Bark, especially from Acacia mangium is a by-product from wood processing industries that commonly found in Indonesiaand in big amount will cause environmental problems. One of the alternatives to utilize bark is for animal feed. The aims of this experiment are to improve the nutritive value of bark by alkali treatments (urea and sodium hydroxide) and to determine the level of substitution of elephant grass by bark. The experiment consisted of 3 in vitro studies and 1 in sacco study. In vitro studies consisted of 1) the use of urea or NaOH by wetting and incubation-method, 2) the use of different concentration of Na OH (0-4%) by soaking method, 3) determination of substitution level of elephant grass by treated bark. In sacco study was conducted at 0, 6, 12, 24, 48 and 72 hours of incubation to compare the degradation of treated bark to elephant grass. The results show that urea treatment did not improve DM or OM digestibilities of bark. Soaking bark in 4% NaOH solution was more effective than wetting and incubation-method in improving in vitro digestibility. (49.26% vs19.56% for soaking and dry-method, respectively). In sacco studyl shows that treated bark had a very high solubility at 0 hour incubation but the degradation at 72 hours incubation was not significantly different from that of 0 hour incubation. The gas produced at in vitro study of treated bark was very low indicated that there was no degradation of bark at all. The level of substitution of elephant grass by treated bark up to 30% gave a non-significant digestibility value to that of 100% elephant grass. In conclusion, bark after tannin-extraction was a better feedstuff for animal feed. The soaking method in 4% NaOH solution improved the digestibility of bark significantly and the level of substitution of elephant grass by treated bark was 30%.

Cultures of fungi, especially Aspergillus oryzae, have been of interest to animal nutritionists to increase feed efficiency. Many experiments have been done and showed positive results on rumen fermentation and productivity of ruminants. This paper reports the results of an in vivo study on feeding Aspergillus oryzae, fermentation culture (AOFC) to growing sheep. âOnggokâ (tapioca processing waste) was used as media for AO cultivation after being enriched with a mineral mixture. Commercial concentrate (GT-03) was fed to 15 growing sheep supplemented with 0% (C0), 5% (C1), and 10% (C2) AOFC (w/w). Chopped fresh King grass was used as a basal diet. The 3 treatments were randomly allotted to the sheep according to randomized block design with 5 replications. The study was carried out for 14 weeks. Digestion trial was conducted in the last 10 days of experiment. All feed and fecal samples were analyzed for nutrients. Rumen fluid was sampled at the mid experimental period. Analyses were done on rumen pH, ammonia content, (VFA) volatile fatly acids concentration, and also total digestive tract digestibility of dry and organic matter, crude protein, and total fiber (NDF). Differences in treatment means were analyzed by Duncanâs MRT. Feeding AOFC resulted in increased (P<0.05) digestibility of crude protein from 59.6% in control sheep to 65.5% in sheep fed concentrate with 10% AOFC supplementation. The same pattern also occurred for NDF, but no effect was found on dry and organic matter. Higher fiber digestibility with AOFC supplementation was in line with an increase (P<0.05) in cellulolytic bacteria population in the rumen. VFA produced also increased (P<0.05), as well as individual acids content, primarily acetate and propionate. No differences (P<0.05) were detected in rumen pH and ammonia content. It appears that AOFC is more suitable for the purpose of meat production. Â Key words: A. oryzae, sheep, digestibility, rumen, in vivo

Ruminal bypass proteinâ is one of the strategies to increase the amount of protein, which enters abomasum and hence, increases ruminant productivity. One of the strategies to obtain âruminal bypass proteinâ is by complexing tannin or formaldehyde with protein. Two experiments were conducted. The first experiment aimed to obtain the optimum level of added tannins to decrease the dry matter digestibility of protein sources. Tannins were isolated from Calliandra calothyrsus leaves. Tannins were added at the level of 0, 10, 20, 30, 40 and 50 mg to each in vitro tube containing 0.5 g of protein source (gliricidia leaves, soybean meal or casein) and the tubes were incubated for 48 hours. The result showed that the optimum level of tannin was 60 mg/g of gliricidia leaves or casein and 80 mg/g of soybean meal. The second experiment aimed to compare the ability of tannin to formaldehyde to form complex with protein. One set of tubes containing tannin-protein or formaldehyde-protein complex was incubated with rumen liquor for 48 h and another set was incubated with rumen liquor (48h) and followed by pepsin-HCl for 24 h (total incubation time: 72 h). After incubation at 48 h or 72 h, the dry matter or protein digestibility of tannin-protein complex was much higher than those of formaldehyde-protein complex. The amount of ruminal bypass protein was almost similar between the two agents to complex gliricidia leaves (34.4 and 32.1 g/100g for tannin-gliricidia and formaldehyde-gliricidia, respectively). Tannin-soybean meal interaction produced 27.9 g/100 g of âruminal bypass proteinâ, which was half of that from reaction between formaldehyde and soybean meal (54.1 g/100 g). Tannin-casein complex was easily broken down in the rumen so that âruminal bypass proteinâ from this complex was very small. It can be concluded that the ability of tannin to form âruminal bypass proteinâ depends on the type of protein source but is the same with the ability of formaldehyde to bind forage protein (Gliricidia sepium). Further feeding evaluation of these tannin-protein complexes is warranted. Â Â Key Words: Ruminal Bypass protein, Calliandra calothyrsus, Tannin, Formaldehyde

