Abstract:
Feed accounts for the highest cost associated in poultry production, with energy-containing feedstuffs being the most expensive portion of the cost of feeding. The increasing demand for poultry meat gives reason to determine accurate apparent metabolizable energy (AME) values for various feedstuff through measuring energy utilization in the birds. The adaptation length of birds fed an experimental diet may affect the determined AME value due to the diet matrix and physiochemical properties of the feedstuff. Therefore, the objective of this thesis was to evaluate a select group of energy-containing feedstuff with different diets and with factors such as coccidia challenge and exogenous enzyme supplementation that may influence the determined AME values in broiler chickens.

Abstract:
Determining the energy values of feed ingredients for poultry is of great concern, especially since production efficiency is associated with profit margins. Therefore, accurate, precise, and reproducible energy values for feed ingredients are of the utmost importance in formulating an economical diet. An important aspect in determining the apparent metabolizable energy (AME) of a feed ingredient is the procedure employed in the drying of excreta samples. During sample preparation, substantial grinding losses were incurred amounting to 3.5 to 5.2% of the dried sample weight. Also moisture uptake during sample grinding accounted for a 1.9 to 3.9% increase in sample weight. To properly account for such losses, freshly collected excreta samples should be weighed, oven-dried at 40 C, reweighed, allowed to equilibrate with atmospheric moisture, weighed, ground, reweighed, and stored in air-tight containers for subsequent analyses. From the oven-drying of feed and excreta samples at various temperatures, a linear decrease in sample weight occurred with increasing drying temperatures. When dried at 100 C or less, the energy content of feed and excreta samples remained unchanged, but increased significantly at higher temperatures. The nitrogen composition of feed and excreta samples exhibited a similar trend, but a significant loss of excreta nitrogen (2%) occurred at 100 C. The loss of excreta nitrogen at a temperature of 100 C is of relatively minor consequence in the determination of metabolizable dry matter, but is of major concern in nitrogen balance studies. Extraction of feed and excreta samples with N,N-dimethylformamide and titration with Karl Fischer reagent indicated that significant amounts of water were retained by samples dried at 40, 60, and 80 C. However, at temperatures of 100 C or greater, little water was retained but sample decomposition occurred. A drying temperature of 90 C or the Karl Fischer method may yield a more accurate value for the dry matter of feed or excreta. When seven roosters were subjected to a total collection method for five consecutive days, individual birds were better metabolizers of dry matter and energy than others. By either a voluntary intake method or by a total collection method, values for the nitrogen-corrected metabolizable energy of corn were similar. The total collection method proved to be more reliable since it provided the least amount of variation when ad libitum feed intake and total excreta output were measured over a period of several days. In past experiments, adding fats to a test diet at the expense of cerelose in amounts no greater than 20% of the diet to determine the metabolizable energy of the fat has been associated with a high degree of variability. From the force-feeding of fats at levels to 100%, the variation associated with the metabolizable energy value of a fat was greatly reduced. The methodology presented here provided reliable estimates and detected differences between the metabolizable energy of two feed-grade fats in comparison to previous methods.

Abstract:

Determination of metabolizable energy (ME) and amino acid (AA) digestibility values of single feed indigents continues to be two of the most important aspects for successful least-cost poultry feed formulation. It would be advantageous if a common diet type could be utilized to determine both ME and AA digestibility values of feed ingredients within a single assay. Two experiments were conducted to evaluate the effect of basal diet type and excreta collection method on the ME value of single feed ingredients determined in broiler chicks using the regression method. In experiment 1, the objective was to investigate the influence of semi-purified (SP) and corn-soybean meal (CSBM) based diet types on the nitrogen-corrected ME (MEn) of dextrose when determined by regression and to compare MEn values using the index and total excreta collection (TC) methods. The dextrose-associated caloric intake was regressed against the amount of dextrose intake to generate linear regression equations with slopes corresponding to the MEn value of dextrose within each basal type. The resulting dextrose ME n values determined using SP basal diets (3,502 and 3,553 kcal/kg) were similar (P > 0.05) to those determined using CSBM basal diets (3,839 and 3,588 kcal/kg) for index and TC procedures. In experiment 2, the influence of basal diet type on the ME and MEn values of an expeller-extruded soybean meal (EE-SBM) generated in broiler chicks using the regression method were evaluated. Linear regressions of EE-SBM associated MEn intake in kcal against EE-SBM intake in kg resulted in similar (P > 0.05) MEn values for SP (2,542 kcal/kg) and for CSBM (2,575 kcal/kg) diets. These results indicate that both total collection and index procedures may be reliably used to characterize the MEn content of feed ingredients, and that similar estimates of ingredient MEn can be determined in SP and CSBM diets, potentially allowing for simultaneous determination of ME and AA digestibility in a single study.

