In modern poultry production, newly hatched chicks have no contact with maternal feces and so no maternal spectrum of antigens is present. In this situation, chicks can be affected by a number of pathogenic intestinal microorganisms, and fortifying diets with prebiotics can alleviate this problem. This study was carried out to determine the effect of dietary supplementation of Aspergillus meal prebiotic (Fermacto®) on performance, carcass characteristics and some blood parameters of Chukar partridge (Alectoris chukar chukar). A total of eighty day-old mix sex chicks with similar average weight were used in a completely randomized design in this experiment. They were divided into 1 control and 1 experimental group and each group was further divided into 4 subgroups of 10 chicks each. The experimental period lasted 16 weeks in two phases of starter (0-8 weeks) and grower (9-16 weeks). Control group was fed with unsupplemented and experimental group with supplemented (1.8 gkg-1 Fermacto®) basal diet in each phase. Data revealed that supplementation of Fermacto® in meat-type partridge diet resulted in significant (p<0.05) higher breast and gastrointestinal tract percentage, lower back-neck percentage, decreased triglyceride and total cholesterol and increased calcium level of serum than those the control group. The effect of Fermacto® supplementation to diet on body weight gain, live body weight, cumulative feed consumption, cumulative feed conversion ratio, carcass characteristics (carcass, legs, wings and feet) and blood parameters (glucose and phosphorus) of meat-type partridge were not statistically significant among the groups (P>0.05). This could be attributed to low level treated of Fermacto® and optimal and hygienic environmental and management conditions. Likewise, game birds (quail, partridge, pheasant and …) may have better potential of advantageous microflora in their gut than the domestic poultry due to their longer contact with a variety of microorganisms in wildlife.
