    Pig farming has a long tradition in Russian agriculture. The objectives of the present study were to investigate some indicators of blood biochemistry and hematology, and mineral metabolism in pigs (aged 6 months) of Landrace and Kemerovskaya breeds reared and kept in large industrial complexes named β€œChistogorsky” and β€œAltaimyasoprom” (250 thousand heads in each) and to determine differences between two breeds in biochemical, hematological and mineral parameters. The Kemerovskaya breed belonged to local one but the Landrace breed was introduced from Ireland 3 generations ago. Concentrations of albumins, urea and phosphorus were higher in the Landrace breed then in the Kemerovskaya breed. In contrast, there was increased concentration of globulins and AST activity in animals of the Kemerovskaya breed in comparison with the Landrace breed. In addition, there were differences between breeds in some hematological indices and mineral metabolism parameters excluding phosphorus. The average population levels of the parametersinvestigated in two pig breeds could be used as reference values to evaluate animal’s interior at other pig farms in Western Siberia. The selected biochemical indices are recommended to farmers to assess the physiological status of animals in large industrial pig-raising plants

    The study aims to evaluate the influence of the ecological and geographical factors on the zinc content of light Hereford bulls and calculate the reference intervals for this metal. Lung samples weighing 100 g were taken from clinically healthy bulls of the Hereford breed in the Maslyaninsky, Novosibirsk and Krasnozersky districts of the Novosibirsk region and the Tselinny district of the Altai Territory. The chemical composition of lung tissues was determined by atomic absorption spectrometry with electrothermal atomization. The homoscedasticity of dispersions in groups was assessed using the Fligner-Keelin test. The influence of the factor was determined using the Kruskal-Wallisl test. Multiple intergroup comparisons were made using Dunn’s test and Holm’s correction. The maximum zinc level was found in animals bred in the Maslyaninsky district (26.6 mg/kg) and the minimum – in Krasnozersky (13.8 mg/kg). Cattle from the Maslyaninsky district are characterized by higher phenotypic variability in zinc content in the lungs than in other areas. Generally, the variability of the studied metal in the lungs of gobies is relatively low. Group variances in the zinc level in cattle lungs are homoscedastic (x2 =2.27; P=0.518). The influence of the ecological and geographical factors on the zinc level in Hereford cattle’s lungs was established (H = 12.158; P = 0.007). The concentration of metal in the lungs of bulls from the Krasnozersky district is statistically significantly different from cattle from Maslyaninsky (Z = -2.96; P = 0.009). There were no statistically significant differences in Zn concentration in lung tissues between animals from other regions. Reference intervals for the content of zinc in the lungs of Hereford cattle in the conditions of the south of Western Siberia are 12.44-24.12 mg/kg, with 90% confidence intervals for the lower limit of 10.15-13.66 mg/kg and the upper limit of 22.73 -26.49 mg/kg.ЦСль исслСдования – ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ влияниС эколого-гСографичСского Ρ„Π°ΠΊΡ‚ΠΎΡ€Π° Π½Π° содСрТаниС Ρ†ΠΈΠ½ΠΊΠ° Π² Π»Π΅Π³ΠΊΠΈΡ… Π±Ρ‹Ρ‡ΠΊΠΎΠ² гСрСфордской ΠΏΠΎΡ€ΠΎΠ΄Ρ‹ ΠΈ Ρ€Π°ΡΡΡ‡ΠΈΡ‚Π°Ρ‚ΡŒ рСфСрСнсныС ΠΈΠ½Ρ‚Π΅Ρ€Π²Π°Π»Ρ‹ для этого ΠΌΠ΅Ρ‚Π°Π»Π»Π° Π² Π΄Π°Π½Π½ΠΎΠΌ ΠΎΡ€Π³Π°Π½Π΅.

