Abstract

Four blocks of Sandhills rangeland (three pastures/block) were used to test summer grazing date and fall grazing intensity effects on protein content and digestibility of fall diets. Summer treatments applied to each block were 1) no summer grazing, 2) June grazing and 3) July grazing. Each block was grazed in sequence at six different stocking rates the following fall by six esophageally fistulated cows (two per pasture). Digestibility of fall diets declined linearly and crude protein declined quadratically as fall stocking intensity progressively increased. June grazing increased the CP content of fall diets compared to July or no summer grazing, but no summer by fall grazing interactions were detected.