Com esse estudo objetivou-se determinar e validar equaÃÃes de prediÃÃo para energia digestÃvel (ED) e metabolizÃvel (EM) do milho e do farelo de soja com suÃnos em crescimento. Para obtenÃÃo das equaÃÃes de prediÃÃo foram utilizados dados de composiÃÃo quÃmica, digestibilidade e metabolizabilidade de 30 amostras de grÃos de milho e 25 amostras de farelo de soja avaliadas em experimentos na Embrapa SuÃnos e Aves, sendo as equaÃÃes estimadas por meio da anÃlise de regressÃo, utilizando-se o procedimento REG do pacote estatÃstico SAS e o RÂ ajustado como critÃrio de escolha para selecionar os melhores modelos. Foram estimadas duas equaÃÃo para ED e duas para EM, do milho e do farelo de soja. Para a validaÃÃo das equaÃÃes foram realizados dois experimentos para a determinaÃÃo dos valores de ED e EM de cinco amostras de milho (Experimento I) e cinco amostras de farelo de soja (Experimento II). Em cada experimento, 48 leitÃes machos castrados, com peso inicial de 54,21Â1,68 kg (Experimento I) e 54,40Â1,76 kg (Experimento II), foram distribuÃdos em um delineamento em blocos ao acaso, com 6 tratamentos (Experimento I: 1 raÃÃo referÃncia e 5 raÃÃes testes, compostas por 60% da dieta referÃncia e 40% de diferentes milhos e para o Experimento II: 1 raÃÃo referÃncia e 5 raÃÃes testes, compostas por 70% da dieta referÃncia e 30% de diferentes farelos de soja) e 8 repetiÃÃes, sendo a unidade experimental constituÃda por um animal. Com base nos resultados de ED e EM obtidos nos experimentos e os valores preditos nas equaÃÃes, procedeu-se a validaÃÃo das equaÃÃes, utilizando-se o procedimento REG do programa SAS, sendo o critÃrio de seleÃÃo o menor erro de prediÃÃo (ep). ApÃs a validaÃÃo, as equaÃÃes que melhor se ajustaram para prediÃÃo dos valores de energia digestÃvel e metabolizÃvel do milho para suÃnos em crescimento foram as seguintes: ED = 11812 â 1015,9(PB) â 837,9(EE) â 1641(FDA) + 2616,3(MM) + 47,5(PB2) + 114,7(FB2) + 46(FDA2) â 1,6(FDN2) â 997,1(MM2) + 151,9(EEFB) + 23,2(EEFDN) â 126,4(PBFB) + 136,4(PBFDA) â 4,0(PBFDN), com R2 de 0,81 e ep = 2,33 e EM = 12574 â 1254,9(PB) â 1140,5(EE) â 1359,9(FDA) + 2816,3(MM) + 77,6(PB2) + 92,3(FB2) + 54,1(FDA2) â 1,8(FDN2) â 1097,2(MM2) + 240,6(EEFB) + 26,3(EEFDN) â 157,4(PBFB) + 96,5(PBFDA) â 4,4(PBFDN), com R2 de 0,89 e ep = 2,24. Para o farelo de soja as equaÃÃes que melhor se ajustaram foram: ED = 48153 â 1586,1(PB) + 744,5(EE) + 363,6(FB) â 1398,3(MM) + 15,5(PB2) â 170,8(EE2) â 29,3(FB2) + 5,4(FDA2) â 2,5(FDN2) + 90,6(MM2) â 48,2(EEFDA) + 33(EEFDN), com RÂ de 0,88 e o ep = 2,32, EM=12692 â 2397,7(MM) â 56,8(EE2) + 164,9(MM2) â 102,2(EEFB) â 12,25(EEFDA) + 67,6(EEFDN) + 5,5(PBFB) â 2,9(PBFDN) com R2 de 0,65 e o ep = 1,69
The aim of this study was to determine and validate prediction equations for digestible (DE) and metabolizable energy (ME) of corn and soybean meal for growing pigs. The prediction equations were developed using data from chemical composition and digestibility and metabolizability of 30 and 25 samples of corn grain and soybean meal, respectively, evaluated in experiments at the Embrapa SuÃnos e Aves. The equations were estimated through regression analysis, using the REG procedure of SAS and adjusted RÂ was the criterion of choice to select the best models. Two equations were estimated for DE and two for ME, of corn and soybean meal. To validate the equations, two experiments were performed to determine the values of DE and ME with five samples of corn grain (Experiment I) and five samples of soybean meal (Experiment II). In each experiment, 48 growing pigs with an initial weight of 54,21Â1,68 kg (Experiment I) and 54.40 Â 1.76 kg (Experiment II), were sorted in a complete randomized block design with 6 treatments (Experiment I: 1 reference diet and 5 test diets composed of 60% of the reference diet and 40% corn, and Experiment II: 1 reference diet and 5 test diets composed of 70% of the reference diet and 30% soybean meal) and 8 replicates. The experimental unit was the animal. Based on the DE and ME values obtained in the experiments, and in the predicted values obtained with the equations, we proceeded to validate the equations, using the REG procedure of SAS. The criterion for selection of the best model was the lowest prediction error (pe). After validation, the equations that best fit to estimate the digestible and metabolizable energy of corn for growing pigs were: DE = 11812 â (1015.9CP) â (837.9EE) â (1641ADF) + (2616.3Ash) + (47.5CP2) + (114.7CF2) + (46ADF2) â (1.6NDF2) â (997.1Ash2) + (151.9EECF) + (23.2EENDF) â (126.4CPCF) + (136.4CPADF) â (4.0CPNDF), with R2 = 0.81; pe = 2.33 and ME = 12574 â (1254.9CP) â (1140.5EE) â (1359.9ADF) + (2816.3Ash) + (77.6CP2) + (92.3CF2) + (54.1ADF2) â (1.8NDF2) â (1097.2Ash2) + (240.6EECF) + (26.3EENDF) â (157.4CPCF) + (96.5CPADF) â (4.4CPNDF), with R2 = 0.89 e pe = 2.24. For soybean meal the equations that best fit were: DE = 48153 â (1586,1CP) + (744,5EE) + (363,6CF) â (1398,3Ash) + (15,5CP2) â (170,8EE2) â (29,3CF2) + (5,4ADF2) â (2,5NDF2) + (90,6Ash2) â (48,2EEADF) + (33EENDF), with RÂ = 0.88 and pe = 2.32 e ME = 12692 â (2397,7Ash) â (56,8EE2) + (164,9Ash2) â (102,2EECF) â (12,2EEADF) + (67,6EENDF) + (5,5CPCB) â (2,9CPNDF), with R2 = 0.65 and pe = 1.69.

