Ammoniated mustard meal (MM) was prepared in a pilot plant by expelling and hexane-extracting brown mustard seed (Brassica juncea (L.) Coss.) and applying steam, ammonia and water in the desolventizer. Barley-wheat (2:1)-based diets containing MM (16.8%) or MM + lysine (0.20%) or MM + lysine + isoleucine (0.1%) were compared to similar diets containing soybean meal (15.3%) or canola meal (21.6%). Each diet was fed to eight crossbred barows between 24 and 52 kg liveweight. Chemical scores indicated that the unsupplemented MM diet was first- and second-limiting in lysine and isoleucine, respectively. Compared to the unsupplemented MM diet, supplemental lysine significantly improved the feed:gain ratio (2.80 vs. 2.51) while adding both lysine and isoleucine improved daily gain (574 vs. 684 g/day). Lysine and isoleucine supplementation resulted in significant increases in serum concentrations of these amino acids, confirming observations made regarding gains and feed:gain ratio. The isoleucine deficiency associated with MM-supplemented diets may be nutritionally important only in the early part of the grower phase. However, lysine supplementation appears to be necessary throughout the grower period. Key words: Mustard meal, ammoniation, feeding trial, serum amino acids, lysine, isoleucine

Mustard meal was prepared in a pilot plant by expelling and hexane-extracting brown mustard seed (Brassica juncea (L.) Coss.). Steam, ammonia and water were applied during the final stages in the desolventizer. Ammoniated mustard meal (MM) was compared in a swine feeding trial (60 pigs, 25–100 kg) with canola meal (CM; low glucosinolate rapeseed meal), with MM in three combinations with CM and soybean meal (SBM) and with CM + SBM as the protein supplements in six barley:wheat (2:1) diets. Each diet was also fed with and without 0.15% supplementary lysine until pigs weighed 54 kg. Pigs were penned in groups of four and individually fed. Digestibility was determined separately. Ammoniation reduced glucosinolates by over 80% and reduced lysine by 20% but increased crude protein from 44.6 to 51.1%, dry basis. Digestibility values of energy and protein in MM were 72 and 75%, respectively. Digestible energy (10.5% moisture, air-dry basis) was 13.0 MJ/kg and digestible crude protein was 30.25%. Daily gain, daily feed intake and efficiency of feed utilization were poorer with pigs fed MM as the only protein supplement than with pigs fed any other supplement.

Protein metabolism and utilization, and performance were examined in pigs kept on diets with two protein levels, 15 and 17 % crude protein(cp), and supplementation with free L-lysine and DL-methionine. In the 5 x 5 Latin square balance trial, 15 and 17 % cp diets were fed with and without supplementation with 2 g lysine/kg feed and one 15cp diet with both lysine and 0.7 g methionine. The diets had 120 and 136 g DCP/FU, lysine 7.8, 9.4 and 11.0g/kg and sulphur amino acids 4.4, 5.0 and 5.1 g/kg. Nitrogen retention was 13 % higher on the 17 % cp diet than on the 15 % cp diet (P > 0.05). The lysine supplementation improved N retention by 4.3 % on the 15 % cp diet and supplementation with the two amino acids improved it by 2.5 % (P > 0.05 %). Urinary urea excretion on the 17 % cp diet was 17—12 %higher than on unsupplemented 15 % cp diet, and on the diets with amino acid supplementation it was 7—8 % lower (P < 0.05) than on the diets without. In the first feeding trial with 500 pigs, the higher-protein diet gave 7.4 % better daily gains. The diet with 15 % cp supplemented with lysine gave only 2.3 % better gains than the basal 15 % cp diet. The difference in feed conversion efficiency (FCE) between protein levels was statistically significant (P < 0.05). The second feeding trial was a comparison of 17 % and 15 % cp diets in which the lysine and sulphur amino acid levels had been equalized by supplementing the 15 % cp diet with lysine and methionine. The pigs were fed on a grower diet with 18 % cp to 50kg live weight and afterwards the experimental diets were fed separately to the gilts and castrates. The pigs grew similarly on the two diets, 783 vs. 780 g daily. The FCE was better on the lower-protein diet and lower in the gilts then the castrates. The gilts gave better carcase quality than the castrates and the lower-protein diet tended to give better carcase quality. The rather poor response to supplemental free amino acids in the present study seems to indicate limitation of inadequate supply of other amino acid.

