International Conference on Chemical, Environmental and Biological Sciences (ICCEBS'2011) Study on Growth Hormone (GH) Gene of PO Cattle in Indonesia Aloysius D. Corebima, Mariana Rengkuan Syntetic Insemination Main Office Singosari and Syntetic Abstract—PO cattle had been maintained in some cattle breeding Insemination Office Lembang are Technical Implementer Unit institutes, among others BBIB Singosari Malang, and UPA Pasuruan which worked replacement dan production of superior bit of East Java. PO cattle kept in BBIB classified as superior quality, had blood continuously by supplying frozen semen. These been utilized to cow in the UPA; their descendants were distributed superior bull PO, that are cared in BBIB Singosari, in Malang, to farmers. The aim of this research is to identify genetic character of Indonesia, are rated superior by the fact of its fenotip GH gene of PO cattle. DNA isolation conducted by salting out technique, followed by PCR-sequencing procedure. Sequencing characteristic then by frozen semen, those are distributed to results showed that 214 nucleotides read in the 13 samples, 58.4% the breeder. In East Java, BBIB Singosari collaborate with was exactly same to each other, while 41.61% was not same some Local Firm Unit, worked in local cattle proliferation, particularly with respect to tree sampels of UPA. 7 sampels of UPA Alliance Firm Unit Pasuruan. UPA Pasuruan, supply cow PO, and the 3 samples of BBIB still have the same base. Related to the which used as parental stock, and by using frozen semen from 13 samples there were found some conserved sequences even to a BBIB, it is inseminated to febull and the result is bull length of 19 nucleotides, that might be used as significant marker of generation. That is the result, which will be given to bredeer. superior PO beef cattle. That bull generation is used by the bredeer as parental cattle and as meat-producing for people. Keywords— Cattle, gh gene, PCR-sekuencing. As described statements above, it is concluded that BBIB Singosari and UPA Pasuruan East Java, Indonesia have an I. INTRODUCTION important role in case of supplying cattle to fulfil the O Cattle is an offspring of Ongole Cattle, which is necessary of meat of people and also important to preserve the P come to Indonesia from Madras (India) during 1951 to local cattle in Indonesia. Related to the responsibility to 1929 by means of Ongolisation Programme. Compared to supply beef, then these both instances try their best to provide other cattle that is in husbandry of Indonesia, PO Cattel has superior stock parenatal in terms of morfology by bull cattle some special qualities such as relative low care cost for and its regarded as parental selection in the midst the breeder. tolerant to minimal habitat condition [1]- [ 2]-[3]. Research results showed that selection based on morfology The current problem is the decreasing of PO Cattle criteria are less exact because this characteristic is more population over years as reported by “reference [4]” that in influenced by circumstances and it not derived to its descent year 1991 PO population reach to 4,6 millions from 10 [1]. For it, it is needed a characteristic that could be descended millions of PO Cattle in Indonesia and in year 2002 numbered to its descent, that is genetic characteristic. In recent times, 874 thousands or 7,81 percent. This decrease of PO Cattle is there are many researches focused on genetic study as an distrusted for the increasing need of meat of Indonesian [3]. effort to acquire desirable chracteristics, for example The other quite ironic, found in field, is the breeder opting to economic characteristic like growth and production proliferate the import cattle by reasons that meat production is characteristics. Growth characteristic of livestock is led by higher than local cattle in Indonesia. This fact, if left, will growth controller gene. One of the gene than could influence impact to the preservation of Indonesian local cattle as plasma growth is Growth Hormone Gene. nutfah. Base on that problem, then many efforts are carried Growth Hormone is a peptida hormone which is naturally out by Indonesian Government to proliferate and keep local produced by somatotropes, subclass from acidophilic hipofisa cattle. During this day, proliferate and keep process for local cell, located in fore hipofisa gland [5]. Growth hormone is one cattle is doing by Technical Implementer Unit from of important factor in case of growth and development of Husbandry General Directorate, like BBIB, BIB, and BET. animal cell [6]. Growth hormone of Ruminansia is known responsible to Galactopoiesis and Lactation Persistensi [7], so dairy cattle, that is choosen to produce a high quality milk, is A.D. Corebima is with the Department of Biology, Malang State University (phone: +628164294487; fax: +62341-562180; e-mail: expected relinquish a large amount of GH endogen on an [email protected]). average. M. Rengkuan is with the Department of Biology, Manado State University Gene is a part of DNA Segment included all nukleotida, (phone: +6285234261980; @ [email protected]). which are transcribed into mRNA, then will be modified to protein [8]-[9]”. Part of gen, that give code to amino acids and 346 International Conference on Chemical, Environmental and Biological Sciences (ICCEBS'2011) produce protein, is called coding sequence (CDS) and there supernatan is placed in the new tube, added cold ethanol 2250 are also leader segment and trailer segment which flank CDR. µl at the same tube and after that the tube is inverted 25-30 Some genes of Eukaryot characterized discontinuous exon times until white DNA yarn is visible. Then, it is made (protein-coding) and intron (space internal in protein-coding). sentrifus with a speed of 10.000rpm, 40oC during 15 minutes In transcription process, intron part vanish (splicing) so that and supernatan disposed of. Then, it is added 3 ml cold the alteration process can run well [8]. Bovine Growth ethanol 70%. Continued with pellet by wind-dried process Hormone (bGH) is a single peptide with molecular weight 22 using room temperature and then added 100 µl TE buffer, KDa and codifie 191 amino acids [10], and length of placed in an oven 370oC during 10 minutes and kept in - nucleotide sequence 2856 pb [11]. Bovine Growth hormone 200oC temperature. Gene consist of 5 exon and seperated by four intron by [11] C. DNA Amplification of Growth Hormone and located at chromosome 19 [12]. Growth Hormone Gene (GH) is growth hormone-coding Amplification of hormon gene of PO Cattle growth which is produce by somatotropes, in leader pituitary gland hormone gene is made by Polymerase Chain Reaction (PCR) and have some physiology activities. GH Gene has important method. PCR is made by mixing aquadest steril µl and PCR role in case of regulate growth characterization, reproduction, mix 10 µl. The reaction is started by adding 2 µl DNA sample metabolism, lactation, and mammary glands growth [13]-[14]. for each primer. Amplification is executed to PCR tool (gene Along the development of technology in the field of cycler), programmed in accordance with used paired primer. molecular genetics, various researches reported how the The used primer is 5’-CCCACGGGCAAGAATGAGGC-3’ lingkages between GH Gene and milk production and the as forward and 5’-TGAGGAACTGCAGGGGCCCA-3’ as meat of foreign beef [14]-[15]-[16]-[17]. In Indonesia, as reverse, in which each primer can recognize gene sequence reported [1]-[17]-[18] that GH Gene can be a marker in located in 2054-2074 bp for primer and gene sequence located in 2457-2337 bp [18]. Gene cycler is programmed in undertaking a selection of local beef cattle, included PO Cattle o by a study of GH Gene variation. accordance with used primer, that is hot start at 94 C temperature during 1 minute, denaturation at 94oC Based the data above, then the study of GH Gene of PO o Cattle in Indonesia, especially in BBIB Singosari and UPA temperature during 1 minute, annealing at 60 C temperature during 1 minute, extension at 72oC temperature during 1 Pasuruan, which are the prominent institutes of germ o producing of PO Cattle, is needed to identify it genetically. minute and ended with post extention at 72 C temperature That genetically study is expected contribute some beneficial during 5 minutes. The amount of amplification are 30 cycles. things to prepare bull cattle and its regarded as superior D.
