Estrous Cycle Manipulation in Dogs
Veterinary Clinics of North America: Small Animal Practice, 2018Since 1939, scientists have studied estrous cycle manipulation in dogs resulting in more articles published in this field that any other area of canine reproduction. Estrous cycle manipulation in dogs must be safe and reliable. Dopamine agonists, gonadotropin-releasing hormone agonists, and gonadotropins are hormones that have been used for estrus ...

The estrous cycle in coyotes (Canis latrans) is characterized by a long proestrus (2-3 months). Vaginal smear patterns associated with proestrus, estrus, and metestrus are described. Data from 41 adults indicated estrus begins about 13 March and persists for 10 days.

The golden hamster Mesocricetus auratus was described as a new species and originally named Cricetus auratus by Waterhouse (1839). Laboratory colonies of the golden hamster both in Europe and America originate from a single capture from the wild by Mr. I.

Unusual and abnormal canine estrous cycles
Theriogenology, 2007Preovulatory serum progesterone concentrations are used to estimate the day of LH peak (day 0), not only to accurately time insemination and predict parturition, but to identify abnormal or unusual estrous cycles due to ovarian dysfunction. Early identification of these disorders is of therapeutic and economic importance.

GnRH Secretion throughout the Ovine Estrous Cycle
Neuroendocrinology, 1987In order to define the patterns of gonadotropin-releasing hormone (GnRH) secretion during the estrous cycle of the sheep we sampled hypophysial portal blood from conscious animals on day 1 of the cycle (n = 1), during the luteal phase (n = 8), during the follicular phase (n = 6) and during the preovulatory luteinizing hormone (LH) surge (n = 6). At the

Lipoproteins during the estrous cycle in swine
Metabolism, 2004The purpose of this study was to examine lipoprotein values at high versus low 17beta-estradiol (E2) concentrations in Yucatan miniature swine. Estrous cycles were measured by heat checking the female on a daily basis using a boar. All swine were fed a 1,050-g low-fat, standard chow diet (8% kcal from fat) once per day.

Estrous Cycle and Ovulation in the Mare
Journal of the American Veterinary Medical Association, 1972SUMMARY Length of estrous cycle and ovarian activity in the nonpregnant mare is related to season of the year and should not be characterized independently of season. Studies at the University of California have indicated that 75 to 85% of mares develop signs of estrus and ovulate from April through October, but these responses to endocrine activity ...

Urination patterns and estrous cycling in mice
Behavioral and Neural Biology, 1979Changes in urination behavior in female C3M/Me-Mg self chocolate house mice were investigated in relation to the estrous cycle. The number of urine spots deposited on filter paper, and visualized under ultraviolet light, was found to be significantly higher during the proestrous and estrous stages of the cycle but showed a dramatic decline following ...

Apoptosis in the Estrous and Menstrual Cycles
Journal of Mammary Gland Biology and Neoplasia, 1999In the absence of pregnancy, the adult mammary gland is subjected to cyclic fluctuations of hormonal stimulation that constitute the estrous and menstrual cycles. The mammary epithelium responds to these systemic hormonal changes by regional proliferation, differentiation and cell death by apoptosis.
