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:
Yield gap assessments at the field-level are key for developing management practices to increase crop production in a sustainable manner. Although rice is an important food crop worldwide, yield gaps remain less investigated in Latin American rice systems. In this study, we evaluated field-level factors for closing yield gaps (based on
attainable farm yield, defined as the mean of top 10 % of farmers) for rice production in Uruguay using crop management and yield records from 2012 to 2017, covering approximately 70,000 ha per year (40 % of total rice area). The mean annual attainable yield gap ranged from 16 % to 22 % in fields with non-hybrid cultivars (90 %
of planted area) and from 14 % to 22 % in fields with hybrid rice (10 % of planted area). Early seeding was identified as the most influential factor for reducing yield gaps in both systems, followed by N rate. Stand establishment was also important for closing yield gap in non-hybrid fields, while rotation with improved pasture was important in hybrid fields. When variables were categorized as input-related, manageable, or nonmanageable, on average manageable factors (e.g. early planting and stand stablishment) were more important than input-related factors (e.g. seed or fertilizer rate). This study highlights a simple, self-contained method using large field-level datasets to quantify yield gaps and develop strategies for improving agricultural productivity. |
