Abstract

Penelitian ini bertujuan untuk mengetahui keanekaragaman spesies dan mengetahui peranan ordo Rodentia di TPA Jatibarang Semarang. Penelitian dilakukan dengan menggunakan metode perangkap kurungan (trapping) dan peranan ordo Rodentia diketahui dari analisis makanan dalam lambung. Penelitian dilakukan pada bulan September-Oktober 2014. Hasil penelitian menemukan sebanyak enam spesies Rodentia terdiri dari celurut rumah (Suncus murinus), tikus riol (Riol norvegicus), mencit rumah (Mus musculus), tikus rumah (Rattus rattus), tikus wirok (Bandicota indica) dan tikus sawah (Rattus argentiventer). Indeks keanekaragaman spesies rendah (H’=0,5-0,65). Analisis lambung menujukkan bahwa ada empat jenis makanan ordo Rodentia terdiri atas bahan organik, biji-bijian, serangga, dan lain-lain yang tidak teridentifikasi. Berdasarkan hasil penelitian dapat disimpulkan bahwa tingkat keanekaragaman spesies Rodentia di TPA Jatibarang Semarang tergolong rendah. Peranan ordo Rodentia berperan sebagai detritivor, granivor, dan insektivor.This purpose of this research was to identify the species biodiversity and to find the role of Rodentia in TPA Jatibarang Semarang. This research was conducted using trap method and the stomach of the captured animals was analyzed to determine their role. This research period was September-October 2014. The research found six species of Rodentia, namely house shrew (Suncus murinus), riol rat (Rattus norvegicus), house mouse (Mus musculus), house rat (Rattus rattus), bandicoot rat (Bandicota indica) and field mouse (Rattus argentiventer). The diversity index is relatively low (H’=0.5-0.65). Stomach analysis showed that there were four kind Rodentia diet and were dominated by material organic, seeds, insects, and other unidentified material. It was concluded that the level of diversity spesies Rodentia in TPA Jatibarang Semarang is low. The species in ordo Rodentia has role as detritivore, granivore, and insectivore.

Abstract

Scientist working in international livestock research are expected to be familiar with an interdisciplinary systems approach, and to work in multidisciplinary teams. The argument for this approach is that (1) discipline specialists are not equipped to understand the relationships between the components they focus on and the systems as a whole, (2) if the specialist operates in isolation from the other discipline, he/she is operating in isolation from the system and so the results may be irrelevant or, if applied, actually have a deleterious effect on the systems, (3) therefore, the specialist must understand the system through a  systems approach, a systems person, or the activities of a team. Applicants hoping to work in international livestock research are expected to have had project experience in the tropics, where the environment, culture, facilities and infrastructure  may be very different from that in Northern Europe. The purpose of this course is to familiarize student with the  multidisciplinary or interdisciplinary systems approach and to prepare them for their field projects in the tropics.

Abstract

The success (or failure) of a breeding centre can be assessed through the genetic trend of trait(s) included in the breeding objective and the inbreeding trend.  Through continuous genetic evaluation and structured mating program, positive genetic trend while maintaining inbreeding on the reasonable level will be achieved.  Inbreeding level of a population is an important aspect in animal breeding as this may lead to a deteriorating phenomenon called inbreeding depression.  This information will guide the animal breeder on how the mating system of their animals will be designed.  Inbreeding level of a dairy cow population generally is maintained to be less than 10%.  The trend of additive genetic (breeding value) and inbreeding of dairy cattle population in Baturraden Dairy Cattle Breeding Centre (Balai Besar Pembibitan Ternak Unggul Sapi Perah, BBPTU) was examined.  The pedigree data consisted of 450 animals and 861 records were analyzed.  The study included two traits namely milk yield (MY) and calving interval (CI).  The pedigree data were collected from 1977 to 1990. The breeding value (EBV) of animals was estimated using DMU computer package applying repeatability animal model and the coefficient of inbreeding was computed with SECATEURS.  The study showed zero inbreeding level of the population based on the pedigree available without any single inbred animal.  The population showed no genetic progress over years during the period of 1977-1990 based on linear regression of EBVs on the year of birth.  This indicated that during the period of 1977 and 1990 the genetic improvement program in BBPTU was unsuccessful.  The inbreeding level of zero could mean that the designed mating system was successful.  However, no genetic progress and no inbreeding trend could mean that no selection program has been introduced in the breeding centre.

