Abstract:


Background: Deoxynivalenol contamination is increasing worldwide, presenting great challenges to food security and causing great economic losses in the livestock industry.

Objective: This study was conducted to determine the protective effect of baicalin zinc as a dietary supplement on pigs fed with a deoxynivalenol-contaminated diet.

Method: A total of 40 weaned pigs (21 d of age; 6.13 ± 0.42 kg average BW) were randomly assigned (10 pigs/group) to 4 dietary treatments: basal diet (Con group), basal diet + 4 mg/kg DON (DON group), basal diet + 5 g/kg BZN (BZN group), and basal diet + 5 g/kg BZN + 4 mg/kg DON (DBZN group) for a 14-d period. Seven randomly selected pigs from each treatment were killed for blood and tissue sampling.

Results: The results showed that piglets challenged with DON exhibited significantly reduced levels of ADG, ADFI, and F/G (p < 0.05). BZN supplemented diets significantly suppressed the protein expression of p-Nrf2, p-NF-kB, and HO-1 in the intestine of DON challenged piglets (p < 0.05). In liver, DON markedly increased the mRNA expression of P70S6K and HSP70 in piglets fed the basal diet, but significantly reduced that of HO-1, NQO-1, NF-kB, AMPK╬▒2 and HSP70 in piglets fed the BZN supplemented diet (p < 0.05). Dietary supplementation with BZN markedly increased the T-AOC level of serum in weaned piglets (p < 0.05). In jejunum, dietary supplementation with BZN activated the mRNA expression of ZIP4 in piglets (p < 0.05), BZN supplementation significantly suppressed the activity of sucrose and increased the protein concentration in chyme (p < 0.05).

Conclusion: BZN can play a protective role by reducing oxidative stress and enhancing nutrition absorption in pigs fed DON-contaminated diets.
