This study investigated the effects of sorghum ensiled as whole grains with different dry matter concentrations on the apparent total tract digestibility (ATTD) of energy, crude nutrients and minerals in growing pigs. Whole grain sorghum batches with varying dry matter (DM) concentrations of 701 (S1), 738 (S2) and 809 g kg−1 (S3) due to different dates of harvest from the same arable plot, were stored in air-tight kegs (6 L) for 6 months to ensure complete fermentation. Subsequently, 9 crossbred barrows (34.6 ± 1.8 kg; (Duroc x Landrace) × Piétrain)) were used in a 3 × 3 Latin square feeding experiment. Diets were based on the respective sorghum grain silage and were supplemented with additional amino acids, minerals and vitamins to meet or exceed published feeding recommendations for growing pigs. The ATTD of gross energy, dry matter, organic matter, nitrogen-free extracts, and crude ash were higher in S1 compared to S3 treatments (p ≤ 0.05), while S2 was intermediate. Pigs fed S1 showed significantly higher ATTD of phosphorus (P) compared to all other groups while ATTD of calcium was unaffected irrespective of the feeding regime. In conclusion, growing pigs used whole grain sorghum fermented with a DM concentration of 701 g kg−1 (S1) most efficiently. In particular, the addition of inorganic P could have been reduced by 0.39 g kg−1 DM when using this silage compared to the variant with the highest DM value (809 g kg−1).

Buckwheat (Fagopyrum esculentum) was evaluated alone or with 25, 50, 75 or 100% replacement by wheat (W) or barley (B) in 16% protein diets fed to 72 crossbred pigs from 20 to 60 kg liveweight. Pigs were randomly alloted two per pen, within sex, and housed in confinement on partially slatted concrete floors. Daily feed consumption (1.89–2.27 kg/day), average daily gain (0.66–0.72 kg/day) and feed/gain (2.79–3.18) did not differ significantly (P < 0.05) between treatments. At 50% replacement of the buckwheat (BW) more feed (P < 0.05) was consumed (2.22 kg/day) than at 25 or 100% replacement levels (1.99 and 1.92 kg/day, respectively). More DE was consumed per kilogram of gain (DE/gain) (P < 0.05) by wheat-fed pigs than by barley-fed pigs (40.0 vs. 38.2 MJ DE/kg, respectively). The 50% substitution of either grain (42.1 MJ/kg) resulted in more DE/gain (P < 0.05) than observed on the BW only diet (37.1 MJ/kg). Two 4 × 4 latin square designs, with eight pigs initially weighing 40 kg, were used for determination of digestibility of dry matter (DM), crude protein (CP) and gross energy (GE) in BW, W or B individually and in blends of BW and either W or B. Coefficients of digestibility for CP were 72.7%, 81.6% and 65.5% and for GE were 65.4%, 80.2% and 71.1% in BW, W and B, respectively. Blends of BW and W had digestibility coefficients for DM, CP and GE between the values determined for the grains individually but those determined for mixtures of BW and B were lower than expected based on coefficients determined for the grains individually. Buckwheat used contained 12% CP, 0.68% lysine, 12.3% acid detergent fiber on as fed basis and 9.6% digestible protein and 11.98 MJ of DE per kilogram dry matter.

Effect Of Feeding

Abstract Fermentation of cereal grains may degrade myo-inositol hexakisphosphate (InsP6) thereby increasing nutrient digestibility. Effects of chemical acidification or fermentation with Limosilactobacillus (Lm.) reuteri TMW 1.656 with or without phytase on nutrient digestibility of diets composed of high β-glucan hull-less barley grain were assessed in growing pigs. Four mash diets contained 50% barley grain: 1) unfermented barley (Control); 2) chemically-acidified barley (ACD) with lactic and acidic acid [0.02 L/kg barley grain, 4:1 (v/v)]; 3) barley fermented with Lm. reuteri (Fermented without phytase); and 4) barley fermented with Lm. reuteri and phytase (Fermented with phytase; 500 FYT/kg barley grain). The 4 diets were fed to 8 ileal-cannulated barrows (initial BW, 17.4 kg) for four 11-d periods in a double 4 × 4 Latin square. The InsP6 content of barley grain in Control, ACD, Fermented without phytase, or Fermented with phytase was 1.12, 0.59, 0.52% dry matter, or not detectable, respectively. Diet apparent total tract digestibility (ATTD) of crude protein (CP), Ca, gross energy and digestible energy and predicted net energy values were greater (P &lt; 0.05) for ACD and Fermented without phytase than Control. Diet apparent ileal digestibility (AID) of Ca and standardized total tract digestibility (STTD) of P tended to be greater (P &lt; 0.10) for Fermented without phytase than Control. Diet STTD of P, AID and ATTD of Ca was greater (P &lt; 0.05) for Fermented with phytase than Fermented without phytase. Acidification or fermentation with/without phytase did not affect diet standardized ileal digestibility of CP and AA. In conclusion, fermentation with phytase completely degraded InsP6 in barley grain and maximized P and Ca digestibility, thereby reducing the need to provide inorganic P to meet P requirements of growing pigs.

