The immunologic effects of lead were measured in game-farm mallards (Anas platyrhynchos) that ingested lead shot while foraging naturally, mallards intubated with lead shot, and unexposed controls.

Birds fed whole mixed grain had increased mortality and a higher prevalence of lesions than did ducks fed a commercial ration. The retention of pellets in the gizzard of week-old mallards was greater than was shot retention in 5-week-old birds, but no difference was observed in the dissolution rate of shot between the two age by: 2.

Abstract. Captive game-farm mallards (Anas platyrhynchos) were dosed with five No. 4 lead (Pb) shot and placed on a diet of shelled corn or commercial duck food (6 ducks).Half of the ducks on each diet was dosed daily with 10 g of soil.

The commercial duck food provided more protection from the effects of Pb toxicity than the 10 g of soil dosed by: 5. to study possible interaction between ingested lead, lead-iron and iron shot and P.

(A) bird on the left is passing 1 pellet through the intestine. Mallard ducks (Anas platyrhynchos) were sacrificed one month after ingesting one number 4 all-lead shot or one number 4 lead-iron shot. Livers, kidneys, blood, wingbones, and eggs were analyzed for lead by atomic absorption.

Necropsy of sacrificed ducks failed to reveal any of the tissue lesions usually associated with lead poisoning in waterfowl.

The object was identified as lead shot pellet used for game hunting, and marks on it showed that it had been fired through a rifle.

The lead shot pellet had a diameter of 6 mm and a mass of g (Figure 2). A new abdominal X ray confirmed that the object was no longer in the by:   Large lead shot, #4 or larger, is not ingested by ducks.

Toxicity of Lead Shot among Pen-Reared Mallards, Black Ducks, and Wild Mallards In all tests comparing the relative toxicities of proposed substitute materials with that of commercial lead shot, we used pen- reared mallards, a standard dose of eight, size 6, shot (1 g).

By Bevan McNaughton. Introduction: This report was produced to bring attention to hunters and conservationists alike to the issue of the effect that spent lead shot pellets may have on waterfowl and its long lasting presence in the environment.

Both acute and chronic effects occur in response to lead exposure including death. Most research has focused on the availability and ingestion of spent lead shot by waterfowl, especially prior to the federal ban on use of toxic shot for waterfowl hunting.
