Availability of Phytic Acid Phosphorus for Chick

Hydrolysis of phytic acid and its availability in rabbits.

Twenty weaned rabbits were fed ad libitum two granulated feeds containing lucerne meal, barley, oats, wheat bran, oilseed meals and sugarbeet pulp in different proportions. Phytate P in these feeds represented 28.6 and 29.3 % of the total P. Digestibility trials were carried out in rabbits 7 and 10 weeks old. Digestibility of phytate P was 82.1 %, on average. Apparent digestibility of total P w...

Overexpression of a Gene Involved in Phytic Acid Biosynthesis Substantially Increases Phytic Acid and Total Phosphorus in Rice Seeds.

The manipulation of seed phosphorus is important for seedling growth and environmental P sustainability in agriculture. The mechanism of regulating P content in seed, however, is poorly understood. To study regulation of total P, we focused on phytic acid (inositol hexakisphosphate; InsP₆) biosynthesis-related genes, as InsP₆ is a major storage form of P in seeds. The rice (Oryza sativa L.) low...

The availability to the chick of pantothenic acid in foods.

1. The content of total pantothenic acid (PaA) in two foodstuffs of microbial origin was measured by standard microbiological and chick biological assays. 2. Substantially and consistently higher values were found by the chick assay than by the microbiological determination, indicating that PaA-containing compounds were present that were not utilized by the test micro-organisms but were availab...

effect of oxalic acid on increasing soil phosphorus availability for wheat

most plants are able to increase soil phosphorus availability by exuding some compounds such as organic acids when they experience phosphorous deficiency. considering this special ability of plants, the main purpose of the present research was to investigate if application of organic acids may increase p availability in soil. therefore, a greenhouse experiment was conducted with five treatments...
