Abstract
Summary A 105-day experiment was conducted with 600 BIG 6 female turkeys to determine the effect of Progres (natural resin acids [RA] of Scots pine and Norway spruce) on the growth performance of birds, the incidence of footpad dermatitis (FPD), litter quality, carcass quality, and the structure and function of the gastrointestinal tract (GIT) (pH, viscosity, short-chain fatty acids) (3 treatments, 10 replicates, and 20 birds per replicate). The birds received a basal diet without RA (T1), or diets supplemented with RA at 0.5 kg/t (starters 1 and 2, finisher) and 1.0 kg/t (growers 1 and 2) (T2), or diets supplemented with RA at 0.75 kg/t (starters 1 and 2, finisher) and 1.5 kg/t (growers 1 and 2) (T3). The inclusion of the Progres RA preparation in turkey diets increased the BW of birds by 1.6% (0.5–1.0 kg/t RA) and 2.1% (0.75–1.5 kg/t RA—P ≤ 0.05. Dietary supplementation with RA significantly improved the values of the feed conversion ratio (P
