    Alternative remedies used by resource-limited farmers in the treatment and manipulation of the reproductive system of non-descript goats in the Eastern Cape province, South Africa
    (University of Fort Hare, 2014) Rwodzi, Maxwell
    This study was carried out to determine alternative approaches used by resource-limited farmers to enhance fertility and in the treatment of reproduction ailments of goats in Mount Frere area, Eastern Cape Province of South Africa. Furthermore, information on farmer perceptions pertaining to these practices was also gathered. A questionnaire survey was conducted to determine materials used by resource-limited farmers to enhance fertility and treat reproductive ailments. The survey revealed 10 plant species that were commonly used for reproductive health in goats. Elephantorrhizza elephantina (37.1%) and Rhoicissus tomentosa (25.7%) were the most frequently cited plant species. Elephantorrhiza elephantina and R. tomentosa recorded the highest Fidelity Level (FL) values of 92.86% and 75% respectively, for their use in the treatment of reproductive ailments and these were the plants on which further studies were conducted. The study also revealed that farmers had different perceptions on the effectiveness of the traditional medicines. An in-vivo assessment was done to determine efficacy of E. elephantina and R.tomentosa using serum estradiol and progesterone profiles. The highest (P<0.05) serum estradiol and progesterone concentration was observed in animals administered with aqueous extracts of E. elephantina and R. tomentosa mixture while the least (P<0.05) concentrations were observed in the negative control group. Does administered with a mixture of aqueous E. elephantina and R. tomentosa extract had the highest (P<0.05) body weight (65 kg) as well as body condition scores, while the negative control which were administered with distilled water had the least body weights (54 kg) and body condition scores. Does that were administered with a mixture of E.elephantina and R. tomentosa were all pregnant with twins (100%), confirmed by a doppler ultrasound scan.
