Experiment 2: Thirty-six Charolais Friesian and 18
Friesian spring-born steers which had just completed their
second grazing season (19 months of age) were housed for
their second winter and blocked on weight, within breed, to
three treatment groups. Within finishing treatment and
breed type, the animals were assigned at random to three
pens of six animals each (4 Charolais Friesians + 2 Friesians
per pen). These were considered replicates for the
purposes of feed intake measurements. All animals were
offered grass silage ad libitum for 3 weeks prior to commencement
of the study (day 0). The control treatment
was grass silage ad libitum + a flat rate of 6 kg concentrates
