This study aimed to evaluate açaí meal in diets for commercial laying hens on apparent nutrient digestibility and apparent metabolizable energy. A total of 72 Hissex White laying hens (52-wks-old) were distributed in a completely randomized design, where treatments consisted of a control diet and an experimental diet (25% açaí meal) with six replicates of six birds each. Data collected were subjected to polynomial regression at 5%. Differences (p < 0.05) were detected in digestibility of all evaluated nutrients. Hens fed diets with 25% açaí meal presented worse (p < 0.05) metabolization and use of energy content. It can be concluded that hens fed diets containing açaí meal presented better use of crude protein, non-fiber carbohydrates and mineral matter. However, there was worse use of dry matter, fiber carbohydrates and ether extract. This result directly affected the energy metabolism of the birds. The inclusion of açaí meal reduced the energy use.

An experiment was conducted to determine the effect of feeding concentrate diets containing varying levels of groundnut haulms on dry matter intake, nutrient digestibility and nutrient balance in Friesian x Bunaji bulls. The feed consisted of four concentrate mixed diets formulated to contain on average 14.45- 14.65% crude protein. Groundnut haulms (GH) in the concentrate diets were on nitrogen basis at 0, 25, 50 and 75% levels with control diet having 0% inclusion of GH. Sixteen bulls aged 12-18months were divided into four each and were randomly allotted to the four treatment diets in a completely randomized design for metabolic trial. During trial, the bulls were housed in metabolic crates and fed Gamba hay adlib and the basal or particular test concentrate mixture at 40% of estimated DM intake. Chemical composition and energy contents of the diets were determined. Dry matter intake (D M ) and organic matter intake (OMI) were also determined. The CP value averaged 14.45±0.44 - 14.65±1.22% for the four experimental diets. The metabolizable energy content expressed in Kcal/kg of diets decreased with increase in GH level from 0-75% (3166-1752 kcal/kg). There was no significant (P>0.05) difference on voluntary DMI and OMI. The digestibility coefficients of DM, OM, CP, CF, EE, NDF, ADF, hemicellulose and ash were significantly (P<0.05) higher at 75% level of groundnut haulms. CF and ADF digestibility were significantly influenced (P<0.05) when groundnut haulms level reached 25%. Conversely, the digestibility of NFE did not differ (P>0.05) across treatments. Nitrogen balance were similar (P>0.05) among animals fed concentrate mixtures. Nitrogen balance expressed in percent was slightly higher at 75% level of groundnut haulms. It is concluded that inclusion of GH in concentrate diets of crossed bulls up to 75% can improve nutrient digestibility and the percent Nitrogen balance.

The objective of this study was to evaluate the effects of acid silage meal made of pirarucu waste in diets for commercial laying hens on apparent digestibility and energy metabolism. Seventy-two Hisex White hens with 71 weeks of age were assigned to a completely randomized with two treatments (control diet and diet with 3% pirarucu waste acid silage) with six replicates of six birds each. The ensiled biomass was light brown in color, showing acidified aroma; creamy consistency; 4.38±0.11 pH; 84.16% dry matter; 40.06% crude protein; 26.82% ether extract; 9.31% mineral matter, 65.16 g kg-1 calcium and 22.90 g kg-1 phosphorus. Differences (p > 0.05) were detected in digestibility of crude protein, non-fiber carbohydrates (soluble carbohydrates), etherextract, mineral matter, metabolizable energy and metabolizable energy coefficient. Our results indicate that the acid silage mealmade of pirarucu waste can be included up to 3% in diets for laying hens, showing satisfactory nutrient digestibility and potential to be used as an energy source.

The experiments were conducted to evaluate the effects of whole wheat on the production performance, egg quality, and nutrient digestibility when supplemented primarily at the expense of corn in ground corn-soybean meal control diets. The experiments utilized Lohmann Brown Classic laying hens from 45 to 53 wk of age. The results were shown that feeding 5, 10, 15, 20, or25% whole wheat in diet had no effect on the production performance and egg quality, whereas 15, 20, and 25% whole wheat in diet decreased the yolk color (based on the Roche color fan score) when compared with layers fed the control diet.Whole wheat level in diet had no effect on dry matter,organic matter digestibility, and apparent metabolizable energy when compared with laying hens fed the control diet. Therefore, whole wheat can be used at levels of up to 25% in laying hen diets without negatively affecting the production performance, but levels over 15% whole wheat decreased the yolk color.

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.

Two experiments were conducted to evaluate diet digestibility, performance, digestive parameters, and blood parameters when an enzyme complex (EC) was used in barley- and rye-based diets with different energy levels. In the digestibility assay (exp. I), 108 seventeen-day-old Cobb male broilers were distributed in a completely randomized design in 2 × 2 × 2 + 1 factorial arrangement with two feeds (barley or rye), two EC levels (0% and 0.02%), and two energy levels [3025 and 3125 kcal apparent metabolizable energy (AME)·kg−1], plus a control treatment. In exp. II, 1080 one-day-old Cobb male broilers were distributed in a completely randomized design in 2 × 2 × 2 + 1 factorial arrangement with two feeds (barley or rye), two EC levels (0% and 0.02%), and two energy levels (2875 and 2975 kcal AME·kg−1). No interactions were observed for any variables (exp. I and II). Enzyme complex improved the apparent metabolizable coefficient of gross energy (P = 0.0432) of diets. The EC provided greater weight gain (P = 0.0003) and better feed conversion (P = 0.0025). Intestinal viscosity at 21 d was reduced (P < 0.0001) with the addition of the EC. The EC improved nutrient digestibility and performance, but the effects of energy reduction on performance could not be overcome.

