Koonjaenak S. 2006. Semen and Sperm Characteristics of Swamp Buffalo (Bubalus bubalis) Bulls for Artificial Insemination in Thailand, in Relation to Season. Doctoral thesis. ISSN 1652-6880, ISBN 91-576-7263-6 In this thesis work we tested the hypothesis that tropical climatic conditions affect the quality of fresh and frozen-thawed (FT) spermatozoa from swamp buffalo bulls used for artificial i...

In situ hybridization technique was applied using a tritiated (3H) bovine IFNG cDNA probe to regionally localize the gene on river and swamp buffalo chromosomes. The hybridization signals peaked on the 4q23-->q26 bands in river buffaloes and on the 1p24-->p26 bands in swamp buffaloes. The results are compared to the localization of the same gene in cattle. Possible evolutionary conservation in ...

The karyotype of the tamaraw (Bubalus mindorensis, 2n = 46) was investigated by RBG-banding technique and compared with those of the river and the swamp cytotypes of domestic water buffalo (B. bubalis). The tamaraw karyotype consisted of 6 submetacentric and 16 acrocentric autosome pairs (NAA = 56), and X and Y chromosomes. The RBG-banded karyotype of the three taxa had a high degree of homolog...

The sequence of the ribonuclease from the ancestor of swamp buffalo, river buffalo, and ox, corresponding approximately to Pachyporrux lutidem, an extinct ruminant known from the fossil record, has been reconstructed using the rule of ‘maximum parsimony’. This protein and two sequences that may have been intermediates in the evolution of modern ribonuclease have been constructed in the laborato...

The buffalo (Bubalus bubalis) is an important contributor to milk, meat, power, fuel and leather production in many developing countries. Buffaloes can be categorized into Asian and Mediterranean buffaloes. Asian buffalo includes two subspecies known as Riverine and Swamp types. Riverine (water buffalo) and Swamp buffaloes possess different genetics (50 vs. 48 chromosomes, respectively), morpho...

The water buffalo (Bubalus bubalis) is considered an efficient converter of poor quality forages into high quality milk and meat. This species is ubiquitous, with prevalence though in Asian and Mediterranean countries. From a genetic standpoint, the species is characterized by two main subspecies: river and swamp type. The former to be found predominantly in Mediterranean countries, whereas the...

The natural resistance associated macrophage protein 1 (Nramp1) has been reported to confer resistance or susceptibility to Mycobacterium bovis, Salmonella typhimurium, and Leishmania donovani in the mouse, Mus musculus. A Gly and Asp substitution at position 169 of the mouse Nramp protein is invariably associated with the resistant and susceptible phenotypes, respectively. The present study ai...

DOMESTIC BUFFALOES ARE DIVIDED INTO TWO GROUP BASED ON CYTOGENETIC CHARACTERISTICS AND HABITATS: the "river buffaloes" with 2n = 50 and the "swamp buffaloes", 2n = 48. Nevertheless, their hybrids are viable, fertile and identified by a 2n = 49. In order to have a better characterization of these different cytotypes of buffaloes, and considering that NOR-bearing chromosomes are involved in the r...

The objective of this study was to investigate the effect of carbohydrate source and cottonseed meal level in the concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in swamp buffaloes. Four, 4-yr old rumen fistulated swamp buffaloes were randomly assigned to receive four dietary treatments according to a 2×2 factorial arrangement in a 4×4 Lati...

Swamp Buffalo farming plays an important role in farmers' livelihood and satisfying red meat demand South Kalimantan, Indonesia. The extensive (wetland) swamp buffalo production system (SPS) the semi-intensive dryland (DPS) are two systems. systems have high complexity require integrated sustainability assessment approach to measure contribution level of indicators. This study aimed demonstrate...
