First- and second-litter progeny from sows fed either 0 or 8% solvent-extracted rapeseed meal in replacement for isonitrogenous amounts of soybean meal and wheat was used to evaluate solvent-extracted rapeseed meal as a protein source. There was no influence of the dam’s diet on gain, efficiency of feed utilization, digestible (DE) and metabolizable energy (ME) or digestible nitrogen (DN) and nitrogen retention in the progeny. In pigs from first litters, the feeding of 8% rapeseed meal, compared with 0% rapeseed meal, depressed feed intake and rate of gain in the finishing period from 55 to 90 kg liveweight, and resulted in reduced gain and poorer efficiency of feed utilization for the overall experiment from 6 kg initial weight. Carcasses from rapeseed meal-fed pigs were leaner. Gilt carcasses were leaner than barrow carcasses. With second-litter pigs, there were no significant differences associated with dietary treatment or sex. There were no significant differences in DE or ME or in DN and nitrogen retention between pigs receiving 0 or 8% rapeseed meal in either the starting diets at 6 weeks of age or the growing diets at 40 kg liveweight.

Tower rapeseed meal was substituted on an isonitrogenous basis for 50, 75 and 100% of the soybean meal in diets for weanling rabbits. There was no significant effect (P < 0.01) on average daily gain or feed efficiency, indicating that Tower rapeseed meal is equivalent to soybean meal as a protein supplement for growing rabbits.

AbstractThe aim of the study was to assess the effect of fermented dried soybean (FSBM) and/or fermented rapeseed meal (FRSM) in diets for weaned piglets on production results, nutrient digestibility, gastrointestinal tract histology, and the composition of the gut microbiota. Piglets in the control group received standard diets with soybean meal. Animals in all experimental groups received diets in which a portion of the soybean meal was replaced: in group FR—8% FRSM; in group FR/FS—6% FRSM and 2% FSBM; in group FS/FR—2% FRSM and 6% FSBM and in group FS—8% FSBM. The use of 8% FRSM or 6% FRSM and 2% FSBM in the piglet diets had a positive effect on average daily gains. Piglets from the FR and FR/FS groups had the highest feed conversion rate. Group FS/FR and FS piglets had significantly lower mortality and lower incidence of diarrhoea. Piglets fed a diet with the fermented components, in particular with 8% FRSM or 6% FRSM and 2% FSBM, exhibited a positive effect on the microbiological composition and histology of intestines, which resulted in improved nutrient digestibility coefficients (ATTD and AID).

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.

The present study was to evaluate the impact of rapeseed meal (RSM), canola meal (CM), and their mixture substitute for soybean meal on performance of lactating sows and their offspring. In total, 16 Yorkshire×Landrace sows with initial BW 258.87±5.36 kg were used in this trial. The experimental period lasted 30 days. The sows were allotted to one of four dietary treatments (4 sows per treatment): 1) corn-soybean meal (SBM) basal diets; 2) basal diets containing 8% RSM; 3) basal diets containing 8% CM; 4) basal diets containing RSM (4%) and CM (4%) mixture (RSCM). Sows fed with RSM and RSCM diets had a higher (P less than 0.05) body weight loss than sows fed SBM diet. The parity, litter number, piglet survival rate, weaning pig number, backfat, ADFI and estrus interval were not influenced by dietary treatments (P greater than 0.05). The ADG of piglets from sows fed SBM was higher (P less than 0.05) than sows fed RSM at 1 week. After farrowing, the apparent total tract digestibility (ATTD) of dry matter in sows fed with SBM diet was higher (P less than 0.05) than the RSCM group. The ATTD of energy in SBM and CM treatments was higher (P less than 0.05) than that in RSM and RSCM treatments. On the weaning day, the ATTD of nitrogen and energy in SBM treatment was highest (P less than 0.05) than other treatments. In conclusion, inclusion of 8% rapeseed meal, canola meal, and their mixture substitute for soybean meal had negative effects on reproductive performance of lactating sows and their offspring.

The use of barley and a protein supplement as a system for intensively finishing calves for beef has been widely used commercially since Preston, Whitelaw, Aitken, MacDermaid and Charleson (1963) originally developed the concept. Once the basic requirements for protein and energy were established the concern of researchers turned to how these requirements could be met at minimal cost. Obviously the most profitable combination of ingredients depends on the prices prevailing at the time, but a variety of raw materials, which may be used to cheapen intensive cereal rations, have been tried experimentally. In the present study the effects of using rapeseed meal (RSM) or maize gluten (MG) as protein supplements to either barley (B) or wheat (W) on the growth and carcass characteristics of Charolais cross Friesian bulls were assessed. The wider availability of double low rapeseed meal (low in both erucic acid and glucosinolates) and maize gluten, combined with their relative cheapness, has made them attractive raw materials for inclusion in ruminant feeds.
