“…No significant difference was observed in T4 in CM levels, which may be due to the physiological equilibrium in the thyroid gland of chicks after the 6 th wk of age. In agreement with this result, Taraz et al (2006) reported no difference in T4 from using rapeseed meal in broiler diet. Note.…”

Canola meal (CM) is commonly used in poultry diets; however, its use is limited due to anti-nutritive factors. Therefore, this study was conducted to evaluate the effects of feeding various levels of canola meal (CM) with or without multi-enzyme supplement on broiler chickens. Four levels of CM (0, 5, 10 and 20%) were used with or without multi-enzyme (0 or 300 g/ton of diet) in a factorial design 4 × 2 in 8 dietary combinations. During the experimental period (0-42 d of age), inclusion of CM at a level of 5 and 10% without multi-enzyme and at a level of 20% with or without multi-enzyme decreased body weight gain and gain:feed ratio compared to control (CON; P < 0.05). However, there was no difference in the final body weight at day 42 of age between the groups. No differences were found in carcass characteristics between treatments. Inclusion of CM in broiler diet decreased serum antibody titer at 42 d of age compared to the control and enzyme-supplemented CM groups (P < 0.05). Inclusion of CM with multi-enzyme supplement decreased serum total cholesterol, total triglyceride and glutamate oxaloacetate transaminase compared to CON and enzyme-unsupplemented groups (P < 0.05). Diets supplemented with CM had higher serum creatinine than CON and enzyme-supplemented CM groups (P < 0.05). Lower serum triiodothyronine in broilers fed diet supplemented with 10 or 20% CM was noticed (P < 0.05). CM with multi-enzyme supplementation to broiler ration showed a slight increase in net revenue.

“…Inclusion of CM at a level of 10 and 20% in broiler diet reduced serum concentration of T3, in agreement with Taraz et al (2006). However, Ramesh et al (2006) observed that T3 and T4 levels were not influenced by the inclusion of rapeseed meal.…”

“…In this respect, Aljuobori et al (2016) suggested that glucosinolates in CM may destroy cellular T 3 receptors and thus increase the thyroid hormones level in blood. In contrary to our results, Taraz et al (2006); Mikulski et al (2012); Payvastegan et al (2017) indicated that an increasing of inclusion levels of CM was followed by plasma T 3 concentrations reduction. However, Taraz et al (2006); Payvastegan et al (2017) reported no significant differences in plasma T 4 among all experimental groups.…”

“…In contrary to our results, Taraz et al (2006); Mikulski et al (2012); Payvastegan et al (2017) indicated that an increasing of inclusion levels of CM was followed by plasma T 3 concentrations reduction. However, Taraz et al (2006); Payvastegan et al (2017) reported no significant differences in plasma T 4 among all experimental groups. They attributed these discrepancies to differences in glucosinolates content in CM, diet ingredients, composition of gut microorganism besides, the extent of glucosinolates degradation by heat during the oil extraction process (Woyengo et al, 2011).…”

“…Also, the present results are compatible with the results of Ashnie et al (2015) where, they did not found a significant differences of relative spleen weights among broilers fed diets contained 0, 7.5 and 15% CM while, the broilers fed diets contained 22.5 and 30% CM showed a significant increase of relative weights of spleen compared to the control group which was contrary with our results. In this respect, Taraz et al (2006) reached to 38.2, 28.95 and 23.16% CM as maximum levels in starter, grower and finisher diets, respectively; they reported no significant differences in relative spleen weights between all CM groups and the CM free group; that showed disagreement with the present results of broilers fed 90% CM replacement of SBM compared to control, as the starter, grower and finisher diets contained 32.63, 27.67 and 29.89% CM, respectively. In the same vein, An et al (2016) reported no significant differences among relative spleen weights of broilers fed wheat-SBM based diets contained 0, 3, 5, 10 and 15% CM.…”

This study was conducted to evaluate the effects of replacing soybean meal (SBM) protein with canola meal (CM) protein on productive performance, nutrient digestibility, immune response, lymphoid organs, blood parameters, carcass fatty acids and cecum microbiota of broilers. A total of 160 one d-old Arbor Acres broiler chicks were randomly allocated to 4 dietary treatments of 5 replicates, where, CM protein replaced SBM protein at 0, 30, 60, and 90% for a 39 days feeding trial. The results showed no significant differences in productive performance parameters among control, 30% and 60% treatment groups, while, at 90% replacement level, all values decreased (P < 0.0001) all over the experimental period. The 90% replacement group showed depression of crude protein (P < 0.001) and crude fiber (P < 0.001) digestibility and spleen relative weight (P = 0.0386) with increase of thymus (P = 0.0555), bursa (P = 0.0334) and thyroid relative weight (P = 0.0276) as well as thyroid hormones (P = 0.0034, 0339) for T3, T4, respectively, while, there were no significant differences among control, 30% and 60% treatment groups for those criteria. However, CM levels had no effect on serum haemagglutination inhibition (HI) titer against Newcastle disease. CM significantly decreased serum cholesterol content (P = 0.0002) while increased HDL (P = 0.0532), compared to the control. CM levels showed an increase in carcass meat content of unsaturated fatty acids content (P < 0.0001) as the replacement level gradually increased. Erucic acid did not detected in carcass. All CM levels decreased cecum content of E. coli (P = 0.0051) while increased that of Lactobacillus (P = 4094). Conclusively, CM can be used safely in broiler diet to replace up to 60% of SBM protein without negative effects on growth and immune response of broilers.

BACKGROUNDWe investigated the impact of using canola meal (CM) or corn distillers dried grain soluble (cDDGS) in place of soybean meal (SBM) in low‐crude‐protein diets supplemented with amino acids (AA) on AA digestibility, gut morphometrics, and AA transporter genes in broiler chicken. On day 0, 540 Cobb 500 male broilers were allocated to six diets in 36‐floor pens. The positive control (PC) was a corn‐SBM diet with adequate crude protein (CP). The CP level of negative control (NC) was decreased by 45 and 40 g kg−1 relative to PC for grower and finisher phases, respectively. The subsequent two diets had the same CP levels as NC but with cDDGS added at 50 or 125 g kg−1. The last two diets had the same CP as NC but with CM added at 50 or 100 g kg−1.RESULTSDietary CP reduction in corn‐SBM diets increased (P < 0.05) the digestibility of Lys (88.5%), Met (90.7%), Thr (77.4%), Cys (80.7%), and Gly (84.7%). Increasing levels of cDDGS linearly decreased (P < 0.05) the digestibility of Asp, Cys, Glu, and Ser, whereas increasing CM level linearly decreased (P < 0.05) the digestibility of Cys, Pro, and Ser. The CP reduction in corn‐SBM diets produced downward expression of peptide transporter1 and decreased (P < 0.05) absolute pancreas and ileum weight and length of jejunum and ileum.CONCLUSIONSPartial replacement of SBM with alternative protein feedstuffs (cDDGS or CM) in low‐CP diets had minimal effects on AA digestibility and mRNA levels of peptides and AA transporters. © 2024 The Authors.
