Dose-dependent effects of a microbial phytase on phosphorus digestibility of common feedstuffs in pigs
OBJECTIVE The objective of this study was to evaluate increasing doses of a novel microbial phytase (Cibenza Phytaverse, Novus International, St. Charles, MO, USA) on standardized total tract digestibility (STTD) of P in canola meal (CM), corn, corn-derived distiller's dried grains with solubles (DDGS), rice bran (RB), sorghum, soybean meal (SBM), sunflower meal (SFM), and wheat. METHODS Two ...
متن کاملEffect of microbial phytase on apparent digestibility and retention of phosphorus and nitrogen in growing pigs
Six female pigs of approximately 50 kg BW, fitted with simple T-cannula in the terminal ileum, were used to study the effect of microbial phytase on apparent total tract digestibility and retention of P and N. Three P-adequate diets (digestible P concentration 2.3 g/kg) containing barley (B), soybean meal (S) or their mixture (BS) with or without phytase supplement (1 000 FTU/kg) were fed to pi...
متن کاملGrowth Performance, Phosphorus Balance, and Bioavailability of Phosphorus in Pigs Fed High Available Phosphorus Corn and Phytase
Phytase has been shown to consistently improve the bioavailability of phytate phosphorus for pigs. However, only about 60 to 70% of the phytate P in a corn-soy diet is made available when supplemented with an optimal phytase dose. The use of high available P (HAP) should provide an additional strategy for improving the bioavailability of phytate P in pigs. In experiments 1 and 2, growth perform...
متن کاملEffects of formic acid and phytase supplementation on digestibility and use of phosphorus and zinc in growing pigs.
Two studies, arranged according to a 4 × 4 Latin square design, were conducted to assess effects of dietary acidification on fungal 3-phytase (PHY) efficacy in growing pigs. In Exp. 1, effects of supplementing 500 units/kg feed of PHY and 4.7 g/kg HCOOH either alone or in combination on the use of P and Zn in growing pigs fed a pelleted diet based on wheat (Triticum aestivum), barley (Hordeum v...
متن کاملTrue digestibility of phosphorus in canola and soybean meals for growing pigs: influence of microbial phytase.
Two studies with growing pigs were conducted using the regression analysis technique to estimate the true digestibility of P (TPD) in canola (CM) and soybean (SBM) meals, and quantify the effect of microbial phytase on TPD of CM and SBM. In each study, 48 (Exp. 1) or 36 (Exp. 2) 17-kg barrows were assigned to 6 dietary treatments arranged in a 3 x 2 factorial of 3 graded levels of CM (Exp. 1) o...
