anestrous

(10) The results of another study revealed that neonatal exposure to estrogenic-disrupting compounds such as genistein advanced pubertal onset and induced premature anestrous in female rats.

They have multiple estrus cycles during one part of the year, which is called the ovulatory season; and is followed by an anestrous period for the rest of the year.

This long interval can potentially be manipulated in captivity, especially as agoutis do not exhibit lactational anestrous (Guimaraes et al., 2009; Weir, 1971).

Ovulatory response and luteal function after eCG administration at the end of a progesterone and estradiol based treatment in postpartum anestrous beef cattle.

Anestrous (40%), silent heat (31.4%), calving interval (14.3%) and metritis (14.3%) were noticed as reproductive disorders in dairy animals of dairy farms in Punjab.

However, studies performed on anestrous sheep provided contradictory data.

Estrous synchronization can be managed by different programs including single or combined use of hormones such as progestagens, estrogens, melatonin, PGF2[alpha], PMSG, hCG, GnRH in breeding, transition or anestrous seasons in goats (Alaam, 2005; Titi et al., 2010; Alkan et al., 2012).

The experiments were conducted from mid-April to mid-August, when ewes in Northern Utah are seasonally anestrous. At the time of collection, ewes were determined to be anestrous/acyclic due to the visual lack of active follicular development on the ovaries.
