This study was conducted to determine the standardized ileal digestible amino acid (AA) and nitrogen-corrected apparent metabolizable energy (AMEn) contents of a high-protein sunflower meal (HiSFM) fed to broiler chicks. A total of 144 broiler chicks were randomly allotted to one of three dietary treatments with eight replicate cages of six birds. Birds were fed the experimental diets from day 14 to day 21 of age. The results showed that gross energy, crude protein, nonphytate phosphorus, lysine (Lys), methionine (Met), threonine (Thr), and total nonstarch polysaccharide contents of HiSFM were 4178 kcal kg−1, 48.7%, 0.86%, 1.59%, 0.75%, 1.45%, and 14.6%, as-fed basis, respectively. The standardized ileal digestible Lys, Met, and Thr of HiSFM were 12.6, 6.8, and 11.6 g kg−1(dry matter basis), respectively. In addition, the AMEncontent of HiSFM fed to broiler chicks was 1785 kcal kg−1. In conclusion, compared with literature values for sunflower meal, HiSFM had lower standardized ileal digestibility of indispensable AA and higher AMEncontent. The standardized ileal digestible AA and AMEnvalues of HiSFM obtained from the current study could be used when formulating poultry diets and to obtain predictable bird performance.

ABSTRACT Two experiments were carried out to determine the energy values and the true ileal digestibility of amino acids of nine toasted full-fat soybeans (FFSB), without or with the addition of monocomponent protease. In the first experiment, to determine the energy values, the method of excreta collection was used with 1120 broiler chicks at 14 days old, distributed in randomized blocks in a 10x2 factorial arrangement with nine full-fat soybeans (30% included) plus a control diet (70%) without or with the addition of protease, totaling 20 treatments with 8 replicates and 7 birds per cage. In the second experiment, 1120 broiler chickens from 24 to 28 days of age were distributed in randomized blocks in a 10x2 factor arrangement, with nine full-fat soybeans (40% included) + a protein free diet (60%), without or with the addition of protease, totaling 20 treatments with 8 replicates and 7 birds per cage. Ileal digesta collection was used to determine the true digestibility coefficients and the digestible amino acid content of full-fat soybean. The average values of nitrogen-corrected apparent metabolizable energy (AMEn) and their respective metabolization coefficients (CAMEn) were 3207 kcal/kg and 62.57%, respectively. The average values of digestibility coefficients of crude protein and essential and nonessential amino acids were 86.79, 87.90 and 84.34%, respectively. The inclusion of protease improved (P<0.05) all evaluated parameters. Therefore, its use is recommended in diets containing full-fat soybeans for broiler chickens.

Phosphorus (P) bioavailability, crude protein (CP), amino acid (AA) digestibility, and apparent metabolizable energy (AMEn) were determined in broiler chick diets, supplemented with one of two low-oil distiller´s dried grains with solubles (oil contents 6.54% and 5.35% for DDGS A and B, respectively). Diets were provided ad libitum in a mash form, from days 8 to 21 of age. In Experiment 1, one day old male broiler chicks (n=210) were assigned to one of 7 treatments, with 3 replicates of 10 birds each. Animals in treatment 1 (T1) were fed a basal diet formulated to be deficient in nonphytate P (0.14%). Birds in T2 and T3 received the basal diet supplemented with 0.05% or 0.10% of P from monodicalcium phosphate (MCP), respectively. Phosphorus from DDGS was added to diets in T4 (0.05% from DDGS A), T5 (0.1% from DDGS A), T6 (0.05% from DDGS B) and T7 (0.1% from DDGS B). Percent of inclusion of DDGS was dictated by total P content as determined by chemical analyses. Growth performance and P intake were assessed in all birds. Phosphorus bioavailability was determined using the slope ratio assay, with tibia ash as the response variable. For Experiment 2, one-day-old male broiler chicks (n=200), were assigned to 5 treatments with 4 replicates of 10 birds each. A sorghum-soya control diet was given to animals in T1. Treatments 2 and 3 included this same diet supplemented with either 5% or 10% of DDGS A. Birds in T4 and 5 received the control diet with either- 5% or 10% of DDGS B. Amino acid digestibility was measured from ileal contents in 7 euthanized birds from each group at day 21. Apparent metabolizable energy was determined in oven dried feces from all animals during the last 3 days of the experiment.  Weight gain and feed consumption increased (P <0.001) with larger inclusion of dietary P in birds from experiment 1. Relative P bioavailability for DDGS A and B was 72% and 86% respectively, from a P total content of 0.85% and 0.94%.,. Growth performance was similar for all treatment groups in experiment 2 (P >0.05). The average apparent ileal amino acid digestibility coefficient for DDGS A 76.5% and B was 76.4%. No differences were found for essential AA coefficients between the two DDGS (P >0.05). The AMEn values on a dry matter basis were 2828 and 2854 kcal/kg for DDGS A and B, respectively.

