Abstract
Dodatak ugljikohidrata biljnoj masi prilikom siliranja pospješuje rast i razvoj mikroorganizama tijekom fermentacije u silosu. Sirutka u prahu je bogata laktozom, pa njezin dodatak biljnoj masi prije siliranja dovodi do bržeg zakiseljavanja biljne mase u silosu i postizanju niže završne pH vrijednosti. U radu je analizirano 5 razina dodatka sirutke biljnoj masi poluprirodnog travnjaka prije siliranja u laboratorijske silose (0, 6, 12, 24, 48 g) na 200 g svježe biljne mase u 5 ponavljanja. Nakon 47 dana od zatvaranja laboratorijskog silosa, utvrđena je pH vrijednost fermentirane krme i sadržaj suhe tvari (ST). Osušeni i samljeveni uzorci su analizirani NIRS aparatom radi procjene kemijskih parametara hranidbene vrijednosti fermentirane krme: sirovi proteini (SP), sirove masti (SM), pepeo i nedušićne ekstraktivne tvari (NET). Dodatak sirutke u prahu je povećao (p<0,05) sadržaj ST i NET i smanjio (p<0,05) sadržaj SP i SM i pH vrijednost fermentirane krme. Na temelju rezultata istraživanja može se zaključiti da dodatak sirutke u prahu biljnoj masi poluprirodnog travnjaka udjela od 3 % (TR 2) prilikom siliranja ima pozitivan utjecaj na pH vrijednost i hranidbenu vrijednost fermentirane krme.
Abstract (english)
The addition of carbohydrates to forage at ensiling promotes the growth and the development of microorganisms during fermentation in the silo. Dried whey is rich in lactose, and its addition to forage at ensiling leads to faster acidification thus the silage achieves a lower final pH value. In this paper, 5 levels of dried whey were supplemented (0, 6, 12, 24, 48 g) to 200 g of semi-natural grassland forage at ensiling into laboratory silo in 5 replicates. Forty-seven days after the laboratory siloees were closed, the pH of fermented forage and dry matter content (DM) were determined. The dried and grinded samples were analized by NIR spectroscopy to predict crude protein (CP), crude fat (CF), ash and N-free extract (NFE) of fermented forage. The dried whey supplementation to semi-natural forage at ensiling increased (P <0.05) DM concentration and NFE and reduced (P <0.05) the concentration of CP, CF and the pH value of fermented forage. Based on the results of the research it can be concluded that the addition of dried whey to semi-natural grassland at ensiling part of 3 % (TR 2) has a positive impact on the pH value and nutritional value of the fermented forage.
