The effect of dried yogurt (Kashik) based on Lactobacillus plantarum and Lactobacillus acidophilus on broiler meat crude protein and fat content and tibial bone mineral composition was studied. The birds were fed diets including probiotics only during the first 21 days of age. The trial groups T1, T2 and T3 were supplied with 1, 3 and 5 % yoghurt, respectively. The control group was fed with a commercial feed mixture. Breast muscles nutrition quality was not significantly affected with Kashik up to day 21. The highest difference was 0.25% (C and T3) in crude protein concentration and 0.15% in crude fat (C and T2). Leg muscles crude protein and fat percentages were not affected by probiotics up to day 21 of age. The values varied from 18.76 to 19.24% and from 5.77 to 6.54%, respectively. However, significant differences in legs' muscles crude protein (19.05 and 19.92% in C and TI group) and fat concentrations (4.82 and 6.33%) were observed between the T1 and T3 group up to 40 days of age. No significant effects of probiotics were observed on breast muscles mineral content up to 21 days and 40 days of age. Leg muscles mineral levels were not affected with probiotics up to 21 days, whereas up to 40 days only leg muscles P and Mg concentrations were affected (1.80 and 1.61 g/kg of P in C and T3 group and 0,42 and 0,44 g/kg of Mg in C and T1 group, resp.). There were no significant effects of treatments on tibial bone Ca and Mg levels up to day 21. However, tibial bone P content was significantly affected. The addition of 3 and 5 percents of Kashik increased tibial bone P content significantly (98.5 g/kg in T2, 97.0 g/kg in T3) above the value of the control group (80.5 g/kg) up to 21 days of age. There were no significant differences between treatment groups and the control group in tibial bone P and Mg composition at day 40 of age. The values varied from 86.00 to 93.12% in C and T1 in P and 4.10 to 4.23 g/kg in Mg concentration. Some significant differences were observed between the treatment group which was supplemented with 1% of Kashik and the control group in tibial bone Ca composition at day 40 of age (213.62 and 229.06 g/kg, resp.).
