  • Supplementation of Follicle Stimulating Hormon Into In vitro Maturation
           Medium to Increase Oocytes Maturation and 4 Cell Stadium Embryo
           Development of Bligon Goat

    • Authors: Yanuar Achadri, Sigit Bintara, Diah Tri Widayati
      Abstract: The study was carried out to investigate the effect of follicle stimulating hormon (FSH) into in vitro maturation medium to increase oocytes maturation and 4 cell stadium embryo development of Bligon goat. Goat ovaries were obtained from a slaughterhouse and transported to the laboratory in a flask of NaCl at temperature of 31 – 34°C. Oocytes were aspirated from 2 – 6 mm of follicles into a 3 mL syringe (23G needle) that contained Dulbecco’s Phosphate-Buffered Saline. Oocytes were divided into three groups, i.e tissue culture medium (TCM) with FSH supplementation 0, 50, and 100 IU/mL. Oocytes were put into those medium and incubated on 39°C, 5% CO2, and 95% humidity for 24 hours. Matured oocytes were fertilized with capacitated frozen thawed-semen and incubated on 39°C, 5% CO2, and 95% humidity for 5 hours. Fertilized oocytes were washed for 3 times in TCM and incubated in the same condition for embryo culture. The data of FSH supplementation and embryo development were analyzed using randomized completely one way classification. The results showed that the percentages of mature oocytes from FSH supplementation 0, 50, and 100 IU/mL were 70,48±23,22, 78,48±15,80, and 80,29±12,86%, respectively. Cleavage rate of the two cells stage were 36,00±14,22, 44,00±33,94, and 57,45±31,78%, respectively, and for the 4 cells stage were 27,33±22,04, 35,33±40,73, and 39,45±20,38%. It is concluded that supplementation of FSH in the maturation medium could not increase the percentages of in vitro maturation and embryo development.

  • The Quality of Boer Goat Semen Preserved with Sugar Palm Juice

    • Authors: Muhammad Rizal, Muhammad Riyadhi, Abrani Sulaiman
      Abstract: The objective of this study was to examine the effect of seminal plasma on viability of Boer goat spermatozoa and effectiveness of sugar palm juice as an alternative extender during preservation at 5ºC. Semen of two Boer goats were collected using an artificial vagina. Fresh semen were evaluated and divided in equal volume into four tubes. Semen in the first and second tubes diluted with 80% sugar palm juice + 20% egg yolk (P1) and Andromed (P2), respectively. Semen in the third and fourth tubes were centrifuged with 3,000 RPM for 20 minutes, and the supernatant removed. diluted with 80% sugar palm juice + 20% egg yolk (P3) and Andromed (P4), respectively. Diluted-semen were preserved in refrigerator at 5oC, and quality of the spermatozoa including motile spermatozoa (MS), live spermatozoa (LS), and intact plasma membrane (IPM) were evaluated every day for four days. Results of this study showed that at day-2 preservation, mean percentages of MS, LS, and IPM for P2 (72, 83.4, and 83.4%), P3 (72, 82.6, and 82.2%), and P4 (72, 83, 83.8%) were significantly (P<0.05) higher than P1 (3, 24.8, and 25.2%). At day-3 preservation, mean percentages of MS, LS, and IPM for P2 (57, 65.6, and 69.6%) was significantly (P<0.05) higher than P3 (21, 34.8, and 31.8%), P4 (22, 33.6, and 31.2%), and P1 (0, 0, and 0%). In conclusion, semen of Boer goat to be preserved with extender containing egg yolk should be removed seminal plasma. Sugar palm juice containing egg yolk could be used as an extender for Boer goat semen, but should be applied in the AI program immediately after the semen is diluted.

  • The Effect of Corn Substitution with Palm Kernel Meal Treated by Enzyme on
           Production Performance and Carcass Quality of Broiler

