Formulation of cost-effective preventive control programmes for helminth infection in small ruminants should be based on sound epidemiological knowledge of the time relationship between contamination of pastures and the seasonal availability of infective larvae in a given geographic area. Epidemi...

Examines the effect of four levels of nutrition (poor, low, medium, and high) with or without endoparasitic treatment (drenching) on postweaning growth, survival and onset of puberty in Menz ewe lambs. A concentrate mixture providing 2.5 Mcal/kg dry matter (DM) metabolizable energy and 15.2 g/kg ...

Fourty-four Borana X Friesian F1 crossbred calves born to Borana (Bos indicus) cows were randomly assigned to either suck their dams twice daily or bucket-feeding with 134 l. milk over a 57-day pre-weaning period. Their dams were also allocated either to a supplement group with grass hay ad libit...

Reviews aspects of several studies on the reproductive performance of Ethiopian Menz sheep in which plasma progesterone concentrations were monitored. The radioimmunoassay (RTA) technique has been used for determining progesterone concentration in blood and milk (Pope et al 1976; Holdsworth 1980)...
