However, the intensive pace of development in poultry farming leads to several problems; one of the most important among them is the need to dispose of poultry waste. Large poultry farms can produce up to 100 thousand tons of manure annually, which belongs to the 3rd class of environmental hazards. Recycling manure allows enterprises to avoid penalties and receive additional economic benefits from selling organic fertilisers. Mechanochemical methods are one of the most accessible and effective ways to process livestock waste. Their essence lies in using chemical reagents for disinfection and processing raw materials.   The object of the study was a new drug with the properties of a growth stimulant, antidepressant, and antistressant obtained by mechanochemical processing of dry bird manure in an acidic environment.   The safety parameters were analysed in two accredited laboratories: agrochemical and veterinary. The agrochemical laboratory studied such indicators as the mass fraction of dry and organic matter, the activity of hydrogen ions (pH), the mass fraction of nutrients, the content of toxic elements and the presence of radionuclides. The veterinary laboratory analyses included such groups of indicators as parasitic cleanliness, sanitary-bacteriological, and sanitary-parasitological indicators. It has been shown that the leading indicators of the quality and safety of the drug in the working solution meet the requirements for organic fertilisers. For the medication to work effectively, when preparing a working solution, the consumer must strictly follow the instructions and observe safety precautions when working with a substance with a low pH level.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"31 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139529733","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}

Carp fingerlings were raised in the ponds with a stocking density of 34.77 and 57.73 thousand/ha. During the growing period, carp fingerlings were fed 5000 kg of feed mixture in equal parts of crushed barley and wheat grains. The species composition of zooplankton in the studied reservoirs is monotonous and is represented by nine species. Variable species diversity was observed in all reservoirs. The number of zooplankton in July in ponds No. 5 and No. 2 was 76344.45 and 48311.11 ind./m3, in August – 56800 and 48616.67 ind./m3; biomass – in the range of 2724.88-5777.86 and 1618.65-2258.73 mg/m3, respectively. Analysis of variance showed a relationship between the mass of under-yearlings and zooplankton biomass. It is 0.70, which indicates that the mass of carp under-yearlings increases with an increase in zooplankton biomass. The identified differences in the rates of linear growth and weight depending on the stocking density make it possible to establish fish productivity - in pond No. 2. It was 806.4. In pond No. 5 - it was 878.4 kg/ha. Planting 37.33 ind./ha is more productive and gives better growth indicators (average length and weight of carp fingerlings at the end of the study are 10.91 cm and 26.96 g, respectively) than planting 57.77 ind./ha (average length and weight at the back of the study 9.70 cm and 18.67 g, respectively). The planting density of 37 thousand specimens/ha makes it possible to grow fingerlings with a standard weight of 25-26 g. The influence of the stocking density factor on the weight of fingerlings is 0.92 (at a level of P > 0.001). Fish productivity in Pond No. 2 was 806.4 kg/ha, and in Pond No. 5, it was 878.4 kg/ha.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139622831","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}

One of the promising technologies is the bioconversion of organic waste by Hermetia illucens larvae or Black Soldier fly (BSF) larvae. BSF larvae can transform low-value raw materials into protein-and fat-rich entomological biomass, which can be used as raw material to produce feed for livestock, poultry, and aquaculture. To improve this technology and increase bioconversion efficiency, research into the selection of optimal feed rations for BSF larvae is necessary.   This study aims to analyze the effect of high-protein experimental diets fortified with fish meal (FM) on protein and fat accumulation in larvae, entomological biomass growth, and larvae’s growth rate in achieving the pre-pupal stage.   As part of the experiment, dieting wheat bran with different fish meal contents (5 %, 15 %, 30 %) was modelled, and a diet consisting of wheat bran was used as the control diet (CD). Larvae were also reared on a standard diet, chicken feed (CF), for comparison. The results indicate that larvae reared on CF observed the maximum entomological biomass growth rate. The highest protein content in larvae was found when insects were raised on high-protein diets with fish meal at 15 % and 30 % and was 53.31 ± 0.67 % and 54.33 ± 1.02 % in dry matter, respectively. The highest fat content was found on the control diet fed without protein supplement – CD (41.57 ± 1.75 %). The larval development rate on the modelled diets was assessed on the last day of the experiment by the number of pre-pupae. The highest number of pre-pupae was obtained on FM 15 % and FM 30 % and was 13.38 ± 3.42 % and 11.52 ± 3.87 %, respectively. The highest feed conversion BER (Bioconversion Efficiency Rate) was 33.29 ± 3.54 % at CF. Proteins and carbohydrates are the most significant nutrients when modelling feed rations.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621309","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 analysis of the causes of unprecedented losses of Apis mellifera L. bee colonies has been carried out. When using plant protection products in agrocenoses. The current state of knowledge on assessing the impact of pesticides on non–target objects is summarised as honey bees and other types of bee pollinators of plants. The mechanisms and features of selective exposure of insecticides from the group of neonicotinoids, butenolides and based on fipronil are described. In addition to direct lethal effects, there is a decrease in the viability and subsequent death of bee colonies as a result of changes in the cognitive abilities of worker bees, the reproductive potential of queens and drones, changes in the immune status of bee colonies and the etiological characteristics of insects. Examples of the negative impact on honeybee populations of various regions of the Russian Federation when using pesticides in agrocenoses are given. The role of organic agriculture in the conservation of honey bees and other pollinators, providing a yield comparable to the integrated plant protection system of entomophilic crops, is noted. Measures to prevent the reduction of honey bee populations due to pesticide toxicosis are outlined: 1. Compliance with the requirements of regulatory documents; 2. Providing apiaries with an optimal feed base; 3. Exclusion of highly toxic insecticides from entomophilic crop protection programs; 4. Realisation of the adaptive potential of honey bees in changing environmental conditions; 5. Transition to organic farming in the cultivation of entomophilic crops.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621939","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}

