FATTY ACID PROFILE AND APPARENT METABOLIZABLE ENERGY OF DIFFERENTS LIPID SOURCES FOR LAYING HENS

Abstract

It is important to determine the current nutritional values of ingredients for the practice of feed formulations. The objective of this research is to determine the fatty acid profile and evaluate the apparent metabolizable energy (AME) and the AME corrected for nitrogen balance (AMEn) for laying hens of the following types of oils: soybean, sunflower, linseed and fish. Thus, a completely randomized design with four treatments and seven replicates with eight birds each will be used. The treatments will be: T1 - basal diet + 10% soybean oil addition, T2 - basal diet + 10% sunflower oil addition, T3 - basal diet + 10% linseed oil and T4 - basal diet + 10% fish oil. The fatty acid profile of lipid sources will be analyzed by gas chromatography. The digestibility trial will be held by the total excreta collection method, using 280 birds and 35 experimental cages, including the birds of the control group will receive only the basal diet. The results will be statistically analyzed with criteria of 5% probability. The metabolizable energy values of lipid sources will be submitted to analysis of variance (ANOVA), and when necessary, the treatment means will be compared by Tukey test. (AU)
