新吉尔吉斯乳用马杂交改良伊犁马效果分析与研究

目的]通过测定新吉尔吉斯乳用马、伊犁马及其杂交F1代的体尺和体重,探析新吉尔吉斯乳用马杂交改良伊犁马的效果.方法]实验分析了新吉尔吉斯乳用马、伊犁马及其杂交F1代初生、1月龄、3月龄、6月龄、12月龄的体高、体长、胸围、管围和体重,绘制了生长发育曲线,对比和分析了三者之间的差异.结果]新吉尔吉斯乳用马、伊犁马及其杂交F1代在生长发育水平、强度及速度上差异显著.结论]杂交F1代在生长发育规律上更接近于伊犁马,而其在生长发育水平上却要优于伊犁马,说明引进新吉尔吉斯乳用马杂交改良效果明显.杂交F1代的生长速度介于新吉尔吉斯乳用马与伊犁马之间,比新吉尔吉斯乳用马慢,比伊犁马快.

Analysis and Study on the Hybrid Hores from Crossing New Kirgiz Horse (Dairy Type) with Ili Horse

【Objective】The objective of this study was to measure the body measurement and body weight of New Kirgiz horse(dairy type),Ili horse and hybrid horse so as to find out the effect of the Hybrid horse improved by crossing New Kirgiz horse with Ili horse.【Method】Body measurement(height at withers,body length,heart girth,circumference of cannon bone) and body weight were measured in 0 month age,1 month age,3 month age,6 month age and 12 month age of New Kirgiz horse(dairy type),Ili horse and hybrid horse.And then the growth curve was made,their difference were compared and analyzed.【Result】The significant difference of the growth absolute value,the growth pressure and the growth rate were remarkable.【Conclusion】Regulation of the growth of hybrid horse is similar to that of Ili horse,but the absolute value is more than that of Ili horse.It proved that improved effect of Ili Horse Hybridized by New Kirgiz horse(dairy type) is remarkable.The growth rate of hybrid horse is between the New Kirgiz horse(dairy type) and the Ili horse,slower than that of New Kirgiz horse (dairy type),faster than that of Ili horse.
