The aim of this study was the monitoring of the chemical composition of olive oil at different ripening stages to determine the appropriate harvesting time during any given crop season in the ...northern Adriatic region. For this purpose, from September to November, two Croatian olive cultivars (Drobnica and Buza) were taken from two different olive orchards and for the respective olive oils, prepared on a laboratory scale, the major saponifiable, unsaponifiable and phenolic compounds were determined. Based on the chemical analyses performed, the optimal harvesting time has been set in October for both cultivars. Buza had a higher oleic acid, but lower total sterols, squalene and total alkanols. Compared to the local cultivars, the studied cultivars had a high total phenolic content and antioxidant activity. The antioxidant activity and concentrations of total phenols correlated with α-tocopherol in oil samples taken during the ripening progress. Finally, trace minerals detected in Buza and Drobnica oil differed, which can be an indicator of oxidative stability and authenticity of oils.
Grazing animals explore different forage resources to satisfy their daily nutrient needs, following specific spatial and temporal patterns throughout the year. In this study four different flocks of ...sheep and goats (two of each species) were selected to record their spatial location with a handheld GPS during spring, summer and winter. At the same time, three animals in each flock were followed to study their grazing activities by direct observation. These data with the time information and a detailed land use map were manipulated in a GIS to assign animal activities to different forage resources. Sheep and goats were travelling long distances (7.5 km and 9.0 km, respectively) to satisfy their nutritional needs throughout the year. They were found to graze in two main forage resources, rangelands (grasslands, shrublands and forest ranges) and agricultural land (fallow land, stubble fields and temporary pastures). Both grazer species spent significantly less time (P≤ 0.05) feeding in rangelands (38.9% & 18.1%) than in agricultural land (63.6% & 53.4%) during spring and summer. It appears that a heterogeneous landscape is necessary for supporting extensive farming systems of small ruminants since rangelands and agricultural land complement each other in providing forage throughout the year.
Pašne živali se hranijo z različnimi krmnimi rastlinami, da zadostijo svojim dnevnim potrebam po hrani, pri tem sledijo različnim prostorskim in časovnim vzorcem skozi leto. V raziskavi smo izbrali štiri različne črede ovac in koz (dve za vsako vrsto) in opazovali njihovo prostorsko razporeditev z ročnim GPS spomladi, poleti in jeseni. Istočasno smo tri živali v vsaki čredi neposredno opazovali pri paši. Podatke o času in natančno karto rabe tal smo obdelali v GIS-u, da smo dobili povezavo med aktivnostmi živali in različnimi krmnimi rastlinami. Ovce in koze so prehodile dolge razdalje (od 7,5 km do 9,0 km), da so v celotnem letu zadovoljile potrebe po hrani. Pasle so se na dveh glavnih tipih krme: pašnikih (travišča, grmišča in gozdni robovi) in kmetijskih površinah (prahe, strnišča in začasni pašniki). Obe vrsti sta se statistično značilno (P≤ 0.05) pasli krajši čas na pašnikih (38,9% in 18,1%) kot na kmetijskih površinah (63,6% in 53,4%) v spomladanskem in poletnem času. Očitno je, da je pestrost krajine nujna za ekstenzivne kmetijske sisteme z drobnico, saj se pašniki in kmetijske površine dopolnjujejo pri celoletni oskrbi s krmo.
