This study was performed to investigate the effect of dietary aspirin (A) on some performance traits in broilers using a completely randomized design, 120 one-day-old male broiler chicks Ross 308, three levels of aspirin (0, 50, and 100 mg/kg), in 4 replicates, each including 10 chicks, during 42 days. The effects of different levels of aspirin, added to a basal diet, on performance, carcass characteristics, and digestive organs of chicks were investigated. Data analysis was performed by SAS statistical software and the comparison of the means with Duncan's test. The results showed that the chickens fed by a diet containing 100 mg/kg of aspirin had the highest feed intake and weight gain and the best feed conversion ratio compared to the other treatments. Also, the lowest production cost and the best European factor were related to treatment A100 (P<0.05). In addition, the use of the same level of aspirin resulted in a significant increase in some carcass properties and a decrease in ventricular fat compared to the control (P<0.05). So, based on the results of the present study, the use of 100 mg/kg aspirin in the diet of broilers is recommendable to improve some performance parameters.

The objective of this study was to investigate polymorphisms of MASP2, TG5 and DQA1 genes using PCR-DNA sequencing in seventy Holstein, and Brown Swiss dairy cows (35 cows each). Under complete aseptic condition, blood samples were collected from each animal into tubes containing disodium EDTA as an anticoagulant for DNA extraction. PCR was carried out for amplification of 305-bp of MASP2, 545-bp of TG5, and 373-bp of DQA1 genes. DNA sequencing assessment elaborated nucleotide sequence variations in forms of single nucleotide polymorphisms (SNPs) between two breeds. The SNPs identified in the investigated genes for Holstein breed were A46G in MASP2 gene and C371T in TG5 gene. A characteristic T53C SNP was also reported for Brown Swiss breed in DQA1 gene. Chi-square revealed a significant variation in distribution of all identified SNPs (P < 0.001). Consequently, identified SNPs could be used as candidates and a reference guide for efficient characterization of Holsteins, and Brown Swiss breeds; therefore, developing a marker assisted selection (MAS) for production and immunity traits in breeds of dairy cattle.

Endometritis is one of the most common disorders that negatively influence reproductive performance in dairy cows. The purpose of this study was to determine the predictive factors of the clinical cure of endometritis. A total of 700 Holstein dairy cows were examined for signs of clinical endometritis between 30 and 40 days in milk (the first examination in the time of clean test). A total of 131 cows with clinical endometritis were assigned for treatment. Cytological examination, reagent test strips, and characteristics of reproductive organs were evaluated at the time of treatment (the first examination) and two weeks after the treatment (the second examination: for evaluation of response to treatment of endometritis). After evaluation of treatment, cows were grouped into the responsive (n=56) and unresponsive (n=75) to treatment. Percentages of non-degenerated neutrophil (NDN), degenerated neutrophil (DN), total neutrophils and leukocyte esterase activity were significantly higher (P<0.05) in the unresponsive cows than those of responsive ones to treatment at the second examinations. Moreover, the nitrate test was significantly higher in the unresponsive group than the responsive group at the first examination. However, protein concentration and percentages of lymphocyte cells were significantly higher in the unresponsive animals than the responsive cows at the first and second stages of examination (P<0.05). Increasing of lymphocytes percentage, protein concentration, and nitrate test at the first stage of examination in the unresponsive cows showed more sever of inflammatory conditions and uterine infection in the unresponsive cows. Evaluation of these factors can predict the clinical cure of endometritis in dairy cows.

The present study was carried out to determine the virulence gene profiles associated with Salmonella subsp. enterica strains recovered from cattle and sheep samples by polymerase chain reaction (PCR). A total of 84 Salmonella isolates belonging to 10 serovars were screened for presence of 8 different virulence genes (invA, pefA, sefA, pipB, sseC, ssaP, spvC and iroB) using their specific primers. Different distribution patterns of these genes were noticed amongst the isolates. While the iroB gene was the most identified (n= 65, 77.4%), the sefA gene was not detected in all tested strains. pefA and spvC genes were detected in S. Typhimurium only with a rate of 3.6%. The four other genes were found to be present in 61.9% each. Occurrence of virulence genes did not vary significantly (P> 0.05) by serovar or animal species, neither by type of sample. The presence of all screened genes was significantly associated with resistance to at least one antibiotic from different classes except quinolones. These results show that transmissible pathogenic Salmonella strains are circulating in slaughterhouses in Algeria.

