Eight Etawah cross bred does were divided into two
groups based on body condition score (BCS). Group I (BSC 2, body
weight 2530 kg; n 4), and Group II (BSC 3, body weight, 3540 kg, n4). All does received intravaginal controlled internal drug
release devices (CIDR) for 10 days, and a prostaglandin F2α at 48 h before CIDR removal. Estrus detection was carried out using
vasectomized buck. Vaginal epithelium was taken to determine estrus cycle. Blood samples were taken every 36 hours, started from
moment of CIDR removal until the end of estrus. The results showed vaginal histological indicated estrus occurred at the hours of 25 to 60
and 30 to 70 post CIDR removal in BCS 2 and 3, respectively. Progesterone peak of BCS 2 and BCS 3 were 0.18±0.31 and
0.48±0.31 ngmL on the hour 0 post CIDR removal. Estradiol 17ß
peak of each group was 53.25±35.08 and 89.91±92.84 pgmL at 48
post CIDR removal. LH surge only occurred on BCS 3 groups, the LH concentrations were 9.9± 9.1; 4.5± 4.0; and 18.2± 9.1 ngmL at
45, 48 and 51 hours post CIDR removal, respectively. It was concluded that the BCS had effects on vaginal histological changes
and LH surge.
