Sampling locations were determined by purposive sampling, including Kwala Bekala Market, Johor Market, and Tikung Market, with 90 samples. The working procedures included isolating bacteria from egg yolks using the pour plate method on SSA media, observing the bacteria morphology, calculating total Salmonella sp. colonies, Gram staining, and biochemical tests. The research results obtained indicated that the average total colonies of Salmonella sp. in Kwala Bekala Market were 1.45 x 105 CFU/g, in Johor Market they were 5.8 x 104 CFU/g, and in Tikung Market they were 3.6 x 104 CFU/g. The colony morphology of Salmonella sp. is circular and colourless, with a black spot in the center. The Salmonella sp. bacteria are Gram-negative with a red color, and are bacilli. Biochemical tests showed indole (-), MR (+), VP (-), SCA (+), and TSIA (+) test results. Based on the study results, it can be concluded that 4.44% of the positive samples were contaminated with Salmonella sp. in the traditional market of Medan Johor District and exceeded the BMCM in SNI 7388:2009.","PeriodicalId":33136,"journal":{"name":"Jurnal Sain Peternakan Indonesia","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135083987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used 120 blood samples of Bayang ducks in Kampung Binuang Dalam, Padang City, West Sumatra Province. Bayang duck blood samples were taken through the brachial vein for ± 1 mL. DNA extraction was taken from the blood using the Genomic DNA Purification Kit (Promega) Protocol. DNA was amplified using a pair of primers F: 5'- CCA GGA ATA TCT TTG GAA GCT GT-3 and R: 5'- TGC TAC GTT ACC AGC CTT GA -3 'which produced a 433 bp fragment of exon 3 IGF-1 gene, and F: 5'- CTG GAG CAG GCA GGA AAA TT - 3 'and R: 5'- TCC AGG GAC AGT GAC TCA AC -3' which produced 801 bp fragments of exon 4 IGF-1 gene. The amplification product was restricted by the DdeI enzyme, which recognized the C↓TNAG slashing site (N = G, A, T, C) for the exon three and MnII regions, which recognized the CAC↓GTG cutting site for the exon four regions. The cutting of the IGF-1 exon three gene product in Bayang ducks using DdeI as a restriction enzyme only recognized the C↓TNAG cutting site. The cutting results visualized with 2% agarose gel showed two genotypes: homozygous (+ / +) of 41 samples and the heterozygote (+/-) genotype of 60 samples. The cutting of the IGF-1 exon four gene product in Shadow ducks using MnII as a restriction enzyme only recognized the CAC↓GTG cutting site. The cutting results visualized with 2% agarose gel showed three types of genotypes, namely four samples homozygous (+/+), 67 samples heterozygous (+/-), and 49 samples homozygous (-/-). Based on the results of the study, it can be concluded that the IGF-1 gene in Bayang ducks is polymorphic, with the frequency of the IGF-1|DdeI genotype being in a hardy-weinberg imbalance, and the IGF-1|MnII genotype in a hardy-weinberg equilibrium.","PeriodicalId":33136,"journal":{"name":"Jurnal Sain Peternakan Indonesia","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135085658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basal diets were 60% elephant grass cv. Taiwan (Pennisetum purpureum cv. Taiwan) and 40% concentrate. The ration provision was three per cent dry matter of body weight. The observed parameters included feed consumption, feces production, dry matter digestibility, organic matter digestibility, crude protein digestibility, crude fat digestibility, crude fibre digestibility, nitrogen-free extract digestibility, and methane gas production. The research results indicated that the treatment did not significantly affect feed consumption (P>0.05) but did affect crude protein digestibility, crude fibre digestibility, nitrogen-free extract digestibility, and methane gas production.

The results showed that adding natural compounds improved broilers' growth rate, with the highest final body weight observed in the T5, 2459.78 g. Mortality rates did not differ significantly among treatments. The addition of natural compounds did not affect (P > 0.05) the relative weight of the immune organ, except the liver. The addition of natural compounds did not significantly affect blood parameters, including red blood cell count, white blood cell count, and haemoglobin levels (P > 0.05).

In conclusion, adding natural compounds to broiler litter can enhance broiler performance and health without adverse effects, promoting overall growth and reducing footpad dermatitis.","PeriodicalId":33136,"journal":{"name":"Jurnal Sain Peternakan Indonesia","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135721251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
