Physical quality and digestibility in vitro determination of green pellet concentrate based on Indigofera zollingeriana
Get PDFThis study aims to determine the physical quality and digestibility of green pellet concentrate based on I. zollingeriana. The composition of green pellet concentrate feed contains I. zollingeriana and C. calothyrsus in the following combinations: 1) I. zollingeriana /C. calothyrsus (90/0; R0), 2) I. zollingeriana/C. calothyrsus (75/15; R1), 3) I. zollingeriana/C. calothyrsus (60/30; R2) and 4) I. zollingeriana / C. calothyrsus (45/45; R3). The physical quality study of green pellet concentrate was performed using a completely randomized design with four types of green concentrate as treatments of three replications. Green pellet concentrate studies conducted in vitro rumen fermentation were performed using in a randomized block design with four treatments and three sources of liquid rumen as a block. The results of the experiments conducted with pellet criteria containing I. zollingeriana/C. calothyrsus composition (60/30; R2) have the best physical character (water activity = 0.58; particles size = 12.69 mm; degree value angles = 21.01°; collision endurance = 99.78%; endurance friction = 90.42 %; bulk density = 590 kg/m3) compared to the other treatments. The quality of diet based on digestibility in vitro, dry matter and organic material having a pattern equal to R0 is higher (P0.05) compared with other treatments, while the rough digestibility of In Vitro protein is seen R0, R1, and R2 (P0.05), but (P0.05) was higher than the treatment of R3. There was no difference of pH and total bacteria on green pellet concentrate type. The treatment of R3 has the lowest NH3, VFA and total gas concentration (P0.5) compared with R2, R1 and R0. It can be concluded that inclusion of Calliandra calothyrsus did not change physical quality of green pellets. However, increasing level of C. calothyrsus increased RUP and reduced digestibility, N-NH3, and total VFA
Correlation of electric conductivity values with the dairy milk quality
Get PDFMilk, as the prime source of food for mammals, has an electrolyte to replace the loss of body fluid caused by activity or metabolism process. The total electrolyte concentration can be measured based on conductivity value from the nutritional content. Therefore, the parameter of the quality of milk with conductivity value can be a benchmark for quality and selling value of milk, making it simpler to be implemented in the field. The aim of this research is to analyze the relation between electric conductivity (EC) with the content value of cow milk. The milk was taken from 10-30 cows from a farm in Lembang (district of West Bandung), Pengalengan (district of Bandung), Tasikmalaya, Sumedang, Subang, Sukabumi and Bogor of West Java Province. The milk was put in 50 ml of sterile falcon. The Probe EC count-meter CT-3031 was used to measure EC while the quality of milk was measured by Probe MilkoScanTMFT 120 (Foss). The milk quality is reflected by protein content, Fat, Total Solid (TS), Solid Non-fat (SNF), Lactose, Density, Acidity and Freeze Point Deviation (FPD). The results of this study show that the EC value in the milk gives a very real positive effect (p=0.01) to Total Solid (TS), Solid Non-fat (SNF), Lactose, and Freeze Point Deviation (FPD). The value of EC also significantly affect (p=0.05) the value of density in milk. Therefore, the value of EC can be used to predict the quality value of milk
Evaluation of LipL32 ELISA for detection of bovine leptospirosis in West Java
Get PDFThe current diagnosis of leptospirosis, micro Agglutination Test (MAT) and isolation, is expensive, impractical and technically demanding. This study was aimed at developing an ELISA based on recombinant LipL32 as a practical, inexpensive test for Leptospirosis. The DNA encoding LipL32 was isolated from Leptospira pomona, inserted into pRSET-C plasmid then expressed in E.coli BL21 as a poly-histidine-tagged protein. The amount of LipL32 protein, which was purified from the supernatant of lysed cells by a Ni-NTA column, was 1mg/l culture. This purified LipL32 was used as the coating antigen at 5µg/ml. The accuracy of ELISA was evaluated based on ROC analysis, by comparing the ELISA and MAT results of 517 bovine sera. Result in this study showed that the area under curve (AUC) was 0.853, which categorised the LipL32 ELISA as a “moderately accurate” test and indicates that the ELISA was able to differentiate positive and negative Leptospirosis serum. The result also showed ELISA LipL32 could detect serum positive MAT to Hardjo, Grippotyphosa, Tarrasovi, Rachmati and Bataviae. The optimal cut off for OD ELISA determined based on ROC curve was 0.504, and it showed sensitivity and specificity of ELISA LipL32 relative to MAT were 86.0% and 69.5%, respectively. Overall, the result in this study showed that ELISA LipL32 can be used as a rapid test for identification of anti-Leptospira antibodies in bovine
Serotype detection, molecular characterization and genetic relationship study on Pasteurella multocide local isolate
