Loomade tervis kui ka toodanguvõime sõltuvad etteantavast sööda kvaliteedist. Mäletsejalised toituvad peamiselt rohusilost, mispärast on oluline sööta neile võimalikult kvaliteetset silo. Antud bakalaureusetöö eesmärk on uurida silo kvaliteedi erinevusi 2020. ja 2023. aastal valmistatud silodest. Andmed saadi Eesti Maaülikooli söötmisteaduse õppetooli sööda ja ainevahetuse uurimise laboratooriumist ning andmete analüüsiks kasutati programmi Excel. Antud uuringust saab järeldada, et silo tootjad on aja jooksul muutunud rohkem teadlikumaks närvutamise olulisusest. Samuti oli märgata, et 2023. aastal oli liblikõieliste osakaal seemnesegudes suurem ning rohusaagi koristamisega alustati taimestiku nooremas arengufaasis. Antud uuring annab ülevaate, kuidas silo kvaliteet on ajas muutunud kuivainesisalduse, botaanilise koostise, niite, hoiustamisviisi ja silokindlustuslisandi kasutamise alusel.
The health and production capacity of animals depend on the quality of the feed provided. Ruminants feed mainly on grass silage, which is why it is important to feed them the highest quality silage possible. The aim of this bachelor's thesis is to analyze the differences in silage quality between silages produced in 2020 and 2023. The data was obtained from the Feed and Metabolism Research Laboratory of the Estonian University of Life Sciences and the Excel program was used for data analysis. It can be concluded from this study that silage producers have become more aware of the importance of wilting over time. It was also noticeable that in 2023 the proportion of leguminous plants was higher in seed mixtures and that grass harvesting began in the younger developent phase of the vegetation. This thesis provides an overview of how silage quality has changed over time based on dry matter content, botanical composition, mowing, storage method and use of silage additive.