In this case, it was aimed to report the clinical, hematological and pathological analysis results of a lamb born as infected with border disease virus (BDV). Severe central nervous system findings such as standing inability, continuous teeth grinding, muscle fasciculations in the head, ear and tail, hair loss around the eyes, lips and ears, abnormal appearance of the fleece, ataxia/rhythmic tremor and incoordination were detected in the case of lamb infected with BDV. The presence of BDV antibody and the levels of Triiodothyronine (T3) and Thyroxine (T4) were investigated in the serum samples for definite diagnosis. The tissue samples obtained from the brain and cerebellum were evaluated histopathologically and diagnosis of BDV was confirmed by necroscopic findings.

Abstract: This paper presents the first study conducted in Algeria to determine the pre and post-race hematological and biochemical parameters of horses of a 90 km endurance race for eliminated horses’ category and those who completed the races with good performance. This study was conducted on 15 endurance horses (10 Arabian Thoroughbred, 4 Arabian-Barb and 1 Barb). Nine (9) horses successfully completed the endurance race, whereas the other 6 were eliminated. Blood samples were collected from each animal before and after the end of the race. Whole blood samples were used for measuring the blood-biochemical parameters. Our results showed a significant increase in the hematological parameters (RBC, HB, Ht and MCV), the total leucocyte count, neutrophils and platelets for the group of horses who finished the race successfully. A significant decrease was noticed for the lymphocytes and eosinophils numbers while serum biochemical parameters showed a significant increase of Ca, TG, urea, U-A, AST and CK and a decrease of Mg, CHE, GLU and ƔGT. This study showed that, for the eliminated horses, there were significant changes in values of the total leucocytic count, lymphocytes, neutrophils, HB and Ht as compared to good performance horses. Serum biochemical parameters showed a significant increase of TG, U-A, AST and CK and a significant decrease of Ca, Mg, CHE and ƔGT. Most of the hemato-biochemical parameters of both the eliminated horses and those who completed the race successfully depicted significant differences. The results of this study suggested that biochemical findings could help identify horses with an increased risk of developing metabolic alterations before their elimination during competitive endurance races of different distances. Therefore, proper management protocols, standard feeding and watering with proper preparation of animals before the race could prevent electrolytes imbalance and pathological affections during racing.

This study aimed to determine the direct and indirect effects of the independent variables presented by the lactation lenght (LL), age of calving (CAGE), and daily milk yield (DMY) on the dependent variable of lactation milk yield (LMY) in Anatolian buffaloes. In this study, a total of 3761 LMY records of the 834 Anatolian buffaloes calving between 2012 and 2017 in Tokat province and around were used as the research material. In the study, the simple correlation coefficients between the dependent variable of LMY and independent variables were determined positive and significant (P<0.001). The research specified the direct determination coefficients of the independent variables of the LL, CAGE, and DMY on the dependent variable of LMY as 0.378, 0.004, and 0.350, respectively. The path coefficients related to LL, CAGE, and DMY were determined as 0.615, 0.021, and 0.592, respectively. Since the DMY and LL examined in the study had a high direct impact on the lactation milk yield, therefore it could be suggested that using these data as criteria in breeding programs conducted in the herds evaluated in the study will increase the success in the selections applied.

A case of prepubic tendon rupture in a Romanov ewe in which four live lambs were removed by cesarean section is presented. A three-year-old ewe, on the 142±3 days of the second gestation was brought to the Siirt University Animal Health Application and Research Center with a sudden downward expansion of the abdomen during the last one day. When ewe was examined reluctance to locomotion, mild depression, tachycardia, tachypnea and abdominal peculiar enlargement on the left side more than right side were noticed. Because of this case was detected early the general condition was not so bad and clinical examination revealed that swelling was non-painful and non-edematous. Ultrasonography was performed to detect viability of the fetuses, and to eliminate possibility of hernia of the abdominal muscles. Based on anamnesis, abdominal palpation, and clinical examination, this case was diagnosed with prepubic tendon rupture. The prognosis of saving the lives of ewe and fetuses depends on successfully handling all aspects of the case in the last period of pregnancy. Although it is not possible to repair the abdominal integrity surgically in cases of prepubic tendon rupture in the ewe, a planned cesarean operation is indicated to increase the survival rates of both ewe and lambs.