    • Authors: Muhammad Halim Natsir, Irfan Djunaidi, Osfar Sjofjan, Antonius Suwanto, Esti Puspitasari, Ludovika Jessica Virginia
      Abstract: The research was aimed to evaluate the effects of substitution level of corn with palm kernel meal (PKM) untreated and palm kernel meal (PKM) treated by enzyme on production performance and carcass quality of broilers. The method used in this research was experiment using nested of completely randomized design with 2 factors, the main factor was type of palm kernel meal factors consisting of PKM without enzyme (B1) and PKM by mannanase enzyme (B2), and substitution corn level L0 (without substitution), L1 (12.5%), L2 (25%), L3 (37.5%) and L4 (50%). The different among the treatments were tested by Duncan’s multiple range test. The results showed that corn substitution with PKM untreated and PKM treated by enzymes was significantly effect (P<0.01) on feed conversion ratio (FCR), tenderness, meat cholesterol of broilers and income over feed cost (IOFC) and significant effect (P<0.05) on feed intake, but there is no significant difference on body weight, percentages of abdominal fat and water holding capacity (WHC). Furthermore, effect of level corn substitition with PKM nested to PKM untreated and PKM treated by enzyme was significantly effect (P<0.01) on feed intake, body weight, FCR, and tenderness and significant effect (P<0.05) on IOFC, but there is no effect on percentages of abdominal fat, WHC and meat cholesterol. It can be concluded that the corn substitution with PKM treated by enzymes was better than the PKM untreated on production performance and carcass quality of broilers. The optimal level of PKM untreated as corn substitution was 12.5%. While replacement with PKM treated by enzyme can be used up to 25%.

           Fed Contain Lauric Acid and Areca vestiaria Giseke

    • Authors: Jola Josephien Mariane Roosje Londok, Sumiati Sumiati, I Komang Gede Wiryawan, Wasmen Manalu
      Abstract: The objective of the study was to determine antioxidant enzyme activity and concentration of malondialdehyde on broiler which consumed feed containing lauric acid and natural antioxidant from Areca vestiaria Giseke. The study used 240 day-old chicks of Lohmann MB 202 P strain placed randomly at 24 experimental cage units (10 chickens each) of the litter system. The average temperature of the cage at the study was 25.80 to 32.080 C with relative air humidity rate of 67.69 to 86.20%. The research method followed a Factorial Completely Randomized Design 2 x 4 with 3 replications. The first factor was the source of lauric acid in feed, i.e. conventional coconut oil (CO) and pure lauric acid (LA). The second factor was the source of antioxidant in the form of dosage of Areca vestiaria (AV) and vitamin E supplementation (TF) with four levels of AV, ie 0, 625 mg.kg-1, 1250 mg.kg-1, and TF at a dose of 200 mg .kg-1 feed. Feed and drinking water were given ad libitum. Meat sampling to measure SOD, catalase and MDA was taken at the end of the study by first chickens were fasted for ± 8 hours (overnight). The sample used was right breast meat of experimental male chicken. The data were average from three experimental chickens. The data obtained were analyzed for the variant with the general linear model on MINITAB (version 16), then tested the differences between treatments using Tukey's honestly significant difference (HSD). The results showed that the source of laurate had a significant effect on SOD, catalase, and MDA, while antioxidant concentration significantly decreased SOD and MDA compared with control. The interaction between lauric sources and antioxidant concentrations affected catalase and MDA. The use of coconut oil as much as 3% and antioxidant supplementation of Areca vestiaria Giseke in feed at a dose of 1250 mg kg-1 could decrease lipid oxidation product of meat to produce a healthy food product.

  • The Utilization of Different Protein Sources as Soybean Meal Substitution
           in the Flushing Diet on Reproductive Performances of Doeling

    • Authors: Yulia Dwi Putri Aidismen, Dewi Apri Asturi
      Abstract: This research aimed to evaluate the effect of different protein sources (plant or animal source) as substitution of 50% soybean meal protein in the flushing diet on early reproduction performances of doeling. The treatments were three types of flushing diet, i.e., Control diet containing soybean meal (C), diet containing Indigofera meal (IM), and diet containing cricket meal (CM). Diet IM and CM were substitution of 50% soybean meal protein in the ration. Completely randomized design was used with three treatments and four replications by using twelve Sapera doeling. The experiment with flushing diet was done started from three weeks before mating (including adaptation), during mating and following one month after pregnancy. Parameters measured were nutrient consumption, BCS, plasma glucose, cholesterol, progesterone hormone and reproductive performance. The results showed that treatments of utilization of different protein sources were not significantly affected the feed consumption, BCS and reproductive performances of doeling, but it had significant effect (P<0.05) on plasma glucose and cholesterol. The protein source of Indigofera and cricket meal showed in improving of progesterone status to support until 30 days pregnancy. Diet containing cricket meal could improved onset estrous and duration of estrous. It was concluded that cricket meal can be used as an alternative protein source to substitute of 50% soybean meal protein in the Sapera doeling flushing diet and it can improve the reproductive performances.

