Digestibility and nutritive value for growing pigs, liveweight 40-70 kg, were determined for high glucosinolate (HG) Span and Torch (Brassica campestris) rapeseed meals (RSM) and cakes (RSC), and for low glucosinolate (LG)Regent (B. napus) RSM and DF-15 (B. campestris) RSC in barley based diets in one year or two successive years. Some of the feeds were evaluated also for sheep. The level of RSM and RSC was 20 or 30 % of diets for pigs and 32 % for sheep. The observed net energy value of commercial Span-Torch RSM for pigs was in two successive years 0.80 and 0,79 f.u./kg dry matter (DM) ( f.u. = feed unit = 0.7kg starch equivalent).The protein values were 281 and 291 g digestible crude protein (DCP)/kg DM, respectively. The 8 %-units higher fat content together with a little better digestibility of organic components raised the f.u. value of RSC about 30 % above that of RSM. For pigs there were only slight differences in the digestibility and palatability of the HG Span-Torch and the LG Regent and DF-15 meals and cakes, but there was a clear difference in the palatability in successive years. The nitrogen balances for pigs on the RSM or RSC and barley diets were 20.4-22.2 g N/d, and the biological values of protein of the RSM and RSC were 67-68. The net energy value of Span-Torch rapeseed meal for sheep was 0.91 f.u./kg DM, and the protein value 309 g DCP/kg DM. The digestibility of cakes was nearly equal to meal, but the 8 %-units higher fat content raised the f.u. value of RSC about 20 %. The digestibility of organic matter of LG DF-15 cakes was a little better (P < 0.05) than that of Span-Torch cakes. The sheep willingly ate RSM and RSC at a 32 % level of the diets.

Abstract Carinata (Brasicca carinata) is an oilseed crop of brassica family that is grown for production of oil for biofuel industry. Expeller-pressed carinata cake (EPCAR), a co-product from carinata seed oil extraction plants, is available for livestock feeding. However, nutritive value of EPCAR for pigs has not been reported. Objective of this study was to determine standardized ileal digestibility (SID) of amino acids (AA) and net energy value of EPCAR for growing pigs. Eight ileal-cannulated barrows (initial BW = 33 kg) were fed 3 diets in a replicated 3 × 3 Latin square design with 2 added columns to give 8 replicates/diet. The diets were cornstarch-based, containing expeller-pressed canola cake (EPCAN) or EPCAR as sole protein source, and N-free. The EPCAN was included in the study for comparison because it is derived from canola, which is the most widely used crop of Brassica family for oil production. Digestibility of AA in feedstuffs was determined by the direct method. Energy digestibility in EPCAN and EPCAR was determined by difference from the N-free diet. On DM basis, EPCAN and EPCAR contained 39.6 and 50.2% CP, 20.7 and 26.8% NDF, 16.0 and 0.88% ether extract, 2.32 and 1.82% lysine, 0.74 and 0.96% methionine, 1.63 and 1.89% threonine, and 0.50 and 0.64% tryptophan, respectively. The EPCAN compared with EPCAR, had greater (PPP = 0.078) in SID of threonine. The EPCAN had greater (P < 0.05) net energy value than EPCAN (2,082 vs. 1,576 kcal/kg DM). In conclusion, EPCAR lower energy value than EPCAN. However, EPCAR had greater SID of most AA than EPCAN; therefore, EPCAR can serve as alternative oilseed co-product feedstuff for pigs.

Reversal Design

Six barrows, with an average initial body weight of 88 kg, were used in a digestibility and balance experiment to study the nutritive value of meat and bone meal (MBM). The MBM, which contained 478 g crude protein and 322 g ash/kg dry matter (DM), was included in barley-based diets at two levels: 100 and 200 g/kg. The experiment was conducted according to a two-period reversal design. The apparent digestibilities of organic matter, crude protein and crude fat in the MBM were 0.910, 0.909 and 0.730, respectively. The MBM was calculated to contain 434 g digestible crude protein, 14.26 MJ metabolizable energy and 8.82 MJ net energy/kg DM. The efficiency of nitrogen utilization decreased with an increasing MBM supply. Due to relatively high mineral intakes, the apparent digestibilities of calcium and phosphorus remained low.

The Difference

Two experiments (Exp.) were conducted to determine the nutritive value of wheat-derived wet concentrated distillers solubles (CDS) for growing pigs. In Exp. 1, standardised ileal digestibility (SID) of amino acids (AA) was determined by the difference method, using six ileally cannulated barrows (initial bodyweight (BW) of 31 ± 2.9 kg). The pigs were fed a casein-corn starch-based diet supplemented with wheat CDS so that about half of the crude protein (CP) originated from either wheat CDS or from casein. In Exp. 2, 12 barrows with an initial BW of 17 ± 0.9 kg were used to determine digestible energy (DE) content, and to calculate metabolisable energy (ME) and net energy (NE) content of wheat CDS. Animals were fed either a casein-corn starch-based basal diet or a CDS diet containing 470 g/kg of the basal diet and 530 g/kg wheat CDS on a dry matter (DM) basis. Values of SID of CP and AA in Exp. 1 amounted to 85, 74, 83 and 70% for CP, lysine, methionine and threonine, respectively. The DE, ME and NE contents of wheat CDS were 16.8, 15.8 and 11.1 MJ/kg DM, respectively. It can be concluded that SID of CP and AA and also the energy content in wheat CDS are substantially higher than corresponding values reported in international tables with information on nutritional value of dried co-products of bioethanol production.

