- Abstract
The experiment was to investigate the effect of iron-rich Candida utilis on growth performance, blood indexes and intestinal morphology of weaned piglets. A total of 90 healthy 28-day-old 'Duroc × Landmass × Yorkshire' weaned piglets with an average body weight of (7.86±0.54) kg were randomly divided into two groups, with nine replicates in each group and five piglets in each replicate. Piglets in CON group were fed with a basal diet + ferrous sulfate (containing 104 mg/kg iron), and piglets in experimental group (CU group) were fed with a basal diet + iron-rich Candida utilis (containing 104 mg/kg iron). The experiment lasted for 28 d. The results showed that there was no significant effect of iron-rich Candida utilis on growth performance of weaned piglets (P>0.05). Compared with CON group, the total number of WBC and Bas in CU group were significantly increased (P<0.05). The content of serum IgA and IgG were significantly increased (P<0.05), and TNF-α was significantly decreased (P<0.05). The serum iron content was significantly increased, while the total iron binding capacity and ceruloplasmin activity were significantly decreased (P<0.05). Compared with CON group, the activity of serum catalase, cytochrome oxidase, glutathione peroxidase and total superoxide dismutase in CU group were significantly increased (P<0.05), and the content of serum malondialdehyde was significantly decreased (P<0.05). The villus height and villus height/crypt depth values in duodenum and jejunum of weaned piglets in CU group were significantly increased (P<0.05), and crypt depth was significantly decreased (P<0.05). The study indicates that the complete replacement of dietary inorganic iron by iron-rich Candida utilis can improve the iron metabolism, antioxidant and immune functions of weaned piglets, which is beneficial to the maintenance of intestinal morphology.
