ABSTRACT

Objectives: To investigate the effects of dietary turmeric on growth performance, nutrient digestibility, hematological and biochemical values, and intestinal histology in nursery pigs. Materials and methods: A total of 48 nursery pigs were divided into groups receiving 0.00%, 0.05%, 0.10%, and 0.20% turmeric in the feed, with four replicates. Experiment 1: visceral organs and light microscopic parameters (eg, intestinal villus height) were measured at 30 kg body weight (BW). Epithelial cell morphology on the villus apical surface was observed using a scanning electron microscope. Experiment 2: blood was collected at 40 and 80 kg BW for hematology, triglyceride, and cholesterol assays. Growth performance was compared at 90 kg BW. Results: Growth performance and carcass and visceral organ weights did not differ between turmeric and control groups. Nutrient digestibility was higher in the 0.10% group (P < .05). Duodenal weight was lower in all treated groups than in the controls, and ileal weight was lower in the 0.10% and 0.20% groups (P < .05). At 80 kg BW, hematocrit was lower in the 0.10% group (P < .05). White blood cell counts were higher in the 0.10% and 0.20% groups, and triglycerides and cholesterol in all treated groups (P < .05). Cell mitosis numbers were higher in the jejunum and ileum of the 0.10% and 0.20% groups (P < .05). Protuberant mucosal epithelial cells and cell clusters were observed in treated groups. Implications: Under the conditions of this study, dietary turmeric promotes nutrient digestibility, enhances hematological values, and induces intestinal epithelial cell hypertrophy.
