This study aims to evaluate the impact of 25% proso millet on growth performance, plasma protein profile, and nitrogen balance and to predict the releases of some greenhouse gas emissions (GES) from enteric fermentation and in the growing pig manure. During 21 days, two groups of 10 castrated male Topigs pigs with the same weight (30.48 ± 0.26 kg) and age (81 ± 3d) were fed: control (corn-triticale-soybean meal, C) or experimental (corn-proso millet-soybean meal, E). The animals were kept in metabolic cages. The GES calculation model was based on the IPCC (2016) approach, incorporating experimental parameters and prediction equations. During the analyzed period, the dietary treatment, increased (P<0.05) the growth parameters while the plasma protein profile was not significantly affected. In the E group, total nitrogen excretion (4.3%, P<0.05), and nitrogen digestibility (6.1%, P<0.05) increased while enteric CH4, g Eq.CO2 decreased (14.8%, P<0.05) vs. the C group.
