Inclemency of weather frequently causes critical water contents in cereal grains above 15%. Ensiling in pre‐mature condition may be an alternative to other techniques of preservation. Aim of this study was to compare apparent total tract digestibility (D_t; barley, wheat, triticale, rye) of proximate nutrients and pre‐caecal digestibility (D_pc; barley, wheat) of amino acids (AA), respectively, from cereal grains in ensiled and almost dry condition. Moistly harvested cereal grains (67–73% dry matter) were milled through a 4‐mm sieve and ensiled with lactic acid bacteria (LAB, 3 × 10⁵ colony forming units/g Lactobacillus plantarum DSMZ 8862 and 8866). To investigate D_t, two trials were conducted with six Mini‐Lewe pigs and four German Landrace pigs, respectively. D_pc of AA was determined using four German Landrace pigs with ileo‐rectal anastomosis. D_t of proximate nutrients did not differ between cereal grains and …
