27. TECHNIQUES TO MINIMIZE THE EFFECTS OF ACUTE HEAT STRESS OR CHRONIC IN BROILERS
ABSTRACT High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat conditioning were evaluated. The objective of this study was to evaluate the possible interactions and effects of dietary electr

35. Knowledge gaps regarding frugivorous ecological networks between birds and plants in Brazil
Abstract Vegetation stability, resilience and regeneration can be achieved by various ecological processes, the most important of which is seed dispersion. Among animal groups, birds have the largest number of frugivorous species in the Neotropics. The aim of this study was to conduct a bibliometric analysis to detect general patterns and discover knowledge
