The disease caused by carp edema virus (CEV) manifests with lethargy as a primary sign; this observation in koi in Japan gained the disease the name koi sleepy disease (KSD). In the years following the discovery of the virus in Japan, KSD cases have been noted in the UK in koi and common carp. Conducting research in order to expand knowledge of the processes of distribution of CEV in infected fish organs will be helpful for eradication and diagnostic purposes.

The results are presented of the inter-laboratory validation of a liquid chromatography–tandem mass spectrometry method for the determination of eight mycotoxins (aflatoxin B1, deoxynivalenol, fumonisin B1, fumonisin B2, ochratoxin A, toxin T-2, toxin HT-2 and zearalenone) in animal feeds.

Prior to the 2000s, swine dysentery was considered to be caused only by Brachyspira hyodysenteriae with contributing commensal intestinal anaerobes. Nowadays, it is known that the disease is caused by three strongly beta-haemolytic species of the anaerobic spirochaetal genus Brachyspira, i.e. B. hyodysenteriae and newly emerged B. hampsonii and B. suanatina.

Radioactive contamination of the environment is one of the greatest threats after a nuclear accident due to released radionuclides. From a radiotoxicological point of view, the most important radionuclide is caesium-137. Formed mainly during nuclear explosions, caesium-137 can persist in the soil for many years, from where it constantly enters the food chain. One of the elements of ensuring food safety is the monitoring of its radioactive contamination, mainly with radioactive caesium isotopes. The aim of the study was to determine the content of caesium-137 in food of animal origin.

Penconazole (PEN) is a widely applied triazole fungicide. This study sought to define the efficacy of N-acetyl-l-cysteine (NAC) in mitigating PEN-triggered hepatorenal toxicity in rats.

Since the syndesmochorial placental structure of sheep does not allow the passage of large molecules from mother to offspring in intrauterine life, lambs are born hypogammaglobulinemic. The aim of this study is to compare passive transfer of immunity, neonatal morbidity and mortality, and live weight gains at day 120 between lambs receiving colostrum by suckling naturally and lambs given colostrum by bottle. 61 (n=61) lambs born to 43 sheep were randomly divided into two groups. One of the groups (NL group) received the desired amount of colostrum from the mother as they desired after birth. For the other group (BL group), access to the mothers' udder was restricted by a pouch after the lambs were born. BL group lambs were given colostrum roughly 8% of their birth weight by bottle as soon as possible after birth. Afterwards, colostrum freshly obtained from the mother was given to these lambs ad libitum every 4-6 hours during the first 24 hours. Approximately 50 ml of colostrum was taken into sterile containers from all sheep included in the study within the first 30 minutes after birth. Blood samples were taken from lambs for IgG analysis 36-48 hours after the first colostrum intake. Both serum and colostrum IgG analyses were performed by Radial Immunodiffusion (RID) method.  Serum IgG concentrations of lambs in the BL group (3155.41±1245.25 mg/dl) were found to be higher than serum IgG concentrations of lambs in the NL group (2097.02±1213.07 mg/dl). When the results were compared using Independent Samples T test, the difference between the two groups was very statistically significant (p<0.001). Neonatal morbidity and mortality were higher in lambs in the NL group (46.6%, 23.2%, respectively) than in lambs in the BL group (22.6%, 12.9%, respectively). Failure of Passive Transfer of Immunity (FPT) in lambs in the NL group (30%) was much higher than in lambs in the BL group (6.45%). Although the average Live Weight (LW) of lambs in the BL group (40.70 +7.84 kg) was higher than the average of lambs in the NL group (36.47+10.46 kg), this difference was statistically insignificant. In conclusion, giving lambs colostrum by bottle as soon as possible after birth without waiting for lambs to naturally receive colostrum from the mother results in better Passive Transfer and, accordingly, lower neonatal morbidity and mortality, and thus can help reduce economic loss in sheep breeding enterprises.

Lead is one of the most important pollutants in the environment and food chain. This heavy metal causes serious health risks, especially cancer, in humans and animals. Taurine is an amino acid that can be synthesized mainly from methionine and cysteine and is used especially in the food industry. This study investigated the possible protective role of taurine on reproductive performance and DNA damage in Drosophila melanogaster exposed to lead. Lead and taurine were added to the broth of D. melanogaster at 100 µM and 3 mM, respectively, for 15 days. The Comet method was used for the determination of DNA damage. It was found that there was raise in DNA damage in the lead-administered groups, whereas taurine reduced the DNA damage induced by lead. In addition, it was determined that lead caused a decrease, whereas taurine had a positive effect on reproductive performance. As a result, it was determined that taurine prevented the negative effects of lead on D. melanogaster and showed protective properties.