This study evaluated the effects of feeding whole rice bran (WRB) stored for different times and treated with a mixture of organic acids on the growth performance, nutrient digestibility, duodenal morphometry, and bone characteristics of broiler chickens. Three hundred and twenty 1-d-old Cobb broilers were used in a 21 d experiment with a completely randomized design. Whole rice bran with five storage times (0, 30, 60, 90, and 120 d) was included at a 12% level in the diets, with eight replicates of eight birds each. A polynomial regression with a significance level of 5% was used. A reduction in daily weight gain was observed in birds fed WRB stored up to 90 d. A quadratic response was observed in the daily feed intake and average body weight of birds fed diets containing WRB treated with a mixture of organic acids and stored up to 90 d. There was a linear increase in the digestibility of crude protein with increased WRB storage time. Apparent metabolizable energy and apparent metabolizable energy corrected for nitrogen showed an increasing quadratic response for up to 60 d of WRB storage and treated with a mixture of organic acids. A quadratic response for the morphometry of intestinal crypts was found. The crypt depth increased as the birds were fed a diet containing WRB treated with a mixture of organic acids, stored up to 30 d and decreased with storage times. In conclusion, WRB treated with a mixture of acetic and propionic acids and stored up to 60 d may be safely added to broiler chicken diets.

A total of twenty-five crossbred rabbit bucks with a mean weight of 628.73g were utilized to investigate their nutrient digestibility, visceral organ changes, and carcass yield when fed with diets containing graded levels of rumen filtrate-fermented rice offal (FRO) for 10 weeks. Five rabbits were grouped into five treatments with each rabbit serving as a replicate in a completely randomized design experiment. The control group was fed with a diet containing no rumen filtrate fermented-rice offal meal while the other four groups were fed with diets in which the FRO replaced the maize at 5%, 10%, 15%, and 20%, respectively. The results of the analyzed nutrient composition and energy content of the experimental diets showed no trend across the treatments except for crude protein and metabolizable energy whose values appeared to increase across treatments as the levels of FRO increased from 0% to 20%. Dry Matter (DM), Crude Fiber (CF), Ether Extract (EE) and Nitrogen Free Extract (NFE) digestibility values were affected by the inclusion level of the fermented rice offal in the diets of the rabbits, except Crude Protein (CP). Crude fiber values appeared to increase across the treatments as the levels of FRO increased from 0% to 20%. Dressed weight showed significantly (p<0.05) higher values for rabbits fed with diets containing 20% FRO and prime cuts were significantly (p<0.05) influenced by treatments. The result of visceral organ and GIT weights showed treatment effect (p<0.05), except fasted live weights, spleen, and visceral fats. Of the visceral organ lengths, only the esophagus and stomach were similar (p>0.05) across treatment groups. It was therefore concluded that the digestibility of nutrients was not adversely affected; such that 20% inclusion of rumen filtrate-fermented rice offal showed no modification on visceral organ changes and a better carcass yield observed in rabbits on the diets. It was suggested that up to 20% rumen filtrate-fermented rice offal meal can be integrated into rabbit diets without impairing their digestibility, visceral organ characteristics, and carcass yield.

The objective of this study was to determine the chemical and energy composition of spirulina (Spirulina platensis), the nutrient metabolizability coefficients, and the values of apparent metabolizable energy (AME) and the apparent metabolizable energy corrected for nitrogen balance (AMEn) in broilers. A digestibility trial was carried out by using total excreta collection method, with 90 Cobb 500 lineage chicks, with initial weight of 256 ± 5 g at 11 days of age. Birds were allotted in metabolic cages for 10 days, distributed in a completely randomized design, with three treatments and six repetitions with five birds each. Diets consisted on a reference-ration based on corn and soybean meal and two test diets, one containing spirulina (30%) and the other one with soybean meal (30%). Spiruline was superior to soybean meal for contents of dry matter (DM), gross energy (9.60%), crude protein (26.56%), ether extract (54.45%), mineral matter (42.77%), calcium (100%) and total phosphorus (130.77%) and also for most amino acids, except lysine, glutamate, histidine and proline. Nevertheless, spiruline presented lower values of gross fiber (83.95%), acid detergent fiber (85.12%) and neutral detergent fiber (6.15). The AME and AMEn values (kcal/kg of DM) were, respectively, 2,906 and 2,502 for the spirulina and 2,646 and 2,340 for the soybean meal and AMEn of spirulina was 6.92% higher than soybean meal.

<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>
