Abstract: The purpose of this study is to investigate the secretion pattern of PGFs originated from the uterus and its correlation with progesterone (P) secretion in Japanese native Shiba-goats. PGFs levels in the plasma samples collected from uterine branch of ovarian vein via silicon catheter which had been inserted into the inosculation point of uterine and ovarian branches of the ovarian vein, and P levels in the peripheral plasma samples were determined by RIA. Four female Shiba-goats were used in the present experiment (Table 1).
As shown in Figs. 1-3, PGFs levels in 3 animals with normal estrous cycle began to increase around Day 12 and formed the peak (3.5ng/ml, 14.5ng/ml, 3.3ng/ml) on Day 16-17. Thereafter, PGFs levels decreased and returned to the basal level 24h before the expected next estrus. On the other hand, P levels began to decrease around Day 14 and showed rapid decrease on Day 15. The lowest levels were seen on Day 17-18 (Figs. 2 & 3). In one animal in which no corpus luteum was confirmed at the time of catheterization, both PGFs and P levels were maintained low (Fig. 4). From these results, it was concluded that the increase in the PGFs levels in uterine branch of the ovarian vein preceded the luteolysis in Shiba-goats as known in many other domestic and experi-mental animals. |
