Chronic cannabinoid exposure during adolescence may negatively impact brain development and alter adult motivation and behavior. We present evidence that treatment with a cannabinoid agonist during adolescence attenuates estrous-mediated expression of c-Fos within the nucleus accumbens of female rats exposed to a male conspecific. Thirty-two female Long-Evans rats were administered either 0.4 m...

to investigate the igg content and its variations in uterine fluid (uf) during the estrous cycle of the cow and to compare them with those of the blood serum (s), six pairs of serum and uf samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from urmia abattoir. the uf samples were collected by gentle scraping of the endometrium using a ...

The social organization of rodent species determines behavioral patterns for both affiliative and agonistic encounters. The neuropeptide oxytocin has been implicated in the mediation of social behavior; however, variability in both neuropeptide expression and social behavior within a single species indicates an additional mediating factor. The purpose of the present comparative study was to inv...

In this study electrical stimulation-induced rotational behavior was used as a behavioral index of mesostriatal dopamine (DA) activity to investigate gender and hormonal influences on the DA system. In female rats we found estrous cycle related variations in electrical stimulation-induced rotational behavior. A constant electrical stimulus produced significantly more turning on the day of estru...

in this study the reproductive organs of adult and apparently healthy female azarbaijan buffaloes werecollected after slaughter from abattoir. through observation of the ovaries, the luteal and follicular phases ofeach buffalo were specified. a total number of 36 oviducts at follicular phase and 36 oviducts at luteal phasewere collected and 3 tissue samples were taken from 3 regions of infundib...

BACKGROUND Prolonged pre-insemination anestrus (i.e. delayed puberty) is a major contributing factor for culling up to 30% of the replacement gilts at large breeding farm units in Vojvodina. It is imperative to determine if these gilts are acyclic (prepubertal) or cyclic, but just fail to exhibit behavioural estrus. Recent investigations demonstrate that treatment with equine chorionic gonadotr...

Males of all polygynous deer species (Cervinae) give conspicuous calls during the reproductive season. The extreme interspecific diversity that characterizes these vocalizations suggests that they play a strong role in species discrimination. However, interbreeding between several species of Cervinae indicates permeable interspecific reproductive barriers. This study examines the contribution o...

The aim of this review is to give insight into the reproduction potential of the Boer goat doe. Assessment of the reproduction traits in the Boer goat doe demonstrates a mean body weight at puberty of between 30.6 and 27.5kg, depending on the dietary energy level. Kids weaned during the natural breeding season (April/May) exhibit oestrus or puberty earlier than those weaned outside the natural ...
