Abstract Two experiments were conducted to evaluate the digestible energy (DE), metabolizable energy (ME), and standardized ileal digestibility (SID) of amino acids (AA) in dried yeast (DY) and soybean meal (SBM) fed to pigs. In Exp. 1, 30 barrows with an initial body weight (BW) of 20.7 ± 1.01 were assigned to 5 diets in a randomized complete block design with period and BW as blocking factors. A basal diet was prepared to contain corn, canola meal, and soybean oil as energy-contributing ingredients. Four additional diets were prepared by adding 5 or 10 g/kg DY or SBM at the expense of energy-contributing ingredients in the basal diet to estimate the DE and ME in test ingredients by regression analysis. On a dry matter basis, estimated DE and ME in DY were 4,022 and 3,352 kcal/kg, respectively, and those in SBM were 3,876 and 3,601kcal/kg, respectively. There was no difference in estimated DE or ME between DY and SBM. In Exp. 2, 21 barrows (initial BW = 20.0 ± 1.31 kg) surgically fitted with T-cannulas at the distal ileum were assigned to 3 diets in a randomized complete block design with BW as a blocking factor. Two diets were prepared to contain DY or SBM as the sole source of nitrogen, and a nitrogen-free diet was prepared to determine the basal ileal endogenous losses of AA. The SID of AA, except for Gly and Pro, in SBM were greater (P < 0.05) than in DY. The SID of indispensable AA in DY ranged from 64.7% for Thr to 86.1% for Arg, whereas those in SBM ranged from 84.8% for Thr to 92.3% for Arg. In conclusion, energy values in DY was comparable with SBM, but the SID of most AA in DY were less than in SBM.

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.

Supplemental Protein

There is evidence that alpacas derive most of their glucose for energy from the deamination of amino acids. Consequently, they may have an insufficient supply of amino acids to meet their requirements for fibre growth. To optimise fibre production, it may be necessary to supply alpacas with supplemental protein to meet their requirement for extra amino acids. In this study, we examined if the proportion of rumen-degradable dietary protein (RDP) to undegradable dietary protein (UDP) from canola meal influenced the fibre growth of alpacas. We hypothesised that alpacas fed at maintenance a diet containing canola meal protein high in UDP would produce more fibre and spend less time urinating than peers fed a similar amount of canola meal protein with a low proportion of UDP. Four groups of eight alpacas were fed diets with the following ratios of UDP : RDP: 0 : 100, 30 : 70, 60 : 40 or 100 : 0 from canola meal protein. The fibre growth of the animals was measured over 2 months and the behaviour of the animals in the two extreme groups (0 and 100% UDP) was measured over 5 days. The alpacas fed the 0% UDP diet produced fibre of finer diameter than the alpacas fed diets containing higher levels of UDP (P = 0.039) and the 0% UDP group also spent more time urinating (P = 0.027). This result suggests that alpacas may have a limited ability to recycle nitrogen to the fermentative chambers of their stomach when fed a diet low in UDP. Consequently, microbial protein synthesis in the fermentative chambers may have limited the supply of amino acids available to the alpacas.

Metabolisable Energy

Two experiments were conducted to evaluate the nutritional value of four cultivars (Santana, Miami, Courier and Rex) of peas (Pisum sativum L.) for broilers. In Experiment 1, the apparent metabolisable energy (AME) and the apparent ileal amino acid digestibility of these four cultivars were determined. The cultivar effects were found to be not significant (P > 0.05) for the AME and apparent ileal digestibility of amino acids, with the exception of arginine, which was lower (P < 0.05) in Courier than other cultivars. In Experiment 2, using the energy and digestible amino acid values determined in Experiment 1, diets containing 200 g/kg of the four cultivars of peas were formulated and the effects of feeding these diets on the performance and digestive tract development of broiler starters was investigated. Weight gain, feed intake and feed per gain of broiler starters fed diets containing peas were similar (P > 0.05) to those fed the maize-soybean meal diet. In general, the digestive tract development was unaffected (P > 0.05) by the inclusion of peas. The excreta scores of birds fed diets based on Santana, Miami and Rex were similar (P > 0.05) and that of the Courier-based diet was lower (P < 0.05) than those fed the maize-soy control diet. These results suggest that peas are good sources of metabolisable energy and digestible amino acids, and that they can be included at 200 g/kg level as a partial replacement for soybean meal in broiler starter diets without adverse effects on performance.

Daily Gain

Two experiments were conducted to evaluate the replacement value of canola meal (CM) for soybean meal (SBM) in isoenergetic isonitrogenous diets for young pigs between 6 and 20 kg liveweight. Diets utilized wheat, barley, oat groats and blended animal fat as energy sources and evaluated CM at levels from 0 to 100% replacement of SBM. Regression analyses of the results of both experiments indicated that for every 1% addition of CM in the diet, there was a corresponding decrease in average daily feed intake (ADF) and average daily gain (ADG) of 4 and 2 g, respectively. Digestibility coefficients of dry matter and nitrogen were not significantly affected by the level of CM in the diet. Key words: Starter pig, canola meal, soybean meal, protein supplement

The rumen degradability and postruminal digestion of rumen escape dry matter (DM), nitrogen (N) and metabolically essential amino acids (EAA) for canola meal (CM) from five different processing plants (samples 1–5) and one sample of soybean meal (SBM) were compared. Rumen degradability was estimated by incubating sample-filled small nylon bags in situ in the rumen of steers for 0, 4, 8, 12, 16 and 30 h. Postruminal digestion was estimated using a sequence of ruminal in situ incubations for 0, 4, 8, 12 and 16 h, in vitro incubation in an acid-pepsin solution and a mobile nylon bag technique distal to the abomasum. The rumen escape of nutrients for CM1 was consistently lower compared to other CM samples, while CM4 resulted in the highest escape of nutrients at 30 h. An estimate of maximum degradability of EAA measured at 30 h differed among CM samples, with the rumen escape of EAA being CM4 > CM2 = CM5 ≥ CM1 = CM3 > SBM. The DM, N and EAA content of mobile bag residues was relatively uniform among CM samples, particularly after 12 and 16 h of ruminal fermentation, but was higher for CM than for SBM, probably due to a low digestibility of CM hulls. The rumen degradability of CM from different processing plants differed and as a consequence the postruminal digestion of nutrients in CM differed.

Net Protein

Feather meal when used as the sole source of protein in a ration would not support weight gain in growing chicks. Supplementation of feather meal protein with the essential amino acids, in which it is reported deficient, improved rate of gain, but did not improve net protein utilization. One may thus conclude that besides being in imbalance, the protein of feather meal is poorly absorbed.Four commercially available meat meal samples were markedly enhanced by supplementation with the amino acids in which previous work had indicated that meat meal protein was deficient. Meat and feather meal protein when used to supply 3% of the protein in practical-type corn–soybean meal rations gave equally as good results as soybean meal protein. The results obtained using feather meal protein in practical-type rations can not be explained entirely on the basis of excess protein in these diets.
