Bonanza barley, containing 11.0% protein, and Glenlea wheat (13.4% protein) were separately supplemented with two levels (10.7 and 18.8%) of low-erucic acid, low-glucosinolate rapeseed (canola) meal (36.3% protein) to provide barley diets and wheat diets containing 13.7 or 16.3% and 15.8 or 17.5 total protein, respectively. One of four pigs, in each of six pens, were allotted to each of the four diets, provided as pellets in individual self-feeders. Access to the assigned diet was restricted to two 45-min periods daily over the period from 26 to 96 kg average liveweight. Pigs fed the 18.8% canola diets had better performance up to 56 kg liveweight but subsequent performance was similar in all groups. Although dietary treatment did not significantly affect carcass data, there was a trend for pigs fed the barley-18.8% canola diet to be superior in measurements of carcass quality. Apparent digestibility of energy and nitrogen was higher for the wheat diets. Assessment of relative palatabilities favored the diets containing 10.7% canola meal.

Sixty-four pigs, fed ad libitum from 24 to 91 kg liveweight, were used to compare the effects upon live performance, carcass measurements and backfat composition of including rapeseed meal, derived from B. campestris (cv. Span) or B. napus (cv. Target), or ground Span rapeseed as 10% of diets based on barley with meatmeal or soybean meal as the source of supplementary protein. A further 32 pigs were similarly fed on barley/meatmeal diets containing 0, 4, 8 or 12% of the ground Span rapeseed. Pigs receiving diets containing Span or Target rapeseed meals grew 5 and 15%, respectively, slower than those fed the control diets (0.75 kg/day). The feed:gain ratio was improved with the Span diets (3.77 vs. 3.87) but not with the Target diets (3.97). Estimates of carcass quality also suggested that the meal from Span was superior. Backfat composition was similar on all rapeseed meal diets. Increasing the level of dietary rapeseed tended to reduce the growth rate by up to 11%, but improved the feed:gain ratio up to 8%, and the carcass quality. At levels exceeding 4% there was a marked increase in the degree of unsaturation of the backfat, reflecting increased proportions of linoleic and linolenic acids.

The effects of substituting canola meal (CM) and ground pea screenings (PM) for soybean meal (SBM) in barley (B)-based diets were determined with a factorial design using 60 male castrates (3 pen−1) over the period 25–97-kg average liveweight. The five mash diets (B/SBM, with 15% SBM; B/CM, with 18.7% CM; B/CMp, with 12.4% CM + 14.1% PM; B/PMc, with 6.1% CM + 28.3% PM; and B/PM, with 42.5% PM) contained 2.4% supplement (minerals and vitamins) and were fed ad libitum. Growth rate (821, 845, 850, 880 and 812 g d−1, respectively, P < 0.06) was increased with the CM–PM blends, but gain:feed was unaffected (283, 289, 294, 298 and 293 g kg−1, P > 0.10). Compared with the SBM-fed pigs, using CM reduced the dressing percent, carcass grade, apparent digestibility of energy and nitrogen but increased liver weight (P < 0.01). The B/PM diet may have been deficient in isoleucine for pigs in the initial weeks, but subsequent performance was not impaired. Compared with B/CM-fed pigs, B/PM pigs had higher carcass grades (P < 0.05) and their lean tissue had relatively more marbling (P < 0.01) and a higher degree of saturated fat (P < 0.01). Differences among the five diets, however, did not affect the sensory evaluation of the cooked lean (P > 0.05). Apart from an apparently lower digestibility of energy and nitrogen, results with the mixed-source diets confirmed that CM and PM were complementary sources of supplementary amino acids for growing-finishing pigs.

True Energy

A factorial digestibility experiment with three dietary levels of canola meal (CM) (0, 15, 30%), two levels of barley hulls (0, 25%) and two basal diets (approximately 10 and 19% crude protein, CP) was conducted using crossbred pigs over the weight range 45 – 90 kg. Diets contained 0.5% chromium oxide as a fecal marker. Inclusion of barley hulls improved the apparent digestibility of dietary CP (83.3% with hulls vs. 81.9% without hulls) and of corn CP (74% for corn, 76% for corn + hulls). True digestibility of CP in corn was also improved (75% for corn, 90% for corn + hulls). The energy and CP components of barley hulls were 40 and 57% digestible, respectively. The digestibility values for CM were: CP 80% (apparent) and 85% (true); energy 68%; nonprotein energy 55% and these were not affected by the presence of barley hulls. Digestibility improved as the pigs matured; each 10-kg weight increase was associated with 0.65 and 0.37 percentage units increase in digestibility of CP and energy, respectively, but these values may be lower than those normally encountered because of the use of casein for adjusting dietary CP levels in this experiment. It is suggested the barley hulls may possess two opposing properties, one that depresses digestibility of protein by increasing metabolic fecal nitrogen output and which is related to the neutral detergent fiber component, and another that in some way enhances the digestibility of protein.

