Abstract

We studied cattle and deer diet quality within replicated grazing treatments of continuous and short-duration grazing at heavy and moderatestocking rates, The study was conducted at the Welder Wildlife Refuge, Sinton, Tex from October 1987 to July 1988, We obtained cattle diet samples from esophageally fistulated steers, Deer diets were reconstructed using data obtained through the bite-count technique, Digestibility (IVDOM) and crude protein (CP) of cattle diets were similar betweengrazing systems and stocking rates, Digestibility of deer diets was affected by both grazing systems and stocking rates, Dietary CP and IVDOM of deer and cattle diets both differed among seasons, Dietary CP levels met maintenance requirements for deer throughout the study, Also,CP levels were high enough to meet low-to mid-gestation requirements,Deer dietary protein requirements for growth and lactation were nevermet regardless of grazing strategy, Although protein content of rattle diets was relatively low, these values satisfied cattle maintenance needs, Nursing cows, however, would not have met their requirement in any season sampled regardless of grazing system or stocking rate, Continuous grazing and moderate stocking rates may provide white-tailed deer the opportunity for selecting diets containing more desirable forbsand greater nutrient concentration, Less intensive rotational grazingat moderate rates may be preferred to maintain a relatively high seral stage.
