The aim of the study is to determine the effect of the multienzymatic preparations Hostazym C 100 and Hostazym X 100 on the total quantity and molar percentage of volatile fatty acids in rumen content of lambs fed ad libitum with meadow hay and concentrated mixture. The experiment was conducted with 18 male lambs. Karakachan breed. at the age of two months with average live weight of 15.81±1.5 kg at the beginning of the trial. The animals are raised in three groups – control and two experimental. The three groups received the same ration in stock. 10 days before the beginning of the experiment to the concentrate mixture for the first experimental group was added the multienzymatic preparation Hostazym C 100 at the dose of 1g/kg concentrate. and to the second trial groups ration – Hostazym X 100 in the same dose and route of administration. Hostazym C 100 is a commercial product with leading endo-1.4-β-glucanase and secondary cellulase. α-amylase. protease and hemicellulase. Hostazym X 100 is with main endo-1.4-β-xylanase activity and secondary cellulase. α-amylase. protease and hemicellulase. It was found that adding of Hostazym C 100 in the ration of lambs. fed with meadow hay and concentrated mixture ad libitum. lead to increase the total quantity of volatile fatty acids - P0.05. Enzymatic preparation Hostazym X 100 decreased relative quantity of isobutyric and butyric acid - P0.05. There is no statistically significant differences in molar percentage of acetic and propionic acid after adding of Hostazym C 100 or Hostazym X 100 in the concentrated feed of the experimental animals. but it is outlined a tendency of increasing percentage of both acids.
