Aim:
The purpose of this study was to determine the postpartum estrus cycle of guinea pigs (Cavia cobaya) using Anredera cordifolia leaf extract.
Materials And Methods:
Materials used were 8 males and 8 females of C. cobaya with body weight ranged 400-450 g. Mating ratio applied was 1:1. Treatments given were 0, 10, 50 and 90 mg of A. cordifolia leaf extract/head, designated as T0, T1, T2 and T3, respectively. Two females were subjected for each treatment. A. cordifolia leaf extract was administered orally from 10 days prepartum to 10 days postpartum. Observation of mating behavior, vulva morphology, and vaginal smear preparation was done in the afternoon for 10 days subsequence postpartum. Data were analyzed by univariate method and descriptively.
Results:
The results showed that the addition of A. cordifolia leaf extract 50 mg orally could accelerate the time of postpartum estrus based on the average frequency of mating behavior consisting of behavioral approach, allow the buck to sniffing her, mating positions, standing heat, lordosis position, and copulation. During estrus, vulva morphology was red color, had much mucus and no thin membrane covering vagina. There were a lot of superficial cells on vagina.
Conclusion:
The best treatment to accelerate occurring postpartum estrus was the addition of A. cordifolia leaf extract as many as 50 mg/head weight (T2) orally.
