E. A. Ott and R. L. Asquith

Although still available in very limited quantities, Florida 77
alfalfa offers the potential of providing a locally produced legume forage
for feeding horses. Its greatest potential would appear to be for young
animals with high protein and mineral needs. This experiment was planned
to compare locally produced Florida 77 alfalfa hay with locally produced
Alecia bermudagrass hay supplemented with two concentrates on the growth
and development of weanling horses.

Experimental

'Tenty-one Thoroughbred and Quarter Horse foals were weaned at 112
days of age and started on the experiment at 122.1 1.1 days of age. The
foals were weighed, measured and x-rayed for bone density at the start of
the experiment and assigned at random to one of four treatment groups.
The treatments were: Group A Alecia Bermudagrass hay plus 14% crude
protein (CP) concentrate, group B Alecia Bermudagrass hay plus 17% CP
concentrate, group C Florida 77 Alfalfa hay plus 14% CP concentrate and
group D Florida 77 Alfalfa hay plus 17% CP concentrate. Hay was fed at
1 lb/100 lb BW daily. Concentrates were fed to appetite for 2, 1.5 hour
feeding periods daily. Composition of the hay and concentrates fed are
shown in table 1. The foals were weighed and measured at 14-day intervals
for 112 days. The foals were re-x-rayed for bone density at the end of
the trial.
Results

Daily feed and nutrient intake for the four treatment groups are shown
in table 2. Animals receiving the high protein (HR-76) concentrate con-
sumed significantly more concentrate and total feed (P<.1) than those on
the low protein (HR-75) concentrate. No difference in hay intake was
noted. Total intake per unit of body weight (BW) appeared to be slightly
lower on the alfalfa fed foals. Energy intake was higher for the foals
consuming the high protein concentrate reflecting the greater concentrate
intake for groups C and D. Groups C and D consumed more protein than
groups A and B due to the higher protein content of the alfalfa hay. No
significant sex effects on feed or nutrient intake were detected.

Weanlings consuming the high protein concentrate (HR-76) gained more
weight (P<.05) and length (P<.1) than weanlings consuming the low protein
concentrate (table 3). Other growth parameters were not affected by the
concentrate. Hay had no effect on growth of the foals and there was no
concentrate/bay interaction. The males gained faster than the females in
this trial (P<.05).
