The possibility that supplemental trace minerals (TM) might be less available in the presence of canola meal (CM) compared with other protein sources was investigated using growing rats fed a barley-wheat (BW) diet alone or with 20% added CM, soybean meal or ammoniated mustard meal for 28 d. A purified diet was used as a control diet. Femur Zn concentrations were lowest (P < 0.05) in rats fed the BW + CM diet (306 μg g−1femur ash) followed by the BW diet (329 μg g−1); both groups showed lower Zn levels than for all other diets (control diet 345 μg g−1). Plasma Zn concentrations were lowest (P < 0.05) in rats fed the BW + CM diet (1.07 vs. 1.35 μg mL−1 for control diet). Differences in concentrations of copper, iron or manganese in plasma and liver were minor. Apparent absorption of Zn from the BW and BW + CM diets tended to be less than from the other diets. Some differences were observed in weight gains and feed efficiency but were apparently unrelated to a TM deficiency. The results indicated that while dietary levels of copper, iron and manganese were adequate, there was evidence of a marginal deficiency of Zn particularly in the BW + CM diet, a result of reduced availability of supplemental Zn due to the CM in the diet.

Naked Oats

The yolk lipid composition was determined and the sensory and internal quality evaluated for eggs obtained from hens at 8 and 15 m of age from two experiments. In exp. 1, in which naked oats replaced corn and soybean meal at levels of 0–800 g kg−1, there was a marked decrease in Roche yolk color at 8 mo, an increase in egg weight, and at 15 mo and a decrease in yolk flavor intensity with increasing level of oats. In exp. 2, there were four diets (0) a corn-soybean meal control, (876) a soybean-free naked oat alfalfa diet, (874) diet 876 supplemented with lysine and methionine and (691) diet 876 supplemented with canola meal. Haugh units were greater and yolk color less for supplemented naked oat diets versus the control diet. The yolk lipid content of sphingomyelin and sterols were higher than for the control diet. A yolk sulfury aroma was noted at 15 mo. At 8 mo, egg Haugh units were lower for the unsupplemented oat diet relative to the corn-soy diet. There were no other detrimental effects of oat diet on egg sensory quality. Other than a corrigible yolk color effect, egg quality traits do not limit the use of naked oats in poultry layer diets.

Abstract Background The aim of this study is a comparison between some different protein sources in sheep rations to identify the best protein source that achieves the highest production performance and the lowest economical feed efficiency. Twenty Farafra male lambs weighed on average 41.39 ± 1.66 kg were divided randomly into four similar groups of 5 animals each. All groups were fed on concentrate feed mixture (CFM) at 3% of their body weight, and wheat straw fed ad lib. to replace 100% of the soybean meal (SBM) as a source of protein, black cumin seed meal (BCSM), cottonseed meal (CSM) and sesame seed meal (SSM) were incorporated into the CFM. The feeding trial extended for 66 days followed by digestibility and nitrogen (N) balance trials. Results The results indicated no difference in total feed intake between experimental groups. Digestibility of crude protein, ether extract and crude fiber for animals fed CSM ration was higher (p < 0.05) than those fed the other rations. On the other hand, the CSM ration recorded a higher value of digestible crude protein than SBM and BCSM rations. Lambs gave rations containing CSM was higher (p < 0.05) average daily weight gain compared with those fed the other rations. Lambs that fed CSM ration were better to feed conversion as kg dry matter intake/kg gain than those fed the other rations. Relative economic efficiency was the best for CSM ration as compared to other protein sources. Nitrogen balance value of sheep fed CSM diet had the highest (p < 0.05) value compared with those fed different sources. Rumen fermentation showed that the pH value was the lowest with SSM, NH3-N concentration was higher for BCSM and SSM, and total volatile fatty acids were higher for SBM compared with the other rations. Conclusion It could be concluded that cottonseed meal was the best treatment for digestibility coefficient, average daily gain, highest nitrogen balance, better feed conversion ratio and also the best economic efficiency compared to soybean meal, black cumin seed meal and sesame seed meal treatments. It can replace 100% soybean meal by cottonseed meal in sheep ration when economics is to be considered.

Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the to asted meal (1.01 vs. 15.58 µmol g-1). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g-1), 2-OH-3-butenyl (5.47 µmol g-1) and 4-OH-3-methylindoyl (4.68 µmol g-1). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal.

