An investigation was made into the epidemiology of nematode infections of sheep in two districts of Jimma zone, southwestern Ethiopia. We used two approaches—long-term monitoring of identified sheep for nematode infection and abattoir or market survey for analysis. In the first monitoring regime,...

Mucuna is an important legume for livestock feed and is widely used as a cover crop. It is particularly difficult to grow in vitro owing to the production of phenolic compounds, which oxidize the growth media within a few days and prevent plant tissues to develop. Traditional tissue culture metho...
