The objective of the experiment was to examine the effect of phytase addition on absorption and apparent digestibility of P when a maize-soyabean meal-based diet was supplemented by different levels of inorganic phosphate. An isotope (32P) metabolic experiment was carried out on crossbred barrows (initial BW of 15-18 kg). The dietary treatments were arranged in a 2 × 2 factorial design with two levels of total P (A:0.67 and L:0.59%) having different levels of P bioavailability (A:0.36 and L: 0… Expand

Effects of level of supplemental phytase on ileal digestibility of amino acids, calcium, and phosphorus in dehulled soybean meal for growing pigs.
TLDR
In this study, supplemental microbial phytase did not improve the utilization of AA provided by soybean meal but was an effective means of improving Ca and P utilization by growing swine fed soybean Meal-based diets. Expand
Digestibility of nutrients in growing–finishing pigs is affected by Aspergillus niger phytase, phytate and lactic acid levels: 2. Apparent total tract digestibility of phosphorus, calcium and magnesium and ileal degradation of phytic acid
TLDR
It is hypothesized that lactic acid delays gastric emptying, which prolongs the action of phytase in the stomach at its optimum pH, and increases the ATTD of total P to a greater extent than was calculated as the sum of the stimulating effects of the single additions. Expand
Digestibility of nutrients in growing–finishing pigs is affected by Aspergillus niger phytase, phytate and lactic acid levels: 1. Apparent ileal digestibility of amino acids
TLDR
It was concluded that when diets are supplemented with either phytase or lactic acid, AID of amino acids is improved, however, supplementing both did not result in a further increase in AID. Expand
Inevitable losses of phosphorus in pigs, estimated from balance data using diets deficient in phosphorus.
TLDR
It is concluded that under the conditions of suboptimal P supply the utilisation of digestible P is almost complete and daily inevitable urinary losses of P depend on body weight and, on average, amount to 0.35 mg/kg BW. Expand
Removal of phytate from soy protein
Phytate, as a minor constituent of soybeans, has been reported to interfere with the dietary mineral absorption of mammals. Commercial soy protein isolate contains 2-3% tightly bound phytate.Expand
