Commercial laying hen diets formulated according to different recommendations of total and digestible amino acids

Substitution of soybean with canola meal in laying hens diets formulated based on total and digestible amino acids on performance and blood parameters

An experiment was conducted to study the effects of substitution soybean meal (SBM) with canola meal (CM) and formulated diets based on total and digestible amino acid on performance, egg quality, organs weight and blood parameters of laying hens from 73 to 83 weeks of age. A total of 128 laying hens were distributed by completely randomized design in a 2×2 factorial arrangement with 2 protein ...

The effect of substitution of soybean with canola meal in laying hen diets formulated on the basis of total or digestible amino acids on performance and blood parameters

An experiment was conducted to study the effect of substitution of soybean meal (SBM) with canola meal (CM) in diets formulated on the basis of total or digestible amino acid (AA) on productive performance, egg quality, and selected organ weight and blood parameters in laying hens from 73 to 83 weeks of age. A total of 128 laying hens were allotted randomly to a completely randomized design arr...

Lipid supplementation of laying hen diets deficient in protein and sulphur amino acids

Effects of Lysine Levels of Diets Formulated Based on Total or Digestible Amino Acids on Broiler Carcass Composition

The study was conducted to evaluate carcass yield and chemical composition of thigh and breast muscles of broilers fed three different lysine requirement levels: high lysine (+10% NRC), standard (NRC) and low lysine (-10% NRC) and two ways of expressing amino acids in feedstuffs (total or digestible amino acids). The results of this study showed that diet formulation based on digestible amino a...

Requirement of Digestible Sulfur Amino Acids in Laying Hens Fed Sorghum- and Soybean Meal-Based Diets

Two experiments were done to evaluate the effect of increasing levels of dietary digestible methionine (Met) and Met:cysteine (Met:Cys) ratio on the productivity of Hy-Line W-36 laying hens fed sorghumand soybean meal-based diets. In Exp. 1, 160 hens from 68 to 75 weeks of age were assigned to four dietary levels of digestible Met (0.20 0.24, 0.28 and 0.32%). The digestible total sulfur amino a...
