Fish & Shellfish Immunology, 2018Co-Authors: Serge Dossou, Saichiro Yokoyama, Mahmoud A O Dawood, Mohammed El F Basuini, Adissin Olivier, Shunsuke Koshio, Manabu Ishikawa, Amr I ZaineldinAbstract:This study evaluated the effects of dietary substitution of fishMeal by graded levels of a blend composed of Aspergillus oryzae fermented Rapeseed Meal [0% (RM0), 25% (RM25), 50% (RM50), 75% (RM75) and 100% (RM100)] on growth performance, haemato-immunological responses and antioxidative status of Pagrus major (average weight 5.5 ± 0.02 g). After 56 days, growth performances were significantly improved in fish fed RM25 diet compared to control (P < 0.05). Meanwhile, up to 50% replacement of fishMeal did not affect growth performance, feed conversion efficiency, protein efficiency ratio, protein apparent digestibility, protease activity, fish somatic indices and survival compared to control. While blood hematocrit and plasma protein were significantly enhanced in groups fed RM0 and RM25 diets, most of the hematological parameters did not change through the trial except glutamic pyruvate transaminase which was significantly increased in RM75 and RM100 groups and blood cholesterol which was gradually decreased with the increasing level of the blend. Interestingly, feeding fish with RM25 and RM50 diets significantly showed enhanced lysozyme, bactericidal and peroxidase activities and fish fed the same diets showed high resistance against oxidative stress (biological antioxidant potential and reactive oxygen metabolites). Additionally, catalase activity and tolerance against low salinity seawater were higher in fish fed RM25 diet. These findings suggested that, at a moderate level (25% and 50%), substitution of fishMeal by the fermented Rapeseed Meal promoted growth, nutrient utilization, and exerted immune responses and anti-oxidative effects in red sea bream.

effect of partial replacement of fish Meal by fermented Rapeseed Meal on growth immune response and oxidative condition of red sea bream juvenile pagrus major
Aquaculture, 2018Co-Authors: Serge Dossou, Saichiro Yokoyama, Mahmoud A O Dawood, Mohammed El F Basuini, Shunsuke Koshio, Manabu Ishikawa, Abdelaziz Mohammed Elhais, Adissin OlivierAbstract:Abstract A 65-day feeding trial was conducted to investigate the effects of replacing fish Meal with yeast fermented Rapeseed Meal (FRM) on growth performance, feed utilization, innate immune responses and oxidative stress of red sea bream juvenile, Pagrus major. Triplicate groups of fish received five isonitrogenous and isocaloric diets where fish Meal was replaced with FRM at 0% (FRM0), 18.75% (FRM1), 37.5% (FRM2), 56.25% (FRM3) and 75% (FRM4), respectively. The results indicated that there were no differences in final body weight, weight gain, specific growth rate and feed intake among all groups when compared to fish fed the control diet (FRM0) except for those fed the FRM4 diet, which showed reductions (P 0.05) on whole body ash, lipid contents, body somatic indices or gut protease activity. Highest levels of fermented Rapeseed Meal (FRM3 and FRM4 diets) significantly decreased (P

apparent and standardized total tract digestibility by growing pigs of phosphorus in canola Meal from north america and 00 Rapeseed Meal and 00 Rapeseed expellers from europe without and with microbial phytase
Journal of Animal Science, 2015Co-Authors: Tanawong Maison, H H SteinAbstract:: An experiment was conducted to determine apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) by growing pigs of P in canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers. Canola Meal and 00-Rapeseed Meal are the coproducts produced after the residual oil has been solvent extracted from the prepressed canola seeds and 00-Rapeseeds, respectively, whereas 00-rapeseeed expellers is the coproduct from 00-Rapeseeds that have been only expeller pressed. Two hundred sixteen barrows (18.0 ± 1.5 kg initial BW) were allotted to 36 diets and 6 replicate pigs per diet. Five samples of canola Meal from solvent-extraction crushing plants in North America, 8 samples of 00-Rapeseed Meal from solvent-extraction crushing plants in Europe, and 5 samples of 00-Rapeseed expellers from mechanical-press crushing plants in Europe were used in the experiment. Eighteen diets were prepared by including 40% of each source of canola Meal, 00-Rapeseed Meal, or 00-Rapeseed expellers in 1 diet. Eighteen additional diets were formulated by adding 1,500 units of microbial phytase to the diets. The only source of P in the diets was canola Meal, 00-Rapeseed Meal, or 00-Rapeseed expellers. Pigs were placed in metabolism crates that allowed for total fecal collection. Pigs were fed at 2.5 times their estimated energy requirement for maintenance. Ingredients, diets, and feces were analyzed for P, and the ATTD and STTD of each source of canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers were calculated. A value for endogenous P loss of 190 mg/kg DMI was used to calculate the STTD of P. Results indicated that the ATTD and STTD of P for canola Meal were not different from values obtained in 00-Rapeseed Meal, and the ATTD and STTD of P in 00-Rapeseed Meal were not different from values for 00-Rapeseed expellers. The ATTD and STTD of P increased (P < 0.001) from 44.99 and 48.82% to 64.08 and 67.97% for canola Meal, from 46.77 and 50.36% to 63.53 and 67.29% for 00-Rapeseed Meal, and from 44.83 and 48.60% to 69.18 and 72.99%, respectively, for 00-Rapeseed expellers by adding microbial phytase to the diets. In conclusion, although the concentration of ether extract is much greater in 00-Rapeseed expellers than in 00-Rapeseed Meal and canola Meal, the ATTD and STTD of P for these ingredients are not different, and addition of microbial phytase results in improved digestibility of P in canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers.

