Abstract The objective of this study was to examine the conservation process and feed value of total mixed ration (TMR) silages. In exp. 1, we evaluated the fermentation pattern and aerobic stability of TMR silages containing different protein and lipid supplementations. In exp. 2, we compared the performance of finishing beef heifers fed those TMR silages. In both experiments, treatments were as follows: ensiled TMR with urea (U); ensiled TMR without a protein supplement at ensiling, but soybean meal supplemented at feeding to balance diet crude protein (CP) in exp. 2 (SMnf; where the acronym nf indicates nonfermented); ensiled TMR with soybean meal (SM); and ensiled TMR with rolled soybean grain (SG). Thirty-two Nellore heifers (313 ± 8.8 kg shrunk body weight [SBW]) were blocked by initial SBW, housed in individual pens, and enrolled in exp. 2 for 82 d. In exp. 1, treatment without a protein supplement (SMnf) had a lower content of CP, soluble CP, NH3-N, pH, and Clostridium count compared with U (P ≤ 0.03). Lactic acid concentrations tended to be reduced for SMnf compared with U (P = 0.09). Ethanol concentration was reduced in SG compared with SM (P < 0.01). 1,2-Propanediol concentration was increased in SMnf compared with U (P < 0.01), reduced in SM compared with SMnf (P = 0.02), and increased in SG compared with SM (P = 0.02). Dry matter (DM) loss during fermentation was low and similar among treatments (~3.7%). All silages remained stable during 10 d of aerobic exposure after feed out. Considering fermentation traits, such as pH (≤4.72), NH3-N (<10% of N, except for U treatment), butyric acid (<0.05 % DM), and DM losses (<3.70% DM), all silages can be considered well conserved. In exp. 2, diets were isonitrogenous because soybean meal was added to SMnf before feeding. Compared with SM, cattle fed SG made more meals per day (P = 0.04) and tended to have a decreased intermeal interval (P = 0.09). DM intake, average daily gain, final SBW, hot carcass weight, Biceps femoris fat thickness, and serum levels of triglycerides and cholesterol were increased for SG compared with SM (P ≤ 0.05). In brief, TMR silages exhibited an adequate fermentation pattern and high aerobic stability. The supplementation of true protein did not improve animal performance, whereas the addition of soybean grain as a lipid source improved the performance of finishing cattle fed TMR silages.

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.

Western-Canadian grown sweet white lupin seed (LS), canola meal (CM) and soybean meal (SM) were compared in situ and in digestibility and feedlot experiments using Romanov × Suffolk lambs. Barley-based (75.5% as fed) diets were isonitrogenous (15.5% crude protein, CP) with LS, CM or SM as protein source. Sunflower hulls were substituted as necessary for protein supplement to ensure the diets were isonitrogenous. The LS used in this trial was relatively low in alkaloids (0.03%), as compared with other lupins, and high in manganese (2347 mg kg−1). In situ, the effective rumen degradability of protein of LS was higher than that of either CM or SM. Rates of DM and protein disappearance were also higher for LS than for CM and SM. Digestibilities of DM organic matter, energy and nitrogen were higher (P < 0.05) in LS than in CM or SM diets, but there were no differences (P > 0.05) among the supplements in digestibilities of starch or NDF. No differences (P > 0.05) were found in feed conversion or DM intake of the three diets. Average daily gain (ADG) of the lambs receiving LS did not differ (P > 0.05) from those of lambs on the other two diets, but lambs on CM had higher ADG (P < 0.05) than lambs on SM. We conclude that LS is comparable to SM and CM as a protein supplement for lambs, provided care is taken to avoid toxic levels of manganese and alkaloids.

Two experiments were conducted to evaluate the replacement value of canola meal (CM) for soybean meal (SBM) in isoenergetic isonitrogenous diets for young pigs between 6 and 20 kg liveweight. Diets utilized wheat, barley, oat groats and blended animal fat as energy sources and evaluated CM at levels from 0 to 100% replacement of SBM. Regression analyses of the results of both experiments indicated that for every 1% addition of CM in the diet, there was a corresponding decrease in average daily feed intake (ADF) and average daily gain (ADG) of 4 and 2 g, respectively. Digestibility coefficients of dry matter and nitrogen were not significantly affected by the level of CM in the diet. Key words: Starter pig, canola meal, soybean meal, protein supplement

