Opis:
CVM (Complex Vertebral Malformations) and Brachyspina (BY) are the most common autosomal recessive genetic defects occurring in the last two decades in Holstein dairy cattle around the world. Beginning from 2004 and 2014, 3035 and 338 Polish Holstein-Friesian bulls were tested to find carriers of CVM and BY, respectively. Among analyzed bulls 191 CVM carriers (6.29%) and 20 BY carriers (5.92%) were identified. No CVM carriers were observed beginning from 2016, whereas only single BY carriers was identified annually for the last 5 years. One bull turned to be double CVM/ BY carrier as a son of also double CVM/BY top Dutch sire (JABOT 90676-4-9). It is shown that CVM and BY defects are practically eradicated from Polish dairy cattle although incidental testing should be continued if new bulls with CVM or BY carriers in sire or dam pedigree will unexpectedly appear.

Opis:
Blood samples from forty-six roe deer (Capreolus capreolus) acquired during officially approved hunting in six hunting divisions throughout Poland were used to isolate the genomic DNA. All individuals were genotyped by MD_Bovine BeadChip (Illumina) for 46.750 Single Nucleotide Polymorphism (SNP) markers. SNPs of inappropriate clusters, with a marker call rate lower than 90% and with a minor allele frequency (MAF) lower than 0.01, located on sex chromosomes and mitochondrial DNA, were removed. Altogether, 21.033 SNP markers were included for further analysis. Observed and expected heterozygosity amounted to 0.098 and 0.119, respectively. Among 21.033 markers, a panel of 148 SNPs were selected for relationship analysis. They were unlinked and had a MAF higher than 0.2. This set of SNPs showed a probability of parentage exclusion of 1.29x10 -6 and 2.37x10 -19 for one, and two known parents, respectively. The probability of identity was estimated at 1.8x10 -40. The probabilities obtained in this study are sufficient for the monitoring and effective management of the genetic diversity of roe deer in Poland and is a cost-effective complementary tool for forensic applications.

Opis:
A salt-marsh assemblage of agglutinated foraminifera was recovered from a salt marsh on the east side of Tubli Bay in eastern Bahrain. This locality is one of the last remaining patches of salt marsh on the east coast of Tubli Bay. The salt marsh is covered by a single marsh plant species, Arthrocnemum macrostachyum. Samples were collected from beneath the Arthrocnemum canopy in two transects beginning at the maximum landward extent of halophytic plants in the high marsh and extending to a tidal channel at the seaward side of the low marsh. A distinct elevation-related zonation in foraminifera is observed from the high marsh to the low marsh. The trochamminids Entzia macrescens and Trochammina inflata are characteristic of the high marsh, whereas Ammonia, Elphidium, Peneroplis and smaller miliolids become common in the middle part of the marsh transect. The tidal channel at the lower limit of the marsh contains an assemblage dominated by Ammonia, Elphidium, adult specimens of Peneroplis, and smaller miliolids, with Clavulina and Agglutinella as the only agglutinated taxa. Living specimens of Entzia and Trochammina were observed during the winter 2019–2020 sampling season, whereas samples collected in Autumn 2019 contained only dead specimens. One new species, ?Sigmoilina canisdementis sp. nov., is described herein. This is the first report of a live Entzia-dominated salt marsh assemblage in the Arabian Gulf region.

Opis:
The aim of this study is to compare the corrosion resistance of X37CrMoV5-l tool steel after nanostructurization and after a conventional heat treatment. The nanostructuring treatment consisted of austempering at 300°C, which produced a microstructure composed of nanometric carbide-free bainite separated by nanometric layers of retained austenite. The retained austenite occurred also in form of blocks which partially undergo martensitic transformation during final cooling. For comparison, a series of steel samples were subjected to a standard quenching and high tempering treatment, which produced a microstructure of tempered martensite. The obtained results showed that the corrosion resistance of steel after both variants of heat treatment is similar. The results indicate that the nanocrystalline structure with high density of intercrystalline boundaries do not deteriorate the corrosion resistance of steel, which depends to a greater extent on its phase composition.