The purpose of this study is to investigate relationship between milk somatic cell count (SCC), total bacteria count (TBC), milk glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and serum paraoxonase (PON) levels, to identify the role of these parameters in subclinical mastitis at cows in the first 100 days of lactation. Animal material of this study consists of 100 Holstein dairy cows which were raised in a farm in Ankara province. Selected animals were hosted under same conditions and had suitable feeding regimen for appropriate period and were in the first 100 days of lactation. Cows which have less than 200x103 somatic cell counts in two different analysis which performed 7-10 days apart considered as healthy (n=50), and which had 200x103 somatic cell counts in two different counts performed 7-10 days apart considered as subclinical mastitis (n=50). Serum paraoxonase (PON) activity was lower in cows with subclinical mastitis than healthy ones (p<0.001), and GSH-Px activity was higher in cows with subclinical mastitis (p<0.001). It was concluded that the changes in milk SOD and GSH-Px levels are affected by the antioxidant system of the udder in subclinical mastitis, that formed oxidative stress and because of that serum PON and milk somatic cell and total bacteria have negative correlation. In conclusion, it was pointed out that serum PON activity can be used as a marker in the diagnosis of subclinical mastitis and evaluation of the antioxidant status of the udder. Also, it was stood out to importance of udder antioxidant mechanisms to understand pathogenesis of subclinical mastitis especially occurs in first 100 days of lactation.

Canine parvoviral enteritis (CPVe) is an important infectious disease that has pretty high morbidity and mortality rates in puppies, which leads to vomiting and diarrhea range from mucoid to hemorrhagic. The objective of this study to investigate the changes in erythrocyte osmotic fragility (EOF) and hematological parameters in dogs with CPVe. Sixteen healthy and twenty-seven infected male and female dogs identified by the CPV antigen rapid-test kit at ages 2-6 months old were used to collect blood samples. A complete blood count and EOF were measured from the samples. Findings of hemogram showed that WBC, RBC, and HCT values were significantly lower in infected dogs (the p-value of the first one is p<0.001, other two ones are p<0.05) compared to healthy controls. The infected dogs had non-significantly lower NEU, EOS, and PLT values, and higher LYM, MON, MCV, MCH, and MCHC values than control group (p>0.05). Although the hemolysis rate of infected dogs' erythrocytes at the concentrations of 0.4 - 0.1 % NaCl were higher than that of healthy dogs, this difference was statistically significant at only 0.3% NaCl (p<0.05). In addition, the median corpuscular fragility (MCF), equal to the NaCl concentration that lyses 50% of erythrocytes, of dogs with CPVe (0.42%) was higher than the MCF values of the control group (0.39%), but not statistically significant (p>0.05). In conclusion, besides the hematological findings revealed that WBC, RBC, and HCT values were significantly lower in dogs with CPVe than that in healthy dogs in this study, it was reported for the first time that canine parvovirus significantly increased osmotic fragility of RBCs at 0.3 % NaCl concentration compared to the control group. We concluded that to consider of these, particularly affected, blood parameters may be useful for determining the prognosis of CPVe.

The stiff structure of the body, or skeleton, provides the body with its overall form, permits movement, generates blood cells, and protects delicate organs. This research was done to prepare the quail (Coturnix coturnix) skeleton for the avian anatomy museum and educational facilities. A total of five matured Quails (at the age of 6 months) were collected from a commercial quail farm, in Khulna, Bangladesh. The carotid artery and jugular vein were carefully dissected before skinning each quail with feathers, removing all viscera, combs, and wattles. To adequately disintegrate the muscles, ligaments, and tendons, different body sections of the bones were separated, wrapped in markin cloth, and cooked in a 3% solution of soda water for 1.5 hours. The body parts were then maintained in separate solutions for 5 days. After five days, the bones were thoroughly cleaned by soaking them in a 5% hydrogen peroxide solution for 30 minutes, and rinse them under running water. To maintain the order of the vertebrae in the various segments, a steel wire was inserted into the vertebral foramen. After proper sun drying for 25 days, a set of bony components from different parts (axial and appendicular) of the body was finally found and articulated to rise into a whole skeletal frame. Therefore, the present work denotes time-consuming and easy preparation of the avian skeleton as well as the skeletal framework will be helpful for veterinary students in the avian anatomy laboratory as well as to enhance the elegance of the anatomy museum.
