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.

Twenty-four dairy cows were used in an experiment in which 1) soybean meal, 2) rapeseed meal and 3) rapeseed meal plus urea were compared for feeding value, when given as protein sources in grass silage- and hay-based feeding. About 25 % of the digestible crude protein required for milk production was replaced with these protein sources. The rapeseed meal was mainly of the Span variety. The rapeseed meal composed 13% of a concentrate mixture also containing barley, oats and molassed beet pulp. The daily consumption of rapeseed meal was up to 1.2kg/cow, the average being 1.0kg/cow. As a protein source the rapeseed meal was almost equivalent to the soybean meal. There were no significant differences between the groups in the intake or utilization of the feeds, milk production or milk composition, or liveweight changes. The replacement of silage protein with rapeseed meal or with soybean meal improved the utilization of the protein of the whole ration for milk production.

Abstract Heat processing may enhance nutrient digestibility of diets based on pulse grains. The objective of this study was to determine nutrient and energy digestibility of extruded lentil-based diets containing either supplemental plant or animal protein source in growing pigs. Two diets were formulated to provide 2.4 Mcal NE/kg and 4.35 g standardized ileal digestible Lys/Mcal NE: 1) soybean meal diet (SBM), containing 50% lentil, 31% wheat, and 12.8% soybean meal; and 2) fish meal diet (FM), containing 40% lentil, 45% wheat, and 10% fish meal. Following mixing, each diet was divided into 2 parts: one part remained mash while the other part was extruded using a single-screw extruder (105°C, 400 rpm, 5 kg water/h). The 2 extruded and 2 non-extruded diets were tested in a 2 × 2 factorial arrangement. Eight ileal-cannulated barrows (32.3 kg) were fed the 4 diets at 2.8 times maintenance DE (110 kcal per kg of BW0.75) for four 9-d periods in a double 4 × 4 Latin square. The FM diets had greater (P < 0.05) AID of DM, GE, and most AA, and ATTD of CP, but lower apparent hindgut fermentation of DM and GE than the SBM diets. The AID of CP and AA were 3.2 and 4.7%-units greater (P < 0.05), respectively, and the ATTD of GE and DE values were 2.1 and 3.1%-units greater (P < 0.05), respectively, for the extruded diets than the non-extruded diets. Interactions between protein source and extrusion were not observed. In conclusion, FM diets had greater ileal digestibility of DM, energy, and AA than SBM diets. Extrusion increased the AID of CP and most AA, and DE value of both plant- and animal-protein diets based on lentil grain, indicating that extrusion can increase the energy and protein value of pulse-grain based diets fed to growing pigs.

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.
