It was confirmed in metabolic experiments with 4 individuals of roe deer (2 males and 2 females with the live weight of 20.8 and 17.9 kg, respectively) that due to the animals’ selective choice of a part of feeds there was no significant difference in the intake of lucerne hay of different quality and high-quality meadow hay (515.86 ± 66.97 and 597.82 ± 94.87 g, respectively). However, different quality of lucerne hay influenced the animals’ intake of crude protein and crude fibre. When the animals were fed meadow hay, they took in significantly less crude protein and fibre and significantly more nitrogen-free extract, fat and ash. Digestibility of crude protein was observed to be significantly decreased in hay of lower quality (by 10.1%). Digestibility coefficients for crude protein, crude fibre, organic matter and fat were significantly lower in grass hay compared to lucerne hay. Based on the coefficients of nutrient digestibility it can be stated that meadow hay, even if of excellent quality, is not a suitable supplement for the roe deer.
