“…This is understandable, for the majority of GLS is found in the kernel, so dehulling results in an increased GLS concentration in the remaining fraction. In the first batch of RSM the glucosinolate level (15.5 |LiM/g defatted DM) was similar to that found by Korol et al (1994) in the Ceres variety. In the second batch it was lower (9.99 |LiM/g), similar to the level of aliphatic GLS (9 |uM/g) in the experiment of Kinal et al (1990).…”

Two batches of a commercial double-low rapeseed meal (RSM) were separated into two fractions on sieves with a mesh diameter of 0.5 mm. In the higher-protein fractions (HP-RSM), which constituted about 35% of regular RSM (R-RSM), the crude protein level increased by 16% in the first batch and by 11% in the second, while crude fibre decreased by 19 and 14%, respectively. The glucosinolate (GLS) content rose from 15.5 to 16.7 uM/g defatted DM in the first batch and from 10 to 11.9 uM/g in the second. In both batches HP-fractions contained less methionine and cystine, while more histidine and phenylalanine than R-RSM.Two experiments were carried out, each on 1190 commercial broilers allocated to 14 pens on litter. In both experiments the birds were fed starter diets without RSM for the first three weeks. In the grower and finisher diets soyabean meal (SBM) was substituted, partially or totally, by R-RSM or HP-RSM.In Experiment 1 control broilers were significantly (P<0.01) heavier than those from the experimental groups, and birds receiving R-RSM were heavier (P<0.05) on day 48 of life than those given HP-RSM. In Experiment 2 there were no significant differences between the weight of birds receiving SBM or RSM in the diets, however, those given HP-RSM were slightly lighter. In Experiment 2 chickens fed RSM had larger livers (PO.05) and thyroids (PO.01) than the control birds.In both experiments feed conversion efficiency in RSM-fed groups was poorer than in control one, even when the available lysine level was not lower than in the control diet.

“…The level of total glucosinolates in the seed (11.2) and in the meal (21.78 mmol/kg) produced from 00-cultivar Silvia rapeseed is below the average values found in the five Polish 00-cultivars with a low level of glucosinolates (Korol et al, 1994). Chemical analysis established that the glucosinolate structure of the Silvia cultivar is similar to that found in Polish and Canadian rapeseed cultivars (Slominski, 1998).…”

“…In parallel with the introduction of new 00 cultivars to agricultural production, numerous experiments with feeding diets were carried out involving broiler chickens, where different quantities of rapeseed meal were fed as a source of protein and energy. The high content (13.5%) of crude fibre (Mawson et al, 1993), as well as of glucosinolate, tannin and phytate (Korol et al, 1994), proved to be a limiting factor in the application of greater quantities of rapeseed meal in chicken feed. Wetscherek et al (1993) fed their chicks with a fodder diet consisting of modern-day 00 cultivars of rapeseed meal in quantities of 0, 8, 16 and 24% and with a feed diet containing 24% rape cake.…”

Research was focussed on investigating the influence of different quantities (0, 10, 20 and 30%) of rapeseed meal (RM), 00-cultivar Silvia on production results, as well as on the morphological and pathohistological changes in the internal organs of chicks during the course of the experiment, measured on the 21st and 42nd days of the 42-day experiment. The experiment involved 120 chicks divided into four groups: a control group (C) and three experimental groups (E 1-3 ). It was found that chicks in Groups C, E 1 and E 2 realised significantly (P < 0.05) higher gains than those in Group E 3 , both after the test period and at the end of the experiment. No significant differences with regard to feed conversion were found between groups of chicks. Throughout the experiment chicks in Groups E 1-3 were found to have a significantly (P < 0.05) heavier liver. Compared to Groups E 1-3, Group C chicks had a significantly (P < 0.05) heavier gizzard after 21 days, but following the finisher diet Group E 3 had a significantly (P < 0.05) lighter gizzard. Compared with birds in Group C, those in Groups E 2-3 had significantly heavier (P < 0.05) unevacuated intestines when fed the starter diet, and those in Groups E 1-2 showed a similar result when fed the finisher diet. Chicks in Group E 3 had a significantly lower grill weight than those in Groups C, E 1 and E 2 , both in the first half of the experiment and at the end. The starter diet did not result in any differences in the quantity of abdominal fat among groups, but following the finisher diet Groups E 2-3 showed significantly less abdominal fat in comparison to Groups C and E 1 (P < 0.05). Group C showed a significantly higher carcass yield than Groups E 1-3 (P < 0.05) in the first half of the experiment and at the end. Groups E 1-3 manifested a slight to medium hypertrophy of thyroid epithelial tissue as well as slight thymus hypertrophy and slight atrophy of the cloacal bursa follicles.

“…The content of saturated (5.05%) and unsaturated (94.78%) fatty acids in the lipid fraction of this cultivar was higher than in other double zero cultivars (Banaszkiewicz, 2000). Korol et al (1994) recorded some differences, especially in palmitic, oleic, eicosenoic and erucic acid contents in rapeseeds. The total glucosinolate content (14.5 µmol g -1 ) did not exceed 25 µmol .…”

The studies were designed to determine an effect of partial replacement of soybean meal with rape cake supplemented with enzymes on the nutritional value of diets and the number of lactic acid bacteria (LAB) in the ileum and caecum of broilers. The experiment 1 (growth trial) was carried out on 120 one-day-old broiler chickens Ross 308 which were randomly divided into four homogenous groups, 30 birds per group (15 males and 15 females). Each treatment consisted of six replicates of 5 birds. A control diet contained soybean meal whereas in the experimental, a part of the soybean meal was replaced by 15% rape cake from the Kaszub cultivar and supplemented with enzyme preparations containing xylanase or phytase added individually or in combination. On the 21st day of experiment six birds from each group were scarified and the ileum and caeca were isolated for lactic acid bacteria (LAB) determination. The experiment 2 (digestibility trial) was carried out on 60 sevenday-old chickens divided into four treatments of 20 birds (4 replications of 5 birds) to determine nutrient digestibility of diets used in the growth trial. The digestibility test was carried out by the total collection method. The inclusion of 15 % rape cake instead of soybean meal and the addition of enzyme preparations did not decrease body weight gain and feed intake. The feed conversion ratio (FCR) was higher in the group fed the diet in which phytase was added separately. A simultaneous application of xylanase and phytase statistically (P<0.05) increased the digestibility of crude fibre and N-free extracts. The lactic acid bacteria number was the highest in the caecum and ileum of birds fed the diet containing the xylanase preparation, whereas xylanase and phytase preparations added in combination had no effect on lactic acid bacteria number
