This study examined the effect of exogenous mixed-enzyme supplementation (xylanase, β-glucanase, and pectinase) to a corn-SBM (CS) and a wheat-CS-based (WCS) diet in birds challenged with coccidia vaccine (Coccivac B-52™). The WCS-based diet was produced by replacing 30% of the energy-yielding portions of the CS-based diet with wheat. On day 14, 448 (n = 7) Cobb by-product breeder male broilers were assigned to a 2 (diet types) × 2 (with or without enzyme supplementation) × 2 (0 or 20 × coccidia vaccine challenge; CVC) factorial arrangement of treatments in a completely randomized design for the determination of the apparent metabolizable energy (AME) value of wheat. Treatment effects on jejunum digesta viscosity and AME corrected for nitrogen (AMEn) of the diets were evaluated within each diet type as a 2 × 2 factorial arrangement of treatments, 7- and 14-day post-challenge. Seven-day post-challenge (day 21), dry matter (DM) and energy utilization, AME, and AMEn of the CS- and WCS-based diets decreased (p < 0.05) with CVC. Both AME and AMEn of wheat decreased (p < 0.05) by about a 20% in CVC-birds 7-day post-challenge. Enzyme and CVC resulted in a decrease (p < 0.05) in jejunal digesta viscosity in birds fed the CS-based diets, while there was an interaction (p < 0.05) between CVC and enzyme, with enzyme lowering (p < 0.05) the viscosity of digesta 7-day post-challenge. Results from this study showed that CVC resulted in a 20% decrease in AMEn 7-day post-challenge, while the interaction between exogenous enzyme supplementation and CVC resulted in an improvement in nitrogen utilization (~6%) in CVC birds fed the corn-SBM-based diet 7-days post challenge.

An experiment was conducted to evaluate the energy and protein of Brewers' Dried Grains (BDG) produced from different proportions of harley, maize and sorghum on the performance of rabbits. Sixteen (16) rabbits made up of New Zealand and Chinchilla, eight (8) weeks old averaging 1.20kg were used in the trial in a completely randomized design. The four (4) diets were BDG (maize: barley: sorghum) (BDG MBS); BDG (maize: harley) (BDGMB); BDG (maize: sorghum) (BDG MS) and BDG (sorghum) (BDG S). The diets were the only source of protein and energy. The treatment effect was significant (p < 0.05) with the highest crude protein digestibility and nitrogen retention values recorded for BDG MBS. The digestible and metabolizable energy values were not significantly different (p > 0.05) for the BDG investigated. The digestible energy values determined for BDG MS, BDGS, BDG MBS and BDG MB in W/kg of dry matter were 16.97, 15.57, 14.84 and 13.35 respectively while the values for ME in MJ/kg of dry matter were 16.32, 14.91, 14.31 and 12.34 respectively. BDG from local sources have potential to make complete feed for rabbits judging from their impressive energy and protein values.

<p>The objective of this study was to determine the chemical composition, apparent metabolizable energy (AME), AME corrected by nitrogen retention (AMEn) and metabolization coefficients (MC and MCn) of different feeds for broilers from the western region of Paraná State. The experiment was conducted at the Physiology of Birds Laboratory at UNIOESTE. Two hundred and sixty male chicks of the Cobb 500 strain, at 21 days old, were distributed in a randomized design with 12 treatments and four replicates of five birds per experimental unit. The feed ingredients studied were ten different wheat middlings, one triticale, one wheat grain and a reference diet. Values for dry matter, nitrogen, gross energy, neutral detergent fiber, acid detergent fiber, mineral matter, calcium, phosphorus, sodium, potassium and magnesium composition were determined as well as the geometric mean diameter of the feed particles. To determine the apparent metabolizable energy (AME) and AME corrected for nitrogen balance (AMEn) the total excreta collection method was used with growing birds. The chemical composition of the feeds was variable. The values for AME and AMEn ranged from 1. 819-2. 958 and 1. 734-2. 882 kcal. kg-1, respectively. Based on these energetic values and the values for gross energy, the coefficients of metabolizability were calculated. The values ranged from 43. 26-75. 24% for MC and from 42. 28- 73. 31% for MCn.</p>

