The aim of the experiment was to monitor the effect of propolis extract on selected parameters of mineral profile (calcium, phosphorus, magnesium, potassium, sodium, chlorides) of Hubbard JV chickens. Chickens were divided into five groups (C, control; E1 – E4, experimental groups). Experimental chickens (n=10 in each group) received propolis in feed mixture in various doses as follows: E1 – 150 mg.kg-1; E2 – 450 mg.kg-1; E3 – 600 mg.kg-1; E4 – 800 mg.kg-1. Feeding period lasted 42 days. Propolis preparation caused a significant (P<0.05) decrease of serum phosphorus and magnesium content. Other parameters were not influenced (P>0.05) after propolis treatment.
