Abstract
The effect of alga biomass (Chlorella vulgaris) on somatic growth, mortality rate and development of some indicators of defense was investigated in the first month after incubation in trials on 1,069 pheasants kept in the nursing facility of feathered game. The experimental group (n=568) received 2.5 % Ch. vulgaris in the feed mixture BZ I in the first week and 0.5 % in the second week of life. Phagocytic activity of leucocytes was also determined, and at the end of the first month of life the pheasants were subject to cold stress tests, when body temperature, O2 consumption and CO2 output were measured. In comparison with the control, the addition of Ch. vulgaris increased the live weight of the experimental pheasants by 6.8 % at the end of the second week and by 8.4 % at the end of the first month of life (p0.01). The mortality rate over fist month amounted to 46 birds in control, i.e. to 9.2 %, and to 24 birds in the experimental individuals, i.e. to 4.2 %. The experimental pheasants kept under laboratory conditions showed an earlier increase in the counts of monocytes (0.02p0.05) and the phagocytic activity at the end of the first month of life also had significantly higher values in these birds (0.02p0.05). A strong cold stress induced approximately the same decrease in body temperature, O2 consumption in both groups, but the experimental individuals significantly exceeded the values in the control (p0.01).
