Abstract

Efisiensi di dalam pemberian makanan ayam petelur dapat tercapai apabila biaya makanan dapat ditekan serendah mungkin, tetapi diperoleh hasil keuntungan yang sebesar-besarnya dengan catatan tidak mengurangi arti dari kesehatan ayam-ayamnya dan menurunkan kualitas telurnya. Biaya makanan ayam di dalam peternakan meliputi 60 persen dari jumlah biaya produksi, sehinggabiaya makanan tersebut besar pengaruhnya terhadap maju mundurnya usaha peternakan ayam (Hadisoeparto 1977).Scott et al.(1976J menyataKan bahwa pada masa pertumbuhan ayam-ayam terutama tipe medium dan tipe berat perlu mendapat pemberian makanan terbatas, karena setiap kelebihan energi dalam tubuh dapat diubah menjadi lemak.

Abstract

The study was aimed to analyze the immunogenicity of GRA1 protein derived from clone bearing GRA1 genes from local isolate of Toxoplasma gondii. Analysis of GRA1 protein translated from cDNA of GRA1 is very essential in prior to expressed the gene. Analysis of GRA1 protein derived from clone bearing GRA1 genes was performed using several bioinformatics software which are available as standalone or online software such as CLC Bio Workbench series, BioEdit, BESTORF, GENSCAN, FGENES, BepiPred 1.0, CTL Epitope Finder and SignalP. Translation coding sequences of GRA1 gene into GRA1 peptide sequences revealed 190 amino acids with molecular mass of GRA1 approximately 20.159 kD and isoelectric point at 4.43. GRA1 protein also identified several antigenic domains with six domains were known as epitopes for CD8+/cytotoxic lymphocyte and seven domain as epitopes for B lymphocyte. However, GRA1 protein was considered as good antigen but less immunogenic.

Abstract

The selection of planktons as live feed for milkfish larvae is a vital tool to meet the natural character as herbivorous species and to fulfill the needs for nutritious food for fish larval growth and survival. Phytoplankton Nannochloropsis sp. and zooplankton rotifer (Brachionus sp.) were two-selected plankton used as the main food source for the milkfish larvae. We performed this study in two times larval culture batch with four observations of tanks as replication. The results showed that we nourished both targeted planktons as larval food, regarding the positive impacts on larval growth (12±1,37 mm of total length, 7±4.89 mg of body weight) and a high survival rate (65.93–77.70%) achieved at the end of the culture period. Plankton diversity analysis presented that Class of rotifer (Monogononta) and Nannochloropsis sp. (Eustigmatophyceae) were both counted as the most dominant plankton group found in the rearing media, showing a decent sign of food supply for fish in rearing water column. The total number of planktons was high and had the tendency to follow the concentration of selected planktons over the culture period in the controlled water.

Abstract

Information of the variability and heritability of quantitative characters on local mungbean germplasm are important for supporting breeding program. A total of 98 local mungbean varieties or accessions were evaluated at Cikeumeuh Experimental Farm,Bogor, during wet season of 2005. The experiment was conducted in a randomized block design with three replications. Each variety was planted in three rows of four meters long. Plant spacing was 40x20 cm, each hill contained two plants. The differences among the varieties were significant for all the characters studied, except for number of seeds per pod and pod length. High yielding varieties were recorded from Demak, Belu, Pati, and Jeneponto. These varieties had a combination of high number of pods per plant, large seed size and early maturity.Seeds weight per plant, pods per plant and seed size had high heritability and expected genetic advance.While the heritability and expected genetic advance for number of branches, pod length, and seeds per pod were all low. Plant height had a high genotypic variance associated with high heritability and high expected genetic advance. Similarly for days to flowering and days to maturity is genotypic in nature with high heritability coupled with a low expected genetic advance for days to flowering and moderate expected genetic advance for days to maturity. Pods per plant, seed size and seed weight per plant had a high genotypic variance associated with high heritability. The genetic advance of these characters predicted that the greatest gain for one generation of selection would be obtained by selection for pods per plant (45.07%), seed size (41.88%) and seed weight per plant (37.03%).

Abstract

After outbreak of Avian Influenza HPAI in chicken in mid 2003 in Indonesia, there was a question whether Avian Influenza HPAI was already presence in animals before the outbreak. A retrospective study was conducted to gain information on the presence of Influenza A virus infection in a range of animal species that could be infected by the virus. A total of 1529 animal sera, from 8 species from 12 different provinces which were stored at the Bbalitvet (Research Institute for Veterinary Science) Serum Bank were tested against matrix antigen of Influenza A using the Agar Gel Immunodiffusion (AGID) test. The results indicated that only 0.6% of animal tested which consisted of 4% of duck sera and 0.4% of pig sera were reacted in the AGID test with weak reaction. Those sera were then tested against Influenza A group viruses using an Enzyme Linked Immunosorbent Assay (ELISA), indicated that Influenza A viruses were not detected in either duck and pig positive sera. Those sera which were also tested by HI test against antigens of HI, H3 and H7, also indicated that none of those sera were reacted. In addition, 134 lung of pigs from an abattoir were collected for virus isolation. The viral isolation on chicken embryonated eggs resulted in 12 samples that contained viruses with agglutinated goose and chicken red blood cells. Identification of viruses isolated was done by agglutination test and ELISA. The results showed that none of those isolates were Influenza Type A virus. This study showed that influenza A virus group infection was not detected in animal species sampled before outbreak of AI H5N1 in 2003 in Indonesia.

