An experiment was designed to investigate the possibility of using rapeseed meal as a source of protein in dietary Arian broiler chickens. Five diets were tested in a completely randomized design. Rapeseed meal was tested to replace soybean meal with the levels of 0 (control), 25, 50, 75 and 100 percent during the starter and grower periods. Feed intake during the grower period was lower in the 100% replacement (P<0.05). Body weight gain was also lower in the 100% replacement during the starter, grower and total feeding periods and was statistically different (P<0.05) from other treatments, while there was no significant difference among control and 25% replacement. Different levels of rapeseed meal in the diets also affected the feed conversion ratio (FCR). The FCR in the 100% replacement for the starter, grower and total feeding periods were statistically different (P<0.05) from that of the control and 25% replacement but no difference was found between control and 25% replacement. Chemical analysis of the rapeseed meal showed that the amount of progoitrin, gluconapin, napoleiferin and glucobrassicanapin were 44.2, 16.8, 10.5 and 7.5 µmol/g DM, respectively. These findings indicated that the aliphatic glucosinolates content of the meal is rather high, as compared to the accepted limit of 30 µmol/g DM of aliphatic glucosinolates in the canola meal. It can be concluded that 25% of soybean meal in the diet of Arian broiler chickens can be replaced with rapeseed meal as a source of protein.

An experiment was conducted in order to study the effect of replacing soybean meal with rapeseed meal on performance, organs weight, blood biochemical parameters, methabolisable energy, and glucosinolates and erucic acid rate as a completely randomized design with 6 dietary treatments, 4 replicates with 15 birds in each replication. Three hundred and sixty one-day-old female Cobb hybrid broiler chicks were used. Methabolisable energy, glucosinolates and erucic acid content of meal were determined. rapeseed meal was replaced instead of soybean one with the levels of 0 (control), 20, 40, 60, 80 and 100 percent. In all of the diets, 0.05 percent multi enzyme (Kemin®) was used. Feed intake, body weight gain and feed conversion ratio were determined at the days 0-21, 21-49 and in the whole period. Morever the values of relative weight of liver, pancreas, ingluvies, gizzard, serum concentrations of triiodothronine and thyroxine were determined at 49 days of age. Sas software and Duncan’s test was used for analysis of variance and comporison of means, respectively. Chemical analysis of meal showed that the amount of the aliphatic glucosinolate and erucic acid of rapeseed were higher than the amount of that in canola meal. The feed conversion ratio of 60, 80 and 100 percent replacement were statistically different (P<0.01) from the control, 20 and 40 percent treatments. The results of statistical analysis indicated that there was no significant effect of rapeseed meal levels on relative weight of gizzard, ingluvies and pancreas, but significant effect on relative weight of heart and liver in 80 and 100 percent treatments was sean (P<0.05). The lowest blood serum concentration of triiodithyronine and thyroxine hormone in chicks were observed at 80 and 100 percent trearments (P<0.01). The results also showed that 40% of soybean meal can be replaced with rapeseed one in the broiler chick diets, but improving of meal quality is necessary for higher levels of replacement.

Objective: To study the effects of rapeseed meal and iodine supplementation on performance, organs weight and some biochemical parameters of broiler chicks.Design: Completely randomized design with 3 dietary treatments.Animals: One hundred and twenty one-day-old Arian broiler chicks (mixed male and female).Procedure: Chickens were categorized into 3 groups:soybean meal, rapeseed meal, and rape seed meal plus iodine (2mg/kg) .Feed intake, body weight gain and feed conversion ratio were determined at the end of starter, grower, finisher and whole period. states Moreover, the values of relative weight of liver, gallbladder, heart, spleen, gizzard, abdominal fat pad and carcass accompaning with serum concentrations of triiodothyronine, thyroxine, gamma glutamyltransferase and alanin aminotransferase were determined at 49 day of age.Statistical analysis: Significant differences among treatments determined by Duncan's multiple range tests. Results: While rapeseed meal (RSM) reduced, body weight gain and feed conversion ratio, iodine supplement did not affect body weight gain and feed conversion ratio during starter, grower and whole period states. In contrast to iodine treatment the highest weight of gallbladder and its ratio to whole body weight were seen with RSM. The weight of abdominal fat pad and its ratio to whole body weight were reduced in RSM and RSM puls iodine supplementation. Iodine Supplementation had effect on the concentration of thyroxine, triiodothyronine gamma glutamyltransferase and alanin aminotransferase in RSM group.Conclusion: The complete replacement of rapeseed meal with soybean reduced performance and concentration of triiodothyronine hormone, and increased some organs weight. idoine supplementation had no effect on erfrmanc.

In this research, effect of treating native rapeseed meal (NRSM) with microwave irradiation on chemical composition, glucosinolate, phytic acid, ruminal dry matter (DM) and crude protein (CP) degradability, metabolizable protein (MP) and in vitro CP digestibility of before and after irradiation were investigated. At first, moisture content of samples (three sample of 500 g) were increased to 250 g/kg. Then, were subjected to microwave irradiation at a power of 800 W for 2, 4 or 6 min. Chemical composition, phytic acid and glucosinolate contents of untreated and irradiated samples were determined by standard methods. Degradation kinetics of CP were determined according to in situ procedure. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was used to monitor protein subfractions and the fate of true proteins of untreated and irradiated feed samples in the rumen. The results of experience showed that irradiation decreased the total glucosinolate and phytic acid content of NRSM (p < 0. 001). Ruminal disappearance of DM and CP in different incubation times linearly increased (p < 0. 05) as irradiation time increased. Based on results of this study, microwave irradiation more than 2 min decreased glucosinolate and phytic acid content and ruminal degradability of CP and increased by pass protein, in vitro CP digestibility and MP of NRSM and eventually, microwave irradiation was effective in improving nutritional value of NRSM for using in ruminant diet.

