| Popis: | The aim of the study was to observe the effect of Cd on the activity of chymotrypsin (ACHT) and trypsin (AT) in droppings of Japanese quails. The birds (24) were divided into four groups of six subjects each. The animals in group 1 received 0.12 mg Cd/d in drinking water, whereas those in group 2 were given 4 mg Zn/d. The quails in group 3 were supplied a combination of 0.12 mg Cd/day and 4 mg Zn/d. The quails in group 4 were not given any supplements, acting as controls. ACHT and AT were determined after 35 and 58d of supplementation. The addition of Cd in drinking water resulted in inhibition of ACHT and AT (p < 0.001) in group G1 in comparison to the control. Zinc showed a positive effect (p < 0.001) on the increase of ACHT and AT in groups 2 and 3. The significantly higher (p < 0.001) ACHT and AT were observed in group G3 with addition of Cd and Zn than in group G1 with addition of Cd. Our results indicated that long‐term supplementation of Zn can have a positive effect on ACHT and AT in droppings of ... |
