The objective was to quantify and compare cow cervical morphology on oestrus vs. non-oestrus daysusing a new farm technology. The cervical tissues were videotaped using a cervixscope involving newcamera equipment in four Holstein cows on multiple oestrus and non-oestrus days to score tissue morphology as altered by oestrus. The non-oestrous days were in diestrus phases. The videotaped records w...

The behavioural assays were carried out in a Y-maze wherein intact, castrated and testosterone-treated male mice were exposed to oestrus and non-oestrus urine samples. The intact male mice investigated more frequently and spent more time in the Y-maze arm with oestrus urine than in that with non-oestrus urine. In contrast, the castrated mice were not attracted to oestrus urine, whereas testoste...

Pregnancy prevention raises much concern to many pet owners. Female cats usually show undesirable behaviour during oestrus. Nowadays, researchers try to explore the reliable and effective ways to prevent oestrus signs in queens. The results of their studies prove that hormone therapy is probably one of the most reliable methods for this purpose. The aim of our study was to compare the effect of...

Fladioimmunoassay technique was used to determine the concentrations of progesterone in serum, fore-milk and saliva of 40 Nili-Ravi buffaloes during pro-oestrus, oestrus, met-oestrus and di-oestrus. Progesterone concentrations during oestrus were uniformly lower in all experimental body fluids; the highest concentrations were found during the mid luteal phase. Although the hormonal trend was si...

Fifteen nulliparous and nine multiparous Serrana goats were used, through two successive oestrous cycles, in order to characterize their ovulation time with regard to the number of ovulations after induced and natural oestrus during the breeding season. The onset of oestrus was detected by the amount of vasectomized bucks after oestrus synchronization with prostaglandin, given 10 days apart, an...

The present study was conducted to see the effect of non-specific genital infections and ovulatory disturbances on clinical signs of oestrusnamely oestrus duration, tonicity of uterus, relaxation of cervix and persistence of follicle. The mean values of oestrus duration, tonicity of uterus and relaxation of cervix varied significantly (P

This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the anoestrus season. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; i...

Buffalo reproduction is considerably affected by late maturity, poor oestrus symptoms and long postpartum periods. This study was undertaken to evaluate the efficiency of Eazi Breed controlled internal drug release (CIDR), an intravaginal progesterone-releasing device, in relation to oestrus and fertility. Five hundred true anoestrus buffalo cows, in the age group 4-6 years in 10 villages of Dh...

oestrus ovis is an economically important parasite of small ruminants and a zoonotic parasite with many reports of ophthalmomyiasis in human from iran and other countries. the aim of the peresent studywas the isolation and identification of excretory-secretory (es) and somatic (s) antigens of o. ovis second and third stage larvae (l2, l3) collected from arabi sheep breeds located in southwest o...

KŘIVÁNEK, I.: Impedance pattern of vaginal and vestibular mucosa in cyclic goats. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 4, pp. 109–114 The changes of vaginal and vestibular impedance during the oestrous cycle in goats were examined. The onset of oestrus was teased with a buck once a day during the experiment. Impedance was measured by a four-terminal method. The vaginal imp...
