Obstructive upper respiratory tract diseases are an important cause of poor performance in racehorses. Diagnosis of these diseases can be made easily by endoscopic examination. The aim of this study is to emphasize the frequently encountered obstructive respiratory tract diseases in the endoscopic examination of the upper respiratory tract in thoroughbred Arabian and British racehorses and the importance of endoscopic examination in the diagnosis of these diseases. The study material consisted of 72 horses (37 Arabian, 35 British horses) between the ages of 2-7 who had no respiratory complaints at rest, but had low racing and training performance. No pathology was detected in 32 (44.44%) of 72 horses who underwent clinical and endoscopic examination. it was detected that 19 (47.5%) palatal instability, 10 (25%) dorsal displacement of the soft palate (DDSP), 8 (20%) pharyngeal lymphoid hyperplasia, 2 (5%) laryngeal hemiplegia, 1 (2.5%) subepiglottic cyst of the remaining horses. As a result, it should be considered that there may be obstructive respiratory tract problems in horses that have a very good general health status at rest and show low racing and training performance. In addition, clinical examination in these horses should be supported by an upper respiratory tract endoscopic examination.

Zonulin, a well-recognized protein, is influencing the integrity of intercellular connections in the intestines. It has also been evidenced that heat stress (hS) might alter intestinal permeability. In the present retrospective field research the aim was to investigate the gastrointestinal permeability of calves exposed to hS (especially in summer) by determining serum zonulin levels and their relationship to seasonal dissipation among appearently healthy calves. As two different months represented 2 seasons, serum zonulin concentrations in January 2022 (at 20:00 pm 4°C and 08:00 am 10°C) and June 2022 (at 20:00 pm 19°C and 08:00 am 27°C) exhibited significant differences. Inter-group and intra-group comparison showed statistically significant differences (p=0.012) both in seasonal distribution and spatial distribution at different day/night times. When compared between the January and June groups, the mean zonulin levels (ng/mL) at 12 pm and 08:00 am in the January group were 28.04±12.49 vs. 11.55±8.45, respectively (p=0.012). On the other hand at June group the mean zonulin levels at 12 pm and 08.00 am were 58.54±19.16 vs 24.03±9.9, respectively (p=0.012). Obtained results should be cautiously subjected to interpretation, in which hS affect intestinal integrity and seasonal dissipation of circulating zonulin levels should be taken into consideration for intestinal health of calves.

Osteomyelitis is a severe bone disease that is difficult to treat and causes serious socioeconomic problems. This study aimed to examine the bioactivity of hesperidin in an in vivo Staphylococcus aureus-induced osteomyelitis model. Total of 28 male Wistar Albino rats were randomly divided into 4 equal groups (n=7). Groups were designated as Group 1: Control group, Group 2: Sham group, Group 3: Osteomyelitis group, and Group 4: Treatment group (Hesperidin+Osteomyelitis). Unilateral tibial osteomyelitis was induced by administering arachidonic acid and 1×106 CFU-1 bacterial suspension through a hole drilled from the tibial crest. The rats in the treatment group were given hesperidin once a day by oral gavage for 28 days. At the end of the treatment, the effectiveness of the treatment was evaluated radiographically, biochemically, and histopathologically. The mean scores of intraosseous acute inflammation, intraosseous chronic inflammation, periosteal inflammation, and bone necrosis were evaluated histopathologically. The score was 0 in the control group, 0-2 in the sham group, 9-14 in the osteomyelitis group, and 2-6 in the treatment group. The median values of IAI, ICI, PI, BN, and total histopathological scores of the treatment group were significantly lower than the osteomyelitis group. Biochemically, oxidative stress increased significantly in the osteomyelitis model, however, it significantly decreased in the group treated with hesperidin. Nrf-2 translation levels increased by 0.2% in the sham group compared to the control group and decreased by 26% in the osteomyelitis group but increased by 42% in the treatment group compared to the osteomyelitis group. Compared to the control group, NF-kB translation levels increased by 6% and 21% in the sham and osteomyelitis groups, respectively. However, this value decreased by 9% in the treatment group compared to the osteomyelitis group. Radiographically, the combined score reduced by 65% in the treatment group in comparison to the osteomyelitis group. In conclusion, hesperidin showed anti-inflammatory activity by suppressing NF-kB and antioxidant activity by increasing Nrf-2, both of which play a role in inflammatory pathways. In light of all these findings, it can be said that hesperidin can be used as a potential therapeutic or an agent that can contribute to the treatment of osteomyelitis.

