Study of Genetic Diversity of Native Indonesian Catfish Based on Nucleotide Sequences of the ND1 Gene

One of the native catfish to Indonesia is the baung fish (Hemibagrus). Baung fish are found in rivers in Sumatra, Kalimantan and Java. The catfish population is declining, thus conservation is needed to prevent extinction. To conduct an effective conservation efforts, molecular studies are needed to confirm the fish species from the three islands. Mitochondrial DNA is one of the markers that is often used to see the lineage and kinship of animals for conservation purposes. The purpose of this study is to determine the genetic diversity of the NADH Dehydrogenase Subunit I (ND1) gene catfish from each of these locations, can be used as a genetic marker. Samples were obtained from their natural habitat, namely Magelang (5), Palembang (3), Riau (2), Samarinda (2), 2 from Sintang, and 3 from Banjarmasin. The DNA of the fish sample was then isolated and then used as a template for amplification of DNA fragments using PCR techniques. Amplikon (PCR product) was then purified by gel extraction and then sequenced to determine the DNA sequence. The potential of DNA sequences as catfish genetic markers was proven by analyzing genetic diversity between species using the MEGA version 7.0 program (Kumar et al., 2016). The sequencing results 972 nucleotides composing the ND gene, and found differences in 268 nucleotide sites and 47 amino acid sites. Based on the nucleotide sequence of the ND1 gene, catfish from the Progo river (Magelang, Central Java), the Musi river (Palembang, Sumatra), the Kampar river (Riau), the Kapuas river (Sintang, Kalimantan), the Martapura river (Banjarmasin), the Mahakam river (Kalimantan) is included in the Hemibagrus sp.; catfish from the Elo river (Magelang, Central Java) belongs to the genus Mystus sp.; catfish from the Bengawan Solo river (Bojonegoro, East Java) belongs to the Pangasius sp

ANALYSIS OF APOLIPOPROTEIN-B (APO-B) GENE IN ATHEROSCLEROSIS MICE GIVEN CURCUMINOID EXTRACT OF ZANTHORRIZA IN ORAL

The aim of this study was to investigate the apolipoprotein-B (apo-B) gene in atherosclerosis mice which were orally given curcuminoid extract of Curcuma xanthorriza. A total number of 30 white mice were split into 6 groups, the first group considered as control (without any treatment), second group as atherogenic feed control, the third group as extract control, while the fourth, fifth and sixth groups as atherogenic feed and curcuminoid Curcuma xanthorriza extract group treated with 5 mg/mouse, 10 mg/mouse and 15 mg/ mouse, respectively for three months. The blood samples were taken from all six groups for the deoxyribonucleic acid (DNA) analysis using total DNA isolation, DNA amplification with polymerase chain reaction (PCR), and DNA sequencing. The data analysis showed that 374 bp nucleotide sequence gen of apo-B from Rattus norvegicus in groups B, C, D, E, and F did not cause any changes in genes. The analysis showed the sequence of apo-B Rattus norvegicus gene in the treatment group was apparently identical with that of Rattus norvegicus group A as the control group without treatment. As conclusion, the administration of curcuminoid zanthorrizza to atherosclerosis mice did not change the gene structure of apo-B 100

Refeeding Postmolting Method to Improve Weekly Production Performance of Rejected Laying Hens with Low Mortality

This research aimed to investigate the influence of gradually feeding rejected laying hens after molting on the performance of production. This research used 6,000 rejected laying hens of 80 weeks old in Subur Farm. Molting method was a modification method by reducing the feed gradually. At the beginning of this research, the feed was given 120 g/laying hens/day and it would be reduced by 10 g/laying hens/day until it reach 50 g/laying hens/day. In the next phase, all chickens fasted for seven days then the chicken was given 10 g/laying hens on the first day. The feed was increased 10 g/laying hens every two days up to 120 g/laying hens/day. Data Collection of Feed conversion ratio (FCR), mortality rate, amount of feed, and egg production were taken at the start of re-feeding. The results showed that during the period of molting until refeeding, mortality was 3.6%, an increase in egg production was seen since week 1, peak of production was 78% at week 9 with FCR 2.3.  The results of statistical analysis showed significant differences (P<0.05) on the percentage of egg production between time periods after the treatment of feed reduction. As the conclusion, molting followed by refeeding in rejected laying hen influences weekly production performance by extending peak production period, optimal FCR and daily egg production

This study was aimed to determine the secure level of the n-hexane extract of kebar grass on hypercholesterolemia rats based the acute oral toxicity test. Based the literature, no report on the toxic dosage before, initial dose was started at 300 mg/kg body weight (BW) and to be increased 2000 to 5000 mg/kg BW. Toxicity data were set for 24 hours and continued until 14 days after treatment for several parameters, i.e : toxicity symptoms, death of animals, changes in body weight and the manifestation of toxicity effects. At the end of the test, the rats were sacrificed and organs were taken for abnormalities (macroscopy). The results of this study showed that the administration of the n-hexane extract of grass kebar at all doses did not show the toxicity symptoms, mortality and body weight change. The absolute and relative weights and gross pathology observation of the internal organ were normal. Conclusions: the n-hexane extract of grass kebar is safe and the LD was determined on category 5, 50 unclassified or minimum practically non toxi

Beak Line and Eye Alignment as Phenotypic Sexing for Domestic Canaries (Serinus canaria)

Phenotypic sexing of birds is a common practice among the songbird-keeping community, yet it is based on non-reputable information. This study aims to determine the sex of canaries (Serinus canaria) based on the alignment of the eye with the beak line. A total of 26 samples, consisting of six samples of one-month-old canaries (three males and three females based on PCR examination), 20 samples of six-month-old canaries (ten proven breeding pairs) were used in this study. The birds' heads were photographed from the sides, and then the positions of the eyes were compared with the shadow alignment of the beak. The results provided that five young birds and ten adult birds have a beak line alignment under the eye, while ten adult birds and one young bird have a beak line alignment across the eye. The accuracy of sexing using this method was 100% for both female and male adult canaries. However, this result could not be applied to sample that are not yet sexually mature, as two young male birds were found to have beak alignment below the eye. It can be concluded that sexing adult canaries can be performed by observing the eye and beak line's alignment