  • Effects of Four Essential Oils on Nutrients Digestibility of In Vitro
           Ruminal Fermentation

    • Authors: Asih Kurniawati, Widodo Widodo, Wayan Tunas Artama, Lies Mira Yusiati
      Abstract: This research was done to study the effect of four essential oils (EOs), as feed additives, on ruminal nutrient digestibility in order to find out candidate of rumen modifier. Those four EOs were destilated from Foeniculum vulgare (Mill), Pinus merkusii (Jungh. & de Vriese), Cymbopogon nardus (L.) Rendle and Melaleuca leucadendra (L.). Their effect on dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF) digestibility were studied using in vitro rumen fermentation technique according to Theodorou method. Data were statistically analysed using analysis of variance factorial 4x5 design. Feed for fermentation substrate consist of Pennisetum purpureum, rice bran and wheat pollard. Essential oil individually was added and mix with substrate to meet the final concentration in fermentation media of 0, 100, 200, 400 and 800 mg/l. P. merkusii, C. nardus and M. leucadendra EOs reduced DM, OM, and CF digestibilities. The decreasing were in line with the increasing of EOs doses. Therefore F. vulgare only reduced CF digestibility. The value of DM, OM and CP digestibilities in fermentation with F. vulgare did not differ from control. CP digestibility differed among EO treatments. In F. vulgare, and P. merkusii, treatments, CP digestibility did not differ from control, whereas overall CP digestibility in C. nardus tended to be higher than control and CP digestibility in M. leucadendra was significantly higher. All EOs addition reduced CF digestibility at all level. CF digestibility in fermentation added 800 mg/l of M. leucadendra EO was slumped to only 14.29% of control. Among four EOs M. leucadendra is the most potent on interrupt rumen feed fermentation whereas P. merkusii and C. nardus in moderate ways and F. vulgare in delicate manner.

  • Biosorption of Metal Ions on Methanol Dehydrogenase Enzymatic Activity of
           Bradyrhizobium japonicum USDA110

    • Authors: Novita Kurniawati, Ambar Pertiwiningrum, Yuny Erwanto, Nanung Agus Fitriyanto, Mohammad Zainal Abidin
      Abstract: This research aims to understand the effect of metal ions bioabsorption which belong on different elemental groups to the methanol dehydrogenase (MDH) enzymatic activity in nitrogen-fixing bacteria Bradyhizobium japonicum USDA 110. Ten metal ions with each have 30μM concentration were added to grow Bradyhizobium japonicum USDA 110 in 10-1 diluted nutrient medium. The MDH activity test showed a similar result between the bacteria grown in medium without metal ions addition (control) and the bacteria were grown in a calcium ion/Ca2+ added media. The highest MDH enzymatic activity was shown on the bacteria grown in a magnesium/Mg2+ added medium, which showed 0.08 (U/mg) enzymatic activities. The addition of magnesium/Mg2+ metal ion accelerates the bacterial growth by 2.6 times and MDH activity by 1.28 times compared to control. The MDH enzyme is essential, especially for bacteria which exist in the soil environment, to adapt to high methanol concentration and to support bacterial anaerobic growth capacity along with plant symbiotic process. Moreover, the MDH activity staining method could also act as pollutant indicators like metal ions and hydrocarbon derivates. This research concluded that metal ions biosorption (calcium/Ca2+ and magnesium/Mg2+) are required for bacterial cells reproduction and oxidation of single carbon chain compounds like methanol. The nitrogen-fixing symbiotic bacteria, Bradyhizobium japonicum USDA 110 showed high MDH activity after the two metal ions absorption. However, contrary results were shown on vanadium/V3+, manganese/Mn2+, iron/Fe3+, copper/Cu2+, zinc/Zn2+, and aluminum/Al3+ absorption, which showed low MDH activity and cells biomass.

    • Authors: Fitra Yosi, Dyah Wahyuni, Meisji Liana Sari, Sofia Sandi
      Abstract: The aim of this research was to investigate the quality of physicochemistry and microbiology of Pegagan duck meat preserved with various concentrations of liquid smoke and storage time. This study used a complete randomized design (CRD) with a 4x2 factorial pattern. The first factor was the concentration of liquid smoke solution consisted of 4 levels, namely 2; 4; 6, and 8% (v/v). The second factor was the storage time which includes 2 levels ie 12 and 24 hours. The replication used was 4 times. The observed variables were physical quality of meat (water holding capacity, cooking loss, and tenderness), chemical quality (moisture content, protein content, and fat content), and microbiological quality (total microbes, pH, acid total, and total phenol). The data were processed by analysis of variance, followed by Duncan's multiple range test (DMRT). The results showed that there was a significant interaction (P<0.05) between liquid smoke concentration and storage time to water holding capacity, cooking loss, tenderness, fat content, total phenol, total microbial, total acid, and pH in Pegagan duck meat but did not show a significant interaction with other variables. It could be concluded that the optimum liquid smoke concentration was 4% and the optimal storage time was 12 hours.

