NUTRITIONAL STUDIES ON PHOSPHORUS METABOLISM FOR GROWING RABBITS
HALA MOHAMED GAMAL EL-DIEN;
Abstract
The purpose of the present study is to investigate the effect of different levels and sources of phosphorus on the growing rabbit performance for 7 weeks. One hundred and forty four growing rabbits divided into 12 treatments under sub-four main groups were used:
1- Rabbits fed on organic phosphorus from plant origin.
2- Rabbits fed on organic phosphorus + phytase.
3- Rabbits fed on inorganic phosphorus from dicalcium phosphate.
4- Rabbits fed on inorganic phosphorus from Phosphoric acid. All with the same P levels of 0.45, 0.55 and 0.65%.
Results obtained showed that rabbits fed on 0.45% P
level from organic phosphorus gave better performance and utilized their feed more efficiently.
Adding phytase didn't improve rabbit performance. Phosphoric acid gave the worest results.
