External Parasites of Horses
In Florida, horses have numerous arthropod pests. Most of these pests are considered external parasites as their attack on the horse is principally external, as opposed to internal parasites such as “worms” or nematodes and bots. The common external parasites include filth flies such as non-biting house flies and biting stable flies and occasionally horn flies, the numerous other blood-feeding ...
متن کاملSurgical Treatment of External Genital Tumors in Horses
Horses with extensive or invasive tumors of the external genitalia may require surgical intervention for successful treatment. Solitary tumors may be removed completely by local excision, laser ablation, cryotherapy, or circumferential posthectomy (i.e., reefing). Horses with advanced lesions involving the glans or body of the penis warrant phallectomy, whereas horses with infiltrative lesions ...
متن کاملInternal noise determines external stochastic resonance in visual perception
We provide the first experimental evidence that the internal noise level determines whether external noise can enhance the detectability of a weak signal. We conduct a visual detection experiment in the absence and presence of visual noise. We define three indices of external stochastic resonance effects, consider the spread of the psychometric function without external noise as an internal noi...
متن کاملInner speech captures the perception of external speech.
Talking silently to ourselves occupies much of our mental lives, yet the mechanisms underlying this experience remain unclear. The following experiments provide behavioral evidence that the auditory content of inner speech is provided by corollary discharge. Corollary discharge is the motor system's prediction of the sensory consequences of its actions. This prediction can bias perception of ot...
متن کاملAn integration of external information for foreign stallions into the Belgian genetic evaluation for jumping horses.
The aim of this study was to test the integration of external information, i.e. foreign estimated breeding values (EBV) and the associated reliabilities (REL), for stallions into the Belgian genetic evaluation for jumping horses. The Belgian model is a bivariate repeatability Best Linear Unbiased Prediction animal model only based on Belgian performances, while Belgian breeders import horses fr...
