Bone traits and gastrointestinal tract parameters of piglets fed cholecalcifero...
Trautenmüller,Heloíse; Genova,Jansller Luiz; Faria,Adriana Bulcão Bock de; Martins,Juliana Stocco; Viana,Sthefany Caroline MarquesABSTRACT The objective of this study was to evaluate the cholecalciferol and 1,25-dihydroxycholecalciferol glycoside supplementation in piglet diet on organ biometry and physicochemical composition, pH of the digestive tract contents, and bone traits. A total of 128 entire male piglets (21 days-old, 6.82±0.38 kg body weight) were distributed in a completely randomized block design with eight replications and fo...
Metabolisable energy prediction in energy feedstuffs and evaluation of the step...
Oliveira,Newton Tavares Escocard de; Pozza,Paulo Cesar; Castilha,Leandro Dalcin; Pasquetti,Tiago Junior; Langer,Carolina NataliABSTRACT 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 fo...
Metabolizable energy in energy food for growing pigs and cross-validation regre...
Oliveira,Newton Tavares Escocard de; Pozza,Paulo Cesar; Castilha,Leandro Dalcin; Pasquetti,Tiago Junior; Langer,Carolina NataliABSTRACT 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 bl...
The requirement of valine for gilts in the initial phase is not influenced by m...
Huepa,Laura Marcela Diaz; Castilha,Leandro Dalcin; Ferreira,Silvia Letícia; Monteiro,Alessandra Nardina Trícia Rigo; Costa,Alcides Emanuel Rodrigues daABSTRACT 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...
Resíduo seco de destilaria com solúveis (DDGS) na alimentação de frangos de cor...
Schone,Rodrigo André; Nunes,Ricardo Vianna; Frank,Rafael; Eyng,Cinthia; Castilha,Leandro DalcinRESUMO 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 p...
Predicting the metabolizable energy of first and second corn harvests for piglets
Esteves,Lucas Antonio Costa; Oliveira,Newton Tavares Escocard de; Huepa,Laura Marcela Diaz; Ferreira,Silvia Letícia; Castilha,Leandro DalcinABSTRACT 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 value...
Desempenho e parâmetros intestinais de frangos Label Rouge recebendo silagem de...
Frank,Rafael; Nunes,Ricardo Vianna; Schone,Rodrigo André; Parra,Angela Poveda; Castilha,Leandro DalcinRESUMO 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 ...
Levels of digestible isoleucine on performance, carcass traits and organs weigh...
Castilha,Leandro Dalcin; Pozza,Paulo Cesar; Nunes,Ricardo Vianna; Lazzeri,Doglas Batista; Somensi,Marcelo Luiz; Pozza,Magali Soares dos SantosThe 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, all...
