The aim of the experiment was to analyzed coefficients of digestibility of the maize silage nutrients in horse feeding. Horses of Slovak warmblood breed engaged in the research were 2.5 ± 0.5 years old. Horses in boxes without bedding to avoid eating it and excrement contamination were stabled. Horses individually with ad libitum access to water were housed. The boxes with trough for corn silage were equiped. The corn silage contained 362.3 g of dry matter, 74.1 g of crude protein, 27.1 g of crude fat and 948.2 g of organic matter in kg of dry matter. The feed twice a day, in the morning and in the evening was given. The feed intake and leftovers were weighed every day. Excrements immediately after excreting to avoid urine contamination into plastic containers were collected and weighed. The content of nutrients in the feed intake and in the excrements were analysed. In analysed samples the gravimetric dry matter amount by drying at 103 ± 2 °C, crude protein content by Kjeldahl method, fat content by extraction method according to Soxhlett – Henkel, ash content by burning the sample at 530 ± 20 °C in muffle furnace and organic matter content by calculation were determined. Coefficients of apparent digestibility in percent from taken in and excreted nutrients were calculated. In maize silage for horse feeding an average coefficient of digestibility of dry matter 61.94%, of crude protein 56.03%, of crude fat 72.34% and of organic matter 65.19% was found.
