The Interaction Between Dietary Fat Level, n-3 LC-PUFA, and Zinc on Their Postprandial Absorption Kinetics in Atlantic Salmon (Salmo salar).

ABSTRACT: Two short-term feeding trials were conducted on Salmo salar, with the interaction between dietary zinc (Zn) and fat level in trial 1 and with the interaction between dietary Zn and n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) in trial 2, focusing on postprandial plasma parameters, intestinal Zn and fat uptake and transport. After 4-week feeding interventions, samples were collected at different postprandial time points, ranging from 0 to 36/38 h after feeding. Results showed that increased Zn level in feed significantly increased the postprandial plasma Zn level in trial 1 (8-9°C). On the contrary, the postprandial plasma Zn level was not affected by the dietary Zn under higher temperature conditions (trial 2, 10-12°C). Further, analyzed markers related to intestinal Zn
