The reproductive ability of bovine animals largely depends on these effects, whilst embryo transfer is increasingly being used as a reproduction method. In this study, we established the differences in the implantation ability of heifers that were treated (N=17) with selenium (Se) and vitamins AD3E, and non-treated heifers. Upon transfer, we took blood samples from both groups and used the total antioxidant status (TAS) value to analyze the presence of reactive oxygen species (ROS), the levels of non-esterified fatty acids (NEFA) and the levels of vitamin E and Se in blood plasma. In the study, we were able to demonstrate that preventive measures in the form of supplementation of vitamin E and Se, mitigate the effects of oxidative stress, strengthen the ability of an organism to improve the dynamic relationship between free radicals and antioxidants, improve the energy status of cattle, positively impact reproductive parameters and increase the success rate of embryo transfer. The difference in the number of successful embryo implantations between the control and treated group was statistically significant, with 64.7% of treated heifers being pregnant after embryo transfer and giving birth to healthy calves. In the control group, the implantation success rate was 41.2%. The supplementation of antioxidants in the form of a combination of vitamin AD3E and Se, proved to be a good method for strengthening the defense of an organism and an effective mean of preventive clinical approach for improving fertility parameters.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"87 - 101"},"PeriodicalIF":0.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48637519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is aimed to estimate CH4 emission and metabolic status in dairy cows via the methane concentration profile as a tool for analyzing the CH4 production pattern. The study included eighteen cows whose enteric CH4 emission was measured during three consecutive days in three periods: 2 hours before (P1), 2–4 hours (P2) and 6–8 hours (P3) after the morning feeding. Based on CH4 enteric emissions, cows were divided into two groups (n=6, respectively): HM (average CH4 concentration: 5430.08 ± 365.92 ppm) and LM (average CH4 concentration: 1351.85 ± 205.20 ppm). Following CH4 measurement, on day 3, venous blood was sampled to determine the indicators of the metabolic status. HM cows had significantly higher average CH4 concentrations, maximum and average CH4 peak amplitude than LM cows in all measuring periods (P1-P3), while the number of CH4 peaks tended to be higher in HM than in LM cows in P2. There were no differences in the maximum and average CH4 peak width and average distance among two CH4 peaks between examined groups of cows. HM cows had significantly higher total protein concentrations and significantly lower total bilirubin and NEFA concentrations than LM cows. In conclusion, HM cows have a greater number of eructations and release more CH4 per eructation than LM cows, hence the differences in metabolic status are most likely related to the differences in their liver function.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"71 - 86"},"PeriodicalIF":0.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46044547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has taken on major economic importance in countries like Morocco. In addition to the classical virus (RHDV), a novel emerged genotype (RHDV2) is circulating, especially in the north shore of the Mediterranean basin since 2010. Many small animal farmers reported clinical cases from several rabbitries in Agadir (Morocco) despite systematic vaccination against the RHDV. The main objective was to characterize the current RHDV strains circulating in the studied area to help to choose an adequate vaccine. For that, we extracted viral RNA from rabbit livers, carried out the PCR analyses, and we sequenced the viral structural capsid protein (VP60) of the RHDV. The phylogenetic analysis results allowed us to state that the novel genotype (RHDV2) is circulating in the studied geographical area, and to characterize the isolated sequences. As a conclusion, we recommend updating RHD epidemiological relating data and reviewing the vaccine protocols by both targeting RHDV (GI.1) and RHDV2 (GI.2) in any future preventive program.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"433 - 441"},"PeriodicalIF":0.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42345030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These data confirm the presence of a high prevalence of these viruses on Italian territory. To the authors’ knowledge, this study describes findings that have never been evaluated before, such as iron status in retrovirus-infected cats and urinalysis in FeLV-positive cats. In this study, FIV-positive cats were more likely to have higher serum protein concentration and lower albumin-globulin ratio than other groups of cats. Lower urine specific gravity and higher urine protein to creatinine ratio were also detected for FIV-positive cats when compared with negative and healthy cats. FeLV-positive cats were more likely to have cytopenia, decreased haemoglobin, haematocrit and RBC compared with other groups of cats. The data obtained underline the importance of considering retroviral infections in the presence of a broad spectrum of risk factors and laboratory anomalies.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"419 - 432"},"PeriodicalIF":0.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46008444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In situations where a bone fracture occurs, our intention is to surgically position in an appropriate morpho-anatomical position. For osteosynthesis we used vipla wire and micro plates with corresponding screws. The aim of our research was to evaluate the optimal time for the removal of the osteosynthetic material, fracture site biomechanical stability, and measurement of the callus thickness. For this research ten 4 months old rabbits with right leg femur fracture were used. Osteosynthesis was done with titanium micro plates, corresponding screws and vipla wire. Experimental animals were observed through the post-operative period at the first and seventh postoperative day and there on at 2, 4, 6, 9, 12 weeks. Further additional fixation was needed in one of the rabbits in the second week. The postoperative period provided us information about the optimal moment for the removal of titanium micro plates. It showed that over a period of six weeks, the bone had almost all normal biomechanical properties. Significantly greater strength and rigidity of the recovered femur were obtained after 12 weeks. Micro plates that were removed after 4, 6 or 9 weeks, did not need furhter fixation and therefore fixation was not applied, compared to those placed during the 12 weeks. X Ray evaluation provided us with follow up results of fracture healing. The results suggest that it is acceptable to remove titanium micro plates after a period of healing, that is, after the formation of the callus and bridging of the fracture gap and diastasis with newly formed bone.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"442 - 452"},"PeriodicalIF":0.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49019019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its principle is the change in the frequency of wave blood that moves with respect to the source of the wave (probe). In a testicular examination, the use of Doppler can also be very useful for detecting abnormalities or pathological conditions. The aim is just to characterize the flow in arteria testicularis in clinically healthy dogs aged 1-5 years. Twelve dogs were included in the study, of which 6 were rough collies weighing approximately 23 kg and 6 were standard dachshunds weighing approximately 9 kg. The pulsatility index (PI) and resistance index (RI) of a.testicularis, as well as the dimensions of the testicles - height and depth, were assessed by ultrasonographic examination using the ALOKA ProSound Alpha 6 ultrasonographic device (Hitachi-Aloka, Japan). The statistical evaluation of the results shows that the differences between the averages of both measurements of PI and RI indices are highly significant, so the weight of the individual had a high effect on the measured values of PI and RI indices. The depth of the testicles was also directly related to the increasing values of PI and RI indices and to the weight of the dogs, in contrast to their height, which did not show any statistical significance in this respect. The measured values and findings may in the future also serve as a basis for determining reference values in testicular ultrasonography according to the weight of dogs, which may be beneficial in clinical status assessment, diagnosis of various pathological conditions, or predicting spermatogenesis and fertility of the individuals.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"72 1","pages":"453 - 467"},"PeriodicalIF":0.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44869985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
