Abstract:

Four groups of Israeli-Friesian male cattle were fattened in pens with concrete slatted floors from an initial live weight of 138 kg up to 450 kg at slaughter. Floor space per animal differed between groups, of which two were fed ad lib. and two restricted. One group had an adjoining uncovered yard. Both DM intake and daily gain different significantly from the 150th day to slaughter. The differences were directly related to floor space allowance per animal. Animals of the smaller space allowance had a significantly higher dressing percentage, but they were not significantly fatter. © 1979.
