ADMISSION MATURITY OF YOUNG LIPIZZANER BREED YEARLING MARES

Investigations of the admission maturity in young Lipizzaner breed yearling mares were conducted on 59 heads from the stud breeding. The investigations referred to age determination of the first fertilization, first foaling and first pregnancy duration. It was determined that young Lipizzaner breed yearling mares were fertilized at the age of 1157 days or 3.17 years. First foaling took place when they aged 1489 days or 4.08 years. First pregnancy duration of the investigated yearling mares was 332.28 days. Results of the conducted investigations indicate earlier first fertilization thereby earlier foaling compared to the investigation values obtained by Rastija et al. (1988, 1989,1996, 1998 and 2000), Baban Mirjana et al. (1998 and 2005), Rimani et al. (1990) and Telalba i et al (1987). The first pregnancy lasted for 332.28 days and is mainly in accordance with values from the quoted literature (± 1 – 2 days).
