Sažetak
Grasses are the most natural and cheapest feed for dairy cows, and ensiling is the most widespread way of conserving grasses. High milk production is obtained only from silages made from young grasses that are much harder to ensile than older grasses. The quality of silage is determined by chemical composition of green material prior ensiling and the quality of ensiling process. This paper examines the values of fermentation parameters of silages primarily as an ensiling process quality indicators and secondly their impact on dairy, health and fertility of dairy cows. The following parameters, their optimal values and their impact on silage quality and milk production are discussed: dry matter, acidity of silage, lactic acid and volatile fatty acids (acetic and butyric acid), ethanol, protein fractions (ammonia, soluble protein, biogenic amines) and organoleptic analysis of grass silage. Furthermore, the recommendations for the production of high quality grass silage are presented.
