We begin by stressing that relevant and adequate information is an essential ingredient of efficient decision-making processes aimed at optimising the performance of livestock enterprises. Such decisions are universally made, so that though different approaches may be required, animal health and ...
This study documented the effect on the productivity of Dorper-Merino cross ewes when they became infected with Cowdria ruminantium as would occur in an endemically stable state. A flock of 152 breeding ewes was randomly divided into two matched groups. One group was infected on multiple occasion...
Livestock disease is only one of a number of constraints to improving productivity in smallholder systems, and research is only one approach to alleviating that constraint. However, within the correct context, animal health research that alleviates the constraint of disease can bring enormous ben...
Two experiments with 12 and 18 lactating Jersey cows respectively were carried out in the coastal semi-humid zone of Kenya to assess the performance arising from the feeding of chopped Napier fodder (Pennisetum purpureum) given ad libitum with and without one of three sources of protein; fishmeal...
Noroviruses (NoVs) and sapoviruses (SaVs), which belong to the family Caliciviridae, are important human and animal enteric pathogens with zoonotic potential. In Ethiopia, no study has been done on the epidemiology of animal NoVs and SaVs. The aim of this study was to detect and characterize NoVs...
Serum and liver retinol concentrations and blood β-carotene concentrations were studied in 30 Bos indicus heifers rendered deficient of vitamin A over 180 days and then given treatments of access to algae-based lick blocks (n = 10), injectable retinyl palmitate and molasses-based lick blocks (n =...
Brucellosis is an important zoonosis worldwide. In livestock, it frequently causes chronic disease with reproductive failures that contribute to production losses, and in humans, it causes an often-chronic febrile illness that is frequently underdiagnosed in many low- and middle-income countries,...
