levels (8.3 mg/100 ml vs. 11.0 mg/100 ml) than the younger<br />

group. Management system had no effect on feed cost/kg<br />

gain, while UMMB supplementation increased the cost<br />

per kilogram weight gain. Cost/kg gain was higher in 12 to<br />

24 months age group than the 6-14 months age group.<br />

A grazing trial was conducted during the wet season to<br />

determine the performance of caracows subjected to the<br />

following treatments; grazing on Themeda pasture (T 1 ),<br />

grazing + rice bran supplementation (T 2 ), grazing + rice<br />

bran + urea molasses mineral block (UMMB)<br />

supplementation (T 3 ), grazing damaged + palay<br />

supplementation (T 4 ), and grazing + damaged palay +<br />

UMMB supplementation (T 5 ). The caracows on T 1 had a<br />

negative weight gain during the feeding trial. However,<br />

gain of animals on T 2 , T 4 , T 3 and T 5 were significantly higher<br />

by 14, 15, 21 and 23 percent, respectively, than those in<br />

T 1 . The better liveweight gains of grazing caracows fed<br />

with supplements could be attributed to higher dry matter,<br />

N, and fermentable carbohydrate intake.<br />

Sixteen mature caracows were drawn from Phase I<br />

experiments and used in the dry season feeding experiment<br />

to determine their performance when fed with the following<br />

dietary treatments: T 1 - grazing; T 2 – grazing + urea molasses<br />

mineral block (UMMB); T 3 – grazing + UMMB + rice bran<br />

and T 4 – grazing + urea molasses sprayed rice straw.<br />

Results showed that animals in T 2 , T 3 and T 4 had a<br />

significantly higher growth rates than animals in T 1 during<br />

the peak of the dry season (April). Higher dry matter<br />

intake (DMI) and blood urea-nitrogen were also observed<br />

from animals fed with supplements confirming the previous<br />

observation that supplementary urea either as lick or spray<br />

along with molasses can increase the amount of recycled<br />

nitrogen and improve the efficiency of feed utilization.<br />
