Cryopreservation technique could be used to preserve animal cell, plant or other genetic materials (included semen) in frozen. In this case, the cryopreservation technique is a storageÂ technique that carries out at very low temperature in liquid nitrogen at -196oC. At this temperature, semen does not experience the process of metabolism but still has the ability to live on when used later. Semen that is preserved by cryopreservation technique has unlimited shelf life. This method is more efficient in terms of cost, time, space, and labour than other methods. Cryopreservation techniques can be divided into conventional technique (controlled slow freezing) and rapid freezing technique. Besides cryopreservation of semen, other genetic material from avian that can be cryopreservesed is Primodial Germ Cells (PGC). Balitnak has succesfully isolated the PGC of some Indonesian native chickens. The success of cryopreservation is indicated by not only the high rate of survival, but also the fertility after cryopreservation. Key words: Avian, storage, cryopreservation, semen

Primordial germ cells (PGCs) can be used for producing transgenic chickens and preserving genetic material of avian species. Primordial germ cells are precursor of germline cells that could be made proliferation and differentiation to become spermatogonia in testes or oogonia in ovary. Primordial germ cells has a unique migration path, so that the PGCs can be isolated and collected from embryos and propagated and developed through the culture. This paper describes the isolation, collection, purification, storage and transfer of PGCs-circulation of local chickens in Indonesia. Some amount of PGCs-circulation were collected from Gaok chicken at stage 15 as the safe level using cryoprotectant DMSO and some chicks hatched after transfering the PGCs-circulation to recipient embryo. Thus, this technology would be useful for preservation of Indonesian local chicken. Key words: Local chicken, primordial germ cells, cryopreservation

Primordial germ cells (PGCs) are original cells of spermatogonia in the testes or oogonia in the ovary. PGCs in poultry can be harvested and stored in the liquid nitrogen and can be used for conservation as genetic materials of poultry. The objective of this study was to obtain the optimal rate of temperature reduction on PGCs quality from three different Indonesian native chicken after thawing. Fertile eggs obtained from native chicken were incubated for 56 hours to obtain embryo at stage of 14-16. PGCs were isolated from the blood using modified Nycodenz Gradient Centrifugation technique. There after they were kept in a straw and equilibrated for 15 minutes at 5oC and frozen at the rate of temperature reduction of 0.3, 0.5, and 1oC per minute using embryo freezing machine (FHK Fujihara: ET-1). After the temperature reached -30oC, then they were plunged directly into the liquid nitrogen. Recovery rate and viability of PGCs after freezing and thawing were measured. The results of this study showed that the average recovery rate of PGCs that have been frozen at rate of temperature reduction of 1, 0.5, and 0.3oC per minute were 35.6, 43.9, and 44.9% respectively. However the rate of temperature reduction of 0.5 and 0.3oC per minute did not significantly affect the recovery rate. The average percentage of viability of PGCs that were frozen at the rate of 1, 0.5 and 0.3oC per minute were respectively 62.6, 77.5, and 77.4%. It seems that the viability followed the trend of recovery rates where the 1oC per minute reduction was the lowest quality compared to the other two treatments. It is concluded that the reduction of 0.5 or 0.3oC per minute are considered as the ideal temperature reduction when native chicken PGCs are frozen. Key Words: PGCs, Native Chicken, Conservation

Recent technological developments to produce germ line chimeras with primordial germ cell (PGC) transfer into the recipient embryo provide an opportunity to conserve and retrieval of chicken genetic resources in complete form. The study was conducted to obtain the most effective DMSO percentage to recovery rate and viability of Gaok chicken PGC after freezing which will later be feasible to be transferred. In this study, the eggs of Gaok chicken were incubated for about 2.5 - 3 days to obtain embryos at stages 14 - 16. Blood retrieval was done through the dorsal aorta using micropipettes under microscope. The procedure of PGC isolation of Gaok chicken with centrifugation gradient was using nycodenz as a substance. Commercially available cryoprotectants (dimethyl sulfoxide = DMSO) were used for PGC freezing. Isolated and frozen PGCs of Gaok chicken were diluted with cryoprotectants containing 2.5; 5 and 10% DMSO in fetal bovine serum (FBS). The recovery rate of 2.5; 5 and 10% DMSO concentration were 36.4; 48.2 and 48 % respectively. The viability of PGC after freezing was significantly higher for 5% DMSO compared with 2.5% DMSO (P<0.05), but not different from 10% DMSO. It can be concluded that the concentration DMSO of 5 % was effectve contration in freezing Gaok chicken PGC.

