Abstract Energy values and amino acid (AA) digestibility of dried yeast (DY) and soybean meal (SBM) were determined in 2 experiments with growing pigs. Experiment 1 was conducted to determine the digestible energy (DE) and metabolizable energy (ME) in DY and SBM. Thirty barrows with a mean initial body weight (BW) of 20.6 kg (SD = 1.04) were assigned to 5 dietary treatments in a randomized complete block design with period and BW as blocking factors. A reference diet was prepared with corn, canola meal, and soybean oil as energy-contributing ingredients. Four additional diets were prepared by adding 5 and 10% DY or SBM at the expense of energy-contributing ingredients in the reference diet. The ratio of corn, canola meal, and soybean oil was kept consistent across the experimental diets. Each experimental period consisted of 5-d adaptation and 5-d quantitative collection of feces and urine. Test ingredient-associated DE or ME intake (kcal/d) was regressed against test ingredient intake [kg dry matter (DM)/d] to estimate the DE or ME in test ingredients as the slope of linear regression model. The DE in DY was estimated at 3,933 kcal/kg DM, which was not different from the estimated DE in SBM at 4,020 kcal/kg DM. Similarly, there was no difference between DY and SBM in the estimated ME (3,431 and 3,756 kcal/kg DM, respectively). Experiment 2 was conducted to determine the standardized ileal digestibility (SID) of AA in DY and SBM. Twenty-one barrows with a mean initial BW of 20.0 kg (SD = 1.31) were surgically fitted with T-cannulas at the distal ileum and assigned to 3 dietary treatments in a randomized complete block design with BW as a blocking factor. Two semi-purified diets containing DY or SBM as the sole nitrogen source and one nitrogen-free diet (NFD) were prepared. The NFD was used to estimate the basal ileal endogenous losses of CP and AA. Pigs were fed the 3 diets for 5 d as adaptation, followed by 2 d of feeding with ileal digesta collection. The SID of AA, except Gly and Pro, in DY were less (P < 0.05) than in SBM. The SID of indispensable AA in DY ranged from 64.1% for Thr to 85.2% for Arg, and those in SBM ranged from 83.9% for Thr to 91.8% for Arg. In conclusion, energy values of DY are not different from those of SBM, whereas AA in DY are less digestible than in SBM. The estimated DE and ME as well as the SID of AA in DY and SBM can be used in diet formulation for growing pigs using these ingredients.

SUMMARYFour Holstein steers (297 ± 56 kg of body weight (BW)) fitted with duodenal cannula and rumen catheter, were housed in metabolism cages and used in a 4 × 4 Latin Square trial to evaluate the effect of both protein source andAcacia mearnsiitannin extract on digestibility, ruminal fermentation, rumen microbial protein synthesis, N utilization and on duodenal flow of individual amino acids. The diet was offered at restricted amount of 25 g of dry matter (DM)/kg BW and consisted of maize silage plus concentrate, in a proportion of 0·7:0·3 (DM basis) respectively. Concentrate was formulated with either soybean meal or canola meal as protein source, with or without 50 g/kg ofA. mearnsiitannin extract (i.e. 15 g/kg of total dietary DM). There was no effect of protein source on most variables. The apparent and true organic matter (OM) digestibilities, as well as neutral detergent fibre (NDF) digestibility were negatively affected by tannin extract inclusion without, however, affecting digestible OM intake. The amount of nitrogen (N) excreted in faeces increased whereas the urinary N excretion decreased in tannin extract treatments. No interaction time × treatment was detected for any rumen variable and no treatment effect was observed for rumen fluid pH and reducing sugars concentration. Rumen fluid concentration of ammonia N was lower for the canola meal plus tannin extract treatment. Rumen concentration ofα-amino compounds was not affected by tannin extract but was higher when canola meal was the protein source. The duodenal flow of OM, total N,α-amino N and non-ammonia non-microbial N increased with tannin extract inclusion, whereas the duodenal flow of microbial N was not affected by treatment. For both protein sources, the amount of most individual amino acids flowing to the duodenum increased due to tannin extract addition. In conclusion, the dietary inclusion of 15 g/kg DM of tannin extract fromA. mearnsiiimproved the amino acid supply independently of whether the protein source was canola meal or soybean meal, without affecting the amino acid profile, to steers fed maize silage plus concentrate, with a minor but significant impact on OM digestibility.

A study was carried out to determine the influence of partial mechanical tail-end dehulling on apparent ileal amino acid (AA) digestibilities and digestible energy content in canola meal (CM) samples for growing pigs. Twenty Landrace × Yorkshire barrows, with an initial body weight of 35 kg, were fitted with a simple T-cannula at the distal ileum. Digestibilities were determined in 12 experimental diets with observations from five pigs per diet. Five batches of regular CM were obtained from five different crushing plants in Western Canada. A fraction of these batches was partially dehulled. The regular and partially dehulled CM samples were included at 20% in a barley-based diet. One pooled high-fiber CM sample and a straight barley diet were evaluated as well. Partial dehulling increased (P < 0.05) the digestible energy (DE) content from 12.2 to 13.3 MJ kg DM−1, respectively, and the level of crude protein (CP) from 40.6 to 43.8% in regular and partially dehulled CM samples, respectively. The digestibility of threonine was increased (P < 0.05) by partial dehulling, from 72.1 to 75.5%; the digestibilities of CP, lysine, methionine and cysteine were not affected (P > 0.05). Only the digestibilities of methionine and threonine were lower (P < 0.05) in the high-fiber CM sample than in the regular and partially dehulled samples. Digestible energy content, which ranged from 10.8 to 14.2 MJ kg DM−1, differed (P < 0.05) between crushing plants for both regular and partially dehulled CM samples. The digestibility of lysine did not differ (P > 0.05) between processing plants for the regular CM samples. The digestibility of lysine did not differ (P > 0.05) between processing plants for the regular CM samples. In contrast, there were differences (P < 0.05) in lysine digestibility, ranging from 74.8 to 83.8%, and methionine, ranging from 80.4 to 86.9%, between crushing plants for partially dehulled samples. There were low negative relationships between apparent ileal AA digestibilities and NDF, ADF and CF levels (r < 0.39) and between DE content and NDF, ADF and CF levels (r < 0.36) in the CM samples. In conclusion, the reduction in fiber content by mechanical tail-end dehulling increased the supply of DE and the level of CP, but did not influence apparent ileal CP or AA digestibilities, except for threonine which was slightly increased.
