Short Communication: The normal karyotyping result of Indonesian native breed bull qualified for artificial insemination

Abstract

Ciptadi G, Ihsan MN, Nurgiartiningsih VMA, Ardyah IP, Mudawamah M. 2017. Short Communication: The normal karyotyping result of Indonesian native breed bull qualified for artificial insemination. Biodiversitas 18: 1462-1467. Bali and Madura cattle are important native breed in Indonesia, both descendants of wild banteng (Bos javanicus). These breeds are categorized as a small type beef cattle, and are indigenous, well adapted and, have high resistance to diseases. The aims of this research were to analyze dendrograms of these breed and karyotype breeding bull selected for Artificial Insemination (AI). The result showed that the 2n diploid number of chromosome of all cattle was 60 and they were considered normal, based on the number and structure of chromosomes. Fiftyeight acrocentric autosomes and 2 sex chromosome were observed, including a submetacentric X-large chromosome submetacentric and a small Y chromosome. Dendrogram analysis showed that Bali and Madura cattle were closely related and derived more from their ancestor wild banteng than from Java cattle. It is recommended to perform a chromosomal investigation of breeding bulls especially those used for freezing semen production and AI implementation.

A review chromosome analysis comparison of swamp buffalo (Bubalus bubalis) with different phenotypic characters in East Java, Indonesia

“…The results of the karyotyping analysis, when compared with the existing standards, both body and sex chromosomes, also showed normal results [8,9]. Red and white buffalo on Kangean Island and Sumenep, Madura also showed a normal number of chromosomes [9]. Also in previous study have done chromosome analysis of PE and Senduro goats and found that the X-Y chromosomes of the two goat breeds did not differ based on the morphological shape of the chromosomes [11].…”

“…buffaloes with normal blackish grey skin colour, or those with reddish-grey and white skin colour, showed a normal number of chromosomes, as many as 48 chromosomes. The results of the karyotyping analysis, when compared with the existing standards, both body and sex chromosomes, also showed normal results [8,9]. Red and white buffalo on Kangean Island and Sumenep, Madura also showed a normal number of chromosomes [9].…”

A rare chromosomal polymorphism in a Kangayam bull (Bos indicus) of south India

“…3 ), which is comparable to the standard G-banding pattern of Bos indicus cattle viz. Red Kandhari ( Katkade 2005 ), Khillari ( Nakod 2013 ), Malnad Gidda ( Suresh et al 2015 ), Indonesian native bulls ( Ciptadi et al 2017 ) and Nellore cattle ( Amancio et al 2019 ). The GTG-banding results also confirmed that there was no translocation between autosomes and Y-chromosome, as all the autosomes were having the typical G-banding pattern, as those of Iannuzzi and Di Meo (1995) and ISCNDB 2000 ( Cribiu et al 2001 ).…”
