Effects of tehnological proceedings in ground hay curing on losses and fodder quality

V okviru CRP »Tehnološke rešitve za pridelavo kakovostnega sena« na Kmetijskem inštitutu Slovenije smo v letu 2017 opravili dva poskusa v severovzhodnem delu Slovenije. Poskusa sta temeljila na analiziranju vplivov tehnoloških postopkov sušenja krme na izgube in kakovost le-te. V obeh poskusih smo odvzeli vzorce za analizo izgub in kakovosti krme. V prvem poskusu, ki je bil zastavljen na dveh površinah, (na prvi so prevladovale trave, na drugi metuljnice), smo ugotavljali vpliv botanične sestave na izgube in kakovost krme. Na drugem poskusu, ki je bil zasnovan na trajnem travinju pa smo analizirali vpliv delovne hitrosti in števila vrtljajev delovnih strojev na izgube in kakovost krme. Rezultati prvega poskusa so pokazali statistično značilne razlike v izgubah in kakovosti krme glede na prevladujoče rastline v ruši. Različne delovne hitrosti in števila vrtljajev delovnih strojev pa značilno vpliva na parameter kakovosti krme, ne pa tudi na njene izgube. Pri manjših vrtljajih in manjši delovni hitrosti delovnih strojev so vrednosti NEL v krmi višje kot pri krmi, kjer so bili uporabljeni večji vrtljaji in večje delovne hitrosti.In the year 2017 the team within project » Technological Solutions for Cultivation of Quality Hay« on the Agricultural Institute of Slovenia finished two experiments in the Northeast of Slovenia. Experiments were based on analysing effects of technological proceedings in hay curing on losses and fodder quality. We took examples of the fodder and evaluated losses and quality of fodder at both experiments. At the first experiment, that was divided on two surfaces (grasses were developed on first surface, per other developed leguminosae), we were checking influence of botanical composition. At the second experiment on permanent grass we analysed influence of working speed and number of rotations of working machines on losses and quality. Results from the first experiment showed statistically characteristic differences considering dominant plants in losses and quality of fodder. At other experiment different working speeds and numbers of rotations influence parameter of quality characteristically, but not losses of fodder. The net energy value was at smaller rotations and smaller working speed more highly than at larger rotations and working speed
