Pregnancy-associated glycoproteins (PAGs) secreted from conceptus specific trophoblast cells are widely accepted biomarkers of ruminants. Limited information of PAGs in buffalo warrants further investigation for the development of sensitive homologous early pregnancy-specific diagnostic immunoassay. This experiment was thus designed to identify and clone the predominantly expressed early placentome-specific buffalo PAG (buPAG) isoform; to express this PAG isoform and verify its antigenicity by developing antisera and testing immuno-reactivity with recombinant proteins.

The post-thaw fertility of frozen-thawed mammalian spermatozoa is substantially low as compared with that of fresh sperm. Furthermore, the post-thaw fertility of the cryopreserved buffalo sperm has been reported to be poor as compared with that of cattle sperm. Recently, heat shock protein 70 (HSP70) has been found to play a critical role in mammalian fertilization and early embryonic development in boar and cattle.

The present study was undertaken to determine a detailed endocrine profile for prolactin and progesterone during the oestrous cycle in repeat-breeding Murrah buffalo heifers during summer and winter. Hormone concentrations were quantified in blood plasma samples collected over the oestrous cycle in both winter and summer, as well as in samples collected during the summer months to observe circadian rhythmicity. The mean plasma prolactin concentration during the winter months ranged from 3.
