Relates livestock management systems to characteristic problems facing small ruminant producers in the physical and economic environment of four states of southeast Nigeria, viz, Bendel Anambra, Imo and Rivers states. Assesses the implications of increasing population density and intensified agri...

The root of the medicinal plant Halothamnus somalensis traditionally used to treat endo-parasites of animals and humans was evaluated against endo-parasites in naturally infected goats. The goats were drenched with a crude preparation of the plant at two different doses (0.5 and 2 g/kg live weigh...

The aetiology of geophagia in periurban dairy cattle in Nigeria was assessed in relation to the mineral status of the serum, the herbage consumed, and the soil from where the herbage was consumed. The study was carried out using nine herds in the derived savannah zone during both the wet and dry ...

A linear programming model was used to analyze the effects of different herd and fodder management levels on agricultural income of small-scale mountain dairy farmers in northern Peru. Results demonstrate that fodder and herd management strongly impact farm profits. There exists considerable pote...

Ruminants adapt to periodic fluctuation in feed resources by accumulating fat stores during favourable periods. Thus, genetic variations, among ruminant genotypes, in the capa city to deposit fat could be exploited through breeding to improve animal productivity in traditional tropical production...

Contagious bovine pleuropneumonia (CBPP) is a major threat for cattle health and production in Africa. This disease is caused by the small-colony type of Mycoplasma mycoides subspecies mycoides (MmmSC). Transmission occurs from direct and repeated contacts between sick and healthy animals. Vete...
