Study On Competition Characteristics Of Different Racing Types In Yili Horse

In this study,two types of short-distance and long-distance Yili horses were selected as the object of study.17 types of foot-traits were measured in two types of horses.The data were sorted out by EXCEL and the ratio of 19 scales was calculated by using SPSS19.0,The difference between the body size and the scale of Yili was analyzed,and the key scale and scale proportion of the two types of horses were distinguished.The SPSS19.0 software was used to analyze the relationship between body size and body size index and speed the linear regression equation was established to provide data support for the breeding and improvement of Ili horses.The results are as follows:1.Comparison of the body structure of two types of Yili horsesThe results of this experiment showed that there were some differences in the structure of different types of horses.?P<0.01?.The length of rump and the depth of chest were significantly lower than those of short-distance horses?P<0.05?;the width of chest was significantly higher than that of short-distance horses?P<0.05?this reached the neck length,femur length,rump length,chest depth;chest width is the choice of long-distance,short-distance Yili horses key indicators.The body length,lumbar length,dorsal length,head length and neck length of Yili were significantly higher than those of Yili horse?P<0.05?;The thoracic index of long-haired Yili horse was significantly higher than that of short-haired Yili horse?P<0.01?;The body index of short-haired horses was significantly higher than that of long-haired horses?P<0.05?;The length of the lumbar spine,the length of the lumbar spine,the length of the head,the length of the neck,the thoracic index,and the body mass index were used as the key indicators to distinguish the long-distance Yili horses and the short-distance Yili horses.The horses'body structure of different uses has certain difference,and provides the data reference for horses'breeding of different purposes.The long-distance and short-distance Yili mares were divided into nine groups according to the maximum value of neck length,femur length,rump length,chest width,body length,lumbar vertebrae length/back length,head length/neck length,thoracic index and body index Key body and scale proportion.Long-distance,short-distance Yili mare neck length range respectively?56,61?,?61,73?;The range of femur length was?28,32?,?32,37?;The long range of rump was?45,48?,?48,52?;The range of chest width was?35,39?,?30,35?;Body length range was?96,100?,?92,96?;The length of lumbar vertebrae and dorsal aspect respectively were?0.4,0.48?,?0.36,0.4?;Head length and neck length respectively were?0.94,0.96?,?0.8,0.84?;Thorax index ranges were?64,71?,?52,60?;The range of somatosensory index was?108,114?,?114,120?.2.The correlation between body's scale and body's index and speed in1600mIn the distance of 1600m,the short-distance Yili horse and the long-distance Yili horse had extremely significant difference?P<0.01?in the scores,body height,chest circumference,body length,etc.The short-distance Yili horse was significantly higher in body height,Type Yili horses,while in body length short-haul type horses were significantly lowers than the long-haul type Yili horses.There was a significant negative correlation between the long-distance type of Yili horse and body height?P<0.01?;and significant positive correlation with body length and tube circumference?P<0.05?;the regression equation was Y₁=741.045-4.56X₁+50.00X₅-27.856X₇.?X₁ stands for body height,X₅ stands for body length,X₇ stands for tube circumference?;There was a significant negative correlation between short-distance performance and body height?P<0.01?,but negatively correlated with body length?P<0.05?.The regression equation was established by using the body ruler which had significant influence on the athletic performance.The equation was Y₁=560.172-2.665X₁-0.297X₂.?X₁ represents body height,X₂ represents body length?;3.The correlation between body's scale and body's index and speed in3000mIn the short-distance and long-distance Yili horses in performance,body height,bust and body length ratio there were significant differences?P<0.01?,The short-haired Yili horses were significantly higher than the long-distance Yili horses in the body height and bust size,while the short-haired horses were significantly lower than the long-distance type Yili horses in the body length ratio;There was a significant negative correlation between the long-distance types of Yili horse and body height?p<0.01?;and significant positive correlation with circumference?P<0.05?;and significant positive correlation with tube circumference?P<0.01?;the regression equation was established by using the body ruler which had significant influence on the athletic performance.The equation was Y₁=1419.04-7.996X₁.?X₁ represents body height?;There was a significant negative correlation between the short-distance types of Yili horse and body height?p<0.01?;which was negatively correlated with body length?P<0.05?;and significant positive correlation with circumference?P<0.05?;and significant positive correlation with the rate of chest?P<0.05?.The regression equation established by the body ruler with significant influence on the athletic performance is:Y₁=711.216-3.3236X₁+0.412X₂-0.644X₄?X₁ is the height of body,X₂ is body length,and X4 is tube circumference?.In summary,in the future production practice,the horses can be measured by the key body of the specific use of horses to select the game,while the use of body characteristics of the horse to predict the speed of the Yili horse,which can be used as a reference for early selection of Yili horses.
