| Summary: | (A-.044 mg/kg BW; B-.088 mg/kg BW; and no altrenogest) over 1, both number of days until ovulation and follicular activity exhibited differences. Number of days until activity, and mean LH concentration were analyzed, no administration of progesterone, in the presence of an age from 2-19y were randomly assigned to three treatments altrenogest (17-Allyl-17phydroxyestra-4,9,1 1-trien-3 -one) between mares treated with altrenogest when compared with blood samples collected via jugular venipuncture using a coefficients of variation were 1.39% and 5.39%, concentration did not show significant difference in values day until ovulation. Treated mares were given altrenogest delaying ovulation. The objective of this experiment was to difference was found due to a period by treatment double-antibody RIA. The intra- and inter-assay effect of altrenogest administration on the three previously effects of progesterone. The possibility exists that elucidate the potential for oral administration of Estrogen from a growing follicle stimulates the preovulatory first day a 35mm follicle was first detected and every other follicular diameter maintenance (P<.05) for mares in for mares in treatment A when compared with the control for the first two days. Beginning on the fifth day after found in either parameter. greater than 48h. Fourteen light horse mares, ranging in initiation of treatment, the mares were bred every other day interaction. Data were analyzed by period to determine mares. Follicular activity also exhibited an increase in mentioned factors. Period I was most representative of a of altrenogest administration. No differences (P>.05) were ovulation demonstrated an increased (P<.05) number of days ovulatory follicle, would sufficiently suppress LH thereby respectively. When number of days to ovulation, follicular size change were also measured to determine possible effects surge of luteinizing hormone (LH) unlike the suppressive the control mares. Pregnancy rates and embryonic vesicle three consecutive estrous cycles. Mares received the to postpone ovulation of a preovulatory follicle (35mm) for transrectal ultrasonography. Control mares were bred on the treatment A when compared with the control mares. Mean LH treatment dose when a >35mm follicle was observed via true response to administration of altrenogest. In period until ovulation. LH was determined during estrus on daily |
