Crossbred cattle (621/2–75% Holstein /Friesian or Red Dane) were grazed at Muaklek, Thailand, on a leafy, well-fertilised Pasture of Guinea grass (Panicum maximum) and Caribbean stylo (Stylosanthes hamata) and were fed concentrates twice daily at milking. The pasture contained 10–15% crude protein and provided 40% of total daily intake. A control group of 25 cattle strip-grazed the pasture for 24 hours daily. A second group grazed only at night (5 p.m.–7 a.m.); during the day they were restricted to a shaded cow-shed and fed pasture cut-and-carried from an equal area of the same pasture grazed by the control animals. During the night both groups of cattle grazed together.