Faba Beans

Four castrated pigs, each fitted with a re-entrant cannula in the terminal ileum, were used to study digestion in the small intestine. A nitrogen-free diet was used for the estimation of metabolic nitrogen and amino acids. Faba beans, as the sole source of dietary protein, were used raw or after autoclaving for 30 or 60 min. The four diets were fed to the pigs in a 4 × 4 latin square experiment. The pigs were fed each diet for 6 days prior to a 24-hr collection of total ileal contents. Autoclaving of faba beans had no significant effect on digestibility of dry matter, gross energy, nitrogen and individual amino acids except arginine, which was significantly increased. The intestinal uptake of arginine was the highest and of cystine the lowest in all faba bean diets. It was concluded that autoclaving faba beans had no beneficial effect on the digestion of nutrients in the small intestine of the pig.

SUMMARY1. A split-plot design was used to study apparent digestibility of dry matter, gross energy and nitrogen of a whole grain wheat diet and processed (hammermilled, rolled or hammermilled and then steam-pelleted) wheat diets by eight small (33·9 ± 0·1 kg) and eight large (70±1·7 kg) pigs. Metabolizable energy and nitrogen retention were also studied with the small pigs.2. The processed wheat diets were superior to the whole grain wheat diet in all the parameters measured.3. There were no significant differences between the performance of pigs given the differently processed wheat diets.4. Apparent digestibility of dietary components particularly in the whole wheat diet was significantly higher when diets were given to small pigs than when given to large pigs.

SUMMARYA 6 x 6 Latin Square balance experiment was carried out using six Friesian steers, each of which initially weighed about 304 kg. The six treatments studied were an all-hay diet and five other diets containing 20,40,60,80 and 100 % of rolled barley fortified with mineral and vitamin supplements, accompanied by correspondingly reduced proportions of hay. Each diet was fed at an estimated maintenance level of feeding.The progressive increase in the proportion of concentrate gave a significantly linear increase (P < 0·001) in both digestible and calculated metabolizable energy. The actual increase in digestible energy was from 2·62Mcal/kg dry matter (59·3% of the gross energy) on the all-hay treatment to 3·42 Mcal/kg dry matter (79·5% of the gross energy) on the all-concentrate treatment. Use of the determined digestible energy values for the all-hay and fortified barley diets to calculate the digestible energy of the four mixed diets gave results in reasonably good agreement with the determined values, the maximum difference being 0·12 Mcal/kg dry matter, which represented 3·83 % of the determined value. The losses of energy in the urine expressed as percentages of the gross energy of the diets showed a small but significantly linear decrease (P < 0·01) with increase in proportion of barley in the diet. The molar proportions of steamvolatile acids in samples of rumen fluid taken from two animals on each treatment indicated that increase in the proportion of concentrate was associated with tendencies for increase in acetic acid, decrease in propionic acid and little change in butyric acid. The mean digestibility of the organic matter was 62·6 % on the all-hay treatment and 81·8 % on the all concentrate treatment. The progressive increase in the proportion of concentrate gave a significantly linear increase (P < 0·001) in digestibility of the organic matter. Although intakes of nitrogen decreased with increase in the proportion of concentrate due to a decrease in the amount of dry matter fed, the weights of nitrogen retained were well maintained and when expressed as percentages of intake showed a significantly linear increase (P < 0·01).

