Collaborative project: Innovative characterisation and improvement of the feeding value of cereal grains (GrainUp) - Subproject 6: Phosphorus availability in broiler chickens and turkeys
Project
Project code: keine Angabe
Contract period: 01.06.2011
- 31.05.2014
Purpose of research: Experimental development
The availability of phosphorus from cereal grains in poultry varies. It is also known that the availability of phosphorus differs between broilers and turkeys. In this project, therefore, standardized measurements for availability of phosphorus will be carried out with both species. Based on the results, estimation methods shall be derived that allow the prediction of the P availability for the two species. In close cooperation with TP5, and following the procedure developed for the pig, the results will be used to develop an in vitro method for estimating the P availability. This requires the data about the P fractions and phytase activity identified in subproject Z. As the same cereal lots are used in TP1 and 2 it can then be assessed whether there are relationships between the P availability and the digestibility of amino acids and starch, respectively, or other fractions that are more important in this context.
