V.  aRotatinuous stockingba grazing management innovation that has high potential to mitigate methane emissions by sheep.h[electronic resource]  c2018  aTo test the hypothesis that the best sward structure in the grazing management strategy based on animal behaviour, called ?Rotatinuous? stocking, results in higher nutrient intake and lower methane emission and intensity by sheep grazing Italian ryegrass pastures, two grazing management strategies were studied: the traditional rotational stocking (RT) with pre- and post-grazing sward target heights of 25 and 5 cm, respectively and, ?Rotatinuous? stocking (RN) with pre- and post-grazing sward target heights of 18 and 11 cm, respectively. Male castrated sheep were used. The experiment was carried out in 2014 and 2015 in southern Brazil. The experimental design was a randomized complete block with four replicates. The RN treatment had better herbage chemical composition in terms of quality than that of the RT treatment, with greater (P &lt 0.05) crude protein and lower neutral and acidic detergent fibre. The ideal sward structure and greater chemical composition of Italian ryegrass pastures found under RN treatment resulted in greater herbage digestibility and intake of organic matter and metabolizable energy by grazing sheep than under the RT treatment. Our study highlights that management is the key strategy to reduce the environmental impact of grazing through lower CH4 emissions in livestock grazing systems. Rotatinuous: stocking was the more efficient grazing management strategy for mitigation of CH4 emissions and intensity by grazing sheep, with 64% less CH4 production per area and 170% less CH4 emission per unit of animal product when compared to the RT treatment.  aGreenhouse gases  aComportamento Animal  aAltura do pasto  aAzevém italiano  aIngestão de ervas  aMeia rotacional1 aSCHONS, R.
