COMBINATION OF SOYBEAN MEAL AND Hibiscus tiliaceus LEAF IN THE GOAT DIET: EFFECT ON SOME PARAMETERS OF CARBOHYDRATE METABOLISM
ABSTRACT: The purpose of this
study was to clarify effect of the combination of waru leaf (Hibiscus
tiliaceus) sapponin with soybean meal protein in the goat diet on some
parameters of carbohydrate metabolism. The study used 16 Ettawah cross bred
male goats with body weight average of 16 kg and aged at 7 months. The dietary
treatments were: T0 = total mixed ration (0.09% of Hibiscus tiliaceus leaf
sapponin, 8.69 % of CP, 62.11% of TDN), T1 = T0 + 3% soybean meal protein, T2 =
T0 + 6% soybean meal protein, and T3 = T0 + 9% soybean meal protein. The
treatments were allotted in a completely randomized design, with 4 treatments
and 4 replicates of each. The results showed that dietary treatments did not
effect significantly (P>0.05) on intakes of dry matter, carbohydrate,
energy, ruminal butirat and valerat concentrations. Crude protein intake, feed
digestibility, ruminal acetate and propionate concentrations, ratio of
non-glucogenic to glucogenic VFAs, and estimated methane production were
increased (P<0.05) by dietary experiments. The protein supplementation in a
Hibiscus tiliaceus leaf contained diet should be balanced with the energy
level.
