Effects of Dietary Supplementation with Ferulic Acid or Vitamin E Individually or in Combination on Meat Quality and Antioxidant Capacity of Finishing Pigs

چکیده
This study aimed to evaluate the effects of vitamin E (VE), ferulic acid (FA) and their combination supplementation on meat quality and antioxidant capacities of finishing pigs. Sixty barrows were randomly allocated to four experimental diets using a 2×2 factorial arrangement with 2 VE supplemental levels (0 or 400 mg/kg) and 2 FA supplemental levels (0 or 100 mg/kg) in basal diets. After 28 days, six pigs per treatment were slaughtered. The results showed that VE supplementation increased loin eye area of pigs (p<0.05) and FA supplementation increased pH45min value (p<0.05). The interaction of FA×VE was observed in shear force of longissimus dorsi muscle (p<0.05). Moreover, supplementation with VE decreased hepatic and sarcous malondialdehyde (MDA) content, increased hepatic glutathione (GSH) content and sarcous glutathione peroxidase (GSH-Px) activity (p<0.05). Additionally, supplementation with FA increased hepatic GSH-Px activity and decreased sarcous MDA content (p<0.05). However, dietary treatment did not affect the expression of genes related to nuclear factor, erythroid 2-like 2 (NFE2L2) pathway. These results suggest that dietary FA and VE could partially improve meat quality and antioxidant capacity of finishing pigs, but not by activating NFE2L2 pathway under the normal conditions of farming.

In total thirty pigs (Slovak Meaty) defined by DNA based test as not susceptible to malignant hyperthermia (non-mutant on RYR1) were used in the experiment. Treatment consisted in supplementation of vitamin E (500 mg α-tocopherol/kg diet as α-tocopherol acetate) (group E) and the same doses of vitamin E plus vitamin C (200 mg L-ascorbic acid/kg diet) (group E + C) to finishing pigs for the last...

The effects of dietary supplemental guanidinoacetic acid (GAA) on performance, biochemical indices and meat pH of broilers with cold-induced ascites were studied. A total of 640 day-old male broiler chicks (Cobb 500) were assigned to four dietary treatments including control diet; control diet supplemented with either 0.6, 1.2 or 1.8 g of GAA per kg of feed. Each treatment was replicated in 8 b...
