ABSTRACT

The occurrence of heat stress in poultry houses is inevitable and leads to oxidative stress in the birds. Lycopene, a natural hydrocarbon carotenoid, possesses potent antioxidant properties. This study aimed to investigate the impact of lycopene on growth performance, meat quality, cecal microflora, and liver metabolome in broilers subjected to heat stress. A total of 480 yellow feather broilers were randomly allocated into 4 treatment groups: birds fed standard diet (Con), birds fed standard diet and supplemented with lycopene (Lyc), birds fed standard diet and subjected to heat stress (Hs), and birds fed with lycopene and subjected to heat stress (Hs-Lyc). As compared with the normal temperature groups, Hs decreased the average daily gain (ADG) of birds during d 1 to 28, lowered the pH value either in breast meat or thigh meat, increased the L* value of breast meat, and decreased the a* value of thigh meat. In comparison with non-Lyc feeding birds, Lyc supplement elevated the ADG during d 1 to 56, increased the pH of breast meat, decrease the L* and b* values of thigh meat, simultaneously increase the a* value of thigh meat. The L* of breast meat and pH of thigh meat exhibited significant differences under Hs-Lyc treatment. Lyc-treated birds exhibited higher elasticity, gumminess, and resilience in breast meat than those in non-Lyc feeding birds. The cecal metagenome analysis indicated that Hs-Lyc treatment increased the abundance of Phocaeicola salanitronis and Prevotella sp.CAG:1058, Bacteroides sp.An269, and Bacteroides sp.An19 at the species level compared with other treatments. The hepatic untargeted metabolome analysis showed that administration of Lyc upregulated 20 metabolites and downregulated 60 metabolites compared to the Con birds. Futhermore, the Hs-Lyc treatment upregulated 34 metabolites and downregulated 45 metabolites compared to the Hs birds. The correlation between the metagenome and metabolome showed that Lyc supplementation induced significant alterations in the citrate cycle, metabolism of butanoate, glycolysis/gluconeogenesis, glyoxylate and dicarboxylate, alanine, aspartate, and glutamate compared with standard supplement. In contrast, Hs-Lyc treatment induced alterations in the citrate cycle, metabolism of pyruvate, glyoxylate, and dicarboxylate, glycolysis/gluconeogenesis, arginine, proline, alanine, aspartate, and glutamate compared with the standard supplement of heat-challenged broilers. In summary, dietary Lyc supplementation promoted the growth performance, changed the meat quality, modulated the cecal metagenome and hepatic metabolome in heat-stressed broilers.
