ABSTRACT. Usus adalah salah satu organ pencernaan yang berperan penting pada proses absorpsi nutrisi sebagai sumber energi. Penelitian ini bertujuan mengetahui histologi, histomorfometri dan histokimia sebaran glikogen pada usus ayam buras (Gallus gallus domesticus) sebelum dan setelah menetas menggunakan pewarnaan Haematoksilin-Eosin (HE) dan pewarnaan Periodic Acid Schiff (PAS). Sampel penelitian terdiri atas empat kelompok tingkat umur berbeda, setiap kelompok berjumlah enam usus ayam. Hasil penelitian menunjukkan perbedaan nyata (P˂0,05) morfometri usus ayam buras secara makroskopis. Secara histologis pada setiap perkembangan sudah terlihat lapisan usus yang terdiri atas tunika mukosa, submukosa, muskularis, dan serosa. Pada tunika mukosa, didapati tiga lamina yaitu lamina epitelia, propria, dan muskularis mukosa yang mulai teramati pada masa inkubasi hari ke-14. Lamina epitelia berupa sel epitel silindris selapis dengan mikrovili, lamina propria berupa jaringan ikat, dan lamina muskularis mukosa berupa berkas otot polos. Pada tunika mukosa dijumpai adanya sel Goblet dan kripta Liberkuhn yang teramati pada masa inkubasi hari ke-20 dan setelah menetas hari ke-7. Hasil histomorfometri ketebalan lapisan usus, panjang vili, lebar vili, dan diameter lumen usus ayam buras pada masa inkubasi dan setelah menetas menunjukkan perbedaan nyata (P˂0,05). Temuan reaksi positif kuat terhadap pewarnaan PAS dijumpai pada masa inkubasi hari ke-20 dan setelah menetas hari ke-7 dan positif lemah pada masa inkubasi hari ke-14. Dapat disimpulkan bahwa terdapat korelasi antara perkembangan usus ayam secara makroskopis, histomorfometri ketebalan tunika dan vili, serta sebaran reaksi positif kuat terhadap pewarnaan PAS pada masa inkubasi hari ke-20 dan setelah menetas hari ke-7.

Pemberian tepung tanaman obat di dalam ransum petelur tidak berpengaruh nyata pada jumlah folikel. Berat dan panjang organ reproduksi tidak dipengaruhi oleh perlakuan tepung tanaman obat. Berdasarkan hasil penelitian dapat disimpulkan bahwa penambahan 5% tepung daun Katuk, Marigold dan Senduduk dalam ransum menunjukkan konsumsi ransum, persentase produksi telur, egg mass production, konversi ransum, bobot dan panjang oviduk, berat ovarium dan jumlah folikel yang sama pada ayam petelur. (Efficacy of medicinal plants on production performance and reproductive characteristics of laying hens) ABSTRACT. Efficacy of Katuk leaf meal, Marigold leaf meal and Senduduk leaf meal on production performance and reproductive characteristics were evaluated. Forty layers aged 32 weeks were distributed into 4 dietary treatments. The layers were housed in individual battery. One-way ANOVA treatment arranged in a Completely Randomized Design was used in this experiment. Dietary treatments were P0 (control without medicinal leaf meal), P1 (diet with 5% Katuk leaf meal), P2 (diet with 5% Marigold leaf meal), P3 (diet with 5% Senduduk leaf meal). This research measured feed intake, egg production, percentage of egg production, feed conversion ratio, number of follicles, weight of ovary, weight and length of oviduct as parameters. Significant results were tested by Duncan Multiple Range Test. The result showed that dietary treatments of medicinal leaf did not affect feed intake and feed conversion ratio of layers. Egg production percentage and egg mass production, the number of follicles, and length and weight of oviduct were similar of all medicinal leaf meal treatments. It can be concluded that feeding medicinal leaf meal did not affect production performance, number of follicles and weight of reproductive organs.