Growth Trial

The nutritive value of five lots of rapeseed meal (RSM) from Brassica campestris or B. napus with different levels of glucosinolates (GL) was investigated in a digestibility and balance trial with a 5 x 5 Latin square design and in a growth trial with 140 growing-finishing pigs. The RSM’s were prepared from the cultivars: Span-Torch, Sigga, Gulliver and Topas, and a heat-treated RSM was also studied, their total GL contents (µmol/g defatted meal) being 42, 11, 98, 27 and 8, respectively. Cv. Sigga had yellow hulls and a lower ADF content than the other cultivars. The hat-treated RSM had a reduced lysine content. There were no significant (P > 0.05) differences in organic matter or crude protein digestibilities between the RSM’s with different GL levels or the RSM’s prepared from B. campestris and B. napus, when RSM was used as the only protein supplement at a level of 20—25 % in a barley-based diet. Heat treatment reduced the organic matter and crude protein digestibilities (P < 0.01). Nitrogen retention and protein utilization were lower (P < 0.01) on the diet supplemented with heat-treated RSM than on the diets with the other RSM’s but otherwise there were no significant differences between them (P > 0.05). In the growth trial supplementation with HGL-RSM Gulliver (14 % in diet) caused some palatability problems and this led to reduced performance (P < 0.05), but there were no differences between the other groups receiving 14—15 % RSM and the SBM control group (P > 0.05). The carcass quality was similar in all the groups. The weight of the thyroid gland was higher in the pigs receiving RSM than in the SBM controls, by 6—57 % (P < 0.05). In the present study a fairly high RSM supplements from cultivars with a moderate high GL content could be used in the diet of growing pigs without impairing their performance, when the diet was formulated on the basis of the digestible nutrients of RSM. Heat-treated RSM, with protein of low rumen degradability, is of poor value in pig feeding due to the low digestibility and availability of its protein.

1. Eighteen determinations of the energy retention of six sheep were made when they were given the same batch of dried grass in the form of chopped material or as cubes. The cubes were made following hammer milling to a medium and fine particle size. The fasting heat production of each sheep was also determined, following subsistence on a standard ration.2. Agreement between determinations of energy retention calculated from the carbon and nitrogen retentions and from the energy exchange was good. The mean discrepancy was 4 Cal./24 hr.3. There were no statistically significant differences in energy retention as between the three materials at either a low (600 g./24 hr.) or a high (1500 g./24 hr.) level of feeding. Calculations of net energy/100 Cal. of food ingested showed that higher values occurred at the lower level of feeding. Standard errors of the means were small, about ±3% of the determined values. Further analysis showed that no large differences in the net energy value of the materials would appear within the normal feeding range, but slight extrapolation of the data indicated that the cubes would be superior at high feeding levels.4. Faecal losses of energy were considerably greater when cubes were given and methane losses were much smaller. Individual sheep which showed low methane losses also showed high faecal energy losses. Faecal losses of energy were smaller at the lower feeding level. Urine energy losses were unaffected by the amount or physical form of the food given.5. Heat losses were greater at the higher nutritional level and were considerably less for cubes than for chopped material. Constancy of net energy value in this study thus involved compensation of high faecal energy losses by low losses of energy as heat and methane.6. The determinations of the digestibility of the carbohydrate fractions of the grass showed that a fall in the digestibility of the structural components of the cell was the major factor causing increased faecal losses. The digestibility of intracellular constituents fell very much less.7. It is shown that evaluation of the grasses in terms of metabolizable or digested energy does not place them in their correct physiological order of nutritive value, and that estimates of nutritive value using Kellner's and other factors do not give their true nutritive worth.8. It is pointed out that physical factors, which change the rate of passage of food through the gut, change the rate and nature of the microbial fermentation, and cause variation in the mechanical work involved in prehending, masticating and cudding food, are as important as the chemical composition of the food in determining its nutritive value.

The digestibility and nutritive value of two rapeseed meals (Brassica campestris) , one prepared from the medium-glucosinolate varieties Span and Torch, and the other from a low-glucosinolate variety Candle, were determined for three pigs weighing about 45 kg. The pigs received 1600 g barley and 600 g rapeseed meal daily. The composition of the Candle meal was better than that of Span-Torch and its digestibility and nutritive value higher (P < 0.01). When the fat content of Candle meal was corrected to the 1.5 % level of Span-Torch meal, the ME values were 13.6 and 10.4 MJ/kg DM, the NE values 1.01 and 0.78 FU/kg DM (FU = 0.7 kg starch), and the DCP values 318 and 248 g DCP/kg DM for Candle and Span-Torch, respectively (P < 0.01). The difference in the nitrogen balance was also significant (P < 0.01). Thus the Candle meal has about 30 % higher nutritive value for pigs than the Span-Torch meal.

Crossbred Pigs

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

SUMMARYIn two grasses of low net energy value for growth and fattening of cattle, digestible cell-wall values were close to 40% of forage organic matter (OM), similar to the expected value for grass. A value of 14% of forage OM for apparently undigested cellular contents in both grasses was just outside the range of values for grass. The data supported previous evidence that total cell wall is the only value that can be used at present to define grass in terms of its digestible dry matter.
