Content and apparent ileal digestibility of protein and amino acids in diets fed to parent stock of farm-raised polar foxes (Alopex lagopus L.)
This study aimed to compare content and apparent ileal digestibility of protein and amino acids in diets used over 1 year (4 feeding periods) on 2 farms of reproductive polar foxes (A and B). Two diets (1 from farm A, 1 from farm B) from the same feeding period were tested in succession (4 eight-day...