Abstract Cecal inoculum collected from broilers fed a diet supplemented with xylanase showed increased gas production in an in vitro fermentation study with arabinoxylan-based substrates, indicating that intestinal microbiota can adapt to increase the capability to ferment arabinoxylans when pre-exposed to xylo-oligosaccharides (XOS) produced by xylanase. As the most abundant non-starch polysaccharides in a corn-soybean meal-based diet is arabinoxylan, this study tested the hypothesis that a blend of a xylanase and XOS will improve growth performance of pigs compared with those fed a diet supplemented with xylanase alone. One hundred twenty male crossbred (Landrace x Large white x Duroc) pigs (77 days average age; 30 kg average body weight -BW) were allocated to one of three treatments: CTR (control diet), XYL (CTR diet supplemented with 100 g/t of xylanase [Econase XT, AB Vista]) and XYL+XOS [CTR diet supplemented with 100 g/t of xylanase and XOS (Signis, AB Vista)]. Each treatment had ten replicates, with 4 animals each. The control diet was formulated with corn, soybean meal, DDGS and cassava meal as major ingredients. Pelleted diets were fed over 3 phases: grower (30–60 kg), finisher 1 (60–80 kg) and finisher 2 (80–100 kg). Average daily gain (ADG) and daily feed intake (ADFI) were measured from 30 to 100 kg and feed efficiency calculated (FCR). No treatment effects were observed on ADFI. Pigs offered the XYL+XOS had increased ADG (CTR = 1.058 vs XYL+XOS= 1.086 g/pig/d; P = 0.02) compared with those supplemented with xylanase alone (CTR = 1.058 vs XYL = 1.067 g/pig/d; P = 0.40). Feed efficiency was improved with XYL (2.65; P = 0.042) and XYL+XOS (2.60; P < 0.001) compared with CTR (2.71). These results suggest that xylanase in combination with XOS further improves daily gain and FCR compared with a xylanase alone. Interestingly the differences between XYL and XYL+XOS become more apparent in older animals, when the microbiome matures and possibly digests fiber more effectively.

Experiments were earned out with sheep and in vitro to evaluate isobutyraldehyde monourea (IBMU; propanal-2-methyl-monourea) as a slow-release nitrogen source for ruminant animals. Examination of the compound for carbon, hydrogen, and nitrogen composition and infrared, NMR and mass spectral analyses indicated that IBMU was present in significant amounts. Ten sheep were randomly assigned to diets containing bromegrass hay and corn grain and the following nitrogen supplementation treatments: (1) control, (2) urea, (3) soybean meal, (4) canola meal and (5) IBMU, with the protein supplements providing approximately 25% of the nitrogen intake. Similar treatments were also prepared and evaluated in vitro, with the exception that wheat straw rather than bromegrass hay was used in the incubation. The digestibility of nitrogen in the ration containing IBMU was higher (P < 0.05) than its digestibility in the other rations when measurements were conducted with sheep over three 14-d periods. No differences in dry matter (DM) or energy digestibility were detected between the different treatments. The digestible energy content of IBMU was estimated to be greater than 21 MJ kg−1. The digestibilities of DM in vitro after 2, 4, 8, 12, 24, 48 and 72 h of incubation were not influenced by the presence of IBMU. No influence of nitrogen supplementation on nitrogen balance was observed, probably because of the high protein content of the control ration (10.6%). IBMU exhibited the characteristics of an ideal slow-release nonprotein nitrogen supplement, since concentrations of rumen ammonia nitrogen did not vary from 0 to 8 h after feeding and ammonia concentrations were higher (P < 0.05) both before feeding and 8 h after feeding when IBMU was fed than when any of the other supplements were fed. The concentration of isobutyric acid averaged 2.6-fold higher when IBMU was fed than when canola meal or soybean meal was fed, confirming that most of the compound was degraded in the rumen. Sheep fed IBMU had lower concentrations of acetic, propionic and butyric acid in the rumen than those fed natural protein supplements. It was unclear whether the decrease in VFA concentration was positive or negative in terms of nutritional value. It was concluded that IBMU exhibited some ideal characteristics for a nonprotein nitrogen supplement for ruminant animals because it was degraded at an optimum rate in the rumen and provided rumen microflora with isobutyric acid. Further experimentation is warranted to determine its usefulness when nitrogen-deficient diets are fed to ruminant animals.

