I. INTRODUCTION Dietary electrolyte balance (DEB) is defined by the interrelationship between sodium (Na+), potassium (K+) and chloride (Cl-) where DEB = Na++K+ -Cl- as mEq/kg and it plays an influential role in homeostasis of the body fluids. Borges et al. (2004) investigated DEB in two experiments and concluded that there was a quadratic effect on weight gain and feed conversion efficiency (FCE ...

I. INTRODUCTION Crude protein-reduced broiler diets have the potential to provide tangible advantages in respect of economics, bird welfare, flock health and the environment. Moderate reductions in dietary crude protein (CP) levels can be achieved without compromising broiler performance when coupled with judicious synthetic amino acid inclusions. However, there appears to be a threshold where fu ...

Accurate estimation of the broiler’s lysine (Lys) requirement is vital because it is the second limiting amino acid (AA) in poultry diets and, when the ideal protein ratio concept is applied, the essential amino acids (EAA) are expressed as ratios to Lys. It is necessary to regularly update AA requirements for modern broiler chickens in order to accommodate their genetic progress. However, d ...

I. INTRODUCTION The feed efficiency (FE) of commercial laying hens has improved steadily since genetic selection began in earnest, with modern hybrids converting approximately 2.1 kg of feed into 1 kg of eggs. Recent research suggests considerable variation in FI and FE between hens kept under common management and dietary conditions (Akter et al., 2018). Research also indicates that many factors ...

I. INTRODUCTION Exogenous phytase improved ileal amino acid digestibility by an average of 5% based on 745 observations across 24 studies in a systematic review (Cowieson et al., 2017). Nevertheless, the post-enteral availability of amino acids is ultimately determined by their transition across enterocytes in the gut mucosa. Amino acids may be denied access to the portal circulation because the ...

Both glucose and amino acids are essential for muscle protein deposition and feed conversion efficiency. Total tract nitrogen retention was reported to be influenced by protein and starch digestion in broiler chickens (Liu et al., 2013). Embracing the concept of digestive dynamics and applying it in practical diet formulation requires understanding of the variations of protein and starch digestion ...
