All grains, vegetable-based protein meals and their by-products used in poultry diets contain some levels of phytate phosphorous (PP). Depending on the ingredient type and source, a typical broiler chicken diet would contain between 2.2 to over 3.5 g/kg dietary PP. Research has shown that phytate anti-nutritional effects can reduce the digestibility of amino acids (AA) and minerals. Previously the ...

An organic mineral is a combination of a metal ion with an organic molecule called ‘ligand’ such as amino acids, proteins, polysaccharides, yeast, or organic acids. Specifically, the metal ion is bound to the organic ligand through multiple attachments (either ionic or covalent) with the metal ion occupying a central position in the structure (Kincaid, 1989, Nelson, 1988).Animal Trace ...

The occurrence of pasty vent is usually observed after 3 days of age when chicks are mainly depending on their feed rather than their yolk sac. Some chicken flocks present pasty vent more often than others, being their frequency variable and hard to track. How can it be prevented or treated? Could this characteristic damage the growth or feed conversion ratio at the market age? The pasty vents are ...

BackgroundThe avian ceca generally have a more important role in digestion than the cecum in most mammals. Avian ceca are usually finger-shaped blind pouches, presenting as lateral extensions at the junction of the small and large intestine and are commonly present in pairs. In birds the ceca vary considerably in size and morphology; ranging from very long, such as in most domestic poultry, to com ...
