“…The use of large amounts of RSM is limited because of the lower energy and higher fi bre contents compared with SBM. The crude fi bre content of RSM negatively affected the AMEn value for broiler chickens (Chibowska et al, 2000). These fi ndings are in agreement with those showing that the inclusion of high levels of CM in broiler diets have adverse effects on broiler chickens performance (Tripathi and Mishra, 2007).…”

Three hundred and eighty-four day-old Ross broiler chicks were used in a completely randomized experimental design with 4×2 factorial arrangements using four rapeseed meal (RSM) levels with and without a multi-enzyme preparation. RSM levels included: A: control (without RSM); B: 5, 10 and 15%; C: 10, 15 and 20%; D: 15, 20 and 25% RSM in starter, grower and fi nisher periods, respectively. Body weight gain and feed conversion ratio in treatments B and C were similar to controls, but in treatment D, weight gain decreased and FCR increased (P<0.05). Feed intake of broilers was not affected by different levels of RSM (P>0.05). Enzyme supplementation had no signifi cant effect (P>0.05) on growth performance but resulted in a signifi cant increase in ileal digestibility of protein (P<0.05). Feeding high levels of RSM (Treatment D) signifi cantly increased liver and gizzard weights and decreased abdominal fat (P<0.05).

“…One of the reasons for reduced broilers BW gain between 1 to 21 d may be due to a higher crude fiber content of diets that containing 20% CM, which may be negatively affected AME n value for broiler chickens (Chibowska et al, 2000). Another of the reasons for reduced broilers BW gain between 1 to 21 d probably due to higher NSP content of CM as compared with SBM.…”

Growth Performance, Organ Weights and, Blood Parameters of Broilers Fed Diets Containing Graded Levels of Dietary Canola Meal and Supplemental Copper

An experiment with 495 one-day-old male broiler chicks was conducted to investigate the effects of different dietary levels of canola meal (0, 10, 20%) and copper (0, 125, 250 mg/kg) on performance, carcass characteristics and some blood parameters. A completely randomized design with 3×3 factorial arrangement was used with 5 replicates from 1 to 42 of age. Feed intake was not significantly affected by treatments during 1 to 21 d, 21 to 42 d and throughout the study (P＞0.05). The body weight gain and feed conversion ratio was significantly impaired (P＜ 0.05) when 20% canola meal was added in the diets between 1 to 21 d. Addition of copper significantly improved body weight gain (P＜0.01) and feed conversion ratio (P＜0.05) of the birds during the 21 to 42 d and throughout the study. Carcass yield significantly (P＜0.05) increased due to addition of 250 mg/kg of copper. Proportion of thyroid glands (P＜0.0001), breast, liver, gizzard, pancreas and cecal significantly (P＜0.05) were affected by 20% canola meal. Plasma alkaline phosphatase and blood glutathione peroxidase activities were unaffected (P＞0.05) by dietary treatments. An added level of 20% canola meal was significantly reduced plasma zinc concentration. Levels of copper supplementation increased (P＜0.001) plasma copper and decreased (P＜0.05) plasma zinc levels. Plasma lipids altered by supplementation of copper, so that decreased plasma triglycerides (P＜0.01) and cholesterol (P＜ 0.05) concentrations and also increased high density lipoprotein (P＜0.05). In conclusion, the results of this study indicate that no effects of added canola meal up to 20% of the diet on the growth performance. In addition from this study it can conclude that supplementation with dietary copper had beneficial effects on growth performance and plasma biochemical characteristics of broiler chickens.

“…It can therefore be concluded that fractionation did not give the expected benefits. Chibowska et al (2000) found, moreover, that lowering the level of fibre and increasing the share of protein in rapeseed meal by mechanical separation is a costly and economically unjustified process. Rotkiewicz and Zadernowski (1997) believe that it would be more beneficial to remove the seed coat of rapeseed before oil is pressed.…”

“…The use of rapeseed meal in the nutrition of broilers is more common (Smulikowska et al, 1991(Smulikowska et al, , 1998Chibowska et al, 2000;Kamińska et al, 2000), than in laying hens (Rutkowski et al, 1989;Gwara et al, 1993;Brettschneider et al, 1995;Niemiec et al, 2001). This may be caused by the occurrence of the unpleasant "fishy" odour of eggs from some hens fed rapeseed meal.…”

One hundred and seventy-five laying hens each of lines Hy-Line and ISA Brown were divided into seven groups of 25 birds and maintained in individual cages from the age of 26 weeks for 9 months of laying. The hens were fed isoprotein and isocaloric diets containing 16.7% crude protein and 11.4 MJ/kg. In the experimental diets, 45, 60 or 100% of the protein of soyabean meal was replaced by protein from regular rapeseed meal (R-RSM) or fractionated rapeseed meal (S-RSM) containing 11% more protein and 14% less crude fibre. Every 8 weeks egg and egg shell quality were assessed on 15 eggs per group; twice during the experiment egg odour was assessed on eggs from all of the hens. The use of rapeseed meal, both R-RSM and S-RSM, had no effect on laying rate parameters of egg and egg shell quality. As the content of rapeseed meal in the diet increased, the weight of eggs decreased (P<0.01). Among the hens fed the ration containing rapeseed meal, 3.4% of the Hy-Line and 7.4% of the ISA Brown hens laid eggs with a fishy odour. The type of rapeseed meal and its content in the diets had no effect on the occurrence or intensity of the non-specific odour of eggs.