Abstract Two experiments were conducted to determine the effects of increasing levels of soybean meal (SBM) replacing feed grade amino acids in corn or corn-dried distillers grains with solubles (DDGS)-based diets on growth performance of late finishing pigs. In both experiments, there were 22 to 27 pigs per pen and 14 pens per treatment. Average length of the experiments was 35 (Exp. 1) and 29 days (Exp. 2). Diets were balanced to contain 0.70% SID Lys and 2,667 or 2,610 kcal NE/kg for Exp. 1 and 2, respectively. Minimum amino acid ratios relative to Lys were: Ile, 55; Met&Cys, 60; Thr, 65; Trp, 19.5, and Val, 70. Dietary crude protein ranged from 10.1 to 15.2 for Exp. 1 and 13.6 to 19.4 for Exp. 2. The statistical model considered fixed effects of treatment, linear and quadratic contrasts, and random effect of block. In Exp.1, 1,793 pigs (L337×1050, PIC; initially 104.9 ± 1.4 kg) were fed corn-based diets and pens of pigs were assigned to 1 of 5 dietary treatments with increasing SBM from 5 to 20%. Overall, average daily gain (ADG) and gain-to-feed (G:F) increased (linear; P &lt; 0.05) as SBM increased with the greatest improvement observed as SBM increased from 5 to 8.75%, with little improvement thereafter. In Exp. 2, 1,827 pigs (L337×1050, PIC; initially 97.9 ± 1.1 kg) were used in a similar study as Exp. 1, but all diets contained 25% DDGS and SBM levels increased from 0 to 16%. Overall, G:F and final bodyweight of pigs marginally improved (linear and quadratic, respectively; P &lt; 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM. These results suggest that increasing SBM up to 8% at the expense of feed grade amino acids in corn or corn-DDGS-based diets improved ADG or G:F in late-finishing pigs.

The aim of this study was to evaluate the use of restricted grazing of an improved natural pasture as an alternative to conventional protein supplements for weaned lambs grazing natural pastures during summer–autumn. Two natural pastures that differed in dry matter allowances were used as basal diets. Sixty Corriedale lambs, 3 months old, were divided into 10 homogeneous groups. For each natural pasture, one group of lambs was randomly assigned to one of the following treatments (at 10 lambs/ha): continuous grazing (control); control + protein block (150 g/lamb. day); control + soybean meal (100 g/lamb. day); control + supplemental protein obtained from grazing for 3 h/day a natural pasture improved with Lotus uliginosus cv. Maku; or same as previous, except that grazing was allowed 1 in 3 days. Performance results (final bodyweight, average daily gain, and difference between initial and final body scores) were analysed as a completely randomised block design with subsampling. Lambs grazing 3 h/day or 1 in 3 days on improved pasture or supplemented with soybean meal showed better (P < 0.05) performance than non-supplemented lambs. Lambs consuming the protein block performed similarly (P > 0.05) to control lambs. The experiment demonstrated that feeding strategies using controlled grazing of natural pastures improved with lotus Maku or soybean meal supplementation are effective to achieve target growth rates of weaned lambs grazing natural pastures in summer–autumn.

Two experiments were conducted to determine the relationship between corn particle size and soybean meal treatment on growth, diet digestibility, and nitrogen balance of growing steers. In the first experiment, 40 medium-frame beef steers (250 ± 11 kg) were fed individually for 140 d a diet based on grass silage offered for ad libitum consumption and supplemented with either 3.5 kg of DM d-1 of cracked corn (CC) or ground corn (GC) and with 450 g of DM d-1 of solvent extracted (SS) or lignosulfonate-treated soybean meal (Soypass™ SP). Dry matter intake was not affected by treatments and averaged 8.6 ± 0.3 kg d-1 (P > 0.10). Average daily gain was higher for animals receiving the ground corn than those fed cracked corn. Feed to gain ratio was not affected by treatments. There was an interaction between treatments for plasma urea-N concentration, with source of soybean meal having no effect with CC. When compared with SS, SP supplement reduced plasma urea-N when fed with GC. No effect of soybean meal and its interaction with corn processing was observed on growth performance. In the second experiment four additional steers were used in a 4 × 4 Latin square design to evaluate diet digestibility and nitrogen balance. There was an interaction between treatments for starch apparent digestibility and N retained, the values being respectively, 90, 86, 93, and 92% (SEM = 1.2; P < 0.01) and 36, 42, 44 and 41 g d-1 (SEM = 2.8; P < 0.03) for CCSS, CCSP, GCSS and GCSP, respectively. Altogether, the results indicate a slight advantage to reduce particle size of corn in growing steers fed grass silage. However, soybean meal treatment resulted in limited effects on growth and digestion. Key words: Rumen carbohydrate, undegradable protein, performance, steers

