Two very low glucosinolate (VLG) canola meals from crop years 1987 and 1988 (CM; 1.66 and 0.53 μmol g−1) and two Tobin CM (B. campestris) (10.71 and 15.62 μmol g−1) were evaluated in experiments with pigs. In exp. 1, 1987 Tobin CM, VLG-CM and soybean meal (SBM) were compared in individually fed meal and pelleted diets. Daily gains from 23 to 57 kg were similar for the CMs (VLG-CM 662 g, Tobin CM 645 g) but lower than those obtained with SBM (730 g; P < 0.01). Daily feed intakes of pigs fed CM were lower than for those fed SBM (P < 0.05). Plasma thyroxine (T4) levels were similar for SBM and VLG-CM and were above those from pigs fed Tobin (P < 0.05) CM. Triiodothyronine (T3) levels were lower for VLG-CM than for SBM (P < 0.05) and the T3 value for Tobin CM was intermediate. Pelleting enhanced T3 (0.70 vs 0.94 ng mL−1) and T4 (50 vs. 60 ng mL−1) levels with all protein supplements (P < 0.01). In exp. 2, similar diets were fed ad libitum. Daily gains for SBM were greater than for Tobin CM (803 vs. 744, P < 0.05) and gains for pigs fed VLG-CM was 774 g. Daily feed intakes were similar (2.01, 1.99 and 1.92 kg). In exp. 3 energy digestibility of 1987 VLG-CM was greater (P < 0.01) than for Tobin CM (75.0 vs 67.4% for 30-kg pigs). Apparent digestibility coefficients of crude protein (CP) were 71.9, 71.2 and 71.6 in 16% CP diets. In exp. 4 Tobin and VLG-CMs from 1987 and 1988 crops were compared with SBM and commercial CM using 96 pigs (48M, 48F). Daily gains and feed intakes were similar for the CMs but T3 and T4 values were below those of SBM (P < 0.05). Key words: Canola meal, very low glucosinolate, digestibility, feeding value, pigs

Forty-eight lambs (29.0 ± 4.7 kg BW) were used to study the effects of protein supplementation of forages on performance and diet digestibility. Lambs were fed grass hay or silage ad libitum plus a daily supplement of either: C, a control supplement supplying 1.2 g kg−1 BW of dry molasses and 0.6 g kg−1 BW of minerals, vitamins and lasalocid; CM, control supplement + 5.48 g kg−1 BW of canola meal; or FM, control supplement + 3 g kg−1 BW of fish meal. Apparent digestibility of all dietary components was higher in lambs fed silage than in those fed hay (P < 0.04). Addition of CM or FM improved apparent digestibility of energy and crude protein (CP) of lambs fed hay (P < 0.02) and CP digestibility of lambs fed silage (P < 0.01). Apparent digestibility of CP was higher in lambs fed FM than in those fed CM with either hay or silage (P < 0.03). Addition of CM or FM tended to decrease ADF digestibility of silage-based diets (P < 0.06). Apparent ADF digestibility of hay-based diets was lower in lambs fed CM than in those fed FM (P < 0.02). Forage DM intake was similar for all treatments. Addition of CM or FM to the diets improved average daily gains by 24% (P < 0.03), an effect that was higher with hay (35.1%, P < 0.02). Feed efficiency was 23.6% better in lambs fed protein-supplemented hay than in those receiving C (P < 0.04). Neither dressing percentage nor carcass lean yield was affected by protein supplementation. Digestible DM and TDN intakes were higher in lambs fed silage (P < 0.03) as a result of higher apparent digestibility for silage than hay. Furthermore, CM increased TDN intake by 7.6 and 8.2% in lambs fed hay and silage, respectively, compared with lambs fed FM. Addition of canola and fish meals improved forage nutritive value for lambs. Key words: Canola meal, fish meal, forages, digestibility, lambs, growth

Three experiments involving 11 600 male broiler chickens sought to determine if the pelleting process affects the dietary micronutrient, fat and protein components to increase the incidence of sudden death syndrome. Processed dietary micronutrient and fat components were not significantly associated with an increase in sudden death syndrome among broiler chickens. In one of the experiments, the incidence of sudden death syndrome was reduced (P < 0.01) when the dietary protein supplements (soybean meal, canola meal and fishmeal) bypassed the pelleting process.

Oil-extracted meals from Westar (WCM) and triazine-tolerant (TCM) canola seed (B. napus) were fed at levels of 0, 10, 20 and 30% of the diet to seven barrows of 35 kg initial weight in digestibility trials conducted in four successive replicates. The digestion coefficients for energy were 66 and 69%, respectively, and for crude protein were 76 and 80%. The corresponding digestible energy values were 13.31 and 13.96 MJ kg−1, respectively, and the digestible crude protein values were 32.6 and 37.5%, indicating that the WCM sample was inferior to the TCM sample. The meals were compared in a feeding trial involving 80 pigs housed in groups of four but fed individually from 23 to 100 kg liveweight. Five protein supplement combinations (soybean meal alone (control) and WCM or TCM replacing 50 or 100% of the soy protein) were tested in barley:wheat (2:1) diets with or without supplemental lysine (0.15–0.18%) and fed in meal or pellet form to male and female pigs. There were no significant differences among meals tested in average daily gain in either the growing (0.74 kg) or the finishing period (0.81 kg) but efficiency of feed utilization during the grower period (23–57 kg) was better with soybean meal diets than with the CM diets. Lysine supplementation improved daily gains from 0.70 to 0.77 kg in the grower period and from 0.79 to 0.83 kg in the finisher period. The corresponding improvements in feed:gain ratios were from 2.89 to 2.66 and from 3.75 to 3.62. Pelleting improved daily gain from 0.75 to 0.80 kg and feed:gain from 3.39 to 3.18, over the 23- to 100-kg weight range. Key words: Canola meal, Westar, triazine-tolerant, pigs, feeding trial

Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC) of dry matter (ADCDM), crude protein (ADCCP), gross energy (ADCGE) and amino acids (ADCAA) of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g). The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT), using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg-1 crude protein and 3,692 Kcal kg-1 gross energy. Additionally 1.0 g kg-1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%), followed by the other ingredients. There was no significant difference between the soybean meal (95.16%), fish meal (92.97%) and the corn meal (91.90%) for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%). The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients.

The biological availability of biotin in canola meal (CM), cereal grain, cereal grain plus CM, and soybean meal (SBM) was estimated, using 140 pigs in the 10- to 20-kg weight range. In exp. I, pigs (six/treatment) were individually housed and fed a basal casein-cornstarch diet with 0, 50, 100, 150, 200 or 250 μg d-biotin kg−1 to generate data for a dose-response curve based on plasma biotin concentration. Other pigs were fed CM, SBM or soyprotein isolate (SPI) included in the diet. In exp. II, pigs were housed in pairs and four pairs were fed diets based on cereal grain or cereal grain plus CM. Results (exp. I) showed a higher correlation between daily biotin intake and plasma biotin (r = 0.835, P < 0.01) than on growth rate (r = 0.627, P < 0.05). The regression for plasma biotin (Y) on biotin intake (X) computed from the linear portion of the curve (i.e., 0-200 μg added biotin kg−1) was[Formula: see text]Biotin bioavailability in various feedstuffs was highest for corn (101.2%), followed by SBM (85.5%), CM (70.9%), and wheat (33.3%), triticale (25.9%), sorghum (25.1%) and barley (24.0%).

AbstractFour diets, barley/proprietary protein concentrate (B/PC), barley/maize gluten (B/MG), barley/rapeseed meal (B/RSM) and wheat/'rapeseed meal (W/RSM) were formulated to contain 165 g crude protein and 13·0 MJ metabolizable energy per kg dry matter. In experiment 1, all four diets were offered ad libitum to Charolais × Friesian bulls from 187 kg live weight to slaughter at about 488 kg live weight. In experiment 2, the B/PC and B/RSM were offered ad libitum to Charolais × (Hereford × Friesian) bulls from 222 kg live weight to slaughter at about 491 kg live weight. There were no significant differences between treatments in daily live-weight gain, percentage fat and lean in the live animal, slaughter weight or days on experiment in either experiment. In experiment 1, the carcasses from bulls given B/PC were 14 kg heavier than carcasses from bulls given W/RSM (P<0·05), but only 10 and 7 kg heavier than from bulls given B/MG and B/RSM respectively (P<0·05). The killing-out proportion of bulls given B/PC was significantly greater (P<0·05) than bulls given B/RSM. In experiment 2, carcass weights were similar but the killing-out proportion of bulls given B/PC were again greater (P < 0·001). It is concluded that B/MG and B/RSM were as effective as B/PC as finishing diets and that wheat can be successfully substituted for barley, when offered with rapeseed meal.

Three experiments were conducted with dairy cows to determine the effects of rapeseed meal and/or urea upon ad libitum consumption of grain rations. In corn, corn–barley and barley-oat basal rations, replacement of soybean meal (10%) by rapeseed meal (12–13%) resulted in a decrease in grain intake. Substitution of 1.4% or 1.6% urea (22% or 19% of the total crude protein intake) for soybean meal also resulted in decreased ad libitum grain consumption. A combination of rapeseed meal (6%) and urea (08%) was comparable to 12% rapeseed meal in effect upon consumption but less marked than 1.6% urea. No rations containing rapeseed meal had significant effects upon milk composition or production. In one experiment, a significant decrease in production occurred through including 1.6% urea in the grain ration.

Twenty barrow and twenty gilt Berkshire x Large White pigs were fed barley based diets containing protein supplements of either 13 per cent soybean meal, 9 per cent fishmeal, 14.5 per cent safflower meal plus 0.2 per cent I-lysine mono hydrochloride plus 0.1 per cent methionine or 14.5 per cent safflower meal plus 4.5 per cent fishmeal from 46.4 to 87.0 kg liveweight. All diets were fed individually at a restricted feeding scale. The safflower meal diets were also fed ad libitum. Barrows and gilts fed ad libitum recorded a 65 and 27 per cent improvement respectively in average daily gain and had slightly fatter carcases than those fed comparable diets restrictively. Feed conversion ratio was not significantly affected by level of feeding. Growth and carcase attributes of pigs fed diets restrictively were similar apart from the feed conversion ratio of pigs fed the amino acid supplemented safflower meal diet, which was inferior (P < 0.05) to those fed the soybean meal supplemented diets. Barrows grew faster and produced fatter carcases than gilts, A significant sex x diet interaction occurred from which it was concluded that gilts, but not barrows, could be fed ad libitum without detriment to the quality of the carcase.
