Two experiments were carried out to evaluate the nutritive value for growing cattle of by-products from a new process for integrated starch-ethanol production from barley. Experiment 1 was a 4 x 4 Latin Square, in which the effects of barley protein (375 g crude protein (CP)/kg dry matter (DM)) on digestibility and N retention were examined in four male cattle (initial live weight(LW) 147 kg). The control diet (C) consisted of hay and rolled barley (1 : 1). In isonitrogenous experimental diets, soybean meal (S), a mixture of soybean meal and barley protein (SB) or barley protein (B) was substituted for barley to increase the dietary CP content from 125 to 150 g/kg DM. Replacement of barley with protein supplements increased (P

Based on the potential benefits to human health, there is interest in developing sustainable nutritional strategies to enhance the concentration of long-chainn-3 fatty acids in ruminant-derived foods. Four Aberdeen Angus steers fitted with rumen and duodenal cannulae were used in a 4 × 4 Latin square experiment with 21 d experimental periods to examine the potential of fish oil (FO) in the diet to enhance the supply of 20 : 5n-3 and 22 : 6n-3 available for absorption in growing cattle. Treatments consisted of total mixed rations based on maize silage fed at a rate of 85 g DM/kg live weight0·75/d containing 0, 8, 16 and 24 g FO/kg diet DM. Supplements of FO reduced linearly (P < 0·01) DM intake and shifted (P < 0·01) rumen fermentation towards propionate at the expense of acetate and butyrate. FO in the diet enhanced linearly (P < 0·05) the flow oftrans-16 : 1,trans-18 : 1,trans-18 : 2, 20 : 5n-3 and 22 : 6n-3, and decreased linearly (P < 0·05) 18 : 0 and 18 : 3n-3 at the duodenum. Increases in the flow oftrans-18 : 1 were isomer dependent and were determined primarily by higher amounts oftrans-11 reaching the duodenum. In conclusion, FO alters ruminal lipid metabolism of growing cattle in a dose-dependent manner consistent with an inhibition of ruminal biohydrogenation, and enhances the amount of long-chainn-3 fatty acids at the duodenum, but the increases are marginal due to extensive biohydrogenation in the rumen.

The physiochemical properties and digestible, metabolizable, and predicted net energy contents in high-protein dried distillers’ grain (HiPro) were determined to assess the nutritive value for growing pigs. Twelve Yorkshire × Landrace barrows (initial body weight 25 ± 0.5 kg) were used in a partially replicated Latin square design over three periods (n = 7 or 8) and assigned to one of five experimental diets. In each period, pigs were adapted to diets for 7 d, followed by 5 d of total urine collection and fecal grab sampling. The experimental diets included a corn- and soybean-meal-based diet (CON) or diets containing dried distillers’ grains with solubles (DDGS) or HiPro to partially replace corn and soybean meal, without or with (i.e., DDGS+ and Hipro+) a multi-carbohydrase enzyme blend (0.05% inclusion). The HiPro ingredient contained half as much starch (2.6% vs. 5.2%; DM-basis), 20% more protein (32.5% vs. 27.1%), and had 14% greater water binding capacity versus DDGS. The digestible, metabolizable, and predicted net energy contents of the HiPro co-product were greater than DDGS for growing pigs (P < 0.05), but fibre-degrading enzymes were ineffective at improving energy values. The greater (available) energy and protein contents of HiPro make it a promising feed ingredient for inclusion in swine diets.

Two experiments were conducted to evaluate rapeseed meal (RSM) produced from seed of Brassica campestris L. ’Candle’ in comparison with B. napus L. ’Tower’, soybean meal and fababeans (Vicia faba) as protein supplements for growing swine. In experiment 1 Candle RSM (5, 10 or 15%) was substituted for soybean meal or fababeans in barley- and wheat-based diets for 120 pigs from 23 to 88 kg liveweight. The effects of supplementary iodine (0.14 mg I/kg diet) and amino acids (0.15% lysine and 0.05% methionine) on the nutritive value of Candle RSM were also studied. The results of experiment 1 indicated that daily feed intake and carcass value index were not significantly (P > 0.05) affected by diets. The growth and feed utilization responses of pigs fed diets which contained soybean meal and fababeans as the sole source of supplementary protein were similar and the replacement of these protein supplements with Candle RSM, unless supplemented with amino acids, resulted in a reduction in rate of growth and efficiency of feed utilization. Gains adjusted by regression for feed intake variations showed benefit from lysine. Diets containing 15 % of either Candle or Tower RSM, plus lysine, were utilized about 95% as efficiently as soybean meal diets. Supplementation with iodine produced no significant response. The digestibility coefficients of the protein and energy of Candle RSM and soybean meal were determined in experiment 2. The apparent digestibility of protein in Candle RSM was 81% and energy digestibility was 71%. The digestible energy content was 14.12 MJ/kg (3370 kcal/kg), dry matter basis.

