Desertification and degradation of pastures has occurred over the last 50 years on the western grasslands of China due to human factors including overgrazing, unsuccessful reclamation of land, loss of soil through inappropriate cultivation, mining, population growth, and natural factors including drought. This has led to a decrease in herbage mass and a reduction in carrying capacity, leading to a reduction in the sustainability of livestock systems. One of the effects of desertification and degradation has been an increase in the area of poisonous plants over this period and these plants now cover 20.5 m ha and are now a contributing factor and symptom of the degeneration of the grasslands. The main poisonous plants that threaten livestock production are locoweeds (Oxytropis and Astragalus species), Stellera chamaejasme, Achnaterum inebrian, Cynanchum komarovii and Aconitum carmichaeli. Based on an analysis of previous and current data, this review describes the distribution of these poisonous plants and their impact on livestock production and assesses the state of poisonous plants in the western grasslands are having on the sustainability of livestock production, and addresses the issues of integrated control measures and the development of appropriate livestock management systems that could be implemented.

The survival of the extensive livestock system, the practice for most farmers in the livestock industry in Ghana depends heavily on the natural pastures as forage resource. To efficiently use the rangelands, knowledge of the species composition, especially that of poisonous plants is essential. Documented knowledge in Ghana is scanty; documentation and dissemination of the knowledge resource would enable a wider access and wider benefit to stakeholders. A study was conducted in Ghana on poisonous plants with the aim to discover the existence and diversity of poisonous plants and associated antidotes affecting livestock for documentation and preservation of knowledge. 70 different items were cited; 22 were poisonous plants for which antidotes were not cited, 28 were poisonous plants with known antidotes and 32 antidotes. There were 575 citations of plants from 194 reported cases of suspected plant poisoning, categorized as poisonous plants for which no antidotes were cited (146), poisonous plants with cited antidotes (147) and antidotes (282). 50 plants species were identified and belonged to 29 plant families. Some plants were known only by local names. There was an extensive knowledge of the diversity of poisonous plants and antidotes within the ecological zones along with possible antidotes.

Abstract Anaplasma marginale and piroplasm species are widespread among Brazilian cattle herds. Both of these tick-borne pathogens hamper livestock production and cause a significant economic impact. Although buffaloes have demonstrated a high level of adaptability, data on tick-borne pathogens are scarcely reported in Brazil. Thus, the aim of this study was to screen water buffaloes from the state of Maranhão for piroplasm and A. marginale occurrence using PCR assays. All samples were negative for A. marginale. One of the 287 (0.35%) water buffaloes tested was positive for Theileria sp. Sequencing of the 18S rDNA fragment (356 bp) showed that the Theileria sp. identified was closely related to the T. buffeli /orientalis group. Future studies on the clinical signs of infection and the main vector in this country are needed.