    It is necessary to assess the state of nitrogen metabolism to deepen control over the usefulness of feeding cattle and ensure prompt response to nutritional imbalances and diet adjustments. Nitrogen balance is a key indicator of cattle metabolism. The authors presented the results of determining the content and variability of indicators of nitrogen metabolism in Holstein cattle in Western Siberia. The object of the study was the bulls of the Holstein breed, obtained from four sires in the conditions of industrial livestock enterprises in the West Siberian region. The authors also studied the main indicators of protein and non-protein nitrogen metabolism (using Vector-Best reagent kits): total protein, albumin, globulin, urea, creatinine, and uric acid. It was found that the indicators of total protein, albumin, globulins, urea, and uric acid were within the generally accepted boundaries of the physiological norm for cattle. However, the albumin-globulin coefficient was below the norm, and the creatinine level was above the physiological norm. The content of urea and creatinine and the albuminglobulin coefficient were characterized by the highest rates of variability, which indicates the heterogeneity of this population sample of Holstein cattle in terms of the peculiarities of the course of protein metabolism. The authors did not reveal statistically significant intergroup differences in the content of total protein (p = 0.67), albumin (p = 0.23), globulins (p = 0.87), albumin-globulin coefficient (p = 0.96) and urinary acids (p = 0.31) using the Kruskal-Wallis test. However, the authors established the influence of the father on the level of urea (p = 0.049) and creatinine (p = 0.042) in the blood serum of the offspring. The analysis of the protein gram and the level of uric acid in the blood serum of the offspring did not reveal significant differences in the influence of the father while differences were established in the level of end products of protein metabolism - urea and creatinine.Для углублСния контроля Π½Π°Π΄ ΠΏΠΎΠ»Π½ΠΎΡ†Π΅Π½Π½ΠΎΡΡ‚ΡŒΡŽ кормлСния ΠΊΡ€ΡƒΠΏΠ½ΠΎΠ³ΠΎ Ρ€ΠΎΠ³Π°Ρ‚ΠΎΠ³ΠΎ скота ΠΈ обСспСчСния опСративности рСагирования Π½Π° ΠΏΠΈΡ‚Π°Ρ‚Π΅Π»ΡŒΠ½Ρ‹Π΅ дисбалансы ΠΈ ΠΊΠΎΡ€Ρ€Π΅ΠΊΡ‚ΠΈΡ€ΠΎΠ²ΠΊΠΈ Ρ€Π°Ρ†ΠΈΠΎΠ½ΠΎΠ² слСдуСт ΠΎΡ†Π΅Π½ΠΈΠ²Π°Ρ‚ΡŒ состояниС азотистого ΠΎΠ±ΠΌΠ΅Π½Π°.

    The results of studies of indicators of nitrogen metabolism in the blood serum of the descendants of four bulls at the age of 12-13 months are presented. The studies were conducted in the South of Western Siberia at Vaganovo OJSC on the livestock population of Holstein breed. The creatinine concentration in the blood serum samples of the sons was determined using a set of reagents from Vector-Best (Russia). In the regions of animal breeding, constant monitoring of water, soil, feed, animal organs and tissues is carried out. It was established that in the areas in which the studied breeds were bred, the content of macro- and microelements did not exceed the MPC. The level of serum creatinine in the examined animals on average for all groups of sons was 308.2 Β± 24.1 ΞΌmol / L, which exceeds the generally accepted valuesΒ  Β of this indicator. However, taking into account age and sex and breed characteristics, taking into account data on the overall health of the animals examined, information on the ecological well-being of the breeding zone, the results can be considered as reference valuesΒ  Β for healthy Holstein bulls in Western Siberia. It was shown that in the blood serum of the sons of some fathers, the creatinine content was 1.7 times higher (364.2 Β± 52.7 ΞΌmol / L) than in the descendants of other manufacturers (p> 0.95). A group of half-siblings was found, which were characterized by a low hereditary predisposition to creatinine content. Discovered differences in the creatinine content in the blood serum of sons reflect the differentiation of bulls and indicate genetically determined features of the functioning of the homeostasis system. In this case, most likely, there is a different ability of descendants to adapt to environmental and climatic conditions.Π˜Π·Π»ΠΎΠΆΠ΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ исслСдований ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»Π΅ΠΉ азотистого ΠΎΠ±ΠΌΠ΅Π½Π° Π² сывороткС ΠΊΡ€ΠΎΠ²ΠΈ ΠΏΠΎΡ‚ΠΎΠΌΠΊΠΎΠ² Ρ‡Π΅Ρ‚Ρ‹Ρ€Π΅Ρ… Π±Ρ‹ΠΊΠΎΠ²-ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄ΠΈΡ‚Π΅Π»Π΅ΠΉ Π² возрастС 12–13 мСсяцСв.

