An experiment was conducted to investigate the effects of enzymatically hydrolyzed blood cells (EHBCs) on growth performance, intestinal microflora, intestinal morphology and brush border enzymes in weaned piglets. Seventy-two 28-day-old piglets (6.42±0.06 kg) were randomly allotted to three dietary treatments with six replicates per treatment and four pigs per replicate. They were fed ad libitum one of three iso-nitrogenous experimental diets with fish meal (FM), blood cells (BCs) or EHBCs, respectively. Compared with FM diet and BCs diet, EHBCs diet significantly increased average daily gain (P<0.01) and feed intake (P<0.01), whereas it significantly decreased the fecal score (P<0.05). Moreover, the villous height of the duodenum and jejunum was significantly increased (P<0.05), besides the activity of the aminopeptidase N, maltase and lactase (P<0.05) and the number of lactobacillus (P<0.05) in the cecum. Meanwhile, the number of Escherichia coli was decreased. The results indicated that the EHBCs were beneficial to growth and brush border enzymes and morphology. Thus, EHBCs may be a novel protein source for weaned piglets.
