ABSTRACT:Megaesophagus is a rare disease in ruminants characterized by regurgitation of rumen contents. In this paper
it was described cases of megaesophagus in two sheep and two goats on a farm in the state of Paraíba, Northeastern Brazil. All
animals showed regurgitation of rumen contents and weight loss, with a clinical course of several months. At necropsy all animals
presented megaesophagus. Histological examination showed segmental muscle necrosis in the esophagus and skeletal muscles.
Serum samples from one sheep and one goat were negative for the presence of blue tongue antibodies by ELISA, and whole blood
and muscle samples from one goat were negative for this virus by RT PCR. Epidemiological data and pathology suggested that the
disease could have been caused by some toxic plant, but known plants causing segmental muscle necrosis were not observed in the
areas where the disease occurred. |

ABSTRACT.
Use of climatic models to predict the El Niño/Southern Oscillation (ENSO) cycle coupled with decision support system tools can optimize management of the major crops grown in South America. AquaCrop model was applied in this paper based on field data from a soybean deficit irrigation trial in the northwestern region of Uruguay. The AquaCrop model was suitable for simulating the biomass and yield at harvest, as well as the soil water content of the soybean crop root zone, with an acceptable goodness of fit (Willmott aggregation index [IoA] > 0.80) and low estimation errors (NRMSE < 20%). After calibration and validation, AquaCrop was used to simulate 35 characteristic years for this area to analyze soybean production under irrigation and rainfed conditions, as well as to study the effect of different sowing dates and the ENSO cycle on soybean yield. This research concluded that irrigation would significantly increase the crop yield, providing stable yields for farm systems regardless of the sowing date and the ENSO cycle considered. Additionally, irrigation reducing the dependence on favorable weather for planting, allowing more flexibility in sowing date for growers. The calculated profit margins were between 6 to 36% higher using irrigation than under rainfed conditions when soybean sale price was higher than 275 US$ t?1. With lower soybean sale price, the rainfed crop may be the most desirable option for growers regardless of ENSO cycle.
