Abstract

Abstract. Toxoplasmosis is a disease that infects all warm-blooded animals, including livestocks and humans caused by Toxoplasma gondii parasites. There are major drugs used for the therapy, though they have some effects to the patients, such as allergy, toxic and teratogenic for fetus. In addition, toxoplasmosis treatment is only effective for tachyzoites T. gondii in acute infection, while tissue cysts cannot be eradicated in chronic toxoplasmosis Tissue cysts of T. gondii contained in meat that are consumed by humans and meat-derived products may be important sources of infection for humans. Microneme protein (MIC) is one of proteins that belongs to excretory-secretory antigens (ESAs) of Toxoplasma gondii. Microneme 3 protein (MIC3) is the protein that plays an important role in the invasion process during cell infection as a mediator attachment parasite to the host cell. Recombinant MIC3 protein has been already used for the detection of toxoplasmosis and it could induce humoral and cellular immune response in experimental animals. The aim of this research was to express MIC3 recombinant protein of T. gondii from local isolate that was cloned into expression vector and transformed to E. coli BL21. In the future, recombinant protein MIC3 can be used for vaccine candidate and diagnostic tools for toxoplasmosis in animals and humans. Gene of MIC3 T. gondii local isolate (1.2 Kbp) was cloned into expression vector pET-32a(+) (5.9 Kbp) and transformed to Escherichia coli BL21. Protein from plasmid recombinant (7.1 Kbp) was expressed and performed by culturing recombinant bacteria into LB medium containing ampicillin and IPTG. Recombinant protein was isolated by sonication method and identified using SDS-PAGE. Finally, the recombinant protein was analyzed by immunoblotting using anti-ESAs polyclonal antibody. In conclusion, expression of the MIC3 gene with ~108 kDa has been successfully performed by cloning gene encoding for MIC3 protein of T. gondii local isolate that can be identified with polyclonal antibody anti-ESAs.Key Words: Toxoplasma gondii, expression, MIC3 protein

Abstract

RFLP analysis of mitochondrial DNA cytochrome b gene was conducted to determine the diversity, status and close genetic relationships in a population of Batur sheep with the Merino and local sheep breeds (Garut, Thin Tail and Fat Tail). The research used genomic DNA of 27 samples of Batur, 15 Merino, 17 Garut, 15 Thin Tails and 15 Fat Tails sheep. The PCR process used two types of 25 nucleotides primers. The PCR products were checked by using 2% agarose gel electrophoresis. The PCR DNA fragment was digested by using Hae III at 37 oC and incubated for 10 hours. Similarities and differences of cytochrome b gene RFLP bands between individual samples of one and across populations, genetic distance, and close genetic relationship, were identified. The PCR process of the cytochrome b gene metochondrial DNA of the 45 samples of sheep yielded 359 bp band types. The digestion (cutting) of the PCR products of mitochondrial DNA cytochrome b gene by using Hae III resulted in RFLP band profiles of 128 up to 231 bp polymorphisms of cytochrome b gene. Although the Hae III restriction enzyme recognized only one restriction site, however, between samples of Batur, Merino, Garut, Thin Tail, and Fat Tails, there were monomorphism and polymorphism Hae III loci.Key Words:  RFLP, cytochrome b gene, genetic markers, genetic similarity, Batur sheeAnimal Production 13(3):156-165 (2011)

Abstract

The present study was conducted to detect polymorphism of growth hormone (GH) gene in Ongole grade crossed with Simmental bull (SIMPO) and its association with growth traits. Blood samples of 62 cattle were taken from population of SIMPO cattle were located in the sub-province region of Bantul, Special Region of Yogyakarta. A 211 bp fragment of GH gene spanning from the forth intron region (49 bp) to fifth of exon (162 bp) was amplified and digested with AluI restriction enzyme to identified polymorphism at this locus. The resulted indicated that two genotypes LL and LV were found at the GH gene in SIMPO population cattle. The frequencies of L and V alleles were 0.82 and 0.18, respectively. In SIMPO calves, the average birth weight, 2 months body weight and daily body weight gains of LV genotypes were tend to higher than that of LL genotypes.