Utilization of jatropha seed meal as a feed ingredient is limited by the presence of several anti nutritive and toxic compounds in the seed meal. The aim of this research is to evaluate feeding of jatropha seed meal detoxified using fermentation by two fungi and rumen microbes (as biological detoxification) and using a combination of chemical and physical treatments on broiler performance. One hundred seventy five chicks (7 days old) were used and were divided into 5 treatments in 7 replications and each replication in one cage consisted of 5 chicks. R1 was control feed (K) without jatropha seed meal., 2) R2 was feed with 4% of Jatropha seed meal fermented by Neurosphora sitophila (FNS), R3 was feed with 4% of Jatropha seed meal fermented by Aspergillus oryzae (FAS), R4 was feed with 4% of Jatropha seed meal fermented by rumen microbes and R5 with 4% of Jatropha seed meal treated by autoclaved, refluxed by hexane and soaked in methanol (OEHM). Treated feed was given for 14 days at the end of the feeding treatment, two chickens from each replication were slaughtered and organ weights were recorded.Â Body weight of chicken and feed conversion ratio were calculated. The rest of the chicken was fed commercial feed for the next 7 days (recovery periode).Â Chicken mortality was almost 0% but 1 chicken from FAS treatment died at the recovery period. Feed consumption was lower at fermented jatropha seed meal than control (K) or OEHM, resulted in lower body weight of chicken. The abdomen fat weight and organ weights especially pancreas or spleen resulted from treatment with jatropha were much lower than that of K. In the recovery period, body weight of chicken in the OEHM treatment was almost similar from that of control chicken. In conclusion, biological detoxification on BBJ was able to reduce chicken mortality but could not improve the daily gain higher than control treatment. The best method to detoxify jatropha seed meal was the combination of physical and chemical treatment (using autoclave, followed by hexane and methanol extractions).

Tannin can be found in many tropical plants and the presence of tannin may reduce the nutritional value of feed. However, it can give beneficial effect as it protects the protein from its excessive degradation in the rumen. Tofu waste is abundant in a country, including Indonesia, where tofu is produced widely. A feeding trial on sheep to study the effect of tannin on microbial protein synthesis and condition of rumen fermentation, digestibility and N retention of feed containing tofu waste was conducted. Fifteen sheep were allocated to one of 3 treatments, i.e: 1) control treatment, feed without tannin, 2) feed + tannin treatment and 3) feed + tannin + polyethylene glycol (PEG) treatment. The sheep was placed in the individual metabolism cage. They were fed with treatment feed for 14 days and then, the following 7 days, faeces and urine were collected. At the end of the treatment, rumen fluid was taken from each sheep before and after feeding. Rumen parameter (pH, ammonia, SCFA, protozoa) and microbial protein synthesis, digestibility, nitrogen retention were observed. Results showed that inclusion of 4% tannin in the feed depressed ammonia production in the rumen of sheep before and 3 hours after morning feeding. Total SCFA and individual SCFA were not different among treatments. Tannin did not affect daily feed intake. Tannin lowered the dry matter, organic matter and protein digestibilities but it significantly reduced ADF digestibility (P < 0.05) and tended to reduce NDF digestibility (P < 0.1). However, tannin increased the microbial protein synthesis. PEG addition was expected to bind tannin and alleviate the negative effect of tannin.

One of energy sources for feedingÂ dairy cow is fat or oil, however, inclusion of fat or fatty acid at high level (>5% in the diet) may cause negative effect on rumen fermentation. Fat or fatty acid, therefore should be protected from its degradation in the rumen. The aim of this experiment was to evaluate protected product of palm oil fatty acid (Calcium fatty acid) made in the institute as feed supplement given on top of the ration. The first experiment was in vitro experiment using rumen liquor. Feed without and with Calcium fatty acid (Ca-FA) was incubated in buffer-rumen liquor and pH, total gas, ammonia and in vitro digetibility were measured. The second experiment was feeding trial with two treatments using 12 FH dairy cow divided into 2 groups with diet containing supplemntation 300 g of Ca-FA and other group is control treatment without supplementation. The feed was total mixed ration, comprises of elephant grass, ground corn, soybean meal, wheat pollard and coconut meal with protein content 15.1% and Net Energy for Lactation 1.53 Mcal/kg.. Feed was given to cow one month before parturition until 120 days of lactation period. Milk production was recorded daily. Faeces collection was done at the end of the experiments for 1 week to calculate total tract digestibility. The result of the in vitro experiment showed that no negative effect on in vitro rumen fermentation except higher digestibility (DMD Ca-FA addition vs control were 58.52% vs 53.99%) occurred due to addition of Ca-FA. The addition of Ca-FA increased milk production (11.41 vs 10.74 litre/day), but no effect on intake, total tract digestibility and milk quality, higher body weight of cow than control cow showing the benefit of using Ca-FA in the diet of dairy cow. In conclusion supplementation of Ca-FA at 300 g would be beneficial to increase milk production without negative impact. Key Words: Calcium-Fatty Acid, Dairy Cow, Milk, Production, Quality

