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 (Pleurotus species) has
significant amount of phytase activity and in this study it was
found that supplementation of oyster mushroom to pig ration had
significantly improved P utilization.