As a result, pathogenic microorganisms develop antibiotic resistance, which creates the need to either increase their dosage or replace them with other medications. Phytobiotics are a promising alternative to antibiotic drugs. Phytobiotics are active substances of medicinal plants that exhibit antimicrobial properties against pathogenic microorganisms. The primary sources of antimicrobial activity of phytobiotics are phenolic and polyphenolic compounds. The research aimed to study the antimicrobial activity of oregano (O) extracts and marsh cinquefoil (MC). Alcohol extracts (AE) were prepared from dry raw materials by water-alcohol extraction, and then alcohol-free extracts (AFE) were obtained using vacuum distillation. The content of polyphenolic compounds was studied in the obtained extracts, and the hole method against pathogens such as Staphylococcus aureus, Escherichia coli and Salmonella enterica evaluated their antimicrobial properties. The results showed that in O AFE, the content of polyphenolic compounds was 1.487 mg/ml, in O AE 1.166 mg/ml, in MC AFE 1.349 mg/ml, and MC AE 1.074 mg/ml. All studied extracts showed antimicrobial activity against Staphylococcus aureus. The most significant zones of suppression (1.86 cm) were formed around the wells with O AFE, which were significantly (P<0.01) larger than in the samples with O AE. About gram-negative cultures, zones of suppression were found only in alcoholic extracts, which is most likely a demonstration of the antibacterial activity of ethanol.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139622006","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}

More often, childbirth proceeded normally (easy), without outside intervention - 91.36 %, mild and moderate pathology was observed in 3.35 and 4.41 % of cows, and in rare cases, calving was accompanied by severe pathology - 0.87 %. The severity of the birth process increased with a decrease in the duration of the dry period. Thus, in animals with easy labour, the dry period was 54.73 ± 0.27 days; in animals with severe pathology, it was three days less - 51.74 ± 1.33 days. In cows with mild labour, the birth of one calf was more often observed; the number of twins did not exceed 8.95 %. The severity of labour was accompanied by an increase in the number of twins; in the group of animals with arduous labour, it reached 84.21 %. With a problematic labour process, the frequency of stillbirths in groups increases by 4.41 %. Animals with difficult births have an increased risk of obstetric and gynaecological pathology. Thus, in cows with a severe course of the birth process, in 26.32 % of cases, pathology of the third stage of labour was observed, accompanied by retention of the placenta. In the postpartum period, postpartum paresis was often recorded - 42.11 % and various types of metritis - 21.05 %. In contrast, with a mild course of labour, all the pathologies we studied were recorded in aggregate only in 29.35 % of cows.

It has been established that, regardless of which trait is taken as the base one, the bulls of the selection group exhibit highly productive qualities. Analysis of correlation coefficients allows us to note a strong connection between live weight and average daily gain, feed costs, assessment of meat qualities, relative gain, and the “A” index. A comparative evaluation of stud bulls based on the quality of their offspring indicates that the sons of Zaur 70099, Pankrat 6809, and Simons 6633 are improvers. When assessing the genealogical structure, the best indicators are shown by bulls belonging to the line of Castle 3335. When comparatively evaluating the strength of the influence of the line and the sire bull on the variability of traits, it was established that the stability of the impact of the sire bull is, as a rule, higher than the influence of the line and for the most critical traits it is more than two times. The highest power of the sire’s influence is noted for such characteristics as live weight, average daily gain, assessment of meat qualities, and complex index “A”. The population of the Kazakh white-headed breed has a high selection potential in assessing animal gene pool and phenol. Also, it has an optimal level of genetic variability of traits, expressed through the strength of the sire’s influence on the variability of traits.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139623234","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}
