    ABSTRACT : Studies on anestrum in cattle with special reference to treatment regimen were undertaken at Veterinary hospitals and villages in and around Tirupati. A total of 624 cattle (335 heifers and 289 cows) with a history of not coming to heat were examined. The incidence of anestrum, cystic ovaries, persistent corpus luteum due to uterine Pathology and pregnancy were found to be 93.11, 1.60, 2.73 and 2.56 per cent, respectively. The anestrus cattle were classified into true anestrum (59.90%) and subestrm (40.10%). The incidence of anestrum was 43.08 per cent among crosssbred cows as per the data of Animal Husbandry Department, Chittoor for the year 1998-99 to 2004-05. The mean values of hemoglobin, serum calcium, serum inorganic phosphorus and serum iron profiles were found to be significantly lower in anestrus cattle than in normal cyclic cattle. Among 96 cattle treated with various treatment protocols, the estrus response was found to be markedly better in PMSG (75.00%) group compared to KI (70.83%), mineral mixture (70.83%) and GnRH (66.66%) groups. Interval between treatment and onset of estrus was noticed to be significantly earlier in PMSG group. However, the duration of estrus was longer in cattle treated with PMSG. The intensity of estrus was observed to be better in PMSG, GnRH and mineral mixture groups than in KI group. The first service conception rate and overall conception rate was higher in PMSG group. Synchronization of estrus in 40 subestrus cows with various treatment protocols revealed that the estrus response was observed to be 100 per cent in double PGF2, GnRH-PGF2-GnRH and CIDR protocols except in single PGF2 (90%) protocol. Interval between treatment and onset of estrus was observed to be significantly shorter in GnRH-PGF2- GnRH treatment group. The duration of estrus was also observed to be significantly shorter in single PGF2. The intensity of estrus was noticed to be better in CIDR, double PGF2 and GnRH-PGF2-GnRH groups compared to single PGF2 group. The first service conception rate and overall conception rate was higher in double PGF2 (40 and 70%, respectively) and GnRH-PGF2-GnRH (40 and 70%, respectively) groups than single PGF2 (33.33 and 66.66%, respectively) and CIDR (30 and 40%, respectively) treatment regimens. It is concluded that treatment of true anestrus cattle with GnRH, PMSG and synchronization of subestrus cows with double PGF2 and GnRH-PGF2-GnRH protocols proved to more effective and can be utilized under field conditions to curtail these two reproductive hazards.
