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.

It is recognised that n-3 polyunsaturated fatty acids (PUFA) are important components of a healthy human diet. There is, therefore, considerable interest in manipulating animal tissue fatty acid composition to enhance n-3 PUFA intakes. Linseed is a rich source of the n-3 fatty acid, linolenic acid (C18:3n-3). When whole linseed (WL) is included in poultry diets this fatty acid can be incorporated into tissue lipids and may also serve as a precursor for the synthesis of longer chain C20 and C22 n-3 PUFA in chicken tissues. To counteract the increased susceptibility of PUFA-enriched tissues to peroxidation, α-tocopherol acetate (ATA) supplementation of the diet may be required. In this study the effect of WL and supplementary ATA on broiler growth performance and leg and breast muscle fatty acid profiles and lipid peroxidation were studied

He, M. L., Gibb, D., McKinnon, J. J. and McAllister, T. A. 2013. Effect of high dietary levels of canola meal on growth performance, carcass quality and meat fatty acid profiles of feedlot cattle. Can. J. Anim. Sci. 93: 269–280. This study investigated the effect of substituting canola meal (CM) for barley grain on growth performance, carcass quality and meat fatty acid (FA) profiles of feedlot cattle. Cross bred calves (n=140; 285±27 kg) were individually fed diets comprised of a barley grain based concentrate (including 5% supplement) and barley silage at ratios of 45:55 and 92:8 (DM basis) during growing and finishing periods, respectively. Pressed CM from Brassica napus, containing 11.4% residual oil and solvent-extracted CM derived from B. napus or Brassica juncea canola seed were compared. Canola meal was substituted for 0 (control), 15, or 30% barley grain (DM basis) in both growing and finishing diets. Regardless of diet, cattle did not differ (P>0.05) in average daily gain in either the growing or finishing period. For the overall feeding period, inclusion of 30% CM increased (P<0.01) DMI of cattle compared with 15% CM groups, but reduced (P<0.05) gain: feed (G:F) as compared with control and 15% B. juncea and 15% pressed CM. Gain: feed of cattle fed CM was also reduced (P<0.05) during the finishing period as compared with the control diet with this reduction being more notable at the 30% level. Carcass quality and incidence of liver abscesses were not affected (P>0.05) by inclusion of CM. Inclusion of 30% pressed CM resulted in higher (P<0.05)%FAME of total polyunsaturated fatty acid, n-3, alpha-linolenic acid and conjugated linoleic acid (CLA), and a decrease (P<0.05) in n-6/n-3 ratio in the pars costalis diaphragmatis muscle as compared with the control diet. In conclusion, inclusion of CM did not alter the growth performance or G:F of beef cattle during the growing period, but did lower G:F during the finishing period. The inclusion of 15 or 30% solvent-extracted CM did not alter carcass quality, whereas 30% pressed CM increased the levels of desirable fatty acids (i.e., n-3 and CLA) in beef.
