Minerals in poultry nutrition

Minerals in poultry nutrition are typically classified as macro- or micro-minerals, depending on the levels needed in the diet. The macro-minerals include calcium, phosphorus, chlorine, magnesium, potassium, and sodium. Requirements for the macro-minerals are typically expressed as a percentage of the diet, while the requirements for the micro-minerals are stated as parts per million. Although the quantities required for micro-minerals are lower than for macro-minerals, they play an essential role in the body's metabolism. The micro-minerals include copper, iodine, iron, manganese, selenium, and zinc.

Improving phosphorus availability in broiler diets based on wheat-soybean meal using microbial phytase produced in solid state fermentation

Phytic acid is abundant in all plant seeds serving as the chief storage form of phosphorus (P). The phytic acid molecule has a high P content (28.2%); and since a major portion of poultry and pig diets consists of plant-derived ingredients, P from the phytic acid assumes considerable nutritional significance. The ability of poultry and pigs to utilise phytate P is poor (Nelson, 1967; Ravindran et al., 1995; Kornegay, 1999) due to either insufficient quantity or a lack of intestinal phytase...
