Abstract |
This study was carried out to determine the effect of a bacterial
inoculant, urea and molasses on chemical composition and nutritive value
of ensiled pomegranate seed pulp (PSP) and pomegranate
peel pulp (PP). The treatments were
100% PSP (T1), 100% PP (T2), 75% PSP
and 25% PP (T3), 25% PSP and75% PP
(T4), 50% PSP and 50% PP (T5), 50%
PSP and 50%
PP with 5% urea (T6), 50% PSP and 50%
PP with 5% molasses (T7), 50% PSP and
50% PP with bacterial inoculant
(T8), 50% PSP, 50% PP with 5% urea and 5% molasses and
50% PSP (T9), 50% PP with 5% urea and 5%
molasses and bacterial inoculant (T10). The bacterial inoculant (Lactobacillus
plantarum) was applied at the recommended level of 1×105
CFU/g. The materials were ensiled for 30 days in plastic polyethylene
bags. At the end of the ensiling period, all silages were subjected to
chemical analysis and in vitro gas production. After
fermentation, pH values in silage treated with inoculant decreased below
4.0 and the addition of urea
increased pH to 5.47 and had
highest crude protein (CP) content (P<0.05).
Ensiling PP was superior to PSP with respect to higher (P<0.05)
gas production, organic matter digestibility (OMD), digestible organic
matter in dry matter (DOMD) and metabolizable energy (ME) values and T2
and T9 had higher (P<0.05) OMD,
DOMD and ME values. Gas production was higher (P<0.05) for T2 but was
intermediate for T9. Also, the results indicated that the application of
urea and molasses resulted in silages with higher OMD, DOMD and ME
values. In conclusion, ensiling pomegranate peel pulp with or without
urea and molasses can provide a valuable feedstuff for ruminants.