ABSTRAK. Pucuk tebu dan titonia merupakan hijauan alternatif yang dapat digunakan sebagai sumber energi dan sumber protein pada ternak ruminansia, tetapi terkendala dengan adanya kandungan lignin dan zat anti nutrisi. Untuk itu dilakukan penelitian yang bertujuan untuk mengetahui pengaruh kombinasi pucuk tebu dan titonia fermentasi terhadap kecernaan fraksi serat (NDF, ADF, selulosa dan hemiselulosa) secara in-vitro. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan yaitu A (100% Pucuk Tebu Fermentasi + 0% Titonia Fermentasi), B (75% Pucuk Tebu Fermentasi + 25% Titonia Fermentasi), C (50% Pucuk Tebu Fermentasi + 50% Titonia Fermentasi), dan D (25% Pucuk Tebu Fermentasi + 75% Titonia Fermentasi) dengan 5 ulangan. Pengaruh perlakuan terhadap parameter yang diuji dianalisis menggunakan sidik ragam dan dilanjutkan dengan uji jarak berganda Duncan jika ada perbedaan antar perlakuan. Hasil sidik ragam menunjukkan bahwa perlakuan memberikan pengaruh yang berbeda sangat nyata (P0,01) terhadap kecernaan fraksi serat (NDF, ADF, selulosa dan hemiselulosa). Dari hasil penelitian dapat disimpulkan bahwa perlakuan C (50% Pucuk Tebu Fermentasi + 50% titonia Fermentasi) memberikan hasil yang terbaik terhadap kecernaan NDF (78,13%), ADF (76,76%), selulosa (80,81%) dan hemiselulosa (81,11 %). (In-vitro digestibility of fiber fractions combination of sugarcane tops and tithonia as ruminant feed) ABSTRACT. Sugarcane tops and tithonia are alternative forages that can be used as an energy source and protein source in ruminants, but are constrained by the presence of lignin and anti nutrients. For this reason, a study was conducted to determine the effect of a combination of fermented sugarcane tops and fermented tithonia on the digestion of the fiber fraction(NDF, ADF, cellulose, and hemicellulose).The research design used a randomized block design (RBD) with 4 treatments, namely A (100% fermented sugarcane tops and 0% fermented tithonia), B (75% fermented sugarcane tops and 25% fermented tithonia), C (50% fermented sugarcane tops and 50% fermented tithonia), D (25% fermented sugarcane tops and 75% fermented tithonia) with 5 replications. Effect of treatment on parameters tested using analysis of variance and continued with Duncan's Multiple Range Test (DMRT) if there are differences between treatments. The results of experiments showed that treatments gave a very significant difference (P 0.01) to the in-vitro digestibility of fiber fraction (NDF, ADF, cellulose, and hemicellulose). From the results of the study, it can be concluded that the treatment C (50% sugarcane tops fermentation and 50% fermented tithonia) gives the best results on the in-vitro digestibility of fiber fraction NDF (78,13%), ADF (76,76%), cellulose (80,81%) and hemicellulose (81,11 %).

Proteases are one of most important and abundant enzymes produced by the biotechnology industry, for scientific, physiological and industrial application and dominates of the whole enzyme market. Lactobacillus plantarum IIA-1A5 is an Indonesian lactic acid bacteria (LAB) isolated from beef Peranakan Ongole cattle. Preliminary analysis on its whole genome sequence indicated that this strain harbours some genes involved in protein degradation and might be promising to be further applied. This study aims to optimize the gene sequence of a lon-like protease of L. plantarum IIA-1A5 for heterologous expression system. The Lon-like gene expression system is made using genes that have been optimized first in silico. pET-28a(+), E. coli BL21(DE3), Nde1 and BamH1 were used in this study as a expression vector, a host and retriction enzyme, respectively. Molecular weight was validated using SDS-PAGE and expasy.org software. The results showed that optimization increased codon adaptation index value (CAI) and GC content to 0.97 and 56.57%, respectively, which were suitable for the E. coli expression system. The Lon-like IIA gene was successfully expressed in the cell cytoplasm by induction of 1 mM Isopropyl β-D-1-thiogalactopyranoside (IPTG) at 37 °C. As many as 88% of Lon-like IIA codons were distributed in the 91-100 quality group. Lon-like IIA was successfully expressed in a host cell induced with 1 mM IPTG at 37oC . IPTG induction was performed at the 3rd hour of incubation with OD600 0.59. In addition, Lon-like IIA molecular weight was detected approximately 43 kDa.

ABSTRAK. Tujuan dari penelitian ini adalah untuk mengidentifikasi pengaruh polimorfisme gen heat shock protein 70 (HSP70) terhadap sifat toleransi panas. Genotiping dilakukan pada 110 itik lokal dari 4 populasi itik Sumatera Barat (pitalah, bayang, kamang, dan payakumbuh). Enzim restriksi yang digunakan adalah SacII. Cekaman panas dilakukan selama 1 jam dengan sampel itik lokal sebanyak 24 ekor untuk menganalisa status hematologi. PCR-RFLP dan Sanger sequencing assay digunakan untuk mengidentifikasi polimorfisme. Analisis polimorfisme dilakukan dengan menggunakan Software MEGA 7 dan pengaruhnya dianalisis dengan ANOVA menggunakan software SAS 9.4. Produk amplifikasi yang dihasilkan yaitu 466 pasang basa. Lokus HSP70/SacII mengenali satu situs SNP (Single nucleotide Polymorphism) g.1702TC, menghasilkan dua alel (T dan C) dan tiga genotype (TT, TC, CC). Gen HSP70/SacII bersifat polimorfik pada semua populasi. Hasil penelitian menunjukkan bahwa alel T memiliki frekuensi yang lebih tinggi daripada alel C pada semua populasi. Analisis chi-kuadrat (χ2) menunjukkan bahwa semua populasi itik lokal memenuhi kaidah kesetimbangan Hardy-Weinberg. Pengaruh genotipe gen HSP70 terhadap status hematologi menunjukkan perbedaan (P0,05) terhadap nilai heterofil dan nilai H/L dengan genotipe CT menunjukkan toleransi panas yang lebih baik dibanding genotipe lainnya. Gen HSP70/SacII dapat dijadikan marka molekuler sifat toleransi panas pada itik lokal berdasarkan keragaman dan pengaruhnya terhadap status hematologi. (The effect of heat shock protein 70 (HSP70) SacII gene polymorphism on heat tolerance of West Sumatera local duck) ABSTRACT. The objective of this study was to identify the effect of HSP70/SacII gene polymorphism associated with the thermotolerance trait. Genotyping was performed on 110 local duck from the West Sumatera ducks population (pitalah, bayang, kamang, and payakumbuh). The restriction enzyme used was SacII. Heat stress was done for 1 hour with samples used as much as 24 birds to analyze hematological status. PCR-RFLP and Sanger sequencing assays were used to identify polymorphism. Analysis of polymorphism was conduct by MEGA 7 software and its effect is analyzed with ANOVA using Statistical SAS 9.4 software. The product of amplification was 466 bp. HSP70/SacII recognized one SNP g.1702TC, producing two alleles (T and C) and three genotypes (TT,TC,CC). The HSP70/SacII locus were polymorphic in all population. T allele had a higher frequency than C allele in all populations. The analysis of chi-square (χ2) showed that all local ducks population were fit with Hardy-Weinberg equilibrium. The effect of HSP70/SacII gene on hematological status showed differences (P0,05) of heterophil and H/L ratio with CT genotype show better heat tolerance than other genotypes. HSP70/SacII gene can be used as a marker of heat tolerance in local ducks based on polymorphism and its effect on hematological status.

