Abstract

Trace element additives with Cu (II), Fe (III) and Cr (II) were tested in vitro in a Hen Caecum Model. The levels of Short-Chain Fatty Acid (SCFA) were estimated in. the 4th and 6th h of fermentation. Measurements of hydrogen and methane as fermentation end products were conducted. Any negative influence on the fermentation process were noted. The study observed a higher production of SCFA in the experimental group than in the control group. In the experiment an increase in propionate acid was observed except in the control and Cr (II) groups. It seems to be true that fermentation in experimental groups was more intensive and faster than in the control one. A result of intensive fermentation was a pH decrease in experimental groups but this was the within range value. The lack of a correlation was shown between the level of acetate and methane and hydrogen concentration
