Açaí meal on diet digestibility for commercial laying hens Animal Sciences
Rufino, João Paulo Ferreira; Cruz, Frank George Guimarães; Dias, Fábio Jacobs; Brasil, Ronner Joaquim Mendonça; Silva, Ana Rebeca Pires da; Melo, Paloma Leandra Garcia.
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...

Committee neural network and weighted multiple regression to predict the energetic values of poultry feedstuffs PAB
Mariano,Flávia Cristina Martins Queiroz; Lima,Renato Ribeiro de; Alvarenga,Renata Ribeiro; Rodrigues,Paulo Borges.
Abstract: The objective of this work was to compare the committee neural network (CNN) and weighted multiple linear regression (WMLR) models, in order to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) of poultry feedstuffs. The prediction equation was adjusted by using a WMLR model and the meta-analysis principle. The models were compared by considering the correct prediction percentages, based on the classic prediction intervals and on the highest-probability density intervals, and by using a comparison test for proportions. The accuracy of the models was evaluated based on the values of the mean squared error, coefficient of determination, mean absolute deviation, mean absolute percentage error, and bias. Data from metabolic trials...