Four rumen-fistulated sheep, 62 kg average body weight (BW), were assigned four pelleted diets containing 0 (control), 15, 30 and 45% steam-processed aspen (SPA) in a 4 × 4 Latin square design. All diets were formulated to be isonitrogenous to the control diet which contained 45% ground alfalfa hay as a roughage source. Intake of dry matter (DM), crude protein (CP), crude fiber (CF) and gross energy (GE) per kg BW0.75 were not affected (P > 0.05) by addition of SPA to pelleted sheep diets. However, digestible energy (DE) consumption apparently decreased with SPA diets. Apparent digestibilities of DM and GE significantly (P < 0.05) decreased for the SPA diets; however, CP and CF digestibility coefficients and N retention were not different (P > 0.05) among the four treatments. Ruminal pH for all treatments fell rapidly within 1 h post feeding and remained low to 12 h, whereas ammonia (NH3) levels were significantly (P < 0.05) elevated for all aspen-fed animals, from 1 h through 12 h post feeding. Total VFA concentrations and molar concentrations of acetic, propionic and butyric acids in ruminal fluid were comparatively lower for sheep fed the 45% SPA diet versus those receiving the other treatments. Blood serum glucose concentration was significantly (P < 0.05) depressed when 45% SPA was fed to mature sheep.

The objective of this study was to evaluate the total replacement of soybean meal (SM) with extruded semi-whole soybean (ESWS) and its effects on feed digestibility, growth performance, plasma urea concentration (PUC) and economic feasibility. In Experiment I, a digestibility assay was undertaken using 12 crossbred pigs with an initial average body weight (IABW) of 18.85 ± 0.69 kg, distributed in a completely randomized design (CRD), with two treatments (reference diet and replacement of 30% of the reference diet by ESWS), six replicates and one pig per experimental unit. Experiment II involved 64 crossbred piglets, entire males, with an IABW of 7.46 ± 0.55 kg, distributed in a CRD, with two treatments (a control diet containing SM and another in which ESWS replaced SM), eight replicates and four animals per experimental unit. The digestible contents of dry matter, crude protein and gross energy of ESWS were 91.26%, 42.21% and 4,629 kcal kg -1, and the digestibility coefficients were 92.33%, 96.49% and 91.21%, respectively. Experiment II data indicated an effect on the feed conversion (FC) in the total period, in which pigs fed SM presented better FC. The diets affected the PUC in the pre-starter II phase and the total period, with pigs fed SM showing higher PUC. The cost of feed per kilogram of live weight gain increased in the starter phase. ESWS does not change the DWG and ADFI of piglets but worsens both the FC in the total period and economic results.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

The bioavailability of phosphorous, and blood serum and rumen liquor P level was studied in indigenous growing cattle by feeding bone meal and Triple Super Phosphate (TSP) with control diet. Nine indigenous growing cattle (live weight of 164 ± 21 kg) were randomly assigned in a Completely Randomized Design (CRD) to three dietary treatments, consisted of a basal diet (T0) of 0.16% P and experimental diets supplemented with bone meal (T1) and triple super phosphate (T2) to provide P level of 0.44%. All diets were formulated to be iso-nitrogenous and iso-caloric. Three cannulated animals were used for rumen liquor P level study by feeding three diets. Apparent absorption and balance of P were significantly (P<0.01) higher in T1 and T2 diets than that of diet T0, but true absorption did not differ significantly (P>0.05). Bioavailability of P of control diet (37.41%), bone meal (81.45%) and triple super phosphate (80.49%) were significantly differed (P<0.01). Rumen liquor and blood serum P level differed significantly (P<0.01). Supplementation of bone meal and triple super phosphate results in high blood serum P (P>0.05) with no difference between bone meal and triple super phosphate. The results suggested that the bioavailability of P from bone meal and TSP was high and dietary supplementation of P with bone meal and TSP improved P retention and blood serum P level.