Oil-extracted meals from Westar (WCM) and triazine-tolerant (TCM) canola seed (B. napus) were fed at levels of 0, 10, 20 and 30% of the diet to seven barrows of 35 kg initial weight in digestibility trials conducted in four successive replicates. The digestion coefficients for energy were 66 and 69%, respectively, and for crude protein were 76 and 80%. The corresponding digestible energy values were 13.31 and 13.96 MJ kg−1, respectively, and the digestible crude protein values were 32.6 and 37.5%, indicating that the WCM sample was inferior to the TCM sample. The meals were compared in a feeding trial involving 80 pigs housed in groups of four but fed individually from 23 to 100 kg liveweight. Five protein supplement combinations (soybean meal alone (control) and WCM or TCM replacing 50 or 100% of the soy protein) were tested in barley:wheat (2:1) diets with or without supplemental lysine (0.15–0.18%) and fed in meal or pellet form to male and female pigs. There were no significant differences among meals tested in average daily gain in either the growing (0.74 kg) or the finishing period (0.81 kg) but efficiency of feed utilization during the grower period (23–57 kg) was better with soybean meal diets than with the CM diets. Lysine supplementation improved daily gains from 0.70 to 0.77 kg in the grower period and from 0.79 to 0.83 kg in the finisher period. The corresponding improvements in feed:gain ratios were from 2.89 to 2.66 and from 3.75 to 3.62. Pelleting improved daily gain from 0.75 to 0.80 kg and feed:gain from 3.39 to 3.18, over the 23- to 100-kg weight range. Key words: Canola meal, Westar, triazine-tolerant, pigs, feeding trial

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 &lt; 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.

AbstractA total of 384 piglets from a three-way cross Yorkshire ♂ × (Finnish Landrace ♂ × Dutch Landrace♀) ♀ in the live-weight range of 11 to 25 kg were used in a feeding trial. The effect of supplementary microbial phytase from Aspergillus niger var. Van Tieghem on performance (average daily gain (ADG), average daily food intake (ADFI) and food conversion ratio (FCR)) and apparent digestibility of total phosphorus (P), in comparison with a non-supplemented basal diet or a diet supplemented with one or two levels of monocalcium phosphate (MCP), were studied.The piglets were allotted to 12 blocks. Within each block, four experimental diets were offered ad libitum for a period of 4 weeks i.e. (1) basal diet; (2) basal diet + 1·0 g P, from MCP per kg diet; (3) basal diet + 1·9 g P, from MCP per kg diet; and (4) basal diet + 1450 phytase units (PTU) per kg diet. The diets, with added chromium III oxide as a marker, were cold pelleted without steam at a temperature not above 60°C to avoid a possible inactivation of the phytase. In all diets the ratio calcium: digestible P was intended to be constant.Adding 1450 PTU of Aspergillus niger phytase enhanced the apparent digestibility of P by proportionately 0·216 when compared with diet 1 and by proportionately 0·100 compared with diet 3. In addition, significantly higher ADG and ADFI and better FCR were noted in pigs receiving supplementary microbial phytase than in pigs on any other treatment. The content of digestible P of the diet with added phytase, however, zvas between the two levels of the diets with added MCP.

Abstract The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM). Six barrows with an initial body weight of 30.9 ± 2.6 kg fitted with a T-cannula in the distal ileum were assigned to a 6 × 6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole source of AA and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for 4 and half days, and the 3 diets containing AA mixture were switched to the respective diets without AA mixture during the following 2 and half days. Ileal digesta were collected during the last 2 days. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Arg and Trp in corn (P &lt; 0.05), but did not affect that in SBM. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (P &lt; 0.05), but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of AA mixture during the adaptation period. In conclusion, the addition of amino acid during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in feed ingredients.

The possibility that marine invertebrates might obtain part of their nutritional requirements by direct absorption of dissolved molecules through the epidermis has recently received considerable attention. This revival of interest in a field which had been virtually abandoned since the early part of the century was led by the findings of Stephens & Schinske (1957, 1958, 1961). Modern analytical techniques have revealed that the amount of dissolved nutrients in coastal waters is much greater than was formerly realized; total amino acids have been recorded in concentrations of up to 10-4 mole/litre in south-east Alaskan waters (Schell, 1974) and 7 x 10-5 mole/litre off Helgoland (Bohling, 1970). Direct absorption of amino acids has been conclusively established in several phyla (see reviews by Stephens, 1968,1972), and one of the major aims of current research is to show that dissolved organic molecules taken up from available concentrations could be of nutritional significance. Recent developments concerning the possible roles of uptake in marine ecosystems have been reviewed by West, de Burgh & Jeal (1977).