Analysis of polymorphism was conduct by MEGA 7 software and its effect is analyzed with ANOVA using Statistical SAS 9.4 software. The product of amplification was 466 bp. HSP70/SacII recognized one SNP g.1702TC, producing two alleles (T and C) and three genotypes (TT,TC,CC). The HSP70/SacII locus were polymorphic in all population. T allele had a higher frequency than C allele in all populations. The analysis of chi-square (χ2) showed that all local ducks population were fit with Hardy-Weinberg equilibrium. The effect of HSP70/SacII gene on hematological status showed differences (P0,05) of heterophil and H/L ratio with CT genotype show better heat tolerance than other genotypes. HSP70/SacII gene can be used as a marker of heat tolerance in local ducks based on polymorphism and its effect on hematological status.","PeriodicalId":30910,"journal":{"name":"Jurnal Agripet","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46717182","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}

ABSTRAK. Progesteron merupakan hormon yang berperan penting dalam proses pemeliharaan kebuntingan dan dihasilkan oleh corpus luteum. Penelitian ini bertujuan mengetahui hubungan antara kadar hormon progesteron pada fase awal luteal dengan kematian embrio pada sapi Aceh. Dalam penelitian ini digunakan empat ekor sapi betina dewasa berumur 3-5 tahun, bobot badan 150-250 kg, sehat secara klinis, dan memiliki reproduksi normal. Sapi disinkronisasi menggunakan 5 ml prostaglandin F2 alfa (PGF2α) dengan pola penyuntikan ganda berinterval 11 hari. Koleksi sampel darah untuk pengukuran konsentrasi progesteron dilakukan pada hari ke-5, 6, dan 7 pasca inseminasi. Pengukuran konsentrasi progesteron dilakukan menggunakan metode enzymelinked-immunoassay (ELISA), pemeriksaan kebuntingan dan kematian embrio menggunakan metode transrektal ultrasonografi pada hari ke-25 pasca inseminasi. Pemeriksaan diulang setiap 10 hari sampai hari ke-55 pasca inseminasi. Puncak sekresi progesteron pada sapi bunting dengan embrio yang bertahan hidup terdapat pada hari ke-7 (2,082 ng/ml), pada sapi Late Embryonic Mortality (LEM) di hari ke-5 (8,209 ng/ml) dan pada sapi tidak bunting di hari ke-7 (3,051±1,157 ng/ml). Sekresi progesteron sapi LEM pada hari ke-5 sampai dengan ke-7 cenderung menurun sedangkan pada sapi yang bertahan hidup cenderung meningkat. (Correlation between progesterone levels in early luteal phase and embryonic death in Aceh cattle) ABSTRACT. Progesterone is an important hormone that functions to maintain pregnancy and is produced by the corpus luteum. The aim of this study was to see a correlation between progesterone and the incidence of embryonic death in Aceh cattle. This study used four adult female cows, 3-5 years old, 150-250 kg body weight, clinically healthy, and have a normal reproduction. The synchronized with 5 ml prostaglandin F2 alfa hormone, and double injection pattern with 11-day intervals. The blood was collected for progesterone measurements on 5th, 6th, 7th day post artificial insemination. Measurement of progesterone concentration was carried out using an enzymelinked-immunoassay (ELISA), while pregnancy and embryo mortality was performed using the trans-rectal ultrasonography method on the 25th day after insemination. The examination was repeated every 10 days until day 55th after insemination. Progesterone secretion peaks in pregnant cows were on day 7th (2.082 ng/ml), in cattle Late Embryonic Mortality (LEM) on day 5th (8.209 ng/ml) and in cattle not pregnant on day 7th (3.051±1.157 ng/ml). The pattern of LEM progesterone secretion on days 5th to 7th tends to decrease while those that survive tend to increase.
