OBJECTIVE
Goat played an important role as source of income for the farmers, also a source of animal protein to support the
national programme on meat self-sufficient. Some favourable characteristics of goat are prolific, the litter is more
than 1 and capability to produce offspring 3 times in 2 years. Un fortunately, due to unoptimal husbandry these
goat cannot express its best reproductive performance (Soeharto, 2008).
Reproductive performance of EG goat so far has not been optimal. This can be seen from long calving interval,
ranges from 9 to 15 months. After partus, is generally decreasing body condition score (BCS) does, conditions that
occur normally but is not expected a drastic reduction (Anonymous, 2006). The low BCS after partum causes a
change in the reproduction performance, such as failure ovulation, extend the periode of estrous postpartum and
calving interval (Widayati et al., 2011). Thus, BCS influence the changes of hormone gonadotropin circulation,
growth as well as the development of the follicle and corpus luteum, and ovarian activity.
Vaginal smear methods were done to obtain an accurate observation of estrous, using epithelial cells taken from
the vaginal wall. Epithelial cells was performed as an accurate parameter in determining the reproductive cycle,
the cells will be directly related to hormones, especially estrogen in the follicular phase and the luteal phase.
Therefore, the study was conducted to determine the reproductive performance of EG goat on body condition
score (BCS) through the observation of vaginal cytology. |
