Abstract

Konji su oduvijek bili tema interesa ljudi, pa su tako i upravljanje reprodukcijom konja tema brojnih istraživanja. Danas su u uporabi razne metode upravljanja spolnim ciklusom. Kobile su sezonski poliestrične živoinje, odnosno estrus se kod njih javlja nekoliko puta tijekom određene sezone. Pojava estrusa je pod utjecajem svjetlosti, ovisi o melatoninu, hormonu kojeg luči epifiza, odnosno ovisi o duljini dana, pa se estrus javlja u proljeće i u jesen. Ciklus izlučivanja melatonina vezan je za izmjenu svjetla i tame koja se događa tijekom dnevnog ciklusa od 24 sata. Od nedavno su istraživanja usmjerena na upravljanje ciklusom upotrebom plave svjetlosti. Cilj rada ovog preglednog rada je detaljno istražiti i sažeti pregled dosadašnjih istraživanja te teme i donijeti zaključke o mogućoj primjeni rješenja u Hrvatskoj. Rezultati su pokazali kako je metoda lako primjenjiva i financijski vrlo prihvatljiva te bi je trebalo pokušati primijeniti i u domaćim uzgoju konja.

Abstract (english)

Horses have always been a point of human interest, so managing the reproduction of horses has been the subject of numerous studies. Today, various methods of estrus cycle management are in use. Mares are seasonally polyester animals and estrus occurs several times during a certain season. The appearance of estrus is under the influence of light, it depends on melatonin, a hormone secreted by the pineal gland which depends on the length of the day, so estrus occurs in spring and autumn. The melatonin secretion cycle is related to the alternation of light and darkness that occurs during a 24-hour daily cycle. Recently, research has focused on cycle management using blue light. The aim of this review is to investigate in detail and summarize the previous research on this topic and to draw conclusions about the possible application of the solution in Croatia. The results showed that the method is easy to apply and financially very acceptable and should be tried in domestic horse breeding.
