“…Furthermore, the results indicated that the dams were able to maintain nutrient homeostasis when the protein: carbohydrate ratio of the feed ranged widely. During the lactation period, Glem-Hansen (1979) found that 43% to 53% of ME derived from protein ensured a normal kit growth performance. According to common Scandinavian practice, the diet during the lactation period is recommended to contain a minimum of 40% of ME from protein, 40 Á/50% of ME from fat and a maximum of 20% of ME from carbohydrates to support normal growth performance and health of dams and kits (Hansen et al, 1991).…”
