Topic:Microencapsulation
Microencapsulation is a process that involves enclosing active ingredients within a protective coating, forming small capsules. In equine research, microencapsulation is used to deliver nutrients, medications, or supplements to horses in a controlled manner. This technique can enhance the stability and bioavailability of the encapsulated substances, allowing for targeted delivery and sustained release. Applications in horses include the administration of probiotics, vitamins, and drugs, with the aim of improving absorption and efficacy. This page compiles peer-reviewed research studies and scholarly articles that explore the methods, applications, and outcomes of microencapsulation in equine nutrition and medicine.
Absorption and dosage of theophylline in the horse after single and repeated administration of a microencapsulated preparation. The kinetics of 2 formulations of theophylline were studied in horses. In an initial cross-over study (Phase I) serum concentration-time curves were determined for granulated and microencapsulated theophylline after a single oral administration (5 mg/kg bwt). In Phase II microencapsulated theophylline was administered at 5 mg/kg bwt/12 h for 10 days at feeding time, as in normal clinical practice. Although no significant differences between the 2 preparations were found with respect to the main kinetic parameters, the microencapsulated form was more evenly and completely absorbed from the dige...
Androgens, behaviour and fertility control in feral stallions. This field study of feral stallions in Montana and Idaho examines and correlates the seasonal pattern of plasma androgens and specific sociosexual behaviour and reports the effect of a long-acting androgenic steroid on this behaviour and on fertility. Plasma testosterone was measured by competitive protein binding assay in samples obtained by jugular venepuncture from captured animals. In samples taken from 34 sexually mature stallions in 6 different months during the year, a definite seasonal pattern in testosterone was present, with a peak in May (3.04 +/- 0.63 ng/ml) and a nadir in December...