Sapindus rarak fruits have bioactive compound named saponin which are potential to inhibit growth of protozoa and reduce cholesterol. This study was conducted to evaluate effect of lerak (Sapindus rarak) powder as microparticle on performance and lipid profile of chicken broiler that was infected by Eimeria tenella. A total of150headsof DOCwere assign to recive on of5 treatments: T1 (K+, TAk, TSRa, TIE), T2 (K-, TAk, TSRa, IE), T3 (Sal, IE), T4 (Sra 2,5, IE), and T5 (Sra 1,25, IE); each treatment consisted of 6replications with 5birds per replications in battery cage for 34 days. All chickens except those in control positive treatment (non-infected, non-medicated) were inoculated orally with 6000 oocysts E. tenella on the 14th day of age. Variables measured were body weight gain, carcass, OPG (oocysts pergram of faeces), lipid profile, and mortality. Treatment with S. rarak, dose of 1.25g/kg was not significantly different from the salinomycin treatment on BWG and feed conversion. Percentage of carcassand organs and blood cholesterol concentration were not significantly differentin all treatments, but blood triglyceride at S. rarak addition with doseof 2.5, 1.25g/kg and salinomycin addition with dose of 0.5g/kg, and negative control were lower than positive control. While number of OPG in faeces (days 14-34) showed that S. rarak powder with dose of 2.5 and 1.25g/kg suppressed the development of oocystsof E. tenella. In conclusion, S. rarak microparticle (75Âµm) can be used as feed additive to replace salinomycinas coccidiostat.

It is reported that feedstuff preparation affects intake and digestibility of the ration. The objective of this experiment was to know the effect of physic conditions of Caliandra calothyrsus and its mixing with fresh Gliricidia sepium toward the digestibility and nutrient consumption of sheep. Fourty nine (49) thin tail sheep with the average body weight of 15.42 kg (SD 2.68) was randomly assigned into one out of five treatment groups of greenery feed which composed of different fresh Penisetum sp. (FP), fresh Caliandra calothyrsus (FC), fresh Gliricidia sepium (FG), dried C. calothyrsus (DC) and steamed C calothyrsus (SC). Treatment A (70% FP + 30% FC), B (70% FP + 30% FG), C (70% FP + 15% SC + 15% FG), D (70% FP + 15% DC +15% FG) and E (70% FP + 15% DC + 15% FG). The treatments had been carried out for 90 days. Water was given ad libitum. Parameters recorded in this experiment were nutrient consumption (dry matter/BK, crude protein, energy) and nutrient digestibility (BK, crude protein, energy). Data recorded were processed by covariant analysis with body weight of sheep at the early experiment treatment as a covariant. Results of the experiment showed that there were significant difference (P<0.05) between fresh, dried, and steamed C. calothyrsus and its mixing with fresh G. sepium toward the consumption and nutrient digestibility. The average of consumption and nutrient digestibility value were high in mixing treatment of 15% fresh C. calothyrsus with 15% fresh G. sepium.

The content of active compounds in natural materials is generally low and highly variable, thus requiring efficient and selective extraction methods. This study aims to evaluate a stepwise extraction process applied to the seeds, oil, and by-products of Nigella sativa (black cumin) to obtain thymoquinone (TQ) and other phytochemicals. The study consisted of four main stages: (1) extraction of HS oil using the cold press method, (2) stepwise extraction using 70% ethanol as solvent, (3) analysis of TQ content and phytochemical compounds in the extracts, and (4) evaluation of the antibacterial activity of habbatussauda oil extracts against pathogenic and non-pathogenic bacteria. Results showed that the cold press method yielded 34.46% oil. Stepwise extraction using 70% ethanol resulted in significant differences (p<0.05) in both yield and TQ content among the seed, oil, and by-product extracts. Among all samples, the ethanol extract from habbatussauda oil exhibited the highest yield and TQ concentration. Furthermore, at a concentration of 100 μg mL⁻¹, this extract inhibited the growth of pathogenic bacteria such as Salmonella typhimurium and Escherichia coli, without affecting non-pathogenic strains like Lactobacillus spp. and Bifidobacteria spp. In conclusion, stepwise extraction using 70% ethanol proved effective in enhancing TQ recovery and demonstrated potential as a phytobiotic agent with selective antibacterial activity against pathogenic bacteria.
