Dietary Flaxseed Meal and Chromium: a Nutritional Intervention in Broiler Chicken to Study the Prospective Growth Performance, Tissue Lipid Composition and Metabolism, Health Indices, and Serum Lipid Chemistry

Abstract Background:Flaxseed in a richest terrestrial source of w-3 fatty acid – alpha-linolenic acid (ALA) which can be incorporated in chicken meat when it is included in chicken ration. ALA can further be acted up on by desaturating enzymes to generate PUFA such as EPA and DHA which increase the health value of chicken meat. However, dietary flaxseed results in concurrent increase in lipid oxidation due higher unsaturation and negative impact on chicken growth performance. These negative effects of flaxseed feeding can be reversed by chromium supplementation in broiler chicken. Thus, this study investigated growth performance and efficiency, lipid composition, lipid metabolism, health indices, and serum lipid chemistry of broiler chicken fed flaxseed meal (FSM) and chromium (Cr).Results:Feeding of 100 g FSM exerted negative effects on the growth performance during starter phase only (0-3 weeks) and overall growth efficiency parameters in broiler chicken, whereas, Cr supplementation reversed these negative effects.100 g FSM reduced abdominal fat in chicken and Cr supplementation linearly decreased it with minimum at 1.5 mg Cr/kg diet.Feeding of 100 g FSM favourably improved the activities of lipid metabolism enzymes which resulted in improved fatty acid profile and health indices of chicken meat.No significant effect of Cr supplementation was observed on lipid metabolism, fatty acid profile, and health indices of chicken meat.100 g FSM decreased serum total cholesterol, triglyceride, cardiac risk ratio, atherogenic coefficient, and atherogenic index of plasma, whereas, Cr supplementation decreased these parameters linearly with increasing levels. Antioxidant enzyme activities and lipid peroxidation were increased by FSM, whereas, Cr supplementation linearly decreased them with increasing levels; and inverse trend was observed in serum HDL cholesterol levels.Conclusions: Feeding of 100 g FSM exert negative effects on growth performance of young chicken (0-3 weeks), favourably alter lipid metabolism which results in improved fatty acid profile and health indices of chicken meat. It improves the serum lipid profile and atherogenic indices in broiler chicken, but negatively affects the oxidative stability of lipids. However, Cr supplementation at the rate of 1.5 mg/kg diet successfully overcomes these negative effects of FSM feeding on growth performance and lipid oxidative stability.

Flaxseed Meal

AbstractThe present study aimed to evaluate growth performance and meat quality of broiler chicken with respect to feeding of 100 g flaxseed meal (FM)/kg and increasing lysine levels in the broiler diet. The results revealed no effect of lysine and FM feeding on growth performance except for a negative effect of FM on feed efficiency of birds, which was countered by feeding 1.25 BIS lysine. Feeding FM improved the fatty acid profile of broiler chicken meat significantly, whereas no effect was observed for increasing lysine levels beyond BIS recommendation. FM significantly reduced meat cholesterol, fat, water-holding capacity (WHC), extract release volume (ERV) and antioxidant potential, whereas it increased the pH of fresh meat, drip loss and lipid peroxidation of broiler chicken meat. As compared with other lysine levels, generally 1.25 BIS lysine significantly increased the pH of refrigerated stored meat, WHC, ERV and antioxidant potential, whereas it significantly reduced cholesterol, fat, drip loss and lipid peroxidation of broiler chicken meat. Thus, the inclusion of 100 g FM/kg diet along with 1.25 BIS lysine in broiler ration was optimum for desirable broiler performance, fatty acid profile, oxidative stability and other functional properties of broiler chicken meat.

AbstractThis study investigated the role of dietary prebiotic mannan-oligosaccharides (MOS), and probiotic Bifidobacterium bifidum (BFD) in lipid metabolism, deposition, and consequent health indices in broiler chicken. The supplementation of 0.2% MOS along with either 106 or 107 CFU BFD/g feed resulted in downregulation of Acetyl-CoA carboxylase, fatty acid synthase, sterolregulatory element binding protein-1, and apolipoprotein B100; and up-regulation of peroxisome proliferator activated receptor-α AMP-activated protein kinase α-1, and stearoyl CoA (∆9) desaturase-1 hepatic expression in broiler chicken. The birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed depicted lower body fat percentage, palmitic acid, stearic acid, and saturated fatty acid contents, whereas, higher palmitoleic acid, oleic acid, and MUFA contents were observed. The ∆9-desaturase indices of chicken meat have shown higher values; and elongase index (only thigh) and thioesterase index have shown lower values in birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed. The meat health indices such as Polyunsaturated fatty acids (PUFA)/Saturated fatty acids (SFA) ratio, Mono-saturated fatty acids (MUFA)/SFA ratio, unsaturated fatty acids (UFA)/SFA ratio, hypocholesterolemic/hypercholesterolemic fatty acid ratio, saturation index, atherogenic index, thrombogenic index, and hypercholesterolemic fatty acid content were positively improved in birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed. Similarly, the birds supplemented with 0.2% MOS along with either 106 or 107 CFU BFD/g feed have shown lower serum triglyceride and total cholesterol levels along with higher high density levels and improved serum health indices cardiac risk ratio, atherogenic coefficient, and, atherogenic index of plasma.
