was calculated in minutes per kilograms of raw feed. Average consumption speed values were calculated as follows: concentrates 3.32 min/kg, pasture hay 22.27 min/kg, corn silage 4.41 min/kg and brewer’s yeast an average of 2.10 min/kg.
