Summary, Etc. Note: |
Abstract: Mallard ducks (Anas platyrhynchos) were given either 0, 2, or 4 No. 6 lead shot in combination with 4 grit treatments; no grit, coarse sand, mica granite, and crushed oyster shell. Each combination was replication three times. Ducks were maintained on a diet of whole corn. An analysis of variance indicated no significant differences in mortality in relation to grit type, but a significant difference (at 0.05 level) in mortality between the lead shot doses. Oyster shell grit apparently reduced mortality of ducks dosed with 4 shot but not to a degree statistically significant. In all treatments, mortality was closely associated with shot retention. Ducks retaining shot for 2 weeks usually died. |
