Abstract:
... Resolution of the existing disconnect between experts and farmers’ insights on sustainable farming requires understanding of the key factors driving farmers’ perceptions on the concept. Interviews were conducted with 160 low-input farmers to evaluate the drivers of their perceptions of sustainable ruminant farming practices in Eastern Cape Province, South Africa. It was found that farmers had nega ...

Abstract:
... Livestock markets and marketing are crucial components of the agricultural transformation agenda in Ethiopia. There is, however, little or no scientific evidence for the demand for livestock market facilities to guide the national effort. Using panel data, we estimate the effect of livestock market shed provision on market participation and revenue from small ruminants in Central Ethiopia. Experim ...

Abstract:
... Lungworms can exert a negative impact on wild ruminant fitness; for this reason, the diagnosis of the associated diseases is an important prevention measure. The Baerman–Wetzel technique is the most usual method for the diagnosis of bronchopulmonary nematodes and is based on the active migration and movement of their first-stage larvae. Pulmonary tissue samples are frequently used for the post-mor ...

The layered structure of clay minerals, however, may adsorb cations and may, thus, interfere with the ruminants’ supply of essential trace metals, such as Zn, Mn, Cu, and Fe. As quantitative knowledge about interactions between clay ingestion and essential trace metal metabolism are largely lack ...
