Limited information exists on the use of zinc-l-selenomethionine (Zn-L-SeMet) in broiler diets and its effects on the growth performance, body temperature, mortality rates, blood profile, and gene expression, especially when animals are reared under cyclic heat stress conditions. This study aimed to investigate the impact of Zn-L-SeMet in broiler diets from 1 to 42 days of age reared under cyclic heat stress and its effects on growth performance, cloacal temperatures, mortality rate, blood parameters, and insulin-like growth factor 1 (IGF-1) and growth hormone receptor (GHR) gene expression in the breast muscle. A total of 1000 male Cobb 500® broiler chicks were randomly assigned to five treatments: 0, 0.

For the digestibility trial, 20 rabbits were housed in metabolic cages. The animals were distributed in two treatments, T1 (control diet without inclusion of DDGS) and T2 (control diet + 300 g kg DDGS).

- A study assessed the chemical composition and energy values of dry brewery residue (DBR) in broiler diets, finding that higher inclusions of DBR positively influenced metabolizable energy values.
- A second experiment explored how varying the amount of DBR in broiler diets affected growth performance and health metrics, showing improved weight gain and feed intake without negatively affecting overall health indicators.
- The results concluded that including up to 100 g/kg of DBR in broiler diets enhances growth during the starter phase while maintaining healthy production parameters.
