Abstract

This research was conducted to evaluate the performance of female Madura cattle in three districts of Madura Island (Sampang, Pamekasan, and Sumenep), known as breeding areas for purebred Madura cattle. Vital statistics of 1,040 female Madura cattle at 24 and 30 months old in Sampang, Pamekasan, and Sumenep district were measured and analysed. Mean of Body weight, chest girth, body length, and wither height of female Madura cattle at 24 months old were 191.7±17.6 kg, 133±3.0 cm, 124.0±2.1 cm, 115.7±2.9 cm, respectively, and those at 30 months old were 209.4±23.6 kg, 138.2±4.5 cm, 125.7±2.6 cm, 116.7±3.4 cm, respectively. The body weight, chest girth, body length of female Madura cattle at 24 and 30 months old in Pamekasan district (216.6±26.5 kg, 135.2±6.1 cm, 125.4±3.9 cm, and 238.0±28.5 kg, 141.5±6.7 cm, 127.9±3.5 cm, respectively) showed the highest value compared to those in Sampang and Sumenep district. Phenotypic correlation between vital statistics and body weight at 24 and 30 months old ranged between -0.43 to 0.90. Chest girth showed the positive highest correlation with body weight of female Madura cattle at 24 months old (0.24) and at 30 month old (0.90). It indicated that chest girth could be used as estimation parameter for body weight in female Madura cattle.

Abstract

Madura and Bali cattle are two of Indonesian indigenous breeds. One possible method to increase their productivity is through artificial insemination (AI) using frozen semen. This study conducted at the Singosari National Artificial Insemination Center, East Java, Indonesia, to evaluate the semen characteristics of different bull breeds ranging in age from 7 to 10 years and to provide useful recommendations regarding the efficacy of older cattle. A total of 2016 ejaculation data recorded from Indonesian indigenous cattle (Madura and Bali bulls) and Bos taurus bulls (Simmental) were used in this study to analyze semen volume, sperm motility, and sperm concentration. Results revealed differences in semen volume, sperm motility, and sperm concentration among bull breeds (p < 0.05). Simmental bulls have the highest semen volume (p < 0.05) compared with Bali and Madura bulls. Base on sperm motility, Bali bulls showed the highest average value (p < 0.05) compared with Simmental and Madura bulls. Sperm concentration was the highest (p < 0.05) among Bali bulls compared with Simmental and Madura bulls. Another important finding was that the average semen volume, sperm motility, and sperm concentration of older bulls fulfilled the standard criteria established for frozen semen processing. Therefore, it would be possible to improve the performance of these breeds through artificial insemination using frozen semen of Madura and Bali bulls, which can be more widely distributed to farmers to increase their herd productivity. This study also indicates that Indonesian indigenous bulls have superior semen characteristics than Simmental bulls.

Abstract

ABSTRAK Kontribusi ternak lokal dalam memenuhi kebutuhan pangan protein hewani bagi masyarakat Indonesia masih patut diperhitungkan, walau ditenggarai ada penurunan populasinya. Adanya tingkat pemotongan ternak produktif yang tidak seimbang dengan tingkat reproduksinya, ditambah dengan masih berlangsungnya kebijakan impor sapi potong maupun dagingnya, menyebabkan terancamnya ternak sapi lokal menuju kepunahan. Upaya yang harus dilakukan adalah mengembangkan populasinya dengan memperbaiki performans produksi dan reproduksinya. Namun perlu diingat bahwa dalam program perbaikan mutu genetik ternak, program rekording yang dilakukan secara tertib, benar, akurat, dan berkesinambungan, harus mendapat prioritas utama. Untuk memudahkan rekapitulasi dan analisis data, diperlukan software rekording, yang tentunya harus sederhana dan mudah diterapkan di lapang. Dalam Program Rusnas Sapi, telah dirancang software rekording sapi potong (SRS Versi.1.1.) yang dapat digunakan untuk rekapitulasi dan pengolahan data performans produksi dan reproduksinya. Dalam implementasinya di lapang, software tersebut masih terus dikembangkan dan di update sesuai dengan kebutuhan penggunanya. Bersamaan dengan perancangan software rekording sapi, juga telah dipersiapkan disain website sapi potong lokal Indonesia, dimana beberapa tahapan inventarisasi data telah dilakukan. Dengan demikian diharapkan akan terdapat wadah komunikasi bagi para peternak dan terakumulasinya data-base sapi potong lokal di Indonesia. Kata kunci: Rekording, performans, sapi potong lokal, software.   DATABASE RECORDING MODELS OF INDONESIAN  LOCAL BEEF CATTLE PERFORMANCE ABSTRACT The contribution of livestock to meet local needs in food of animal protein for the people of Indonesia should still be calculated, despite the decline in population there. The existence of cutting the level of productive livestock that is not balanced with the reproduction level, and the remains of the policy of import of beef and beef cattle, causing threathened Threatened cattle to the local extinction. Efforts must be done is to develop the population by improving performance production and reproduction. However, keep in mind that the program in the genetic improvement of livestock quality, the program rekording conducted in an orderly, correct, accurate, and sustainable, must get top priority. To facilitate the summary and analysis of the data, the software needed rekording, which of course must be simple and easily applied in the field. Rusnas Cattle in the program, the software has been designed rekording beef cattle (SRS Versi.1.1.) That can be used for reconciliations and data processing performance and production reproduksinya. In the implementation in the field, the software is developed and updated in accordance with the needs of users. Along with the design of the software rekording cows, has also prepared design the website of local beef cattle Indonesia, where several phases of the inventory data has been done. Thus, it is expected there will be for container communications breeders and data-base accumulation of local beef cattle in Indonesia.   Keywords: Recording, performance, local beef cattle, the software

Abstract

INHA gene is a gene that is suggested to have role in reproductive system. Single Nucleotide Polymorphisms (SNPs) of Madura Bulls were identified in this study. Polymerase Chain Reactions (PCR) was used to amplify INHA gene region and MEGA 7 program was utilized to align the amplified region sequences with sequence from Ensembl database. Four SNPs found in INHA and they are located at the first exon. Two SNPs were misssense mutations that causing the substitution of amino acid leucine21 by proline, and amino acid valine63 by methionine and the other two SNPs were synonymous mutation. One of the synonymous SNPs was a novel mutation. Based on those identified SNPs, they could be suggested as potential candidate markers of reproduction traits for Madura bulls. Moreover, through heterozygosity value from the observed bulls, it was indicated that the genotype was varied in population. Therefore a molecular selection program could be designed to determine the Madura superior bull.
