HERITABILITAS KECEPATAN LARI DAN TINGGI BADAN ANAK KUDA PACU UMUR 2 TAHUN DENGAN METODE KORELASI DALAM KELAS (INTRACLAS CORELATION)

Abstract

HERITABILITY OF SPEED AND BODY HEIGHT OF RACING HORSE AT TWO YEARS OLD USING INTRACLASS CORRELATION. This study was done to determine the heritability of speed and body height of running horse at two years old using intraclass correlation. Data used in the study were records of Indonesian racimg horse in the form of running speed of  several races with different mileage obtained from the collection of data records of race horse speed (from Steward race track in Tompaso FEKI Momuat). Note of speed run race results of the national championship race Pordasi for eleven years (1998 s / d 2012) were collected as data processed by several analytical methods to obtain the value of heritability for resistance properties. This study involved the design with intraclass correlation method used on each individual who has more than two data measurements/ weighing production. Based on the results of research and discussion, the Bunaken female offspring were faster than male offspring. The male offspring of Sabeil One Tama were faster than female offspring. The male and female offspring of Century, Champ, Decibel, and Manguni makasiouw females had the same speed. The heritability value of running speed and body height of race horse at two years old was moderate, ranging from 0.15 to 0.29 (running speed) and from 0.11 to 0.17 ( bodyheight). The height of six race horse had high positive correlation (0.815 to 0.987), indicating that the higher the height of the body, the faster running speed of horse.
