RESEARCHES REGARDING CONSUMPTION SPEED OF FORAGES IN MULTIPAROUS ROMANIAN BLACK AND WHITE COWS DURING COLD SEASON. 1. ADMINISTRATION OF RATION IN TWO PORTIONS
Keywords:
consumption speed, multiparous cows, Romanian Black and WhiteAbstract
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.