Abstract

A data set of dairy cattle production and reproduction taken from Baturraden Dairy Cattle Breeding Centre (Balai Besar Pembibitan Ternak Unggul; BBPTU) was used in the study.  The data included were 180 records of milk production collected from first, second and third lactation.  The  objectives of the study were : (1) to estimate heritability and repeatability of the milk production, (2) to compute accuracy, response and effectiveness of individual selection on different selection methods and intensities, (3) to study the best lactation period for selection in dairy cattle. Some conclusion can be drawn: (1) the estimated repeatability of milk production was considered low, the opposite was true for heritability estimate, (2) the selection response and its effectiveness increased when the number of animals maintained in the population decreased, (3) the selection accuracy increased along with the increased of number of record included, (4) the highest selection accuracy was obtained from individual selection with three records whilst the family selection resulted in the lowest selection accuracy.  It was also concluded that selection in dairy cattle can be done as early as the first lactation and the accuracy will be increased if combined with the information from relatives.

Abstract

Abstract.  This research aimed to evaluate the effectiveness of H5N1 Avian Influenza vaccination in different duck breeds and to assess the magnitude of maternal antibody titer transferred from the vaccinated hen to the eggs and off ducklings as a protector agent against H5N1. Experimental research was conducted on 16 male and 48 female mallards and 16 male and 48 female Muscovy ducks aged 16 week old. The study showed that the vaccination was 83.33 % successful in Muscovy ducks and 100% in in mallards. Result of variance analysis demonstrated that breed and sex did not significantly affected AI antibody titer. AI maternal antibody transferred from Muscovy hens to egg yolks and to off springs was 66.37% and 39.51%, respectively. Female Mallards transferred higher antibody to egg yolks than to off springs (96.40% versus 63.18%, respectively. Antibody titer against AI vaccination was determined through ELISA. This study concluded that AI H5N1 vaccination increased antibody titer in ducks which is transferrable to the eggs produced and ducklings. Key words: Vaccination, H5N1 virus, antibody titer, egg yolk, ducklings Abstrak. Penelitian ini bertujuan untuk mengevaluasi efektifitas vaksinasi avian influenza H5N1 yang dilakukan pada bangsa itik yang berbeda. Penelitian juga bertujuan untuk mengetahui besarnya transfer maternal titer antibody dari induk yang divaksinasi ke  telur dan anak itik yang dihasilkan untuk perlidungan terhadap infeksi virus H5N1.  Penelitian dilakukan secara eksperimental dengan materi  menggunakan itik yang terdiri dari itik Tegal jantan 16 ekor dan betina 48 ekor serta entok jantan 16 ekor dan betina 48 ekor umur 16 minggu.  Hasil vaksinasi  menunjukkan keberhasilan vaksinasi sebesar 83.33% pada entok dan pada itik 100%. Hasil analisis variansi  menunjukkan bangsa itik dan jenis kelamin tidak berpengaruh nyata  (P<0.05) terhadap titer antibodi  flu burng (H5N1).  Besarnya transfer maternal antibodi  flu burung dari induk entok  ke kuning telur  sebesar 66,37%, sedangkan pada anaknya 39,51%. Induk itik memberikan antibodi lebih tinggi pada kuning telurnya yaitu sebesar 96,40% dan pada anaknya 63,18%. Kesimpulan dari penelitian ini adalah vaksinasi flu burung H5N1 meningkatkan titer antibodi pada itik yang dapat ditransfer pada telur dan keturunannya. Kata kunci: Vaksinasi, virus H5N1, titer antibodi, kuning telur, anak itik
