Abstract

V raziskovalnem delu smo od konca marca do sredine aprila leta 2023 čebelje družine v čebelnjaku v Lovrencu na Pohorju hranili s prehranskimi dodatki. Po vzorčenju čebel so bile analize opravljene na Fakulteti za kmetijstvo in biosistemske vede v Pivoli, Hoče. Za naš poskus smo uporabili 10 panjev. Panje smo razdelili v 5 skupin. Vsaka skupina je vsebovala 2 družini, ki sta bili vizualno zdravi, brez simptomov bolezni in škodljivcev. Označili smo jih z navedbo datum hranjenja in vrsto dodatka v hrani. 4 skupine panjev smo hranili z vnaprej pripravljenimi raztopinami izvlečka gob. Hranili smo jih ob ponedeljkih, sredah in petkih, približno ob istem času. Kontrolo družin in vzorčenje čebel smo izvajali vsak ponedeljek. Hranjenje čebel je potekalo s pomočjo sirupa, ki je bil sestavljen iz 50 % vode in 50 % sladkorja ter dodatka (izvlečka gob). Kontrolni družini smo hranili z raztopino sladkorja v vodi (1:1; w:w). Za krmljenje z izvlečki gob smo uporabili sirup, ki je vseboval 4 % izvlečka iz gob. Uporabili smo izvlečke iz gob Ganoderma lucidum, Hericium erinaceus, Inonotus obliquus in Trametes versicolor. Družine so bile hranjene tri tedne, trikrat na teden. Skupno je v poskusu vsaka družina prejela 3 litre hrane. Končna analiza kaže, da imajo izvlečki gob značilen vpliv na antioksidativne lastnosti pri čebelah. Največje učinke smo ugotovili po krmljenju izvlečka gobe Inonotus obliquus. Izvlečki gob so povzročili povečanje koncentracije encimov (ALP, ALT in AST) od 14. dne krmljenja dalje, v primerjavi s kontrolno skupino družin, ki so bile hranjene samo s sladkornim sirupom. Najvišje vrednosti encimov in zato najboljše indikatorje vitalnosti čebel je dal izvleček gob Inonotus obliquus saj je vplival na dolgoživost čebel in izboljšal zdravstveno stanje čebel

Secondary title:	Impact of food supplements on the vitality of honey bee colonies
Secondary abstract:	From the end of March to mid-April 2023, bee colonies were fed with nutritional supplements in an apiary in Lovrenc na Pohorju. After taking samples from the bees analyses were carried out at the Faculty of Agriculture Agriculture and Life Sciences in Hoce. 10 hives were used for the experiment. We divided the hives into 5 groups. Each group contained 2 families that were visually healthy, with no symptoms of disease or pests. We marked them with the date of feeding, and the type of food additive. Four groups of hives were fed with pre-prepared solutions of mushroom extract. We fed them on Mondays, Wednesdays and Fridays, around the same time. We checked the colonies and sampled the bees every Monday. The bees were fed syrup, which consisted of 50% water, 50% sugar and a mushroom extract additive. We feed the control family with a solution of sugar and water (1:1; w:w). The mushroom extracts was administered via a syrup that contained 4% mushroom extract. We used extracts from the mushrooms Ganoderma lucidum, Hericium erinaceus, Inonotus obliquus and Trametes versicolor. Families were feed three times a week, for three weeks. In total, each family received 3 liters of food. The final analysis shows that mushroom extracts have a characteristic effect on antioxidant properties. The greatest effects were found after feeding the mushroom I. obliquus. The mushroom extracts resulted in an increase in enzyme concentrations (ALP, ALT and AST) from day 14 of feeding compared to a control group of families fed sugar syrup alone. The highest enzyme values and therefore the best indicators of bee vitality, resulted from feeding the mushroom extract I. Obliquus. This seemingly produced benefits for the longevity and health status of the bees
