diet quality. 1. Effects of age of regrowth, strip grazing and mulching

Two experiments assessed grazing management strategies for irrigated and nitrogen- fertilised rhodes grass (Chloris gayana) cv. Callide pas-ture. In Experiment 1, the 4 treatments were: (i) open grazing of the entire paddock on a 2-week cycle (Open); (ii) grazing on a 2-week, daily strip-grazing rotation (2); (iii) a 4-week, daily strip-grazing rotation (4); and (iv) a 6-week, daily strip-grazing rotation (6). For treatments (ii), (iii) and (iv), pasture was allocated at 15 kg green leaf dry matter (DM)/cow/d and grass was mulched to a stubble height of 10 cm after grazing. Stocking rates attained were 1.7, 3.7, 3.5 and 3.4 cows/h
