Growth Performance of Growing Pigs Fed Crude Protein-Adequate or Deficient, Low Phosphorus Diets with Graded Levels Of Phytase
نویسنده
چکیده
Nitrogen and phosphorus are the nutrients that are potential environmental pollutants when excessive quantities are applied to soils (Jongbloed and Lenis, 1998). These nutrients are excreted as a consequence of normal metabolic processes, but dietary excesses lead to increased manure excretion. Exogenous phytase (PT) as a dietary additive is widely accepted as an effective strategy for reducing manure P excretion by pigs. There have been conflicting reports as to the efficacy of PT for improving N or amino acid digestibility and retention.

Efficacy of low-activity, microbial phytase in improving the bioavailability of phosphorus in corn-soybean meal diets for pigs.
Two experiments involving 115 pigs were conducted to assess the efficacy of a microbial phytase (Allzyme Phytase; Alltech, Nicholasville, KY) produced by Aspergillus niger in low-P, corn-soybean meal-based diets. The phytase supplement contained 50 phytase units/g and 1.43% P. In Exp. 1, growing-finishing pigs were fed fortified corn-soybean meal diets formulated to be adequate (.50%) or inadeq...

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...

This experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (CA) in canola meal-based diets severely limited in available phosphorus (Pa) on growth performance, plasma phosphorus (P), and tibia ash (TA) in broilers from 22 to 42 d of age. Two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. The exper...

Three experiments involving 162 pigs were conducted to assess the efficacy of phytase (Natuphos; BASF, Mount Olive, NJ) in low-P, corn-soybean meal-based diets. The phytase was produced by a recombinant Aspergillus niger. The phytase supplement contained 5,000 phytase units (PTU)/g. In Exp. 1 (66 pigs) and 2 (60 pigs), growing-finishing pigs were fed fortified corn-soybean meal diets formulated...