The Mean

Livingston (1962) showed that high levels of dietary protein during pregnancy increased the mean thickness of muscle fibres of M. longissimus dorsi and M. psoas majoris in newly-born piglets. Livingston did not detect this effect in pigs killed at pork weight. Preliminary results of Elsley and MacPherson (1964) indicated that the concentration of dietary protein during pregnancy can influence the nitrogen content of newly-born pigs when birth weight is standardised to 1 kg. to reduce variation; subsequent results (Elsley, MacPherson and McDonald, unpublished data) did not confirm these findings. Any differences attributable to the nutrition of the pregnant sow which are present in the newly-born pig are of practical importance only if they are reflected in changes in subsequent performance.

Sixteen lactating Holstein cows were randomly assigned to treatment sequences in a 4 × 4 changeover experiment. Experimental periods were 28 days in length separated by 7 days for changeover. Cows were fed corn silage free choice and gradually increasing amounts of one of four dairy concentrates containing 0, 11, 22, or 34% rapeseed meal (RSM) of a Canadian, experimental, low glucosinolate–low erucic acid variety. Concentrate intake (kg dry matter/day), milk yield (kg/day) and body weight change (kg/28 days) were 8.45a, 8.71a, 8.37a and 7.17b; 24.40a, 24.03ab, 22.92bc and 21.96c and 7.6b, 22.4b, 13.0ab, and 3.0b for 0, 11, 22 and 34% RSM mixtures, respectively. There was no influence of treatment on milk composition. Ration dry matter (DM) and nitrogen digestibilities declined (P < 0.05) as the RSM in the concentrate mixture increased. The amount of nitrogen excreted in the urine was greatest for cows fed 0% RSM and least for cows fed 34% RSM. Cows fed concentrate mixtures containing 34% RSM had a lower blood thyroxine level than others (P < 0.05), but RSM-containing concentrates had no apparent effect on the conversion of thyroxine to triiodothyronine. Results of the trial indicated that this experimental variety of RSM had no detrimental effect on concentrate intake, DM digestibility, milk composition or thyroid hormone metabolism when included at levels up to 22% in the concentrate mixture. However, milk yield and apparent digestibility of ration nitrogen were decreased (P < 0.05) by the 22% RSM mixture. It was not certain from the current findings whether the depression in digestibility was due largely to the high oil content of the meal or due to the higher fiber content of the RSM-supplemented rations.

Intestinal Digestibility

Abstract Canola was created as a low erucic acid and low glucosinolate seed, to produce high quality oil for human consumption and meal for use in livestock feed. China is an important user of Canadian canola products (seeds, oil, and meal). The extraction of the oil from the seed produces a co-product called canola meal. This meal is rich in protein and is used as a protein source in animal diets. However, differences in the characteristics of the seeds, or processing methods during oil extraction may affect the quality of this co-product. Plus, the synthesis of tissues and milk is related to the amino acids available to the animal for absorption in the small intestine. This study aimed to determine if there are significant differences in the intestinal digestibility (in vitro) of CP and DM between canola seeds and meals from different companies in Canada and to determine if there are significant differences between them in Canada and China. The three-step procedure was applied on residues from a 12-hour rumen incubation in fistulated dairy cows to estimate the intestinal digestibility of CP and DM. There were significant differences (P &lt; 0.05) for TDDM (Total digestible dry matter) and IDP (intestinal digestibility of protein) of the meals between countries. The samples from China had higher TDDM (83.76% versus 81.53%, P = 0.018), while Canada’s had higher IDP (68.51% versus 65.28%, P = 0.016). No significant differences were observed within countries. Based on the material analyzed during this study, it is safe to affirm that there are no significant differences in the digestibility of DM and CP between Canada and China. It was concluded that the quality of the canola seeds or meals produced in both Canada and China were similar when used in dairy rations.
