    EFFECT OF FLUSHING AND ESTRUS SYNCHRONIZATION IN POST PARTUM ANESTROUS GOATS
    (KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-09) DEEKSHITH, T.; Dr. R G. BIJURKAR; Prof. M. K. TANDLE; Prof. R.B. DHABALE
    The study was conducted to find out the effect of flushing and hormonal effects upon induction and synchronization of postpartum anoestrus goats in and around Bidar. Thirty does which were about 60 days postpartum were selected and divided in to 5 groups (n=6). All the 5 groups were fed with maize grains (250 gm/doe/day) for 15 days. Group one served as control with only flushing. After 15 days of flushing, 4 treatment groups received CIDR intravaginal device containing Progesterone 0.3gm and left intravaginally for 14 days. At the removal of CIDR after 14 days of treatment, G2 and G4 animals received I/M inj of PGF2α @125µg/doe whereas G3 and G5 received I/M inj of PMSG @ 500IU/doe. Upon exhibition of estrus, 4th and 5th group animals received I/M inj of hCG @ 500IU/doe after natural mating. Estrus inductions were recorded for G1, G2, G3, G4 and G5 as 66.66, 50.00, 83.33, 50.00 and 83.33 % respectively. Conception rate were recorded for G1, G2, G3, G4 and G5 as 100, 33.33, 60, 66.66 and 80 % respectively. Mean ± SE values of onset of estrus were recorded for G1, G2, G3, G4 and G5 as 139.75±19.02, 68.5±4.80, 33.2±2.22, 70.0±1.85 and 32.0±2.82 Hr respectively. Mean ± SE values of duration of estrus were recorded for G1, G2, G3, G4 and G5 as 30.25±1.854, 33.16±2.24, 47.7±2.095, 31.0±0.577 and 36.3±0.86 Hr respectively. Serum was estimated for serum glucose, cholesterol and progesterone. It was concluded that the control group (G1) which received only flushing and group receiving Flushing+ PMSG+ hCG (G5), both have high efficiency in increasing conception rate in postpartum anestrous goats.
