Summary:
Enterotoxemia caused by Clostridium perfringens type D, sometimes also called overeating disease or pulpy kidney disease, is a prevalent clostridial disease of sheep and goats. This chapter discusses the etiology, epidemiology and pathogenesis, clinical signs, diagnosis, prophylaxis, and treatment of diseases produced by C. perfringens type D. Type D enterotoxemia in sheep is a pure enterotoxemia, with no bacterial invasion of tissues, whereas in goats it may be a pure enterotoxemia, a localized enteric disease, or a combination of both. C. perfringens type D produces two typing toxins, namely alpha (CPA) and epsilon (ETX), although most type D isolates may express several other toxins. In sheep, a presumptive clinical diagnosis can be based on a history of access to heavy grain or concentrate feeding or abundant lush pasture, and clinical signs, especially in unvaccinated thriving lambs. Immunity in sheep is readily produced by vaccination, most vaccines being alum-adsorbed ETX toxoid. |

Abstract:
This trial provided information about the effects of defoliation intensity and frequency on the productivity and plant population of a plantain pasture. Despite the restrictions in plantain management, the focus is to promote its use as specialised pasture for specific purposes. Maximum herbage production was 10.9 t DM/ha/year for a frequent and severely defoliation treatment. Frequency of defoliation affected productivity at different times, mainly in spring (P=0.0013), production being promoted by frequent defoliation intervals (21 days). Plant population was affected by defoliation strategies during the year, being promoted by infrequent and lightly defoliation regimes. Previous results showed that the effects of intense defoliation increased over time, reducing plant size and density. The understanding of plantain response to defoliation regimes will contribute to increased outputs of plantain pastures and extend species persistence, and allow management strategies to be defined according to the production system. Keywords: defoliation, intensity, frequency, population |
