The paper presents results of the effect of zeolite supplement Min-a-zel (ITNMS – Institute for Technology of Nuclear and Other Mineral Raw Materials, Belgrade, Serbia) on body weight and total and average daily gain in fattening of beef cattle. The trial involved 22 male beef of domestic spotted breed Simmental type divided into two trial groups. The feeding trial lasted 155 days. A daily ration included fodder (meadow hay) and a compound feed concentrate. The trial group (0-I, n=11) was fed with Min-a-zel through the compound feed at the rate of 0.5% and the control group (C, n=11) was fed with the compound feed having the same composition but without the zeolite supplement. During the trial the beef were weighed on the 1st, 31st, 61st, 91st, 121st and 155th fattening days. Average beef weight at the beginning of the fattening was 142.36 kg/head (C) or 142.45 kg/head (0-I). At the end of the trial, the C group cattle and 0-I cattle achieved an average body weight of 332.54 kg/head and 336.45 kg/head and an average daily gain of 1.23 kg/head/day and 1.25 kg/head/day, respectively. The trial group (0-I) fed with Min-a-zel supplements (0.5%) had higher body weights, higher total gain and increased average daily gain in a trial periods compared to the control (C). the established differences in total gain (3.82 kg/head) and average daily gain (25 g/head/day) between the trial groups at the end of the fattening period were not statistically significant (p is greater than 0.05).
