Examination of vaginal smears from these individuals indicated that the largest proportion of females were in proestrous (221 individuals, 48%), followed by the estrous (141 individuals, 31%), metestrous (70 individuals, 15%), and anestrous
stage (25 individuals, 6%).
Effect of progesterone and/or estradiol treatments prior to induction of ovulation on subsequent luteal lifespan in anestrous
Effects of estradiol and progesterone on circulating LH and FSH secretion, and ovarian antral follicle growth in anestrous
It can be referred to reducing estrus period, increasing fetal mortality, increasing probability of abortion and anestrous
, reduction in lactation and enhancement of interval between calving and fertility [1,3,10,16].

These fixed-time AI systems work well for the synchronization of estrus/ovulation, and also for the induction of cyclicity in anestrous
Each year these seasonal breeders experience an anestrous
period during which they fail to exhibit ovarian cycles.
Additionally, we noted if a male's testes were regressed or descended, and if females were anestrous

During late summer and early autumn, cows with calves and juveniles generally occupy the northern 'nursery' grounds, whereas large subadults and adults (males and anestrous
females) occupy the 'rocknosing' grounds (Finley, 1990).
The exogenous source of P4 administered in a CIDR enhances plasma concentrations of P4, which increases the frequency of LH pulse and resumes the cyclicity in anestrous
cows after its withdrawal (Stock and Fortune, 1993; Day, 2002; Rhodes et al.
