A review of kikuyu grass (Pennisetum clandestinum) poisoning in cattle.
K ikuyu grass ( Pennisetum clandestinum ) is a perennial pasture species with a spring to autumn growth habit. Although it is usually grazed without ill effect, spasmodic incidents of poisoning in cattle 1 and, to a much lesser extent, sheep 2 and goats, 3 have been encountered. The aetiology and pathogenesis of kikuyu poisoning remains poorly understood. Outbreaks are characteristically acute ...
متن کاملKikuyu (Pennisetum clandestinum) intake determined by alkanes administered in a xantham gum suspension
The alkane method of measuring herbage intake in ruminants was compared with actual intake determined by transponder-controlled feed gates (Calan gates). Kikuyu (Pennisetum clandestinum) intakes of yearling bulls (Holstein-Friesland and Hereford) were measured for a period of seven days. No significant effect of breed on intake was found. Herbage intake calculated from the alkane technique (mea...
متن کاملModelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 1. Model de®nition and parameterisation
This paper describes a Tropical Pasture Simulator. This is a simple mechanistic model representing the growth of vegetative tropical pastures under rotational or continuous grazing with responses to N fertiliser, temperature and irradiance that can be used as a tool to study management options for the development of sustainable grazing systems. The model was derived as an adaptation of the `Hur...
متن کاملParasites in sheep grazing on Kikuyu (Pennisetum clandestinum) pastures in the winter rainfall region.
Regular worm counts were done post-mortem on sheep that had grazed on Kikuyu pastures at the Elsenburg Research Station near Stellenbosch, a winter rainfall region. Major species were Trichostrongylus colubriformis, Trichostrongylus axei, while Ostertagia circumcincta was usually present in large numbers. Minor species were Haemonchus contortus, Nematodirus spathiger, Dictyocaulus filaria, Oeso...
متن کاملEffects of Kikuyu grass (Pennisetum clandestinum) age and different forage: concentrate ratios on methanogenesis Efecto de la edad del pasto kikuyo (Pennisetum clandestinum) y la relación forraje: concentrado sobre la metanogénesis
Objective. To evaluate the effect of Kikuyu grass (Pennisetum clandestinum) harvested at two different ages and three forage: concentrate supplement ratios (F/C) on methane (CH4) production, dry matter digestibility (DMD), and fermentation profile using the in vitro gas production technique. Materials and methods. six treatments, resulting from the combination of pasture age (30 or 60 days) and...