Abstract Three studies evaluated the effects of added dietary salt on growth performance of pigs weighing 7 to 10, 11 to 30, and 27 to 65 kg. In experiment 1, 325 pigs were used with 5 pigs per pen and 13 pens per treatment. Pigs were fed a diet (0.39% Na and 0.78% Cl) for 7 d after weaning, then randomly assigned to diets with either 0, 0.20, 0.40, 0.60, or 0.80% added salt for 14 d. All diets were corn-soybean meal-based with 10% dried whey. Calculated Na concentrations were 0.11, 0.19, 0.27, 0.35, and 0.43% and calculated Cl concentrations were 0.23, 0.35, 0.47, 0.59, and 0.70%, respectively. Increasing salt increased (linear, P &lt; 0.05) average daily gain (ADG) and gain to feed ratio (G:F). For ADG, the linear, quadratic polynomial (QP), and broken-line linear (BLL) models were competing with the breakpoint for the BLL at 0.59% salt. For G:F, the BLL reported a breakpoint at 0.33% while the QP indicated maximum G:F at 0.67% added salt. In experiment 2, 300 pigs were used in a 34-d trial with 5 pigs per pen and 12 pens per treatment. Pigs were weaned at 21 d of age and fed a phase 1 diet (0.50% Na and 0.67% Cl) for 11 d and then a phase 2 diet (0.35% Na and 0.59% Cl) for 14 d. Then pens of pigs were randomly assigned to corn-soybean meal-based diets containing 0.20, 0.35, 0.50, 0.65, or 0.80% added salt. Calculated dietary Na concentration were 0.10, 0.16, 0.22, 0.28, and 0.34% and calculated Cl concentrations were 0.23, 0.32, 0.41, 0.50, and 0.59%, respectively. Overall, ADG and G:F increased (quadratic, P &lt; 0.07) with increasing added salt. For ADG, the QP and BLL had similar fit with the breakpoint for BLL at 0.51% added salt. For G:F, the BLL model predicted a break point at 0.35% added salt. In experiment 3, 1,188 pigs were used in a 44-d study with 27 pigs per pen and 11 pens per treatment. Pens of pigs were randomly assigned to corn-soybean meal-based diets containing 0.10, 0.33, 0.55, or 0.75% added salt. Calculated dietary Na concentrations were 0.10, 0.19, 0.28, and 0.36% and calculated Cl concentrations were 0.23, 0.36, 0.49, and 0.61%, respectively. Overall, there was no evidence to indicate that added salt above 0.10% of the diet affected growth. In conclusion, the BLL models suggested to maximize ADG for 7 to 10 and 11 to 30 kg pigs was 0.59% (0.34% Na and 0.58% Cl) and 0.51% added salt (0.22% Na and 0.42% Cl), respectively. There was no evidence that growth of 27 to 65 kg pigs was improved beyond 0.10% added salt (0.11% Na and 0.26% Cl).

The study aimed to evaluate the effect of SOYXYL as one of the dietary protected protein supplement product in the rations on the reproduction performance of Simmental bulls. Twelve 5 years-old Simmental bulls were allotted to 4 treatment groups with 3 replications in each, i.e.: T0= control ration (elephant grass + 5 kg/head/day commercial concentrate), T1= control ration + 150 g protected protein supplement SOYXYL (3% of concentrate), T2 = control ration + 300 g SOYXYL (6% of concentrate) and T3= control ration + 450 g SOYXYL (9% of concentrate). The experiment lasted for 90 days. At the end of the experiment, semen and blood were collected and body weight gain was measured. The variables measured included sperm motility, sperm concentration, blood protein, blood urea and the concentration of testosterone. Results showed that SOYXYL supplementation, particularly at the levels of 3 and 6%, increased the total plasma protein of bulls. SOYXYL supplementation at 3% from concentrate resulted in increased plasma urea concentration. Feeding SOYXYL, particularly at the levels of 6 and 9%, increased the average daily gain of bulls as compared to control. Feeding 3% SOYXYL increased, but at the levels of 6 and 9% decreased the concentration of sperm of bulls. The concentration of testosterone was higher in the bulls received 3 and 6% SOYXYL in the rations. Dietary supplementation of SOYXYL increased the sperm motility of Simmental bulls. In conclusion, dietary supplementation of SOYXYL at the level of 3% increased plasma protein, testosterone, and sperm concentrations as well as sperm motility. However, supplementation of SOYXYL at 6 and 9% from rations decreased the concentrations of sperm and testosterone.

Abstract This study evaluated the effect of different sources of nitrogen [soybean meal (SM); cottonseed meal (CM); cottonseed + urea (CU); and urea (U)] associated with spineless cactus on intake, digestibility, performance, carcass characteristics and meat quality of confined lambs. Forty male Santa Inês sheep, uncastrated, with initial body weight of 23.00 ± 1.66 kg were distributed in random blocks design and slaughtered after 58 days of confinement. Dry matter (DM) intake (1.16 ± 0.19 kg/day) did not differ (P > 0.05) between nitrogen sources, but the intake of crude protein (CP) and non-fibrous carbohydrates (NFC) was lower (P < 0.05) for sheep consuming CU. Sheep fed with diets containing U had lower digestibility of DM, CP and NFC (P < 0.05). The average daily gain (0.15 ± 0.04 kg/day) and the slaughter body weight (32.07 ± 2.86 kg) did not differ between nitrogen sources, but the cold carcass and loin weight was lower (P < 0.05) for sheep fed with U. The water retention capacity and meat protein content were greater (P < 0.05) for animals fed with SM. Soybean meal or cottonseed meal associated with spineless cactus-based diets for sheep meat production are recommended because it allows greater DM digestibilityand improves carcass characteristics and physicochemical composition of the meat.
