The present review attempts to sum up the knowledge concerning the effect of dry period length on the milk yield of cows in the next lactation. The dry period is characterized by radical changes in the anatomy, histology and physiology of the mammary gland, which undergoes the stages of active involution, steady state, and colostrum production. The 60-day dry period, once considered optimal, was adopted...
The aim of this work to determine the effect of superabsorbent Aqua–Gel P4 on the dynamics of lawns emergence. The experiment was established in 2007. The studies were carried out on the base of two lawn experiments. The first experience was a monoculture lawn where in pure sown four species of lawn grasses were studied. In the second experiment four designed mixtures of the same grass species were...
Currently in the natural environment tigers live in areas of eastern Turkey, through southern Asia to southeastern Siberia, Malay Peninsula and Sumatra, Java and Bali. Generally, the area of occurrence of these predators declined and some subspecies extincted, for example Javanese tiger, Balinese tiger, the Caspian tiger. Zoos are therefore still places where you can see live the big cats. They are...
Soil material collected for Part I, Stratigraphy, chemical properties, including macroelements of industrisols (initial and humus) within Peninsula Ewa in Szczecin Port was used for determining the concentration of heavy metals: Cd, Pb, Zn, Cu, Ni, Co, Mn and Fe in these soils. The studies showed that the soils sealed with reinforced concrete slabs, in their surface layer 0.25–1.50 m, on a small area,...
Francis Bacon’s renaissance idea of alleviating the suffering of patients contributed to the creation of the concept of euthanasia and its evolution over the ages with the following change of moral and ethical attitudes in human and veterinary medicine. In the 21’st century there is an ongoing controversy around the legalisation of euthanasia in people terminally ill. On the other hand the quality...
The studies included initial industrisols (ecranic) on the peninsula Ewa in Szczecin port. Samples of these soils were collected from deep boreholes (to 13 m below ground level), whereas those of humus soils from the topsoil 0–25(30 cm) of sporadically occurring lawns. Port infrastructure did not allow sampling deeper strata. In stratigraphic structure of initial ekranosols, the surface layer, 2.7–4...
Wine producers have been working on selecting the most suitable grape variety for specific regions and therefore improving wine production technology for numerous years. Climate changes lead to change in grape quality; in the future these changes will have to be considered by the vineyard owners as they will affect cultivation methods, harvest dates and vinification process. The aim of this paper...
The aim of the studies in the years 2009–2010, carried out in the climate conditions of Szczecin, was to compare the morphological traits, the course of flowering and the increase in number and weight of bulbs of four species: Arabian starflower (Ornithogalum arabicum L.), Sun star (Ornithogalum dubium Houtt.), Giant Chincherinchee (Ornithogalum saundersiae Bak.), and Chincherinchee (Ornithogalum...
