“…In female mammals, testosterone is secreted by the ovaries and adrenals and it can promote female sexual behavior (Hafez, 1974;Yılmaz, 1999;González-Flores et al, 2017). Although there was no significant difference the testosterone concentration observed in this study, there were two high concentrations, one in the kidding period and another before the mating season.…”

“…Seasonal anestrus also includes anestrus processes linked to lactation and postpartum (Dellal and Cedden 2002;González-Flores et al, 2017). Indeed, no significant difference was observed in the seasonal anestrus period in terms of the hormonal results obtained in this study.…”

“…Thus, melatonin concentration starts to increase from the beginning of the breeding season and its concentration decreases towards the end of the breeding season (Figure 1). The reproductive photoperiod control patterns are mediated through circadian rhythmic secretions of melatonin by the pineal gland during darkness periods (Alila-Johansson et al, 2001;Fatet et al, 2011;González-Flores et al, 2017). Indeed, the melatonin concentration detected in this study was increased dramatically during the gestation period (the darkest period) and had started decreasing in kidding period and had reached the lowest concentration in the end of the lactation period.…”

“…However, the main environmental factor affecting seasonal reproduction in goats is the photoperiod (Dellal and Cedden, 2002;Fatet et al, 2011). Seasonality is observed in most breeds of goats raised from high latitudes (>35 , and in temperate regions the mating period is observed in the fall and winter seasons (Chemineau et al, 1992;Fatet et al, 2011;González-Flores et al, 2017). Similarly, the breeding season of Angora goats raised in Ankara, Turkey, varies between September and November (Özdemir, 2009).…”

In this research, annual changes of melatonin, gonadotropin-releasing hormone, follicle stimulating hormone, luteinizing hormone, estrogen, testosterone and progesterone were studied on 6 heads of 1.5 years old female Angora goat. To determine hormones concentrations, blood samples were taken from jugular vein of each goat in every month for a year. The blood samples were centrifuged at 4000xg for 5 min. and serum was stored at -20°C until analyses time. Hormones analyses in the serum were performed by enzyme immunoassay (EIA) method. Monthly climatic values and photoperiod were obtained from the Turkish State Meteorological Service and temperature-humidity index was calculated with climatic values. In the study, in order to determine any possible differences in the observed hormones concentrations with respect to months, repeated measures ANOVA analysis was performed. As a result of statistical analysis, there were no significant differences among the months for gonadotropin-releasing hormone, follicle stimulating hormone and testosterone concentration, while significant differences were found among the months for melatonin, luteinizing hormone and progesterone, and estrogen concentration in female Angora goats. According the results of this study, could be concluded that the releases of reproductive hormones examined in female Angora goats was seasonally dependent.

“…It has been shown that the behavior of the female does not change (Gray & Dewsbury, 1973;Kenney et al, 1979). Behavior of females during estrous is normally triggered by the combined action of estrogen and progesterone (González-Flores et al, 2017).…”

The aim of the study was to evaluate the phylogeny and relationships of the root vole Alexandromys oeconomus with the other species of the tribe Microtini, using the comparison of the characteristics of sexual behavior. Thirteen copulatory behavior patterns that form a specific stereotype of the species' mating behavior are used. The results showed the multiple thrusting stereotype of copulation, which includes separate intromissions and a very first mount with intromission, is ending with ejaculation (from 10% to 48%, depending by the investigated population). The number of ejaculations is comparatively big, varying from 4 to 7 (an average of 4.6) and the genital stimulation rate is from 68 to 260 thrusts. The males of the root vole noted active courtship for the female, which is accompanied by singing, waltzing and marking of the substrate. Marking the territory is manifested by rubbing the femoral region on the substrate, in which the secretion of the hip glands is applied to it. Analysis of the distances (or similarities) between species according to patterns of sexual behavior using the method of cluster analysis indicates the proximity of A. oeconomus to species of the genus Alexandromys and a considerable distance from representatives of the genus Microtus (Microtus s.str. and Sumeriomys). Significant interpopulation differences in copulatory behavior of the Central Asian phylogroup are established (54% of all the behavioral traits studied). The transformation of the stereotype of mating in individuals from Beringia phylogroup in comparison with the Central Asian one is particularly significant and reaches 77% of all the behavioral traits. The data obtained by the analysis of the copulatory behavior of the Alexandromys oeconomus support the separation of the species from genus Microtus.
