  • Energy Concentration and amino acid digestibility in high protein canola meal conventional canola meal and in soybean meal fed to growing pigs
    Animal Feed Science and Technology, 2016
    Co-Authors: N W Jaworski, O J Rojas, H H Stein
    Abstract:

    Two experiments were conducted to determine digestible Energy (DE) and metabolizable Energy (ME) and the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein and amino acids in high protein canola meal (CM-HP), conventional canola meal (CM-CV), and soybean meal fed to growing pigs. In Exp. 1, 32 barrows (initial body weight: 47.3 ± 6.2 kg) were housed in metabolism cages and randomly allotted to one of four diets with eight replicate pigs per diet. A corn-based diet (973 g/kg corn) and three diets that contained both corn and each of the two sources of canola meal or soybean meal were formulated. Feces and urine were collected for 5 days after a 5-day adaptation period. The DE and ME values were 14.40 and 13.84 MJ/kg in corn, 12.43 and 10.34 MJ/kg in CM-HP, 11.02 and 9.65 MJ/kg in CM-CV, and 15.63 and 14.13 MJ/kg in soybean meal, respectively. The DE and ME were greater (P < 0.05) in corn and soybean meal than in CM-HP and CM-CV, but the DE and ME were not different between CM-HP and CM-CV. In Exp. 2, eight barrows (initial body weight: 46.4 ± 5.6 kg) were equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 4 × 4 Latin square design with 4 diets and 4 periods in each square. A N-free diet and three cornstarch based diets that contained CM-HP, CM-CV, or soybean meal as the sole source of amino acids were formulated. Each period lasted 7 days and ileal digesta were collected on day 6 and 7 of each period. The AID and SID of crude protein and most amino acids in CM-HP and CM-CV were less (P < 0.05) than in soybean meal. The AID and SID of crude protein in CM-HP was greater (P < 0.05) than in CM-CV. However, no differences were observed in AID and SID of any amino acids between CM-HP and CM-CV. The Concentration of standardized ileal digestible crude protein and almost all amino acids was greater (P < 0.05) in soybean meal than in CM-HP and CM-CV, and CM-HP contained more (P < 0.05) standardized ileal digestible crude protein and amino acids than CM-CV. In conclusion, increased Concentration of crude protein in canola meal does not compromise the Concentration of DE and ME, and does not compromise AID or SID of amino acids. As a consequence, the novel CM-HP supplies the same amount of DE and more digestible amino acids for growing pigs compared with CM-CV.

  • Energy Concentration and amino acid digestibility in high protein canola meal conventional canola meal and soybean meal fed to growing pigs
    Journal of Animal Science, 2015
    Co-Authors: J D Berrocoso, J Shoulders, J C Gonzalezvega, O J Rojas, H H Stein
    Abstract:

    : Two experiments were conducted to determine DE and ME and the standardized ileal digestibility (SID) of CP and AA in 2 sources of high-protein canola meal (CM-HP1 and CM-HP2), conventional canola meal (CM-CV), and soybean meal (SBM) fed to growing pigs. In Exp. 1, 40 barrows (51.5 ± 4.0 kg initial BW) were housed in metabolism cages and randomly allotted to 1 of 5 diets with 8 replicate pigs per diet. A corn-based diet (97.4% corn) and 4 diets that contained both corn and each of the 3 sources of canola meal or SBM were formulated. Feces and urine were collected for 5 d after a 5-d adaptation period. The DE and ME were 3,347 and 3,268 kcal/kg in corn, 3,312 and 2,893 kcal/kg in CM-HP1, 3,627 and 3,346 kcal/kg in CM-HP2, 2,798 and 2,492 kcal/kg in CM-CV, and 4,000 and 3,796 kcal/kg in SBM, respectively. Values for DE and ME were greater (P< 0.05) in SBM than in all other ingredients, but DE and ME were greater (P < 0.05) in corn and the 2 high-protein canola meals than in CM-CV. The DE and ME were also greater (P< 0.05) in CM-HP2 than in CM-HP1. In Exp. 2, 10 barrows (65.3 ± 10.4 kg initial BW) were equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 5 × 5 Latin square design with 5 diets and 5 periods in each square. A N-free diet and 4 corn starch-based diets that contained CM-HP1, CM-HP2, CM-CV, or SBM as the sole source of AA were formulated. Each period lasted 7 d and ileal digesta were collected on d 6 and 7 of each period. The SID of CP and all AA except Pro were greater (P < 0.05) in SBM than in the 3 sources of canola meal. With the exception of His and Lys, no differences in SID of indispensable AA were observed among the 3 sources of canola meal. The SID of His and Lys were greater (P < 0.05) in CM-HP1 and CM-HP2 than in CM-CV and the SID of CP was greater (P < 0.05) in CM-HP2 than in CM-CV, but no differences in the SID of indispensable AA were observed between CM-HP1 and CM-HP2. In conclusion, the 2 high-protein canola meals used in this experiment have ME values that are not different from corn but greater than in CM-CV. The SID of most AA is greater in SBM than in canola meals, but SID of His and Lys are greater in high-protein canola meals than in CM-CV. As a consequence, high-protein canola meals supply more ME and SID of AA for growing pigs than CM-CV.

