Benefits for Dominant Red Deer Hinds under a Competitive Feeding System: Food Access Behavior, Diet and Nutrient Selection
|Kateg. publikace||Vědecké publikace impaktované|
Social dominance is widely known to facilitate access to food resources in many animal species. We assessed if, even under ad libitum conditions, social rank may allow dominant hinds to consume the preferred components of food consisting of pellets of sunflower, lucerne and orange, and seeds of cereals, corn, cotton, and carob tree under competitive feeding system (limited space at the feeder). Feeding behavior and meal abundance and composition were assessed during feeding on a deer farm in Spain. Social rank was positively related to the amount of time spent feeding. Selection indices were positively correlated with energy and fat, but also negatively with certain minerals. Thus, dominant hinds could select high energy meal components for longer time under an ad libitum but restricted food access setting. Selectivity of food decreased with time. High and low ranking hinds had longer time per feeding bout than mid ones, suggesting complex behavioral feeding tactics of low ranking social ungulates.