Get PDFPasteurella multocide is a bacteria that causes snoring disease or Haemorrhagic Septicaemia (HS) in Indonesia with high mortality and morbidity in heterogeneous species including cattle as a source of animal products with high economic value. The complexity of conventional and biochemical identification is a major obstacle in the detection of this disease because P. multocide has five serotypes A, B, D, E and F, while serotype B is the leading cause of HS cases in Asia including Indonesia. Therefore, it is necessary to conduct a research that can determine the serotype and molecular characterization and genetic study of five isolates of P. multocide from Lampung and Kupang by Polymerase Chain Reaction (PCR) technique. After PCR was performed on specific genes, capsular genes, 16S rRNA genes, sequencing and analysis using Bioedit, BLASTn, CLUSTALW and MEGA7.0.25, it was found that the five isolates were divided into two serotype groups: A and B. Isolate P. multocide (code: PMc) from Lampung is high homolog with ATCC isolate 12945, so it can be used as a positive control serotype A in the detection of other P. multocide isolates with PCR. Whereas, isolate P. multocide from Kupang can be used as positive control of serotype B because it is identical to P. multocide PMTB2.1 (CP007205.2) from Malaysia that is isolated from buffalo infected by HS
Effect of Techniques and Time of Sowing, Seed Rate, and Weed Management on Selcted Herbaceous Legumes Establishments in East Nusa Tenggara, Indonesia
No full textA series of experiments on techniques and time of sowing, and weed management of legumes Clitoria ternatea cv Milgarra, Centrosema pascuorum cv Cavalcade and cv Bundey, and Lablab purpureus cv Highworth, was conducted in East Nusa Tenggara (in the islands of Timor, Flores, and Sumba) in order to determine proper technique and time of sowing and weed management, which would be efficient in labor use and sufficient biomass production. Treatments of sowing techniques included dibble, furrow (covered and not covered), and broadcast (harrowed and not harrowed); while sowing time consisted of early wet season (December-January), mid of wet season (February-March) and the end of wet season (April-May), while weed managements consisted of weeded and unweeded treatments. The experiments employed block randomized design with four replications using plot sizes of 3 x 4 m to 4 x 5 m, depending on the availability of land for the experiments. The results of the experiments showed that the best sowing technique with the highest plant population at 4 weeks after planting was dibbling (42 plants/m²), followed by furrow, while the lowest plant population was obtained at the broadcast technique (9-20 plants/m²). Similarly, the highest biomass production was obtained in the dibbling technique (1.75 to 2.5 tons DM/ha per harvest at 12 weeks after planting in Ende, and 4-5 ton DM/ha in Nagekeo), followed by furrow technique covered or not covered (1-1.3 tons DM/ha in Ende and 3.5-4 tons DM/ha in Nagekeo), and the lowest in broadcast technique (0.3-1 ton DM/ha in Ende and 2-2.5 ton DM/ha in Nagekeo). However, considering the labor requirement and cost, it was recommended that furrow technique to suit the small farmer practices in the region. Weed management showed that weeded treatment (keep legume cleaned of weeds) gave significantly better (P0.05) biomass production compared with to that of unweeded treatment. It can be seen also that weed had more suppressing effects on Clitoria ternatea, compared to that of Lablab purpureus, especially when the plants were sown in the early wet season
Growth response of improved native breeds of chicken to diets differed in energy and protein content
Get PDFThe aim of doing this experiment was to observe the growth response of improved native breeds of chicken under diets differed in energy and protein content. Three groups of improved native breeds, obtained from mating of ♂KUB to ♀KUB (Line 1), of ♂SenSi to ♀KUB (Line 2) and of ♂Gaok x ♀KUB (Line 3), were subjected to three experimental diets, differed in metabolizable energy (ME) and crude protein (CP) content. The experimental diets consisted of Diet 1 (2,800 kcal ME/ kg with 17,81% CP), Diet 2 (2,950 kcal ME/ kg with 18,61% CP) and Diet 3 (3,100 kcal ME/ kg with 19,25% CP). The experiment was designed as factorial 3 x 3 with 7 replications of each treatment combination, consisted of 5 birds per treatment combination. The chickens were raised up to 10 weeks of age. Results of the experiment showed that Line 2 (♂SenSi mated to ♀KUB) had highest body weight at 10 weeks of age (P0.05), lowest feed conversion ratio (FCR) and highest European Production Efficiency Factor (EPEF), compared to other two lines. The appropriate diet for Line 2 was Diet 2. It could be concluded the crossbred line that was resulted from crossing of ♂SenSi to ♀KUB (Line 2), had potential to be used as improved native chicken for the industry in Indonesia supported by appropriate diet containing 2,950 kcal ME/kg with 18.61% crude protein
Exopolysaccharide (EPS) activity test of lactic acid bacteria (LAB) as immunomodulatory
