Two studies were undertaken to determine the feeding value of high-moisture barley (HMB) for growing swine. HMB containing approximately 25% moisture and dry barley (approximately 13% moisture) was harvested from the same 21.8-ha field. On a dry matter (DM) basis, the HMB yielded 19.6% more than the dry barley. In the first experiment, 56 crossbred gilts and 24 crossbred barrows of an average initial weight of 28 kg were allocated on the basis of initial weight and sex to diets based on either anaerobically stored HMB or dry barley. Pigs fed the HMB-based diet consumed significantly more feed (P < 0.05) on a DM basis, than did pigs fed the dry-barley-based diet. Average daily gain (ADG) and feed conversion efficiency (FCE) were not affected by diet (P > 0.05). In the second experiment, eight barrows (57.6 kg initial weight), fitted with ileal T-cannulas, were used in a replicated 4 × 4 Latin square to determine the apparent ileal digestibilities of nutrients in diets based on ground or rolled HMB (75% DM) and ground or rolled dry barley (87% DM). There were no differences (P > 0.05) among the four treatment groups in the apparent ileal digestibilities of the DM, CP, gross energy, starch or β-glucan components of the diets. The average ileal digestibility coefficient for β-glucan of the four diets was 79.6% (range: 76–82.2%), suggesting that this component is readily digested by growing pigs. The apparent ileal digestibilities for neutral detergent fiber (NDF) and phosphorus were lower (P < 0.05) for the ground dry barley diet than for the other diets. The apparent ileal digestibilities of lysine, methionine, isoleucine, alanine, valine, and aspartic acid were significantly higher (P < 0.05) for the ground HMB diet than for the dry barley diets. However, the digestibility coefficients for lysine, isoleucine, valine, and aspartic acid for the rolled HMB diet tended to be intermediate between the digestibility coefficients of these amino acids for the ground HMB diet and those for the dry barley diet. Thus, earlier harvest, in combination with anaerobic storage generally improves the digestibility of HMB as compared to dry barley.

Almeida, F. N., Htoo, J. K., Thomson, J. and Stein, H. H. 2013. Amino acid digestibility in camelina products fed to growing pigs. Can. J. Anim. Sci. 93: 335–343. Camelina seed production has increased in North America because of demand for camelina oil for biofuel production. Camelina expellers (CE) is the co-product that remains after oil has been expelled, and CE usually contains approximately 35% crude protein (CP), 14% ether extract, 10% crude fiber, and 5% ash making it an attractive feedstuff for livestock. An experiment was conducted to determine the standardized ileal digestibility (SID) of CP and amino acids (AA) in two sources of camelina seeds [CS-1 and CS-2; average: 39% acid hydrolyzed ether extract (AEE), 28% CP, 27% neutral detergent fiber (NDF), 12% acid detergent fiber (ADF), 4% ash] and in three sources of CE (CE-1, CE-2, and CE-3; average: 35% CP, 24% NDF, 15% AEE, 14% ADF, 6% ash) and to compare the SID of CP and AA in camelina products with the SID of CP and AA in solvent-extracted canola meal fed to pigs. Seven growing pigs (initial BW 43.5 kg) were randomly allotted to a 7×7 Latin square design with seven diets fed to individually housed pigs over seven periods. Six of the diets contained CS, CE, or canola meal as the sole source of CP and AA and a N-free diet was used to determine basal endogenous losses of CP and AA. The SID of CP in CS-1 and CE-2 was less (P<0.01) than the SID of CP in canola meal, but the SID of CP in CS-2, CE-1, and CE-3 was not different from the SID of CP in canola meal. The SID of Lys in CS-1 and CS-2 was less (P<0.01) than in canola meal, but the SID of Lys was not different among CE-1, CE-2, CE-3, and canola meal. Results from this experiment indicate that the SID of AA in CE is mostly comparable with that of canola meal, but the digestibility of CP and AA in the two camelina seeds was somewhat less than in CE and canola meal. Camelina expellers may, therefore, be included in diets fed to pigs.

