- The aim of research was analysis of the results in range of growth and slaughter performance of gilts and young boars kept and performance tested in the area of Pomorze and Kujawy in years 2007-2015
- Aim of study was to investigate behavior of donor and recipient PGCs by 1. isolation method of gonadal PGCs from 28-29 (H&H) stage donor embryos to obtain possible highest number of non-aggregating cells; 2. examination of migratory capabilities of PGCs derived from Ross 308 and green-legged partridgelike in the role of donor or recipient of cells; 3. elaboration a new method of partial sterilization of recipients using cytostatic- terosulfan (TERO)
- The aim of the doctor's thesis was to investigate transformations of selected UV filters under the influence of radiation, oxidizing and chlorinating agents and identification of transformation products. The subject of interest was also the ecotoxicological evaluation of UV filters and their degradation products
- The aim of the paper was to assess the changes in the value of selected production and functional traits of dairy cattle after the introduction of the automatic milking system (AMS)
- The aim of the PhD thesis was to synthesis of inorganic phosphors based on tungstates and molybdates, doped with selected luminescent ions (III), and characterization of their photophysical i.e. morphological, structrural and luminescent properties
- The aim of the present study was to evaluate the frequency of CAST and CAPN3 alleles and genotypes in three Polish sheep ( Kamieniecka, Pomeranian, Coloured Polish Merino) breeds from three flocks kept in three voivodships. In addition, the aim was to find associations between calpastatin, calpain3 genotypes and meat performance traits in the studied groups of animals
- The aim of the present was to identify polymorphism within the genes: RYR1, AREG, EGN, SPP1, GH, GH-RH, PIT1, BF, ZAR1 and to determine their genetic structure in two Polish sow breads: Polish Landrace and Polish Large White breeds. In addition the aim was to find associations between polymorphism of selected genes and reproductive traits in the studied groups of animals
- The aim of the research is to assess the impact of anthropopression caused by the functioning of land for soils of the selected area of the Grudziądz Basin
- The aim of the research of this dissertation has been to determine the role of phenolic compounds in the processes of transformations of organic matter of meadow soils leading to the formation of humus substances
- The aim of the research was to assess the effectiveness of the use of data from periodic control of dairy utility in the selection of cows with energy metabolism disturbances and the impact of their delay in the first insemination on the reproductive indicators of the herd
- The aim of the research was to produce a product that could replace, partially or completely, peat in plant conditioners, peat in agents improving soil properties as well as peat in beddings for cultivation of garden plants
- The aim of the study was determine the influence of polymorphism selected genes on milk yield and percentage of protein, fat and dry matter content in Holstein-Friesian cow`s milk which were kept in two herds in Kuyavian and Pomeranian province. The kappa-casein genne, the betalactoglobulin gene, the growth hormone gene and the prolactin gene were analysed in the experiment. the examined features were analysed in terms of the housing system and the lactation order
- The aim of the study was to assess the quality of eggs, slaughter value and meat obtained from poultry fed with compound feed containing lupine seeds
- The aim of the study was to determine the morphological composition of eggs and to analyse the development of embryos. Biological analysis of hatching and evaluation of the post-embryonic development of goslings were performed
- The aim of the study was to determine whether PIT-1/HinfI, GHRH/BsuRI, GH/AluI, IGF-1/Eco105I gene polymorphism influances the value of milk traits. The analyzes were as follows: mean daily yield, percentage of fat, protein, lactose, dry matter and urea content and number of somatic cells. The above characteristics were analyzed according to the following factors: lactation order and maintenance system
- The aim of the study was to effects of feeding on growth, carcass composition and meat quality in ducks
- The aim of the study was to evaluate meat traits in Pekin ducks of strains P-33 ( Polish Pekin), P-8 ( Danish Pekin) and P-9 ( French Pekin) covered by the genetic reserve conservation programme in Poland
- The aim of the study was to evaluate the impact of genotype, hen age, egg storage duration, type of setter and type of on embryo mortality, hatchability and chick quality
- The aim of the study was to examine the mechanisms of higher anti-fungal activity in perennial ryegrass inhabited by E. festucae var. lolii, associated with the presence of pathogenesis-related proteis and phenolic compounds. Additionally the level of inhabitation was assessed, other endobiotic fungi were identified, and the antifungal activity of selected isolates was assessed in vitro and in vivo
