In Croatia, values of reproductive traits of Romanov sheep are below the average expected for this breed, indicating the need for improvement of these traits to exploit the breed’s full reproductive potential. This study was conducted on 260 Romanov ewes located at a commercial Romanov sheep farm in Croatia. All ewes were kept under similar conditions, and reproductive management was based on accelerated lambing with continuous mating. Linear models with fixed effects were used to estimate the influence of year of birth/lambing, season of birth/lambing, ram, parity and litter type on litter size (LS), age at first lambing (AFL) and lambing interval (LI). Average LS was 2.11 ± 0.71, while the year of lambing and parity were the most important factors affecting this trait. The smallest litters were recorded after 1st parity (1.77 ± 0.06), and the largest after 5th parity (2.21 ± 0.08). AFL averaged 388.5 ± 72.4 days. All investigated non-genetic factors had a significant (P<0.05) influence on AFL, with year of birth as most important. The average LI was 241.2 ± 70.8 days. A significant (P<0.05) influence of all factors on LI was observed. Ewes lambing in spring (200.2 ± 7.9 days) or summer (190.5 ±6.6 days) had a significantly (P<0.05) shorter LI than ewes lambing in autumn (227.7 ± 8.3 days) or winter (237.2 ± 6.7 days). The longest LI was observed after the first parity (284.0 ±5.5 days). Average values for reproductive traits in the examined population of Romanov sheep were higher than those reported in the official Croatian database for breeding sheep. Non-genetic factors have a significant influence on the variation of reproductive traits of Romanov sheep, and therefore should be considered when assessing ewes’ reproductive performance.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46663216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, we conducted this study at an aquaculture farm in Khemis Meliana (Ain Defla, Algeria). The study included six royal carp broodstock, 4 females and 2 males. Hormone injection was performed in the dorsal muscle under the fin. The induction of carp was done successively in females by GnRH at a dose of 3 mg/kg and in males by hCG at a dose of 500 IU per kg weight. Fertilisation was done artificially by the dry method. After incubation of eggs, a binocular magnifying glass was used to check the condition of eggs and the development of the embryos over time. The results obtained show that the artificial reproduction of this species was possible, with success of ovulation and fertilisation, and hatching and growth of the larvae. Stripping was done after 24 h of hormonal stimulation at a temperature of 21°C. Disaggregation of eggs was performed efficiently with whole milk. The total number of eggs was 552,000 eggs with a weight of 1104 g. The average latency time was 22 hours. The hatching rate after 3 days of incubation on artificial spawning grounds at 21±1°C was 441,600 larvae (80%). Larvae food follow-up started from the 3rd day post-hatching with a combination natural food (rotifers) and artificial food. At the end of this experiment, we can conclude that it is possible to improve reproduction through the proper use of hormonal stimulation techniques and by improving feeding and abiotic factors that are dominant in fish farming.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41355357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This formation attaches to a certain surface, particularly the epithelium. The ability to form a similar structure has been observed in Pasteurella multocida, the causative agent of anthropozoonoses that affect domestic and wild animals, birds, companion animals and humans. The spectrum of pathogenetic action of P. multocida is wide and associated with the development of respiratory and multisystemic pathology, bacteraemia and other manifestations. Timely detection of P. multocida and treatment of the diseases it causes in farm and domestic animals is important to limit economic losses and improve social security. The main objective of this study was to determine the pathogenicity of P. multocida, its ability to form a biofilm, its resistance to antibiotics, and to identify the genes responsible for the formation of dermonecrotic toxin and biofilm formation. The paper presents the results of a study of 11 isolates of P. multocida: six isolates (54.5%) from rabbits, two isolates (18.2%) from dogs, two isolates (18.2%) from cats, and one isolate from pigs (9.2%). In all isolates, the gene ptfA was detected. This gene encodes the formation of type 4 fimbriae and participates in the formation of the biofilm, and the studied cultures in vitro formed a biofilm of different densities. The genome of eight isolates (72.7%) included the toxA gene (provides the formation of dermonecrotic toxin), while 45.4% of isolates had a complete set of the studied signs of pathogenicity, both in phenotypic (biofilm formation, mortality for laboratory animals) and genotypic (presence of toxA, ptfA) traits, and three isolates (27.3%) showed signs of multidrug resistance. The virulence of the toxA-negative isolates of P. multocida was lower than in toxA-positive isolates. The culture with the highest virulence (0.5x 101 CFU) and extreme resistance to antibiotics formed a biofilm of the highest density. The association of the gene in the biofilm-producing mechanism needs further evaluation, and further research is needed to identify the relationships between pathogens in Pasteurella multocida isolates from different species of animals and humans.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48024756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modification and optimisation of the protein precipitation (PPT) sample preparation procedure and HPLC with diode array detector (DAD) instrumental method were carried out to ensure conditions suitable for FF analyses in pig plasma samples. Stable supernatants with good plasma mean recoveries of FF (99.8% ± 0.7%RSD) were achieved using 1% v/v phosphoric acid solution in methanol and 10% w/v sodium chloride in aqueous solution. The PPT-HPLCDAD method’s detection limit of 0.004 μg/mL and quantification limit of 0.013 μg/mL provides high sensitivity for analyses of FF in plasma samples. In addition, the optimisation of method conditions resulted in shorter extraction and analysis time and less solvent consumption, which stresses the sustainability of this method in analytical chemistry. The optimised and validated PPT-HPLC-DAD method was applied in a comparative study of FF in pig plasma after administration of veterinary medicinal products. The study was conducted on fattening pigs following repeated intramuscular administration of two similar solutions for injection at a dose of 20 mg FF/kg bodyweight (test groups 1 and 2). The solutions for injection contained the same FF concentration, i.e., 300 mg/mL, but differed in excipients. The aim was to examine the influence of administrated solutions for injection on the extent of exposure to FF in pig plasma. The dynamics of kinetic profiles of FF in pig plasma from both treatments correspond to the FF kinetic profiles published in similar studies. However, differences were observed in the concentrations of FF, which were constant throughout the study, and statistical differences between the test groups were confirmed (P<0.05). Though these findings suggest the possible influence of excipients, a full comprehensive conclusion on the influence of administrated solutions for injection on FF exposure in pig plasma requires additional research.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49459118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
