The utilization of phytate-phosphorus by the transition dairy cow
<p>Phytate phosphorus (pP) availability in rumen fluid was analyzed during the transition period of two heifers by in vitro and in situ incubations. Apparent digestibility (AD) of P during the transition period was measured and P balance determined. The study included three periods, a prepartum …

Evaluation of Methods for Improving Phytate Phosphorus Utilization in Poultry and Swine
… not increase amino acid availability in several phytate-containing ingredients as assessed by a PER assay.

Effects of dietary calcium to non-phytate phosphorus ratio and phytase supplementation on growth performance, digestibility, and bone characteristics of broiler chickens
… to evaluate the interrelationships among Ca, non-phytate phosphorus (NPP), and phytase supplementation in diets fed to broiler chickens. Experiment 1 was conducted to evaluate the influence of dietary Ca concentrations by evaluating growth performance, tibia measurements, and apparent retention of …

Inheritance of Soluble Oligosaccharides in Soybean Seeds
… relationship was observed between inorganic phosphorus and stachyose content of soybean seeds but a relationship was not observed between stachyose and phytate phosphorus or between inorganic phosphorus and phytate phosphorus.

FACTORS AFFECTING THE AVAILABILITY OF IRON IN WHEAT BRAN AND PEA BRAN
… diet was fortified with K2HPO4 to provide a phosphorus content similar to that in the wheat bran diets. The a-cellulose and white flour diets were fortified with 18 ppm iron as ferrous sulfate. The bioavailability of iron was evaluated by comparing the hemoglobin-iron gain per intake of iron …

Protein Utilization and Requirements in Broiler Breeders
… In the final two studies, the effects of low non-phytate phosphorus (NPP) on the diurnal patterns of bone turnover and the effects of carnitine supplementation on the fatty acid profiles of a hen and her eggs. Lowering NPP to 0.15% was found to diminish the amount of bone that is mobilized in an …

The effects of various concentrations of phytase on broiler growth performance, phosphorus digestibility, tibia ash, and phosphorus utilization
… broiler growth performance, carcass composition, phosphorus digestibility, tibia ash and phosphorus utilization. The first experiment contained a positive control (PC) diet that was sufficient in all nutrients, a diet reduced in available phosphorus, calcium, amino acids and energy utilized as a …

Strategies to maximize feed quality and poultry performance
… and subsequent immune response caused by phytate phosphorus (P); therefore, other objectives of research conducted in Chapter 5 were to assess the effect of increasing phytase inclusion on D40 gut inflammation via ileal mRNA expression of Interleukin (IL)-1beta and IL-6, and D40 total P …

Quantification and alleviation of the antinutritional effects of phytate on poultry
The phosphorus (P) requirements of meat-type poultry cannot be met by plant-based diets because approximately two thirds of total phosphorus in cereals and leguminous feed materials is in the unavailable form of phytate (inositol hexaphosphate or phytic acid). Phosphorus supplements are expensive …

Digestion of inositol phosphates by dairy cows: Method development and application
… is not possible without a reliable and accurate phytate (Pp) quantification method. The objective of the first study was to develop a robust, accurate, and sensitive method to extract and quantify phytate in feeds, ruminant digesta and feces. Clean-up procedures were developed for acid and …