  • Energy Concentration and phosphorus digestibility in yeast products produced from the ethanol industry and in brewers yeast fish meal and soybean meal fed to growing pigs
    Journal of Animal Science, 2014
    Co-Authors: Beob Gyun Kim, Yanhong Liu, H H Stein
    Abstract:

    Two experiments were conducted to determine the DE, ME, and standardized total tract digestibility (STTD) of P in 2 novel sources of yeast (C-yeast and S-yeast) and in brewers' yeast, fish meal, and soybean meal fed to growing pigs. The 2 new sources of yeast are coproducts from the dry-grind ethanol industry. The Concentrations of DM, GE, and P were 94.8%, 5,103 kcal/kg, and 1.07% in C-yeast; 94.4%, 4,926 kcal/kg, and 2.01% in S-yeast; 93.6%, 4,524 kcal/kg, and 1.40% in brewers' yeast; 91.4%, 4,461 kcal/kg, and 3.26% in fish meal; and 87.7%, 4,136 kcal/kg, and 0.70% in soybean meal, respectively. The DE and ME in each of the ingredients were determined using 42 growing barrows (28.9±2.18 kg BW). A corn-based basal diet and 5 diets containing corn and 24% to 40% of each test ingredient were formulated. The total collection method was used to collect feces and urine, and the difference procedure was used to calculate values for DE and ME in each ingredient. The Concentrations of DE in corn, C-yeast, S-yeast, brewers' yeast, fish meal, and soybean meal were 4,004, 4,344, 4,537, 4,290, 4,544, and 4,362 kcal/kg DM (SEM=57), respectively, and the ME values were 3,879, 3,952, 4,255, 3,771, 4,224, and 4,007 kcal/kg DM (SEM=76), respectively. The ME in S-yeast and fish meal were greater (P<0.05) than the ME in corn and brewers' yeast, whereas the ME in C-yeast and soybean meal were not different from those of any of the other ingredients. The STTD of P in the 5 ingredients was determined using 42 barrows (28.3±7.21 kg BW) that were placed in metabolism cages. Five diets were formulated to contain each test ingredient as the sole source of P, and a P-free diet was used to estimate the basal endogenous loss of P. Feces were collected for 5 d using the marker to marker method after a 5-d adaptation period. The STTD of P in brewers' yeast (85.2%) was greater (P<0.05) than the STTD of P in all the other ingredients except S-yeast (75.7%). The STTD of P in C-yeast (73.9%) was not different from the STTD of P in S-yeast and fish meal (67.3%) but was greater (P<0.05) than the STTD of P in soybean meal (56.7%). In conclusion, the 2 novel sources of yeast contain similar or greater Concentrations of Energy compared with brewers' yeast, corn, fish meal, and soybean meal, and the STTD of P in the 2 yeast products is not different from the STTD of P in fish meal.

