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.

The present study evaluated the effects of dietary N-carbamylglutamate (NCG) on carcass traits, meat quality, and fatty acid profiles in the longissimus dorsi muscle and adipose tissues of Chinese Ningxiang pigs. A total of 36 castrated female pigs with a similar initial weight (43.21 ± 0.57 kg) were randomly assigned to two treatments (with six pens per treatment and three pigs per pen) and fed either a basal diet or a basal diet supplemented with 0.08% NCG for 56 days. Results showed that dietary NCG reduced shear force (p = 0.004) and increased drip loss (p = 0.044) in longissimus dorsi muscle of Ningxiang pigs. Moreover, increased levels of oleic acid (C18:1n9c) (p = 0.009), paullinic acid (C20:1) (p = 0.004), and α-linolenic acid (C18:3n3) (p < 0.001), while significant reduction in the proportions of arachidonic acid (C20:4n6) (p < 0.001) and polyunsaturated fatty acid (PUFA) (p = 0.017) were observed in the longissimus dorsi muscle of pigs fed NCG when compared with those fed the control diet. As for adipose tissues, the C20:1 (p = 0.045) proportion in dorsal subcutaneous adipose (DSA), as well as the stearic acid (C18:0) (p = 0.018) level in perirenal adipose (PA) were decreased when pigs were fed the NCG diet compared with those of the control diet. In contrast, the margaric acid (C17:0) (p = 0.043) proportion in PA were increased. Moreover, the NCG diet produced PA with a greater proportion of total PUFAs (p = 0.001) (particularly linoleic acid (C18:2n6c) (p = 0.001)) compared with those produced by the control diet. These findings suggest that dietary NCG has beneficial effects by decreasing the shear force and improving the healthfulness of fatty acid profiles, providing a novel strategy for enhancing meat quality of pigs.