Abstract Dry extruded-expelled soybean meal (DESBM) is an attractive feed ingredient for swine not only as a protein source but also as a good source of energy because of its high fat content. Apparent (AID) and standardized (SID) ileal amino acid (AA) digestibility in DESBM fed without or with organic acid (OA) and a multicarbohydrase (MC) supplementation to growing pigs were determined. Ten ileal-cannulated barrows (17.3 ± 0.4 kg BW) were randomly assigned to 1 of 5 dietary treatments in a replicated 5 × 4 incomplete Latin square design with 4 periods, each consisting of 5 d of adaptation and 2 d of ileal digesta collection. Four cornstarch-based diets with 44.4% DESBM as the only source of AA, without or with OA and MC supplementation, and a 5% casein-cornstarch diet were used. All diets contained 0.3% titanium dioxide. Data were analyzed using the MIXED model procedures of SAS, with the final model including OA, MC, and the interaction between OA and MC as the main effects. The SID of indispensable AA in DESBM fed to growing pigs were: Arg, 93.2%; His, 85.1%; Ile, 87.1%; Leu, 87.6%; Lys, 88.7%; Met, 87.8%; Phe, 88.4%; Thr, 81.4%; Trp, 73.6%; Val, 84.5%. OA supplementation decreased the AID and SID (P &lt; 0.05) of Arg, Ile, Asp, and Glu, and tended (P &lt; 0.10) to decrease the AID and SID of Phe, Trp, Cys, Gly, and Tyr. MC supplementation did not affect the AID and SID of AA, and no interactive effect on AA digestibility was observed between OA and MC supplementation. In conclusion, dietary supplementation of OA and MC showed no positive effects on improving AA digestibility in DESBM fed to growing pigs.

ABSTRACT The objective of this work was to evaluate the effect of increasing levels of guava agro-industrial waste (GAW) on the ingestive behavior of Santa Inês lambs. Forty non-castrated sheep of the Santa Inês breed were used, at an initial weight of 21.33 ± 2.62 kg, and at the age of 120 days, distributed in a completely randomized design, with five treatments and fed with increasing GAW levels (0.0, 7.5, 15.0, 22.5 and 30.0%). The average daily gain (ADG) showed orthogonal contrast (P <0.05), in which the animals that ingested the control diet had lower performances. The animals with GAW added to the diet obtained more significant weight gains reflected by a better feed conversion. Among the variables, idleness, feeding, and total chewing time had a significant effect (P<0.05); animals spent more time idle at the 30.0% inclusion level and less time in the control group. However, the means of the 7.5, 15.0, and 22.5% GAW inclusion levels were statistically similar to the control group and the 30.0% level. There was a significant effect (P<0.05) on feed efficiency, with the lowest values being presented for the control group and the highest values at the 30% inclusion level of GAW. The 30.0% GAW feed for lambs in confinement reduces feed time, and total chewing prolongs idleness and increases feed efficiency without compromising dry matter intake, neutral detergent fiber intake, and ADG.

Abstract Heat treatment could effectively decrease the antinutritional factors in soybean during meal processing. One such progress is the combination of extrusion with expelling, which produces the dry extruded-expelled soybean meal (DESBM), and there is a great interest in exploring its utilization as a dietary ingredient for swine. Thus, eight ileal-cannulated barrows (initial BW = 30 ± 1.3 kg) were used to determine the ileal amino acid (AA) digestibility of DESBM fed to growing pigs with or without multi-carbohydrase (MC) supplementation. Pigs were randomly assigned to 1 of 4 treatments in a replicated 4 × 4 Latin square design to give eight observations per treatment. The experimental diets were formulated to contain one of the two batches of DESBM (DESBM-1 and DESBM-2) as the sole source of protein. All diets contained titanium dioxide (0.3%) as an indigestible marker to calculate nutrient digestibility. Each experimental period lasted for seven days, and ileal digesta samples were collected on d 6 and d 7. The standardized ileal digestibility (SID) of AA were calculated using published mean values to estimate ileal endogenous AA losses. Data were analyzed using the mixed model procedures of SAS, and the final model had treatment, batch, and the interaction between treatment and batch as the main effects. In general, the SID of AA in DESBM-1 and DESBM-2 were not different, such as Ile, Lys, Met, Thr, and Val, which averaged 88.97%, 89.77%, 89.08%, 84.38%, and 86.85% respectively. There were no effects of MC supplementation on AID and SID of AA digestibility in DESBM except for the AID of Trp (P &lt; 0.05). Also, there were no interaction effects of MC supplementation and batch on AA digestibility in DESBM. In conclusion, enzyme supplementation did not improve the AID and SID of AA in DESBM fed to growing pigs.

