COMBINATION OF SOYBEAN MEAL AND Hibiscus tiliaceus LEAF IN THE GOAT DIET: EFFECT ON SOME PARAMETERS OF CARBOHYDRATE METABOLISM

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengkaji efek kombinasi dari daun waru dengan protein bungkil kedelai dalam pakan pada beberapa parameter metabolisme karbohidrat. Materi yang digunakan adalah 16 ekor kambing Peranakan Ettawah berumur 7 bulan dengan bobot badan 16 kg. Perlakuan terdiri dari T0 = Pakan komplit (saponin dan waru 0,90%, PK 8,69%, TDN 62,11%), T1 = T0 + 3% protein bungkil kedelai, T2= T0 + 6% protein bungkil kedelai, dan T3= T0 + 9% protein bungkil kedelai. Penelitian ini dilakukan dengan menggunakan rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa perlakuan ransum tidak menunjukkan pengaruh nyata (P>0,05) terhadap konsumsi bahan kering, karbohidrat, energi, konsentrasi butirat dan valerat rumen. Konsumsi protein, kecernaan pakan, konsentrasi asetat dan propionat rumen, estimasi CH 4 , rasio non-glukogenik meningkat (P<0,05) akibat perlakuan. Suplementasi protein dalam daun waru yang terkandung dalam pakan disarankan harus diseimbangkan dengan tingkat energi.

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.

The Utilization of Coconut Coir as Supplementary Feed for Beef Cattle Production

“…Treatments D1, D2 and D4 were not significantly different but higher than the D3 feed. These results are consistent with the reports of Amaryanti et al (2015) that microbial protein production was not significantly different (P > 0.05) in the use of a combination of soybean meal and Hibiscus tiliaceus leaves in goat feed.…”

“…As shown in Figure 1, the efficiency of hexose utilization showed is not much different. These results are in line with Amaryanti et al (2015) that found the efficiency of hexose utilization insignificantly different in using the combination of soybean meal and hibiscus leaves in goat feed. 4, microbial protein production showed significant differences between the four treatments.…”
