    The effect of storage conditions and packing materials on the quality properties of chicken eggs
    (Estonian University of Life Sciences, 2024) Kryeziu, A.J.; Ramadani, Xh.; Hajra, L.; Kamberi, M.; Zogaj, M.
    This study investigated how storing eggs in different packaging (unpackaged eggs-control, cardboard, styrofoam, plastic) and temperatures (4–6, 20–22 °C) for 28 days affects their quality. Eight eggs were analysed on days 0, 7, 14, 21, and 28 for each treatment. Storage temperature–ST, packaging material–PM, storage duration–SD, and their interaction encouraged egg weight loss–EWL (P ˂ 0.05). The interaction of the three factors showed no significant difference in the EWL. Storage temperature significantly influenced (P ˂ 0.05), eggshell thickness–EST, albumen index–AI, albumen pH–ApH, Haugh unit–HU, yolk height–YH, and yolk index– YI. Some parameters like egg weight–EW g, shape index–SI and albumen weight–AW g, changed significantly (P ˂ 0.05) according to storage in different PM. The SI, eggshell weight–ESW g, EST, eggshell index–ESI, albumen ratio–AR, AI, ApH, HU, yolk weight–YW, yolk height–YH, YI, yolk colour–YC, and yolk:albumen–Y:A ratio changed during storage. The ST×SD was significant for EW, ESW g, EST, AW g, albumen ratio–AR, AI, ApH, HU, YW g, YH, and YI (P ˂ 0.05). As a result of the PM×SD interaction, significant differences (P ˂ 0.05) were observed in EW g ESW g, EST, AW g, and YI. A significant interaction effect of ST×PM×SD was found on AI, YH, and yolk pH–YpH (P ˂ 0.05). The purpose of this research is to give an overview of the storage conditions in order to have good quality eggs.

    Influence of altitude and lactation period on composition and physical properties of milk in crossbred Sharri sheep
    (Estonian University of Life Sciences, 2023) Ramadani, Xh.; Kryeziu, A.; Kamberi, M.; Zogaj, M.
    The aim of this study was to compare the changes in chemical composition and physical properties of raw milk from crossbred ‘Sharri’ sheep as a function of altitude (1,200 m - variant A and 1,600 m - variant B) and lactation period. Milk composition (total solids - TS, milk fat–MF, solids non-fat-SNF, protein - P, lactose - L, ash, freezing point - FP, titratable acidity - TA, active acidity - AA, and density - D) were analysed once per month during the period of June, July, August, and September of 2021. Sheep milk at 1,600 m altitude showed significantly higher values (P < 0.05) for all analysed parameters and lower values for FP compared to milk from 1,200 m altitude, except SNF, FP and AA, which were not statistically significant. The analysed milk during the four months of lactation period has significantly increased (P < 0.05) in TS (from 15.65 to 25.46%); MF (6.49 to 10.80%); SNF (9.16 to 14.66%); P (4.46 to 6.94%); L (3.96 to 6.52%); ash (0.74 to 1.20%); TA (9.90 to 14.53 °SH); whereas changes in FP value (-0.611 to -0.709 °C), AA (6.68 to 6.76) and D (1.035 to 1.053 g cm-3 ), have been statistically non-significant. The interactions between altitude*lactation period on milk composition (TS, MF, SNF, P, L, ash) of crossbred ‘Sharri’ sheep and physical properties (FP, TA, AA and D) were nonsignificant.

    Influence of the farm location and seasonal fluctuations on the composition and properties of the milk
    (Estonian University of Life Sciences, 2024) Ramadani, Xh.; Kryeziu, A.; Kamberi, M.; Zogaj, M.
    The aim of this research was to investigate the variations in the chemical composition as well as the physical and microbiological properties of raw milk depending on the farm location and the season. Seven dairy farms located in seven different geographic regions of Kosovo were included in the experiment. Milk composition (total solids – TS, milk fat – MF, solids nonfat – SNF, protein – P, lactose – L, active acidity – AA (pH), density – D, colony formatting unit – CFU, and somatic cells count – SCC) were analysed during a one-year period from December 2021 to November 2022. In a total of 252 analysed milk samples, the research showed an average good composition in accordance with the Kosovo regulation for milk quality: TS (13.71%), MF (5.12%), SNF (8.60%), P (3.25%), L (3.87%), AA (6.83), D (1.028 g cm-3), but higher number of CFU (194,048 mL-1), and SCC (418,429 mL-1). Farm location showed significant differences (P < 0.01) in TS, MF, SNF, P, D, CFU and SCC, whereas L content and AA value were statistically non-significant. The lower value of TS, MF, and CFU were detected in summer, AA, and P in spring, SNF and L in autumn, D value was similar in all seasons, whereas only SCC was present in winter season. The differences in all analysed parameters with respect to the season were statistically non-significant.
