“…Buffalo (Bubalus bubalis) is an economically important dairy animal species in many Asian, African and Mediterranean countries because of its immense potential in agriculture, milk and meat production (Nanda and Nakao, 2003). Poor reproductive efficiency of buffalo, however, is a major hindrance toward implementing planned breeding improvement programs in this species.…”

A buffalo oocyte-specific subtracted cDNA library was constructed to identify exclusively or preferentially oocyte-expressed genes. The library represented an enriched population of transcripts obtained from oocytes of diverse ovarian follicular origin and at different stages of in vitro maturation. A total of 1173 high-quality sequences of oocyte-specific genes were clustered into 645 unique sequences, out of which 65.76% were represented as singlets and 34.26% as contig expressed sequence tags (ESTs; clusters). Analysis of sequences revealed that 498 of these sequences were identified as a known sequence in mammalian species including buffalo, 103 as uncharacterized ESTs and 44 unknown sequences including 1 novel EST, so far not reported in any species. Gene ontology annotation classified these sequences into functional categories of cellular events and biological processes associated with oocyte competence. Expression status of the isolated unknown ESTs confirmed that many of these are expressed in oocytes exclusively and in others preferentially, some in excess of 80-fold greater in comparison with a variety of somatic tissues. The isolated novel EST was detected to be expressed exclusively in oocytes and testicular cells only. To our knowledge, this is the first report giving a detailed transcriptome account of oocyte-expressed genes in buffalo. This study will provide important information on the physiological control of oocyte development, as well as many questions yet to be addressed on the reproductive process of buffalo.

Abstract.Repeat breeding is one of the most important reproductive disorders in buffaloes. Its etiology, however, is not well described. The aim of this study was to show the clinical features of repeat breeding buffaloes referred to infertility camps in the southern region of Nepal. Eighty-five buffaloes mated three times or more without conception were clinically examined. Sixty percent of the buffaloes were heifers. Fifty-nine percent of the buffalo cows with repeat breeding were already 10 months or more after calving. Indications of cervicitis were observed in 25% of the repeat breeders. Buffalo cows 12 months or more after calving and heifers in adequate nutritional condition were treated with either GnRH or PGF2α, and showed a satisfactory conception rate after treatment. Cows within 12 months post partum and heifers at a relatively younger age were treated with a vitamin/ mineral mixture supplement, and this resulted in a moderate conception rate. In conclusion, the major clinical features of repeat breeding buffaloes include a large proportion of heifers, a long interval from calving to treatment, a high incidence of cervicitis, and a high or moderate response to treatment with PGF2α and GnRH or vitamin/mineral mixture. More attention needs to be paid to estrous detection and management of mating with bulls.

“…Swamp buffalo milk has even higher fat (9-15%), protein (7.1%), lactose (4.90%) and ash (0.89%) (Thac, 1979). Buffalo milk is especially important, and priced higher in Italy, for making Mozzarella cheese (Nanda and Nakao, 2003). Buffalo genetic improvement Genetic improvement of large number of buffaloes under different stakeholders in South Asia demands on quality buffalo male germplasm.…”

Buffalo is considered the dairy animal for 21 st century due to its higher adaptability and productivity in the changing climatic conditions. There is a large diversity in the buffalo genetic resources and South Asia is home of high yielding source promising buffalo breed of Murrah and Nail Ravi. South Asia is inhabitant of 151.49 million buffalo populations out of 194.29 million of global populations. Besides, about 79.74 % of Asia and 77.9 % of world buffalo populations are inhabitant in South Asian countries. During the last decade, the world buffalo population has been increased by approximately 1.49% annually. South Asia is currently producing 100.74 million metric tons of buffalo milk which is about 96.05 % of Asia and 93.19 % of world buffalo milk production. The share of buffalo milk is around 51.07% of the total milk production of the South Asia. The contribution of buffalo milk in India, Nepal and Pakistan are 51.2%, 66.6% and 59.5% respectively in total milk production. Among the South Asian countries, maximum milk is produced by India followed by Pakistan, Nepal, Bangladesh, Sri Lanka and Bhutan. The productivity of buffalo has been recorded 410 kg Although most of the buffaloes are non-descript indigenous types and their production potential is not satisfactory. There are different production systems are prevailing such as zero input-low output, low input-medium output and high input-high output. Moreover, selective breeding for buffalo with the same breed under low input-medium output production system and grading up of non-descript buffaloes using improver breed/s under zero input-low output production system has been commonly practiced. The demand of milk has been increasing due to economic solvency and rapid pace of urbanization but most of the countries are deficit in production even it is challenging to meet the * Corresponding author e-mail: nasiddiky.saarc@gmail.com : 10.11.2017: 10.11.

To increase the productivity through genetic improvement of buffaloes could be important thrust areas to obtain projected demand of milk. Productive and reproductive efficiency can only be improved by adopting suitable breeding policies and good management practices. Received