This study investigated the effects of using rapeseed meal instead of soybean meal on meat quality, morphology, and ileum microbial population in Japanese quail using 675 Japanese quail in a completely randomized design with 9 treatments, 5 repetitions, and 15 quail per repetition. The treatments consisted of a control group fed with a corn and soybean meal-based diet without additives, as well as rapeseed meal replacing soybean meal at 25, 50, 75, and 100 percent both with and without protoxin probiotic (200 mg/kg) supplementation diets from 7 to 35 days of ages. Treatments without probiotics had no effect on quail meat pH and percentage of loss due to cooking and the rapeseed meal without probiotic had no effect on meat quality of quail (P>0.05). The treatment fed with the control treatment and the 25% rapeseed meal treatment with probiotics had the highest percentage of water retention capacity, lover loss due to cooking and higher amount of lactobacillus counted(P<0.05). The control treatments and 25% rapeseed meal had lover amount of malondialdehyde and 25, 50 % rapeseed meal treatments with probiotic had lover Escherichia coli count (P<0.05). Also 25% rapeseed meal with probiotic treatment increase villi height and decerse crypt depth compare with other treatments(P<0.05). In conclusion, this study suggests that inclusion of 25 % rapeseed meal instead of soybean meal with probiotic supplementation can positively affect meat quality, morphology, and microbial population in the ileum of Japanese quail we can use this available protein meal in the Japanese quail ration.

The objectives of this study were to determine the effects of feeding rapeseed (27%, DM basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (FA), profile (ratios and indices), enzyme activities from the carcass in lambs fed cereal-based diets. Simultaneously, it was examined the relationship between ingested FA and carcass FA. Samples were obtained from male fattened lambs (n=10, Bulgarian synthetic dairy population, 146-d aged, final body weight FBW=36.95±0.91 kg) involved at two iso-caloric, iso-nitrogenous and equal in calcium: phosphorus (Ca:P) ratio dietary treatments: control-with sunflower meal (SFD) and experimental–with rapeseed meal (RSD). Lipids, extracted from carcass were analyzed for FA profile. Animals feeding RSD had significantly higher (P<0.01) performance (FBW=38.80 vs. 35.1 kg) and meat yield (5.26 vs. 4.67 kg). RSD increased C18:3 (P<0.01) and C18:3 / CLA (P<0.05), but decreased (P<0.01) C18:2 / C18:3 ratio compared with SFD. Deduced relationships between ingested dietary FA and carcass FA shows good parity and high correlation (R>0.55). In conclusion, animals feeding RSD, as a method to modify carcass FAs, decreased the amount of saturated and polyunsaturated FA, and increased monounsaturated, total unsaturated and desirable FAs of carcass.

In this study, chemical compositions of black seed meals samples were determined. 18 male weaning Zandi lambs with an average body weight of 23.5 ±1.5 kg were used in a completely randomized design in three groups of six in individual pens. Experimental treatments were: 1) control (basal diet with 12% soybean meal and without black seed meal), 2) diet containing 6% soybean meal and 9% black seed meal and 3) diet containing 18% black seed meal and without soybean meal. The concentration of dry matter, crude protein, crude fat, NDF, ADF, ADIN, and crude ash of black seed meal samples were 97.53±0.58, 31.26±0.99, 15.16 ± 0.61, 25.95 ± 1.34, 14.2±0.80, 0.69±0.04 and 5.07 ± 0.24, respectively. Replacement of soybean meal with black seed meal in the diet of experimental lambs had no effect on final body weight, daily weight gain, feed conversion ratio, dry matter intake, dressing percentage, tail and total body fat deposition. Albumin and total protein were higher for lambs fed by diet containing 18 % black seed meal compared to other treatments (P <0.05). However, the concentration of blood triglyceride, cholesterol and urea nitrogen were not differed between experimental groups. The digestibility of dry matter, organic matter, crude fat and protein were not affect by feeding of experimental diets. It seems that black seed meal can be used in the diet of fattening lambs up to 18% without adverse effect on performance and nutrients digestibility of growing lambs.

In order to study the effect of rapeseed meal on the serum total protein, albumin, cholesterol, AST, ALT. ALP and LDH in blood serum of broiler chicks, one hundred and sixty broiler chicks were divided into 4 equal groups of 40 each, and each group in four replicates. The chicks were fed diet containing 0%, 15%, 25% and 100% of rapeseed meal in replacement of soya meal up to 42 days. The blood sample was collected from wing vein of five chicks from each group randomly and the above mentioned parameters were measured by routine laboratory methods by automate biochemical analyzer. The results of statistic analysis showed that there was no significant difference between chicks receiving a diet containing rapeseed meal and control group (P>0.05%). ALT in chicks fed diet containing 100% rapeseed meal compared to control group and group fed diet containing 25% rapeseed meal and AST level in chicks fed a diet containing 100% rapeseed meal were significantly higher than other groups (P<0.05). The cholesterol level in chicks fed 25% rapeseed meal compared to the control group, and ALT level in chicks receiving 15% rapeseed meal were significantly higher than other groups at 42 days of age (P< 0.05).
