Poultry Diets

Two experiments were carried out to investigate the value of rapeseed meal in poultry diets. In the first experiment when rapeseed meal replaced all of the supplemental soybean protein in a corn, soya-type pullet growing diet, weight gain was significantly reduced as compared with the corn, soya control diet. The difference, however, was small and may well have been due to amino acid imbalance. In the second experiment rapeseed meal effectively replaced soybean meal in a laying hen diet when fed in a phase-feeding program. For the overall test, the only difference in the phase-fed groups compared with birds fed the higher protein soybean meal control diet was a significantly lower weight gain from the diet where rapeseed meal replaced all of the soybean meal protein, and a decrease in average egg weight from the diet where rapeseed meal replaced half of the soybean meal protein.

The One

Six hundred and seventy-two 1-day-old male broiler chicks of two strains were used to assess the effects of diet and color of diet on feed consumption. Isocaloric isonitrogenous diets that contained soybean meal (control), rapeseed meal, or ground rapeseed were fed in either colored or noncolored form. During the starter period the birds were given a choice of two diets in various combinations whereas during the grower period no choice was available. In the starter period there were no significant effects of color or diet combinations on total feed consumption. Coloring one diet of a pair, however, tended to increase the difference in consumption between the two by reducing the intake of the colored diet. The one exception to this was the diet pair containing ground rapeseed, which was not affected when one diet was colored. The control diet was preferred, followed by the diets containing rapeseed meal and ground rapeseed, respectively, when a choice was available. When no choice of diet was available in the grower period the only significant effect of color was to increase consumption of the ground rapeseed-containing diet. Weight gain in both periods was highest on the control diet followed by the diets containing rapeseed meal and ground rapeseed, respectively.

The Difference

Rations containing 10, 20 and 30% of rapeseed meal respectively were fed to Large White turkeys starting at 1 day of age. The results at 56 days showed a significant linear decrease in weight gain and feed utilization when compared with an isocaloric and isonitrogenous corn–soybean basal diet. Steam-pelleting the diets reduced the difference in weight depression observed between the control and rapeseed meal diets as compared with similar diets fed in the form of mash. At 113 days, the levels of rapeseed meal in the diets were reduced in order to maintain desired dietary protein levels. Weight gain and feed utilization were still significantly lower at market age for the rapeseed-fed birds as compared with those on the control diet. Analyzing the weight-gain and feed-utilization data from 57 days to the conclusion of the experiment suggested that most of the adverse effects of rapeseed meal were encountered with birds up to 56 days of age.

With the objective of investigating shrimp waste (SWM) and cassava leaf (CLM) meals as cheap alternatives and protein source mixtures that would best complement cassava root-soybean ration in total replacement for maize in broiler diets, six iso-energetic and iso-nitrogenous diets were evaluated using two weeks old Anak broilers in a growth and digestibility trial lasting seven weeks. Diet I was a maize-soybean based control diet while diets 2 to 6 contained whole cassava root meal (WCRM) in total replacement for maize, energy for energy. Diet 2 had soybean meal (SBM) as a major source of protein taking the protein supplied by SBM in diet 2 as 100%, SBM, CLM and SWM were combined thus in diets 3/0.5SBM: 0.5SIM), 4 (0.5SBM: 0.25SWM: 0.25CLAI), 5(0.25 SBM: 0.5SWM: 0.25CLM) and 6(0.5 SWM: 0.5 CL11). Average daily feed intake, weight gain (P< 0.01) and efficiency of feed conversion (P<0.05) were significantly influenced by dietary treatments. Results indicate that replacing up to 50% supplemental protein of soybean meal with equal proportion of supplemental protein from SWM and CLM had no deleterious effects on rate and efficiency of weight gain in broiler chickens. While nutrient and energy digestibility and carcass characteristics except dressing percentage were unaffected by dietary treatment, there was indication that organs such as gizzard and small intestine were significantly tasked for digestive function, evident from the considerable increase in their weights in birds fed diets in which over 50% of soybean protein was replaced by SWM and CLM. Based on the observation from this study, it can be concluded that not more than 50% of the dietary protein contributed by soybean should be replaced by SWM and CLM as doing otherwise would bring about a worsening effect on the performance of broilers.

