Studies were carried out with 12 pigs (Yorkshire × Landrace) to determine the effect of dietary fibre level on amino acid digestibility. The pigs were weaned at 21 d of age and fitted with a simple T-cannula at the distal ileum at 23 or 24 d of age. The pigs were fed four isonitrogenous corn starch-based soybean meal diets (22.5 % crude protein) containing 4.3, 7.3, 10.3 and 13.3% Solkafloc according to a balanced two-period change-over design. The pigs were fed four times daily, equal amounts, at 6-h intervals. The diets were supplied at a rate of 5% of the average body weight which was determined at the initiation of the first (8.8 kg) and second (11.7 kg) experimental period. Each experimental period comprised 10 d. Feces were collected for 48 h on days 6 and 7 and ileal digesta for 24 h during days 8, 9 and 10. Chromic oxide was used as digestibility marker. The dietary inclusion of Solkafloc, up to 13.3 %, did not affect (P > 0.05) the apparent ileal as well as the fecal digestibilities of crude protein and amino acids. In conclusion, starter pigs can tolerate up to 13.3% Solkafloc, equivalent to 16.8% neutral-detergent fibre, in corn starch-based soybean meal diets without a depression in amino acid digestibility.

SUMMARYThough bitter white lupin (Lupinus albus L.) is a traditional crop in Ethiopia, sweet lupins are new to the country. As a result, the nutritional value of low-alkaloid lupins has not been evaluated under Ethiopian conditions. Crude protein, amino acid and alkaloid contents of 16 cultivars of three annual lupin species grown in four lupin growing locations (Merawi, Finoteselam, Kossober-1 and Kossober-2) of Ethiopia were evaluated. Location × cultivar interaction was a significant source of variation for all traits (p < 0.0001). In all locations, blue entries had either similar (p ≥ 0.0584) or higher (p ≤ 0.0235) forage crude protein content than the Local Landrace, white group and yellow entry. Compared with the Local Landrace, white and blue entries, the sole yellow entry had higher (p ≤ 0.0148) seed crude protein content at all locations except at Kossober-2, where it had similar (p = 0.8460) crude protein content as white entries. The Local Landrace had the highest forage and seed alkaloid contents. However, sweet blue Vitabor and Sanabor entries had the lowest forage and seed alkaloid contents, respectively. Low alkaloid and higher crude protein contents of sweet lupins grown in Ethiopia show the possibility to use sweet lupin forage and seeds as cheap home-grown protein source for livestock feed and human food in the country. However, for more reliable information, the laboratory results need to be verified by animal and human evaluations of the crop.
