Efficiency of feeding Arctic foxes of different sizes


, : Efficiency of feeding Arctic foxes of different sizes. Krolikovodstvo i Zverovodstvo ( 5): 10

Offspring of large or small pairs of Arctic foxes were separated into groups according to liveweight, sex, age and size. They were fed on diets containing digestible protein 7.5, 8.5 or 9.5 g/100 kcal metabolizable energy (ME), without or with ionol (an antioxidant) and an enzyme preparation, Aminosubtilin, at 20 and 50-80 mg/100 kcal ME, respectively. In autumn some foxes in the group given protein 9.5/100 kcal ME received 50% additional dry feeds.
