Applied Studies On Selecting Racehorse In Yili Horse By The IIPA And Physical Measurement Subsection Method

In this discourse we studied the relationship between the velocity and physical measurement to confirm index in selecting the Yili horses, and discussed to select the appropriate index selecting the Yili horses in different condition. According earnings we calculated IIPA, and connected the breeders with owners using the subsection physical measurement (SPM) and IIPA. Data from:1.the agonistic performance, earnings, physical measurement of Yili horse in the Shenzheng Derby.2.Mensurated 19 SPMs of 24 Yili horses in the Urumchi equestrianism club. Using DPS statistical software analyzed the relationship between velocity and basic physical measurements, SPM. The results showed that there were correlation (P<0.05orP<0.01) between the velocity and physical tall, chest circumference, cannon, age. In the SPM, there were positive correlation (P<0.05) between the velocity and neck length, scapular length, shoulder bone length, femoral bone length, tibiae length, and negative correlation(P<0.05)between the velocity and shoulder obliquity, femoral obliquity, hipbone obliquity. Using factor analyse there were three main factors in the SPM: traction factor, sustain factor, impetus factor, then using Clustering Analyse divided 24 Yili horses into four sorts: excellent, good, middling and bad. The results of the RSPM showed that only the appropriate RSPM could gain the full out velocity. Using RSPM educed regress equation (P<0.05), and according this equation can forecast the velocity of Yili horse. The results of IIPA showed that:87 Yili horses exceeded the mean100, 25 Yili horses exceeded120, 4 Yili horses exceeded 140.Both breeders and owners could use the IIPA and SPM as criterion in selecting, dealing, washing out Yili horse. Thus they could facilitate each other to breed horse with excellent agonistic performance.
