The nutritive value of canola meal for early-weaned pigs

Abstract Four experiments using 900 crossbed pigs were conducted to determine the nutritive value of canola meal (CM) for pigs weaned at 3 or 5 weeks of age. Diets were based on barley and wheat, and CM replaced 0, 25, 50, 75 or 100% of the protein supplied by soya bean meal (SBM) on an isoenergetic and isonitrogenous basis. In Experiments 1 and 2, with pigs weaned at three weeks of age, regression analyses of the results indicated that, for each percent addition of CM to the diets, there was a significant ( P P P > 0.05) by the level of CM in the diet.

Canola meal as a protein supplement for growing-finishing pigs

Abstract Four hundred crossbred pigs of an average initial weight of 20.3 kg were used in two experiments to determine the effect of canola meal (CM) as a protein supplement for growing (20–60 kg) and finishing (60–90 kg) pigs. Diets were based on barley and wheat and CM replaced 0, 25, 50, 75 and 100% of the protein supplied by soya-bean meal (SBM) on an isoenergetic and isonitrogenous basis. Average daily feed intake and feed-to-gain ratio of the growing pigs were not significantly (P > 0.05 affected by the level of CM in the diet. Rate of gain was significantly (P 0.05) by replacement of SBM by CM. It was concluded that growing pigs can be successfully fed diets containing a maximum of 9% CM, however, CM can be used as the sole protein supplement in the diets of finishing pigs.

Effects of partial removal of alkaloids in sweet white lupin seed on performance and nitrogen balance in lambs

The impact on animal performance of extracting alkaloids in lupin seed (LS) was evaluated with 30 lambs (average weight, 14 kg) fed for 90 d. Sunflower seed (SFS) in the control diet was replaced by intact LS, or LS steeped in water (detoxified) to remove alkaloids. The test diets contained either 15% (LUI-15) or 30% (LUI-30) intact LS, or 15% (LUD-15) or 30% (LUD-30) detoxified LS. Lambs fed SFS exhibited lower (P 0.05) across diets. This study suggests that alkaloids in LS restricted feed intake and limite...
