The models are designed using both linear and nonlinear components. The developed models are considered in terms of their adequacy and reliability. To improve the quality of the models, the \"folding knife\" method was tested. Verification of models was carried out by methods of sliding control, division of the sample into educational and examination samples and selection simulation. The most important dependencies are highlighted and analyzed. Based on the exterior indicators of heifers around 100 days of age, we obtained a model for predicting the age of the first calving, which was unreliable (P = 0.91) and characterized by a low reduced coefficient of determination (R2adj = 0.21) and a large standard prediction error (SE = 104.75 days). The final parameters of the model of predicting the age of the first calving based on exterior indicators determined at an age of about one year are characterized by high reliability (p> 0.999), good determination (R2adj = 0.58) and quite acceptable differences between predicted and actual values of the age at first calving (SE = 77.01 days). The most adequate is the model based on a double exterior study. It is advisable to use this model in the version of the \"folding knife\" for a more accurate and complete assessment of animals at an early age. This model provides a coincidence of predicted and actual negative estimates of the age of the first calving in 65.7% of cases. The most valuable features for predicting and interpreting the dependence of the age of the first calving on the exterior of heifers are such as the stretch index and oblique body length at 365 days of age. The degree of their influence on the expected age of the first calving is the maximum among all predictors and is η2=16.46% and η2=9.10%, respectively.","PeriodicalId":156452,"journal":{"name":"The Scientific and Technical Bulletin of the Institute of Animal Science NAAS of Ukraine","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678227","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 stimulatory influence of these additions to the piglets' diet on the growth and protein metabolism in their body was shown. The positive effect of the introduction of essential amino acids (lysine, methionine and threonine) and sunflower oil to the diet on the taste of the mixed feed, the intensity of its eating and the growth of piglets was shown in the conducted research. The greatest gains in piglets of the 4th experimental group, where the level of ME in the diet was 13.72 MJ, lysine - 13.8 g / kg, methionine and threonine - 9.2 g / kg of the mixed feed were observed. At the same time, the safety of piglets was directly proportional to their average daily gain. The highest it was in piglets of the 4th experimental group (96.7%), and the lowest in the control group (89.7%). The increase of the content of lysine, methionine, threonine and fat in the piglets' diet led to an increase in the blood plasma of proteins level and a decrease of urea and uric acid. A clear tendency to increased total protein concentration in blood, when increasing the intensity of pre-starter mixed feed intake by piglets with the additional introduction of lysine, methionine, threonine and sunflower oil was observed. It follows from these data that if the level of the most limiting essential amino acids (lysine, methionine and threonine) increases in the diet, the synthesis of blood plasma proteins in the liver of piglets increases and this process is stimulated by the addition of fat. At the same time, feeding young piglets with amino acid and fat additions contributed to a decrease in the content of urea and uric acid in blood plasma. A significant influence of the investigated factors on the use of amino acids and metabolic energy in energy processes in the animal body indicated.","PeriodicalId":156452,"journal":{"name":"The Scientific and Technical Bulletin of the Institute of Animal Science NAAS of Ukraine","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126914901","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 goal of our work was to develop effective ways to sanitize clothing and footwear of workers in the livestock industry. The studies were carried out following the current methodological approaches that are used in agriculture and veterinary medicine. Based on the results of the research carried out, two methods and one device have been developed to ensure a high level of veterinary and sanitary measures in animal husbandry. It has been proven that for the sanitization of clothing of workers in the animal husbandry industry, it is effective to use a disinfectant, which includes the sodium salt of dichloroisocyanuric acid (0.09–0.36%), adipic acid (0.01–0.04%), sodium bicarbonate (0.01–0.04%), sodium carbonate (0.003–0.01%), water (99.887–99.55%) when exposed for 30 minutes. For disinfection of workers' footwear, it is advisable to use disinfectants filled with a disinfectant that contains dichlorantin (0.021–0.21%), 5,5-dimethylhydantoin (0.0164–0.164%), a dispersant (0.012–0.12%), anionic surfactants (0.005–0.05%), corrosion inhibitor (0.01–0.1%), filler (0.0356–0.356%) and water (99.9–99.0%). An innovative device for cleaning and disinfection is proposed - a shoe disinfector, which consists of a waterproof box with a bottom wider than the top, filled with a disinfectant solution, a branch pipe for removing waste solution, a brush shaft, which is fixed in the upper part of the waterproof box, an electric motor with a rotational speed 2 rev/s., Which serves as a drive shaft brush, control panel with a start button and a stop button.

The vaccine consisted of three Y. ruckeri strains (O1 serotype) that originated from rainbow trout cultured on different farms, where fish exhibited clinical signs of enteric redmouth disease. The concentrated vaccine was incorporated into the fish food; treatment was delivered three times at one-day intervals. Two months after immunization, gills were sampled. The vaccination against Y. ruckeri resulted in non-significant changes in TBARS level as lipid peroxidation marker, aldehydic and ketonic derivatives of oxidatively modified proteins level in the gills of trout at the second month after immunization against Y. ruckeri. A significant decrease in superoxide dismutase activity (by 36%, p = 0.002) compared to untreated controls occurred. The alterations in markers of oxidative stress suggest that antioxidant defenses may contribute to the balance between oxidative modification of proteins and antioxidant defenses in the gills of trout vaccinated against Y. ruckeri. We did not find any alterations in the gills after 60 days of immunization. This is likely a result of long-term adaptation to immunization. Understanding the role of oxidative stress in the tissues of vaccinated trout has important implications for the understanding of the complex physiological changes that occur in immunization and also for improving aquaculture practices to maximize tissue growth and health of vaccinated trout. The oxidative stress biomarkers in the gills were sensitive to vaccination against Y. ruckeri and may potentially be used as biomarkers in evaluating vaccine toxicity in rainbow trout.
