The research was carried out in the conditions of the breeding breeder for breeding pigs of the large white breed of the experimental farm and the laboratory of animal husbandry and fodder production of the Institute of Agriculture of the Northeast of the National Academy of Sciences, as well as the laboratory of animal husbandry of the State University “Institute of Grain Crops of the National Academy of Sciences”. The work was carried out by the program of scientific research of the National Academy of Agrarian Sciences of Ukraine No. 31, “Genetic improvement of agricultural animals, their reproduction and preservation of biodiversity” (“Genetics, conservation, and reproduction of biological resources in animal husbandry”) and No. 30 “System of organizational and technological solutions for adaptation of animals to climate change for the production of animal husbandry products (“Climate-adaptive and organic animal husbandry”). The object of the study was sows of a large white breed of French origin. The evaluation of the animals of the specified production group by indicators of reproductive qualities was carried out taking into account the following characteristics: total farrowing, live piglets total, weight, fertility, weight, milk yield, kg; weight of the nest at the time of weaning at the age of 28 days, kg, preservation, %. The viability index was calculated according to the method of V. P. Kovalenko et al. (2012), index “level of adaptation” – Smirnova V.S. (2003), selection index of reproductive qualities of the sow (SIRQS) – O. M. Tsereniuka et al. (2010). It was established that the difference between sows of different adaptation levels by age and fertile insemination is (17.0 days; td=2.70), life span (17.0 months; td=9.04), the number of farrowing obtained (3.3 of farrowing; td=13.20), the number of live piglets obtained (46.2 head.; td=10.52), multifertility (1.2 head; td=4.00), litter weight at the time of weaning at the age of 28 days (3.5 kg; td=3.21). Animals of the specified production group with a viability index variability of 90.75-144.55 points prevailed over peers with a viability index of 39.75-77.46 points in terms of age and fertile insemination, number of live piglets obtained, multifertility, nest weight at the time of weaning at the age of 28 days and conservation by an average of 11.43%. The correlation between life expectancy, duration of breeding use, signs of reproductive qualities of sows, and indices of \"adaptation level\" (RA) and viability (I) ranges from –0.758±0.0371 (tr=20.45) to +0.859 ±0.0228 (tr=37.62). The maximum increase in additional production was obtained from sows of the 1st experimental group of intrabreed differentiation according to the index \"level of adaptation\" (+3.31%) and according to the viability index (+11.24%), and its value is +155.80 and +529.08 hryvnias obtained from 1 ","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"10 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140968952","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}

E. tenella and E. maxima were identified from faeces samples of sick broiler chickens. For three weeks (21 days), the sick bird the feed supplement EIMERIX® was added in feed at a dose of 0.5 g per 1 kg of feed, or 100 mg of sodium monensin per 1 kg of feed (experimental group). The control group consisted of broiler chickens suffering from coccidiosis, which were not given the supplement or any other anticoccidial drugs. \u0000The main criteria for demonstrating the estimation of the feed additive EIMERIX® were: the number of Eimeria oocysts in feces; mortality and morbidity of poultry associated with coccidiosis. Additional indicators of the effectiveness of the feed additive were: average live weight; average daily increase in live weight of poultry; average daily feed consumption, the ratio of the amount of feed consumed to growth; data of bird health monitoring during the experiment. \u0000On the 21st day of the experiment, the excretion of Eimeria oocysts in the feces of broiler chickens with coccidiosis practically stopped (<100 oocysts/g of feces), what was confirmed by the absence of clinical signs of coccidiosis in the birds. Addition of EIMERIX® additive in feed contributed for the reduction of morbidity and mortality among sick birds. More live weight gains and lower feed conversion ratios were observed in Eimeria disease birds treated with a feed additive versus untreated birds. \u0000The results of the study showed that the use of EIMERIX® feed additive for broiler chickens with coccidiosis, in the recommended by the manufacturer dosage, causes a decrease of the eimeria infection degree of the bird, reduces its morbidity and mortality, and also contributes to an increase of average daily gains and improvement of feed conversion.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"48 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140969368","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}

Piglets become infected immediately after birth through ingestion of sporulating oocysts from previously infected litter, as sows are considered a secondary source of infection for them. Proper housing and hygiene, which reduce the accumulation of oocysts in the environment and exposure of piglets to sporulation oocysts, are key to disease prevention. \u0000The goal of the work. To determine the effectiveness of eimeriostatics for the mixed course of isosporosis and cryptosporidiosis in piglets. \u0000The effectiveness of the drugs was determined on 14-day-old piglets of the breed ''Velika Bila''. The piglets of the first experimental group were given the drug Turil 5%, the second experimental group - Brovitacoccid, the third experimental group - Amprolev-plus.\" The dynamics of the infestation of piglets with isospores and cryptosporidia after the use of the drugs and their effectiveness were determined on the 7th, 14th and 28th days by counting the number of oocysts in 10 fields of view of the microscope according to the method of N.P.

