Abstract

【Objective】 To investigate the effects of substituting fermented non-conventional feed for the basal diet in fattening Bamei pigs. 【Methods】Seventy-two Bamei pigs during the fatling period were randomly divided into two groups, each containing six replicates with six pigs per replicate. The control group (CK) was fed a corn-soybean meal basal diet, while the experimental group (FK) received the basal diet supplemented with 10% fermented non-conventional feed (dry matter basis) as an equal replacement. After 60 days of feeding, twelve pigs from each group were slaughtered for sample collection and performance evaluation. 【Results】 The results demonstrated that fermented non-conventional feed significantly reduced the cardiac organ index (P < 0.05) and increased the renal organ index (P < 0.05). Regarding immune-related gene expression, the feed markedly elevated the relative mRNA expression levels of IL-1, IL-2, TNF, IgA, and IgM in both lymphoid and hepatic tissues (P < 0.01). 【Conclusion】 In summary, replacing 10% of the basal diet with non-conventional fermented feed improves the health status and immune function of fattening Bamei pigs. Thus, substituting conventional feed with fermented non-conventional feed is not only feasible but also offers an economically efficient nutritional strategy for local pig breeds farming.
