The abundance of legumes in grasslands is a key factor for the supply of nitrogen to associated grasses andthe contribution to the quality of the diet of ruminants. Based on the above, a study was conducted at the levelof production systems in the northern of Buenos Aires province with the aim of estimating the abundance ofwhite and red clovers in pastures and the biotic, abiotic and anthropogenic factors that may affect them. 140pastures of 2-3 years old were surveyed in 68 farms of 9 de Julio, Bolivar and Lobos counties in which red clover plant density and white clover content were estimated. For each pasture, the occurrence of diseasesand the damage due to insects on red clover roots, chemical soil properties, the technology used by the farmer in the establishment, production and pasture management were determined. The data were systematized and analyzed statistically using descriptive and inferential statistics with the SAS software. The average density of red clover plants was 6.9 plants m-2 and the average white clover coverage was 2.0%. The abundance of clovers that have been found is insufficient to support a competitive and sustainable productivity of grassland in the northern portion of Buenos Aires province. Technology of establishment and soil type were the factors most related to the density of red clover whereas technologies of production and management were the most relevant for white clover content. The factors to reverse the low abundance of legumes in pastures were identified.

Objectives: This study aims to describe a perioperative protocol for dogs recovered from anaesthesia with the owners and discharged from the hospital on the same day after surgical management of brachycephalic obstructive airway syndrome and to determine whether implementation of this protocol was associated with reduced incidence of complications compared with standard anaesthesia recovery and 24 hours hospitalisation. Materials and Methods: Medical records of dogs that underwent brachycephalic obstructive airway surgery over two consecutive years (June 2017 to May 2019) were reviewed retrospectively. Signalment, clinical signs, diagnostic findings, surgical procedures and postoperative respiratory complications were recorded. Data were compared using the chi‐squared or Fisher's exact tests. Results: Sixty‐three dogs met the inclusion criteria for the study. Forty‐two dogs underwent owner‐assisted recovery and 21 dogs standard recovery. No statistical difference was found between groups in age, breed, gender, severity of respiratory or gastrointestinal clinical signs and surgical techniques employed. The incidence of postoperative complications was higher in dogs that received standard recovery (28%) compared to dogs recovered with the owners (2%). None of the dogs recovered with the owners and discharged the same day required veterinary assistance after discharge from the hospital. Clinical Significance: Corrective surgery for brachycephalic obstructive airway syndrome was associated with lower postoperative respiratory complications when dogs were discharged on the same day after recovery with the owners. Owner‐assisted recovery and early discharge are possible and safe and may decrease the incidence of postoperative complications. However, other unmeasured factors may have contributed to the lower complication rate in dogs recovered with the owners during the course of this study. [ABSTRACT FROM AUTHOR]