  • Energy Concentration and phosphorus digestibility in canola cottonseed and sunflower products fed to growing pigs
    Canadian Journal of Animal Science, 2013
    Co-Authors: Diego A Rodriguez, J C Gonzalezvega, R C Sulabo, H H Stein
    Abstract:

    Rodriguez, D. A., Sulabo, R. C., Gonzalez-Vega, J. C. and Stein, H. H. 2013. Energy Concentration and phosphorus digestibility in canola, cottonseed, and sunflower products fed to growing pigs. Can. J. Anim. Sci. 93: 493–503. Many protein sources are available to the swine feed industry, but accurate data for the Energy Concentration and the standardized total tract digestibility (STTD) of P in these ingredients are lacking. Therefore, two experiments were conducted to determine the Concentration of digestible Energy (DE), metabolizable Energy (ME) and the STTD of P in oilseed products. In exp. 1, 48 barrows (44.8±3.9 kg) were fed a basal diet containing 97.15% corn or seven diets containing corn and canola seed (CS), canola meal (CM), cottonseed meal (CSM), sunflower seed (SFS), sunflower meal (SFM), de-hulled sunflower meal (SFM-DH), or soybean meal (SBM). Six pigs were allotted to each treatment. Sunflower seeds contained 5492 kcal kg−1, at least 689 kcal kg−1 more (P<0.05) ME than all other feed ingre...

  • phosphorus digestibility and Energy Concentration of enzyme treated and conventional soybean meal fed to weanling pigs
    Journal of Animal Science, 2011
    Co-Authors: K P Goebel, H H Stein
    Abstract:

    Two experiments were conducted to determine the apparent total tract digestibility (ATTD) of P and the Concentration of DE and ME in enzyme-treated soybean meal (SBM) and in conventional soybean meal (SBM-CV). Phosphorus digestibility in 2 enzyme-treated SBM (HP-310 and HP-340) and in SBM-CV was measured using 36 barrows (initial BW: 21.9 ± 1.1 kg) that were housed in metabolism cages and randomly allotted to 6 diets with 6 replicates per diet. During production, HP-310 had been treated with an enzyme mixture containing no phytase, whereas HP-340 was treated with an enzyme mixture that contained exogenous phytase. Three diets containing HP-310, HP-340, or SBM-CV as the sole source of P were formulated. Three additional diets also contained HP-310, HP-340, and SBM-CV, but each of these diets was fortified with 500 units of microbial phytase. The ATTD of P in HP-310 and SBM-CV increased (P 0.05; 83.8 and 87.7%, respectively). There were no differences (P > 0.05) in the ATTD of P between HP-310 and SBM-CV, but the ATTD of P in HP-340 was greater (P 0.05), but they were greater (P 0.05). It is concluded that enzyme treatment of SBM does not influence the digestibility of P or the Concentration of DE and ME in the meals.

  • growth performance and carcass quality of crossbreds pigs from two pietrain sire lines fed isoproteic diets varying in Energy Concentration
    Meat Science, 2016
    Co-Authors: L Camara, J D Berrocoso, J Coma, C J Lopezbote, G G Mateos
    Abstract:

    The effects of net Energy (NE) content of isoproteic diets on growth performance and carcass and meat quality traits were studied in crossbreds from Landrace×Large White females and two Pietrain sire lines (PIC L62 vs. German Pietrain). Feed intake (FI) decreased (Lineal, P<0.001) and feed efficiency improved (Lineal, P<0.001) as the NE content of the diet increased. Crossbreds from PIC L62 had greater (P<0.001) FI and average daily gain (ADG) but were less efficient (P<0.01) than crossbreds from German Pietrain. German Pietrain crossbreds were leaner (P<0.001) and had higher shoulder yield (P<0.01) and less fat at m. Gluteus medius (P<0.001) than carcasses from PIC L62 crossbreds. In summary, an increase in the NE Concentration of the diet improved feed efficiency but did not affect ADG. Crossbreeds from PIC L62 sires grew faster and had fatter carcasses than crossbreds from German Pietrain.