Opis:
In the present study, the effectiveness of a mixture of silver nanoparticles with polyhydric alcohols (glycerol, erythritol, mannitol and xylitol) against six species of healthpromoting bacteria have been examined. Synthesis of silver nanoparticles was carried out using trisodium citrate as the reducing and stabilizing agent. The nanoparticles were characterized by electronic absorption, scanning electron microscopy and powder X-ray diffraction measurements. Electronic absorption spectrum revealed high uniform of synthesized nanoparticles. Practically no aggregation was observed when nanoparticles were mixed with polyhydric alcohols, suggesting weak interaction between ingredients of the mixture. Spherical silver nanoparticles, as depicted by scanning electron microscopy, were found to have diameters in the range of 10 to 30 nm; mean diameter was 18 ± 4 nm. The X-ray diffraction pattern of the prepared samples indicated the face-centred cubic crystalline structure of the metallic silver nanoparticles. In biological study, quite interesting protective effect of polyalcohols on the growth inhibition of health-promoting bacteria by silver nanoparticles was observed. The most substantial protective effect of the tested silver nanoparticles-polyalcohol mixtures was estimated for B. bifidum, L. paraplantarum, and L. phamnosus species.

Opis:
The aim of this study was to investigate the effect of PAF supplementation in semen extender on ATP content in cryopreserved bull spermatozoa used for artificial insemination at different time intervals. Cryopreserved semen was treated with different concentrations of PAF: 1x10⁻⁵M, 1x10⁻⁶M, 1x10⁻⁷M, 1x10⁻⁸M and 1x10⁻⁹M at 37°C. In the present work we showed that content of ATP in cryopreserved semen supplemented with 1x10⁻⁹M PAF was statistically significantly higher at 90 and 120 minutes of incubation in comparison to the control group (p≤0.05). Present study indicates the potential influence of PAF on ATP content in male spermatozoa via it’s protective role towards mitochondria metabolic activity.

Opis:
The aim of this study was to evaluate the effect of C/T missense mutation (SOX5) gene on selected parameters of non-frozen semen in Polish Holstein – Friesian bulls. Three hundred and sixty eight bulls were genotyped by the PCR-Rsa I technique. Semen was collected and evaluated by standardized procedure used in an AI station. Significant associations were found between SOX5 genotypes and sperm concentrations (p=0.020) and sperm motility (p=0.014). Bulls with TT genotype had the lowest values of both traits. Our results demonstrate that C/T missense mutation within the SOX5 gene is involved in bull sperm quality.

Opis:
The aim of the study was to find out whether carriers of new genetic defect Cholesterol Deficiency (CD) occur in the population of Polish Holstein-Friesian bulls. Twenty seven bulls were included in the analysis. Bulls were selected as having in the pedigree known carrier of CD (Maughlin Storm CANM000005457798). All bulls were diagnosed by the test described by Menzi et al. (2016) by using allele-specific PCR. Among 27 bulls, 9 new CD carriers were found. Our results show that causal mutation for CD is already transmitted to Polish Holstein-Friesian cattle. The results are sufficient ground to take practical action in order to avoid further spreading of mutation causing CD.

Opis:
The object of the research is a technological process and technical means of cutting woody shrubs at melioration objects. The subject of the research consists of regularities and methods of execution of the process of cutting woody shrubs at melioration objects by a multirotor mower with trapezoidal knives. The aim of the research is to increase efficiency of cutting shrubs at melioration objects by applying a multi-rotor mower with trapezoidal knives. We have obtained analy tical dependences in order to determine the angle of diversion of a knife from the radial position during contact with the stem, and to calculate the reaction in the joint “knife-fixing bolt” depending on the parameters of a knife and rotor, and the distance from the centre of the knife fixing bolt to the point of contact of a knife and stem, which provides minimal impact load on the knife fixing bolt during cutting woody shrubs. We have also developed a mathematical model of the process of cutting shrubs by a multi-rotor mover with trapezoidal knives, and methods of determination of the main parameters and regimes of work of the mower cutting apparatus for cutting shrubs at melioration objects, which contain a monogram, based on the use of theoretical-experimental dependences.
Celem pracy było opracowanie technologii koszenia roślinności na glebach odłogowanych i obiektach melioracyjnych, a także zwiększenie efektywności pracy wielobębnowej kosiarki z nożami trapezowymi. Rozważania teoretyczne prowadzono na bazie praw mechaniki, natomiast doświadczenia z wykorzystaniem specjalistycznej aparatury oraz metod obliczeniowych. Określono między innymi zależności analityczne na kąt odchylenia noża od położenia radialnego, reakcję w przegubie (nóż-sworzeń) w zależności od parametrów geometryczno-kinematycznych. Opracowano metodykę wyznaczania podstawowych parametrów pracy nożowego zespołu tnącego. Sporządzono nomogram wyznaczania podstawowych wartości parametrów eksploatacyjnych oparty na teoretyczno-eksperymentalnych zależnościach. W pierwszym kwadracie monogramu są linie prędkości postępowej kosiarki, w drugim – linie kąta zaostrzenia tnących ostrzy, w trzecim linie prędkości kątowej bębna, w czwartym – linie kąta rozwarcia tnących ostrzy.
