Abstract

Chinese Taihe Black-bone silky fowl (TBsf) is the homology of medicine and food and has high nutritional and medical value all over the world. However, the nutritional compositions and specific metabolite advantages of Taihe silky fowl muscle are still poorly understood. In this study, we investigated the differences of nutritional components between TBsf and another similar breed (Black Feathered chicken and laid green-shelled eggs, BF-gsc). Meanwhile, we also explored the divergences in muscle characteristics of Taihe silky fowl fed with two different diets, that is normal chicken feed (TBsf-ncf) and Broussonetia papyrifera-fermented feed (TBsf-bpf). Firstly, the growth performance and biochemical index of Taihe silky fowl was significantly different compared with black-feathered chicken. Secondly, we identified the metabolic alterations in Taihe silky fowl by performing an un-targeted UHPLC-Q-TOF-MS/MS analysis. Our results suggested that the whole metabonomic characteristics had obvious separation between TBsf-ncf, TBsf-bpf and BF-gsc groups both in the positive and negative ion mode by PCA analysis. Next, OPLS-DA multivariate analysis revealed that 57 metabolites (in positive mode) and 49 metabolites (in negative mode) were identified as differential metabolites between TBsf-ncf and BF-gsc group. These differential metabolites were mainly enriched to ABC transporters, biosynthesis of amino acids and aminoacyl-tRNA biosynthesis. Besides, there were 47 metabolites (in positive) and 13 metabolites (in negative) were differentially regulated between TBsf-ncf and TBsf-bpf group, which were majorly involved in histidine metabolism and linoleic metabolism. Furthermore, the integrated network analysis suggested that DL-arginine, DL-isoleucine, linoleoylcarnitine, stearoylcarnitine (positive) and ricionleic acid, D-proline, uric acid (negative) were the significantly metabolic biomarkers in Taihe silky fowl. Moreover, the metabolites of primaquine, ticlpoidine, riboflavin, acetylcarnitine (positive) and salicylic acid, acetaminophen sulfate, glutamic acid (negative) were markedly changed in the Taihe silky fowl fed with BP-fermented feed. In summary, a global survey of the nutritional components and metabolite differences were performed in muscle tissues of Taihe silky fowl between various breeds and feeds. The comprehensive expression profiles of the metabolites in Taihe silky fowl affected by genetic and environmental factors were acquired. This study provided valuable evidence fo breed and feed-induced putative biomarkers as well as improved the economic value of Taihe silky fowl through targeted metabolite regulation.
