A Primery Study On Traits Of Idioplasmic Character Of In YiLi Horse

The research content including the growth developmental mechanism of yili horse, the rides performance research of yili horse.the breast performance research of yili horse, the meat performance research of yili horse.The results is as follows:1. The main biological character:Yili horse is described from external form,countable character and metrical proportional character by the observation of its exterior character and the measurement of traditional morphology。2. performance of riding research:riding type of the yili horse was appraisaled, speed of Yili horse was comparison with pure blood horse and Khazak horse in 1000 meter, 2000 meter, 3000 meter, 5000 meter. The yili horse is good at the long distance competition.3. This experiment is divided two parts,the first is analysis on the corrleation the Body Indices, The ages and body weight with milk Production of Yili horseThe fivteen horse was selected in zhaosu'S horse filed, The nine index of Yili horse was determined.inclding The body height X1, body lengthX2, chest girthX3, leg circleX4, hight of hinderquarterX5, width of hinderquarterX6, nipple diameterX7, ageX8, body weightX9. And Statistics nine Yili horse'S milk Production in 90, analysis on the corrleation the difference Body Indices, The body weight and ages with Milk Production of Yili horse.in order to discovered the major effect factor in milk Production of Yili horse. The body height, chest girth, width of hinderquarter, The most superior regression equation was establishmented. This multi-dimensional regression equation passeed the examination, The significantly different (P<0.05) Y=4350.72+28.97X1+32.58X3+51.37X6, The secend part is milk performance of Yili horse are compared with Oeluf and Aerd horse ,The science basis was provides for later yili horse's breast performance selection.4. Random of selection 35 Yili horses was carried on the determination and the analysis, According to 4 years old below and 4–6 year old and 6–12 year old and above 12 old four mainly ages, Yili horse was herded under all year long the condition, Yili horse average the meat of carcass is 79.7%, the rate of slaughter is 47.8%, the meat bone ratio is 3.9:1, the average live weight is 317.62 kilogram, But 4–6 old of Yili horse of the meat of carcass is 81.1%, the rate of slaughter is 49.09%, the meat bone ratio is 4.21:1, the average live weight is 308.5 kilogram, It mainly slaughters the performance index is good than other three group age stage of Yili horse, The difference is significant. after the generalized analysis, the 4–6 year-old Yili horse is suitable Slaughter age.
