The Nutritive Value of Silages Made from Mixtures of Pearl Millet
(Pennisetum americanum) and Lablab (Lablab purpureus) as
Feed for Yankasa Rams
A study was conducted with the field grown Pearl millet (Pennisetum
americanum) and Lablab purpureus. The aim of the trial was
to study the effect of the addition of Lablab legume in varying amount
or the composition of daily intake and utilization of millet-silage by
Yankasa sheep. Both crops were harvested separately, wilted, chopped and
then mixed in four proportions (0:100, 15:85, 30:70 and 50:50% of lablab:
millet, respectively) and ensiled. Silage treatments were found to be
similar in concentrations of Dry Matter (DM), Organic Matter (OM) and
Ether Extract (EE), while incorporation of lablab led to a small increase
in Crude Protein (CP), Crude Fibre (CF) and Nitrogen Free Extract (NFE).
All millet-lablab mixtures were adequately fermented with favourable aroma
and colour. Comparisons of the four silage treatments revealed that, silage
with 50:50 millet-lablab proportion was the most readily consumed by the
rams with a mean intake of 48.4 g kg-1 W0.75 and
lowest intake of 22.5 g kg-1 W0.75 for treatment
with 0:100 lablab-millet proportion. Digestion coefficients declined steadily
from the control (0:100% lablab-millet mixture) to 50% level legume incorporation.
This investigation showed that the best performance of Yankasa rams on
the basis of intake and digestibility was obtained from treatment with
50:50, lablab-millet mixtures.
