I. S 24 perennial ryegrass was harvested at six stages of its growth from young leafy herbage to mature grass in which the seed had shed. 2. Two sheep were offered Ikg/d of each cut and two other sheep were offered 750 g/d of each cut of grass. 3. The contents of some possible precursors of the urinary aromatic acids excreted by sheep, namely, shikimic acid, quinic acid, chlorogenic acid, total...

Madre de Agua (Trichantera gigantean Nees) is forage and considered a Multiple Purpose Tree Species used for ruminants poultry animals with good potential source of protein contain amino acid. Few studies were conducted in terms the agronomic characteristics prior to utilization as feeds most mainly feed monogastric animals. The study intends produce data planted produces shaded portion upland ...

Twenty-four yearling Boer x Spanish goats were used in a crossover experiment to determine the effects of tethering on herbage selection, intake and digestibility, grazing behavior, and energy expenditure (EE) with high-quality herbage. Four 0.72-ha paddocks of wheat (Triticum aestivum) and berseem clover (Trifolium alexandrium) were grazed in the spring. Each paddock hosted 6 animals, 3 with f...

A 4-yr study was conducted to determine the effects of two grazing methods (GM) at two stocking rates (SR) on alfalfa pasture plant productivity and animal performance and to ascertain the effect of grazing systems on subsequent performance of steers fed a high-concentrate diet. Eight pasture plots (.76 ha) were seeded in 1988 with alfalfa (Medicago sativa L. var. WL225) and divided into two bl...

Uptake of cobalt (Co) and copper (Cu) by ryegrass/ white clover based dairy pasture from autumn spray applications of cobalt sulphate (CoSO 4 ) copper sulphate (CuSO 4 ) and Cu chelate was measured at a site near Woodlands in Southland. The rates of application were 0, 12.6, 25.2, 50.5 g Co/ha (0, 60, 120 and 240 g CoSO 4 / ha), and 0, 0.25, 0.5 and 1 kg Cu/ha. The concentration of Co in herbag...