Abstract Carinata (Brasicca carinata) is an oilseed crop of brassica family that is grown for production of oil for biofuel industry. Expeller-pressed carinata cake (EPCAR), a co-product from carinata seed oil extraction plants, is available for livestock feeding. However, nutritive value of EPCAR for pigs has not been reported. Objective of this study was to determine standardized ileal digestibility (SID) of amino acids (AA) and net energy value of EPCAR for growing pigs. Eight ileal-cannulated barrows (initial BW = 33 kg) were fed 3 diets in a replicated 3 × 3 Latin square design with 2 added columns to give 8 replicates/diet. The diets were cornstarch-based, containing expeller-pressed canola cake (EPCAN) or EPCAR as sole protein source, and N-free. The EPCAN was included in the study for comparison because it is derived from canola, which is the most widely used crop of Brassica family for oil production. Digestibility of AA in feedstuffs was determined by the direct method. Energy digestibility in EPCAN and EPCAR was determined by difference from the N-free diet. On DM basis, EPCAN and EPCAR contained 39.6 and 50.2% CP, 20.7 and 26.8% NDF, 16.0 and 0.88% ether extract, 2.32 and 1.82% lysine, 0.74 and 0.96% methionine, 1.63 and 1.89% threonine, and 0.50 and 0.64% tryptophan, respectively. The EPCAN compared with EPCAR, had greater (PPP = 0.078) in SID of threonine. The EPCAN had greater (P < 0.05) net energy value than EPCAN (2,082 vs. 1,576 kcal/kg DM). In conclusion, EPCAR lower energy value than EPCAN. However, EPCAR had greater SID of most AA than EPCAN; therefore, EPCAR can serve as alternative oilseed co-product feedstuff for pigs.

AbstractThe effects of pantothenic acid (PA) and folic acid (FA) addition on digestibility coefficient, ruminal fermentation and urinary purine derivative (PD) excretion in dairy bulls were evaluated. Eight rumen-cannulated Holstein dairy bulls were allocated to a replicated 4 × 4 Latin square design according to a 2 × 2 factorial arrangement. Diets were supplemented with two levels of FA (0 or 8.0 mg/kg dietary dry matter [DM]) and two of PA (0 or 60 mg/kg DM). The PA × FA interaction was not significant for all variables. Both supplements increased DM intake and average daily gain, but decreased a feed conversion ratio. Digestibility of DM, organic matter, crude protein and neutral detergent fibre increased, but ether extract digestibility was unchanged for both supplements. Digestibility of acid detergent fibre only increased with FA supplementation. For both supplements, ruminal pH and ammonia nitrogen (N) decreased, but total volatile fatty acid (VFA) concentration increased. Acetate proportion only increased with FA supplementation. Propionate proportion decreased for both supplements. Consequently, the acetate to propionate ratio increased. For both supplements, activity of xylanase and pectinase, population of Ruminococcus albus, R. flavefaciens, Fibrobacter succinogenes and Ruminobacter amylophilus and total PD excretion increased. Additionally, activity of carboxymethylcellulase, cellobiase, α-amylase and protease, and population of total bacteria, fungi, protozoa, methanogens, Butyrivibrio fibrisolvens and Prevotella ruminicola increased with FA addition. The results suggested that PA and FA supplementation stimulated ruminal microbial growth and enzyme activity, resulting in an increased digestibility coefficient and ruminal total VFA concentration in dairy bulls.

Three factorial experiments were conducted to determine the relative feeding value of dry barley (DB) and high-moisture barley (HMB), and to evaluate the influence of method of ensiling (Pit vs. Harvestore® (HAV) silo), source of roughage (hay vs. silage), and level of concentrate (90 vs. 75%) on the performance and carcass characteristics of feedlot cattle. In exp. 1, 252 steers (initial wt 357 kg) were assigned on the basis of weight to six treatments (two pens × 21 animals per pen). A mixed diet consisting of 85.2% barley grain (dry matter (DM) basis) was offered free choice. The barley portion of the ration consisted of either 0, 25, 50, 75 or 100% DB with the balance being HMB from a pit silo. The sixth treatment consisted of feeding 100% HMB for the first 57 d and 100% DB for the remainder of the trial. Overall average daily gain (ADG) for steers fed 100% DB (1.70 kg d−1) was significantly higher than observed for animals fed 100, 75 or 50% HMB (1.46, 1.49 and 1.56 kg d−1, respectively). The kg of feed DM required per kg gain (FC) varied between 5.76 and 7.13 and was not (P > 0.05) influenced by treatment. No differences (P > 0.05) were observed in carcass characteristics. In exp. 2, 360 steers (initial wt 340 kg) were allotted on the basis of weight to six treatments designed to evaluate the effect of source (Pit vs. HAV) and level of HMB, in diets containing 10.2% silage, on animal performance. Overall ADG (1.11 – 1.17 kg d−1), FC (6.66 – 7.01) and carcass characteristics were similar (P > 0.05) for animals fed Pit HMB, HAV HMB and DB. In exp. 3, 264 weanling calves (initial wt 216 kg) were allotted on the basis of weight to six treatments which differed in type of barley (HMB vs. DB), source of roughage (hay vs. silage) and level of concentrate (75 vs. 90%; DM basis). The feeding period was 127 d. Daily gains varied between 0.78 and 0.91 kg d−1 and FC ranged from 6.40 to 7.10 and were not influenced (P > 0.05) by source of barley or source or level of roughage. While animals fed DB had significantly higher ADG than those fed HMB in exp. 1, the overall results from the three experiments indicate that on a DM basis HMB has similar feeding value to DB, and that there is no major difference between Pit and HAV-stored HMB for feedlot cattle.