Abstract

The study was carried out on August 2000 to July 2001, in 1-ha permanent plot, near Cikaniki Research Station, in Halimun Mountain National Park, West Java.The results shows that, from 1 ha (100 sub plots, each 10x10 m size) studied there were 388 individual numbers of Asplenium nidus L. with some variation on rosette leaves size. The individual numbers of A. nidus were greater at host plant stem with diameter class distribution between 1.3-9.9 cm (45,6%), and than percentages value were decreased in the larger of host plant stem diameter class. Also the individual numbers of A. nidus were greater at under 5 m height position above ground, that is 252 (65,1%).There were no correlation between host plant height (tree trunk height) and A. nidus height position above ground.However there were little linear correlation between rosette leaves size with stem diameter of host plant(Y=1.5586x+317.37 and R =0.0211), and little linear correlation between rosette leaves size with host plant height(Y=2.8241x+304.63, and R =0.0226), but there were no significant increased for both. It was assumed the effects of microclimate(temperature, humidity, light, and rainfall) to distribution of A. nidus as well as horizontal or vertical distribution.

Abstract

Salah satu hama yang menyebabkan penurunan mutu buah-buahan adalah jenis-jenis lalat Dacus. Larva lalat ini umumnya hidup pada bagian tumbuhan yang mempunyai daging lunak, teiutama buah. Larva berasal dari telur yang diletakkan oleh induknya pada permukaan buah dan yang kemudian membor lebih ke dalam ±2- 4 mm (Metcalf & Flint 1962). Selain merusak warna buah, larva Dacus juga mengeluarkan semacam zat yang dapat mengubah susunan jaringan daging buah hingga berwarna lebih tua.lembek dan berasa pahit.Karena kerusakan yang ditimbulkannya, usah memberantas Dacus telah dilakukan dengan berbagai cara, antara lain dengan bahan kimia, dengan pembajakan atau penggenangan di sekitai tanaman (karena pupa Dacus memerlukan tanah untuk perkembangannya),atau dengan pemberantasan secara biologi dengan menggunakan parasit larva Dacus seperti Opius fletcheri (Baltazar 1966) yang terdapat juga di Jawa.Penggunaan metode pemandulan jantan dalam pengendalian populasi Dacus mungkin dapat dipertimbangkan (Lindquist 1969).Salah satu segi yang dianggap sebagai penentu keberhasilan pemandulan jantan ialah cukupnya pengetahuan mengenai bentuk dan struktur luar genitalia lalat ini.Karena itu telah dilakukan penelitian perbandingan yang meliputi morfologi edeagus,testis dan surstilus pada yang jantan serta morfologi ovipositor, indung telur dan spermateka pada yang betina.

Abstract

Although the role of raptors as the top predators in the food chain is important to maintain the balance of an ecosystem, in Indonesia they have rarely been studied.This paper presents the most comprehensive study on the diversity and distribution of raptors with emphasize on Javan Hawk-eagle at Gunung Halimun National Park, the largest remnant forest in Java.The raptor study has been done by field surveys,long watches at selected observation sites and collecting information from previous reports.The results showed that there are 17 raptor species recorded in the area.Furthermore, the Crested Serpent eagle (Spilornis cheelo),Black Eagle (Ictinaetus malayensis), and Javan Hawk-eagle {Spizaetus bartelsi) were recorded in many locations.However,the Black-winged Kite {Elanus caeruleus), Brahminy Kite (Haliastur Indus), Lesser Fish-eagle (Ichthyophaga ichthyaetus),Japanese Sparrowhawk (Accipiter gularis) and the White-bellied sea-eagle (Haliaeetus leucogaster) were observed only in one location. In addition, the Javan Hawk-eagle was recorded at 14 locations namely G. Halimun Utara, G. Buligir Putih, Pasir Cangkuang, G. Malang, West Halimun, G. Bodas, G. Tumpeng, G. Citimur, G. Bengreng, G. Batu, Cadas Mahpar, G. Kempul, G. Kendeng and G. Botol.The number of observed Javan Hawk-eagle individuals at G. Botol was higher than in other locations.