In this review, the use of some feed additives in the diets of ruminant animals is discussed. Brief information about the anatomy of the digestive system of ruminants and the metabolism of some nutrients in these animals are presented. In addition, summary information about some feed additives used in animal nutrition is given. Particularly detailed information about pre/probiotics among feed additives is presented, and the effects of S. cerevisiae, known as yeast, are discussed. In ruminant animals, unlike the monogastrics, feed additives, especially pre-and probiotics, are utilized to affect fermentation in the rumen. In addition, it is seen that it is used to increase immunity in pre-ruminants. However, it is obvious that more studies are needed on these issues.

Propolis is a resinous natural product produced by honey bees by mixing collected buds and exudates of plants with bee wax. Bees use propolis to protect themselves against wind and rain by using it to construct and repair hives. Propolis has a wide range of biological effects as it is a mixture of natural substances, and it is widely used for its anti-inflammatory, anti-oxidant, immunomodulatory, and anti-cancer effects. Propolis has been used in traditional medicine since time immemorial. Research studies on the anti-tumor effects of propolis extracts and components such as flavonoids, phenolic acids, and their esters demonstrate their potential to be used in the development of new anti-tumor agents. Propolis shows an anti-carcinogenic effect against cancers of the brain, head and neck, skin, breast, liver, pancreas, kidney, bladder, prostate, colon, and blood. In-vivo and in-vitro studies have shown that propolis has cytotoxic, anti-genotoxic or anti-mutagenic, anti-proliferative, anti-angiogenic, anti-metastatic, and proapoptotic properties. Its main mechanisms in cancer treatment can be explained as prevention of metastasis, arrest of the cell cycle, induction of apoptosis and alleviation of harmful side effects caused by chemotherapy. The beneficial effects of natural products on human health have been reported in studies to prevent tumor formation and/or suppress the growth of tumors into cancer. In this review, detailed information about the properties, biological effects, and anti-cancer effects of propolis was given by reviewing current literatures.

The poultry industry is based on raising fast-growing chickens. In recent decades, several antibiotics have been employed as growth promoters in the chicken industry, but antibiotic use is banned in the poultry industry due to increased antibiotic resistance and negative impacts on human health. Scientists started searching for alternative antibiotic products as antibiotic resistance increased. Probiotics, prebiotics, organic acids, plant extracts, etheric oils, and immunological stimulants are some of the alternatives. In recent years, these products have improved animal performance, increased animal productivity, prevented and controlled enteric infections, and reduced antibiotic use in animal agriculture. Artemisia, which is currently in scattered form in various research papers, and to draw the attention of experts throughout the world to the Artemisia species' untapped potential. Artemisia annua is also known as sweet wormwood, sweet Annie, and sweet annual wormwood (Chinese: qngho). It's a common wormwood species native to Asia's temperate zones. The active ingredient present in the Artemisia genus is Artemisinin, and chemically it contains both volatile and non-volatile constituents. Biological activities of the Artemisia genus include antibacterial, anti-inflammatory, anti-malarial, anti-coccidial, anti-oxidant, and anti-tumor effects. It has positive effects on growth performance, FCR, gut health, immunity, digestibility, and meat quality of broilers. In conclusion, Artemisia annua is the best alternative product for avoiding anti-microbial resistance in the poultry industry without compromising growth and production. This study aims to review the research conducted on the Artemisia genus.

The aim of this study was to investigate vaginal cytology, haematological and hormonal values, the presence of bacteria in the vagina, and the relationship between these findings in different reproductive periods in cats. The study consisted of 30 healthy non-geriatric female cats that had reachedto puberty. The cats were divided into 3 equal groups (each having 10 cats) as estrus, anestrus and pregnant. The vaginal samples for microbiological and cytological examination andthe blood samples for hormonal analysis and hemogram were taken at the same time. A total of 100 vaginal epithelial cells were counted from the random areas of thevaginal cytology samples on the slide. The distributions of the percentages of the counted cells according to the groups were subtracted and compared. While there was no bacterial growth in 9 (30%) animals, bacterial growth was observed in 21 (70%) animals. There were no bacterial growth in 3 (30%), 4 (40%) and 2 (20%) animals inestrus, pregnant and anestrus groups, respectively. Estradiol (E2) level (42.64 ± 10.62 pg/ml) in estrus animals was significantly higher (P<0.001) than E2 level in pregnant and an estrus animals. The progesterone (P4) level of the pregnant group (12.22±9.35 ng/ml) was higher (P<0.001) than the P4 levels of the anestrus (0.84±0.25 ng/ml) and the estrus group (0.58±0.28 ng/ml), while the P4 levels of the estrus and the anestrus groups were similar. Significant differences were detected only in MCV, MCH and MCHC, within 19 blood parameters. MCV values were found to be lower in estrus animals (45.68±3.75femtoliter) than only in pregnant (51.21±4.99femtoliter) animals (P=0.007). The difference in MCH values between the estrus group (14.37±0.84 pg) and the pregnant group (15.62 ± 1.18 pg) (P=0.003) and the difference in MCHC values between the pregnant group (30.66±1.17 g/dl) and the anestrus group (32.42±1.04 g/dl) (P<0.001) were statistically significant. The presented results may help in the planning of future studies and the comparison of the obtained values.

