Summary Chromium oxide and plant pigments have been used as indicators to determine herbage digestibility, fecal output, and digestible and total herbage intake for five cows rotationally and daily strip grazing alfalfa-bromegrass ( Medicago falcata

Summary Rotational and strip grazing were compared under uniform stocking rates on six acres of irrigated bromegrass ( Bromus inermis ) in 1959, 1960, and 1961. Total digestible nutrient (TDN) utilization was greater under rotational grazing througho