  • Optimization of the Use of Farm Waste and Water Hyacinth for Earthworm
           (Lumbricus rubellus) Cultivation Media

    • Authors: Ulan Paluti Agustina, Agus Prasetya, Ambar Pertiwiningrum
      Abstract: This study aimed to determine the effect of water hyacinth addition to farm waste on the number of earthworms, earthworm weight, media shrinkage, vermicompost quality, and the sustainability and sensitivity of earthworm farming. The study was prepared using a completely randomized design with two different factors, the water hyacinth (media without water hyacinth and media with 5% water hyacinth addition) and raw materials from farm waste (chicken and cow manure, and biogas sludge from chicken and cow manure), with three replications for each treatment. The results showed that the addition of water hyacinth to raw materials from farm waste had a very significant effect on the number of earthworms, earthworm weight, media shrinkage, vermicompost quality (except for P2O5 level that had no significant increase). When manure is to be added to the cultivation media, it is recommended to use cow manure, while both types of biogas sludge (from chicken and cow manure) are good for the cultivation of earthworm. Based on the study of sustainability, the use of farm waste and water hyacinth as media to raise earthworm gives a positive value in economic and environmental aspects. Therefore, it has great potential.

           Model

    • Authors: siswanto imam santoso, Teysar Adi Sarjana, Agus Setiadi
      Abstract: This research aims to determine the performance and income of a closed-house broiler farm with partnership business model. The research was conducted in a closed broiler house owned by Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang, and in a partnership with Cemerlang Unggas Lestari Ltd. A total of 11,000 broilers were raised for each raising period in the closed broiler house. A case study method was used for this research. The data were collected using survey method; the primary data were collected directly through interviews with the farm operators and field observation. Secondary data were collected through data recording which includes production cost and obtained revenue in each raising period. The collected data were then analyzed through quantitative-descriptive study. A total 7 raising periods of production cost, revenue, and income in a year were analyzed. The results of this study showed that the average performances of closed-house broiler farm yield 0.37% depletion, 1.49 FCR, and 398.46 PI. The economic indicators showed that the average production cost was Rp292,668,800.00; which generated Rp327,300,779.00 revenue, Rp34,631,978.00 income, Rp183.055.535.00 NPV, and 1.24 BCR. The study concluded that the closed-house broiler farm generates higher income compared with the open house system.

  • Feasibility Study on Beef Cattle Development in Teluk Bintuni Regency,
           West Papua

    • Authors: Trisiwi Wahyu Widayati, Budi Santoso, Djonly Woran, Irba Unggul Warsono, John Arnold Palulungan
      Abstract: The purpose of this study was to obtain information on the readiness of the development of beef cattle using ranch system in Bintuni District, West Papua through the approach of four local foundations in terms of technical, social and economic. Research respondents were 62 families from four local foundations in Bintuni. Determination of technical feasibility of land used based on carrying capacity for each land. The technical feasibility of raising cattle was observed based on the knowledge of the community. Socio-economic feasibility was investigated based on food security and poverty level of society. Business feasibility was determined according to economic indicators namely B/C ratio, NPV, and IRR. The results showed that the aspect of land provided by the four foundations was feasible with the average carrying capacity based on fresh weight, dry matter and TDN basis were 1.8, 2.0 and 4.5 AU/Ha/year, respectively. About 70,91% of the farmers are free from poverty, and 46.54% are in food security status, which means that cattle raising will not be disturbed by the basic requirement of life but it needs an initial investment to support cattle raising. Based on the technical feasibility of cattle raising as much as 64,39% having no knowledge of breeding, therefore training and livestock education should be done. The business feasibility result shows that cattle raising on a breeding scale of 60 heads were feasible with positive NPV value of IDR 2.536.610,211, IRR of 23.09% and B/C of 1.22. Based on the overall indicators, it was concluded that the development of beef cattle in Bintuni regency was feasible to be done with requisite that improvement on land aspects and community knowledge about raising cattle.
