Abstract:
Five mature ileorectal anastomosed blue foxes (6.18 +/- 0.15 kg) were used in digestibility experiments to evaluate the L-carnitine apparent ileal absorption from diets used in reproductive polar fox nutrition over the year-long farm-feeding period on two domestic farms (A and B) differing in reproduction results. The concentration of L-carnitine was higher in diets from farm B (136.1-241.7 mg kg (-1) DM) than in the diets frorn farm A (88.5-135.2 ing kg(-1) DM). The coefficients of ileal apparent absorption of L-carnitine ranged from 60.23 to 75.57% for diets A (farm A) composed mainly of fish and poultry offals. The coefficients of ileal apparent digestibility of L-carnitine were higher for diets B (farm B) (83.75-94.78%; P < 0.05) based on beef offals. These data indicate high concentration and efficient ileal apparent absorption of L-carnitine from diets used in reproductive polar fox nutrition on both farms examined.