    In the article, the authors presented the main achievements and problems of developing dairy cattle breeding associated with selection and breeding work in the Novosibirsk region. It is necessary to solve the following tasks step by step for the purpose of the sustainable, progressive development of the industry and improvement of selection and breeding work with dairy cattle in the region: the creation of a regional/regional council for breeding work; organization of the Novosibirsk tribal union of dairy industry enterprises; formation of an assistant service based on the Novosibirsk State Agrarian University (NSAU) in cooperation with the Siberian Federal Scientific Center for Agrobiotechnologies of the Russian academy of sciences and JSC Novosibirskagroplem (RSIC – Regional Selection and Information Center); formation of a unified global database of breeding resources of the Siberian Federal District (SFD), the central regions of the Russian Federation, member countries of the EAEU (Eurasian Economic Union) using foreign data sources; development and implementation of an information and analytical system that allows you to automate selection and breeding work at the level of the economy, region, country/countries; automating the process of phenotyping of dairy cattle and improving the quality of the work of assessors (classifiers) of the exterior. The implementation of the tasks outlined will contribute to the consolidation of approaches at the regional level. It will lead to an increase in the quality of primary zootechnical accounting, which, in turn, will allow the assessment of the genetic potential of dairy cattle productivity, taking into account regional specifics, with high accuracy. It is expected that the result of such activities will be the development of appropriate domestic software tools for gaining technological sovereignty and ensuring the food security of the region and the country.ΠžΡΠ²Π΅Ρ‰Π΅Π½Ρ‹ основныС достиТСния ΠΈ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΡ‹ развития ΠΌΠΎΠ»ΠΎΡ‡Π½ΠΎΠ³ΠΎ скотоводства, связанныС с Ρ€Π°Π·Π²ΠΈΡ‚ΠΈΠ΅ΠΌ сСлСкционно-ΠΏΠ»Π΅ΠΌΠ΅Π½Π½ΠΎΠΉ Ρ€Π°Π±ΠΎΡ‚Ρ‹ Π² Новосибирской области.

    The purpose of this paper is to evaluate the primary databases of zootechnical records in western Siberia. The object of the study was the records on milk productivity (milk yield during the whole lactation, milk fat content, milk protein content, amount of milk fat, amount of milk protein), duration of lactation (service period, dry period, inter-breeding period), age of the first fruitful insemination and information on the origin of 20,000 Holstein cows. The validity of the raw data was assessed by assuming a Gaussian distribution without significant human influence. For this purpose, the Anderson-Darling test and corresponding visualization using histograms and quantile-quantile plots were applied. The list of traits of milk production was based on the values of the Anderson-Darling criterion. The authors found that the highest levels of this criterion were correlated with milk fat and protein. And the indicator Β«milk yieldΒ» was practically absent from the list of traits of dairy productivity. These results can be explained by the fact that in most enterprises, the value of milk yield was higher than the appraisal threshold values. An analysis of the genealogical trees of the studied breeding enterprises was carried out, along with the use of statistical criteria. This analysis revealed the inappropriate assignment of several dozen of offspring to a single mother. Thus, the presented approach can be used to identify outliers associated with human factors. And it can also be related to improper methodological support of the sampling process and errors in the work of the laboratories of selective milk quality control associated with the sampling and delivery of samples.ЦСлью настоящСй Ρ€Π°Π±ΠΎΡ‚Ρ‹ являСтся ΠΎΡ†Π΅Π½ΠΊΠ° Π±Π°Π· Π΄Π°Π½Π½Ρ‹Ρ… ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½ΠΎΠ³ΠΎ зоотСхничСского ΡƒΡ‡Ρ‘Ρ‚Π° Π² Π—Π°ΠΏΠ°Π΄Π½ΠΎΠΉ Π‘ΠΈΠ±ΠΈΡ€ΠΈ.

    The characteristic of bulls-producers of red breeds of OAO Barnaulskoe breeding enterprise on the quality of sperm and its resistance to cryopreservation are presented. The breeding enterprise has examined samples of water, soil, feed for the content of heavy metals. In the studied samples, no excess of the LOC was found. The research results were processed on a PC using population statistics methods. Angler bulls produced the largest amount of ejaculates unsuitable for cryopreservation. It is 20.6%. According to this indicator, they surpassed the producers of red Danish and red steppe breeds by 4.1-7.8%. The animals of the latter breed showed the smallest amount (1.7%) of ejaculates rejected after defrost. In Angler bulls, this indicator was 5.95%, in red Danish bulls it was 2.95%, which is 3.52 and 1.75 times higher than in red steppe breeders (P <0.01-0.001). Significant differences were established between individual bulls of the red steppe breed in the number of ejaculates rejected before cryopreservation (2.84-22.29%) and after defrost (0-7.09%). The differences between breeds in the frequency of rejected ejaculates before freezing and after cryopreservation indicate a certain role of heredity in the resistance of animals for these indicators. Spearman’s rank correlation coefficient between these traits was 0.312. It indicates the possibility of preliminary assessment and selection of bulls according to the first indicator. But the final assessment of the bull-producers can be made by the frequency of rejected ejaculates after thawing. We propose to consider the issue of additional accounting in breeding programs for the resistance of the seed of bulls-producers to cryopreservation.ΠŸΡ€ΠΈΠ²Π΅Π΄Π΅Π½Π° характСристика Π±Ρ‹ΠΊΠΎΠ²-ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄ΠΈΡ‚Π΅Π»Π΅ΠΉ красных ΠΏΠΎΡ€ΠΎΠ΄ ОАО ΠŸΠ»Π΅ΠΌΠΏΡ€Π΅Π΄ΠΏΡ€ΠΈΡΡ‚ΠΈΠ΅ Β«Π‘Π°Ρ€Π½Π°ΡƒΠ»ΡŒΡΠΊΠΎΠ΅Β» ΠΏΠΎ качСству спСрмы ΠΈ устойчивости Π΅Ρ‘ ΠΊ криоконсСрвации.

