Opis:
The research aimed to quantify the occurrence of se- lected mycotoxins: AFB1 (aflatoxin B1), DON (deoxynivalenol) and ZEN (zearalenone) in maize and grass silages. The silage was prepared in foil bales without the addition of differentiating factors. Silages derived from 36 farms located in Wielkopolskie voivodeship. The total number of mould fungi and the pH value were determined in the collected samples. The level of contami- nation with selected mycotoxins was determined by high-perfor- mance liquid chromatography (HPLC). Based on the obtained results, it was found that the total number of mould fungi in the examined silage samples was in the range 5.00–6.90 log CFU g-1 fresh weight, pH value in the range 3.34–4.73. It was shown that maize silage is more contaminated with mycotoxins than grass silage. In the tested samples, statistically significant differences (P <0.05) were found only for the mycotoxin ZEN. ZEN content was 74% higher in maize silage compared to grass silage. Con- tamination of silages with mycotoxins AFB1 and DON was at a similar level, and it was 4.22 and 354.14 μg kg-1 for maize and 4.98 and 330.25 μg kg-1 for grasses, respectively.

Opis:
The aim of the study was to determine the influence of a commercial bacterial inoculant PK (Lactobacillus plantarumK KKP/593/p, L. plantarum C KKP/788/p, L. brevis KKP 839, L. buchneri KKP 907) and a ML preparation (L. buchneri ATCC 4005, L. diolivorans LGM 19667, L. reuteri ATCC 23272) on the concentration of 1,2-propanediol and short-chain fatty acids (acetic acid, propionic acid ) on maize silage aerobic stability pro-longation. The silage was prepared in laboratory microsilos with a capacity of 10 dm3. The basic composition of the feed was de-termined according to the AOAC. The measure of oxygen stabi-lity was the time needed to raise the silage temperature by ≥2 ̊C about the ambient temperature.The research showed that during 120-day ensilage, the ap-plied preparations significantly (p<0.05) reduced the content of dry matter, water-soluble sugars and pH. The concentration of lactic acid, acetic acid and propionic acid in the inoculated sam-ples increased significantly. 1,2-propanediol and 1-propanol were not found in control silages. The addition of PK and ML signifi-cantly increased the concentration of these substances. The num-ber of lactic acid bacteria in silage with biological additives was significantly higher, and the number of yeasts and mould fungi was lower compared to the control. The applied mixtures of PK and ML significantly extended the time of aerobic stability of si-lages.