  • feed form and Energy Concentration of the diet affect growth performance and digestive tract traits of brown egg laying pullets from hatching to 17 weeks of age
    Poultry Science, 2015
    Co-Authors: B Saldana, L Camara, P Guzman, J Garcia, G G Mateos
    Abstract:

    : The influence of feed form and Energy Concentration of the diet on growth performance and the development of the gastrointestinal tract (GIT) was studied in brown-egg laying pullets. Diets formed a 2 x 5 factorial with 2 feed forms (mash vs. crumbles) and 5 levels of Energy differing in 50 kcal AMEn/kg. For the entire study (0 to 17 wk of age) feeding crumbles increased ADFI (52.9 vs. 49.7 g; P   0.05) by Energy content of the diet. At 5, 10, and 17 wk of age, the relative weight (RW, % BW) of the GIT and the gizzard, and gizzard digesta content were lower (P < 0.05 to P < 0.001) and gizzard pH was higher (P < 0.05 to P < 0.001) in pullets fed crumbles than in pullets fed mash. Energy Concentration of the diet did not affect any of the GIT variables studied. In summary, feeding crumbles improved pullet performance and reduced the RW of the GIT and gizzard, and increased gizzard pH at all ages. An increase in the Energy content of the diet improved FCR from 0 to 17 wk of age. The use of crumbles and the increase in the AMEn content of the diet might be used adventageously when the objetive is to increase the BW of the pullets. However, crumbles affected the development and weight of the organs of the GIT, which might have negative effects on feed intake and egg production at the beginning of the egg laying cycle.

  • productive performance of brown egg laying pullets from hatching to 5 weeks of age as affected by fiber inclusion feed form and Energy Concentration of the diet1
    Poultry Science, 2015
    Co-Authors: P Guzman, H A Mandalawi, A Perezbonilla, B Saldana, R Lazaro, G G Mateos
    Abstract:

    The effects of fiber inclusion, feed form, and Energy Concentration of the diet on the growth performance of pullets from hatching to 5 wk age were studied in 2 experiments. In Experiment 1, there was a control diet based on cereals and soybean meal, and 6 extra diets that included 2 or 4% of cereal straw, sugar beet pulp (SBP), or sunflower hulls (SFHs) at the expense (wt/wt) of the whole control diet. From hatching to 5 wk age fiber inclusion increased (P < 0.05) ADG and ADFI, and improved (P < 0.05) Energy efficiency (EnE; kcal AMEn/g ADG), but body weight (BW) uniformity was not affected. Pullets fed SFH tended to have higher ADG than pullets fed SBP (P = 0.072) with pullets fed straw being intermediate. The feed conversion ratio (FCR) was better (P < 0.05) with 2% than with 4% fiber inclusion. In Experiment 2, 10 diets were arranged as a 2×5 factorial with 2 feed forms (mash vs. crumbles) and 5 levels of AMEn (2,850, 2,900, 2,950, 3,000, and 3,050 kcal/kg). Pullets fed crumbles were heavier and had better FCR than pullets fed mash (P < 0.001). An increase in the Energy content of the crumble diets reduced ADFI and improved FCR linearly, but no effects were detected with the mash diets (P < 0.01 and P < 0.05 for the interactions). Feeding crumbles tended to improve BW uniformity at 5 wk age (P = 0.077) but no effects were detected with increases in Energy Concentration of the diet. In summary, the inclusion of moderate amounts of fiber in the diet improves pullet performance from hatching to 5 wk age. The response of pullets to increases in Energy content of the diet depends on feed form with a decrease in feed intake when fed crumbles but no changes when fed mash. Feeding crumbles might be preferred to feeding mash in pullets from hatching to 5 wk age.