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

Thirty dairy heifer calves were reared from birth to calving on rations containing 0, 6.8 or 13.7% rapeseed meal in substitution for soybean meal. The level of rapeseed meal did not significantly (P > 0.05) affect feed intake, weight gain or feed efficiency of heifers up to breeding weight (330–340 kg). The level of rapeseed meal did not significantly (P > 0.05) affect reproduction or milk production during the first lactation. However, there may have been a trend for lower conception rate and milk fat production during first lactation with the higher level of rapeseed meal.

Thirty male Holstein calves were utilized in a 2 × 3 factorial experiment designed to compare rapeseed meal (cv. Candle) and soybean meal as protein supplements and 0, 10, and 20% levels of protected lipid as a form of supplemental energy for starter rations. The six rations were fed free choice from 21 to 70 days of the experiment with whole milk fed at 10% of body weight from 0 to 42 days. Starter intake was similar for the two protein sources but significantly less for the ration containing 10% protected lipid compared to either the 0 or 20% levels. Body weight gain was faster for calves fed the starter containing 20% protected lipid compared to those fed the 10% level. Efficiency of feed conversion was greater for calves receiving protected lipid. There were no differences between protein source in dry matter intake, body weight gain, efficiency of feed conversion, apparent dry matter digestibility or dressing percent. Plasma glucose and percent hematocrit were significantly lower and percent kidney fat significantly higher for calves fed starter rations containing soybean meal. The relative availability of copper was reduced significantly when soybean meal or 20% protected lipid formed part of the starter diet. It was concluded from this study that Candle rapeseed meal was a suitable source of supplemental protein for calf starter diets and that the inclusion of protected lipid improved feed conversion of calves from 43 to 70 days of age.

ABSTRACTLive-weight gain responses were investigated using 36 individually penned lambs (mean live weight 35·2 kg) given three sodium hydroxide treated straw-based diets: low-protein, low-rapeseed meal (control) diet; high protein, high-rapeseed meal (HR) diet; or high-protein, fish meal (FM) diet. The diets were formulated to provide 3 or 9 g undegradable nitrogen per kg dry matter (DM) respectively for the diets without or with fish meal. Diets were offered once a day in a 50: 50 forage-to-concentrate ratio in amounts calculated to support maintenance plus 150 g gain and were adjusted weekly according to live weight. Live-weight gain, measured for 7 weeks, was improved by the FM diet only (P < 0·05).The three diets were given also to rumen-fistulated sheep. The FM diet maintained higher rumen ammonia concentrations during most of the day. The FM and HR diets reduced rumen solid particle outflow rate (P < 0·05) and increased the effective degradability of DM and acid-detergent fibre.

Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the to asted meal (1.01 vs. 15.58 µmol g-1). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g-1), 2-OH-3-butenyl (5.47 µmol g-1) and 4-OH-3-methylindoyl (4.68 µmol g-1). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal.

Diets containing canola and soybean meal as the only source of protein and containing no supplemental niacin, choline or thiamine were fed to male broiler chickens from 1 wk to 6 wk of age. Supplementation of the basal diet with various levels of the vitamins failed to significantly alter weight gain, gain:feed ratio or percent bone ash values. Examination of the birds for leg deformities and difficulty in walking showed no difference between the basal and the vitamin-supplemented diets. It was concluded that the three vitamins investigated would not be factors in problems arising from the substitution of canola for soybean meal in practical type broiler diets.

Diets containing 10 and 20% of either prepress-solvent commercial rapeseed meal or thioglucoside-free Bronowski rapeseed meal were fed to Large White turkeys from 6 days of age to market at 144 days. Twenty percent commercial rapeseed meal depressed gains in comparison with an isocaloric and isonitrogenous soybean meal control diet. The performance of turkeys fed Bronowski rapeseed meal was essentially equal to that of birds fed the control diet. Diets containing 10% commercial rapeseed meal and 10 or 20% Bronowski meal were utilized more efficiently from 55 to 111 days than from 6 to 55 days of age when compared with the control diet.
