• overt
  • During the 1st oestrus (puberty), the animals received no treatment while on the 2nd day of overt oestrous sign manifestation of the 2nd oestrus, 18 cats were sc treated with proligestone (33 mg/kg) while the remaining 4 cats received normal saline (NS, 0.33 ml/kg), sc. (vin.com)
  • The high estradiol levels produce two important effects: overt estrous behavior and priming of the gonadotropin surge necessary to cause ovulation. (vin.com)
  • oestrus
  • The objective of the study was to estimate the impact of proligestone administration on the suppression of oestrus and on the prevention of recurrence of feline oestrous cycle and its probable unwanted effects. (vin.com)
  • The duration of behavioural alterations indicative of oestrus was recorded in 22 young cats during two consecutive oestrous periods. (vin.com)
  • reproductive
  • To test the hypothesis that induction of BDNF may contribute to changes in hippocampal excitability occurring during the female reproductive cycle, we examined the distribution of BDNF immunoreactivity and changes in CA1 and CA3 electrophysiology across the estrous cycle in rats. (jneurosci.org)
  • The basis of mare reproduction is the estrous cycle, which is the time taken for the development of an egg within an ovarian follicle to the stage that it can be fertilized by a sperm, and for the preparation of the mare's reproductive tract so that fertilization can occur. (equinews.com)
  • Stages
  • At all stages of the cycle the intra-uterine-device-containing horn had a greater wet weight and a correspondingly higher content of cytosolic receptor than its contralateral control horn, the cellular concentration of cytosolic receptor being apparently maintained. (biochemj.org)
  • The four stages of the canine estrous cycle will be reviewed according to these classifications. (lionscourt.org)
  • occur
  • One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. (wikidoc.org)
  • 2 Anestrus is the absence of cycling activity that may occur naturally in periods of short daylight. (vin.com)
  • The patterns of changes in wet weight and content of cytosolic and nuclear receptor that normally occur during the oestrous cycle were not altered by the presence of the device. (biochemj.org)
  • dependent
  • Electrophysiological recordings in hippocampal slices showed robust cycle-dependent differences. (jneurosci.org)
  • We tested the hypothesis that cross-organ sensitization on pelvic-urethra reflex activity caused by uterine capsaicin instillation is estrous cycle dependent. (physiology.org)
  • Differences
  • These results indicate the presence of both sex- and estrous cycle-related differences in the regulation of NT-containing neurons and in the effects of antipsychotic drug administration on the NT system of the rat brain. (aspetjournals.org)
  • effects
  • Ovine uterine gland knock-out model: effects of gland ablation on the estrous cycle. (biomedsearch.com)
  • These studies suggest that hippocampal BDNF levels change across the estrous cycle, accompanied by neurophysiological responses that resemble the effects of BDNF treatment. (jneurosci.org)
  • Principal components were extracted from ratios of line amplitudes and tested for effects of follicle status (dominant v. subordinate) and cycle time point (D1W3, D1W6, D1W2 and D ≥ 17) using multivariate analysis of variance. (pubmedcentralcanada.ca)
  • period
  • The animals were observed for oestrous behaviour for a 12-week period following NS, 1st, 2nd and 3rd proligestone administration. (vin.com)
  • normal
  • Feeding vitamin D to anoestrous ferrets did not result in accelerating the cycle, the ferrets not coming on heat until the normal time. (biologists.org)
  • To truly recognize what is abnormal, one must have an understanding of what is considered normal for the canine estrous cycle. (lionscourt.org)
  • The normal estrous cycle of the canine can be described in several different ways, including behavioral aspects, clinical findings, hormonal values, and cytologic findings of the vaginal epithelium. (lionscourt.org)
  • start
  • The mares generally start cycling when daylight hours become longer, temperatures are higher, and nutrition improves. (equinews.com)
  • female
  • With female ferrets subjected to different degrees of intensity of light irradiation as measured by placing them at different distances from a 1000 W. lamp, the acceleration of the oestrous cycle, generally speaking, was correlated with the degree of intensity. (biologists.org)
  • The practice of breeding requires an understanding of care for the Syrian hamster, knowledge about Syrian hamster variations, a plan selective breeding, scheduling of the female body cycle, and the ability to manage a colony of hamsters. (wikipedia.org)
  • If a female hamster encounters a male when her estrous cycle is not at the point for mating then the two hamsters will be aggressive to each other and could be injured from fighting. (wikipedia.org)
  • While the benefit of spaying decreases with each estrous cycle, some benefit has been demonstrated in female dogs even up to 9 years of age. (wikipedia.org)
  • time
  • We do not have a buck at our farm so it is important for us to be able to recognize when the doe is coming into heat to introduce a buck at the appropriate time or to be able to manipulate the heat cycle if we were to take our does to an outside breeder. (hogcreekhomestead.com)
  • often
  • This part of the estrous cycle may last only one day or so, and the signs may be subtle, so it is often not detected. (vin.com)
  • last
  • The day after the mare goes out of heat is the first day of the cycle and the last day of the following heat is the last day of the cycle. (equinews.com)
