Popis:	The effect of the level of dietary non-fiber carbohydrates (NFC) on intake, in vivo digestibility, milk production and endocrine-metabolic status was studied in 20 Sarda ewes (mean ± SE, BW 42.5 ± 3.9 kg) at mid-lactation stage (89 ± 1 DIM). Ewes were divided into 2 groups and fed chopped alfalfa hay at 400 g/d and pelleted concentrates ad libitum in metabolic cages during 3 weeks. The concentrates differed in NFC concentration (NFC = 36% of DM: group NFC36; NFC = 23% of DM: group NFC23), due to the substitution of cereal grains with soybean hulls in the low NFC diet. Dry matter intake was higher for NFC23 than for NFC36 (2900 g/d vs. 2555 g/d; P vs. 62.9%, P vs. 56.1%, P P > 0.2). Dietary NFC concentration negatively affected milk yield (1813 ml/d vs. 2110 ml/d, for NFC36 and NFC23 groups, respectively, P vs. 4.51%, P vs. 5.19%, P > 0.2). Body fat increased ( P P P P
