Influence of body condition score on the metabolic and reproductive status of adult female Kacang goats

This study aimed to determine the influence of body condition score (BCS) on the metabolic and reproductive status of adult female Kacang goats (Capra hircus). Twenty-three local doe goats aged 3-6 years, which were not pregnant and had BCS ranging from 1-3 on a scale of 1-5, were studied. Blood samples were collected before slaughtering for biochemical analyses. After the goats were killed, the ovaries were collected for follicle and corpus luteum (CL) examination. Ovarian follicular fluid was aspirated for biochemical analyses. Most blood biochemistry parameters of the goats with BCS 1-3 did not show significant differences (P>0.05). The ovaries with BCS 1 were acyclic; whereas the ovaries with BCSs 2 and 3 were cyclic. The ovarian follicular fluid concentrations of glucose, Ca, and Mg in the goats with BCS 1 were significantly lower than those of the goats with BCSs 2 and 3. The levels of TP, ALB, and cholesterol in the ovarian follicular fluid were significantly correlated with the blood results (P<0.05). In conclusion, Kacang goats with poor body conditions showed ovarian dysfunction. The levels of TP, ALB, and cholesterol in follicular fluid were related to the blood metabolite levels.