Development and Conservation of Gonadal Primordial Germ Cells for Preservation of Local Chicken in Indonesia Tatan Kostaman; S Sopiyana

One of the ex situ conservation techniques for poultry that recently developed was to collect primordial germ cell (PGC) or gonadal primordial germ cell (gPGC) that isolated from embryo development. Primordial germ cells (PGC) are embryonic cells that migrate to the gonads and form the precursors of gametes. The unique nature and accessibility of PGC during the early development provides an opportunity to manipulate the poultry germplasm, for example by forming germline chimeras. There are some stages that must be done through isolation and collection of PGC from its resources i.e. blastoderm, embryonic circulation blood and gonad. PGC collection originating from the gonads is one of existing PGC resources and technologies. gonadal PGC have advantages compared with other sources, namely (1) A large number of gonadal PGC can be taken from an embryo; and (2) A collection of gonadal PGC can be used in developing management systems of local avian germplasm conservation. This review is intended to describe the usefulness of isolation and collection technology of gonadal PGC as the local poultry germplasm conservation in Indonesia.

Penelitian untuk mengetahui motilitas dan daya hidup spermatozoa kambing Boer pada pengencer trissitrat-fruktosa telah dilaksanakan di Laboratorium Fisiologi Reproduksi, Balai Penelitian Temak, Ciawi-Bogor. Penelitian ini bertujuan untuk mengetahui apakah masih terjadi penurunan kualitas Spermatozoa kambing Boer pada penyimpanan suhu ruangan, karena seperti diketahui semen kambing mudah mengalami kerusakan yang mengakibatkan penurunan kualitas semen, terutama motilitas dan daya hidup spermatozoa. Dua ekor kambing BOW jantan digunakan sebagai sumber semen. Penampungan semen dilakukan sekali dalam seminggu dengan menggunakan vagina buatan. Hasil penelitian menunjukkan bahwa persentase motilitas antara ejakulat 1 dan 2 yang diamati setelah 3 jam pengenceran berbeda nyata (69 vs 67,1%; P0,05). Sementara itu, untuk spermatozoa hidup yang diamati pada 3 dan 6 jam setelah pengenceran tidak berbeda nyata (P>0,05) antara ejakulat 1 dan 2, tetapi tingkat penurunan untuk persentase motilitas dan spermatozoa hidup pada ejakulat 2 memberikan rataan tingkat penurunan yang lebih rendah dibandingkan dengan ejakulat 1 (2,1 vs 4% untuk motilitas dan 0,6 vs 1,8% untuk spermatozoa hidup). Disimpulkan bahwa pengencer Iris-sitrat-fruktosa dapat mempertahankan kualitas semen kambing Boer.

Cemani chicken is an Indonesian native chicken with black hyperpigmentation on feathers, skin, beak, comb, and flesh. Hyperpigmentation in chickens is called Fibromelanosis. Fibromelanosis in Cemani chickens is semi–dominant, producing two genotypes: homozygous (Fm/Fm) and heterozygous (Fm/fm+). Cemani chicken meat’s black color may indicate a higher mineral content than regular chicken meat. The study’s is aims are to detect genotype homozygous (Fm/Fm) and heterozygous (Fm/fm+) mutations and to determine the mineral content of Cemani chickens with homozygous (Fm/Fm) and heterozygous (Fm/fm+) genotypes. In the Cemani chicken population (n = 32), the Fm–specific allele genotype was detected using a Polymerase Chain Reaction–Restriction Fragment Length Polymorphism (PCR–RFLP) and the MluI restriction enzyme. The mineral contents of Cemani chicken tested were Fe, Zn, Mn, and Se. The results showed that homozygous Cemani chickens (Fm/Fm) had higher Fe and Zn mineral content. However, the homozygous (Fm/Fm) and heterozygous (Fm/fm+) Cemani chicken were not different in mineral content of Se and Mn. This study found that different genotypes of Cemani chicken had different mineral compositions. In the future, this analysis supports the selection of chicken strains with high antioxidant levels.
