The aim of this study was to evaluate the quality of harvested green mass and prepared silage from Asteraceae species: Helianthus annuus, Silybum marianum, Cynara cardunculus and Silphium perfoliatum grown in an experimental field of the National Botanical Garden (Institute), Chişinău, Republic of Moldova. It was determined that the nutrient content of the harvested mass varied among the species: 90-159 g/kg CP, 300-358 g/kg CF, 67-88 g/kg ash, 326-379 g/kg ADF, 555-646 g/kg NDF, 49-60 g/kg ADL, 34-145 g/kg TSS, 272-328 g/kg Cel, 209-267 g/kg HC with nutritive and energy values 58.4-63.5 % DDM, RFV=86-104, 11.76-12.50 MJ/kg DE, 9.65-10.26 MJ/kg ME and 5.67-6.28 MJ/kg NEl. The silages prepared from the studied Asteraceae species are characterized by specific smell and colour, pH = 3.94-5.39, 4.8-8.4 g/kg acetic acid, 16.4-34.6 g/kg lactic acid, 0-0.8 g/kg butyric acid, 95-166 g/kg CP, 81-135 g/kg ash, 315-380g/kg CF, 355-421 g/kg ADF, 605-653 g/kg NDF, 53-65 g/kg ADL, 302-356 g/kg Cel, 200-276 g/kg HC, 0-36 g/kg TSS, 56.6-61.2 % DMD, 11.18-12.10 MJ/kg DE, 9.18-9.93 MJ/kg ME, 5.19-5.95 MJ/kg NEl. The ensiled mass substrates for anaerobic digestion had optimal C/N=15-30 and biochemical methane potential varied from 300 to 333 l/kg ODM. The studied Asteraceae species have optimal nutrient content, and they can be used as an alternative feed source for livestock, also and as feedstock for biogas production. Among these species, Cynara cardunculus has a particularly high economic value. |