1. The effect of harvesting date of perennial ryegrass (Lolium perenne) on the nutritive value of the resultant silage and the effect of substitution of late-cut silage with barley was examined in growing cattle. The diets comprised early-cut (H) and late-cut (L) silage offered alone or with 280 (LCI) or 560 (LC2) g rolled barley/kg total dry matter (DM) substituted for late-cut silage.2. Both silages were prepared with the addition of formic acid (850 g/l; 2.4 litres/t fresh weight) to a partially wilted crop, and were judged to be well fermented (pH 3.9, 3.8) with lactic acid contents of 108 and 73 g/kg DM, total nitrogen contents of 24.6 and 18.4 g/kg DM and ammonia-N contents of 121 and 124 g/kg total N (values for early- and late-cut silages respectively).3. Two experiments were conducted to measure duodenal non-NH3-N (NAN) supply in relation to N intake on the four diets (feeding level 18 g DM/kg live weight (LW)) and to examine the partition of the metabolizable energy (ME) supply from the four diets using open-circuit indirect calorimetry (three feeding levels, 14, 17 and 20 g DM/kg LW). The experiments were undertaken with eight and nine Friesian male castrates respectively with a mean starting weight of 300 kg and age 12 months. The animals used in Expt 1 had been previously fitted with cannulas into the dorsal rumen and the proximal duodenum.4. NAN supply was significantly higher on diet H than all other diets which were similar irrespective of the level of barley inclusion. Mean ME contents (MJ/kg DM) of the two silages differed markedly (H 11.9, L 9.7) and barley addition (LCI and LC2) restored values to 10.7 and 11.1 MJ/kg DM respectively. Estimated NAN absorption in relation to energy supply was significantly higher for diet H (1.47 g/MJ ME) than for all other diets (mean 1.25 g/MJ ME).5. Partition of ME supply using conventional linear analysis indicated dietary differences with respect to estimated ME for maintenance (L > H, LCI and LC2) and efficiency of utilization of ME supplied above maintenance (L > H, LCI and LC2), but difficulties in biological interpretation of these findings led to the use of exponential curve analysis. This provided an improved description of the findings, and whilst dietary differences were apparent, none were statistically significant. It was concluded that a single exponential equation could be used satisfactorily to describe all values.6. The consequence of these findings in relation to the carcass retentions of energy. fat and protein reported by Thomas et al. (1988) is discussed and possible reasons for the discrepancies in energy retention measured by comparative slaughter balance and open-circuit indirect calorimetry are considered.

Forage Harvester

Corn stover stacks were harvested and a portion of these were treated with anhydrous ammonia at a level of 3% of dry matter (DM) and left covered with plastic for at least 30 days during the fall of 1977. In the spring, both treated and untreated corn were chopped through a forage harvester. A portion of each was then ground through a 1.3-cm screen. Treatments were: untreated chopped, untreated ground, ammoniated chopped, ammoniated ground. Treatments were evaluated with eight Hereford-Angus yearling steers in a double 4 × 4 latin square design. In addition to the stover, rations contained 10% molasses, 6% soybean meal, and 2.3% mineral mix. Urea was added to the untreated rations at the level of 1.6% to make rations isonitrogenous. Steers were injected with vitamins A, D and E at 90-day intervals. With both control and ammoniated rations, grinding increased (P < 0.001) intake on a body weight raised to the 0.75 power basis (MBW) of DM, digestible energy (DE) and digestible DM by 47%, 39%) and 39%), respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) intake of digestible DM and DE and increased (P < 0.01) intake of DM all on a MBW basis by 22%, 31% and 12%), respectively. However, grinding decreased digestibilities of DM and neutral detergent fibre (NDF) (P < 0.001) and of organic matter (OM) (P < 0.01) by 5%, 10% and 5%, respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) digestibility of DM, OM, and NDF by 9%, 9% and 14%, respectively. Ammoniation plus grinding increased (P < 0.01) intake (MBW) of DM, digestible DM and DE by 64%), 71% and 85%), respectively, over untreated chopped rations. Grinding increased (P < 0.01) rumen acetate 0.5 h preprandially but did not significantly affect other rumen parameters measured preprandially or 2 h postprandially. Ammoniation increased (P < 0.01) rumen propionate 0.5 h preprandially but did not significantly affect the remaining rumen parameters. Before versus after feeding levels of rumen metabolites did not differ except for an increase (P < 0.01) in ammonia-N and total VFA postprandially. No significant treatment interactions were present.

The objectives of the present study were to evaluate the nutritive value of expeller linseed meal (ELM) and solvent linseed meal (SLM) as protein supplements for lactating dairy cows utilizing analytical and in situ procedures, and determine the in vivo nutritive value of the most promising linseed meal in diets containing either barley or corn-based concentrate. Canola meal (CM) and soybean meal (SBM) were included in the evaluative stage for comparative purposes. Linseed meals contained 37.8 and 35.4% crude protein (CP); 22.6 and 25.9% neutral detergent fibre (NDF); and 12.9 and 7.1% crude fat for ELM and SLM, respectively. Rate and extent of dry matter, NDF, and CP digestion, as determined by the rumen in situ technique, indicated that ruminal digestibility of SLM was similar to that observed for CM, but ruminal escape of ELM protein was higher than for CM. The proportion of ruminal escape protein was similar for SLM, CM and SBM. Total tract CP digestibilities of SLM and CM were similar to and lower than those observed for ELM and SBM. Soybean meal had the highest total tract CP digestibility. Based on results of the analytical and in situ procedures, SLM was selected for evaluation in the in vivo experiment. Results indicated that SLM did not have any deleterious effect on digestion of other components of the diet, and parameters of rumen fermentation indicated similar digestion patterns for cows fed SLM and CM. Overall, results indicate that SLM has potential as a replacement for CM or SBM in diets of dairy cattle. It was also concluded that replacement of barley with corn does not influence the nutritive value of SLM for dairy cows. Key words: Linseed meal, canola meal, dairy cattle