Piperazine and its derivatives are well-known anthelmintic drugs used in human and veterinary medicine. Piperazine is a heterocyclic compound without any chromophore groups with a low molecular weight (86.1 g/mol), which makes its detection in biological samples by LC-MS/MS difficult. We have developed the confirmatory technique for the direct UPLC-MS/MS assay of piperazine residues (without prior derivatization) in animal tissues after sample purification using solid-phase extraction. The proposed sample preparation includes homogenization, liquid-liquid extraction using acetonitrile, concentration and purification of samples from matrix components using SPE cartridges Oasis HLB (Waters) and with additional concentration of the eluate by drying. The analysis of the prepared samples was carried out by the method of ultra high performance liquid chromatography with tandem mass spectrometric detection using the precursor ion of 87.0 m/z and product ions of 43.9 and 70.0 m/z (ES+ ionization, multiple reactions monitoring mode). \u0000In order to experimentally confirm the fitting-for-purpose of the developed confirmatory method for clinical studies of veterinary drugs based on API piperazine and to assess the safety of food products of animal origin for piperazine residues, the validation of the developed UPLC-MS/MS method for the determination of piperazine in muscle tissues and liver of pigs was carried out using approaches described in EMEA/CVMP/VICH/463202/2009 and in accordance with Regulation (EU) 2021/808. In the process of UPLC-MS/MS technique validation, various key operating parameters were established for both investigated matrices: limit of detection, limit of quantification, linearity, specificity, accuracy, trueness. In particular, it was established that the developed method provides determination of piperazine residues in muscle tissues and liver of pigs with a sensitivity of 50 and 400 μg/kg, respectively.The developed and validated confirmatory UPLC-MS/MS method for the determination of residual amounts of piperazine is highly sensitive, highly selective and rapid, appropriate for the control and monitoring of the safety of animal meat and liver samples, as well as to provide analytical support for clinical studies of veterinary drugs based on API piperazine and its derivatives.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"55 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140969258","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}

The isocratic mode of elution was carried out for 10-15 min. Nicarbazin retention time depended on the eluent flow rate and ranged from 2.4 to 8.8 min. The repeatability of measurements was assessed by analyzing the calibration curve of nicarbazin standard solution. Feed samples were extracted with dimethylformamide. The samples were concentrated by drying, dry residues were reconstituted by the mobile phase, degreased with hexane and subjected to chromatographic separation. The specificity of the analytical method was tested by comparing the chromatographic separation of the feed sample spiked with nicarbazin standard solution with the control feed sample. The extraction degree of the spiked feed samples in the range of 20.0-50.0 mg/kg of nicarbazin was considered to determine the bias as the practical assessment of the validation parameters: trueness, linearity, repeatability and intermediate precision. The method was linear over this range of nicarbazin concentrations. The average degree of nicarbazin extraction from spiked feed samples is 99.1%. The correlation coefficient of the matrix matched calibration curve was more than 0.99.

Inactivated and live vaccines have been proposed for this purpose. Immuno-prophylaxis allows to reduce the possibility of vertical and horizontal transmission of salmonella and the level of spread of microorganisms in the environment. Vaccination can reduce the degree of clinical manifestation of the disease, mortality and invasion of the pathogen in various organs, but does not prevent the infection of the bird. In Ukraine, vaccination against poultry salmonellosis is an additional measure of infection prevention and elimination. The basis for the introduction of mandatory vaccination is the presence of this infection in more than 10% of farms (according to the generalized data of laboratory studies). Vaccination is carried out in accordance with Commission Regulation CR (EC) No. 1177/2006. 3 for the specific prevention of salmonellosis, inactivated and live vaccines, DNA vaccines, subunit vaccines, etc. are used. More than 20 commercial vaccines against poultry salmonellosis have been registered in the world. 11 vaccines are registered on the market in Ukraine, of which 1 is a preparation of a domestic manufacturer. \u0000For the prevention of salmonellosis infection in poultry farming, it is necessary to use a systematic approach, which involves the implementation of veterinary and sanitary measures to prevent the introduction of pathogens of infectious diseases into the farm, including monitoring and diagnostic studies throughout the entire technological chain of production, the use of effective drugs specific and at critical control points (НАССР) in order to ensure the absence of salmonella in the parent flock of poultry, in feed and in water. The system of effective control of epizootic welfare in relation to poultry salmonellosis involves the use of specific preventive measures that ensure long-term and reliable protection of poultry from infection and systematic microbiological monitoring of the spread of salmonella.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"50 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140970728","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}
