“…The content of coumarin in silage corresponds to the percentage of WSC in silage produced from a mixed culture (Kadaňková et al, 2019) and can be reduced by reducing the amount of WSC shreddings used in the silage. Popp et al (2015) inform that MCS have to become used to the presence of coumarin in biogas plants during the AD, and thus the technology of mixed culture cannot be used by fits and starts but over a long time only (Kintl et al, 2020;Huňady et al, 2021). It is not only the content of nutrients that is used in evaluating the total production of biomass but also the health condition of plants.…”

Licensed under a Creative Commons Attribution 4.0 International LicenseThe effect of growing maize with undersown crops on the content of mycotoxins in maize biomass was studied. Small plot experiments were conducted in 2019 on two sites with different soil and climatic conditions: Žabčice and Troubsko. Three treatments of intermediate crops (Italian ryegrass; Fodder vetch and a mixture of both) were undersown into the space between the rows of maize. The maize was harvested at a dry matter content of 35% at the Troubsko experimental site and 43% at the Žabčice experimental site. After the harvest of maize, samples of green biomass (shreddings) were dried at 60 °C and then analyzed for the content of mycotoxins such as deoxynivalenol (DON), aflatoxin (AF, L), and fumonisin (FUM). An average yield of maize shreddings ranged from 16.50 to 21.57 t/ha of dry matter within the individual treatment. The contents of mycotoxins from the sites differed in their statistical significance, and both experimental sites showed the lowest concentrations of AFL in maize shreddings while average concentrations of FUM and DON were always the highest. In most observations, treatments with the undersown crops reached the same values as the control treatment. Only in one treatment (mixture of Italian rye grass and Fodder vetch), an increase in the AFL content (by 0.3 µg/kg) was detected. Based on the performed analyses, it is possible to state that no adverse influence of undersown crops on the occurrence of mycotoxins in maize shreddings was recorded using the chosen methodology of cultivation. Exceeded limit values for the content of mycotoxins in feeds according to 2006/576/were not recorded.

The efficient use of the biological potential of the leguminous plants that are adapted to the local climatic conditions becomes more and more relevant. The local ecotype of the species Lathyrus sativus, Lathyrus sylvestris, Lathyrus tuberosus, Vicia hirsuta, Vicia sativa, Vicia tenuifolia maintained in monoculture on experimental land in the NBGI Chişinău, served as objects of study. We found that the dry matter of the studied whole plants contained 169-257 g/kg CP, 96-125 g/kg ash, 219-346 g/kg CF, 244-371 g/kg ADF, 427-576 g/kg NDF, 34-58 g/kg ADL, 210-313 g/kg Cel, 183-205 g/kg HC, 64-150 g/kg TSS, with 59.3-69.4% DMD, RFV = 93-151, 11.87-13.55 MJ/kg DE, 9.75-11.13 MJ/kg ME, 5.77-7.22 MJ/kg NEl. The prepared hay contained 153-264 g/kg CP, 91-135 g/kg ash, 244-356 g/kg CF, 294-393 g/kg ADF, 475-606 g/kg NDF, 36-65 g/kg ADL, 258-329 g/kg Cel, 191-214 g/kg HC, 6-99 g/kg TSS, with 59.2-66.0% DMD, RFV = 90-129, 11.57-12.95 MJ/kg DE, 9.50-11.09 MJ/kg ME, 5.51-7.10 MJ/kg NEl. The haylage is characterized by pleasant smell and color, pH = 4.40-4.95, 4.7-6.1 g/kg acetic acid, 27.9-38.0 g/kg lactic acid, butyric acid was not detected, 159-180 g/kg CP, 105-125 g/kg ash, 296-343 g/kg CF, 316-360 g/kg ADF, 460-579 g/kg NDF, 51-55 g/kg ADL, 263-309 g/kg Cel, 142-219 g/kg HC, 43-106 g/kg TSS, 60.9-64.1% DMD, RFV = 98-129, 12.03-12.61 MJ/kg DE, 9.88-10.35 MJ/kg ME, 5.89-6.37 MJ/kg NEl. The harvested fresh mass and the haylage prepared from the studied species can be used as substrates in biogas production via anaerobic digestion for renewable energy production, with carbon nitrogen (C/N) ratios 12-20. The biochemical methane potential reached 320-378 litre/kg organic matter. The investigated leguminous species are an important forage source for livestock, many birds, bees and entomophagous insects, and they are excellent plants for erosion control and for reseeding and increasing the economic value of permanent and temporary grasslands. The harvested biomass can be used as alternative fodder for farm animals or as substrates in biogas generators for the production of renewable energy.
