The study was conducted to evaluate the levels of serum glucose and cholesterol at different time interval i.e, -15D, -7D, 0D, 7D, 12D and on the day of estrus in synchronization protocols in postpartum anestrous Kenguri ewes in non-breeding season. Thirty healthy ewes of 60 days postpartum were selected and divided in to 5 groups, each containing 6 animals (n=6). All the five groups were fed with maize grains (250 gm/ewe/day) for 15 days prior to synchronization protocol as flushing protocol. G-I served as control group with only maize feeding without treatments. After 15 days of Maize feeding, 4 treatment groups received CIDR intravaginal device (0.3 gm of progesterone) left intravaginal for 12 days. After 12 days, during the removal of CIDR, G-II and G-IV animals received I/M inj.PGF2α @125µg /ewe whereas G-III and G-V received I/M inj. PMSG @ 500 IU/ewe. Upon exhibition of estrus and natural mating, G-IV and G-V animals received I/M inj. hCG @500 IU/ewe. In conclusion the blood serum glucose levels in the present study were found to be decreased on the day of estrus whereas the blood serum cholesterol levels were found to be increased on the day of estrus in experimental animals.
