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.

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.

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.

Fattening Pigs

Rapeseed meal (RSM), a by-product of extracted rapeseed oil production, is a potential protein source for use in pig diets. To determine the best levels of RSM inclusion in diets of fattening pigs as well as the digestibility and energy value of diets containing gradually increasing levels of RSM, a digestibility trial was conducted. The trial was performed according to a 4x4 Latin square experimental design, with 4 Large White x Landrace castrated male pigs weighing on average 47.3kg. The animals were housed in metabolism cages during the whole period the duration of which was a total of 66 days. The experiment was divided into 5 periods, an adjustment period and 4 experimental periods, during which pigs consumed 4 experimental diets. The diet C (control) was a basal diet based on corn and soybean meal, while the other experimental diets included RSM at levels 90 (low- L), 180 (medium- M) and 270 (high- H) g.kg-1 of feed, respectively. Each experimental period consisted of 10 preliminary days during which the animals were adapted to the diets, followed by a 4 days period for collection of faeces, urine and feed refusal. The gradual increase in the level of RSM in the experimental diets resulted in a significant (P<0.05) reduction in the apparent digestibility of CP, but only for the diet with the highest level of RSM, compared to the control diet and this one with the lowest level of RSM . Any increase in the level of RSM in the experimental diets resulted in significant (P<0.05) increase on the apparent digestibility coefficient (ADC) of CF and very significant (P<0.01) increase in diets M and H, compared to the control and diet L. Similar were the effects of RSM levels in the diets on the apparent digestibility coefficient of NDF, ADF and cellulose. As conclusion, the gradual increase in the level of RSM in the fattening pigs’ diets did not significantly affect ADC of DM and gross energy, caused a significant reduction in the ADC of CP, and a significant improvement in the ADC of CF as well.

Sixty (60) grower-finisher pigs (Landrace x Large white) were used to investigate the nutritional value of beniseed hull (BSH) as substitute for maize on performance, carcass, and organs characteristics of the experimental animals. Five experimental diets were formulated by incorporating BSH into basal diet to replace maize at 0, 25, 50, 75 and 100%; designated as T1 (control), T2, T3, T4 and T5, respectively. The experimental pigs were individually weighed and assigned to five dietary treatments of three replicates of four animals each in a completely randomized design. The animals were fed for 2 weeks pre-experimental period and thereafter for ten weeks during which data were collected. Feed cost per kg live weight gain (? 668.67) of the animals fed 0% BSH significantly (P<0.05) reduced to ? 620.06 (25% BSH), ? 527.24 (50% BSH), ? 509.74 (75% BSH) and ? 456.73 (100% BSH). The bled weight, scald weight, eviscerated weight, dressing percentage, bacon, fore hock, hind hock and tail were significantly (P<0.05) affected by dietary treatments. The biggest liver weight (2.27g/kg) obtained in the animals fed the control diet (0% BSH) reduced significantly (P<0.05) to 2.20 (25% BSH), 1.91 (50% BSH), 1.76 (75% BSH) and 2.00 (100% BSH). Variations obtained in the kidney weight (0.40 g/kg) of the experimental animals fed with 25% BSH-based diets were similar (P>0.05) to 0.38 g/kg in the control (0% BSH) with both significantly (P<0.05) reduced to 0.36 (50% BSH), 0.36 (75% BSH) and 0.32 (100% BSH), respectively. Beniseed hull (BSH) poses no health challenge to the pigs used in this study. There were reductions in the cost/kg and cost of feed per kilogram live-weight gain with increasing levels of BSH in the diets, the lowest being at 100% level of substitution; beniseed hull could economically and safely replace maize in pig's diets up to 100% level.

Dietary Treatments

Four replicate groups of 22 male large white day-old poults were assigned to each of eight dietary treatments. These consisted of a corn–soybean meal control diet and isocaloric, isonitrogenous diets containing either 25% Target, high-glucosinolate, rapeseed meal (RSM), 25% Tower, low-glucosinolate RSM derived from two sources or 21.5% whole autoclaved Tower rapeseed plus three other treatments where 10% of oil derived from either soybean, Tower rapeseed or Target rapeseed was added. Dietary specifications were changed with age of bird. Weight gain and feed intake were recorded to 112 days of age. Target RSM resulted in a significant depression in weight gain and feed intake. Compared to the corn–soybean control, 25% Tower RSM and whole autoclaved Tower rapeseed, which supplied most of the dietary fat, had no effect on turkey performance. There was an indication that poults to 56 days of age were not able to fully utilize whole rapeseed. Performance of turkeys fed Tower rapeseed oil or soybean oil was similar, while Target oil significantly depressed weight gain. A perotic-type condition was observed in poults to 28 days of age when fed diets containing Target RSM. The condition was not observed in poults fed the other diets. It is concluded that both the oil and meal resulting from the processing of Tower rapeseed are superior in nutritional value to those obtained from Target rapeseed, and that these products may be included in turkey diets from day-of-age up to 10% for the oil and 25% for the meal, without adversely affecting performance.