Abstract

The objective of the research was to evaluate the genetic varieties of k-Casein gene of Holstein Friesian (HF) in Koperasi Unit Desa (KUD) Karangploso, Dau, Ngantang and Pujon, Malang, East Java by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism Analysis (PCR-RFLP) using Pst-l.  The research used Holstein Friesian dairy cows raised by farmers of KUD Karangploso, Dau, Ngantang and Pujon, Malang, East Java. The blood samples were collected from 29 cows. The research activities were carried out by collecting cow’s blood, DNA extraction, and DNA amplification with PCR. PCR products were digested with Pst-l enzyme restrictions, then allele genes of k-Casein were identified. The frequency of allele and genotype of k-Casein gene were calculated by Hardy-Weinberg. The results showed that cows raised by farmers of KUD Karangploso, Dau, Ngantang and Pujon, Malang-East Java had two alleles k-Casein polymorphism, i.e. allele A (0,74) and B (0,26); therefore, two genotypes existed including AA (0,55) and AB (0,38). It can be concluded that genetic diversity of k-Casein gene existed in Holstein-Friesian dairy cows raised by farmers of KUD Ngantang, Pujon, Dau and Karangploso, Malang, East Java.

Abstract

Abstract. Chicken productivity is not only determined by body weight increase and feed efficiency but also disease resistance. Avian influenza (AI) is still an endemic in Indonesia. Highly mutative characteristic of AI causes unsuccessful vaccination to preventing chicken mortality; therefore, feed modulation alternatives are sought to raise body weight and body immune as well. Virgin coconut oil (VCO) contains fatty acid potential as antimicrobe and antivirus; VCO intake is therefore expected to increase chicken body immune. This research aimed at feed modulation to increase broiler chicken productivity. Forty broiler chicken of one day old (DOC) were used and the research applied Completely Randomized Factorial Design in which factor one was two vaccine levels namely AI-vaccinated chickens and AI-unvaccinated chickens. Factor two used four levels of VCO: 0, 5, 10, 15 mL/kg feed. DOC chickens were divided into eight treatment groups and repeated in five experiment units. Feed and water were given ad libitum. The result demonstrated that in spite of heterophile increase in AI-vaccinated VCO-given chickens, heterophile/lymphocyte ratio and feed intake were not significantly different among all treatment groups. With the highest body weight found in AI-vaccinated chickens given 10ml/kg feed VCO, it could therefore be concluded that VCO intake of 10mL/kg feed could raise body weight.Key words: heterophile, heterophile/lymphocyte ratio, feed intake, body weightAbstrak. Produktivitas ayam tidak hanya ditentukan oleh kenaikan bobot badan dan efisiensi pakan, tetapi juga ketahanan terhadap penyakit. Avian influenza (AI) masih merupakan wabah endemis di Indonesia. Sifat AI yang mudah bermutasi menyebabkan vaksinasi tidak selalu berhasil untuk mencegah kematian ayam, sehingga dicari alternatif modulasi pakan untuk meningkatkan bobot badan dan kekebalan tubuh. Virgin coconut oil (VCO) mengandung potensi asam lemak sebagai antimikroba dan antivirus, sehingga asupan VCO diharapkan dapat meningkatkan kekebalan tubuh ayam. Penelitian ini bertujuan untuk modulasi pakan untuk meningkatkan produktivitas ayam broiler. Empat puluh ayam broiler umur satu hari  (DOC) digunakan dalam penelitian yang menerapkan Rancangan Acak Lengkap Faktorial dengan faktor pertama dua level vaksinasi  yaitu ayam divaksin AI dan tidak divaksin AI. Faktor kedua adalah empat level VCO: 0, 5, 10, 15 mL  kg pakan. DOC ayam dibagi menjadi delapan kelompok perlakuan dan diulang dalam lima unit percobaan. Pakan dan air minum diberikan ad libitum. Hasilnya menunjukkan bahwa meskipun adanya kenaikan heterofil pada ayam yang divaksin AI dan diberi VCO, rasio heterofil/limfosit dan konsumsi pakan tidak berbeda secara signifikan pada semua kelompok perlakuan. Dengan bobot badan tertinggi ditemukan pada ayam yang divaksin AI dan diberi VCO 10 ml/kg pakan, maka dapat disimpulkan bahwa asupan VCO 10 mL/kg pakan dapat meningkatkan bobot badan. Kata kunci: heterophil, rasio heterophil/limfosit, konsumsi pakan, bobot badan EYW Yuniwartiet al/Animal Production 14(3):192-198, September 2012