    The assessment of iron levels in cattle muscle tissue is crucial for livestock management because it influences both animal health and meat quality, key factors in sustainable development. This study aimed to develop an optimal model for noninvasively predicting the iron content in Hereford cattle muscle tissue, contributing to a comprehensive understanding of the animals’ elemental status. The research involved the atomic absorption analysis of muscle tissue and hair samples from cattle. A regression model was constructed using the least squares method to identify the most effective approach. These findings have ecological applications, aiding in evaluating environmental health and establishing acceptable iron thresholds for animals. The proposed mathematical model utilizing biomarkers (levels of Mg, K, Fe, Al, Cr in hair) will allow for the assessment of iron levels in cattle muscle tissue throughout the period of productive use, with the possibility of adjustment and tracking the changes in elemental status over time. The utilization of the developed method will enable the diagnosis of animal elementosis and assessment of the iron level burden. Subsequently, this will allow for the improvement of the qualitative characteristics of the final product. Thus, the obtained data contribute to fundamental knowledge regarding the content and variability of iron levels in the muscle tissue of cattle

    The authors found out average population levels of protein metabolism of the bulls aged 18 months. These parameters can be used as guide values for Hereford cattle in western Siberia. The paper speaks about positive correlations between biochemical parameters of protein metabolism and concentration of lead in muscles, spermaries, spleen, heart and lungs. The authors analyzed the organs and muscle tissue on lead concentration by means of atomic absorption spectrometry on spectrophotometer Shimadzu AA-7000. The researchers defined biochemical parameters on biochemical analyzer Photometer 5010. The authors assessed biochemical parameters of protein metabolism where concentration of crude protein, albumens, BUN, uric acid and creatinine was within physiological standards. The researchers observed positive correlations between the concentration of lead in lungs, muscles, spleen, spermaries and heart with parameters of protein metabolism.УстановлСны срСднСпопуляционныС ΡƒΡ€ΠΎΠ²Π½ΠΈ Π±Π΅Π»ΠΊΠΎΠ²ΠΎΠ³ΠΎ ΠΎΠ±ΠΌΠ΅Π½Π° Ρƒ Π±Ρ‹ΠΊΠΎΠ² Π² возрастС 18 мСсяцСв, ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Π΅ ΠΌΠΎΠ³ΡƒΡ‚ Π±Ρ‹Ρ‚ΡŒ приняты Π² качСствС ΠΎΡ€ΠΈΠ΅Π½Ρ‚ΠΈΡ€ΠΎΠ²ΠΎΡ‡Π½Ρ‹Ρ… Π·Π½Π°Ρ‡Π΅Π½ΠΈΠΉ для гСрСфордской ΠΏΠΎΡ€ΠΎΠ΄Ρ‹ Π² условиях Π—Π°ΠΏΠ°Π΄Π½ΠΎΠΉ Π‘ΠΈΠ±ΠΈΡ€ΠΈ.

    Ecological and climatic factors have an impact on the health, productivity and reproduction of the cattle. The goal of this work is the study of physiological status of servicing bulls reared under ecological and climate conditions of the Altai region, by defining the differences between Red-Steppe, Simmental and Black-and-White breeds in spermatogenic, hormonal, biochemical and hematological parameters. Samples of peripheral blood and ejaculates were taken from 48 grown-up servicing bulls (average age 5.6Β±0.3 years) in autumn period. It was established that Red-Steppe bulls have higher concentrations of nonorganic phosphorus, leucocytes, erythrocytes, hemoglobin, hematocrit and erythrocyte sedimentation rate in comparison with animals of Simmental breed, and the hemoglobin concentration and hematocrit are also higher in comparison with Black-and-White breed. It was noted that bulls of Black-and-White breed have a higher level of cortisol in comparison with the other breeds. The lowest level of serum urea and total protein and increased serum activity of creatine kinase and Ξ³-glutamyl transferase, as well as the heaviest body weight were observed in Simmental breed bulls. The differences between breeds in a wide spectrum of physiological measures reflect not only genetically determined peculiarities of homeostatic mechanism, but also may reflect different ability to adapt to local ecological and climate conditions of the Altai region. Spermatogenic, biochemical and hematological measures in bull sires reared in the Altai region were similar to those in bulls bred in other Russian regions and some other countries. The measures reported could serve as reference values and therefore represent β€˜normal’ values of physiological status for these bull sires reared in this ecological and climatic zone, but could be utilized in further studies for comprehensive monitoring of cattle breeding stock in other ecological and climatic zones of the Siberian region of Russia
