Cover for Effect of season on the ingestive behaviour of cattle grazing <i xmlns="http://www.w3.org/1999/xhtml">Leucaena leucocephala</i>.

The ingestive behaviour of zebu cattle was investigated at two different plant heights (90 cm=L90 and 120 cm=L120) and three seasons of the year (dry, wet and nortes). There was a significant effect (P<0.05) for the main factors. Cattle took more bites/min when grazing L90 (37) than L120 (35)....
