- Abstract
The study was conducted to assess the effects of medicinal plants powder (MP) (60% Bindens pilosa L., 30% Urena lobata L. and 10% Ramulus cinnamomi) as a feed additive to promote growth performance and improve meat quality in pigs. Seventy-two crossbred pigs [Duroc × (Landrace × Yorkshire)], initial body weight 30.3 ± 1.66 kg, were randomly divided into 4 dietary groups, 3 replicates of 6 pigs each. Each group was randomly allocated to one of four dietary treatments: a basal diet (control diet, T0) and three experimental diets (T20, T40 and T60) based on T0 diet supplemented with MP at 20, 40 and 60 g/kg of feed. The experiment lasted for 14 weeks, including 2 periods of feeding programmes (weeks 0-7 and 7-14). A reduced average daily feed intake (linear, P = 0.01) and a decreased trend in average daily gain (ADG) (linear, P = 0.08) were observed in pigs fed diets with 40 and 60 g/kg MP in comparison to the control diet in weeks 0-7. There was no statistical difference in ADG and feed conversion ratio between treatments over the entire trial period. Dietary MP supplementation decreased backfat thickness (quadratic, P = 0.04) and cholesterol content (linear, P = 0.02; quadratic, P = 0.01) in meat. The sensory quality of cooked meat was improved (P < 0.0001) by the inclusion of MP. So, dietary MP supplementation could have the potential to improve sensory quality and decrease backfat thickness and cholesterol content in meat without a negative effect on growth rate of pigs and technological quality of pork.
