Beef catile are given grass silage ad lib., up to 20 kg daily. In 1992, 38 samples of grass silage were analysed. The mean content of dry mater (DM) was 333.5 g. kg⁻¹ and of crude ash 97.41 g. kg⁻¹DM. Mean contents of some essential macro elements per kg DM were: calcium 6,99 g; phosphorus 3,04 g; magnesium 2.23g; potassium 18,22g and sodium 0.70 g. Taking into account the mean content of DM in silage the animals consumed the above stated quantity of elements by 3 kg of grass silage.
