|Abstract: The objective of this study was to evaluate the effects of different mineral supplements on methane emission of sheep grazing in Caatinga ecosystem. An experiment in a completely randomized design, in which 15 Santa Inês crossbred sheep (19.3 kg) were randomly assigned to one of three treatments: mineral salt for sheep (control; SALTMC), mineral salt with addition of 750 ppm of zinc per animal (SALTMZn) and mineral salt supplied with 2.5 ml of propylene glycol per kg of metabolic body weight (BW0.75; SALTMPeg). Methane emission (CH4) was performed by technique of sulfur hexafluoride tracer gas (SF6). Treatments did not affect (P>0.05) the intakes (in g/d and g/kgBW0.75) of dry matter (DM) and organic matter (OM). Methane emission, in g/d and...|
