Understanding the dynamics of calcium (Ca) and phosphorus (P) metabolism is an important consideration when evaluating the requirements for both nutrients. Much more is known about the control of Ca than P metabolism (Li et al., 2017). Calcium elimination from the body is primarily through faeces, both unabsorbed dietary Ca and endogenous Ca. Kidney Ca elimination is controlled by endocrine factor ...

Phytase supplementation of broiler diets can improve energy, amino acid, calcium (Ca) and phosphorus (P) utilization. Both fungal- and bacterial-derived phytases are commonly added to broiler diets. Phytases from different sources and even from the same source can have different pH optima, heat stability, and catalytic properties (Dersjant-Li et al, 2015). Furthermore, when different microbial phy ...

Probiotics are showing promise as antibiotic replacements but more scientific evidence is required to validate their beneficial effects. Previous broiler feed trials conducted with Bacillus amyloliquefaciens strain H57 (H57) indicated variable bird performance (Bajagai, 2018). In these trials, birds were kept under “optimal” experimental conditions, where most of stressors were absent ...

Canola and camelina meals have been identified as alternative plant protein sources in place of soybean meal for animal feeding. The use of these protein sources at high inclusion levels is limited due to the presence of antinutritional factors such as phytic acid, glucosinolates, erucic acid, sinapines and tannins which have negative effects on production performance of broiler chickens (Thacker ...
