Abstract
In the field trials carried out in 1997–1999 at two stations (Lipnik and Strzelce) three oat varieties (naked oats Akt and STH 296 and conventional hulled oat Bajka) grown at two nitrogen doses were compared. The N doses (kg/ha) were: 50 and 100 (Lipnik) 70 and 100 (Strzelce, 1998), 60 and 100 Strzelce, 1999). The yields of: protein, oil, essential amino acids (lysine, methionine, cysteine, threonine) and metabolizable energy were calculated based on of the grain yield, chemical composition of grain and its digestibility for pigs. The naked oat varieties Akt and STH 296, as compared with the hulled var. Bajka, contained more protein (by 26 and 34 g/kg, respectively), oil (40 and 42 g/kg) and amino acids, especially threonine, but less crude fibre (73 and 70 g/kg, respectively). The metabolizable energy of the naked oat varieties exceeded those of hulled oats up to 3.2 MJ/kg (30%). The oil yield of the naked oats was higher by about 106 kg/ha (40%) than that of the hulled oat. The yields of protein, amino acids (lysine, methionine, cysteine, threonine) and metabolizable energy, were lower by 7, 8 and 9%, respectively. It was due to the lower grain yield of the naked varieties, even after excluding the content of husk in the hulled variety. The higher nitrogen doses increased the content of protein by approx. 10 g/kg and that of amino acids by 1.6 g/kg, at the same contribution of the amino acids to the total protein. In contrast, the content of the oil crude fibre and metabolizable energy for pigs remained unchanged. The yields of nutritive components: protein, oil, amino acids and metabolizable energy increased under the higher nitrogen treatment by 19, 8, 19 and 9%, respectively.