Collection Methods

The objective was to evaluate three sources of acid insoluble ash (AIA) (celite, kaolin, and sand), as indicators, to determine the apparent metabolizable energy of corn on a natural matter (AME) basis, dry matter digestibility coefficient (DMDC), and crude protein digestibility coefficient (CPDC) using total and partial excreta collection methods. Two hundred and ten Ross broiler chicks of 18 to 27 days of age were used. Broilers were adapted to experimental the diet for four days, and excreta were collected for 5 days. A reference diet (RD) based on corn and soybean meal was prepared to meet the nutritional requirements of the birds. A test diet was prepared with 40% replacement of RD with corn. The formulated diets were: D1, 99% Reference diet + 1% celite; D2, 59.4% RD + 39.6 % corn + 1% celite; D3, 99% Reference diet + 1% kaolin; D4, 59.4% RD + 39.6 % corn + 1% kaolin; D5, 99% Reference diet + 1% sand; D6, 59.4% RD + 39.6 % corn + 1% sand. The treatments were distributed in a completely randomized design, with six diets and five replicates of seven birds each in a 2x3 factorial arrangement. There were significant interactions for all variables investigated. It was observed that the AME and DMDC values of corn were similar in the two methods of collection, and PDC values using kaolin and celite makers were similar. However, the AME and CPDC of corn using sand with partial collection method were underestimated by 17.70 and 15.53%, respectively compared to those with the total collection method. The AME values of corn with the collection methods using celite and, the DMDC using celite and sand were significantly different. It was observed that the DMDC using celite and sand provided significantly lower values (4.67 and 5.15%), respectively, and the AME using celite was 2.86% lower than that obtained by total collection. To determine the EMA, DMDC, and CPDC in broilers, it is more efficient to use celiteTM and kaolin as markers with partial collection of excreta. Sand should not be used with partial excreta collection method, because it provides lower values of AME and CPDC compared to with total excreta collection method.

AbstractThe nutritional value of different categories of peas was measured in mash or pelleted diets using adult cockerels. Twenty-five round and white-flowered peas (feed peas), 12 round and coloured-flowered peas and five wrinkled and white-flowered peas were used in mash diets. From the same batches, 11 feed peas, five coloured peas and four wrinkled peas were tested in pelleted diets.Mean apparent metabolizable energy (AME) values were 12·02, 11·35 and 10·50 MJ/kg dry matter (DM) for feed peas, coloured peas and wrinkled peas respectively in mash diets and 13·18, 12·72 and 11·63 MJ/kg DM for the same categories in pelleted diets.Mean starch digestibility was 0·905, 0·887 and 0·802 for feed peas, coloured peas and wrinkled peas respectively in mash diets and 0·985, 0·984 and 0·840 for these categories in pelleted diets.Mean protein digestibility was 0·788, 0·643 and 0·798 for feed peas, coloured peas and wrinkled peas respectively in mash diets and corresponding values for peas in pelleted diets were 0·855, 0·743 and 0·853.Pelleting thus had a positive effect on the nutritional value of peas and this improvement was all the more important because the AME and protein digestibility of the pea in mash diets was low.The nutritional value of feed peas for cockerels was not strongly correlated with chemical composition or to digestibility data obtained in the pig.

