DEVELOPMENT AND CORRELATION AMONG LIPPIZANER FOALS PER LINES
Abstract
The investigations were conducted on 114 Lippizaner breed foals in Đakovo stud. The accomplished measures obtained by cattle tape after parturition and ablactation (aged six months) referred to withers height, chest girth and cannon bone circumference per fathers' line. The foals dominance per lines varied as follows: line Favory 2, Maestoso 21, Neopolitano 5, Conversano 11, Pluto 40, Siglavy 9 and Tulipan 26 foals. The measuring values were processed by the statistical program SPSS/PC (Nie et al. 1975). Statistical processing was followed by correlation computation between aforesaid measures after parturition and ablactation in the total number of foals per line. Also, statistical significance between obtained values was also calculated. The smallest parturition withers height turned to be in the foals of the line Neapolitano 100.80 cm and the greatest one in the line Siglavy 108.11 cm. The smallest chest girth was with Maestoso line foals 80.19 cm and the largest one with Siglavy 86.78 cm. However, the smallest cannon bone circumference was found to be in Neapolitano line foals 11.10 cm and the largest one with the line Favory 12.50 cm. In the post ablactation period withers height ranged from 135.50 cm in the line Favory to 143.33 cm in Siglavy line whereas chest girth was from 133.00 cm in Favory line to 142.78 cm in Siglavy line. The smallest cannon bone circumference was also with Favory line foals 16.25 cm and the largest one with Conversano line 17.23 cm. Statistical significance of all three measures was more pronounced after parturition compared to the post ablactation period. Correlation for the total number ranged from r = -0.121 to r = 0.913. Correlation among the processed body measures ranged from very strong negative to complete positive. Stronger correlation with all the lines appeared to be between withers height, chest girth and cannon bone circumference.
