K. aPrincipal Components Analysis of Sward Structure and Ingestive Behaviour of Beef Cattle managed at Levels of Herbage Allowances in Natural Pasture. c2011 aThe management of herbage allowance (HA) is the main factor to adjust the requirements for the livestock production. However, the level of HA shapes the structure sward (Maraschin, 2001) and may determine different patterns of ingestive behavior. This study aimed to evaluate and to analyze by principal components of sward structure and ingestive behaviour of beef cattle grazing natural pasture in Southern Brazil. The levels of HA in natural pasture determines distinct swards structures and ingestive behaviour of beef cattle. The low HA determines a low sward structure that is possibly unfavourable to forage intake. aGrazing time aGregarious behavior aMultivariate analysis aSward height aTussock1 aNEVES, F. P.1 aPINTO, C.
