Response of Phytogenic Additives on Enteric Methane Emissions and Animal Performance of Nellore Bulls Raised in Grassland

The objective of this study was to evaluate the intake and digestibility nutrients, emission enteric CH4, productive performance Nellore bulls grazing Urochloa brizantha cv. Marandu palisade grass pastures during rainy season, receiving an energy supplement or mineral supplement, with without inclusion phytogenic additives. Forty-eight were treated with: (1) additives; (2) (3) (4) Consumption total dry matter (DM), crude protein (CP), apNDF, energy; DM, CP, average daily gain; stocking rate; gain per area higher in animals consuming supplements than those supplements. Digestibility NDF, levels lower that consumed Compared supplements, supply provides nutrient intake, increases CH4 emission, improves digestibility, providing a greater performance. additives negatively affected did not reduce influenced
