Forme d'apport du phosphore, performances et minéralisation osseuse chez le poulet de chair

Abstract : In poultry farming, meeting the requirements in phosphorus and calcium of the animals is essential. Phosphates are among the most interesting forms of intake. It is important for a firm providing services in animal nutrition to have a correct matrix of formulation for its raw materials. The objective of this work was the validation of the MG2MIX matrix for two phosphates: DFP phosphate and Neophos phosphate, with dicalcium phosphate used as a control. A trial was conducted in an experimental station on 3048 Ross PM3 broiler strain allocated in 24 boxes. Three diets, chosen to be identical in terms of nutrient intake, were tested. The animal weights were recorded at 10, 21 and 34 days of age. Tibias of 8 chickens per diet were collected at 22 and 34 days and analyzed. None significant difference between diets for growth performance or bone mineralization were shown. The matrix was approved despite the significant effect of the diet for two variables studied: ADG between 10 and 21 days and tibial stiffness at 22 days. This last result should be taken with caution because of the small number of replicates per treatment for bone data.