Abstract β-Mannans are strongly anti-nutritive polysaccharide fibres found in most vegetable feed ingredients. The objective of the study was to compare piglet performance and antibiotic use between a Control group, fed a conventional 2-phase diet, and an Enzyme treated group, fed an adapted 2-phase diet including a β-mannanase enzyme (Hemicell™ HT; Elanco). A seven-week feeding trial was conducted with 320 pigs in two rotations of 160 piglets in 20 replicate pens of 8 pigs. Two different 3-phase diets were compared: a standard 3-phase control diet and an adapted 3-phase diet including a β-mannanase enzyme included at 300 g/tonne. The following adaptation were made: Phase-1 (weeks 1–3): 0.15% potato protein concentrate and 2.00% Danex [extruded soybean meal (SBM)], was replaced with SBM 48%, Phase-2 (weeks 4–7): β-mannanase was formulated to replace 63 kcal/kg NE. Standard piglet performance parameters (ADWG, ADFI, FCR) and antibiotic use were recorded. All data analyses were performed using R version 3.6.3 (R Core Team, 2020). All tests were performed at the 5% level of significance. When multiple testing was involved, the nominal 5% Familywise Error Rate (FWER) was used. Throughout the trial and within each phase, ADWG, ADFI and FCR were not significantly different (P &gt; 0.05) between Control and Enzyme group. No mortality occurred and no antimicrobials were used in either of the treatment groups. Inclusion of a β-mannanase in nursery diets with an adapted formulation, by replacing expensive protein sources by soybean meal, or reducing the NE content by 63 kcal/kg, resulted in similar piglet performance post-weaning with reduced mortality and less antimicrobials used.

A 60 days feeding trial was conducted to investigate partial replacement of fishmeal (FM) with either soybean meal (SBM) or distillers dried grain solubles (DDGS) as alternative protein sources for milkfish, Chanos chanos fingerlings. Nine experimental diets were formulated with either fishmeal or with two alternative protein sources such as SBM or DDGS at three protein levels (35, 40 and 45%). Milkfish fingerlings (270 nos.) with mean length and weight of 5.24±0.03 cm, 1.25±0.05 g were selected for the study and in total there were 9 treatments in triplicates. The experimental diets were: F35 (35% CP - FM diet), F40 (40% CP - FM), F45 (45% CP - FM), FS35 (35% CP - FM + SBM), FS40 (40% CP - FM + SBM), FS45 (45% CP - FM + SBM), FD35 (35% CP - FM + DDGS), FD40 (40% CP - FM + DDGS), FD45 (45% CP - FM + DDGS). Diets incorporated with fishmeal alone served as control diet for this experiment. We observed that, final weight was significantly (p<0.05) higher for fishmeal based diet irrespective of the crude protein level. The same trend was observed for body weight gain for FM based diet. Specific growth rate (SGR) was found to be more than 2% per day for all the experimental diets fed fish and FD45 showed the lowest SGR compared to other treatment groups. Similarly FD45 had poor feed conversion ratio (FCR) when compared to other dietary groups. Survival rate of the fingerlings was found to be significantly higher for all FM diets (80%), FS35 (80%) and FD35 (80%) diet fed groups, whereas FD45 dietary group showed significantly lower survival rate (60%). Higher amylase activity was observed in F40 diet, higher lipase enzyme activity in FS 35 diet, while higher protease activity was recorded in F35 diet and the values showed significant difference (p<0.05) between different treatment groups. Results of the study, clearly indicate that soybean meal (FS35) could be used to partially replace the fishmeal in the diet of milkfish fingerlings.

Supplementing a 15% protein diet for chickens, with all the protein coming from canola meal, with essential amino acids (EAA) to bring diet levels up to those recommended by NRC, failed to improve weight gain over that of an unsupplemented canola meal diet. While feed:gain ratio of the EAA-supplemented diet was improved, performance was markedly inferior to that of a 20% protein corn-soybean meal diet. Supplementing the canola meal basal diet with corn oil, lysine, or lysine plus arginine resulted in significant responses; however, performance was again far below that of the corn-soybean meal positive control diet. Supplementing the canola meal basal with EAA to bring levels up to close to the corn-soybean meal control diet resulted in performance which was superior to that obtained in the experiments in which EAA were supplemented to NRC requirement levels. However, performance was still markedly inferior to the corn-soybean meal control diet. A point of interest was the failure to demonstrate a need for methionine supplementation of the canola meal diet, even though by calculations it should have been deficient in this amino acid. A marked improvement in performance occurred when the level of methionine supplementation was reduced from 0.28 to 0.1% for the canola meal diet, supplemented with lysine, arginine and tryptophan. This clearly demonstrates that excess methionine or sulphur supplementation can markedly alter the performance of canola meal diets and may be one of the major reasons why EAA supplementation of semipurified diets that contain canola meal has failed to result in marked improvements in performance.
