The water buffalo (Bubalus bubalis) is an important dairy animal on the Indian subcontinent and in Southeast Asian countries. The diversity and differentiation among 12 populations or breeds of buffalo were studied. Data were generated and analyzed from 527 animals belonging to 10 recognized breeds and 2 additional populations of Indian buffalo by using 22 microsatellite loci. Relationships amo...

The objectives of this study were to determine the interval from ovulation to deviation and the diameter of the dominant (DF) and largest subordinate (SF) follicles at deviation in buffalo (Bubalus bubalis) heifers. Two methods of evaluation (observed vs. calculated) were used. FSH and LH profiles encompassing follicle deviation (Experiment 1), and the follicular diameter when the DF acquired o...

BACKGROUND Infection with Toxoplasma gondii in water buffaloes (Bubalus bubalis) is of epidemiological importance because of the risk for transmission to humans. We sought to determine the seroprevalence of T. gondii infection in 339 water buffaloes in Veracruz State, Mexico using the modified agglutination test (MAT, cut off 1:25). Seroprevalence association with general characteristics of buf...

The effect of naloxone on GnRH-induced LH and FSH release was measured in buffaloes in luteal phase of estrous cycle. Animals were administered intravenously, naloxone/saline (50 mg/injection) every 15 min for 3 hr followed by GnRH (100 micrograms). Peripheral plasma LH and FSH concentrations were measured in blood samples collected at 15 min intervals from 1 hr prior to beginning of naloxone/s...

The objective of the study was to evaluate the morphological and functional characteristics of luteal cells isolated from buffalo ovary. Luteal cells exhibited columnar morphology and contact inhibition at the stage of confluence. Protein concentrations increased linearly from Day 3 to Day 7 of culture. DNA concentrations increased from Day 3 to Day 5 and then declined to Day 7 of culture. PGF2...
