Nutrition is one of the top priorities in pig farming and cost of feed accounts 60 to 80% of the total cost of production. Phosphorus (P) is the third most expensive nutrient in a pig diet, following energy and lysine. P availability is high in animal ingredients but it is remarkably low in plant ingredients as around 75% of the total P is bound to phytate. Phytate is an anionic compound having anti-nutritional effect on P availability to monogastric animals like pig. It also depress the activity of digestive enzymes, bind to dietary proteins and amino acids, and form calcium-phosphate-phytate complexes with carbohydrate. The enzyme phytase is chemically known as myo-inositol (1,2,3,4,5,6) hexakisphosphate phosphohydrolase and catalyze the sequential release of P from phytate and make it available to pig and other monogastric animals and reduce P pollution from animal waste like in intensive pig production. It is also increases availability of amino acids in feeds. Oyster mushroom...
