Available in PDF, EPUB and Kindle. Book excerpt: Wing bones of 4,190 ducks of seven species collected in 1972 and 1973 were analyzed for lead to provide a base line for lead burdens and to determine geographic patterns of lead exposure in these species. Lead residues ranged from trace amounts to 361 ppm and reflected the history of exposure to lead from ingested shotshell pellets and other sources. Wing bones of adults contained higher residues than did those of immatures. Levels were lower in birds from the Central Flyway than in those from other flyways.

This book was released on 1974 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poisoning of North American waterfowl resulting from the ingestion of lead shot by ducks, geese, and swans causes an estimated annual mortality of 2% to 3% of the population. To alleviate this problem the search for a suitable substitute for lead has been underway since the early 1950's. Proposed substitutes for lead shot were evaluated in a series of acut toxicity tests with pen-reared mallards. Most candidate materials were as toxic to ducks as commercial lead shot. Coating or alloying lead with other materials only delayed mortality among dosed ducks.

Download or read book Test of Grit Types in Alleviating Lead Poisoning in Mallards written by Alfred J. Godin and published by . This book was released on 1967 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 oystershell. 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. Oystershell grit apparently reduced mortality of ducks dosed with 4 shot but not to a degree statisticallty significant. In all treatments, mortality was closely associated with shot retentiion. Ducks retaining shot for 2 weeks usually died.