This sectional study aims to collect data about feeding practices for pace horses in the Aegean and Marmara regions of Turkey. For this purpose, a questionnaire consisting of 69 free text and multiple-choice questions was developed. The questionnaire was implemented on 29-31 August 2014 by personal interviews and was online on social media for ten months. The questionnaire comprised sections on breeder demographic information, farm condition, feeding habit, and nutritional disease. Fifty volunteer horse owners who had a total of 271 horses have participated in the study. Evaluation of the results focused on nutrition practices. Unfortunately, 46% of the respondents were not rasping their horses’ teeth, and an important part of them was not using supplementary oil (78%) or feed additives (84%). Drinking water after exercise (74%) as well as rotten, mouldy, and bacterially contaminated feed (72%) were reported as the most important colic reason by the responders. Based on the results of our study, educational initiatives are needed to inform pace horse owners about appropriate nutrition and related diseases to increase the pace horse race performance.

In the present multidisciplinary study, the researchers on a field trial performed a Social Network approach and a group of 9 calves (3 males/6 females) aged 10 to 16 weeks. A 24 hours digital camera was used for location registration (X-Y position) and interactions on each calf, both individually and collectively. Based on the simple methodology nearest neighbor matrix positive and negative associations were analyzed. The field study lasted 4 weeks and the maximum interaction day was chosen, when individual calf activity was high. To those of 9 calves solely no 2 was infected with giardiasis on the first week, whereas calves with no:2, 7, and 8 were also infected on the second week. No: 4 and 6 were also infected with a total of 5 calves on the third week. This was followed by the final 6 calves in total infected. During the observation period, both by investigators and camera records, infected calf 2 was in close contact with no: 8 (at morning observation) and a slight degree of contact with no: 3 and 4 which were detected with giardiasis on the third and fourt weeks, respectively. Due to close contact with no: 8, infection was determined on the second week, earlier than others (except no: 7). Calves with no: 1 and 5 were never infected nor determined by PCR, fecal smear, or rapid diagnostic test kits throughout the study. In conclusion, the present authors suggested that social networking might be an important predisposing factor for giardiasis infection among calves.

This study was carried out in order to examine a total of 40 drinking water samples taken from 20 locations selected from Mardin and Van provinces in terms of physical properties, heavy metal and mineral contents and to evaluate the quality of drinking water in accordance with the results obtained. Among the ion and mineral analyses of the samples, arsenic, copper, boron, cadmium, cobalt, manganese, nickel, lead, selenium and zinc analyses were made with Inductively Coupled Plasma and Mass Spectrometer, and magnesium analyses were made with Inductively Coupled Plasma-Optical Emission Spectrometer. Fluoride, chloride, nitrite, nitrate, bromide, sulfate and phosphate analyses were also performed by Dionex ion chromatography. Conductivity, pH, ORP, TDS and minimum salt analyses were performed with the Myron L device. As a result of the study, the difference between the fluoride, chloride, nitrite, nitrate, bromide, boron, cadmium, cobalt, zinc, conductivity, TDS, ORP and temperature values of the water samples of the two provinces was found to be significant. In addition, drinking water containing heavy metals was found to be above the limit values set by the Regulation on Water Intended for Human Consumption, nickel was detected in water samples taken from Van, and phosphate was not detected in samples taken from Mardin. The remarkable issues in water samples taken from 40 different locations in two provinces are presented in articles and it has been emphasized that it is important for the people living in this region to present the detected defects to local governments, environmental and public health units and to eliminate the defects.
