Abstract
A total of 180 Japanese quail chicks at one day-old were used in an experiment, which lasted 6 weeks. The experiment aimed to study the utilization of date stone meal (DSM) as agro-industrial by-products by feeding growing Japanese quail.
Quail chicks were divided into 4 equal experimental groups of 45 chicks each.
Every group was sub-divided into three replicates (15 chicks/ rep.). The first group was fed the basel diet as a control (0% DSM), while, the other three groups were fed diet containing 5,10 or 20% DSM. The experimental diets were isocaloric and isonitrogenous .
Results obtained could be summarized as follows:
Live body weight, body weight gain and feed intake were significantly (P<0.05) decreased with the increasing of DSM % in the diets. Moreover, feed conversion ratio (g feed/g gain) became significantly worst (P< 0.05) by increasing DSM up to 20% in the diets.
Digestion coefficients of CP, CF and NFE % were significantly decreased by increasing DSM in the diets. However, digestion coefficient of EE was not significantly influenced by the different levels of DSM. Different levels of DSM in diets caused significantly (P< 0.05) decreases in dressing percentage with the increase of DSM up to 20% The 10 % DSM level showed the best net return as well as the highest value of economic efficiency among all experimental groups. Serum TP, AL, GL, AlG ratio, Cr and Ur recorded a non-significant difference between quail groups. Serum AL T, AST enzymes recorded an increase (p < 0.05) with increasing O!:>M levels, and however cholesterol level decreased.
From the nutritional and economical efficiency stand points of view, the date stone meal could be recommended to be used successfully and safely in formulating diets for growing quail, if included up to 10% without adversely affecting their growth performance or physiological parameters.