Abstract:
The objective of this thesis was to evaluate the effect of exogenous enzyme supplementation, phytase and xylanase-glucanase, on AME value of barley in poultry and swine. In the first study, 280 broilers were assigned 1 of 8 treatments. Barley inclusion in the diet resulted in decreased (P < 0.05) performance. There was a treatment × phytase × xylanase-glucanase interaction for dry matter retention with birds fed the corn-SBM-barley diet supplemented with phytase and xylanase-glucanase having higher (P < 0.05) DM retention compared to birds fed corn-SBM-based diet with only xylanase-glucanase supplementation. AME and AMEn of corn-SBM-based diets were greater (P < 0.05) than the corn-SBM-barley-based diets. Energy metabolizability and AMEn of barley significantly increased with xylanase-glucanase supplementation. In the second study, 24 pigs (12 pigs/phase) were assigned to 1 of 4 treatments with xylanase-glucanase and phytase. After a 7-d adaption period, urine and feces were quantitatively collected for 5 d. DE of the barley-based diet supplemented with xylanase-glucanase (3,578 kcal/kg) and phytase and xylanase-glucanase in combination (3,617 kcal/kg) were significantly different. Compared to control diets, exogenous enzymes either significantly improved or had a tendency to improve AME and AMEn value of barley in broilers, but not in growing pigs.