The effects of added crude enzyme preparations, autoclaving and dehulling on the nutritional value of diets containing a low-tannin (Trapper) and high-tannin (Maple) cultivar of peas (Pisum sativum L.) for chicks were determined in four experiments. The addition of crude enzymes from different sources and at different concentrations to a diet containing 75% of the low-tannin peas did not improve chick performance (exp. 1). Similarly, no improvement in performance was observed when a combination of crude enzymes was added to the diet containing whole or dehulled low-tannin peas, (exp. 2). Autoclaved treatment and enzyme addition to the diet containing the high-tannin Maple peas improved (P < 0.05) the feed-to-gain ratio but not the weight gain (exp. 3). Autoclaving or dehulling improved the apparent metabolizable energy (21 vs. 30%) and apparent protein digestibility (11 vs. 15%) of the high-tannin peas, respectively, in contrast to the low-tannin peas (experiment 4). Dehulling improved the feed-to-gain ratio of chickens fed both cultivars of peas. In conclusion, the results indicate that addition of crude enzymes to diets containing raw or dehulled low-tannin peas do not improve the chick performance but improve the feed efficiency of chicks when fed with the high-tannin peas. Autoclaving and dehulling improved the apparent metabolizable energy and protein digestibility values of high-tannin Maple peas while dehulling improved the feed-to-gain ratio of both cultivars.

Water Extractable

Two pentosan-rich fractions (water-extractable, WEP, and alkali-extractable, AEP) were isolated from a wheat milling by-product. When both WEP and AEP were added to a commercial-type broiler diet the apparent metabolizable energy (AME), nitrogen retention, feed utilization and growth of broilers were significantly (P < 0.001) depressed. These depressions were closely correlated (P < 0.001) to the level of pentosans in the diets. At the highest level of inclusion of pentosans (equivalent to 40 g arabinoxylans as AEP/kg) the ileal digestibilities of starch, protein and lipid were decreased by 14.6, 18.7 and 25.8% respectively.Anti-nutritive effects: Non-starch polysaccharides: Broiler diets

The Experiment was conducted to study effects of binder mineral addition to the hatchery waste based pelletprocessingon its proximate component and energy value. The study may be beneficial to emerge a new feed resource for local farm businesses. The hatchery wastes those comprised of 30% of egg shells, 60% of un-hatched eggs, and 10% of culled DOC were blended, and mixed with 10% of cassava cake meal(W/W), then mixed well with mineral adsorbent (bentonites or zeolites) at 0, 1, 2, 3, 4 and 5% (W/W). The mixture was conditioned at 80 ºC for 15 min, and extruded to make a pellet with 6 mm of diameter and 30 mm in length, and dried into warm air flow dryer. The moisture, crude protein (CP), ash, ether extract (EE), crude fiber (CF), apparent metabolizable energy (AME), true metabolizable energy (TME), metabolizability(MET) and nitrogen retention (NR) were observed in each pellet. Result of the experiment showed that moisture of pellet was decreased (P<0.05) by zeolites or bentonites addition. Even though the effect ofbinder mineral addition gave different patterns, concentrations of ash, crude protein, ether extract and crude fiber of pellet product were increased by increasing level of mineral adsorbent (P<0.05). Nutrient availability as was represented by AME, TME, MET, and NR were increased by zeolites and bentonites additions (P<0.05). In conclusion, supplementations of bentonites and zeolites in the hatchery waste based pelletcould improve its proximate component concentration and nutrient availability.

Energy Coefficient

The efficiency with which the gross energy content of herring (Clupea harengus), mackerel (Scomber scombrus), and trout (Oncorhynchus mykiss) is metabolized was determined for 11 captive Great Blue Herons (Ardea herodias). There was a linear relationship between apparent metabolized energy and gross energy intake for the mackerel and trout. This relationship was lower and more variable for herring. Estimates of the apparent metabolizable energy coefficient for mackerel and trout were affected by the level of energy intake. Correcting for endogenous energy losses in the excreta yielded estimates of true metabolizable energy coefficients that were independent of gross energy intake. The true metabolizable energy coefficient of mackerel and trout did not differ and averaged 0.866 (SD = 0.014, n = 3 diets). Correcting for nitrogen retention did not improve the estimate of the metabolizable energy coefficient. The metabolizable energy coefficient of herring was highly variable and showed no consistent pattern in relation to energy intake.

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.
