INTRODUCTIONDigestibility of high fiber feed depends on cellulolytic microbes. In order to maximize the degradation of fibrous feed, the growth of ruminal microbes is needed to be improved. One effort to increase the microbe population in the rumen is by manipulating the adequacy of nutrients for their growth.Microbes in the rumen require energy and protein for their growth and development. A synchronized protein-to-energy ratio indicates optimal fermentation efficiency. Cattle fed only fermented rice straw may be able to provide energy from structural carbohydrates of the rice straw. However, since fermented rice straw also contains rapidly degraded N derived from urea that used in fermentation process, feedstuffs that contain rapidly degraded carbohydrates (non-structural carbohydrates) such as cassava tuber can be used. On the other hand, to synchronize the slowly degraded carbohydrate of rice straw, slow degraded protein source feedstuffs such as cassava leaves can be added. With a good balance of energy and protein availability in the rumen, an increase of microbial population as well as increasing volatile fatty acids (VFA) production in the rumen can be expected.Cassava as a local food commodity in Indonesia is abundant throughout the year. Cassava tuber is known as a good carbohydrate source that is degraded rapidly, while the leaves contain quite high crude protein (CP) which is ranged 20 - 36% (Askar, 1996). The rapidly degraded carbohydrates in cassava tuber and slowly degraded CP in cassava leaves are a good combination as additional feed for cattle fed fermented rice straw. Based on these, a research that focused on improving the in vitro digestibility of fermented rice straw basal feed by supplemented with cassava tubers and leaves was established.
MATERIALS AND METHODSThis research was conducted at the Laboratory of Feed Technology, Department of Nutrition and Feed Science, Faculty of Animal Science, Universitas Gadjah Mada, Yogyakarta, Indonesia. The experimental design used in the study was a 2×2 factorial experimental design, with 2 levels of cassava tuber (without or with 5% cassava tuber) and 2 levels of cassava leaves (without or with 5% cassava leaves). Fresh cassava (Manihot utilisima) tuber and leaves were collected from Gunungkidul area, while fresh rice straw was gathered from Sleman area, Yogyakarta. Fresh cassava tuber and leaves were dried under direct sunlight, and then ground using hammer mill with 1 mm screen. The probiotic used for rice straw fermentation was Starbio® at a dose of 0.3% of dry matter (DM) of rice straw with probiotic-to- urea ratio was 1: 2 (1 g probiotic + 2 g urea/kg DM). After mixed with probiotic and urea mixture, rice straw was stored in the room temperature for 3 weeks.The chemical compositions of samples were analyzed by proximate analysis according to (AOAC, 2005). The chemical compositions of fermented rice straw, cassava tuber and leaves are presented in Table 1. The in vitro digestibility analysis was carried out using two-stage in vitro method (Tilley and Terry, 1963). The data were analyzed by one-way analysis of variance (ANOVA) using SPSS ver. 22 (IBM, USA). Comparisons of means for treatments were done by contrast test with Duncan’s new multiple range tests (Gomez and Gomez, 1984) when the effects of treatments (P ≤ 0.05) were detected.
RESULTS AND DISCUSSSIONThe results of supplementing cassava leaves and tuber in fermented rice straw on in vitro digestibility of DM, organic matter (OM), and CP are presented in Table 2.Dry matter and OM digestibilities (DMD and OMD) of fermented rice straw were increased (P <0.05) due to cassava tubers supplementation, while no significant effect was detected on CP digestibility (Table 2). Cassava contains non-structural (62.5%) and structural carbohydrates, which includes 2.69% cellulose, 0.36% hemicellulose, and 0.02% lignin (Arnata, 2009). Therefore, by adding cassava tuber in the diet would increase the soluble carbohydrates availability in feed. Since soluble carbohydrates is rapidly fermented in rumen, the volatile

fatty acids (VFA) and adenosine triphosphate (ATP) production from this fermentation may increase, thus more energy is available for microbial growth which lead to greater microbes population in the rumen. Furthermore, the increasing soluble carbohydrates from cassava tuber matched with rapidly degraded N of urea contained in the fermented rice straw, thus the rumen microbes population might be increased significantly. With greater microbe population in the rumen, feed can be degraded more efficient which ended with greater DMD and OMD.Compared with controls, the digestibilities of DM, OM, and CP of fermented rice straw were increased (P <0.05) due to cassava leaves supplementation (Table 2). The digestibility improvement of fermented rice straw due to cassava leaves supplementation were caused by increasing amount of protein available in the feed. In this study, CP content of dried cassava leaves was 30.6%, which was greater than the other reports (Inthapanya et al., 2012 Kiyothong and Wanapat, 2003). Furthermore, the cassava leaves supplementation (as slow degraded protein source) also matched with structural carbohydrates of fermented rice straw, which also leads to increasing population of rumen microbes and then resulted in greater in vitro digestibility of the diet.A positive interactions on DM, OM, and CP digestibilities due to cassava tuber and leaves supplementation were noticed (P<0.05 Table 2) with the best effects was shown in the T1× L1 (34.0, 45.2, and 34.5%, respectively). These results was achieved due to the soluble carbohydrates of cassava tuber matched with the urea from fermented rice straw while the slowly degraded protein of cassava leaves matched with the structural carbohydrate of fermented rice straw. These combinations created a good balance between energy and protein availability in the rumen for microorganisms growth. Previous researcher reported that adding rapidly degraded carbohydrates and protein feedstuffs improved growth of rumen microbes (Kurniawati, 2007).
CONCLUSIONSupplementing cassava tubers and leaves on fermented rice straw in this study showed positive effects on the in vitro digestibility of fermented rice straw with the best combination was at 5% cassava tuber and 5% cassava leaves.
