A study was carried out to compare the efficiency of vaginal electrical impedance with serum progesterone profile, cytological examination and clinical findings. Vaginal electrical impedance values varied at the different stages of the estrous cycle, with the highest value during the transition into estrous and the lowest in diestrus (P < 0.05). There was a negative statistical correlation between serum progesterone values and the impedance values (36%) (P < 0.001). Vaginal electrical impedance was a faster and cheaper method than progesterone assessment. It was more reliable than vaginal cytology and clinical evaluation. In conclusion, a combination of vaginal electrical impedance measurements and progesterone evaluation was a more useful method for determination of the optimal breeding time in bitches.

Toxocariasis is one of the most important parasitic zoonoses affecting human health. The main source of toxocariasis in humans is dog and cat faeces, which are primarily responsible for the contamination of urban areas with Toxocara spp. eggs. In this study, the relationship between dog or/and cat faeces and contamination of sand playgrounds in public parks with Toxocara spp. eggs was investigated. A total of 596 sand and 276 faecal samples (148 dog and 128 cat faeces samples) were collected from 52 public parks in Samsun. Toxocara spp. eggs were identified in 7% of sand samples, 33% of cat faeces samples and 9.5% and dog faeces samples. A positive correlation was found between the presence of faeces and the contamination of sand samples. The incidence of sand contamination was increased 8.3 times if a park contained dog or/and cat faeces, and the incidence was much greater if the faeces were infected with Toxocara spp. ova. Cat faeces had a greater effect on the contamination of sand than did dog faeces. The risk was 12.5 and 27 times greater if a park contained only cat faeces and infected cat faeces, respectively. However, no Toxocara spp. eggs were found in sand samples from parks that contained only dog faeces.

The aim of this study was to determine the short-, mid- and long-term effects of cloprostenol (a synthetic analogue of prostoglandin F2α, PG) and equine chorionic gonadotropin (E) administration on reproductive organs (uterine tissue and ovaries) in female rats. Three different groups, PG, E, and control (C), were created, as well as six subgroups of the PG and E groups. After the treatment procedure, reproductive organs were removed surgically 7, 14, and 21 days after the last injection. Morphometric and histopathological changes in tissues were evaluated. It was shown that PG and E had a moderate proliferative effect on epithelial cells and endometrial glands, especially in the mid-term. It was also observed that, regardless of the time of application, some pathological changes can result from hormone administration.

The aim of this study was to investigate the effect of dietary supplementation of Thymbra spicata L. var. spicata (TS) essential oil (10 or 15 µl · kg−1 live weight (LW)) on growth performance (LW, LW gain, feed intake) and rumen parameters (volatile fatty acids (VFA)) and ammonia levels, and pH) in lambs. The experiment lasted 56 days, including 14 days of adaptation and 42 of experimental period. The TS essential oil was extracted from the leaves harvested at the beginning of plant flowering and contained: 66.86% carvacrol, 12.18% p-cymene, 10.73% γ-terpinene and 2.77% thymol. The addition of TS essential oil to concentrate feed did not affect final LW, LW gain, feed intake or feed conversion ratio (P > 0.05). Molar concentrations (mmol · l−1) of total VFA and acetic (A), butyric (B) and propionic (P) acids, and levels of pH and ammonia-nitrogen (NH3 -N) in rumen fluid were also not affected by TS essential oil inclusion (P > 0.05). However, the proportion of A and (A+B):P ratio in rumen fluid VFA increased linearly (P < 0.01) with increasing TS essential oil doses, whereas the P proportion decreased linearly (P = 0.008). So, it could be suggested that TS essential oil enhanced the concentration of selected VFA in rumen fluid through a positive effect on feed digestion in the rumen. In particular, the linear increase in A and (A+B):P ratio could have enhanced fibrolytic effect in the rumen ecosystem. It was concluded that different doses and longer terms of use of TS essential oil should be further investigated in in vivo studies.
