Abstract
Spolnu zrelost kobile dosežu u dobi od 12 do 18 mjeseci starosti. Promjene koje dolaze s pojavom puberteta pod utjecajem su raznih hormona koje luče organi spolnog sustava. Spolni ciklus naziv je za vremensko razdoblje između dvije uzastopne ovulacije. To razdoblje traje u prosjeku 21 dan. S povećavanjem dužine dana u proljeće, kobile se počinju tjerati. Spolni žar traje prosječno 5 dana, pa je od velike važnosti pravovremeno uočiti znakove tjeranja kobila da bi se inseminacija odvila pravodobno. Prvi pripust ili osjemenjivanje treba u hladnokrvnih pasmina obaviti u dobi od dvije do tri godine, dok kod toplokrvnih pasmina u dobi od tri do četiri godine. Gravidnost počinje spajanjem spermija i jajne stanice u jajovodu, a završava porodom. Trajanje gravidnosti u kobila iznosi prosječno oko 334 do 336 dana. Dijagnoza graviditeta ima posebnu ulogu u suvremenom uzgoju i reprodukciji konja, a najčešće se korist pretraga uz pomoću ultrazvuka, te rektalna pretraga. Porod dijelimo u 3 stadija i to: stadij otvaranja, stadij istiskivanja ploda, te stadij istiskivanja posteljice.
Abstract (english)
Mares enter into puberty at the age of 12 to 18 months. Changes that become in puberty are under the influence of hormones released by reproductive system. Estrous cycle is a term for period between two consecutive ovulations. This period lasts in average 21 days. Estrous cycle in mares begins by the increasing of length of the day in the spring. The estrous phase (in heat) lasts for in average 5 days, so it is of great importance to notice the signs of the estrous phase in a timely manner so that the insemination would be at the right time. First insemination, in occidental horse breeds, needs to be done after two to three years of age, while in oriental horse breeds after three to four years of age. Pregnancy begins with binding the sperm and the egg cell in the oviduct, and ends with the birth (foaling). The duration of pregnancy in the mares is approximately 334 to 336 days. Pregnancy diagnosis has a special role in modern horse breeding and reproduction of horses. Foaling is divided into three stages: the stage of cervix opening, the stage of delivering of foal and the stage of delivery of placenta (afterbirth).