Abstract Two experiments were conducted to investigate the effects of phytase source and feed pelleting on digestibility of dry matter (DM), crude protein, organic matter (OM), and phosphorus (P) with different doses of phytase in pigs. In Exp. 1, ten barrows (31.4 ± 3.5 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 6 Latin square design with 5 diets and 6 periods. In Exp. 2, ten barrows (28.2 ± 3.2 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 5 Latin square design with 5 diets and 5 periods. Each period lasted 10 d consisted of a 5-d adaptation and a 5-d collection periods and the marker to marker method was used for fecal collection. In both experiments, a basal diet was prepared based on corn and soybean meal without phytase or inorganic P. Four additional diets were prepared in a 2 × 2 factorial treatment arrangement with 2 phytase sources (Buttiauxella spp. or Escherichia coli) and 2 feed forms (mash or pellet). Both experiments employed the same treatments but had different supplemental phytase doses (500 and 1,500 FTU/kg in Exp. 1 and 2, respectively). In Exp. 1, supplemental phytase increased standardized total tract digestibility of P (66.1 vs. 51.7%; P &lt; 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM, crude protein, and OM (P &lt; 0.001). In Exp. 2, supplemental phytase increased standardized total tract digestibility of P (72.8 vs. 44.8%; P &lt; 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM and OM (P &lt; 0.001). Taken together, supplemental phytase at 500 and 1,500 FTU/kg increases P digestibility regardless of phytase source or feed pelleting.

The suitability of feeding whole grain cereal (maize or sorghum) in diets was investigated in three individual-feeding trials conducted under simulated tropical conditions. In each trial rabbits were allocated to one of four diets (Table 1); complete pelleted diet based on maize (PM), whole maize plus pelleted concentrate supplement (WM), complete pelleted diet based on sorghum (PS) or whole sorghum plus pelleted concentrate supplement (WS). In Trial 1 whole maise and whole sorghum contained 84 and 103 g crude protein/kg dry matter (DM) respectively. In Trials 3 and 3 whole maize and whole sorghum contained 60 and 98 g crude protein/kg DM and 18.87 and 18.67 MJ gross energy/kg DM respectively.

SUMMARYTwo growth and two metabolism experiments were made in which a low gluoosinate rapeseed meal (var. Tower; TRSM) was compared with soya-bean meal (SBM) as the sole protein-rich material in simple diets containing barley and a vitamin and mineral supplement only.In the first growth experiment 108 pigs were fed individually and restrictedly SBM and TRSM diets so that digestible energy (DE) and crude-protein intakes were similar. The DE used to promote a unit of growth or a unit of carcass weight was significantly less for the SBM, than for the TRSM, diet. In the second experiment 48 pigs were given, in groups of four, diets similar to those in Expt 1. There were no significant differences in growth rate or in serum thyroxine concentrations, but a significantly higher degree of thyroid hypertrophy was induced in pigs given the TRSM diet.The two metabolism experiments compared the same diets used in the first growth experiment. Apparent digestibility of dry matter, nitrogen and gross energy, and retention of nitrogen relative to intake, were significantly greater for the SBM diet than for the two RSM diets. The addition of synthetic lysine to the TRSM diet significantly improved the apparent digestibility and retention of nitrogen. Pooled DE values (MJ/kg dry matter) calculated for SBM, TRSM and barley were 13·72 (S.E. 0·318), 13·97 (S.E. 0·211) and 14·01 (S.E. 0·080) respectively.

ABSTRACT: This study aimed to determine the apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values as well as the metabolizability coefficients of dry matter, protein, and ether extract of corn, pearl millet, and sorghum in different particle sizes for slow-growing broilers. Two experiments were carried out involving 280 chicks of the Label Rouge® Naked Neck broiler line, with 140 chicks allotted to each experiment in a completely randomized design. Treatments consisted of a reference diet and a test diet (60% reference diet + 40% feedstuff). The feedstuffs were tested and particle size (expressed as geometric mean diameter [GMD, μm] and geometric standard deviation [GSD], respectively) results were 816 and 1.73 for coarsely ground corn, 794 and 1.75 for finely ground corn, 1.517 and 1.92 for pearl millet grain, 760 and 1.63 for finely ground pearl millet (Experiment 1); and 1,866 and 1.86 for whole grain sorghum, 919 and 1.62 for coarsely ground sorghum, and 878 and 1.72 for finely ground sorghum (Experiment 2). A metabolism trial was conducted by using the total excreta collection method to obtain the AME and AMEn values as well as the metabolizability coefficients of dry matter, protein, and ether extract. The energy metabolization coefficient did not differ (P > 0.05) between the grains in the different tested particle sizes. However, there was an improvement in the metabolizability coefficients of dry matter, nitrogen, and ether extract as the particle size of corn was increased. In conclusion, larger grain particle sizes improve the metabolizability of nutrients and energy for slow-growing broilers. Whole-grain sorghum has limited nutritional utilization for slow-growing birds up to 21 days of age.
