UBT International Conference

Raspberries fruits (Rubus idaeus L.) as important part of our diet are known for their sensory and nutritional characteristics, because of high content of essential nutrients that are beneficial for biological activity in human health. A high consumption of plant foods, such as raspberries, appears to decrease the risk of obesity, diabetes, heart disease, and overall mortality. It can also promote a healthy complexion, increased energy, and overall lower weight. Nutritional quality was analyzed through by chemical parameter of fresh raspberry samples from plantation in Kosovo area at the ripe stage. The following quality parameters were determined in the raspberry’s …

Cholesterol Analysis By Enzymatic Method In Conventional, Pastured And Organic Eggs, Valon Durguti, Medin Zeqiri, Fjolla Vllasaliu

UBT International Conference

The concentration of cholesterol in three types of eggs has been analyzed through the enzymatic method. The types of analyzed eggs were: conventional, pastured and organic. Thirty five samples were analyzed, the sampling has been random, and the cholesterol analysis was done by GENESYS 10S UV-Vis Spectrophotometer. Analyzes have been conducted in research laboratories of the University for Business and Technology (UBT) - Kosovo. The average of the obtained results indicates a slightly lower cholesterol concentration in the type of pasture raised eggs compared to other types.

Parasite Fauna In Common Carp (Cyprinus Carpio L., 1758) From Cage Culture System On Tikvesh Reservoir (Macedonia), Dijana Blazhekovikj Dimovska, Stojmir Stojanovski

UBT International Conference

Parasites found in freshwater fishes are primarly protozoans, myxozoans, helminth (platyhelminths, nematodes and acanthocephalans), hirudineans and crustaceans. Although both ectoparasites and endoparasites are common in fishes, internal parasites are able to cause much greater damage to their hosts than external parasites.

Over the years, cage culture has become one of the economically viable methods of large-scale production of high-value food fishes. Although, cage farming has many economic advantages, diseases are one of the major limiting factors to the successful production.

The aim of this study was to determine the presence of parasite fauna in common carp (Cyprinus carpio L. …

Optimization Of The Ground For Cab 6p (Prunus Cerasus), Avdirrahman Gashi, Sami Gashi, Taulant Mitrushi, Edlira Kukali

UBT International Conference

Rooting is a process that is induced by many difficulties, especially in fruit trees. For this reason, four nutrient terrains that contain different concentrations of auxin ANA (α-naphthaleneacetic acid), BAP, GA3 and macro and micronutrient MSs are compared. Rizogenesis is observed after three to four weeks of cultivation on the ground of rupture. Explants react differently in each field used (Figures 4,5,6,7). The concentration of inorganic and auxinous ANA salts on the nutrient terrains affects the rooting index and the characteristics of the roots. Plants of the prunus cerasium L species showed better results during rooting cultivation I, where the …
