initial body weight of pigs were average 27.0 kg. The goal of research was to assess the effect of
replacement of coated barley grain with hulless barley in diet on pig growth, carcass and pork
quality indices. Experimental groups of pigs on the holding were conducted according to age and
sex. For trial group of pigs, a compound feed with hulless barley (38.9–45.4%) was prepared, for
the control with coated barley (39.3–43.3%). The feed recipes made according the pigs age. The
other feed ingredients were not changed and were wheat, soybean meal and oil, premivit, and
from 20 till 70 kg liveweight also fish meal. Diets were formulated with the same of
metabolizable energy and crude protein content. During the study the live weight of pigs was
monitored and the feed consumption was counted. At the end of the study all pigs slaughtered,
determined carcasses traits and took samples of loin muscle for chemical analyses. The results
showed that pig fattening indices (daily liveweight gain were in control pig group 0.686 ± 0.183
and trial 0.716 ± 0.174) did not differ significantly between groups (P > 0.05), although its were
slightly lower in the control group pigs by 4.37%. Feed consumption for live weight gain in both
groups ranged from 3.14 to 3.25 kg. Carcasses scores showed significant differences in lean meat
and chops (P < 0.05). There were also differences in the backfat thickness. The thickness of
backfat was 2.62 mm less in the control pig group, which indicates that when feeding coated
barley to fattening pigs, the carcasses have a higher proportion of lean meat (62.1 ± 0.7%). Pigs
were slaughtered reaching a live weight of 110 to 114 kg. The meat yield 71.7% and moisture
level (70.2–75.2%), as well as protein (22.3–22.9%) indicators showed that fattening pigs are
sold at the optimal age. In conclusion, results from this study suggest that feeding hulless barley
to fattening pigs results in higher live weight gain. Carcass indicators showed a significantly
higher proportion of lean meat and weight of chops when pigs eating coated barley. Chemical
