Effect of Ketapang Leaves (Terminalia catappa L.) Extract in Drinking Water on Performance, Hematological Indices and Immune Response of Kampong-Crossbreed Chicken During Starter Period
No full textThis study was aims to evaluate the potential of ketapang leaves extract (Terminalia catappa L.) as a feed additive on growth performance, haematological profile and immune respone in starter period of kampong-crossbreed chickens. Observations were made in vitro and in vivo. In vitro observations were carried out on the anti-bacterial activity, anti-fungal activity and antioxidant activity. In vivo observations were carried out on the growth performance, haematological profile and immunity response with the antigen test against NDV in starter period (4 weeks old). Two types of liquid extract are used, namely the liquid extract of fresh ketapang leaves and dry ketapang leaves. Ketapang leaves liquid extract is given in a mixture of drinking water with a concentration of 1, 2, 3 and 4% (ml / 100ml). The results showed that in vitro extracts of fresh and dry ketapang leaves had an effect on bacterial and fungal activity and antioxidant activity. In vivo observations showed no effect on performance, but had an effect on haematological profiles and immune respone. Dried ketapang leaf extract showed a better effect on haematology and immune respone.
The Effect of Milking Techniques on Escherichia coli Contamination in Cow's Milk in Jember
No full textMilk is a highly nutritious food but easily contaminated by bacteria. Those bacterias could be pathogenic. Staphylococcus aureus, Escherichia coli, and Salmonella sp. are pathogenic microorganisms. Milk contamination which occurs during the milking process can come from various sources such as cow skin, udder, water, soil, dust, humans, equipment, and air. Escherichia coli is a fecal contamination indication. and the possibility of enteropathogenic or toxigenic microorganisms so E. coli is known as a causative agent for diarrhea and foodborne illness. Milking machine usage can reduce the total plate count, maintain udder health, and cow nipples, and improve milk yield, milk quality, and udder health. Indonesian dairy farming still does a lot of milking by hand. The aim of the study was to determine the differences in E. coli contamination in cow milk because of modern milking and traditional milking techniques in Jember Regency. This is observational analytic research using a cross-sectional design with a total sample of 26. The study was conducted in December 2018. Contamination of E. coli in milk was tested using the MPN method, confirmation test using EMB, and Gram staining. Data analysis using bivariate analysis with chi-square test. The results of the study found E. coli contamination in 84.6% of modern milking techniques and 100% of traditional techniques. The conclusion of the study was that E. coli contamination in cow's milk because of traditional milking techniques was greater than that of modern milking techniques, but the results were not significantly different
Characteristics of Egg Yolk Powder Added Carrot Puree (Daucus Carota L.) and Isolated Soy Protein
No full textEgg powder is widely used in various industries, but the fat content in the egg yolks makes egg yolks powder more easily rancid due to oxidation. One way to inhibit the oxidation reaction of compounds is by adding antioxidants such as carrots. This research aims to evaluate the physicochemical properties, organoleptic properties, and antioxidant activity of egg yolk powder with the addition of carrot puree and isolated soy protein (ISP). The experimental design used in this study was a randomized block design (RBD) based on the manufacturing period, there were three groups of manufacturing periods. The results showed that adding carrot puree and ISP resulted in higher crude protein content and fiber content of egg yolk powder with the color and texture quality criteria preferred by the panelists. The addition of carrot puree and ISP did not affect the water content, pH, aw, and crude fat content. The addition of carrot puree in lower antioxidant activity than the control. Egg yolk powder with the addition of 15% carrot puree and 10% ISP gave the best results for the analysis of physicochemical properties, organoleptic properties, and antioxidant activity.

The Effect of Storage Temperature on Organoleptic and Physical Quality on Salted Smoked Eggs
No full textABSTRACT The purpose of this study was to determine the quality of salted smoke eggs which were stored at different storage temperatures of their physical and organoleptic qualities. The materials used in making salted smoke eggs are duck eggs, salt, bricks, and water. Methods of making the products are covering eggs with pasta or coating method, boiling eggs carefully, and smoking salted eggs until they are brown. Eggs are stored at different temperatures for 7 days including Storage at 5°C (refrigerator), Storage at 22°C (air conditioning), storage at ±28oC (room temperature), and Storage at 35°C (incubator). The results showed that salted smoke eggs stored at different temperatures had a significant effect (P<0.05) on taste and appearance but had no significant effect on aroma and air cavity. The conclusion of this study is that smoked salted smoke eggs with 7 days of storage are better if stored at incubator temperature and room temperature because, in 7 days of storage there has been no change in organoleptic quality.Keywords: different temperature, organoleptic quality, physical quality, salted smoke egg
Selenoprotein W1 (SEPW1) Gene Polymorphism and Association with Mineral Content in Sheep
No full textSelenoprotein W1 (SEPW1) is a protein containing selenium that has an important role in muscle growth and development by protecting myoblasts from oxidative stress. This study was aim to identify the diversity of the SEPW1 gene and its association with mineral content in sheep. The samples used were 100 sheep consisting of 10 samples of compass agrinak sheep (CAS), 15 samples of Javanese fat-tailed sheep (JFT), 30 samples of Javanese thin-tailed sheep (JTT), 25 samples of garut composite sheep (GCS), and 20 samples of jonggol sheep (JS). Selected mineral contents were determined using the IK method LP-04.10-LT-1.0. Identification of SEPW1 gene polymorphism will be conducted using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The size of the amplification product was 455 bp. Chi-square analysis showed that the population was in Hardy-Weinberg equilibrium. Polymorphism of the SEPW1 gene was found in each breed of sheep. The SEPW1 gene’s SNP g.53617063 A>G was significantly (
In Vitro Gas Production and Rumen Degradability of Lactating Dairy Cow’s Rations Containing Three Different Grasses
No full textThis research aimed to ascertain whether dwarf elephant grass (DEG) is compatible to substitute the common forages, viz. elephant grass (EG) and maize stover (MS) in the dairy cow rations (denote as R) using in vitro gas production (IVGP) technique. A completely randomized block design was applied to 4 feeding regimes and 3 replicates, viz. R1 consisted of 40% concentrate (C) + 30% MS + 30% EG; R2: 40% C + 30% MS + 30% DEG; R3: 40%C + 60% EG; and R4: 40% C + 60% DEG. The results showed that rations containing DEG improved both DM and OM degradabilities concomitant with increased in rumen efficiency of microbial protein synthesis (EMPS). Nevertheless, total and potential of gas production (GP) were higher in rations containing MS than other counterparts suggesting that there was a diverting usage of ROMD available for GP and EMPS. In conclusion, the use of DEG in dairy rations is recommended
