Divergent breeding lines of Romney sheep, selected as lambs for consistently high or low faecal worm egg count (FEC) following natural multi-species challenge by nematode parasites, were established in New Zealand at Wallaceville Animal Research Centre in 1979 and at Rotomahana Station in 1985. I...

The objective of this study was to examine the effect of different concentrations of trehalose and raffinose in Tris-citric acid-glucose (TCG) egg yolk extender for the sperm freezability of Red Maasai sheep, another African breed- the Dorper and their crosses. The results showed that Red Maasai,...

African animal trypanosomosis (nagana) is arguably the most important parasitic disease affecting livestock in sub-Saharan Africa. Since none of the existing control measures are entirely satisfactory, vaccine development is being actively pursued. However, due to antigenic variation, the quest f...

The effect of millet, Pennisetum typhoideum Rich. (Poaceae), leaf nitrogen content on fitness parameters of the desert locust, Schistocerca gregaria Forsk. (Orthoptera: Acrididae), was studied under laboratory conditions. Locusts reared on high-nitrogen leaves were larger, developed faster, had h...
