Sažetak
Body growth of a horse off spring depends on hereditary and ecological influences as well. For a proper offspring growth it is necessary to provide optimum conditions of keeping and feeding during the phase of development. These investigations were carried out in order to estimate whether there was any difference in the growth of certain body measurements of male and female foals of the Lipizzaner breed. The investigations including 274 male and 240 female foals were carried out on Đakovo stud-farm from 1957 to 1987. The measurements of the withers height, chest volume and cannons volume were performed after the birth, and at the age of 6,12,24 and 36 months. The obtained values of the measurements were processed statistically by means of the programme panel "SPSS/PC" (Nie et al, 1975). At all ages the withers height was some what larger in male than in female foals. The differences were a little more evident concerning the measuring after the birth and at the older age. The chest volume was larger in male foals after the birth, whereas it was some what larger in female foals in later phases. As expected, the cannons volume was larger in male foals in all phases of foal growth. Male foals were also charchterized by significantly larger bones compared to females. According to Rastija et al (1993) differences between male and female grown-up heads are strongly expressed. Such an equalized development of body measurements is certainly influenced by a proper feeding and keeping which is taken care of on Đakovo stud-fam. This is also supported by keeping offsprings lose on enclosures and rotation pastures.
