Abstract: The experiment was done on 180 (2 × 90) Cherry Valley ducks that were fattened until 42 days of age with parity of females and males in the group. The aim of the study was to examine the effect of substituting dehulled lupin seed meal, Zulika variety, for soybean meal and its impact on the fatty acid content of breast and thigh muscle fat. Feeding lupin diets resulted in a significant (P ≤ 0.05) increase in monounsaturated fatty acids (MUFA) in Cherry Valley ducks, as well as significant (P ≤ 0.05) increase in polyunsaturated fatty acids n-3 (PUFA n-3) in breast and thigh muscle fat. There was no effect of the tested diets on PUFA n-6 content in muscle fat. The results confirm that lupin meal in the diet enhances the dietary value of Cherry Valley duck muscle due to the higher proportion of unsaturated fatty acids, with respect to the use of duck meat for human consumption.
