Microbial phytase supplementation for improving availability of plant phosphorus in the diet of the growing pigs
1990
Matti Näsi
The effect of a phytase supplement produced by Aspergillus niger on phytinphosphorus availability for pigs on phytase deficient maize-soybean meal diets was measured in two digestibility and balance experiments involving twelve growing pigs. Apparent digestibility of P in diets without inorganic-P supplementation or with low addition (0.18 of total P) was significantly lower than in the control diets (0.16 and 0.23 vs. 0.42; P
