Bombik E, Bombik A, Pietrzkiewicz K. Analysis of Zinc and Copper Content in Selected Tissues and Organs of Wild Mallard Ducks ( Anas platyrhynchos L.) in Poland. Animals (Basel) 2024; 14:1176. [PMID: 38672324 PMCID: PMC11047566 DOI: 10.3390/ani14081176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 03/25/2024] [Accepted: 04/11/2024] [Indexed: 04/28/2024] Open
Abstract
The research material included selected muscles and liver of mallard ducks obtained in two research areas. A total of 28 mallards were obtained for the study-six males and six females from the Siedlce hunting district and eight males and eight females from the Leszno hunting district. Zinc and copper concentrations were determined by inductively coupled plasma optical emission spectrometry (ICP OES). It was concluded from the study that the Leszno hunting district is more polluted than the Siedlce hunting district. Among the examined tissues of mallard ducks from both hunting districts, the highest content of zinc and copper was found in the liver. In this organ, birds shot in the Leszno hunting district were characterized by a significantly higher content of these elements compared to birds shot in the Siedlce hunting area. The significantly higher average zinc and copper concentrations in the liver of mallards harvested in this hunting district may have been influenced by fertilization of crop fields in this area with fertilizers containing these elements and by extraction of ore containing zinc and copper minerals in the Legnica-Głogów Copper District. This is an important problem with regard to the safety of consumers of game meat. It was shown that the tissues of male mallards were characterized by higher average levels of zinc and copper than those of females, but the differences were statistically significant only in the case of the average copper content in the leg muscles.

Abstract
Duck meat is known for its taste and high nutritive value. To preserve local genetic diversity while maintaining commercial viability, we obtained a crossbreed (CB) between high-performing Cherry Valley (CV) and traditional Chinese crested (CC) ducks. We compared carcass traits and meat quality characteristics of CB and parental breeds. Meat from the above ducks at their respective marketable ages was evaluated for proximate composition, amino acid and fatty acid profiles, and selected mineral content. The live weights, carcass weights, and breast muscle percentage of CB were higher than CC but lower than CV; the leg muscle of CB was lower than CV and CC. CB had higher intramuscular fat content than CV; its collagen content was lower than CC but higher than CV in breast and thigh muscles. Additionally, the saturated fatty acid content of CB muscle was lower than CV and higher than CC. CB contained more monounsaturated fatty acids than CV and CC. Zn content was higher in CB breast than CV and CC. CB, obtained by crossing CV and CC, has partial advantages over both the breeds suggesting that these characteristics aligned with standards to breed ducks with high-quality meat.
