The objective of this study was to investigate the effect of Citrus aurantifolia extract (CAE), coconut shell liquid smoke (CSLS) and the combination of CAE and CSLS (CACS) on se’i characteristics. A completely randomized design was assigned in this experiment. Treatments used were: se’i treated with 5% (v/v) CAE, CSLS 5% (v/v), (CAE : CSL 1:1) )/ (CACS) and untreated se’i as a control (C). Parameters measured were: aroma, color, taste, pH, residual nitrite, total bacterial count, Coliform, Staphylococcus aureus, Escherichia coli, and Salmonella. The data of aroma, color, and taste were analyzed by using Kruskal-Wallis test followed by Mann-Whitney test. The pH, residual nitrite, and bacterial data were analyzed with analysis of variance (ANOVA) followed by least significant differences test. Results showed that CAE caused the highest score at both aroma and taste (P<0.05). CSLS caused the lowest residual nitrite (27 ppm) (P<0.05). Application of CAE and CACS could reduce total bacteria (P<0.05) at least 1 log. Color, pH, and Coliform number were not significantly different. S. aureus, E. coli, and Salmonella were negative in all se’i samples. CAE gives the best organoleptics and bacteriological characteristics while CSLS is more effective in reducing nitrite.Key words: Citrus aurantifolia extract, coconut shell liquid smoke, se’i, smoked beef

Dates fruit waste (DFW) is a by-product of dates juice industry that contains high energy. So, it is suitable for an energy source in dairy goat ration. This study was conducted to observe the effect of DFW utilization in the ration on energy partition and productivity of lactating dairy goats. The experimental design was randomized block design using 9 primiparous lactating dairy goats. There were three types of ration as treatments used in this study, i.e. R0= 35% forage + 65% concentrate, R1= 35% forage + 55% concentrate + 10% DFW, and R2= 35% forage + 45% concentrate + 20% DFW. Data were analyzed using ANOVA and polynomial orthogonal test. The evaluated variables were dry matter intake (DMI), energy partition including energy intake, digestible and metabolizable energy, fecal and urine energy, energy in methane gas, and energy in milk, milk production and quality. The results showed that the linear decreased of DMI, energy intake, digestible energy, metabolizable energy, and urine energy with the increased of DFW level in the rations. The use of 10% DFW (R1) showed the lowest energy loss through feces and methane gas of all treatments about 1089.57 kcal/head/d and 2.36 kcal/head/d, respectively. The use of DFW did not affect energy retention in milk. The utilization of DFW in ration did not significantly prevent the decline of milk production and milk quality. It can be concluded that DFW can be used as an alternative feed for the lactating dairy goat up to 10% in the ration.

This research aimed to increase functional value of broiler-chicken meat containing high antioxidant and low cholesterol through substitution of soybean meal (SBM) with Indigofera zollingeriana top leaf meal (ILM). The experiment used 160 day old broiler chicken (Cobb strain). The experimental chicken were provided dietary treatments when they were 15-days old (initial body weight of 460.5±1.56 g/bird) and terminated on day 35. A completely randomized design (CRD) with four treatments and four replications and ten birds in each replication was used in this experiment. Dietary treatments were: R1= diet containing 20% soybean meal (SBM) without I. zollingeriana top leaf meal (ILM); R2= diet containing 16% SBM and 5.9% ILM; R3= diet containing 12% SBM and 11.8% ILM; R4= diet containing 8% SBM and 17.74% ILM. Variables measured were performances (feed consumption, body weight gain, and feed conversion) and the quality of broiler meat (cholesterol, fat content, and malondialdehyde [MDA] concentration). The results showed that supplementation of 17.74% ILM (R4) as the substitution of 60% soybean meal protein produced the same performances of broilers as those of control diet (R1). Supplementation of 11.8% ILM as the substitution of 40% soybean meal protein (R3) decreased meat cholesterol by 34.70%, meat fat content by 52.93%, and MDA concentration by 62.52%. The conclusion of this study was that supplementation of 17.74% ILM produced the same performances as that of control diet, increased antioxidant content of the meat, indicated by a lower MDA concentration, and decreased cholesterol, as well as fat content of broiler-chicken meat.Key words: broiler performance, cholesterol, Indigofera zollingeriana, malondialdehyde (MDA)

