Nutritional Qualities of Cocoa Pod Husk Treated with Bioconversion and or Provision of Nitrogen Sources in the Rumen

The objective of this study was to investigate the effects of bioconversion using Phanerochaete chrysosporium and Pleurotus ostreatus and or inclusion of Moringa oleifera leaves and urea in the rumen on cocoa pod husk digestibility and fermentation in the rumen. There were 4 treatments tested: (1) 100% untreated cocoa pod husk (UCPH), (2) 55% UCPH + 43.7% M. oleifera + 1.30% urea (UCPHMU), (3) 100% bioconverted cocoa pod husk (BCPH), and (4) 55% BCPH + 44.5 M. oleifera + 0.5% urea (BCPHMU). Each of the treatments was replicated three times. Variables observed were dry matter and organic matter digestibilities and degradabilities, rumen VFA and ammonia concentrations, gas production, and calculated microbial biomass yields. Results indicated that the treatment increased dry matter (P<0.001) and organic matter (P<0.01) digestibility, with the highest for the BCPHMU and the lowest for the UCPH. The treatments also increased dry matter and organic matter degradability in the rumen (P<0.001), with the highest for the BCPHMU, followed by the UCPHMU, and then by the BCPH and the lowest was UCPH. The treatment affected rumen ammonia concentration (P=0.01), the highest value was found for the BCPHMU followed with UCPHMU and BCPH. Microbial biomass synthesis was affected (P<0.001) by the treatment and it was always higher when nitrogen was provided (UCPHMU and BCPHMU). Total VFA concentration or total gas production was higher for BCPHMU compared to other treatments. It can be concluded that nutritional quality of cocoa pod husk can be improved by either bioconversion with P. chrysosporium and P. ostreatus or inclusion of M. oleifera and urea in the rumen, but the best improvement can be obtained by the combination of bioconversion and provision of the nitrogen sources in the rumen

OPTIMASI VOLUME PELARUT DAN WAKTU MASERASI PENGAMBILAN FLAVONOID DAUN BELIMBING WULUH

Bilimbi is one of the plants that contains flavonoids and it can be found in Indonesia, however its utilization is not optimal yet. Flavanoids are known as one of the largest natural phenols which has functions not only as an antioxidant but also can protect the cell structure, improve the effectiveness of vitamin C, antiinflammatory, preventing bone loss, antidiarrheal, antidiabetic and antibiotics. Some previous research is focused on testing the effectiveness of flavonoids as traditional medicine, but there is no research evaluating the optimal conditions of flavonoids extraction from bilimbi’s leaves. This research aims to determine the optimal conditions which include the volume of solvent and maceration time, in order to obtain the most optimal of flavonoids extracted and are expected can improve its effectiveness as materials for traditional medicine in the future. The research begin with the preparation of materials. Then, 10 grams of bilimbi’s leaves were macerated using ethanol 96% by volume solvent and maceration time varied. Before the maceration time is calculated, stirring with a mercury stirrer speed of 200 rpm for 1 hour. Liquid extract of maceration is filtered by using a buchner funnel, then concentrated by using rotary evaporator. Condensed extract was analyzed quantitatively by using UV-Vis spectrophotometer. Optimal conditions of this research was obtained when using volume of solvent 250 mL and macerated for 48 hours which 72.31 mg of flavonoids extracted as its result

The Effect of Protecting Lysine and Methionine with Condensed Tannin Added Into Total Mixed Ration on Efficiency of Microbial Protein Synthesis by Using an in Vitro Gas Production Approach