Mustard Meal

Wild mustard seed (Brassica kaber), stinkweed (Thlaspi arvense) and rapeseed (B. napus 'Tower') were fed in diets for growing mice as ground raw seed and as cooked, petroleum ether-extracted meals. In exp. 1, wild mustard seed at 0, 2 or 4% and stinkweed seed at 0, 1 or 2% were substituted for part of the rapeseed in a 3 × 3 factorial design. The control diet contained 20% rapeseed and casein was used to equalize protein levels at 16%. Growth and feed utilization were not affected (P > 0.05). The failure of diets (exp. 1) with 14 – 20% rapeseed and up to 6% weed seeds and containing active myrosinase to depress growth more markedly, is attributed to the relatively low total glucosinolate levels in the diets. In exp. 2, the meals from wild mustard, stinkweed and rapeseed were compared with soybean meal in diets in which each meal provided 3, 6 or 9% protein, with casein used to bring dietary protein to 16%, in a 3 × 4 factorial design. Weed seed meals resulted in lower feed intakes (P < 0.05), with wild mustard meal being the lowest. Increasing levels of wild mustard seed meal and stinkweed seed meal reduced growth rates (P < 0.05), but it is concluded that such meals as contaminants of normally processed commercial rapeseed meal can be fed at relatively high levels in myrosinase-free diets without risk associated with glucosinolates.

Two 8-week feeding trials were conducted to determine the dietary Na requirement for juvenile hybrid tilapia (Oreochromis niloticus × O. aureus) reared in fresh water and seawater. In each experiment, NaCl was added to the basal diet at 0, 0·5, 1, 2, 3, 5, or 7g Na/kg diet (fresh water) and at 0, 0·2, 0·5, 0·8, 1·2, 1·5, 2, or 3g Na/kg diet (seawater). Each diet was fed to three replicate groups of fish, individual fish initially weighing 0·69 (se 0·01) g, in a closed, recirculating rearing system. In fresh water, the tilapia fed the diet supplemented with 2g Na/kg diet had significantly (P<0·05) greater weight gain than the fish fed the diets supplemented with ≥3 and ≤0·5g Na/kg diet. Feed efficiency (FE) in fish generally followed the weight-gain pattern. Gill Na+–K+ ATPase activity was highest in the fish fed the diets supplemented with 1–3g Na/kg diet, followed by the fish fed the diet with 7g Na/kg diet and lowest in the fish fed the unsupplemented control diet. In seawater, the weight gain, FE and gill Na+–K+ ATPase activity in fish were not affected by the dietary treatment. Analysis by polynomial regression of weight gain, by broken-line regression of gill Na+–K+ ATPase activity and by linear regression of whole-body Na retention of the fish reared in fresh water, indicated that the adequate dietary Na concentration for tilapia is about 1·5g/kg diet. The present study also suggests that no dietary Na is required for tilapia reared in seawater.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.

The study was undertaken to investigate the effects of concentrate supplementation with different protein levels on intake, digestibility and growth performance of Red Chittagong (RC) heifers fed urea molasses straw (UMS) based diet. Twelve RC heifers having average live weight of 124.83±43.15 kg and aged between 8 to 14 months were selected for 90 days feeding trial. Animals were divided into four groups having three animals in each and were randomly assigned to four dietary treatments in a Randomized Block Design (RBD). The experimental diets were formulated using urea molasses straw (UMS), German grass (Echinochloa grousgalli) with or without concentrate mix (having different levels of protein). All the animals received UMS ad libitum and German grass at the rate of 20% of total DM intake. In addition to UMS and German grass of control diet T0, animals on diets T1, T2 and T3 were supplied with concentrate mixture at the rate of 10% of DM intake containing 15, 20 and 25% CP, respectively. Average daily DM intake was 2.65, 3.06, 2.62 and 2.86 kg/100 kg LW for diets T0, T1, T2 and T3, respectively and the difference was non significant (P>0.05). The digestibility of DM, CP, EE, NFE and digestible nutrients (DCP, DEE and DNFE) for diets T1, T2 and T3 was significantly higher than those for diet T0. The daily average liveweight gain of RC heifers fed diets T0, T1, T2 and T3 were 100, 275, 333 and 291 g respectively (P<0.01). Concentrate mixture having 20% crude protein may be supplemented at the rate of 10% of DM intake per day for optimum growth of Red Chittagong heifers.