Get PDFImmunomodulatory activity assay and characterization of exopolysaccharide (EPS) from Lactic Acid Bacteria (LAB) was done in Bogor. Bacteria used in this study was LAB strains of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus. Exopolysaccharide was extracted from L. delbrueckii subsp. bulgaricus and S. thermophilus then characterized with FT-IR spectrophotometer to determine the functional group. IR spectrum analysis using Fourier Transform-Infra Red (FT-IR) showed that EPS from both LAB isolates were carbohydrate compounds. Immunomodulatory activity in vivo from EPS was measured using phagocytic activity and phagocytic capacity macrophage cells from mice peritoneal cavity fluid. Exopolysaccharide were given orally to mice in concentrations of 100 μg/ml, 200 μg/ml and 300 μg/ml for 14 days then the mice were infected with Staphylococcus aureus. Result showed that EPS from both LAB isolate enhanced either phagocytic activity and phagocytic capacity macrophage cell from mice peritoneal fluid. EPS from L. delbrueckii subsp. bulgaricus concentration 300 μg/ml showed the highest phagocytic activity of macrophage cells and EPS from S. thermophilus concentration 300 μg/ml showed the highest phagocytic capacity. It is concluded that EPS potency tested as immunomodulatory derived from a culture of L. delbrueckii and S. thermophilus subsp.bulgaricus are able to increase the activity and phagocytosis murine peritoneal macrophages

Get PDFThe study was conducted to assess the knowledge, attitudes, practices (KAP), and financial losses of buffalo raisers due to Trypanosoma evansi infection (surra) and its control in Agusan del Sur Province. One-hundred and sixty (160) buffalo raisers from eight villages in four municipalities (towns) in Agusan del Sur, Mindanao, Southern Philippines were personally interviewed. Majority (63.65%) of respondents provided information about surra. Mean knowledge score of 12.54 was quite low to consider the respondents well informed about surra. Financial losses from mortalities among livestock in eight villages (in four towns) in Agusan del Sur amounted to 9.3 million Philippine Pesos (PHP) (US 10.7 M) of total financial losses among livestock in Agusan del Sur due to surra. In conclusion, buffalo raisers in Agusan del Sur Province lack adequate knowledge, attitudes and practices to effectively control surra, a disease that has caused high financial losses among livestock in the province
Contribution of legumes on phosphoric absorption by Panicum maximum cv Riversdale in intercropping system
Get PDFPhosphorus availability in soil as a mobile mineral influences forage growth. The purpose of doing this research is to enhance the soil phosphorus availability and grass production of Panicum maximum cv Riversdale by intercropping system with legums. The experiment was conducted based on with randomized design with five treatments of mixcropping of: (i) Gliricidia sepium + P. maximum; (ii) Calliandra calothyrsus + P. maximum; (iii) Leucaena leucocephala cv Taramba + P. maximum; (iv) Calopogonium mucunoides + P. maximum; (v) P. maximum as negative control. Plants were grown in pots with split-root technique using partition with a whole to allow some legume roots grew in the grass side. After growing for three months, on the legume areas 32P isotop solution was injected for 50 ml (11.23 μci/ml). After 21 days incubation samples were collected from both soil areas and both plants. The translocation of 32P was determined using geiger counter from legumes into the grass and the concentration of 32P was also determined in all plants. Forage productions was determined both in the legumes and grass. Result showed that soil phosphorus concentration in the grass area was significantly improved by intercropping with G. sepium and C. callothyrsus, while the one with L. leucocephala was similar, and the one with C. mucunoides was significantly lower than that of negative control (without legume). Detection of 32P showed that there was P translocation in the system. P. maximum grass production depending on kind of legumes (P0.05) those with G. sepium was significantly higher, L. leucocephala and C. callothyrsus were not significantly higher, while the one with C. mucunoides was 26.2% lower from the control although not significantly. However, C. mucunoides produced the highest forage from the legume plant. It is concluded that grass-legume intercropping had a positive impact on phosphorus soil concentration in the grass area and grass production. Kind of legumes influenced the effectivity
Chitosan nanoparticle of hCG (Human Chorionic Gonadotrophin) hormone in increasing induction of dairy cattle ovulation
Get PDFA controlled release delivery system of human chorionic gonadotropin (hCG) hormone helps to overcome the rapid degradation of hCG hormone in the blood, to avoid the use of multiple injections for ovulation induction and to enhance reproductive efficacy. This study aimed to prepare chitosan nanoparticles hCG (CS-NPh) and to determine its efficacy as nasal spray of CS-NPh. The observed parameters include physico-chemical characteristics of CS-NPh and the follicle size, corpus luteum, the time of ovulation and onset of estrus performed after administration of CS-NPh as a nasal spray compared with intramuscular hCG (control) at a dose of 1,000 IU in dairy cattle. The result showed that the formation of the hormone hCG nanoparticles is still in the size range of nanoparticles with a well and more stable molecular mass distribution, so it can be used as a carrier component of hormones. The result showed that the time of ovulation after hCG by intramuscular (day to 3.13±0.35) and CS-NPh as a nasal spray (days to 3.33±0.49) with the follicle size by 1.62±0.22 and 1.76±0.28 cm showed no significant differences (p 0.05), likewise the size of the corpus luteum and onset of oestrus. This indicates that administration of CS-NPh as a nasal spray can be used in enhancing the induction of ovulation in dairy cattles.Key Words: Nanoparticles, hCG, Nasal Spray, Ovulatio
