“…The pigs were housed in metabolic cages and had free access to tap water. For determining D pc of AA, regression method (GfE, 2005a; Mosenthin et al., 2007) after stepwise supplementation (4 levels) of casein and threonine to the grain‐only diet (Table 1) based on metabolic body weight of the animals was used. Casein was supplemented to accomplish basal levels of crude protein, lysine, methionine, threonine and leucin.…”

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 × 10(5) 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 their silages, except for ether extract, which was more digestible in ensiled than dry wheat, triticale and rye (p < 0.05). Lysine content was lower in ensiled than dry barley and wheat. In barley, ensiling was accompanied by reduced D(pc) of lysine and histidine (p < 0.05). In wheat, ensiling increased D(pc) of lysine, methionine, threonine and leucin (p < 0.05). Ensiling of pre-mature cereal grains with LAB can serve as a reasonable storage alternative. However, as limited data are yet available, further research is required to understand completely the impact of ensiling on nutritional value as indicated, for example, by the lysine content and the D(pc) of certain AA.

“…The CIAD of CP and AA in the diets containing bakery meal and broken rice also represented the CIAD of CP and AA in these ingredients. Data from the bakery meal diet were used to calculate the contribution of AA from bakery meal to the diets containing FFRB or DFRB and the CIAD of CP and AA in both sources of FFRB and in DFRB, were calculated using the difference procedure (Mosenthin et al, 2007). Outliers and homogeneity of the variances among treatments were tested using the UNIVARIATE procedure of SAS (Version 9.4: SAS Institute, Inc. Cary, NC).…”

“…Furthermore, it was agreed upon to transform apparent ileal digestibility (AID) values into their corresponding standardized values by correcting for basal endogenous AA losses to further improve the accuracy in predicting the amount of AA available to the pig (e.g. Mosenthin et al, 2007).…”
