THE PHILIPPINE WATER BUFFALO

The digestibility of rice straw (RS) and rice straw molasses
silage (RSMS) were determined using cattle and carabaos.
Results show that cattle were as efficient as carabaos in
utilizing nutrients from RS. The digestible protein (DP) of
rice straw was 1.15 ± 0.51 percent for cattle and 1.11 ±
0.10 percent for carabaos. The total digestible nutrients
(TDN) were similar: 48.62 ± 1.51 and 49.04 ± 1.27 percent
for cattle and carabaos, respectively. The corresponding
digestible energy (DE) for RS in both species were likewise
similar at 1972 ± 65 and 1963 ± 44 kilocalories per kg of
dry matter. Although the DP of RSMS for both species
was comparable to RS, the TDN for cattle declined to
about 33 percent and for carabaos to 36 percent. The DE
of RSMS also dropped to 151 and 1669 kcal dry matter for
cattle and carabaos respectively. The result suggests that
RSMS has lower feeding value compared to RS.

The digestible nutrients of high moisture corn (HMC) fed
as whole grain, ground before feeding and ground before
ensiling were determined using carabaos and Holstein x
Red Sindhi steers. There were no significant differences in
the digestible nutrients of the three forms of HMC for cattle.
In general, carabaos were better than cattle in digesting the
3 forms of HMC. Except for significantly higher nitrogen
retention in carabaos fed on HMC ground before feeding,
both species responded with almost the same amount of

nitrogen retained. In a 2x2x3 CRD factorial experiment, 12
male carabaos and 12 male cattle were fattened for 5 months
to compare the feedlot responses to corn with different moisture
levels and hormone implantation. Rice straw molasses
silage (RSMS) was given ad libitum. The total dry matter
(DM) intakes of cattle fed HMC and low moisture corn
(LMC) were not significantly different. Diethylstilbestrol (DES)
implanted animals consumed significantly higher DM than
the controls. Among carabaos
DES implanted animals and the controls did not differ
significantly in their DM intake. Animals given LMC consume
significantly more DM than those given HMC. Cattle
significantly consumed more DM than carabaos. The average
daily gain (ADG) of cattle fed LMC was significantly higher
than those given HMC. However, when RSMS
consumption was corrected to a constant level, the difference
in gains between HMC and LMC groups was not significant.
There were no significant differences in the ADG of the two
species, 0.75 kg for cattle and 0.70 kg for carabaos. Feed
efficiency was not significantly affected by either moisture
level of corn or DES implantation in both cattle and carabaos.
No significant difference was observed in feed efficiency
between the two species. The dressing percentages of
cattle and carabaos were not affected by either moisture
level of corn or DES implantation. Cattle gave significantly
