| ABSTRACT The objective of this study was to evaluate the standardized ileal digestible (SID) valine and SID leucine levels on performance, backfat thickness, longissimus dorsi depth, and biochemical blood parameters of starting gilts. A total of 72 gilts, with initial weight of 15.16±1.15 kg, were distributed in a randomized block design in a 2 × 4 factorial scheme, comprised of two SID leucine levels (1.20 and 1.77%) and four SID valine levels (0.58, 0.73, 0.88, and 1.03%), with nine replicates and one animal per experimental unit. No interactions were observed for growth performance parameters. Final weight and average daily gain presented linear and quadratic effects. Setting data to the quadratic model associated with the Linear Response Plateau model,... |

| ABSTRACT The present study aimed to determine the apparent metabolizable energy (AME) of six corn cultivars, two sorghum cultivars and two wheat brans and to evaluate the cross-validation of predictive models of AME for corn, sorghum and wheat bran for growing pigs, as estimated from the data of chemical composition. Forty-four pigs, with an average initial weight of 24.3 kg, were distributed in a randomized block design, with 11 treatments (ten food treatments and the reference diet), four replicates and one pig per experimental unit. The reference diet was replaced by 30% for the ground corn and sorghum conditions and 20% for the wheat bran condition. The values of AME for corn, sorghum and wheat meal for pigs ranged from 3161 to 3275, 3317 to 3457 and... |

| RESUMO Este trabalho teve por objetivo determinar a composição bromatológica, energética e a digestibilidade ileal de aminoácidos do resíduo seco de destilaria com solúveis (DDGS), além de avaliar o efeito da utilização desse resíduo sobre o desempenho e rendimento de carcaça de frangos de corte dos 22 aos 42 dias de idade. No primeiro experimento, foram utilizadas 48 aves Cobb, machos, com 21 dias de idade e peso médio de 932 g ± 45 g, distribuídas em delineamento experimental inteiramente casualizado (DIC), com dois tratamentos, seis repetições e quatro aves por unidade experimental. No segundo (digestibilidade dos aminoácidos), foram utilizados 12 galos Leghorn cecectomizados, com peso médio de 1.912,1 ± 133,73 g, distribuídos em DIC, com um alimento... |

| ABSTRACT The use of predicted values of apparent metabolisable energy (AME), obtained from regression equations, can be useful for both research institutions and nutrition industries. However, there is a need to validate independent samples to ensure that the predicted equation for AME is reliable. In this study, data was collected in order to estimate the prediction equations of corn, sorghum and wheat bran for pig feed, based on the chemical composition, in addition to evaluating the validity of the stepwise selection procedure regressive method of non-parametric bootstrap resampling. Data from metabolism trials in pigs and the chemical composition of feedstuffs was collected from both Brazilian and international literature, expressed as dry matter.... |

| RESUMO Foram utilizados 1200 pintos da linhagem Label Rouge, com peso médio inicial de 41,0 ± 0,55 g, distribuídos em um delineamento inteiramente casualizado, em esquema fatorial 2 x 5, (com e sem acidificante X 0, 25, 50, 75 e 100% de silagem de grãos úmidos de milho - SGUM). Foram determinados o ganho de peso (GP), consumo de ração (CR), conversão alimentar (CA), além da análise morfométrica e de microbiota intestinal, rendimento de carcaça e de cortes. De 1 a 63 dias, houve efeito quadrático (P<0,05) da SGUM sobre o CR e CA. Houve interação (P<0,05) entre os níveis de SGUM e a adição de acidificante para o rendimento de carcaça, e de cortes (asa e peito) e fígado das fêmeas. Os machos apresentaram interação (P<0,05) entre os níveis de SGUM e o... |

| The ideal protein concept for pigs has allowed reducing levels of crude protein in the diet, since synthetic amino acids are included because the branched chain amino acids may be limiting. In order to determine the digestible isoleucine requirement for gilts from 15 to 30 kg, a performance assay was accomplished, using 40 crossbreed gilts of high genetic potential, averaging 15.00 ± 0.52 kg of body weight, alloted in a randomized blocks design, consisting of five treatments (0.45, 0.52, 0.59, 0.66, 0.73% of digestible isoleucine), four replicates and two animals per experimental unit. Performance traits were determined and at the end of the experiment one animal per experimental unit was slaughtered to determine carcass composition and organs weight.... |

| ABSTRACT Corn is one of the primary ingredients in swine diets, but there is a variation in its chemical composition and metabolizable energy (ME) content. Therefore, faster methods are required that can determine more accurate ME values to improve piglet diets. This study determined and predicted the ME of corn from first and second harvests for piglets. Two experiments were conducted to determine the ME values for 18 corn batches, evaluating corn from first and second harvests. The corn batches were analysed to determine the concentration of dry matter (DM), starch (ST), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), ether extract (EE), ash, calcium (Ca), phosphorus (P) and gross energy (GE). To determine the ME values, 40... |