digestibility of energy and detergent fiber and digestible and metabolizable energy values in canola Meal 00 Rapeseed Meal and 00 Rapeseed expellers fed to growing pigs
Journal of Animal Science, 2015Co-Authors: Tanawong Maison, H H SteinAbstract:: There are limited data on the DE and ME values and the digestibility of fiber in canola Meal, Rapeseed Meal, and Rapeseed expellers fed to pigs. This experiment was conducted to measure the apparent total tract digestibility (ATTD) of energy, ADF, and NDF and to calculate DE and ME values in canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers fed to growing pigs. Twenty-three barrows (initial BW: 27.7 ± 2.92 kg) were allotted to an 8 × 23 Youden square design with 8 periods and 23 animals. Twenty-three diets were prepared: a corn basal diet and 22 diets based on corn and 1 of 22 test ingredients. The test ingredients were 6 canola Meals from solvent-extraction crushing plants in North America, eleven 00-Rapeseed Meals from solvent-extraction crushing plants in Europe, and five 00-Rapeseed expellers from mechanical-press crushing plants in Europe. Pigs were placed in metabolism cages that allowed for the total, but separate, collection of feces and urine. The DE and ME values were calculated for each source of canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers using the difference procedure. The ATTD of GE and the DE and ME values in canola Meal were not different from the values in 00-Rapeseed Meal, but 00-Rapeseed expellers had greater ( < 0.01) ATTD of GE and DE and ME values than 00-Rapeseed Meal. Average DE and ME values were 3,378 and 3,127 kcal/kg DM in canola Meal, 3,461 and 3,168 kcal/kg DM in 00-Rapeseed, and 4,005 and 3,691 kcal/kg DM in 00-Rapeseed expellers. The ATTD of ADF was 12.3% greater ( < 0.01) in 00-Rapeseed Meal than in canola Meal, but no differences were observed in ATTD of NDF between canola Meal and 00-Rapeseed Meal. No differences were observed in ATTD of ADF and NDF between 00-Rapeseed Meal and 00-Rapeseed expellers. The models for predicting the DE and ME values of canola and Rapeseed products were DE = -1,583 + 6.64 × ash + 7.01 × ADF - 33.17 × NDF + 98.66 × ADL + 1.07 × GE ( = 0.94) and ME = -630.8 + 14.13 × ash + 5.02 × crude fiber + 3.45 × ADF + 1.03 × DE ( = 0.98). In conclusion, the digestibility of energy and NDF and the DE and ME values are not different between canola Meal and 00-Rapeseed Meal. However, 00-Rapeseed expellers have greater energy digestibility and contain 7.6% more DE and 7.7% more ME than 00-Rapeseed Meal.

digestibility by growing pigs of amino acids in canola Meal from north america and 00 Rapeseed Meal and 00 Rapeseed expellers from europe
Journal of Animal Science, 2014Co-Authors: Tanawong Maison, H H SteinAbstract:: The digestibility of CP and AA by growing pigs in coproducts from canola and 00-Rapeseed may be influenced by the variety of seeds that was grown and the processing method used to extract the oil from the seeds. Therefore, the objective of this experiment was to determine the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of CP and AA in canola Meal, 00-Rapeseed Meal, and 00-Rapeseed expellers fed to growing pigs. Canola Meal and 00-Rapeseed Meal are the coproducts produced after the residual oil has been solvent extracted from canola seeds and 00-Rapeseeds, respectively, whereas 00-Rapeseed expellers is the coproduct from 00-Rapeseeds that have been only expeller pressed. Twenty-three barrows (initial BW: 28.8 ± 2.64 kg) that had a T-cannula installed in the distal ileum were allotted to a 9 × 23 Youden square design with 9 periods and 23 dietary treatments. The 23 diets included 7 diets based on the 7 samples of canola Meal, 10 diets based on the 10 samples of 00-Rapeseed Meal, 5 diets based on the 5 samples of 00-Rapeseed expellers, and a N-free diet. Each source of canola or Rapeseed coproducts was used as the only source of CP and AA in 1 diet. The SID of CP and all AA except Val, Cys, and Glu were not different between canola Meal and 00-Rapeseed Meal, but 00-Rapeseed expellers had greater (P < 0.01) SID of CP and all AA except Thr, Trp, and Gly than 00-Rapeseed Meal, which possibly is due to heat damage in 00-Rapeseed Meal. For Lys, Met, Thr, and Trp, SID values of 70.6%, 84.5%, 73.0%, and 82.6%, and 71.9%, 84.6%, 72.6%, and 82.6% were obtained in canola Meal and Rapeseed Meal, respectively, whereas values in 00-Rapeseed expellers were 74.7%, 87.1%, 74.0%, and 83.4%. The SID for most AA was different (P < 0.05) among the 7 sources of canola Meal, among the 10 sources of 00-Rapeseed Meal, and among the 5 sources of 00-Rapeseed expellers. The concentration of standardized ileal digestible indispensable AA in canola and 00-Rapeseed coproducts can be predicted from the concentration of the corresponding AA with only a low to moderate correlation (r(2) = 0.206 to 0.655). In conclusion, AA digestibility is not different between canola Meal and 00-Rapeseed Meal, but 00-Rapeseed expellers have greater digestibility of most AA than 00-Rapeseed Meal. Prediction equations may not always adequately estimate the concentration of indispensable AA and standardized ileal digestible indispensable AA in canola and 00-Rapeseed coproducts.