The objective of this study was to evaluate the ingestive behavior, average daily weight gain (ADG), feed conversion (FC), feed efficiency (FE), carcass characteristics, commercial cuts weights and yield, weight of gastrointestinal content and compartments, weight and yield of internal organs of Morada Nova growing lambs fed different levels of metabolizable energy (ME). 32 lambs, non-castrated, with average initial body weight of 12.12 Â 1.69 kg and approximately 60 days of age were used. Animals were distributed into four experimental treatments determined by different levels of metabolizable energy (1.28, 1.72, 2.18 and 2.62 Mcal/kg DM), in a randomized block design with eight replicates per treatment. Tifton 85 hay was used as roughage. Lambs were slaughtered sequentially as the group of animals of each treatment reached an average of 25 kg of body weight. Increasing linear effect was observed of metabolizable energy levels (P<0.05) over dry matter (DM) intake and decreasing linear effect for neutral detergent fiber (NDF) intake, both expressed in g/day, %BW e g/kg0,75. Eating, ruminating and total chewing times, expressed in h/day, decreased linearly (P<0.05) with increasing levels of energy in the rations. Idle time, in turn, increased linearly (P<0.05). Eating and rumination efficiencies were influenced by the energy levels (P<0.05) expressed in g DM/h. The number of ruminal boluses, number of chews and chews per ruminal bolus were not affected by the levels of ME. However, time spent chewing per ruminal bolus was influenced (P<0.05). Increased linear effect (P<0.05) was observed for ADG, without affecting, however FC and FE. Carcass traits such as: empty body weight, hot carcass weight and yield, cold carcass weight and yield, loss by cooling and biological yield were not affected (P>0.05) by the increasing levels of dietary energy. Increased linear effect (P<0.05) was also observed for ribeye area and decreased linear effect (P<0.05) for loss by fasting with the increasing of ME levels. The levels of energy also decreased (P<0.05) the weight of the cuts shoulder and leg (%), and increased linearly the neck (kg), rib, breast and flank expressed in kg and%. There was no effect of energy levels (P>0.05) on weight of gastrointestinal content. Increased linear effect (P<0.05) was observed for the weights of heart, the group of organs lungs, trachea, esophagus and tongue (PTEL), liver and spleen, expressed in kg. Regarding the compartments of the gastrointestinal tract, it was observed increased linear effect (P<0.05) only for rumen-reticulum, in %, and small intestine, in kg. The perirenal, omental and mesenteric fats were also influenced by the energy levels (P<0.05) with linear increase when expressed in kg and %. It was concluded that the increase of ME levels of diets influences the ingestive behavior, promote increases in ADG and ribeye area, and reduction in loss by fasting. Regarding the weights of cuts, levels of ME reduce shoulder and leg and increase neck, rib, chest and flank. Levels of ME also influence positively weight and yield of internal organs, viscera and fats of Morada Nova lambs during the growing period.

Abstract:
The poultry industry has advanced remarkably over the past 30 years. In particular, broiler production has been the most successful than any other sector in the animal industry. Production standards of broilers have continuously improved over this period, with modern broilers reaching a live average weight of 2.5 kg at 33 – 35 days. Today, under normal conditions, a broiler chicken can gain an average weight of 65 g per day and can attain 1.5 feed conversion ratio (FCR). Genetic selection brought about by breeding companies has played a big part in the improvements of broiler growth, and advances in nutritional management have provided about 10 to 15% of these changes. In conclusion, future broiler nutrition studies are going to be continued on the plane of economic criteria, determination of alternative feedstuffs and their cultivation, production of new feed additives, sustainability, and food or product quality. However, broiler nutrition studies are expected to contain not only pure and applied nutrition but also to answer and to enlighten some discussed issues such as to support animal welfare, consumer health, and ecological equilibrium. In this review, the latest improvements in feed formulation with much attention on metabolizable energy (ME) and crude protein (CP), feeding systems and feed presentation, use of feed additives to enhance feed use and broiler performance are discussed.