An in vitro study investigating the effects of adding CT-protected Lysine (Lys) and Methionine (Met) on gas production and efficiency of microbial protein synthesis (EMPS) of total mixed ration (TMR) was conducted at Animal Nutrition Laboratory.  TMR were composed of concentrate and maize stover at 50:50 ratios in DM basis. The experiment used 4x4 factorial randomized design and 3 replications. The first factor  was level of Lys and Met (3 g Lys- 1 g Met; 5 g Lys- 1.67 g Met; 7 g Lys- 2.33 g Met; 9 g Lys- 3 g Met) and  the second factor  was level or percentage of  CT  (0%, 6%, 8% and 10%) of Lys and Met. Parameters measured were cumulative gas production recorded at 0, 2, 4, 8, 12, 16, 24, 36 and 48 h, DMD and OMD of residues, concentrations of NH3 and VFAs, and EMPS. The results showed that there was interaction effect between levels of Lys-Met and CT on cumulative gas production and b value, with treatment A1B3 (3g Lys + 1g Met) + 8% CT) being the lowest (106.2 ml 121.9 ml) and A4B1 (9g Lys + 3g Met) being the highest (121.9 ml and 136.8 ml). Increasing level of  Lys-Met alone significantly increased cumulative gas production, DMD, and ammonia-N, but did not increase c value, OMD , concentrations of acetic, propionic and butyric acids, total VFA, ratio of C2/C3, and EMPS. Increasing level of CT reduced cumulative gas production; b value, ammonia-N, C2, C3, C4, and total VFA, with 0% CT and 10% CT being associated with the highest and the lowest value of those parameters. The highest value of EMPS was found on treatment A1B4 (3g Lys + 1g Met+10% CT; 50.3 g N/kg DOM). It can be concluded that CT is able to protect Lys-Met from being fermented in the rumen, hence improving EMPS value. Keywords: lysine, methionine, CT, in vitro gas productio

Botanical Composition and Quality of Ruminant Feed Resources in the Dry Land Farming Areas in Yogyakarta, Indonesia

This study aims to determine the botanical composition and quality of ruminant feed resources in dry land farming areas. The research toke place in  Kemejing village, Semin subdistrict, Gunugkidul district, Yogyakarta province, Indonesia. Data obtained in a participatory rural appraisal method of 17 samples of farmers which are determined by purposive sampling. Data taken within two  seasons namely dry season and the wet season each for 4 x 10 days and 3 x 10 days are respectively along with agricultural harvest crops. All the data obtained are reported descriptively. The results showed that the type of feed given to cattle is very varied. There are 35 species in the dry season and 15 species in the wet season. There is no concentrates were used as feed for 2 seasons. Rice straw is the most dominant type of feed used as feedstaff seen from the frequency of services and the amount consumed both in the dry and wet season, followed by elephant grass, corn straw, native grass and peanut straw. Ration composition was dominated by two types of feed rations by both dry and wet season with a variety of types 1-6 in the dray season and 1-4 type on the wet  season. The chemical composition is not much different for each type of feed between seasons, whereas the greatest difference between the different types of feed. The conclusion, farmers provided feed to the cattle have not been based on the nutrient requirements for production, but rather the number of quantity (stuffed animals). And to survive in difficult circumstances widely used feed forage feed from other plants. Key words: feed resources, botanical composition, ruminant, dry land, forage, cattl

Feeding strategies for improving ruminant productivity in the post-COVID 19 pandemic era particularly for small holders

COVID-19 has highlighted the need for robust cattle supply chains using local feed resources. Higher Income Over Food Costs (IOFC) are usually achieved when live weight gains are high and the cost of the ingredients are low. There is a need to formulate rations with high metabolisable energy (ME) and crude protein (CP) to achieve the high live weight gain. Rations can be formulated locally by farmer co-operatives, entrepreneurs and local commercial enterprises to take advantage of cheaper prices for local ingredients. To do this, rations need to be altered quickly to take advantage of local fluctuations in prices and availability of ingredients. A recent ACIAR funded project has developed a least cost ration (ACIAR LCR) system to formulate rations to meet minimum ME and CP contents for beef cattle using locally available ingredients. The use of cassava and its various products in combination with protein sources, such as tree legumes and high protein by-products, have markedly improved IOFC
