The Effect of the Humic Substances and Thyme on Carcass Parameters of Broiler Chickens

Henrieta Arpášová, Veronika Pistová, Cyril Hrnčár, Martin Fik


The aim of this experiment was to determine the influence of humic substances or humic substances and thyme on carcass parameters of broiler chickens. A total of 60 Ross 308 broiler chickens were divided into 3 groups (n=20). The control group of chickens was fed with complete feed mixtures without any additives. Chickens in the first experimental group were fed a diet containing 1.5% of humic substances. Chickens in the second experimental group were fed a diet containing 1.5% of humic substances and 0.5% of thyme. In 42 day of fattening, 5 male and 5 females with body weight similar to the mean were chosen from each group of chickens. The carcass weight (g), the breast and thigh percentages (%), edible weight (g) and carcass yield (%) were recorded. We found statistical significant increase (P<0.05) of heart weight in the first experimental group in comparison with other groups. The favourable tendency of the effect of the supplements used, although without a statistically significant differences (P>0.05), was observed in both experimental groups in liver and gizzard weights. We recorded statistically non-significant differences (P>0.05) in carcass weight, carcass yield, breast a thigh percentage in the both experimental groups compared with control group.