Five Holstein cows were distributed in a 5x5 latin square design to assess the effect of replacement levels of dry ground corn grain (DGCG) by high moisture corn silage (HMCS) on intake, total nutrient digestibility and plasma glucose, according to the following treatments: 1) 100% DGCG; 2) 75% DGCG and 25% HMCS; 3) 50% DGCG and 50% HMCS; 4) 25% DGCG and 75% HMCS; 5) 100% HMCS. The experiment lasted 70 days, divided into five phases of 14 days each. The digestibility was obtained using chromic oxide (Cr2O3) as the indicator. Fecal samples were collected twice daily and blood samples were collected on the last day of each period before the first meal (0h) and 2h, 4h, 6h and 12h after the meal. There was no effect (P>0.05) on the intake of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch. The total apparent digestibility of DM, crude protein (CP), NDF and ADF were not affected (P>0.05) by the treatments, as well as the plasma glucose concentration. However, there was a decreased linear effect (P<0.05) for the protein intake and increased linear effect (P<0.05) for starch digestibility, as the level of HMCS was increased in the diets.

SUMMARYA total of 156 pigs of the Large White breed were used in a series of four experiments to test the suitability of barley which had been stored with a high moisture content as an ingredient in the diets of growing pigs. Barleys with mean moisture contents of 26·3%, 28·1% and 21·2% and a range from 19·6% to 30·5%, from three successive harvests were used.In all the trials there was evidence that the use of moist barley in diets for growing pigs had an adverse effect on live-weight gain and feed conversion ratio, the effect being independent of whether feed intakes were equated on the basis of the dry-matter content of the diets. In one of the experiments performance was depressed to the extent of causing changes in carcass characteristics. The performance of pigs given rolled barley was similar to that of others given ground barley.

Buckwheat (Fagopyrum esculentum) was evaluated alone or with 25, 50, 75 or 100% replacement by wheat (W) or barley (B) in 16% protein diets fed to 72 crossbred pigs from 20 to 60 kg liveweight. Pigs were randomly alloted two per pen, within sex, and housed in confinement on partially slatted concrete floors. Daily feed consumption (1.89–2.27 kg/day), average daily gain (0.66–0.72 kg/day) and feed/gain (2.79–3.18) did not differ significantly (P < 0.05) between treatments. At 50% replacement of the buckwheat (BW) more feed (P < 0.05) was consumed (2.22 kg/day) than at 25 or 100% replacement levels (1.99 and 1.92 kg/day, respectively). More DE was consumed per kilogram of gain (DE/gain) (P < 0.05) by wheat-fed pigs than by barley-fed pigs (40.0 vs. 38.2 MJ DE/kg, respectively). The 50% substitution of either grain (42.1 MJ/kg) resulted in more DE/gain (P < 0.05) than observed on the BW only diet (37.1 MJ/kg). Two 4 × 4 latin square designs, with eight pigs initially weighing 40 kg, were used for determination of digestibility of dry matter (DM), crude protein (CP) and gross energy (GE) in BW, W or B individually and in blends of BW and either W or B. Coefficients of digestibility for CP were 72.7%, 81.6% and 65.5% and for GE were 65.4%, 80.2% and 71.1% in BW, W and B, respectively. Blends of BW and W had digestibility coefficients for DM, CP and GE between the values determined for the grains individually but those determined for mixtures of BW and B were lower than expected based on coefficients determined for the grains individually. Buckwheat used contained 12% CP, 0.68% lysine, 12.3% acid detergent fiber on as fed basis and 9.6% digestible protein and 11.98 MJ of DE per kilogram dry matter. Key words: Buckwheat, pigs, digestibility, growth, mono-cereal diets
