“…The dietary starch degradation in rumen was increased in defaunated sheep (Mendoza et al, 1993). There is a contrary between this experimental result and others (Kiran and Mutsvangwa, 2010;Grummer et al, 1983;Han et al, 1999;Mendoza et al, 1993), because before and after feeding ruminal acetate concentration was also increased by the protein supplementation ( Table 2). As the part of this study, the rumen digestible organic matter was unaffected by protein supplementation (Akhsan et al, 2015).…”

“…Furthermore, the growth of rumen bacteria were not increased by the dietary protein supplementation combined with Hibiscus tiliaceus leaf, because the amount of estimated microbial nitrogen synthesis was unaffected by the treatments (Akhsan et al, 2015). On other hand, ruminal degradability of dietary neutral detergent fiber, acid detergent fiber and hemicellulose were increased by the defaunation in sheep (Han et al, 1999). Likewise, Mendoza et al, (1993) reported that amylolitic activity of rumen bacteria was higher in defaunated than that of faunated conditions.…”

“…Kiran and Mutsvangwa (2010) (Grummer et al, 1983). Ruminal acetate and butyrate concentrations were decreased but propionate concentration was increased in defaunated sheep fed on high fiber diet (Han et al, 1999). The dietary starch degradation in rumen was increased in defaunated sheep (Mendoza et al, 1993).…”

“…The rumen microbes play an important role in feed digestion but defaunation generally has negative effect on ruminal fiber degradation, although removing protozoa from rumen reduces methanogenesis positively (Mosoni et al, 2011). In sheep fed on fiber rich diet, partial defaunation increases positive effect of rumen protozoa and decreases negative effect of protozoa (Han et al, 1999). Protozoa rumen reduces starch digestion in sheep (Mendoza et al, 1993).…”

“…The defaunation may affect on the growth of rumen bacteria negatively, because ruminal ammonia concentration was decreased (Kiran and Mutsvangwa, 2010) and ruminal volatile fatty acids concentration was increased (Han et al, 1999) in defaunated ruminants. These facts in turn may decrease capability in the ruminal fermentability for dietary fiber.…”

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. Kata Kunci : defaunasi, suplementasi protein, pemanfaatan karbohidrat, kambing ABSTRACTThe 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.

Effect of an anti-methanogenic supplement on enteric methane emission, fermentation, and whole rumen metagenome in sheep

et al. 2022

A study was conducted to investigate the impact of an anti-methanogenic product supplementation on enteric methane emissions, whole rumen metagenome and ruminal fermentation in sheep. Twelve adult male sheep were randomly divided into two groups of six animals each. Animals were fed ad libitum on a total mixed ration either without (CON) or with an anti-methanogenic supplement (Harit Dhara-HD). The anti-methanogenic supplement contained 22.1% tannic acid in a 3: 1 ratio of condensed and hydrolysable tannins. The supplementation of product revealed a significant reduction in daily enteric methane emission (21.9 vs. 17.2 g/d) and methane yield (23.2 vs. 18.2) without affecting the nutrient intake and digestibility. However, the propionate concentration in the HD treatment group was significantly higher than in the CON group. On the contrary, the ammonia nitrogen concentration was lower. The anti-methanogenic supplement significantly decreased the ruminal protozoa in the HD treatment group. Whole rumen metagenome analysis revealed that the core bacterial (Bacteroidetes and Firmicutes) and archaeal communities (Methanobrevibacter and Methanosarcina) were comparable between the CON and HD treatment groups. However, the supplementation of anti-methanogenic product led to a considerable reduction in the abundance of Proteobacteria, whereas the abundance of Lentisphaerae was greater. The supplementation significantly decreased the abundance of Methanocaldococcus, Methanococcoides, Methanocella, and Methanoregula methanogens. A total of 36 KO related to methanogenesis were identified in this study. The activities of formate dehydrogenase (EC 1.8.98.6) and tetrahydromethanopterin S-methyltransferase (EC 2.1.1.86) were significantly lowered by the anti-methanogenic product supplementation in sheep. In conclusion, the anti-methanogenic supplement has the potential to decrease enteric methane emission (~22%) at the recommended level (5% of DM) of supplementation. The contribution of minor methanogens vulnerable to supplementation to rumen methanogenesis is not known; hence, the culturing of these archaea should be taken on priority for determining the impact on overall rumen methanogenesis.
