Abstract

The aim of the study was to produce polyclonal antibody (rabbit anti-ovPAG) which could detectPAG in the urine of pregnant ewes. Twelve rabbits were immunized against ovPG DEAE-TrisHCl (DT),DEAE-NaCl 20mM (DN2), DEAE-NaCl 40mM (DN4), DEAE-NaCl 80mM (DN8), DEAE-NaCl160mM (DN16), DEAE-NaCl 320mM (DN32) and DEAE-NaCl 1M (DN1) and NaCl 0.9 % as aplacebo. The 0.5 ml of isolate (purified from ovine cotyledon) was emulsified in equal volume withcomplete and incomplete Freud?s adjuvant. The mixture of each isolate and adjuvant was injected atmutiple sites along the dorsal area of rabbits by subcutaneous route. Blood were collected from marginalear vein, starting before first injection (baseline) and every 14 days. Rabbit anti-ovPAG were measuredusing Modified ELISA Technique. By using Western Blot Technique, DN32 showed the best immuneresponse among others and also could differenciate ovPAG in the urine of pregnant ewes It could beconcluded that ovPAG DN32 is a specific source of rabbit anti-ovPAG production. Protein of ovPAG atmolecular weight 31 kDa is a pregnancy protein marker of garut sheep and could be developed as amajor protein for producing antibodi.

Abstract

Pregnancy-associated glycoprotein (PAG) structurally related to aspartic protease, expressed in the outer epithelial cell layer (trophectoderm) of ungulate placenta. Ovine PAG (ovPAG) synthesized by mono- and binucleic trophoblast before complete implantation at Day 14-15. Of this, ovPAG could be used as a marker for early pregnancy. The objective of study was to extract and isolate PAG from placenta of Garut Sheep collected at term and to characterize their molecular weight. The procedures included extraction of protein at neutral pH (cotyledon was thawed, minced, added PBS, blended and centrifuged), acidic (H3PO41M, pH 4,5; centrifuged) and ammonium sulfate (40% and 80% (NH4)SO4, centrifuged) precipitation; gel filtration (Sephadex-G75), anion exchange chromatography (DEAE- cellulose). Cotyledon extract was subjected to Sephadex-G75 and DEAE cellulose, and their fractions were measured their absorbances. Absorbances of Sephadex-G75 and DEAE fractions at peak were assayed for protein concentration (Bichinconinic protein assay). Continuously, these fractions were subjected to monogel SDS-PAGE and stained by Commassie Brilliant Blue. It was four different molecular weights isolating from cotyledon of Garut Sheep, namely 68.8, 36.04, 32.39 and 12.18  kDa. However, after chromatography anion exchange (DEAE-cellulose), only  three bands exist, those were  71,67;  33,64 and 30,86 kDa.

Abstract

Penelitian ini bertujuan untuk mempelajari efektivitas catatan Test day dengan model regresi tetap untuk evaluasi genetic produksi susu pada sapi perah berdasarkan laktasi satu dan dua. Data produksi susu berasal dari sapi perah Frisian Holstein periode laktasi satu dan dua dari tahun 1989?2000 di PT. Taurus Dairy Farm Sukabumi. Catatan Test day sebanyak 7503 buah berasal dari 456 ekor sapi betina, 40 pejantan dan 342 ekor induk. Model yang digunakan adalah Model Regresi Tetap, varian komponen diduga dengan Animal Model dengan Restricted Maximum Likelihood (REML) dan Nilai Pemuliaan dengan Best Linier Unbiased Prediction (BLUP). Hasil analisis menunjukkan hari test ke-35 (TD2) merupakan puncak produksi. Pengaruh musim terhadap produksi susu Test day mempunyai pola yang kurang jelas. Ragam genetik aditif pada laktasi dua menurun sejalan dengan penambahan catatan Test day sampai dengan Test day ke-3, setelah itu meningkat sampai akhir laktasi. Dugaan nilai heritabilitas mengikuti pola yang sama dengan ragam genetik. Evaluasi genetic berdasarkan laktasi satu penuh yang ditambah dengan satu catatan Test day pada laktasi dua sudah cukup untuk mengevaluasi seluruh ternak, sedangkan untuk mengevaluasi pejantan, evaluasi harus diperpanjang sampai 3 catatan Test day pada laktasi dua.

Abstract

Genetic variation is a major concern in animal genetic resources conservation program. This study aimed to analyze genetic variation and phylogeography of eight Indonesian swamp-buffalo populations based on cytochrome b gene marker. A total of 78 DNA fragment samples originating from eight Indonesian swamp-buffalo populations were used in this study, namely Bombana Island, Bombana mainland, Kolaka, Konawe, North Toraja, West Nusa Tenggara, Banten, and Aceh with 11, 10, 13, 14, 10, 10, 5, and 5 samples, respectively. The cytochrome b gene sequence and genetic variation parameters were analyzed in MEGA software (ver 6), and DnaSP software (ver 5.10.01). The results of this study showed that all DNA-fragment samples were successfully amplified by PCR technique with the size target (906 bp). Based on the distribution of all samples, it was found 9 polymorphic sites, and 10 haplotypes with the haplotype diversities were 0.6590. The average of genetic distances between populations ranged from 0.0000-0.002. They were grouped into two main clusters. The first cluster consisted of Aceh, North Toraja, West Nusa Tenggara, Banten, Kolaka, and Konawe populations, meanwhile, the second cluster consisted of Bombana Island, Bombana mainland, Kolaka, and Konawe populations. The results of the study were concluded that eight Indonesian local swamp-buffalo populations were grouped into two main clusters where Bombana Island and Bombana mainland populations were specific breeds because they were only found in the second cluster and also had specific nucleotides sites on the 57 nucleotides which C base changed to T. The results of this study were useful in formulating the program of conservation and utilization of Indonesian buffalo genetic resources, especially in the buffalo population with specific breeds.

Abstract

The body weight records of 1221 heifers were used in this study collected from PT Taurus DairyFarm Sukabumi from year 2001 until 2011. The records that could be used for analysis were 373 out of1221 heifers, having completed data from birth to first mating period. Three different models i.e,Logistic, Gompertz, and von Bertalanffy were performed to analyze the growth rate of heifers. Theresults showed that the three models had different accuracy and heavily depend on age, environment andduration of recording. The body weights of sexual maturity and on certain ages were affected by theduration of recording. The Gompertz model was performed as the simpliest model in form ofcalculation. On the other hand, the Logistic was more difficult to calculate. All models indicated highaccuracy with the determination coefficient (R2) more than 90%. Based on the comparison, theGompertz and Logistic model are recommended for predicting the growth rate of heifers from birth tosexual maturity.