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexiacalis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. The types of rations were: Ration A= 45% fermented kumpai grass + 40% benggala grass + 15% concentrate + 0% lamtoro leaf, Ration B= 45% fermented kumpai grass + 30% benggala grass + 15% concentrate + 10% lamtoro leaf, Ration C= 45% fermented kumpai grass + 20% benggala grass + 15% concentrate + 20% lamtoro leaf, and Ration D= 45% fermented kumpai grass + 10% benggala grass + 15% concentrate + 30% lamtoro leaf. The supplementation of lamtoro leaf up to 30% into the ration could increase (P<0.05) dry matter and organic matter intakes, and crude protein digestibility. The highest body weight gain and feed efficiency were found in Bali cattle fed ration with 20% lamtoro leaf supplementation. The level of lamtoro leaf supplementation in the ration did not affect the digestibility of dry matter, organic matter, and crude fiber. It was concluded that the supplementation of lamtoro leaf in the ration could increase dry matter, organic matter, and crude protein intakes. Addition of 20% lamtoro leaf gave the best effect on the increased body weight gain and feed efficiency in Bali cattle.Key words: Hymenachne amplexiacalis, Leucaena leucocephala, productivity, Bali cattle

The objective of this study was to determine the effect of piperine as a phytogenic feed additive on quail performances and egg quality. The experiment used a completely randomized design with five treatments and four replications and used ten quails with one week of age in each replication. The piperine was added to the diets at concentrations of 0 (T0), 15 (T1), 30 (T2), 45 (T3), and 60 mg/kg body weight (T4) for 8 consecutive weeks. The results showed that addition of 60 mg/kg body weight (T4) of piperine significantly (P<0.05) reduced feed consumption, egg production, egg mass, income over feed cost (IOFC), and increased water consumption as compared to the other treatments. The addition of 15-60 mg piperine/kg body weight significantly (P<0.05) reduced eggshell weight and increased egg yolk color score. The conclusion of this experiment was that the addition of piperine at 15-45 mg/kg body weight could be used as phytogenic feed additive to improve performance, IOFC, haugh unit, and yolk color.Key words: egg, feed additive, phytogenic, piperine, quail

This study was aimed to analyze neutral detergent insoluble crude protein (NDICP) and acid detergent insoluble crude protein (ADICP) contents of various commonly used forage and concentrate feedstuffs in Indonesia. A number of forages and concentrates, i.e. gliricidia, trichantera, indigofera, calliandra, papaya leaves, cassava leaves, leucaena, rapeseed meal, corn gluten feed, soybean meal, copra meal, palm kernel meal, fish and bone meal and wheat bran were subjected to proximate analysis, cell wall nitrogen determination and in vitro rumen fermentation evaluation. Chemical composition analysis was done in duplicate. The in vitro incubation was conducted in 14 treatments and 3 replicates by following a randomized complete block design. Variables measured after the incubation were total volatile fatty acid (VFA), ammonia, dry matter digestibility (DMD), organic matter digestibility (OMD) and crude protein digestibility (CPD). Results revealed that among the forages, cassava leaf had the highest proportion of NDICP while corn gluten feed was the highest among the concentrates. Different from that of NDICP, the highest proportion of ADICP was obtained in papaya leaf and copra meal for the forages and concentrates, respectively. Higher proportion of NDICP tended to decrease CPD (P<0.1). Although higher ADICP apparently tended to decrease CPD as well, the relationship was insignificant due to the higher variation of the dependent variable. It was concluded that cell wall protein proportion in feed may be used as an indicator to determine the quality of protein and its utilization in the rumen.

Mare’s milk has good nutrient composition for human being in the form of natural milk or milk products. It can be used to replace cow’s milk, especially in the regions outside of Java Island which are rarely found dairy cow. This study had an objective to develop fermented mare’s milk by using mixed cultures of probiotic bacteria i.e. Lactobacillus acidophilus (A), Bifidobacterium longum (B), and Lactobacillus casei (C). The cultures of two probiotic bacteria AB and BC had been developed as well as three probiotic bacteria ABC culture. The mixed cultures (AB, BC and ABC) were prepared in single culture then cultivated in mixed culture as total 10% v/v of mare’s milk used and was incubated at 39°C for 9 h. The pH, acidity and bacterial count, each of them was analyzed in every 3 h of incubation time, while the organic acid and sensory tests were conducted at the end of 9 h of incubation. The results showed that the growth of mixed probiotic bacteria culture BC and ABC had better pH value that was around 3 compared with AB around 4.5. This showed that the cooperation between bacteria was different in each different combinations. The number of bacteria also increased sharply between 3-6 h of incubation time and 6-9 incubation time (AB and BC) along with the increased lactic acid, but the acetic acid decreased from 1750 mg/L to 1500 mg/L. The result of sensory test showed low acceptability of trained panelists. It is concluded that mixed cultures, using two or three probiotic bacteria (L. acidophilus, B. longum, and L. casei) could grow in mare’s milk. The change of the biochemical patterns indicated a commensalism cooperation among bacteria used. It was therefore the fermented mare’s milk using these probiotic bacteria were not well accepted by entrained panelists.
