Abstract
In Experiment 1 sixty (60) male Ethiopian Menz sheep of
average live weight of 19.00kg (SE 1.42) maintained on
maize stover ad libitum were supplemented with either
lablab (250g) (LL); cowpea (250g) (CW); blood meal (50g)
(BM); lablab (125g)+ cowpea (125g) (LC); lablab (125g)+
blood meal (25g) (LB) or cowpea (125g)+ blood meal (25g)
(CB) for a period of 75 days. Voluntary intake, weight gain
and changes in rumen environment were studied. Sheep fed
blood meal, and blood meal in combination with forages
legume consumed significantly more stover (P<0.001) than
sheep fed the other supplements.
Sheep on blood meal and blood meal in combination with
forage legumes had significantly higher (P<0.001) weight
gains than those fed the other supplements. Treatments did
not differ significantly in the rumen degradation
parameters for organic matter and nitrogen, microbial
protein yield and rumen digestion kinetics parameters.
In Experiment 2, 36 male Ethiopian Menz sheep of average
liveweight 19.2 (SE 0.042)kg) fed maize stover were
supplemented with urea-molasses block containing one of
the following supplements: wheat bran (WB), cottonseed cake
(CC), blood meal (BM) or CC + BM (CB) over a period of 75
days. Voluntary intake and changes in the rumen environment
were measured.
Differences in the stover DM intake were not significant
but the supplement intake differed significantly (P<0.05)
among treatments. There were significant differences
(P<0.01) in the weight gains between treatments. There
were no significant differences in purine derivatives and
microbial protein yield. Rumen degradation parameters did
not differ significantly among the various urea molasses
blocks.
The use of blood meal increased stover DM intake, weight
gains and improved the rumen environment for microbial
protein synthesis. It was concluded that blood meal could
be used as supplement to poor quality roughages.
