THE MYCOLOGICAL STATUS OF GREEN FORAGES AND SILAGES FROM A MIXTURE OF LEGUMES WITH GRASSES AND WHOLE CROP MAIZE
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2017, Vol 44, Issue 338
Abstract
The number of fungi (yeasts and moulds) in silages is the determinant of their hygienic quality. The research material was green forage from a mixture of legumes and grasses and whole crop maize. The study was conducted in 2012‒2014. Each year, green forages of a 2nd swath of a legume-grasses mixture being in 3-year field crop were ensiled. The green forages from maize of the same hybrid, cultivated according to the principles of crop rotation, were ensiled in wax stage. Chopped green forages was compacted and ensiled in minisilos with a capacity of 8654 cm3, which were opened after 6 weeks. In order to determine the number of moulds and yeasts in green forages and silages, mycological analysis was performed in accordance with PN-ISO 21527-1 : 2009. The mycological status of ensilaged green forages was bad. The number of moulds of the green forages of the legume-grasses mixtures was from 5.4225 (3rd year) to 5.4472 lg cfu · g‒1 (1st year), and yeast was at level from 4.9977 (3rd year) to 5.5792 lg cfu · g‒1 (1st year). Moulds in whole crop maize occurred in the number of 4.6514 (1st year) to 6.4928 lg cfu · g‒1 (2nd year), while yeast from 6.6710 (2nd year) to 7.2657 lg cfu · g‒1 (1st year). Silages had significantly (P ≤ 0.001) less fungus than in green fodders. The hygienic quality of silages from the legume-grass mixtures was good in each year of the study. The number of mould and yeast did not exceed 3 lg cfu · g‒1. Silages from whole crop maize had bad hygienic quality. Only in the silage of the 3rd year of the study, the presence of mould at a level of 1.7940 was noted, but yeast amounted to 6.2810 lg cfu · g‒1.
