Pemanfaatan informasi genom untuk eksplorasi struktur genetik dan asosiasinya dengan performan ternak di Indonesia

Abstract

<p class="MDPI17abstract">Currently, livestock development strategies in various countries have made extensive use of molecular technology at the genome level. Genome contains information of the entire DNA within the livestock cells, therefore it is believed that this technology is able to map the relationship between genotypes and phenotypes more precisely. Genome technology describes all genes in the body and how they interact and influence the growth and performance of livestock. Genome information can support every effort for livestock development including breeding, optimizing the feed nutrition efficiency through the use of feed ingredients more efficiently, and improving reproduction performance. In terms of efforts to improve livestock performance in Indonesia, genomic technology can be utilized to increase the accuracy and efficiency of livestock selection programs. The application of genomic technology in Indonesia still encounters many constraints, including lack of confidence on the benefits that can be generated, the high cost, as well as the incomplete recording data of livestock performance. Currently, researchers in Indonesia have started utilizing genome information to explore the genetic structure of livestock and its association with the livestock performance. Support from all stakeholders are needed to minimize the limitations of genome technology application on livestock in Indonesia.<strong></strong></p>

Manajemen Kesehatan Ternak Babi Melalui Pemberdayaan Masyarakat Peternak Babi Skala Rumah Tangga

“…Bagi kebanyakan peternak skala kecil atau rumah tangga, permasalahan ini merupakan masalah sederhana, namun permasalahan manajemen pemeliharaan terutama manajemen reproduksi merupakan permasalahan penting dan utama dalam menentukan keberhasilan usaha peternakan babi. Recording atau pencatatan merupakan faktor penting untuk mengetahui kinerja reproduksi dari setiap individu ternak babi (Sudrajad et al, 2021). Sebagai contoh dalam aspek reproduksi, dengan adanya recording maka akan sangat memudahkan evaluasi terhadap manajemen reproduksi yang sudah diterapkan (Susilawati et al, 2022).…”

GDF9 gene polymorphism and its relation to litter size in East Java Pote goat germplasm

“…Based on the PCR results shown in Figure 2, it is evident that all GDF9 gene samples of Pote goats exhibit clearly visible DNA bands, indicative of proper DNA amplification or separation. According to [16] the purity of the DNA produced during the extraction, the selection of appropriate primers and the PCR conditions are important for good PCR results. The PCR results of the GDF9 gene in Pote goats exhibited targeted amplification of the desired fragment (491 bp) without any amplification of contaminant or unintended fragments.…”

“…Twin births may be affected by hereditary factors transmitted from the parents to their offspring. Productivity of the parent is directly associated with litter size; thus, the larger the litter size, the greater the parent productivity [16]. [18] assert that three factors determine the litter size of goats, namely, the number of eggs produced during lambing and ovulation, fertilization, and conditions during pregnancy, as well as embryo death.…”
