The Effect of Adding of the Enzyme Products Xybeten and Protozin-A to a Diet on Ethological Parameters of Sheep

It has been studied the effect of adding synthetic multienzyms Xybeten and Protozin-A in the ration by examining basic behavioral activities of sheep. The experiment has been carried out using the period's method. During the test period the enzyme products are added at dose 1 g/kg mixture concentrate. Animal behavior is studied through direct individual continuous monitoring for 24 hours. The basic functional activities registered in the ethograms are: feeding, moving and rest as well as markers for presence of discomfort. It was found that the addition of Protozin-A and Xybeten to ration is not perceived as a stressor and is suitable for use as promoters of the digestive processes in sheep. Protozin-A has more significant effect on feeding activity as stimulator. Xybeten increases the number of chewing movements (P<0.01) and duration of rumination (P<0.01) per 1 bolus. The sheep spend most time on the feeding activity, followed by time spent on rest when environmental conditions are controlled by human.