    Poultry Science, 2012
    Co-Authors: A Perezbonilla, J Garcia, S Novoa, M Mohitiasli, M Frikha, G G Mateos
    Abstract:

    Abstract The influence of AMEn Concentration of the diet on productive performance and egg quality traits was studied in Hy-Line brown egg-laying hens differing in initial BW from 24 to 59 wk of age. Eight treatments were arranged factorially with 4 diets varying in Energy content (2,650, 2,750, 2,850, and 2,950 kcal of AMEn/kg) and 2 initial BW of the hens (1,733 vs. 1,606 g). Each treatment was replicated 5 times (13 hens per replicate), and all diets had similar nutrient content per unit of Energy. No interactions between Energy content of the diet and initial BW of the hens were detected for any trait. An increase in Energy Concentration of the diet increased (linear, P

  • Energy Concentration and amino acid digestibility in high protein canola meal conventional canola meal and in soybean meal fed to growing pigs
    Animal Feed Science and Technology, 2016
    Co-Authors: N W Jaworski, O J Rojas, H H Stein
    Abstract:

    Two experiments were conducted to determine digestible Energy (DE) and metabolizable Energy (ME) and the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein and amino acids in high protein canola meal (CM-HP), conventional canola meal (CM-CV), and soybean meal fed to growing pigs. In Exp. 1, 32 barrows (initial body weight: 47.3 ± 6.2 kg) were housed in metabolism cages and randomly allotted to one of four diets with eight replicate pigs per diet. A corn-based diet (973 g/kg corn) and three diets that contained both corn and each of the two sources of canola meal or soybean meal were formulated. Feces and urine were collected for 5 days after a 5-day adaptation period. The DE and ME values were 14.40 and 13.84 MJ/kg in corn, 12.43 and 10.34 MJ/kg in CM-HP, 11.02 and 9.65 MJ/kg in CM-CV, and 15.63 and 14.13 MJ/kg in soybean meal, respectively. The DE and ME were greater (P < 0.05) in corn and soybean meal than in CM-HP and CM-CV, but the DE and ME were not different between CM-HP and CM-CV. In Exp. 2, eight barrows (initial body weight: 46.4 ± 5.6 kg) were equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 4 × 4 Latin square design with 4 diets and 4 periods in each square. A N-free diet and three cornstarch based diets that contained CM-HP, CM-CV, or soybean meal as the sole source of amino acids were formulated. Each period lasted 7 days and ileal digesta were collected on day 6 and 7 of each period. The AID and SID of crude protein and most amino acids in CM-HP and CM-CV were less (P < 0.05) than in soybean meal. The AID and SID of crude protein in CM-HP was greater (P < 0.05) than in CM-CV. However, no differences were observed in AID and SID of any amino acids between CM-HP and CM-CV. The Concentration of standardized ileal digestible crude protein and almost all amino acids was greater (P < 0.05) in soybean meal than in CM-HP and CM-CV, and CM-HP contained more (P < 0.05) standardized ileal digestible crude protein and amino acids than CM-CV. In conclusion, increased Concentration of crude protein in canola meal does not compromise the Concentration of DE and ME, and does not compromise AID or SID of amino acids. As a consequence, the novel CM-HP supplies the same amount of DE and more digestible amino acids for growing pigs compared with CM-CV.

    Abstract:

    : Two experiments were conducted to determine DE and ME and the standardized ileal digestibility (SID) of CP and AA in 2 sources of high-protein canola meal (CM-HP1 and CM-HP2), conventional canola meal (CM-CV), and soybean meal (SBM) fed to growing pigs. In Exp. 1, 40 barrows (51.5 ± 4.0 kg initial BW) were housed in metabolism cages and randomly allotted to 1 of 5 diets with 8 replicate pigs per diet. A corn-based diet (97.4% corn) and 4 diets that contained both corn and each of the 3 sources of canola meal or SBM were formulated. Feces and urine were collected for 5 d after a 5-d adaptation period. The DE and ME were 3,347 and 3,268 kcal/kg in corn, 3,312 and 2,893 kcal/kg in CM-HP1, 3,627 and 3,346 kcal/kg in CM-HP2, 2,798 and 2,492 kcal/kg in CM-CV, and 4,000 and 3,796 kcal/kg in SBM, respectively. Values for DE and ME were greater (P< 0.05) in SBM than in all other ingredients, but DE and ME were greater (P < 0.05) in corn and the 2 high-protein canola meals than in CM-CV. The DE and ME were also greater (P< 0.05) in CM-HP2 than in CM-HP1. In Exp. 2, 10 barrows (65.3 ± 10.4 kg initial BW) were equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 5 × 5 Latin square design with 5 diets and 5 periods in each square. A N-free diet and 4 corn starch-based diets that contained CM-HP1, CM-HP2, CM-CV, or SBM as the sole source of AA were formulated. Each period lasted 7 d and ileal digesta were collected on d 6 and 7 of each period. The SID of CP and all AA except Pro were greater (P < 0.05) in SBM than in the 3 sources of canola meal. With the exception of His and Lys, no differences in SID of indispensable AA were observed among the 3 sources of canola meal. The SID of His and Lys were greater (P < 0.05) in CM-HP1 and CM-HP2 than in CM-CV and the SID of CP was greater (P < 0.05) in CM-HP2 than in CM-CV, but no differences in the SID of indispensable AA were observed between CM-HP1 and CM-HP2. In conclusion, the 2 high-protein canola meals used in this experiment have ME values that are not different from corn but greater than in CM-CV. The SID of most AA is greater in SBM than in canola meals, but SID of His and Lys are greater in high-protein canola meals than in CM-CV. As a consequence, high-protein canola meals supply more ME and SID of AA for growing pigs than CM-CV.

