Abstract Background: There are abundant anthocyanin compounds in purple corn, which has a wide range of biological activity in terms of antioxidation, scavenging free radicals, and preventing lipid peroxidation. However, the impact of anthocyanins on the meat quality, muscle antioxidant activity and fatty acid profiles in growing goats has not been studied. This experiment was conducted to observe the effects of anthocyanin from purple corn pigment (PCP) on growth performance, nutrient digestibility, meat quality, muscle antioxidant activity and fatty acid profiles of goats during the growing period. It aimed to provide the important rationale for anthocyanin preventing lipid peroxidation in goats.Results: A total of eighteen Qianbei Ma wether kids (body weight, 21.38 ± 1.61 kg; mean ± standard deviation) were randomly allotted into three groups using a completely randomized design with six duplicates per group. The dietary treatments were: 1) the control group was provided with basal diet; 2) treatment 1 (LA) was provided basal diet with 0.5 g/d PCP; and 3) treatment 2 (HA) was provided basal diet with 1 g/d PCP. The results showed that supplementation of PCP anthocyanin could increase (P < 0.05) CP and GE digestibilities compared to the control. The addition of PCP tended to drop (P < 0.05) shear force during the growing goat phase. Goat receiving PCP showed higher (P < 0.05) levels of reduced glutathione, DPPH scavenging activity, and peroxidase in Longissimus dorsi muscle (LD) relative to the control. Compared with the control, LA and HA displayed lower (P < 0.05) concentrations C10:0, C12:0, C14:0, C15:0, C16:0, C17:0 and saturated fatty acid (SFA), but increased (P < 0.05) various individual unsaturated FA of C14:1, C16:1, C17:1, C18:1n9, C18:1n12, C18:2n6, C18:3n3, C20:4n6, C22:1n9, C22:4, C22:5n6, C22:6n3, C24:1, PUFA, n-6 PUFA, MUFA/SFA and PUFA/SFA. Specifically, some stronger (P < 0.05) positive correlations were detected between antioxidant status and UFA profiles (GSH-Px, GSH, catalase, DPPH scavenging activity with C14:1, C15:1, C16:1, C18:1n9, C20:4n6, C22:1n9, C22:4, C22:5n6, C24:1, MUFA) in LD of goats.Conclusion: Results indicated that anthocyanin could be used as a source of natural functional additive because anthocyanin-rich PCP had the potential to improve growth performance, meat quality, and enhance muscle antioxidant status and unsaturated FA profiles in the growing goats.

This study was performed to evaluate the effects of dietary chitosan supplementation on growth performance, lipid metabolism, gut microbial, antioxidant status and immune responses of juvenile loach (Misgurnus anguillicaudatus). Five experimental diets were formulated to contain graded levels of chitosan (0 (control), 0.5, 1, 2 and 5% CHI) for 50 days. Results of the present study showed that body weight gain was significantly higher in fish fed chitosan supplemented diets in dose dependent manner than control group. Increasing dietary chitosan levels reduced gut lipid content. Meanwhile the mRNA expression levels of intestine lipoprotein lipase and fatty acid binding protein 2 were significantly reduced with incremental dietary chitosan level. The percentages of total monounsaturated fatty acid decreased, while polyunsaturated fatty acid increased with dietary chitosan. The fish fed 0.5% CHI had higher mucus lysozyme activity (LZM) than those fed 0% CHI, but the LZM activity was significantly decreased with advancing chitosan supplement. The expression levels of superoxide dismutase, catalase and glutathione peroxidase revealed a similar trend, where the highest expressions were found in fish fed 5% CHI diet. In the term of intestine microbiota between 0 and 1% CHI groups, the proportion of bacteria in the phylum Bacteroidetes increased, whereas the proportion of bacteria in the phylum Firmicutes decreased as the fish supplemented chitosan. In conclusion, supplementation of chitosan improved growth performance, antioxidant status and immunological responses in loach.
