The Welsh Plant Breeding Station at Aberystwyth has bred varieties of oats which do not retain their husk (Lemma and Palea) when threshed. These “naked” oats (Avenu nuda) are of a relatively high nutritional value, and at Trawsgoed EHF a spring sown variety, Rhiannon, has been used to evaluate their suitability as an alternative to expensive cereal products, such as oat flakes, presently used in piglet rations. Chemical analyses showed Rhiannon to contain in each kg 15.5 MJ of digestibile energy, 132 g of crude protein, 5.5 g of lysine and 8.2 g of lipid. Crude fibre content was low as expected (21 g/kg).
