A SURVEY FOR ZOONOTIC AND OTHER GASTROINTESTINAL PARASITES IN PIG IN BALI PROVINCE, INDONESIA

Pigs have potentially to transmit zoonotic gastrointestinal parasite disease both caused by protozoa and worm. The aim of this study was to identify gastrointestinal parasites that were potentially zoonotic in pigs in the province of Bali. A total of 100 fresh feces samples was collected from several pig farms in Bali, from Badung and Tabanan districts, each consisted of 50 samples. Pig feces samples were examined for the presence of eggs worms, cysts and oocysts for protozoa based on the morphology and size. Identification for protozoa and worms used native, sedimentation and sucrose flotation methods. Parameters measured were sex, feed and cage management. The result showed that the characteristic parameters for pigs in both district were generally female. Cage management for raising pigs mostly used group cage. Feed that provided in both district mostly used bran and concentrate. All of 100 pig feces samples that examined positive for parasites. There were 8 types of gastrointestinal parasites that have been identified. Four types of protozoa found were Entamoeba sp. (99%), Balantidium sp. (79%), Eimeria sp. (78%), Blastocystis sp. (69%) and four types of worms were Ascaris sp. (20%), Trichuris sp. (20%), Strongyloides sp. (19%), and Oesophagostomum sp. (8%). All pigs were infected with two or more parasites. The prevalence of parasitic gastrointestinal infections was different for each district, six genera (Entamoeba sp., Balantidium sp., Blastocystis sp., Eimeria sp., Oesophagostomum sp. and Trichuris sp.) were higher found in Tabanan district and the two genera (Ascaris sp. and Strongyloides sp.) were higher in Badung district. Oesophagostomum sp. was only found to infect pigs in Tabanan district. The conclusion is gastrointestinal parasites that found in pigs at Badung and Tabanan district Bali Province mostly have zoonotic potential.

Animals exhibit personality traits in their movement: a case study on location trajectories of primates

Researching individual recognition (IR) is essential to understand the life history and adaptive behavior of social animals. Investigation of personality traits may also provide insights into how social animals distinguish between different individuals. This study investigates IR behavior in Japanese macaques (Macaca fuscata), focusing on one specific trait, which is movement. Using a recently developed tracking system based on Bluetooth® Low Energy beacons, we collected three-dimensional (3D) location data from five Japanese macaques living in a group cage. A non-parametric, neural network-based analysis of the data revealed the existence of personality traits in extremely limited aspects of the movement data (2-min trajectory of 3D location). Our results support the validity of multimodal approaches in studying IR, beyond the typical single-frame face recognition method, both for researchers and animal agents.

TEKNOLOGI TEPAT GUNA MENDUKUNG PENGEMBANGAN SAPI LOKAL PESISIR SUMATERA BARAT

<p>The few last decades the growth of Pesisir Cattle has stagnated due to the decline in the genetic quality. The an proper of culturing management was respected as the main problem in the developing Pesisir Cattle, with the result that the demand elasticity was not comparable with growth. The interoduction of approviate management and technology based on the local resource was considered capable to improve the Pesisir Cattle productivity. This research is try to examine the approvible technology based to local resource to support the development of Pesisir Local Cattle at west Sumatera. The several management and technology innovation can be appled to improve the culturing management, namely: (1) reproductive management by applying artificial Insemination marriage system and use the of superior male; (2) Feed technology through the use of derived process technology such as palm leaf silage depend on local resouces and development of leguminous plants cultivation that it rich in protein; (3) Technology innovation of group cage management such as Grati to breeding as well as to fattening of catle; (4) Integrated farming system according to local culture; (5) Applying of sustainable production system, in which farmers are motivated to work on two forms of livestock business namely fattening and breeding as well; (6) Developing a livestock breeding business system to accelerate the changing pattern of maintenance from an extensive system to an intensive system.</p><p>Keywords: Technology, Pesisir cattle, West Sumatera</p><p> </p><p><strong>Abstrak</strong></p><p>Dalam beberapa dekade terakhir, pertumbuhan sapi pesisir di Sumatera Barat mengalami stagnasi akibat menurunnya kualitas genetik ternak. Manajemen pemeliharaan yang kurang baik merupakan masalah utama dalam pengembangan sapi pesisir sehingga elastisitas permintaan tidak sebanding dengan pertumbuhan. Introduksi manajemen dan teknologi tepat guna berbasis sumber daya lokal dinilai mampu meningkatkan produktivitas sapi pesisir. Tulisan ini membahas teknologi tepat guna berbasis sumber daya lokal mendukung pengembangan sapi lokal pesisir Sumatera Barat. Inovasi manajemen dan teknologi yang dapat diterapkan untuk memperbaiki pola pemeliharaan sapi pesisir antara lain: (1) manajemen reproduksi dengan mengaplikasikan teknologi inseminasi buatan (IB) dan penggunaan pejantan unggul; (2) teknologi pakan dengan memanfaatkan limbah tanaman seperti silase pelepah daun sawit, bergantung pada sumber daya lokal dan pengembangan tanaman leguminosa yang kaya protein; (3) inovasi teknologi dan manajemen pengelolaan kandang kelompok seperti “Kandang Kelompok Grati”, baik untuk tujuan pembibitan maupun penggemukan ternak; (4) pertanian terpadu sesuai dengan budaya setempat; (5) sistem produksi berkelanjutan, dalam hal ini peternak dimotivasi untuk mengembangkan dua bentuk usaha ternak sekaligus, yakni penggemukan dan pembibitan; (6) pemeliharaan ternak dengan sistem gaduhan untuk percepatan perubahan pola pemeliharaan dari ekstensif ke intensif.</p><p>Kata kunci: Teknologi, sapi pesisir, Sumatera Barat.</p>

Genetic parameters for egg production and egg weight of laying hens housed in single and group cages

The present study was conducted to estimate the heritability and genetic correlation of monthly egg production and egg weight of 2 lines White Leghorn hens in single and group cages. A total of 2289 records (line A) and 2596 records (line D) from single cages, 518 and 541 records (for line A and D, respectively) from group cages, were analysed. (Co) variance components of single cage data were analysed using the programme VCE4 applying the REML method and a multiple trait animal model. An EM-algorithm was used to obtain (co) variance components for group cage data. Genetic correlations between single and group cages were analysed using the programme VCE4 based on sire model. Heritability estimates for monthly egg production in single cages ranged from 0.08 to 0.44 (line A); 0.04 to 0.43 (line D) and those for group cages were 0.02 to 0.42 (line A); 0.02 to 0.19 (line D). Egg weight was highly heritable for single and group cages (heritability = 0.25 to 0.54). The genetic correlations between monthly and cumulative egg production were 0.25 to 0.95 (line A); 0.26 to 0.86 (line D) for single cage and 0.24 to 0.84 (line A); 0.26 to 0.96 (line D) for group cage. Cumulative egg production in single cage were highly correlated with those of group cages (0.89 and 0.63, respectively for line A and line D). Single cage records gave higher estimates of genetic parameter than group records. However, the trend of estimates is almost the same. High genetic correlations were found between single- and group cages in most of the production periods.