In this study, the mixtures obtained by mixing quinoa flour with wheat flour in different proportions were added to chicken meat patties and their effects on some quality characteristics were investigated. The yields of the meatballs prepared with the mixes containing 50% and 100% quinoa flour were higher than those of other meatballs (69.59% and 69.71%, respectively). The moisture retention of the fried meatballs prepared with mixtures containing 50%, 70% and 100% quinoa flour was found to be 45.80%, 45.97% and 51.09%, respectively. The results indicated that the moisture retention of these meatballs was higher than those of meatballs containing 30 and 0% quinoa flour. In contrast, oil absorption rates in the fried samples were in the range of 4.46-5.65% for all quinoa-containing samples and were lower compared to the control sample. Firmness decreased in meat patties prepared with mixtures containing high quinoa rates. It was observed that quinoa flour did not have a negative effect on quality factors. It was concluded that especially the mixtures containing 30% and 50% quinoa flour can be recommended.

In vitro antimicrobial and antibiofilm forming activities of Origanum munzurense extract were investigated against some gram-positive bacteria and yeast strains. Liquid microdilution method and microplate method were used for antimicrobial and antibiofilm forming activities, respectively. Minimal inhibitory concentration values were found to be 2 mg/ml for Enterococcus faecalis ATCC 29212, 64 mg/ml for Listeria monocytogenes RSKK 02028, 2 mg/ml for L. monocytogenes RSKK 472, 2 mg/ml for Bacillus cereus NRRL 569 , 128 mg/ml for S. aureus ATCC 25923, 32 mg/ml for S. aureus (MRSA) ATCC 43300 strain, 64 mg/ml for Candida tropicalis ATCC 13803, 2 mg/ml for C. albicans ATCC 90028, 1 mg/ml for S. aureus FRI 918 and 1 mg/ml for Staphylococcus epidermidis ATCC 12228 strain. The extract prevented the biofilm formations of E. faecalis ATCC 29212, S. aureus FRI 918 and S.epidermidis ATCC 12228 at concentrations of 2 mg/ml, 500 µg/ml and 250 µg/ml, respectively. No biofilm formation was observed for the other bacteria tested.As a result, Origanum munzurense extract has antibacterial and antibiofilm activity on the selected pathogenic microorganisms tested. Due to these properties of O. munzurense, it could be considered as a plant-based antimicrobial agent to be used especially in the food industry.

Yalçin","doi":"10.12681/jhvms.28910","DOIUrl":"https://doi.org/10.12681/jhvms.28910","url":null,"abstract":"In vitro antimicrobial and antibiofilm forming activities of Origanum munzurense extract were investigated against some gram-positive bacteria and yeast strains. Liquid microdilution method and microplate method were used for antimicrobial and antibiofilm forming activities, respectively. Minimal inhibitory concentration values were found to be 2 mg/ml for Enterococcus faecalis ATCC 29212, 64 mg/ml for Listeria monocytogenes RSKK 02028, 2 mg/ml for L. monocytogenes RSKK 472, 2 mg/ml for Bacillus cereus NRRL 569 , 128 mg/ml for S. aureus ATCC 25923, 32 mg/ml for S. aureus (MRSA) ATCC 43300 strain, 64 mg/ml for Candida tropicalis ATCC 13803, 2 mg/ml for C. albicans ATCC 90028, 1 mg/ml for S. aureus FRI 918 and 1 mg/ml for Staphylococcus epidermidis ATCC 12228 strain. The extract prevented the biofilm formations of E. faecalis ATCC 29212, S. aureus FRI 918 and S.epidermidis ATCC 12228 at concentrations of 2 mg/ml, 500 µg/ml and 250 µg/ml, respectively. No biofilm formation was observed for the other bacteria tested.As a result, Origanum munzurense extract has antibacterial and antibiofilm activity on the selected pathogenic microorganisms tested. Due to these properties of O. munzurense, it could be considered as a plant-based antimicrobial agent to be used especially in the food industry.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41401761","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}
