The basis of genetic diversity is its genetic component. The loss of native species and breeds of cattle is a real threat to the biosphere, as the resilience of natural ecosystems and agroecosystems is directly linked to their genetic ability to adapt to environmental conditions. Polymorphism of ISSR-markers of the Ukrainian population of water buffaloes (Bubalus bubalis) from the farm of “TASBIO” LLC (Chernihiv region) was analyzed in 66 animals selected for the study. Genomic DNA samples were isolated from venous blood with a standard set of reagents. Genotyping was performed using specific ISSR primers: (ACC)6G, (GAG)6C, (AG)9C, (CTC)6C, (AG)8CA, (AG)8CGand (GA)6CC. We determined the difference in spectra both by the number of amplicons, their lengths (number of nucleotides) and by their polymorphism. As a result of the study, all primers showed polymorphism of buffalo DNA regions. Amplicons were defined in the range from 200 bp up to 4000 bp. Analysis of ISSR spectra revealed 87 loci, of which 71 were polymorphic. (AG)8CA-marker was the least polymorphic (PIC=0.234), (CTC)6C the most polymorphic (PIC=0.389). Conservative loci were found in four ISSR markers: 6 in (AG)8CA marker, 5 in (AG)8CG, 4 in (GA)6CC, and 1 in (AG)9C. 67 species-specific loci were identified for the Ukrainian water buffalo population: 10 for (AG)9C, 3 loci for (ACC)6G, 4 for (GAG)6C, 7 for (CTC)6C, 15 for (AG)8CA, and 14 in (AG)8CG and (GA)6CC. The ISSR primers used are recommended for molecular genetic analysis of buffalo DNA polymorphism.","PeriodicalId":22372,"journal":{"name":"The Animal Biology","volume":"241 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74529024","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 studies were conducted at four photoperiod points: winter (January), spring (March), summer (July), and autumn (October). Lower levels of oxidative stress biomarkers (P<0.05) were observed in the younger rats when compared to older rats, as well as in HR rats compared to LR rats. The levels of lipid peroxidation end product, 2-thiobarbituric acid reactive substances (TBARS) as the major indicator of oxidative stress, were found to increase with age, and summer resulted in further elevation compared to other seasons. Also, oxidative stress biomarkers were lower (P<0.05) in winter than in other seasons, especially in the HR rats. TAC level in the hepatic tissue of the 6 months aged rats was significantly higher (P<0.05) elevated when compared to older rats. A similar higher TAC level was in the hepatic tissue of HR rats compared to the LR rats. The adult rats with HR maintained TAC with minimal fluctuations throughout the year. It should be noted that the difference in TAC was higher for the groups of the adult animals with HR in winter, spring, and summer, which may indicate effective mechanisms preventing the formation of reactive oxygen species and systems of elimination thereof.","PeriodicalId":22372,"journal":{"name":"The Animal Biology","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78599629","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 areas of its solution today is the use of organs and tissues of animals — xenotransplantation. Pigs for medical and biological needs must be stress-resistant and adapted to the conditions of keeping and feeding within the vivarium. Stress syndrome in pigs is caused by a point mutation that replaces 1843CT in exon 17 of the ryanodine RYR1 receptor gene in a homozygous state. The aim of the study was to examine the genetic structure of individual pig populations at the locus of the RYR1 gene responsible for hypersensitivity. DNA testing of 102 pigs of Poltava meat, Myrhorod, Great White, Landrace and Pietren breeds was performed. The studies were performed on DNA samples obtained from pig blood. DNA was isolated using Chelex 100 reagent. Studies of the RYR1 gene fragment were performed by restriction fragment length polymorphism (RFPR) by polymerase chain reaction (PCR). Two alleles of the ryanodine RYR1 receptor gene (n and N) and three genotypes (NN, Nn, nn) were identified in the studied animals. A molecular study of pigs of different breeds revealed a polymorphism of the RYR1 gene. The number of animals carrying the recessive allele n of the ryanodine receptor gene RYR1, which is responsible for the sensitivity of pigs to stress factors, varied considerably: from its complete absence in the Vietnamese Pot-bellied, Ukrainian meat, Large White and Ukrainian Spotted Steppe breeds up to 100% of animals of homozygous RYR1nn genotype in the Piétrain breed and 50% of Landrace individuals with the heterozygous RYR1Nn genotype The mutant RYR1n allele was found in animals of the Piétrain breed with a 100% frequency. Heterozygous genotype RYR1Nn was found in pigs of Poltava Meat (10%), Landrace (50%), Myrhorod (15%) Ukrainian Spotted Steppe (50%). Homozygous RYR1NN genotype was detected in all Large White, Vietnamese Pot-bellied, and Ukrainian Meat pigs studied, indicating the absence of stress syndrome. It has been established that pigs of the Great White, Vietnamese Pot-bellied, and Ukrainian Meat breeds are preferred for breeding for biomedical purposes. Breeding of Piétrain pigs and any combinations with this breed makes it impossible to use such animals for biomedical experimental work.","PeriodicalId":22372,"journal":{"name":"The Animal Biology","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83866606","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}

Zubets NAAS for eight years. The sperm suspension was thawed in a water bath at +37 °C for 5 min until completely thawed. Separation of sperm from cryopreservative agent and diluent was performed using the swim up method in Sp-TALP medium. After the presence of sperm in the 10.0% solution of PVP for 10 min, motility decreased by 68.2% (P < 0.05) and amounted to 3.4%, and after the next 10 min of incubation decreased to 1.4% (P <0.01), which is 10 times lower than the initial mobility. In 10.0% of PVA mobility after 10 min of incubation decreased by 37.4% (P <0.05) and amounted to 6.7%, and after 10 min decreased to 5.7% (P < 0.01), which is 1.8 times lower than the initial mobility. It was found that in the case of 10.0% of PVP solution ejaculated deconserved boar sperm lose motility by 86.9% (P <0.01) from the initial motility, which makes it impossible to select a suitable sperm for fertilization by ICSI (intracytoplasmic sperm injection). It is shown that 10.0% PVA solution can be used for immobilization of boar sperm, as it reduces motility by 46.7% (P <0.01) of the initial sperm motility.

With an integrated approach to the production of chicken meat, it is possible to increase the productivity of poultry enterprises, energy efficiency and reduce the cost of production. When applying such an integrated approach, one of the important roles is played by the provision of high-quality disinfection with effective and inexpensive means. In connection with the relevance of the development of new effective disinfectants, the main purpose of the research was to determine the effectiveness of working solutions in concentrations of 0.1; 0.2; 0.25 and 0.5% for gram-negative E. coli ATCC 25922 and gram-positive S. aureus ATCC 25923 for different periods of time — 20, 30, 60 and 120 min. after the simulation of protein contamination.

The tagmospecific response of the antioxidant system of honey bees depending on the wintering temperature was revealed. Keeping bee colonies indoors at constant temperatures (for ten weeks) was accompanied by certain coherence in the work of the antioxidant system of insects.