  • growth performance and carcass quality of crossbreds pigs from two pietrain sire lines fed isoproteic diets varying in Energy Concentration
    Meat Science, 2016
    Co-Authors: L Camara, J D Berrocoso, J Coma, C J Lopezbote, G G Mateos
    Abstract:

    The effects of net Energy (NE) content of isoproteic diets on growth performance and carcass and meat quality traits were studied in crossbreds from Landrace×Large White females and two Pietrain sire lines (PIC L62 vs. German Pietrain). Feed intake (FI) decreased (Lineal, P<0.001) and feed efficiency improved (Lineal, P<0.001) as the NE content of the diet increased. Crossbreds from PIC L62 had greater (P<0.001) FI and average daily gain (ADG) but were less efficient (P<0.01) than crossbreds from German Pietrain. German Pietrain crossbreds were leaner (P<0.001) and had higher shoulder yield (P<0.01) and less fat at m. Gluteus medius (P<0.001) than carcasses from PIC L62 crossbreds. In summary, an increase in the NE Concentration of the diet improved feed efficiency but did not affect ADG. Crossbreeds from PIC L62 sires grew faster and had fatter carcasses than crossbreds from German Pietrain.

The SID of most AA is greater in SBM than in canola meals, but SID of His and Lys are greater in high-protein canola meals than in CM-CV. As a consequence, high-protein canola meals supply more ME and SID of AA for growing pigs than CM-CV.

The DE and ME values were 14.40 and 13.84 MJ/kg in corn, 12.43 and 10.34 MJ/kg in CM-HP, 11.02 and 9.65 MJ/kg in CM-CV, and 15.63 and 14.13 MJ/kg in soybean meal, respectively. The DE and ME were greater (P < 0.05) in corn and soybean meal than in CM-HP and CM-CV, but the DE and ME were not different between CM-HP and CM-CV. In Exp. 2, eight barrows (initial body weight: 46.4 ± 5.6 kg) were equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 4 × 4 Latin square design with 4 diets and 4 periods in each square. A N-free diet and three cornstarch based diets that contained CM-HP, CM-CV, or soybean meal as the sole source of amino acids were formulated. Each period lasted 7 days and ileal digesta were collected on day 6 and 7 of each period. The AID and SID of crude protein and most amino acids in CM-HP and CM-CV were less (P < 0.05) than in soybean meal. The AID and SID of crude protein in CM-HP was greater (P < 0.05) than in CM-CV. However, no differences were observed in AID and SID of any amino acids between CM-HP and CM-CV. The Concentration of standardized ileal digestible crude protein and almost all amino acids was greater (P < 0.05) in soybean meal than in CM-HP and CM-CV, and CM-HP contained more (P < 0.05) standardized ileal digestible crude protein and amino acids than CM-CV. In conclusion, increased Concentration of crude protein in canola meal does not compromise the Concentration of DE and ME, and does not compromise AID or SID of amino acids. As a consequence, the novel CM-HP supplies the same amount of DE and more digestible amino acids for growing pigs compared with CM-CV.