The objective of this study was to determine the energy values, standardized ileal digestibility coefficients and digestible amino acid contents of parboiled brown rice bran (PBRB), protein sorghum meal (PSM) and bread waste meal (BWM) in broiler diets. In the first trial, 144 broiler chicks at 14 days of age were evaluated in a completely randomized design involving three feedstuffs + a control diet, with six replicates and six birds per experimental unit. The total excreta collection method was adopted to determine the energy values of the feedstuffs. In the second trial, 144 broilers at 24 days of age were used in a completely randomized design involving three feedstuffs + a protein-free diet, with six replicates and six birds per experimental unit. Ileal digesta was harvested to determine the standardized ileal digestibility coefficients and digestible amino acid contents of the feedstuffs. The nitrogen-corrected apparent metabolizable energy (AMEn) values of PBRB, PSM and BWM were 2638, 2799 and 3399 kcal.kg-1, respectively. The metabolizability coefficients of AMEn (CAMEn) of PBRB, PSM and BWM were 54.13, 57.35 and 86.66%, respectively. Bread waste meal had the highest CAMEn (p < 0.05) and standardized ileal digestibility of amino acids (p < 0.01), followed by PBRB and PSM. The main limiting digestible amino acids in PBRB, PSM and BWM were found at the following respective levels: methionine - 0.19, 0.33 and 0.24%; lysine - 0.40, 0.46 and 0.40%; threonine - 0.25, 0.50 and 0.45%; and valine - 0.44, 0.73 and 0.48%.

Abstract The aims of this experiment were to determine the energy value of raw grains [corn (CO), red sorghum (RS), white sorghum (WS)], in comparison to the energy values of the same grains post-extrusion. Cecectomized roosters were precision-fed up to 30g of either raw or extruded grains, then placed into individual cages with a collection tray underneath to catch excreta. After 48h, the excreta was collected and analyzed for N, gross energy, amino acids and dry matter. TMEn was highest (P &lt; 0.05) for extruded WS (3.99 kcal/g) and lowest for raw WS (3.79 kcal/g), whereas extruded CO (3.89 kcal/g), and extruded RS (3.89 kcal/g) did not differ from raw RS (3.83 kcal/g) and raw CO (3.82 kcal/g). This indicates that there was greater utilization of the extruded grains compared to the raw, especially for WS. Amino acids were measured in the grains and the excreta to determine the digestibility. In addition to the rooster assay, a chick growth assay was conducted using Ross 308 male broiler chicks. The study lasted 14d, with average initial chick BW being 149.1g ± 0.048. The experimental diets consisted of inclusion of raw and extruded grains, respectively, added at direct substitution of corn. The results of the chick trial appear to be controversial to the rooster assay. The extruded CO and extruded WS diets were similar (P &gt; 0.05) in weight gain compared to raw CO (660.84g, 665.70g, and 690.13g, respectively). Extruded WS had the greatest (P &lt; 0.05) feed intake (973.3g), with raw RS having the lowest (847.44g). Raw CO had the greatest (P &lt; 0.05) G:F, with extruded WS being lowest (P &lt; 0.05); 754.63g and 683.75g, respectively. In conclusion, the chick growth assay showed superior weight gain in the extruded CO and WS diets, however, the extruded diets were least successful in G:F compared to the raw.

Abstract An experiment was conducted to investigate the effect of rice bran (RB) and Ronozyme® WX on apparent and true ileal amino acid (AA) digestibility coefficients in broiler chicks using a regression approach. Two hundred and forty 21-day-old Abor Acre plus chicks were randomly allotted to six diets with varying levels of RB (100, 200 and 300 g/kg) without (0g/kg) or with Ronozyme® WX (25g/kg) supplementation in a 2x3 factorial arrangement using a randomized complete block design. Each treatment had 5 replicates with 8 birds each. The birds were fed for 5 days (d 22–26). On d 26, digesta was sampled from distal ileum. Data were analyzed using general linear model at α0.05. Lysine had the highest concentration among the essential amino acids (AAs) while the lowest concentration was observed for threonine. Rice bran at 10% for the essential amino acids with enzyme was significantly higher but compared with concentrations of RB at 10% and 20% without enzyme. There were no significant differences among the true ileal amino acid digestibility coefficients except lysine (10% RB) without enzyme (0.91) which was significantly higher than 20% RB with enzyme (0.84) but similar to other treatments. Rice bran with enzyme had a significant (P &lt; 0.05) interactive effect on the apparent ileal digestibility coefficients of arginine, histidine, isoleucine methionine and phenylalanine. When RB was supplemented with enzyme, a significant (P &lt; 0.05) interactive effect on true ileal digestibility coefficients of arginine and methionine was observed. Rice bran-enzyme interaction had no significant effect on the non-essential AAs. The slopes of the regression lines ranged from 0.77 (arginine) to 0.98 (phenylalanine). In conclusion, enzyme supplementation did not significantly influence the digestibility coefficients of AA in rice bran. However, the inclusion of 10% and 20% RB supplemented with Ronozyme® can help to improve the methionine content in rice bran.

Sorghum grain (SG) contained more crude protein (103.5 g/kg) and ash (17.0 g/kg) but less crude fiber (17.7 g/kg) and total lipid (22.6 g/kg) than corn. The SG contained 0.37% ± 0.02 tannin, had a higher apparent metabolizable energy value than corn or wheat and contained all of the amino acids considered essential for chickens at levels in general between those of corn and wheat. Two experiments were carried out to ascertain the nutritive value of SG as a partial replacement for corn and wheat in practical poultry diets using 320 male and 320 female Cobb chicks in each. Starter (finisher) diets fed from 0–21 days (22–42 days) contained the following levels of SG: 15 (19); 30 (39); 45 (58)%. The diets were isoenergic and isonitrogenous. The inclusion of up to 45% SG in the starter diet and up to 58% in the finisher diet had no significant effect on mortality, live body weight, feed conversion or percentage of grade A carcasses.
