Subject(s): Online resources: In: Egyptian Journal of Desert Research 2008.v.58(1)Summary: A total number of 24 pairs of baladi adult pigeons at the 9th month old (24 females and 24 males) and 24 pairs of squabs (which were hatched from the parents of the squabs), were used in this experiment. Pigeons and squabs were divided into 4 equal experimental groups of 12 adult pigeons (6 females and 6 males). The first group fed diet contained 11% crude protein (CP), while the other three groups fed diets containing 13, 15 and 17 % protein levels and the metabolizable -energy (ME/kg) was 2900 kcal ME/kg. The experimental diets were isocaloric and isofibrous. The experiment aimed to evaluate the effect of different protein levels on the performance of squabing pigeons. Results obtained could be summarized as follows: The final live body weight and body weight change during the whole experimental period decreased not significantly among the different experimental adult pigeons. There were no significant differences between groups during hatchability and incubation periods. All groups had similar values of hatchability percentage and incubation periods. Live body weight and body weight gain were significantly decreased (P<0.05) with the increasing of protein levels in the squabs diets, where the 13% protein level recorded heavier body weight than the other protein levels. Keywords: Protein level, pigeons, squabs, performance, digestion trials, carcass traits.
