Concentrazione plasmatica degli ormoni tiroidei, caratteristiche della fibra e attività dei follicoli piliferi in capretti angora: effetti della supplementazione con favino (Vicia faba minor)

SUMMARY - Angora goats from parturition and their kids after weaning, fed mixed hay ad libitum and grazing pasture, were supplemented (T) or not (C) with horse bean. T3 and T4 plasma concentrations resulted higher in T kids in comparison with C (9.36±2.05 vs 3.76±2.37 ng/mL for T3 and 14.55±1.83 vs 9.44±1.37 g/dl at 155 d age), and affected by treatment (P<0.05). The supplementation increased fibre length (T 5.82±0.13 cm, C 5.16±0.14 cm, P<0.001) and the ratio active: total secondary follicles (T 0.96±0.01, C 0.91±0.02, P<0.05), and decreased secondary fibre diameters (T 16.54±0.35 m, C 18.09±0.31 m, P<0.01).
