“…Peak progesterone levels (0.7–2.0 ng/ml) during early pregnancy were reported in blood plasma of river‐type buffaloes in Sri Lanka (Perera et al. 1981) and swamp‐type buffaloes in Thailand and Malaysia (Kamonpatana et al. 1981; Jainudeen et al.…”

Pregnancy-associated glycoprotein (PAG) concentrations were measured in buffalo cows starting from day 28 after breeding. Oestrus was synchronized in 10 buffaloes using two injections of 25 mg prostraglandin (PG)F(2alpha) (Lutalyse) at a 11-day interval. Blood sampling was conducted nearly twice weekly. Results indicated that plasma PAG concentrations in non-pregnant buffaloes were low (<0.20 ng/ml) during the whole experimental period (day 28 to 103), while in pregnant animals plasma PAG levels increased from day 28 (4.48 +/- 0.92 ng/ml) until day 41 (27.27 +/- 6.74 ng/ml), remaining high (20.71 +/- 9.20 ng/ml) until day 103. Progesterone levels were significantly (p < 0.0001) higher in pregnant (3.51-4.80 ng/ml) than in non-pregnant buffaloes (0.28-1.52 ng/ml). A significant difference (p < 0.0001) in plasma PAG concentrations between pregnant and non-pregnant animals starting at day 28 after breeding suggests that PAG-radioimmunoassay could be suitable for pregnancy diagnosis in buffaloes during this period. In conclusion, PAG test offers the advantages that it requires a single plasma sample for early pregnancy diagnosis as well as the accuracy of the test for the detection of pregnancy as early as day 28.

“…Plasma progesterone concentration can be used in the selection of non-pregnant buffaloes. Plasma progesterone levels on day 10 offer an important indicator, with progesterone levels elevated in pregnant animals, while remaining low in non-pregnant animals (Kamonpatana et al, 1981). The progesterone test is particularly useful with buffalo as oestrous may be difficult to determine (Dobson and Kamonpatana, 1986).…”

“…All candidate recipient animals were subjected to fertility diagnosis by plasma progesterone radioimmunoassay (Kamonpatana et al, 1981) to determine the non-return to oestrous recipients and to predict whether the transferable embryos would be conceived (Supplementary Material S1). They were also assayed for progesterone profiles in plasma every 10 days.…”

The world's first cloned swamp buffalo (Bubalus bubalis) derived from adult ear skin fibroblast has been reported. Donor fibroblast cells were produced from biopsies taken from adult male ear skin and in vitro matured oocytes obtained from a slaughterhouse were used as cytoplasts. A total of 39 blastocysts and 19 morulae fresh embryos were transferred into 12 recipient buffaloes. Progesterone assays indicated establishment of pregnancy in 10 of the 12 buffaloes (83.3%) after 45 days, with six animals still pregnant at 3 months. One recipient maintained pregnancy to term and naturally delivered a 40 kg male calf after 326 days of gestation. DNA analysis showed that the cloned calf was genetically identical to the donor cells. Genotype analyses, using 12 buffalo microsatellite markers, confirmed that the cloned calf was derived from the donor cell lines. In conclusion, the present study reports, for the first time, the establishment of pregnancy and birth of the first cloned Thai swamp buffalo derived from adult ear skin fibroblast cells.
